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 fulfill 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.
Before and after use, ensure that the seat
belt is reeled in correctly.
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.
The inertia reels are fitted with an automatic
locking device which comes into operation 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.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 person.
Never allow a child to travel on your lap.
For more information on Child seats, refer
to the corresponding section.
Advice
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 bear any trace of cuts or fraying,
-

n
ot be converted or modified to avoid
affecting its performance.
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.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
In the event of an impact
Depending on the nature and
seriousness of the impact , the
pretensioning device may be deployed
before and independently of the airbags.
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 belts
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.

Airbags
General information
System designed to contribute towards
improving the safety of the occupants (with
the exception of the rear centre passenger)
in the event of violent collisions. The airbags
supplement the action of the seat belts fitted
with force limiters (all except the centre rear
passenger belt).
If a collision occurs, the electronic detectors
record and analyse the front and side impacts
sustained in the impact detection zones:
-
i
n the case of a serious impact, the airbags
are deployed instantly and contribute
towards better protection of the occupants
of the vehicle (with the exception of the
rear centre passenger); immediately after
the impact, the airbags deflate rapidly so
that they do not hinder visibility or the exit
of the occupants,
-

i
n the case of a minor or rear impact or in
certain roll-over conditions, the airbags
may not be deployed; the seat belt
alone contributes towards ensuring your
protection in these situations. The airbags do not operate when the
ignition is switched off.
This equipment will only deploy once.
If a second impact occurs (during the
same or a subsequent accident), the
airbag will not be deployed again.

individuals may experience slight
irritation.
The noise of detonation associated with
the deployment of one or more airbags
may result in a slight loss of hearing for
a short time.Impact detection zones

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 precaution, the driver must only carry out actions requiring sustained 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 drive with the parking brake
applied - Risk of overheating and
damage to the braking system!
Risk of fire!
As the exhaust system of your vehicle
is very hot, even several minutes
after switching off the engine, do not
park or leave the engine running over
areas where inflammable substances
and materials are present: grass,
leaves,
etc.
Never leave a vehicle unsupervised
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.
Important!
- check 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 system,
-

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.
If you are obliged to drive through water:
On leaving the flooded road, as soon as
circumstances 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.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side 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 towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.
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 Adjusting the
headlamp beam height , refer to the
corresponding section.
For more information on Weights
, 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.
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.

Stop & Start
Operation
Going into engine STOP mode
STOP mode does not affect the
functionality of the vehicle, such as
braking, power steering, for example.
Never refuel with the engine in
STOP mode; you must switch off the
ignition with the key or the "START/
STOP" button.
With a manual gearbox, at a
speed below 12 mph (20 km/h),
If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP STOP mode is not invoked when:
-
t
he vehicle is on a steep slope (up or
d ow n),
-
t
he driver's door is open,
-
t
he driver's seat belt is not fastened,
-
t
he vehicle has not exceeded 6 mph
(10 km/h) since the last engine start (using
the key or the "START/STOP" button),
-
t
he electric parking brake is applied or

This operation is perfectly normal.
With an automatic gearbox,
when
the vehicle is stationary, this warning mode during a journey. It resets itself to zero
every time the ignition is switched on with the
key or the "START/STOP" button.
The Stop & Start

system puts the engine temporarily into standby - STOP mode - during stops in
the traffic (red lights, traffic jams, or other...). The engine restarts automatically - START mode - as
soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as
well as the noise level when stationary.
