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 both the wheels (tyres and
rims), braking and electronic components
and the assembly and repair procedures
used by CITROËN dealers.
The use of snow tyres is recommended,
in order to be able to benefit from the
efficiency of these systems in winter
conditions.
In this case, it is essential to equip the
four wheels with tyres approved for your
vehicle.Trailer stability assist (TSA)
When towing, this system reduces the risk of
the vehicle or trailer swaying.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control (ESC) must not
have any faults.
If the system detects oscillations (snaking) in
the movement of the trailer at speeds between
37 and 99 mph (60 and 160 km/h), it acts
on the brakes to stabilise the trailer and, if
necessary, reduces the engine power to slow
down the vehicle.
The correction is signalled by the
flashing of this warning lamp in the
instrument panel and illumination of
the brake lamps.
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
To w b a r d e v i c e , refer to the corresponding
section.
Operating fault
Should a fault occur with the system,
t his 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,
provided that the recommendations on
towing a
trailer are obser ved. It should not
encourage the driver to take 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 drive at too high a
speed.
In certain cases, snaking 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 snaking of the trailer.
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.

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 equipped with an
inertia reel which allows the strap length
to automatically adjust to your shape.
The seat belt returns to its storage
automatically when it is not used.
The inertia reels are fitted with a device
which automatically locks the strap in the
event of a
collision, emergency braking or
if the vehicle rolls 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 in order
not to affect its per formance.
Recommendations for children
Use a
child seat appropriate to the child's
age, weight and size.
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. Servicing
In accordance with current safety
regulations, for all repairs on your
vehicle's seat belts, go to a
qualified
workshop with the skills and equipment
needed, which a
CITROËN dealer is able
to provide.
Have your seat belts checked regularly
by a
CITROËN dealer or a qualified
workshop, particularly if the straps show
signs of damage.
Clean the seat belt straps with soapy
water or a
textile cleaning product, sold by
CITROËN dealers.
In the event of an impact
Depending on the nature and seriousness
of the impacts, the pyrotechnic device
may trigger before and independently of
airbag deployment. Deployment of the
pretensioners is accompanied by a
slight
discharge of harmless smoke and a
noise,
due to the activation of the pyrotechnic
cartridge incorporated in the system.
In all cases, the airbag warning lamp
comes on.
Following an impact, have the seat belt
system checked, and, if necessary,
replaced, by 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.
Respect the maximum towable weights.
At altitude: reduce the maximum load
by 10% per 1,000
metres of altitude; the
decreased air density at altitude reduces
engine performance.
New vehicle: do not pull a
trailer
before having driven at least 620
miles
(1,000


kilometres). If the outside temperature is high, let the
engine idle for 1
to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
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 about the state of your vehicle,
contact a
CITROËN dealer or a qualified
workshop.
F

D
istribute the load in the trailer so that the
heaviest items are as close as possible to
the axle and the nose weight (at the point
where it joins your vehicle) approaches the
maximum permitted without exceeding it.
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 signalling on the trailer and the headlamp beam height of your
vehicle.
If a
genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the
audible signal.
When driving
Cooling
Towing a trailer uphill increases the
t emperature of the coolant. The maximum
towable load depends on the gradient and the
exterior temperature. The cooling capacity of
the fan does not increase with engine speed.

educe speed and lower the engine speed,
so as to limit the heating-up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as
soon as possible.
Brakes
Braking distances are increased when towing
a trailer. To avoid overheating of the brakes, the
use of engine braking is recommended.

Active Safety Brake
Operation
- The vehicle's speed does not exceed 50 mph (80 km/h) when a stationary vehicle
or a
cyclist is detected.
-

T
he vehicle's speed is above 6 mph
(10
km/h) (versions with camera and radar)
or between 6
mph and 53 mph (10 km/h and
85
km/h) (versions with camera alone) when
a
moving vehicle is detected.If the camera and/or radar have
confirmed the presence of a
vehicle,
a pedestrian or a
cyclist, this

10
seconds) when the function is
acting on the vehicle's brakes.
With an automatic gearbox, in the event of
automatic emergency braking until the vehicle
comes to a
complete stop, keep the brake
pedal pressed down to prevent the vehicle from
starting off again.
With a
manual gearbox, in the event of
automatic emergency braking until the vehicle
comes to a
complete stop, the engine may stall.
The driver can control the vehicle at any
time by making a
deliberate movement
of the steering wheel and/or pressing the
accelerator pedal. Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a
complete stop,
the automatic braking is maintained for
1
to 2 seconds.
Malfunction

Active Lane Departure
Warning System
Refer to the General recommendations on
the use of driving and manoeuvring aids .Using a
camera located at the top of the
windscreen to identify lane markings on the
road and at the edges of the road (depending
on version), the system corrects the trajectory
of the vehicle while alerting the driver if it
detects a risk of unintentionally crossing a line
or hard shoulder (depending on version).
This system is particularly useful on motor ways
and main roads.
Conditions for operation
The speed of the vehicle must be between
40 and 112 mph (65 and 180 km/h).
The driver must hold the wheel with both
hands.
The change of trajectory must not be
accompanied by operation of the direction
indicators.
The ESC system must not be faulty.
The ASR /DSC systems must be activated.
The system helps the driver only when
there is a
risk of the vehicle involuntarily
wandering from the lane it is being driven
in. It does not manage the safe driving
distance, the speed of the vehicle or the
brakes.
Operation
Once the system identifies a risk of the vehicle
i nvoluntarily crossing one of the lane markings
detected, it makes the correction to the
trajectory required to return the vehicle to its
initial path.
The driver will notice a
turning movement of the
steering wheel.
This warning lamp flashes during
trajectory correction.
The driver can prevent the correction by
keeping a
firm grip on the wheel (during
an avoiding manoeuvre, for example).
The correction is interrupted if the
direction indicators are operated.
If the system detects that the driver is not
holding the wheel firmly enough during
an automatic correction of trajectory,
it interrupts the correction. An alert is
triggered to encourage the driver to take
back control of the vehicle.
