Advice

The incorrect installation of a child seat in a
vehicle compromises the child's protection
in the event of an accident.
Ensure that there is no seat belt or seat belt
buckle under the child seat, as this could
destabilise it.
Remember to fasten the seat belts or the
child seat harnesses keeping the slack
relative to the child's body to a minimum,
even for short journeys.
When installing a child seat using the seat
belt, ensure that the seat belt is tightened
correctly on the child seat and that it
secures the child seat firmly on the seat
of your vehicle. If your passenger seat is
adjustable, move it forwards if necessary.

For optimum installation of the forward
facing child seat, ensure that the back of
the child seat is as close as possible to the
backrest of the vehicle's seat, in contact if
possible.
You must remove the head restraint before
installing a child seat with backrest to a
passenger seat.
Ensure that the head restraint is stored or
attached securely to prevent it from being
thrown around the vehicle in the event of
sharp braking. Refit the head restraint when
the child seat is removed.

As a safety precaution, do not leave:
- a child or children alone and

unsupervised in a vehicle,

- a child or an animal in a vehicle which

is exposed to the sun, with the windows
closed,

- the keys within reach of children inside

the vehicle.

To prevent accidental opening of the doors
and rear windows, use the child lock.
Take care not to open the rear windows by
more than one third.
To protect young children from the rays of
the sun, fit side blinds on the rear windows.

At rear seating positions, always leave
sufficient space between the front seat and:
- a rearward facing child seat,
- the child's feet for a child seat fitted

forward facing.

To do this, move the front seat forwards
and, if necessary, move its backrest into the
upright position.

Children at the front

The legislation on carrying children on the
front passenger seat is specific to each
country. Refer to the legislation in force in
your country.
Deactivate the passenger's front airbag
when a rearward facing child seat is
installed on the front passenger seat.
Otherwise, the child risks being seriously
injured or killed if the airbag is deployed.

Installing a booster seat

The chest part of the seat belt must be
positioned on the child's shoulder without
touching the neck.
Ensure that the lap part of the seat belt
passes correctly over the child's thighs.
CITROËN recommends the use of a
booster seat which has a back, fitted with a
seat belt guide at shoulder level.

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,

- deactivate the Stop & Start system,
- drive as slowly as possible without

stalling. In all cases, do not exceed 6 mph
(10 km/h),

- do 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

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 performance. Above
1 000 metres, the maximum towed load must
be reduced by 10 % for every 1 000 metres of
altitude.

Side wind

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

To 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.

If 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.

Tyres

Check the tyre pressures of the towing

vehicle and of the trailer, observing the
recommended pressures.

Lighting

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.

186

Driving

Avoid attaching heavy objects to the
key or the remote control, which would
weigh down on its blade in the ignition
switch and could cause a malfunction.
It could adversely affect the
deployment of the front airbag.

Starting / Switching off the engine with the key

It has 3 positions:
- position

1 (Stop)

: insert and removing the

key, steering column locked,

- position

: steering column

unlocked, ignition on, Diesel preheating,
engine running,

- position

3 (Starting)

Ignition switch

Ignition on position

It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops
to the reserve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preserve the remaining
battery charge.

Switching off the engine leads to a loss
of braking assistance.

Anti-theft protection

Electronic engine immobiliser

In the event of a fault, you are
informed by illumination of this
warning lamp, an audible signal
and/or the display of a message,
depending on version.

Keep safely, away from your vehicle,
the label attached to the keys given to
you on acquisition of the vehicle.

In this case, your vehicle will not start; contact
a CITROËN dealer as soon as possible.

The keys contain an electronic chip which has
a special code. When the ignition is switched
on, this code must be recognised for engine
starting to be authorised.
This electronic engine immobiliser locks the
engine management system a few minutes
after the ignition is switched off and prevents
starting of the engine by anyone who does not
have the key.

In wintry conditions, the warning lamp
can stay on for a longer period. When
the engine is hot, the warning lamp
does not come on.

In certain cases, you may have to apply
more force to the steering (wheels on
full lock, for example).

If the engine does not start straight
away, switch off the ignition. Wait a
few moments before operating the
starter motor again. If the engine does
not start after several attempts, do not
keep trying: you risk damaging the
