Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
These systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards improved control in
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The EBFD system manages the braking
pressure wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by a
reduction in the resistance of the pedal and an
increase in braking efficiency.
Anti-slip regulation (ASR)
This system optimises traction in order to
avoid wheel slip by acting on the brakes of
the driving wheels and on the engine. It also
improves the directional stability of the vehicle
on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by the
driver, this system monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Trailer stability assist (TSA)
This system allows control of the vehicle to be
retained when towing a trailer, so as to avoid
the risk of snaking.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning
lamp signals that there is a fault with
the ABS.
Illumination of this warning lamp,
coupled with the STOP and ABS
warning lamps, accompanied by
the display of a message and an
audible signal, signals that there is a
fault with the electronic brake force
distribution (EBFD).
The vehicle retains conventional braking. Drive
carefully at moderate speed.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
You must stop as soon as it is safe to do so.
Call a CITROËN dealer or a qualified
workshop.
Safety
95
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
When braking in an emergency, press
very firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
Dynamic stability control
(DSC) and anti-slip
regulation (ASR)
Activation
These systems are activated automatically
every time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation
of the engine and brakes.This is indicated by this warning
lamp flashing in the instrument
panel.
Deactivation/Reactivation
In exceptional conditions (moving a vehicle that
is bogged down in mud, stuck in snow, on loose
soil, etc.), it may prove useful to deactivate the
DSC/ASR systems, so that the wheels can
move freely and regain grip.
It is however recommended that the systems
be reactivated as soon as possible.
These systems are reactivated automatically
every time the ignition is switched off, or from
31
mph (50 km/h).
However, below 31
mph (50 km/h) you can
reactivate them manually.
To deactivate the systems, press
this button or turn the dial to this
position.
The indicator lamp in the button or dial comes
on: the DSC/ASR systems no longer act on the
operation of the engine. To reactivate the system:
Press this button.
Or Turn the dial to this position.
The indicator lamp in the button or the dial goes off.
Malfunction
Illumination of this warning lamp,
accompanied by the display of a
message and an audible signal,
indicates a fault with the system.
Contact a CITROËN dealer or a qualified
workshop to have the systems checked.

97
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability programme (ESC) must
not have any faults.
Between 37 and 99 mph (60 and 160 km/h), if
the system detects oscillations (snaking) in the
movement of the trailer, it acts on the brakes to
stabilise the trailer and, if necessary, reduces
engine power to slow down the vehicle.
For information on the weights and towed
loads, refer to the "Technical data" section or
the registration certificate for your vehicle.
To ensure complete safety while driving with
a Towbar system , refer to the corresponding
section.
Malfunction
Should a fault occur with the system,
this warning lamp comes on in the
instrument panel, accompanied by
the display of a message and an
audible signal. The trailer stability assist system
offers increased safety in normal
driving conditions, provided that the
recommendations on towing a trailer are
obser ved. It must not encourage the driver
to take additional risks, such as towing
a trailer in adverse operating conditions
(overloading, failure to obser ve the trailer
nose weight, worn or under-inflated tyres,
faulty braking system, etc.) or driving at
too high a speed.
In certain cases, the swaying of the trailer
may not be detected by the ESC system,
particularly with a light trailer.
When driving on slippery or poor sur faces,
the system may not be able to prevent
sudden swaying of the trailer.
Advanced Grip Control
Special patented traction control system which
improves driveability on snow, mud and sand.
This system, the operation of which has been
optimised for each situation, allows you to
manoeuvre in most conditions of poor grip
(encountered during passenger vehicle use).
Operating modes
The correction is signalled by the
flashing of this warning lamp in the
instrument panel and illumination of
the brake lamps.
If you continue to tow a trailer, reduce your
speed and drive carefully!
Contact a CITROËN dealer or a qualified
workshop to have the system checked. Associated with all-seasons Peak Mountain
Snow Flake tyres, this system offers a
compromise between safety, grip and
driveability.
The accelerator pedal should be pressed
sufficiently to allow the system to use the power
of the engine. Operation at high engine speeds
is completely normal.
A five-position selector knob allows you to
choose the setting best suited to the driving
conditions encountered.
An indicator lamp associated with each mode
comes on, accompanied by the display of a
message to confirm your choice.

