In emergency braking, press the brake
pedal hard and maintain this pressure.
After an impact, have these systems
checked by a CITROËN dealer or
a


qualified workshop.
Anti-slip regulation (ASR)/
Dynamic stability control
(DSC)
Operation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of
a problem with grip or trajectory.
Deactivation of the ASR
In exceptional conditions (starting a vehicle
w hich is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip. F

I
n the Driving
menu, select the " Driving
functions " tab, then " Traction control".
Deactivation is confirmed by the display of
a

message.
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.
Reactivation of the ASR
The system is reactivated automatically every
time the ignition is switched back on or from
31
mph (50 km/h).
Below 31
mph (50 km/h), you can reactivate it
manually:
F

I
n the Driving menu, select the " Driving
functions " tab, then " Traction control".
Operating fault
The illumination of this warning
lamp, accompanied by an audible
signal and a
message, indicates that
there is a
fault with these systems. 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 observation of the
manufacturer's recommendations, not
only about the wheels (tyres and rims),
braking and electronic components but
also 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.
This is indicated by flashing of this
warning lamp in the instrument
panel. Reactivate the system when grip conditions
allow.
Contact a
CITROËN dealer or a qualified
workshop to have the systems checked.

Safety

108
At a speed above 12 mph (20 km/h), these
w arning lamps flash, associated with an
audible signal, for two minutes. Beyond this
period of time, the warning lamps stay on
continuously until the seat belts are fastened.
Rear seat belts not fastened alert
When the ignition is switched on, with the
engine running or the vehicle moving above
6
mph (10 km/h), warning lamp A and the
corresponding dots in warning lamp B come on
for around thirty seconds, if one or more rear
passengers have not fastened their seat belts.
Seat belts unfastened alert
After the ignition is switched on, warning lamp
A and the corresponding dots in warning lamp
B come on if the driver and/or one or more
passengers unfasten their seat belts.
These warning lamps flash for 30
seconds,
accompanied by an audible signal. Beyond
this period of time, the warning lamps stay on
continuously until the seat belts are fastened.
Advice
The driver must ensure that passengers
use the seat belts correctly and that they
are all fastened before setting off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for
short journeys.
Do not interchange the seat belt buckles
as they will not fulfil their role fully.
The seat belts are fitted with an inertia
reel permitting automatic adjustment of
the length of the strap to your size. The
seat belt is stowed automatically when not
in use.
The inertia reels have an automatic
locking device at the time of a
collision,
during sudden braking or if the vehicle
turns over. You can release the device by
pulling the strap firmly and then releasing
it so that it reels in slightly.
Before and after use, ensure that the seat
belt is reeled in correctly.
After folding or moving a
seat or rear
bench seat, ensure that the seat belt is
positioned and reeled in correctly. Installation
The lower part of the strap must be
positioned as low as possible on the
pelvis.
The upper part must be positioned in the
hollow of the shoulder.
In order to be effective, a seat belt must:
-

b
e tightened as close to the body as
possible,
-

b
e pulled in front of you with a smooth
movement, checking that it does not
twist,
-

b
e used to restrain only one person,
-

n
ot show any signs of cuts or fraying,
-

n
ot be converted or modified to avoid
affecting its performance.
Recommendations for children
Use a
suitable child seat if the passenger
is less than 12
years old or shorter than
one and a
half metres.
Never use the same seat belt to secure
more than one child.
Never allow a
child to travel on your lap.
For more information on Child seats ,
refer to the corresponding section.

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. 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.

In case of towing
Driving with a trailer places greater
d emands 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
t emperature 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.
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
approximately 620


miles (1,000

kilometres).
Braking
Towing a trailer increases the braking distance.
T o 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
adjustment , refer to the corresponding
section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system 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.
This electronic engine immobiliser locks the
engine management system a
few moments
after the ignition is switched off, and prevents
starting of the engine by anyone who does not
have the key.
In the event of a
malfunction, you are informed
by a
message in the instrument panel screen.
If this happens, your vehicle will not start;
contact a
CITROËN dealer if required.
