Hill Assist Descent Control - CITROEN C5 AIRCROSS Handbook

Safety
You can deactivate the ASR
and DSC systems by turning
the knob to the "OFF" position.
The ASR and DSC systems will no longer
act on the engine operation or the brakes
in the event of an involuntary change of
trajectory.
These systems are reactivated
automatically from 31 mph (50 km/h) or
every time the ignition is switched on.
Recommendations
Your vehicle is designed principally to
drive on tarmac roads but it allows you to
occasionally drive on other less passable
terrain.
However, it does not permit off-road
driving such as:
- crossing and driving on terrain which
could damage the underbody or strip
away components (fuel pipe, fuel
cooler, etc.) due to obstacles or stones
in particular,
- driving on terrain with steep gradients
and poor grip,
- crossing a stream.

Hill Assist Descent
Control
System that provides assistance when
descending on loose or soft surfaces (gravel,
mud, etc.) or a steep gradient.
This system reduces the risk of slip or loss
of control of the vehicle when descending,
whether going forward or in reverse.
During a descent, it assists the driver in
maintaining a constant speed, depending
on the gear engaged, while progressively
releasing the brakes.
For the system to activate, the slope must
be greater than 5%.
The system can be used with the gearbox
in neutral.
Otherwise engage a gear corresponding
to the speed to prevent the engine stalling.
With an automatic gearbox, the system
can be used with the selector at N, D or R.
When the system is regulating, the Active
Safety Brake system is automatically
deactivated.
The system is not available:
- if the speed of the vehicle is above
43 mph (70 km/h),
- if the speed of the vehicle is being
controlled by the Adaptive Cruise
Control, depending on the type of
gearbox.
Operation
Switching on
By default, the system is not selected.
The state of the function is not saved when the
ignition is switched off.
The driver can select the system when
the engine is running, when the vehicle is
stationary or when moving at speeds up to
approximately 31 mph (50 km/h).
With instrument panels with dials
F To select the system, at a speed
below 31 mph (50 km/h), press
this button until its indicator lamp
comes on; up; this indicator lamp
appears in green in the instrument
panel.
