Reactivation Of The Asr; Deactivation Of The Asr - CITROEN C4 Spacetourer Handbook

In emergency braking, press the brake
pedal hard and maintain this pressure.
After an impact, have these systems
checked by a CITROËN dealer or
a qualified workshop.
Anti-slip regulation (ASR)/
Dynamic stability control
(DSC)
Operation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of
a problem with grip or trajectory.
This is indicated by flashing of this
warning lamp in the instrument
panel.

Deactivation of the ASR

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
Reactivate the system when grip conditions
allow.
F In the Driving menu, select the "Driving
functions" tab, then "Traction control".
Deactivation is confirmed by the display of
a message.
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.

Reactivation of the ASR

The system is reactivated automatically every
time the ignition is switched back on or from
31 mph (50 km/h).
Below 31 mph (50 km/h), you can reactivate it
manually:
F In the Driving menu, select the "Driving
functions" tab, then "Traction control".
Operating fault
The illumination of this warning
lamp, accompanied by an audible
signal and a message, indicates that
there is a fault with these systems.
Contact a CITROËN dealer or a qualified
workshop to have the systems checked.
ASR/DSC
These systems offer increased safety
in normal driving, but they should not
encourage the driver to take extra risks or
drive at high speed.
It is in conditions of reduced grip (rain,
snow, ice) that the risk of loss of grip
increases. It is therefore important for your
safety to keep these systems activated in
all conditions, and particularly in difficult
conditions.
The correct operation of these systems
depends on observation of the
manufacturer's recommendations, not
only about the wheels (tyres and rims),
braking and electronic components but
also the assembly and repair procedures
used by CITROËN dealers.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.
