Peugeot Expert Indicators: Red Warnings (2016-2024)

Red warning lamps on your Peugeot Expert III van point to a fault or a situation that needs your attention straight away. Some of them come on for a few seconds when you switch on the ignition and should go off as soon as the engine starts. If a red lamp stays on or comes on while you are driving, there may be a fault that needs further investigation.

This guide covers the Peugeot Expert III van built between 2016 and 2024 and applies to vehicles built from 1 December 2022. Some lamps only appear on certain versions or depend on the equipment fitted to your van.

Quick Reference

STOP

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

What to do:

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

Maximum engine coolant temperature

Depending on your van, this shows as a red coolant temperature warning lamp or an LED. It comes on steadily, and on some versions the temperature needle also moves into the red zone. It means the temperature of the cooling system is too high.

What to do:

• Stop the van 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 needed (Diesel).
• 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 steadily, there is a fault with the engine lubrication system.

What to do:

• Stop the van 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 red system malfunction lamp applies to electric versions. When it comes on steadily, a fault involving the electric motor or the traction battery has been detected.

What to do:

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

Battery charge

This is the red battery charge warning lamp. When it stays on steadily, there is a fault in the battery charging circuit, for example dirty battery terminals or a slack or broken alternator belt.

What to do:

• Clean the battery terminals and tighten them again.
• 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

Depending on your version, this shows as a red seat belt reminder lamp. It comes on steadily or flashes, together with an audible signal that gets louder. It means a seat belt has not been fastened or has been unfastened.

What to do:

• Make sure every occupant fastens their seat belt.

Door open

This red lamp shows that something is open. It comes on steadily with a message telling you which opening is open, and above 6 mph (10 km/h) an audible signal sounds as well. Depending on your version, it means a door, the boot, the tailgate or the opening rear screen is still open.

What to do:

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

Electric parking brake

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

What to do:

If the lamp is on steadily:

• Release the electric 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. With an automatic gearbox or drive selector, select mode P.
• Switch off the ignition and contact a PEUGEOT dealer or a qualified workshop.

Manual parking brake

This red lamp relates to the manual parking brake. When it is lit steadily, the parking brake is applied or has not been fully released.

What to do:

• Release the parking brake fully before you drive off.

Braking

This red braking lamp can come on for two different reasons. If the braking warning lamp comes on steadily on its own, the brake fluid level in the braking circuit has dropped significantly. If the braking lamp comes on steadily together with a second symbol, the electronic brake force distribution (EBFD) system is faulty.

What to do:

If the lamp shows a low brake fluid level:

• Stop the van 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 lamp shows an EBFD fault:

• Stop the van 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 you are not sure what a red lamp means, look at any message on the screen and listen for an audible signal, as these help you tell a normal situation from a fault. When in doubt, stop somewhere safe, switch off the ignition and contact a PEUGEOT dealer or a qualified workshop.

Red lamps are your Expert III telling you something needs attention now, so it pays to act on them promptly. Keep this guide handy, and check your handbook for full details on each system fitted to your van.
