A Guide to the Picasso Warning Lights
As part of a self-check, many dashboard warning lights come on temporarily with the ignition switch to ON and/or when the engine has just started. This is normal procedure. A colour scheme is associated with the type of light that comes on your dashboard. Your Picasso warning lights are there to inform something is:
- in operation – these are blue or green symbols
- is switched off – these are usually amber or yellow symbols
- requiring maintenance – these are usually amber or yellow symbols
- at fault – these will usually be red symbols, possibly flashing and may have an audible alarm
If whilst driving a dashboard warning light comes on in amber / yellow or more importantly in red and you’re unsure what it is, it would be advisable to stop when safe to do so and switch off the engine. Investigate the meaning of the warning to determine what action is required.
Certain warning lights may prevent you from continuing your journey as there may be significant risk of damage to vehicle components and/or potential risk to the safety of vehicle occupants.
Citroën C4 Picasso / Grand C4 Picasso Dashboard Warning Lights
You’ll find the majority of the dashboard warning lights for both the Citroën C4 Picasso and Grand C4 Picasso along with their meaning and an explanation of what action to take.
Name: Auto Headlights
Description: This symbol indicates that the Citroën C4 Picasso / Grand automatic headlight dipping is active. Function is activated / deactivated in the driver assistance menu.
Action: System is managed by a camera located in the door mirrors. If the system fails to operate, ensure the camera is clean and free from dirt.
Name: Glow Plugs
Description: On diesel versions of the Picasso only, glow plugs are heating devices that aid in starting the engine. Before attempting to start the engine, switch the key to on and wait for the glow plug pre-heat light to go out. In warmer climates, the glow plugs light may not illuminate whereas in very cold climates, the light may stay on for up to 30 seconds before the engine is ready to start.
Action: If the Picasso glow plugs light doesn’t come on and you’re experiencing trouble starting the engine, or the engine is excessively rough at start-up, have the vehicle checked for faults with a code reader. The likely cause is faulty glow plugs or glow plugs relay, though other more complicated faults such as fuel injectors can also cause this issue.
Name: Electric Parking Brake
Description: The electric parking brake red symbol (steady light) illuminates on the Citroën C4 Picasso / Grand dashboard indicating that it has been applied.
Action: There are two instances where the electric parking brake flashes:
- When driving, the electronic parking brake is not fully released. A quick press on the control lever should release the brake. If the light remains on, contact a Citroën specialist.
- When stationary and parked, the light will flash indicating that the electronic parking brake does not guarantee immobilisation of the vehicle. This could be due to being parked on a steep slope for example. To secure the vehicle, leave it in gear for manual or select P with an automatic gearbox.
Name: Parking Brake Fault
Description: If the electronic parking brake light with an exclamation mark illuminates in amber, it means there’s a malfunction with the system.
Action: Automatic release of the parking brake may not be available. Use the lever to manually release.
Name: Parking Brake Deactivation
Description: This symbol indicates that the automatic functions of the electronic parking brake have been deactivated. It’s advisable that in certain conditions such as very cold weather (risk of freezing) or towing a caravan, that the automatic functions of the electronic parking brake be disabled.
Action: To deactivate the automatic functions of the electronic parking brake:
- Start the engine.
- Apply the parking brake with the control lever (if it is released).

Description: ABS or anti-lock braking system became compulsory for all car manufactured in Europe from 2004. In the event of heavy braking, ABS kicks in to prevent the wheels from locking up. This in turn allows the driver to continue to steer.
Action: If the ABS lights up on your Citroën Picasso dash, it means the system has malfunctioned. Standard brakes are not affected, but you will be at higher risk of skidding and a greater loss of control under harsh braking.
Description: The red BRAKE warning light and the ABS amber light illuminating simultaneously indicates a fault with the Electronic Brake Force Distribution (EBFD). EBFD is an additional safety feature that works with ABS to control the amount of braking on each individual wheel.
Action: As with ABS, EBFD does not affect your standard brakes but will put your vehicle under greater risk of a loss of control under heavy braking.
Description: DSC ‘Dynamic Stability Control and ASR ‘Anti-slip Regulation’ and linked to ABS to help maintain stability of your Citroën C4 Picasso. It also allows the directional stability of the vehicle to be improved on acceleration. If the light comes on, it means that the system is in operation.
Action: If the light flashes, it indicates a fault and should be checked by an authorised engineer.

Temporarily: A minor fault has occurred but not associated with any specific warning light. Faults will be identified by the messages:
- opening of a door, the boot or bonnet,
- low engine oil level,
- low screenwash/headlamp wash fluid level,
- discharged remote control battery,
- low tyre pressures,
- saturation of the particle emission filter (PEF) on diesel vehicles – see below.
Constantly: A major fault has occurred and can be identified by a message.
Name: SERVICE PEF
Description: SERVICE light in association with the particle emission filter (PEF) on diesel vehicle.
Action: On diesel versions of the Citroën Picasso, the diesel particulate filter may require cleaning. When traffic conditions permit, regenerate the filter by driving at a speed of at least 40 mph (60 km/h) until the warning lamp goes off. If the warning lamp stays on, this indicates a low additive level.
