Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) whenstarting on a gradient, the time it takes to move your foot from the brake pedal to the
accelerator pedal.
This s
ystem only operates when:


- the vehicle is completely stationary, with your foot on the brake pedal,

- in par ticular conditions on a slope,

- with the driver’s door closed.
The hill star t assist system cannot be
deactivated.
On an ascendin
g slope, with the vehicle
stationary, the vehicle is held for amomentarily when you release the brake
pedal:- provided you are in first gear or neutral on
a manual
gearbox,
- provided you are in position A
or M
on an electronic gear control gearbox,
- provided you are in position D
or M
on an
automatic gearbox.
Operation
On a descending slope, with the vehicle
stationary and reverse gear engaged, thevehicle is held momentarily when you
release the brake pedal.

Do not exit the vehicle while it is beingheld in the hill star t assist phase.
If you need to exit the vehicle with the engine running, apply the parking brake manually then ensure that the parking brake warning lamp (and the warninglamp P
in the lever of the electricparking brake) are on fixed(not flashing).

to place the gearbox in neutral.
In both cases, apply the parking brake toimmobilise the vehicle, unless it is programmed
to automatic mode.

If the lever is not in position P
, when thePdriver's door is opened or approximately45 seconds after the ignition is switched off, there is an audible signal and amessage appears. )
Return the lever to position P
; the audible signal stops and the message disappears.
Operating fault
When the ignition is on, a message appears in the instrument panel screen to indicate agearbox fault.
In this case, the gearbox switches to back-up
mode and is locked in 3rd
gear. You may feel a substantial knock when changing from Pto R
and from Nto R. This will not cause anydamage to the gearbox.
Do not exceed 60 mph (10 0 km/h), local speedrestrictions permitting.
Have it checked by a CITROËN dealer or aqualified workshop.
You risk damaging the gearbox:


- if you press the accelerator and brake pedals at the same time,

- if you force the lever from position Pto another position when the batteryis flat.

To reduce fuel consumption whenstationary for long periods with theengine running (traffic jam...), position
the gear lever at Nand apply theparking brake, unless it is programmed in automatic mode.
