torque CITROEN C5 AIRCROSS 2022 Handbook (in English)

Safety
Standard (ESC)
This mode is calibrated for a low level of wheel spin, based on the different levels
of grip normally encountered on the road.
Whenever the ignition is switched off, the
system automatically resets to this mode.
Snow
This mode adapts its strategy to the conditions of grip encountered for each of
the two front wheels on moving off.
(mode active up to 50 mph (80 km/h))
All terrain (mud, damp grass, etc.)
This mode, when moving off, allows considerable spin on the wheel with the
least grip to optimise clearing of the mud and to
regain grip. At the same time, the wheel with the
most grip is controlled in such a way as to
transmit as much torque as possible.
When moving, the system optimises wheel spin
to respond to the driver's requirements as fully
as possible.
(mode active up to 31 mph (50 km/h))
Sand
This mode allows little spin on the two driving wheels at the same time to allow
the vehicle to move forward and limit the risks of
getting stuck in the sand.
(mode active up to 75 mph (120 km/h))
The use of snow tyres is recommended, to
ensure that these systems remain effective
in winter conditions. All four wheels must be
fitted with tyres approved for the vehicle.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer swaying.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control (ESC) must not
have any faults.
If the system detects oscillations (snaking) in the
movement of the trailer at speeds between 35
and 100 mph (60 and 160 km/h), it acts on the
brakes to stabilise the trailer and, if necessary,
reduces the engine power to slow down the
vehicle.
The correction is signalled by the flashing of this indicator lamp in the instrument
panel and illumination of the brake lamps.
For information on the weights and towed loads,
refer to the "Technical data" section or the
registration certificate for your vehicle.
To ensure complete safety while driving with
a Towbar system, refer to the corresponding
section.
Operating fault
Should a fault occur with the system, this
warning lamp comes on in the instrument
panel, accompanied by the display of a message
and an audible signal.
If you continue to tow a trailer, reduce your
speed and drive carefully!
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The trailer stability assist system offers increased safety in normal driving,
provided that the recommendations on towing
a trailer are observed. It should not
encourage the driver to take risks, such as
towing a trailer in adverse operating
conditions (overloading, failure to observe the
trailer nose weight, worn or under-inflated
tyres, faulty braking system, etc.) or drive at
too high a speed.
In certain cases, snaking of the trailer may not
be detected by the ESC system, particularly
with a light trailer.
When driving on slippery or poor surfaces, the
system may not be able to prevent sudden
snaking of the trailer.
Advanced Grip Control
(Depending on version)
A special, patented traction control system,
which improves driveability on snow, mud and
sand. This system, optimised for operation in a range
of conditions, enables you to manoeuvre in most
slippery conditions (encountered during normal
passenger car use).
This system, which can be combined with all-
season M+S (Mud and Snow) tyres, offers a
compromise between safety, grip and driveability.
The accelerator pedal should be pressed
sufficiently to allow the system to harness the
power of the engine. Operation at high engine
speeds is completely normal.
A five-position selector knob allows you to
choose the setting best suited to the driving
conditions encountered.
An indicator lamp associated with each mode
comes on, accompanied by the display of a
message to confirm your choice.

This mode allows little spin on the two driving wheels at the same time to allow
the vehicle to move forward and limit the risks of
getting stuck in the sand.
(mode active up to 75 mph (120
km/h))
Do not use the other modes on sand as
the vehicle may become stuck.
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 operation of the engine
or of the brakes in the event of a change of
trajectory.
These systems are reactivated automatically
from 31 mph (50
km/h) and whenever the
ignition is switched on.
Recommendations
The 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:
–

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 waterway
.
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.
