Peugeot warning lights – what they mean and what do you need to do

Are you puzzled by your Peugeot's warning light? Wondering what that red dashboard symbol on your 208, 3008 or 2008 could mean? Let us help you decode your Peugeot's dashboard with the help of our handy warning light guide. 

Peugeot dashboard warning lights and symbols follow a traffic light colour system:

  • Green: the system is working correctly or is currently in use
  • Orange: something is not working correctly - take extra care and check it out as soon as possible
  • Red: there is a serious, and potentially dangerous problem - stop driving as soon as it is safe to do so

But what do all those different symbols mean? We’ve put together this guide to help you understand what the different yellow and red images on your Peugeot dashboard warning lights and symbols mean, why they come on, how urgent the problem is and what you should do when you see them.

Peugeot diesel preheat warning light

peugeot-warning-lights-glow-plug

Also known as the glow plug warning light or warming lamp light.

Glow plugs are used to preheat the engine on a diesel car.

You’ll normally see the sign illuminate when turning on the ignition as your Peugeot warms up for the drive ahead. You might notice the light as you demist your windscreen on a cold day.

Once it switches off, you’re good to go.

Can I still drive with diesel preheat warning light on?

If the light stays switched on when driving, it’s probably time to change your glow plugs.

The same applies if you notice your car repeatedly struggling to start in cold conditions, or if your vehicle tends to shake when the engine is running.

Thankfully, replacing a glow plug is a straightforward and relatively cheap job. An RAC approved garage will ensure everything’s properly taken care of.

Peugeot stop warning light

peugeot-warning-lights-stop

There’s no mistaking the stop warning light, the red icon will appear when a serious fault develops in your:

  • engine oil pressure
  • engine coolant temperature
  • braking system
  • power steering system, or
  • electrical system.

You should stop as soon as it is safe to do so, turn off your engine and seek professional help.

Can I still drive with my Peugeot stop warning light on?

In short, no. Choosing to ignore the stop warning light could cause irreparable damage to your car.

Allowing coolant temperatures to rise will mean moving parts in your engine are less lubricated and more likely to rub against other car parts causing further damage.

It’s best to follow the instructions from the sign and contact a trusted garage as soon as possible.

If you find yourself broken down on the road you can always call the RAC on 0330 159 1111 even if you’re not a member.

Peugeot service warning light

peugeot-warning-lights-service

Peugeot’s service warning light is one of the more versatile icons on your dashboard and turns on temporarily to highlight a minor fault in your car.

Minor faults might include:

  • low engine oil level
  • low screen wash level
  • low tyre pressure, or
  • minor problems in the electric parking brake

A message on the instrument panel is usually given to provide more details.

You might also notice ‘SERVICE’ illuminate at the same time as another warning light to help pinpoint a fault, for example, the electric parking brake icon or engine management light.

In some cases, the service light stays on constantly to indicate a serious fault that doesn’t have a dedicated warning light.

Can I still drive with my Peugeot service warning light on?

A permanent service warning light should be addressed as soon as possible. Most serious faults require the help of a professional so you should contact an RAC approved garage.

If the warning light only appears temporarily, the problem doesn’t need immediate attention.

Driving could even fix a minor problem in your diesel particulate filter (DPF). If the service light illuminates next to the DPF icon, driving for 10 minutes or so at speeds greater than 40mph could help to clear or regenerate the filter.

Peugeot AdBlue warning light

peugeot-warning-lights-AdBlue

Most diesel cars built after September 2015 use AdBlue to reduce their nitrous oxide emissions.

The solution made of deionized water and other chemicals helps to keep pollutants within Euro 6 emissions standards.

When the light appears on your dashboard, an audible alarm can usually be heard.

To end the alarm and turn the warning light off, simply pop your bonnet and top up the AdBlue tank with the solution recommended in your vehicle handbook.

Can I still drive with my Peugeot AdBlue warning light on?

The AdBlue warning light can appear up to 1500 miles before the solution reaches unsafe levels.

However, fixing the problem is quick and easy. If you’re unsure about how to check and top up your AdBlue, our video guide should be a helpful explainer.

Water in fuel warning light

peugeot-warning-lights-water-in-fuel

The water in fuel warning light usually features a wavy line or a droplet to indicate water and some kind of canister representing the fuel tank.

It only appears in diesel cars as their fuel systems use filters designed to remove water from fuel.

If water has entered your fuel tank your engine may work less efficiently and you might experience a noticeable drop in power.

Can I still drive with the water in fuel warning light on in my Peugeot?

It’s all down to timing. If you notice the light turn on when you’ve just topped up on diesel, the fuel may be contaminated.

You should switch the engine off as soon as it’s safe to do so to avoid damaging the injection system.

If the warning light turns on under normal driving conditions, your car should be safe to drive but should be drained as soon as possible.

