Air bags
4
Side air bags
If fi tted on your vehicle, this is a system
which protects the driver and front
passenger in the event of a serious
side impact in order to limit the risk of
injury to the chest.
Each side air bag is incorporated in the
front seat back frame, on the door side. The curtain air bag infl ates between
the front or rear occupant of the vehicle
and the windows.
Impact detection zones

A. Front impact zone.

B. Side impact zone. In the event of a minor impact or
bump on the side of the vehicle or
if the vehicle rolls over, the air bag
may not be triggered.
The air bag is not triggered in the event
of a rear or front collision.
Operating fault
Curtain air bags
If fi tted on your vehicle, this is a
system which protects the driver and
passengers (with the exception of the
centre seats of rows 2 and 3) in the
event of a serious side impact in order
to limit the risk of head injuries.
Each curtain air bag is incorporated
in the pillars and the upper part of the
passenger compartment.
Activation
It is triggered unilaterally in the event
of a serious side impact applied to
all or part of the side impact zone
B ,
perpendicular to the longitudinal
centreline of the vehicle on a horizontal
plane and directed from the outside
towards the inside of the vehicle.
The side air bag infl ates between the
front occupant of the vehicle and the
corresponding door trim pad. Activation
It is triggered at the same time as the
corresponding side air bag in the event
of a serious side impact applied to
all or part of the side impact zone
B ,
perpendicular to the longitudinal
centreline of the vehicle on a horizontal
plane and directed from the outside
towards the inside of the vehicle. If this warning light comes
on on the instrument panel,
accompanied by an audible
signal and a message on the
display, consult a CITROËN
dealer to have the system
checked. The air bags may no longer
be triggered in the event of a serious
impact.

Towing a trailer
On the contrary, use a high gear to
lower the engine speed and reduce
your speed.
In all cases, pay attention to the
coolant temperature.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake
gradually. Please contact a CITROËN dealer fi rst
for further information .
Automatic adjustment
For vehicles with Xenon bulbs, and if
the change in load makes it necessary,
this system automatically corrects the
height of the beam after approximately
2 minutes. The driver is then assured
of having optimum lighting and not
causing a nuisance to other road
users.
In certain cases of particularly
arduous use (towing the
maximum load up a steep slope
in high temperatures), the engine
automatically limits its power. In this
case, cutting off the air conditioning
allows the engine power to be
recovered, and therefore the towing
speed to be signifi cantly increased
(approximately 12 mph [20 km/h]
more). Sequential control of the
gearbox may also become unavailable.
Lighting
Bicycle carrier
Refer to the "Identifi cation
features" section of chapter 8. Refer to the "Steering wheel
controls" section of chapter 3.
When using a trailer connection,
you must add a fuse. Refer to
the "Changing a fuse" section of
chapter 7.

If the coolant temperature warning light
comes on, stop the vehicle and switch
off the engine as soon as possible.

Tyres: check the tyre pressures of
the towing vehicle and of the trailer,
observing the recommended pressure.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
Towbar
We recommend the use of original
CITROËN towbars, which have been
tested for endurance from the design
stage of your vehicle.
Towing equipment must be fi tted in
accordance with the manufacturer’s
instructions, with particular attention to
the towing capacities of your vehicle,
the load towed, the nose weight and
the electrical connection. As this fi tting
should be carried out by a professional,
we recommend that you entrust the
fi tting of this equipment to a CITROËN
dealer.
In accordance with the general
instructions referred to above, we draw
your attention to the risk connected
with fi tting a towbar or other electrical
accessory which is not recommended
by the CITROËN network. Fitting such
equipment could result in a failure of
your vehicle’s electronic system. Manual adjustment
Adjust your headlamps so as not to
dazzle other road users. Check the
electrical signalling of the trailer.
If you fi t a bicycle carrier on
the tailgate, deactivate the
rear wiper from the display's
confi guration menu.

