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
(starting the vehicle when stuck in mud
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.
- Press the button, located on the
centre console.
- The indicator light comes on: the
ASR and ESP systems no longer act.
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
the wheels (tyres and rims), the
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.
Operation of the ASR and
ESP systems
T h e l u m i n o u s d i o d e fl a s h e s
when the ASR or ESP is
triggered.
They engage again:
- automatically above 30 mph (50 km/h),
- manually by pressing the button again. When a malfunction of the
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.
The warning light may also come on if
t h e t y r e s a r e u n d e r - i n fl a t e d . C h e c k t h e

Towing a trailer For more information about
weights, refer to the administrative
documents (V5 registration
document, ...) or to the "Weights"
section of chapter 9.
TOWING A TRAILER, CARAVAN, BOAT, ETC...
Distribution of loads
Distribute the load in the trailer so
that the heaviest objects are as
close as possible to the axle and
the nose weight is close to the
maximum authorised without, however,
exceeding it.
Cooling
Towing a trailer on a slope increases
the coolant temperature. As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.
On the contrary, use a high gear to
lower the engine speed and reduce
your speed.
In all cases, pay attention to the
coolant temperature.
Driving advice
A towed vehicle must free wheel:
gearbox in neutral.

ACCESSORIES

Good Practice
In certain cases of particularly arduous
use (towing the maximum load up a
steep slope in high temperatures), the
engine automatically limits its power. In
this case, the automatic cutting off of
the air conditioning allows the engine
power to be recovered. Tyres: check the tyre pressures
of the towing vehicle (see the
" I d e n t i fi c a t i o n f e a t u r e s " s e c t i o n o f
chapter 9) and of the trailer, observing
the recommended pressure. See the "Levels" section of chapter 7.
If the coolant temperature
warning light comes on, stop
the vehicle and switch off the
engine as soon as possible.
Brakes
Towing increases the braking distance.
Drive at a moderate speed, change
down early and brake gradually. Towbar
We recommend the use of original
CITROËN towbars and their
harnesses, which have been tested
and approved from the design stage of
your vehicle, and that you entrust the

Side wind
Sensitivity to side wind is increased.
Drive smoothly and at a moderate
speed.
ABS/ESP
The ABS or ESP systems only control
the vehicle, not the trailer or caravan.
Rear parking assistance
The assistance does not function while
the vehicle is towing. A further range is also available,
structured around comfort, leisure and
maintenance:

and safety, are all adapted to your
vehicle. A wide range of recommended
accessories and original parts is offered.
