Driving
6Before 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.
In all cases, pay 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
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.

cruise control where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Remain vigilant when the cruise control
is activated. If you hold one of the speed
setting modification buttons down, a very
rapid change in the speed of your vehicle may
occur.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the speed of your
vehicle.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed

Blind Spot Monitoring
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system includes sensors, placed on the
sides of the bumpers, and warns the driver of
the potentially dangerous presence of another
vehicle (car, truck, motorcycle) in the blind spot
areas of their vehicle (areas hidden from the driver's field of vision).

The warning is given by a fixed warning lamp
that appears in the door mirror on the side in
question:
– immediately, when being overtaken;– after a delay of about one second, when overtaking a vehicle slowly.
Activation / Deactivation
It is set via the Driving / Vehicle touch
screen menu.
When starting the vehicle, the warning lamp
comes on in each mirror to indicate that the
system is activated.
The state of the system stays in the memory
when switching off the ignition.
The system is automatically deactivated when towing with a towing device
approved by CITROËN.
Conditions for operation
– All vehicles are moving in the same direction and in adjacent lanes.– The speed of your vehicle must be between 7 and 87 mph (12 and 140 km/h).

Driving
6Using 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.
Visual assistance


This supplements the audible signal by
displaying bars on the screen that represent the
distance between the obstacle and the vehicle
(white: more distant, orange: close, red: very
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.
Deactivation / Activation
With / Without audio system


► To deactivate or activate the system, press this button.
The indicator lamp is lit when the system is
deactivated.
