Trajectory Control Systems; Snow Driving Assistance (Snow Motion); Disarming - CITROËN C5 2013 Owner's Manual

TRAJECTORY CONTROL
SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation optimises
traction to prevent skidding of the
wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability programme
acts on the brake of one or more
wheels and on the engine to keep
the vehicle on the trajectory required
by the driver.
Snow driving assistance
(SNOW MOTION)
Your vehicle has a system to help
driving on snow: SNOW MOTION.
8
This automatic system continuously
checks for situations of diffi cult sur-
face adhesion that could make it dif-
fi cult to move off or make progress
on deep fresh snow or compacted
snow.
In these situations,
MOTION system takes over from
the ASR system by optimising the
amount of wheel slip to provide the
best traction and trajectory control,
even without snow tyres and with or
without chains.
114
For vehicles with Hydractive III+
suspension, manual adjustment of
ground clearance to the intermediate
position improves further the ability
to make progress in deep snow (see
the relevant paragraph).
In extremely severe conditions (snow
on top of ice, sand, deep mud...), it
can be useful to deactivate the ESP/
ASR systems to allow a degree of
wheel spin and so recover grip.
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem.
This is indicated by fl ashing
of this warning light on the
the SNOW
instrument panel.

Disarming

In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may
be advisable to disarm the ASR and
ESP systems, so that the wheels
can move freely and regain grip.
 Press the "ESP OFF" button, lo-
cated in the centre of the fascia.
If this warning light comes
on on the instrument panel
and the indicator light on the
button comes on, this indi-
cates that the ASR and ESP
systems are disarmed.
