automatically and gradually switch between day
and night usage.
To ensure optimum visibility while manoeuvring, the mirror automatically
brightens when reverse gear is engaged.

Automatic illumination of
lamps
With the lighting control stalk in the “ AUTO”
position and if a low level of exterior brightness
is detected by the rain/sunshine sensor, the
sidelamps and dipped beam headlamps are
switched on automatically, without any action on
the part of the driver. They may also come on if
rain is detected, at the same time as automatic
operation of the windscreen wipers.
As soon as the brightness returns to a sufficient
level or after the windscreen wipers are switched
off, the lamps are switched off automatically.
Malfunction
In the event of a malfunction of the rain/
sunshine sensor, the vehicle’s lamps
come on and this warning lamp is displayed on
the instrument panel, accompanied by an
audible signal and/or the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
Do not cover the rain/sunshine sensor
located at the top centre of the

mirror; the associated functions would no
longer be controlled.
In fog or snow, the rain/sunshine sensor
may detect sufficient light. For this
reason, the lighting will not come on
automatically.
The inner surface of the windscreen may become misted up and affect the proper
operation of the rain/sunshine sensor.
In humid and cold weather, demist the
windscreen regularly.

Safety
5Lateral airbags
Use only approved seat covers
compatible with the deployment of these
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
CITROËN dealer.
Do not fix or attach anything to the seat
backrests (e.g.
clothing) as this could cause
injuries to the chest or arm when the airbag is
deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof.
Active bonnet
(Depending on version.)

The active bonnet has been designed to
optimise the safety of pedestrians in the event of
collision with the front of the vehicle.
The pyrotechnic system is triggered at the
hinges of the bonnet to lift it, when the sensors
located at the front of the vehicle detect a
collision.
Deployment of the active bonnet is
accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system. The airbag
warning lamp comes on.
After triggering, do not try to open or close
the bonnet. Call a towing company or go to
the nearest CITROËN dealer or qualified
workshop, driving at a speed below 19 mph
(30

km/h).
Make sure that you adjust the height of the
driver's seat - risk of hindrance to visibility!
This equipment will only trigger once. If a second impact occurs (during the same
or a subsequent accident), the active bonnet
will not trigger.
After an accident or if the vehicle has been
stolen, have the system checked.
Do not tamper with the pyrotechnic systems
under the bonnet, close to the struts - risk of
explosion!
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and
an audible signal. You must contact a CITROËN
dealer or a qualified workshop to have the
system checked.
The active bonnet may not deploy in the event of
an impact.

secured to them.
–

One ring
B, located behind the seat, called the
TOP TETHER, for attaching seats fitted with an
upper strap.


This system prevents the child seat from tipping
forwards in the event of a front impact.
This ISOFIX mounting system provides fast,
reliable and safe fitting of the child seat in the
vehicle.
To secure the child seat to the TOP TETHER:
►

Remove and stow the head restraint before
installing the child seat on this seat (refit it once
the child seat has been removed).
► Pass the strap of the child seat behind the
seat backrest, centring it between the openings
for the head restraint rods.
►

Secure the upper strap hook to ring

.
►

T
ighten the upper strap.
When fitting an ISOFIX child seat to the
left-hand rear seat of the bench seat,
before fitting the seat, first move the centre
rear seat belt towards the middle of the
vehicle, so as to avoid the seat interfering
with the operation of the seat belt.
An incorrectly installed child seat in a vehicle compromises the child's safety in
the event of an accident.
Strictly observe the fitting instructions
provided in the user guide supplied with the
child seat.
For information about the options for
fitting ISOFIX child seats in your vehicle,
refer to the summary table.
Recommended ISOFIX child seats

Driving
6Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has 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
► Distribute 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.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► 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 causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
►


Pay constant 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
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a CITROËN dealer.
Starting/Switching off the
engine with Keyless Entry
and Starting
The electronic key must be present in the passenger compartment.
If the electronic key is not detected, a
message is displayed.
Move the electronic key so that the engine
can be started or switched off.
