Advice
Remote control
The remote control is a sensitive, high-
frequency device; avoid handling it in your
pocket, due to the risk of unintentionally
unlocking the vehicle.
Avoid pressing the remote control buttons
while out of range of the vehicle, due to
the risk of rendering the remote control
inoperative. It would then be necessary to
reset it.
The remote control does not work
when the
key is in the ignition switch, even when the
ignition is switched off.
Anti-theft protection
Do not modify the electronic vehicle
immobiliser, as this might result in
malfunctions.
For vehicles with a key ignition switch,
remember to remove the key and turn the
steering wheel to engage the steering lock.
Locking the vehicle
Driving with the doors locked could make
it more difficult for the emergency services
to enter the passenger compartment in an
emergency.
As a safety precaution, remove the key from
the ignition or take the electronic key with you
when leaving the vehicle, even for a short
time.
Purchasing a second-hand vehicle
Have the key codes memorised by a
CITROËN dealer, to ensure that the keys in
your possession are the only ones able to
start the vehicle.
Keyless Entry and Start

and starting of the vehicle, while carrying the

6Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has 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 the amount of heating produced.
►


Pay constant 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
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
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,
never leave the electronic key in the
vehicle, even when you are close to it.
