Peugeot Expert Indicators: Red Warnings (2024-2025)

Warning and indicator lamps on your dashboard either warn you of a malfunction or show you the operating status of a system. If a red lamp comes on, there may be a fault that needs further investigation, and it may be accompanied by an audible signal or a message on the screen. Some red lamps come on for a few seconds when you switch on the ignition. This is normal, and they should go off as soon as the engine starts.

This guide covers the red warning lamps on the Peugeot Expert III van (2024-2025) and applies to vehicles built from 4 March 2024. Some lamps only appear on certain versions or depend on the equipment fitted to your van.

Quick Reference

STOP

This is the red STOP warning lamp. It stays on together with another warning lamp, a message and an audible signal. It means a serious fault has been detected with the engine, braking system, power steering or automatic gearbox, or a major electrical fault has been found.

What to do:

• Stop as soon as it is safe to do so and switch off the ignition.
• Contact a PEUGEOT dealer or a qualified workshop.

Maximum coolant temperature

This is the red coolant temperature warning lamp. When it stays on, the temperature of the cooling system is too high.

• Stop as soon as it is safe to do so and switch off the ignition.
• Wait until the engine has cooled down, then top up the coolant if necessary.
• If the problem persists, contact a PEUGEOT dealer or a qualified workshop.

Engine oil pressure

This is the red engine oil pressure warning lamp. When it stays on, there is a fault with the engine lubrication system.

What to do:

• Stop as soon as it is safe to do so and switch off the ignition.
• Contact a PEUGEOT dealer or a qualified workshop.

System malfunction (Electric)

This is the red system malfunction warning lamp for electric versions. When it stays on, a fault involving the electric motor or the traction battery has been detected.

What to do:

• Stop as soon as it is safe to do so and switch off the ignition.
• Contact a PEUGEOT dealer or a qualified workshop.

12 V battery charge

This is the red 12 V battery charge warning lamp. When it stays on, the battery charging circuit is faulty. Possible examples are dirty battery terminals or a loose or severed alternator belt.

What to do:

• Stop as soon as it is safe to do so and switch off the ignition.
• Clean the battery terminals and tighten them.
• If the lamp does not go off when you start the engine, contact a PEUGEOT dealer or a qualified workshop.

Seat belts not fastened/unfastened

This is the red seat belt warning lamp. It comes on steady or flashing, with an audible signal that gets louder. It means a seat belt has not been fastened or has been unfastened, depending on the version.

What to do:

• Make sure every seat belt in use is fastened.

Door open

This is the red door open warning lamp. It stays on with a message telling you which access is open, and an audible signal is added if you are travelling faster than 6 mph (10 km/h). It means a door, the boot, the tailgate or the opening rear screen is still open, depending on the version.

What to do:

• Close whichever door or access is open.
• If your van has a right-hand side-hinged door, bear in mind that this lamp will not warn you when that door is open.

Electric parking brake

This is the red electric parking brake lamp. When it is steady, the electric parking brake is applied. When it flashes, applying or releasing the parking brake is not working properly.

What to do:

If the lamp is steady:

• Release the parking brake before you drive off.

If the lamp is flashing:

• Stop as soon as it is safe to do so and park on flat, level ground.
• With a manual gearbox, engage a gear, then switch off the ignition.
• Contact a PEUGEOT dealer or a qualified workshop.

Manual parking brake

This is the red parking brake lamp, the same symbol used for the braking warning. When it stays on, the manual parking brake is applied or has not been fully released.

What to do:

• Release the parking brake fully before you drive off.

Braking

This is the red braking warning lamp. When it stays on by itself, the brake fluid level in the braking circuit has dropped significantly. When it stays on together with the second symbol shown above, the electronic brake force distribution (EBFD) system is faulty.

What to do:

If the braking lamp is on by itself (low brake fluid):

• Stop as soon as it is safe to do so and switch off the ignition.
• Top up the brake fluid with fluid that meets the manufacturer's recommendations.
• If the problem persists, contact a PEUGEOT dealer or a qualified workshop.

If the braking lamp is on with the second symbol (EBFD fault):

• Stop as soon as it is safe to do so and switch off the ignition.
• Contact a PEUGEOT dealer or a qualified workshop.

If You're Not Sure

If a red lamp comes on and you are not sure what it means, look at whether it is steady or flashing, and check for any message on the screen or an audible signal, as these help you tell a normal situation from a fault. Stay calm, stop somewhere safe if you need to, check the relevant section of your handbook and contact a PEUGEOT dealer or a qualified workshop if you are still unsure.