Fuel
LOW FUEL LEVEL
Filling with fuel
The tank must be fi lled with fuel with

the engine off .
- Open the fuel fi ller fl ap.
- Insert the key then turn it to the left.
- Remove the cap and attach it to the clip located on the inside of the
fl ap.
It is usual to hear an air intake noise
when opening the cap as there is a
vacuum linked with the sealing of the
fuel circuit.
A label on the inside of the fl ap
indicates which type of fuel to use.
More than 5 litres of fuel must be
added in order to be registered by the
fuel gauge.
If you fi ll your tank, do not continue
after the third cut-off of the pump
nozzle. This could result in vehicle
malfunctions.
FILLING THE FUEL TANK
If the warning light fl ashes, this
indicates a fuel gauge malfunction.
Consult a CITROËN dealer.
When the tank's minimum
level is reached, this warning
light comes on, accompanied
by the message "Fuel level
low" on the display. When
this warning light fi rst comes on, you
have approximately 8 litres left,
depending on driving conditions and
the engine.
Fill up with fuel as soon as possible to
avoid running out.
Never continue to drive until you run
out of fuel as this could damage the
emission control and injection systems. The capacity of the tank is
approximately 18 gallons (
80 litres).
- After fi lling the tank, lock the cap and close the fl ap. Quality of the fuel used for petrol
engines
The petrol engines are perfectly
compatible with E10 type petrol
biofuels (containing 10 % ethanol),
conforming to European standards
EN 228 and EN 15376.
E85 type fuels (containing up to 85 %
ethanol) are reserved exclusively for
vehicles marketed for the use of this
type of fuel (BioFlex vehicles). The
quality of the ethanol must comply with
European standard EN 15376.
For Brazil only, special vehicles are
marketed to run on fuels containing up
to 100 % ethanol (type E100). When the fuel fi ller fl ap is open, a
system limits the opening of the
rear left sliding side door.
The key cannot be removed from the
cap's lock until the cap is refi tted on the
tank.

120
Levels
Cooling system
Only use the fl uid recommended by
the manufacturer.
Otherwise, you risk seriously damaging
your engine.
When the engine is warm, the
temperature of the coolant is controlled
by the engine fan. As this fan can
operate with the ignition key removed
and because the cooling system is
pressurised, wait for at least one hour
after the engine has stopped before
carrying out any work.
Slacken the cap by 1/4 of a turn to
release the pressure to prevent any
risk of scalding. When the pressure
has dropped, remove the cap and top
up the level with coolant.
If fl uid has to be added frequently,
this indicates a failure which must be
checked by a CITROËN dealer as
soon as possible.
Power steering fluid level
The vehicle must be parked on level
ground with the engine cold. Unscrew
the cap integrated with the gauge and
check the level which must be between
the MIN and MAX marks. During regeneration of the particle
emission fi lter, relay noise may be
heard under the fascia.
If the message is still displayed and
the service warning light remains on,
contact a CITROËN dealer.
Diesel additive level (Diesel with
particle emission filter)
When this occurs with the engine running,
this is due to the start of saturation of
the particle emission fi lter (exceptionally
prolonged urban driving conditions: low
speed, long traffi c jams, ...).
In order to regenerate the fi lter, you
are advised to drive at a speed of
more than 40 mph (60 km/h) as soon
as possible, when traffi c conditions
permit, for at least fi ve minutes (until
the message disappears and the
service warning light is switched off).
Topping up
The level must be between the MIN
and MAX marks on the expansion
bottle. If more than 1 litre of fl uid is
required to top up the level, have the
system checked by a CITROËN dealer.
Windscreen wash and headlamp
wash level
For best quality cleaning and for your
safety, we would advise that you use
products of the CITROËN range.
To avoid ice forming, do not use water.
Topping up
It is imperative that this additive is
topped up by a CITROËN dealer
without delay.
Used oil
Avoid prolonged contact of used oil
with the skin.
Brake fl uid is harmful to health and
very corrosive.
Do not dispose of used oil, brake
fl uid or coolant into drains or onto
the ground but into the containers
dedicated to this use at CITROËN
dealerships.
The minimum level of this
additive is indicated by
lighting of the service warning
light, accompanied by an
audible signal and a message
on the display.
