TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
These systems are linked and
complement the ABS.
The ASR system is very useful for
maintaining optimum drive and
avoiding losses of control of the vehicle
on acceleration.
The system optimises drive to prevent
the wheels skidding, by acting on the
brakes of the drive wheels and on the
engine. It also allows the directional
stability of the vehicle to be improved
on acceleration.
Use the ESP to hold your course
without attempting to countersteer.
If there is a variation between the
trajectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle back
on course. Disarming the ASR/ESP
systems
In certain exceptional conditions
( s t a r t i n g t h e v e h i c l e w h e n s t u c k i n m u d
or snow, or on loose ground...), it could
prove useful to disarm the ASR and
ESP systems to make the wheels spin
and regain grip.
Operating check
Good practice
The ASR/ESP systems offer increased
safety during normal driving, but
should not incite the driver to take risks
or to drive at high speed.
The operation of these systems is
ensured if the recommendations
of the manufacturer regarding
t h e w h e e l s ( t y r e s a n d r i m s ) , t h e
braking components, the electronic
c o m p o n e n t s a n d t h e fi t t i n g a n d r e p a i r
procedures within the CITROËN
network are observed.
After an impact, have these systems
checked by a CITROËN dealer.

They engage again:

systems occurs, the indicator
light comes on, accompanied
by an audible signal and a
message on the display.
Contact a CITROËN dealer to have the
system checked.

Driving safety
"Grip control" Correct use
Your vehicle is designed principally to
drive on tarmacked roads but it allows
you to drive on other less passable
terrain occasionally.
However, it does not permit all-terrain
a c t i v i t i e s s u c h a s :
- crossing and driving on terrain which
could damage the underframe or
s t r i p a w a y c o m p o n e n t s ( f u e l p i p e ,
fuel cooler, ...) due to obstacles or
stones in particular,
- driving on terrain with steep gradients and poor grip,
- crossing a stream.
When driving on snow, mud or sand,
this traction system is linked with all-
s e a s o n M + S ( M u d a n d S n o w ) t y r e s
which offer an excellent compromise
between safety, grip and traction.
This equipment allows you to
manoeuvre in most conditions of poor
grip. Pressing the accelerator pedal
s h o u l d b e s u f fi c i e n t s o t h a t t h e
power of the engine can ensure
optimum management of the various
parameters.
