Associated systems which contribute to the directional stability of the vehicle within the limits of the laws of physics:
- t raction control (TCL),
-

a
ctive stability control (ASC).
Traction control and active stability control
Traction control optimises traction to prevent
wheel spin, by acting on the brakes of the
driving wheels and on the engine.
Active stability control acts on the brake of one
or more wheels and on the engine to keep the
vehicle on the trajectory required by the driver.Activation
These systems are activated automatically
each time the vehicle is started.
The illumination of this warning lamp
in the instrument panel indicates
that the ASC and TCL systems are
deactivated.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, ...), it may be advisable to deactivate
the ASC system, so that the wheels can move
freely and regain grip.
This is indicated by the flashing of
this symbol on the instrument panel
screen.
Trajectory control systems
F Press this button, located to the right of the steering wheel, until the symbol appears in
the instrument panel screen.
Operation
They operate when the vehicle speed is higher
than 9 mph (15 km/h).
They come into operation in the event of a grip
or trajectory problem.

Advice on driving when towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without
exceeding
it.
Air density decreases with altitude,
thus
reducing engine per formance. Above
1
000 metres, the maximum towing load must
be reduced by 10
% of the GTW and so on for
every 1
000 metres of altitude.
For more information on Petrol weights or
Diesel weights and in particular the towed
loads which apply to your vehicle, refer to the
corresponding section.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long slope
depends on the gradient and the exterior
temperature.
In all cases, pay attention to the coolant
temperature.
F

I
f this message is displayed, stop your
vehicle as soon as it is safe to do so.
Braking
Towing a trailer increases the braking distance.
To limit heat build-up in the brakes, use of the
engine brake is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the lighting and signalling on the trailer and the adjustment of the vehicle's
headlamps.
For more information on Headlamp
adjustment , refer to the corresponding
section.
If the message flashes slowly, wait for the
engine to cool before topping up the level, if
necessary.
If the message flashes rapidly, contact a
CITROËN dealer or a qualified workshop
without delay.
The rear parking sensors will be
deactivated automatically when a
genuine CITROËN towbar is used.
Practical information

188
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to have
the condition of the brakes checked,
even between vehicle services.
Brake pads
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Brake disc wearParking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