In both scenarios it’s best to enlist the help of a trusted garage.

At least the problem isn’t as dangerous as putting petrol in a diesel engine. Click here for more advice after putting the wrong fuel in your car.

Peugeot foot on brake pedal warning light

peugeot-warning-lights-foot-brake

The 'foot on brake pedal light' serves two functions:

  • To let you know that you should press down on the brake before you can shift your car into drive
  • To indicate that you’ve spent too long using your accelerator to stop the car in an uphill position – it’s time to use the brake instead

In the first example, the light will remain constant. In the second, the warning light will flash.

Can I still drive with the foot on brake pedal warning light on in my Peugeot?

If the 'foot on brake light' appears when you start your engine, you won’t be able to drive without pushing down on the brake pedal. Once you do, you should be able to start your journey.

If you ignore the warning light while using the accelerator to brake on an incline, you could cause the clutch to overheat. This leaves your transmission system vulnerable to damage and could lead to a hefty repair bill.

It’s best to act safely and swiftly, and to press down on the brake as soon as possible.

Peugeot brake warning light

peugeot-warning-lights-brakes

Also known as the brake system warning light, parking brake warning light or brake fluid warning light.

If this red light remains on after you fully release the parking brake, or comes on when you’re driving, it may indicate that the brake fluid level is low. Unless you know how to check your brake fluid levels yourself, this will be one for the professionals. 

If the ABS warning light is also illuminated this signals that the braking system has malfunctioned and your brakes may not work properly. In this case the Electronic Brake Force Distribution (EBD) warning light may also be illuminated.

Can I still drive with my Peugeot brake warning light on?

You shouldn't risk it. The brakes are one of the most important safety features of your car, so it’s important to act immediately when you see this red warning light.

Pull over and stop as soon as it’s safe to do so - keep your speed low and avoid braking suddenly. Unless you know how to check your brake fluid levels yourself, this will be one for the professionals, so get yourself to a garage.

Don’t risk driving when your brakes are not functioning properly: call for recovery if you have a breakdown cover policy.

Peugeot engine management light

peugeot-warning-lights-check-engine

Also known as the MIL or engine management light.

When the engine management light is illuminated it’s often accompanied by tell-tale signs that the engine is not working properly, such as a lack of power or stuttering as you press the accelerator.

This light could indicate a number of faults, from minor issues like a broken electrical sensor to a much larger mechanical issue, like a fault with your emission control system or catalytic converter.

How long can I drive with my check engine light on in my Peugeot?

If the check engine light comes on you should get it checked as soon as you can, as by continuing to drive you risk causing further, potentially irreparable damage to your engine. 

Use our search tool to find your nearest RAC approved garage, or why not use an RAC Mobile Mechanic. Or, if you have RAC Breakdown Cover, call for recovery.

Peugeot airbag warning light

peugeot-warning-lights-airbag

Also known as the supplemental restraint system (SRS) or safety system warning light.

When this light goes red it means that at least one element of the airbag safety system is not working correctly: either the airbag system itself; the front passenger occupant classification system (which detects the front passenger’s weight and position in order to safely deploy the airbag); or the seat belt pretensioner system, which tightens the belt in the event of a crash.

Can I still drive with my airbag light on in my Peugeot?

If the airbag system is not working properly, it may not go off in a crash - or in some cases it could even deploy unexpectedly and cause a crash. Either way, the airbag system is an incredibly important safety feature of your car so if this light comes on please get it checked out immediately.

Peugeot power steering warning light

peugeot-warning-lights-power-steering

Also known as the EPS (Electric Power Steering) warning light

This warning light indicates that there’s a problem with the power steering and on Audi dashboards, it sometimes appears without an exclamation mark.

For electric powered systems, this problem could be as simple to fix as rebooting a computer. Find a safe place to stop and try turning the car off and back on again after 30 seconds. If the light stays on you should take your car to get checked as soon as possible.

Can I drive with my Peugeot EPS light on?

You can but if the power steering system fails you will notice that the car is harder to manoeuvre and you should take extra care – it could be dangerous to drive at high motorway speeds without power steering assistance.

Find a garage

Peugeot diesel particulate filter warning light

peugeot-warning-lights-dpf

Also known as the DPF or exhaust particulate filter warning light.

If you have a diesel, one of these lights will come on if there is a problem with the exhaust particulate filter, which removes harmful soot from the exhaust gases to reduce emissions. It could indicate that the filter has become blocked with soot.

Can I still drive with my DPF light on in my Peugeot?

As well as releasing a plume of toxic black smoke every time you press the accelerator, driving with a blocked filter could cause more serious damage to your car. You should go to a garage to get it checked as soon as you can, as these filters can be expensive to replace.

Peugeot coolant warning light

peugeot-warning-lights-coolant

Also known as the engine temperature warning light.

