Safety
► Or, depending on version, turn the
"Grip control" knob to this position.
Deactivation is confirmed by the lighting
of this indicator lamp on the instrument
panel and the display of a message.
The ASR system is reactivated automatically
every time the ignition is switched on or at
speeds over 31 mph (50
km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and
an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
ASR/DSC
These systems enhance safety during
normal driving, but 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.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels
(tyres and rims), braking and electronic
components, as well as the assembly and
repair procedures provided by CITROËN
dealers.
In order to ensure that these systems remain
effective in wintry conditions, the use of snow
or all-season tyres is recommended. All four
wheels must be fitted with tyres approved for
your vehicle.
All tyre specifications are listed on the
tyre/paint label. For more information
on Identification markings , refer to the
corresponding section.
Grip control
(Depending on version)
A special, patented traction control system,
which improves driveability on snow, mud and
sand.
This system, optimised for operation in a range
of conditions, enables you to manoeuvre in most
slippery conditions (encountered during normal
passenger car use).
When combined with all-season 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 harness 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.
Operating modes



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.
Whenever 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 forward 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.
The ASR and DSC systems will no longer act on the operation of the engine

Driving
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►

Reduce speed immediately
, avoid excessive
steering movements and avoid sudden braking.
►

Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected may not always cause visible deformation of the
tyre.
Do not rely on just a visual check.
►

Using a compressor
, such as the one in
the temporary puncture repair kit, check the
pressures of all four tyres when cold.
►

If it is not possible to carry out this check
immediately

, drive carefully at reduced speed.
►

In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
Driving too slowly may not ensure
optimum monitoring.
The alert is not immediately triggered in the
event of a sudden loss of pressure or tyre
blow-out. This is because analysis of the
values read by the wheel's speed sensors
can take several minutes.
The alert may be delayed at speeds below
25 mph (40 km/h), or when adopting a sporty
driving mode.
The alert is kept active until the system is reinitialised.
Reinitialisation
► The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
The reinitialisation of the system is done with the
ignition on and the vehicle stationary:
–

V

ia the vehicle configuration menu for vehicles
fitted with a touch screen.
–

V

ia the button on the dashboard for vehicles
without a touch screen.
With/Without audio system



► Press and hold this button.
Reinitialisation is confirmed by a high-pitched
audible signal.
A
low-pitched audible signal indicates that
the reinitialisation operation has not been
successful.
With touch screen
► In the menu Driving / Vehicle, select
the tab "Driving functions ", then "Reset
under-inflation detection ".
►

Select "
Ye s" to confirm.
The reinitialisation is confirmed by the display of
a message and an audible signal.
Malfunction
In the event of a malfunction,
these warning lamps light up on
the instrument panel.
A message appears, accompanied by an audible
signal.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have it checked by a CITROËN dealer or a
qualified workshop.
"Space-saver" type spare wheel
The use of this type of spare wheel may
suspend tyre pressure monitoring.
In this case, the malfunction warning lamp
comes on and disappears once the wheel
has been replaced by one of uniform size (the
same as the others), the pressure readjusted
and the reinitialisation carried out.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climatic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
monitor traffic conditions, assess the distance
and relative speed of other vehicles, and
anticipate their manoeuvres before using the
direction indicator and changing lanes.

In the event of a breakdown
When the vehicle is towed with its engine off, there is no longer braking and steering assistance.
A professional recovery service must be called in the following cases:
– broken down on a motorway or main road;
– not possible to put the gearbox into neutral, unlock the steering, or release the parking brake;
– not possible to tow a vehicle with an automatic gearbox, with the engine running;
– towing with only two wheels on the ground;
– four-wheel drive vehicle;
– no approved towbar available.

Do not force the lever when pressing on
it, as if the clamp is not positioned
correctly, locking will then not be possible.
Start the procedure again.
Following reconnection
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, to enable the electronic systems to
initialise.
For right-hand drive versions, when the
total distance recorder has reached
37

miles (60 km), you must wait
approximately 15
minutes before starting the
engine.
If minor problems nevertheless persist following
this operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the relevant section, reinitialise
certain equipment:
–

Remote control key or electronic key
(depending on version).
– Sunroof and electric blind.
– Electric windows.
–

Date and time.
–


Preset radio stations.
After reconnecting the battery, the message "Collision risk detection
system fault" is displayed on the instrument
panel when the ignition is switched on. This
operation is perfectly normal. The message
will disappear while driving.
The Stop & Start system may not be operational during the trip following the
first engine start.
In this case, the system will only be available
again after a continuous period with the
vehicle immobilised, the duration of which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).
Towing
Procedure for having your vehicle towed or for towing another vehicle using the towing eye.
General recommendations
Observe the legislation in force in the country where you are driving.
Check that the towing vehicle is heavier than the towed vehicle.
The driver must remain at the wheel of the towed vehicle and must have a valid driving licence.
When towing a vehicle with all four wheels on the ground, always use an approved towbar; ropes and straps are prohibited.
The towing vehicle must move off gently.
