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.

If this warning lamp and the STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, whose secret code must be
recognised in order for starting to be possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a CITROËN dealer.
For safety and theft protection reasons,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with you.
Starting / Switching off the
engine with the key
Key ignition switch

It has 3 positions:– 1. Stop : inserting and removing the key,
steering column locked.
– 2. Ignition : steering column unlocked, ignition
on, Diesel preheating, engine running.
– 3. Starting.
Avoid attaching heavy objects to the key or the remote control. It would weigh
down on its shaft in the ignition switch and
could cause a malfunction.
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

Driving
– When overtaking a vehicle, the speed difference is less than 6 mph (10 km/h).– When overtaken by a vehicle, the speed difference is less than 16 mph (25 km/h).– Traffic is flowing normally.– Overtaking a vehicle over a certain period of time and the vehicle being overtaken remains in
the blind spot.
– You are driving on a straight or slightly curved road.– Your vehicle is not pulling a trailer, a caravan, etc.
Operating limits



No alert is triggered in the following conditions:– In the presence of non-moving objects (parked vehicles, barriers, street lamps, road signs, etc.).– Oncoming traffic.– Driving on a winding road or a sharp corner .– When overtaking or being overtaken by a very long vehicle (lorry, bus, etc.) that is detected
in the rear blind spot but is also present in the
driver’s front field of vision.
– When overtaking quickly.– In very heavy traffic: vehicles detected in front and behind are confused with a lorry or a
stationary object.
Malfunction
In the event of a malfunction, this warning lamp flashes for a few
moments in the instrument panel, accompanied
by the Service warning lamp coming on and the
display of a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The system may suffer temporary interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet surface or
moving from a dry area to a wet area can
cause false alerts (for example, the presence
of a fog of water droplets in the blind spot
angle is interpreted as a vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in
the door mirrors or the detection zones on the
front and rear bumpers with adhesive labels
or other objects; they may hamper correct
operation of the system.
Parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .


Using sensors located in the bumper, this system signals the proximity of obstacles (e.g. pedestrian, vehicle, tree, barrier) present in their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear, which is confirmed by an audible signal.
The system is switched off when disengaging
reverse gear.
Audible assistance

The system signals the presence of obstacles
within the sensors’ detection zone.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.

close).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
In addition to the rear parking sensors, the front
parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle
is still below 6 mph (10 km/h).
The front parking sensors are interrupted if the
vehicle stops for more than three seconds in
forward gear, if no further obstacles are detected
or when the speed of the vehicle exceeds 6 mph
(10 km/h).
The sound emitted by the speaker (front or rear) indicates whether the obstacle is
in front or behind.

Top Rear Vision
Refer to the General recommendations on the
use of driving and manoeuvring aids .


As soon as reverse gear is engaged with the
engine running, this system displays views of
your vehicle’s close surroundings on the touch screen using a camera located at the rear of the
vehicle.



The screen is divided into two parts with a
contextual view and a view from above the
vehicle in its close surroundings.
The parking sensors supplement the information
on the view from above the vehicle.
Various contextual views may be displayed:
– Standard view
.
– 180° view.– Zoom view .AUTO mode is activated by default.
In this mode, the system chooses to display the
best view (standard or zoom).
You can change the type of view at any time
during a manoeuvre.
The state of the function is not saved when the
ignition is switched off.
Principle of operation

Using the rear camera, the vehicle's close
surroundings are recorded during manoeuvres
at low speed.
An image from above your vehicle in its close
surroundings is reconstructed (represented
between the brackets) in real time and as the
manoeuvre progresses.
It facilitates the alignment of your vehicle when
parking and allows obstacles close to the vehicle
to be seen. It is automatically deleted if the
vehicle remains stationary for too long.
Rear vision

To activate the camera, located on the tailgate,
engage reverse and keep the speed of the
vehicle below 6 mph (10 km/h).The system is deactivated:– Automatically, at speeds above approximately 6 mph (10 km/h),– Automatically, if the tailgate is opened.– Upon changing out of reverse gear (the image remains displayed for 7 seconds).– By pressing the white arrow in the upper-left corner of the touch screen.
