Malfunction
The illumination of this warning
lamp, accompanied by an audible
signal and a message, indicates that
there is a fault with the system.
After an impact, have the system checked
by a CITROËN dealer or a qualified
workshop. ASR/DSC
These systems offer increased safety
in normal driving, but they 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.
The correct operation of these
systems depends on obser vation of
the manufacturer's recommendations
regarding as much the wheels (tyres and
rims), braking and electronic components
as the assembly and repair procedures
used by CITROËN dealers.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Grip control
Special patented traction control system which
improves traction on snow, mud and sand.
This system, whose operation has been
optimised for each situation, allows you to
manoeuvre in most conditions of poor grip
(encountered during use of a passenger car).
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 to confirm your choice.
Associated with all-seasons Peak
Mountain Snow Flake tyres, this system
offers a compromise between safety, grip
and traction. They are efficient in winter
and summer conditions.

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.F

P
lace the knob in this position.
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))
F

P
lace the knob in this position.
All road (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 30
mph (50 km/h))
F

P
lace the knob in this position.
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))
F

P
lace the knob in this position.
Do not use the other modes on sand as
the vehicle may become stuck. You can deactivate the ASR
system by turning the knob to
the "
OFF" position.
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.
This system is reactivated automatically
from 30 mph (50 km/h) or every time the
ignition is switched on.
Driving 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.
Safety

97
Hill Assist Descent
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.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 enters regulating
mode, the Active Safety Brake system is
automatically deactivated. The system is no longer available if the
speed of the vehicle is above 30 mph
(50 km/h).
Operation
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 30 mph (50 km/h)
.
F With the speed below 30 mph
(50 km/h), press this button
until its indicator lights up to
select the system; this indicator
lamp appears in green in the
instrument panel.
The system becomes active at a speed below
20 mph (30 km/h). F

W
hen the vehicle begins its descent, you
can release the accelerator and brake
pedals, the system regulates the speed:
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 20 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 20 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. -

i
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
indicator lamp flashes slowly;
in this case, the maintained
descent speed is lower.

Driving recommendations
Observe the 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 must only carry
out any operations that require close attention
when the vehicle is stationary.
On a long journey, 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 and gearbox, as well as to the
electrical systems of your vehicle. If you must drive through water:
-

c
heck that the depth of the water is not
more than 6 inches (15 cm), allowing for any
waves that might be made by other road
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 and as soon as
it is safe to do so, 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.

In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to 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 towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
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. 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.
F

I

f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible. New vehicle
Do not pull a trailer before having driven at
least 600
miles (1,000 kilometres).
For more information on Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
A few seconds after switching off the ignition,
this system locks the engine control system,
therefore preventing the engine from being
started in the event of a break-in.
If the system fails, as reported by a message,
the engine will not start.
Contact a CITROËN dealer.
For safety and theft protection reasons,
never leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with
you.
