Driving
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.
Starting/Switching off the
engine with Keyless Entry
and Starting
The electronic key must be present in the passenger compartment.
If the electronic key is not detected, a
message is displayed.
Move the electronic key so that the engine
can be started or switched off.

90
Driving
For versions fitted with Proximity Keyless
Entry and Start, the electronic key is also
detected in the boot.
If there is still a problem, refer to the "Key
not detected - Back-up starting or Back-up
switch-off" section.
Starting
► Select mode P or N on the automatic
gearbox, then depress the brake pedal.


► Press the " START/STOP" button while
maintaining pressure on the pedal until the
engine starts.
In all circumstances, if one of the starting
conditions is not met, a message is displayed.
In some circumstances, a message indicates
that it is necessary to turn the steering wheel
while pressing the " START/STOP" button to
assist unlocking of the steering column.
Petrol engines
With Petrol engines, after a cold start,
pre-heating the catalytic converter can cause
noticeable engine vibrations, for anything up
to 2 minutes (accelerated idle speed).
Starting rechargeable hybrid
vehicles
► Fully depress the brake pedal and press
the START/STOP button for approximately 2
seconds.
► Keep you r foot on the pedal until this
indicator lamp comes on, indicating the
activation of the rechargeable hybrid system
(confirmed by an audible signal).
To exit Park mode, wait for the READY indicator lamp to come on.
By default, the system starts in Electric mode.
Depending on certain parameters (battery
charge level or outside temperature), the system
determines whether it is necessary to start the
petrol engine.
It is possible to change the driving mode at any
time using the mode selector.
When the vehicle starts in electric mode,
it makes no noise.
Pay particular attention to pedestrians and
cyclists who may not hear the vehicle coming
despite the pedestrian horn.
Switching off
► Deactivate cruise control alone or Highway
Driver Assist (depending on version).
►

Immobilise the vehicle using the parking
brake.
►


Select mode
P on the automatic gearbox.
► Press the "START/STOP" button.
► For rechargeable hybrid vehicles, before
leaving the vehicle, check that the READY

indicator lamp is switched off.
The automatic gearbox locks in mode P.
If the vehicle is not immobilised, the
engine will not stop.
With the engine off, the braking and
steering assistance systems are also cut
off - risk of loss of control of the vehicle!
Never leave your vehicle with the
electronic key still inside.
Switching on the ignition
without starting the engine
With the electronic key in the passenger
compartment, pressing the " START/STOP"
button, without depressing any of the pedals ,
allows the ignition to be switched on without
starting the engine.
►

Press this button again to switch off the
ignition and allow the vehicle to be locked.

Back-up starting
A back-up reader is fitted to the steering column,
to enable the engine to be started if the system

Practical information
7pressures cause tyres to wear prematurely
and have an adverse effect on the vehicle's
road holding - risk of accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the
tyres (tread and sidewalls) and rims as well as
the presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
CITROËN dealer or a qualified workshop.
Timing and accessory kits
The timing and accessory kits are used
from the time the engine is started until it
is switched off. It is normal for them to wear over
time.
A
faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
Free-wheeling
In certain situations, it is necessary to put the
vehicle in neutral (e.g. towing, on a rolling road,
automatic car wash (Wash mode), rail or sea
transport).
Never leave the vehicle unattended with
the vehicle into free-wheeling mode.
Keyless Entry and Starting
You must not depress the brake pedal
while switching the ignition on again, then
switching it off. If you do, the engine will start,
requiring you to restart the procedure.
/
Release procedure
► With the vehicle stationary and the engine
running, depress the brake pedal and select
mode
N.
Within 5
seconds:
►

Depress and hold the brake pedal, then
observe this order: switch off the engine and
move the push selector forwards or backwards.
►


Release the brake pedal, then switch on the
ignition.
►


Place your foot on the brake and press the
electric parking brake control to release it.
►


Release the brake pedal, then switch off the
ignition.
A message is displayed on the instrument panel to confirm the unlocking
of the wheels for 15 minutes.
When the vehicle is free-wheeling, the
audio system cannot be updated (message
displayed on the instrument panel).
After 15 minutes or to revert to normal
operation
► While depressing the brake pedal, restart the
engine and select mode P
