Peugeot Landtrek Indicators: Red Warnings (2020-present)

A red warning lamp means something needs your attention straight away. It may be a serious fault, or something simple such as an open door or an unfastened seat belt. Some red lamps come on for a few seconds when you switch on the ignition and should go off once the engine starts. If one comes on while you're driving, a warning message and an audible signal may come with it.

This guide covers the red warning lamps on the Peugeot Landtrek I (2020-present). It is and applies to vehicles built from 1 September 2022. Some lamps depend on the version or equipment fitted to your car.

Quick Reference

STOP

This is the red STOP warning lamp. It stays on, either alone or with another warning lamp, and you'll also see a message and hear an audible signal. It means a serious fault has been detected with the engine, braking system, power steering, automatic gearbox or transmission, or a major electrical fault has occurred.

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 engine coolant temperature

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

What to do:

• 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 level if needed.
• 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.

Water in Diesel fuel filter

This is the red water in Diesel fuel filter warning lamp. It stays on and a message appears on the screen when the Diesel fuel filter contains water.

What to do:

• Contact a PEUGEOT dealer or a qualified workshop without delay.
• Don't put this off, as there is a risk of damaging the fuel injection system.

12V battery charge

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

What to do:

• Stop as soon as it is safe to do so and switch off the ignition.
• With a manual gearbox, engage a gear. With an automatic gearbox, place chocks against one of the wheels.
• Clean and tighten the battery terminals.
• If the lamp does not go off when you start the engine, contact a PEUGEOT dealer or a qualified workshop.

Door(s) open

This is the red door open warning lamp. It stays on with a message showing which door is affected. Above 6 mph (10 km/h), an audible signal also sounds.

What to do:

Below 6 mph (10 km/h), the lamp and message appear without a sound:

• Close the door properly.

Above 6 mph (10 km/h), the lamp and message come with an audible signal:

• Stop somewhere safe and close the door properly.

Seat belts not fastened/unfastened

This is the red seat belt warning lamp. It stays on or flashes, depending on version, 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.

Exterior perimeter alarm and/or electronic engine immobiliser

This is the red alarm and engine immobiliser lamp. When it stays on, the alarm and/or electronic engine immobiliser has not been deactivated because the remote control has not been recognised. When it flashes, the alarm and/or immobiliser is working normally.

What to do:

If the lamp stays on:

• Lock the vehicle, then unlock it and switch on the ignition again.
• If the problem persists, contact a PEUGEOT dealer or a qualified workshop.

If the lamp is flashing:

• No action is needed, as the system is in operation.

Airbags

This is the red airbag warning lamp. When it stays on, one of the airbags or one of the pyrotechnic seat belt pretensioners is faulty.

What to do:

• Go to a PEUGEOT dealer or a qualified workshop.

Parking brake

This is the red parking brake lamp. When it stays on, the parking brake is applied or has not been fully released.

What to do:

• Make sure the parking brake is fully released before you drive off.

Braking

This red lamp warns of a braking problem and can come on in two ways. When the braking warning lamp stays on by itself, the brake fluid level has dropped significantly. When two braking icons stay on together, the electronic brake force distribution (EBFD) system is faulty.

What to do:

If the brake fluid level has dropped:

• 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 EBFD system is faulty:

• 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're not sure what it means, treat it as serious. Stop somewhere safe, read any message on the screen and check this guide or your handbook. If a red or orange lamp comes on, there may be a fault that needs further investigation, so contact a PEUGEOT dealer or a qualified workshop for advice.

Red lamps on your Peugeot Landtrek are there to protect you, your passengers and your car. Some just need a quick fix from you, like closing a door. Others mean you should stop and get help. If in doubt, stop safely and get it checked.