This light will come on when the engine is overheating. This could mean that coolant levels are running low, perhaps due to a leak in the system, or it could be a sign of a larger problem, like a head gasket failure.

Can I still drive with my engine overheating light on in my Peugeot?

If this light is red you should stop straight away, as without enough coolant your engine could get so hot that it effectively welds itself together, causing irreparable damage.

Stop and wait until the engine has cooled off before checking the gauge on the side of the coolant tank under the bonnet, topping up as required. 

While you’re under the hood, have a look to see if there are any obvious leaks. If you can’t see any and the light goes off after topping up then you should be fine to continue your journey. If the light comes back on again after topping up you should get it checked out to fix the underlying problem. 

An overheating engine can cut out as well. Rather than risk it, you should call for recovery if you have breakdown cover.

Peugeot oil warning light

peugeot-warning-lights-oil

This yellow or red light is also known as the low engine oil or low oil pressure light.

The oil warning light comes on when either the oil temperature gets too high or the oil level or pressure is too low. If the oil is not lubricating the engine effectively it could lead to expensive or even irreparable engine damage, so it’s important to act quickly.

Can I still drive with my low engine oil light on in my Peugeot?

When this light comes on you should stop as soon as possible and turn off the engine. Have a look for any obvious oil leaks under the car, and then check the oil levels, topping up if necessary.

If the oil levels are fine, then the oil pump may be faulty. In this case call for recovery if you have breakdown cover, as driving any further could damage the engine. Watch our video guide to checking your car’s engine oil.

While you’re under the hood, have a look to see if there are any obvious leaks. If you can’t see any and the light goes off after topping up then you should be fine to continue your journey. If the light comes back on again after topping up you should get it checked out at a garage to fix the underlying problem.

Peugeot tyre pressure monitoring system

peugeot-warning-lights-tyre-pressure

Also known as the run flat indicator RPA or low tyre pressure warning light

Many Audis are now fitted with tyre pressure monitoring systems that will let you know when the pressure falls. This could happen over time or it could be because of a puncture.

Can I still drive with my tyre pressure light on in my Peugeot?

Yes, but you should drive with extra care and aim to top up with air at the next opportunity. Low tyre pressure can cause unsafe driving conditions so reduce your speed, and try to avoid braking suddenly or making any violent steering manoeuvres.

Most petrol stations and garages will have an air compressor you can use to check your tyre pressure. Top up the air in the tyres according to the vehicle manufacturer specification in your owner's manual. 

If you have a puncture, watch our video to learn how to change a tyre in 10 simple steps.

Peugeot battery warning light

peugeot-warning-lights-battery

Also known as the battery charge light or battery charging system light.

If this light comes on when you’re driving it indicates that the battery is not charging. This could be due to a problem with your car’s electrical system and it could have several causes, such as a faulty alternator, faulty battery, bad electrical connection or damaged cabling.

Can I still drive with my battery charging system light on in my Peugeot?

Your car will run as normal until the battery is dead but once it is drained nothing in your car will work – so get to a garage quickly before you run out of juice!

If you do run out of charge, you can try to jump start it, or call for recovery if you have RAC Breakdown Cover.

Peugeot anti-lock brake system (ABS) warning light

peugeot-warning-lights-abs

ABS is an important safety feature that really comes into play when you need to make an abrupt stop, or in difficult driving conditions like icy roads.

Can I still drive with my ABS light on in my Peugeot?

If the ABS light comes on by itself you should still have normal, unassisted braking, so it's safe to continue your journey – but keep your distance, take extra care, and get it checked as soon as possible.

If it comes on with the brake warning light, it could indicate that the brake system is failing and you should stop straight away and call for recovery if you have breakdown cover.

For roadside assistance, you can call the RAC on 0330 159 1111 even if you’re not a member.

Peugeot electronic stability problem (ESP) or dynamic stability control DSC warning light

peugeot-warning-lights-stability

Also known as Electronic Stability Control (ESC).

This warning light sometimes appears as the initials ESP and indicates a problem with traction control. If it’s flashing it means the ESP system is intervening – for example, if you’re driving on a slippery road. If the light stays on it means the ESP system is not working properly.

The ESP light will light up with the word ‘OFF’ if the system has been deactivated, in which case you may have inadvertently turned it off.

To check, try stopping and restarting the engine. If the light remains on after restarting get it checked at a garage as the ESP system is an important safety feature.

Peugeot brake pad warning light

peugeot-warning-lights-brake-pad

Also called the brake pad wear warning light, if this symbol shows up it means a sensor has detected your brake pads are too thin.

Can I drive with my brake pad light on in my Peugeot?

This warning light should come on before the brake pads become dangerously thin, so you have time to get them changed. You should replace as soon as you can though, as if they wear out completely it could be extremely dangerous.
