Advice

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.

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.

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.

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.

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.
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.

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.

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.

If you are obliged to drive through water:

- 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.

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.

Important!

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.

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 performance. Above
1 000 metres, the maximum towed load must
be reduced by 10 % for every 1 000 metres of
altitude.
For more information on Weights, refer to the
corresponding section.

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

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.

F

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

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.

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.

Anti-theft protection

Electronic engine immobiliser

The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
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.

For reasons of safety and theft protection,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it on
your person.

In the event of a malfunction, you are informed
by a message in the instrument panel screen.

In this case, your vehicle does not start; contact
a CITROËN dealer if required.

Starting / Switching off the engine with the key

It has 3 positions:
- position

1 (Stop)

: insert and removing the

key, steering column locked,

- position

2 (Ignition on)

: steering column

unlocked, ignition on, Diesel preheating,
engine running,

- position

3 (Starting)

.

Ignition switch

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

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.

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.
