Hill Start Assist - CITROËN C4 Handbook

Hill start assist

System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
This function is only active when:
- the vehicle is completely stationary, with
your foot on the brake pedal,
- when certain conditions of gradient are
met,
- with the driver's door closed.
The hill start assist function cannot be
deactivated.
Do not leave the vehicle while it is being
held in the hill start assist phase.
If you need to leave the vehicle while
the engine is running, apply the parking
brake manually then ensure that the
parking brake warning lamp is on (not
flashing) in the instrument panel.
Operation
On an ascending slope, with the vehicle
stationary, the vehicle is held for a brief
moment when you release the brake pedal:
- if you are in first gear or neutral with a
manual gearbox,
- if you are in position D or M with an
automatic gearbox.
On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a brief moment when you
release the brake pedal.
Operating fault
If a fault occurs with the system, these warning
lamps come on. Contact a CITROËN dealer
or a qualified workshop to have the system
checked.
