Citroen C4: Hill start assist
This system keeps the vehicle briefly stationary (for approximately 2 seconds) when making a hill start, while you transfer your foot from the brake pedal to the accelerator pedal.
The system is only active when:
- The vehicle is completely stationary, with your foot on the brake pedal.
- Certain slope conditions are met.
- The driver's door is closed.
Do not leave the vehicle while it is being held temporarily by hill start assist.
If someone needs to get out of the vehicle with the engine running, apply the parking brake manually. Then check that the parking brake indicator lamp and the P indicator lamp in the electric parking brake control are on fixed.
The hill start assist function cannot be deactivated. However, using the parking brake to immobilise the vehicle interrupts its operation.
Operation
Facing uphill, with the vehicle stationary, the vehicle is held for a short time when the driver releases the brake pedal:
- If first gear or neutral is engaged on a manual gearbox.
- If mode D or M is selected on an automatic gearbox.
- If mode D or B is selected on the drive selector.
Facing downhill, with the vehicle stationary and reverse gear engaged, the vehicle is held for a short time when the driver releases the brake pedal.
Malfunction
If the event of a malfunction,
these warning lamps light up on the instrument panel, accompanied by the
display of a message.
Have it checked by a CITROËN dealer or a qualified workshop.
