Hill Start Assist - CITROEN C4 Handbook

Driving modes are selected using the following
control:
► Press the control to display the modes on the
instrument panel.
When the message disappears, the selected
mode is activated and remains indicated on the
instrument panel (except Normal mode).
Whenever the ignition is switched on,
Normal driving mode is selected by default.
Normal
To restore the default settings.
Eco
To reduce energy consumption by reducing the
performance of the heating and air conditioning,
without deactivating them.
Free-wheeling in Eco mode: depending on
version, with the EAT8 gearbox, switching
into "free-wheeling" is encouraged to slow the
vehicle down without using engine braking. You
can save fuel by taking your foot gradually and
fully off the accelerator pedal in anticipation of
slowing down.
To reduce consumption of the traction battery's
electrical energy by limiting engine torque.
Sport
To obtain more dynamic driving with action
on the accelerator and gear changes with an
automatic gearbox.

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.
