only be made when the vehicle is
stationary.
Before taking to the road and to make the most
of the ergonomic layout of the instruments and
controls, carry out these adjustments in the
following order:
– head restraint height.– seat backrest angle.– seat cushion height.– longitudinal seat position.– steering wheel height and reach.– rear view mirror and door mirrors.

Once these adjustments have been
made, check that the instrument panel
can be viewed correctly from your driving
position.

Mirrors
Door mirrors

Demisting - Defrosting
Demisting-defrosting of the door mirrors operates with the engine running, by
switching on the heated rear screen.
For more information on Demisting - defrosting
the rear screen , refer to the corresponding
section.
Adjustment

► Move control A or turn control C (depending
on the version you have) to the right or to the left
to select the corresponding mirror.
► Move control B or C (depending on the
version you have) in any of the four directions to
adjust.
► Return control A or C (depending on the
version you have) to its centre position.
As a safety measure, the mirrors should be adjusted to reduce the "blind spots".
The objects observed are, in reality, closer
than they appear.
Take this into account in order to correctly
judge the distance of vehicles approaching
from behind.
Manual folding
You can manually fold the mirrors (parking
obstruction, narrow garage, etc.)

Lighting and visibility
4• If the "AUTO" and "Main beam" indicator lamps were on, the system changes to dipped beam.
To reactivate the system, flash the headlamps
again.
The system may be disrupted or not work correctly:
– When visibility conditions are poor (snowfall, heavy rain, etc.).– If the windscreen in front of the camera is dirty, misted or obscured (for example, by a
sticker).
– If the vehicle is facing highly reflective signs.
When the system detects thick fog, it
temporarily deactivates the function.
The system is not able to detect:
– Road users that do not have their own lighting, such as pedestrians.– Vehicles whose lighting is obscured (for example, vehicles driving behind a safety
barrier on a motorway).
– Vehicles at the top or bottom of a steep slope, on winding roads, on crossroads.
Clean the windscreen regularly,
particularly the area in front of the
camera.
The internal surface of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
obstruct the detection camera.
Headlamp beam height
adjustment



To avoid causing a nuisance to other road users,
the height of the headlamp beams should be
adjusted according to the load in the vehicle.
0. (Initial adjustment)
Driver only or driver + front passenger
1. Driver + front passenger + rear passengers +
maximum authorised load
2. Driver only + maximum authorised load
Cornering lighting

If your vehicle is so equipped, this system
makes use of the beam from a front foglamp to
illuminate the inside of a bend, when the main or
dipped beam headlamps are on and the vehicle
speed is below 25 mph (40 km/h) (urban driving,
winding road, intersections, parking manoeuvres,
etc.).

Driving
Driving recommendations
► Observe the driving regulations and remain vigilant whatever the traffic conditions.► Monitor your environment and keep your hands on the wheel to be able to react to
anything that may happen any time.
► Drive smoothly, anticipate the need for braking and maintain a longer safety distance,
especially in bad weather.
► Stop the vehicle to carry out operations that require close attention (such as adjustments).► During long trips, take a break every two hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In severe wintry conditions (temperature
below -23°C), let the engine run for 4
minutes before moving off, to ensure the
correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damage to the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (dry grass, dead leaves, etc.). The
exhaust system of your vehicle is very hot,
even several minutes after the engine stops.
Risk of fire!
Never leave a vehicle unattended 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).
Never leave children inside the vehicle
unsupervised.
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 on a flooded road:
► 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 function,► 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 safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the density
of the air decreases with altitude and the
performance of the engine reduces.
New vehicle: do not pull a trailer before
having 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 heating up.