Safety
98
Standard (ESC)
This mode is calibrated for a low
level of wheel spin, based on the
different levels of grip normally
encountered on the road.
Every time the ignition is switched off, the
system automatically resets to this mode.
Snow
This mode adapts its strategy to
the conditions of grip encountered
for each of the two front wheels on
moving off.
(mode active up to 50
mph
(80
km/h))
All terrain (mud, damp grass,
etc.)
This mode, when moving off, allows
considerable spin on the wheel with
the least grip to optimise clearing
of the mud and to regain grip. At
the same time, the wheel with the
most grip is controlled in such a
way as to transmit as much torque
as possible. When moving, the system optimises wheel spin
to respond to the driver's requirements as fully
as possible.
(mode active up to 31
mph (50 km/h))
Sand
This mode allows little spin on the
two driving wheels at the same time
to allow the vehicle to move for ward
and limit the risks of getting stuck in
the sand.
(mode active up to 75
mph
(120
km/h))
Do not use the other modes on sand as
the vehicle may become stuck.
You can deactivate the ASR
and DSC systems by turning
the knob to the " OFF" position. Recommendations
Your vehicle is designed principally to
drive on tarmac roads but it allows you to
occasionally drive on other less passable
terrain.
However, it does not permit off-road
driving such as:
-
c rossing and driving on terrain which
could damage the underbody or strip
away components (fuel pipe, fuel
cooler, etc.) due to obstacles or stones
in particular,
-
d
riving on terrain with steep gradients
and poor grip,
-
c
rossing a stream.
The ASR and DSC systems will no
longeract on the engine operation or
the brakes in the event of an involuntary
change of trajectory.
These systems are reactivated
automatically from 31
mph (50 km/h) or
every time the ignition is switched on.
Hill Assist Descent
Control
System that provides assistance when
descending on loose or soft sur faces (gravel,
mud, etc.) or a steep gradient.
This system reduces the risk of slip or loss
of control of the vehicle when descending,
whether going forward or in reverse.
During a descent, it assists the driver in
maintaining a constant speed, depending
on the gear engaged, while progressively
releasing the brakes.
Safety
99
For the system to activate, the slope must
be greater than 5%.
The system can be used with the gearbox
in neutral.
Otherwise engage a gear corresponding
to the speed to prevent the engine stalling.
With an automatic gearbox, the system
can be used with the selector at N, D or R.
When the system is regulating, the Active
Safety Brake system is automatically
deactivated.
The system is not available:
-
i
f the speed of the vehicle is above
43
mph (70 km/h),
-
i
f the speed of the vehicle is being
controlled by the Adaptive cruise
control, depending on the type of
gearbox.
Switching on
By default, the system is not selected.
The system's status is not saved when the
ignition is switched off.
The driver can select the system when
the engine is running, when the vehicle is
stationary or moving at speeds up to 31
mph
(50
km/h). F

instrument panel.
F
W
hen the vehicle begins its descent, you
can release the accelerator and brake
pedals; the system regulates the speed:
-

f the gearbox is in first or second
gear, the speed decreases and
the indicator lamp flashes rapidly,
-
i
f the gearbox is in neutral or if
the clutch pedal is depressed, the
speed decreases and the warning
lamp flashes slowly; in this case,
the maintained descent speed is
l o w e r. During a descent, with the vehicle stationary, if
you release the accelerator and brake pedals,
the system will release the brakes to set the
vehicle gradually in motion.
The brake lamps light up automatically when
the system is regulating.
If the speed exceeds 19
mph (30 km/h),
regulation is paused automatically, the indicator
lamp goes back to grey in the instrument panel,
but the indicator lamp in the button remains lit.
Regulation resumes automatically when the
speed falls below 19 mph (30 km/h) again, and
the slope and pedal release conditions are met.
You can depress the accelerator or brake pedal
again at any time.

Driving advice
Observe driving regulations and remain vigilant
whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a long journey, taking a break every two
hours is strongly recommended.
In difficult weather, drive smoothly, anticipate
the need to brake and increase the distance
from other vehicles.Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle
(engine and gearbox), the engine must be
left running for 4
minutes before driving.
Important!
Never drive with the parking brake applied
– Risk of overheating and damage to the
braking system!
As the exhaust system of your vehicle
is very hot, even several minutes after
switching off the engine, never park or run
the engine on inflammable sur faces (dry
grass, fallen leaves, etc.) – Risk of fire!
Never leave a vehicle unsuper vised with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P , depending on
the type of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle.In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
If you are obliged to drive on a flooded road:
-
c
heck that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
-
d
eactivate the Stop & Start function,
-
d
rive as slowly as possible without stalling.
In all cases, do not exceed 6 mph (10 km/h),
-
d
o not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.

New vehicle
Do not pull a trailer before having driven at least
approximately 620
miles (1,000
kilometres).
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking 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 electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system is used.
If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2
minutes after the vehicle
comes to a stop, to facilitate its cooling.

off straight away and drive at moderate
speed.
Depending on version, if the air
conditioning is activated and when the
exterior temperature exceeds 35°C,
the idle engine speed can accelerate
to reach 1,300
rpm according to the air
conditioning requirements.

conditions
(temperature below
-23°C), to ensure the correct operation
and durability of the mechanical
components of your vehicle (engine
and gearbox), leave the engine
running for 4
minutes before moving
of f.
Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. Danger of poisoning and death! With Petrol engines
, after a cold start,
preheating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to 2 minutes (accelerated idle
speed).
If the engine does not start straight away,
switch off the ignition.
Wait a few seconds before restarting the
engine. If the engine does not start after
several attempts, do not keep trying: you
risk damaging the starter motor or the
engine.
Call in a CITROËN dealer or a qualified
workshop.
To avoid any risk of jamming the pedals:
-
o
nly use mats which are suited to the
fixings already present in the vehicle;
these fixings must be used,
-
n
ever place one mat on top of another.
The use of mats not approved by
CITROËN may inter fere with access to
