Driving
automatically to preserve the remaining battery
charge.
Starting the engine
With the parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then fully depress the clutch pedal.
► With an automatic gearbox, place the gear
selector in mode N or P then fully depress the
brake pedal.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
preheating the catalytic converter can
cause noticeable engine vibrations for
anything up to 2 minutes while stationary with
the engine running (accelerated idle speed).
► With a Diesel engine, turn the key to position
2, ignition on, to operate the engine preheating
system.
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 increases the temperature
of the coolant. The maximum towable load
depends on the gradient and the exterior
temperature. The cooling capacity of the fan
does not increase with engine speed.
►

Reduce speed and lower the engine speed,
so as to limit the 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 of the brakes, the
use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the
wind that the vehicle will have.
Anti-theft protection
Electronic immobiliser
The key contains an electronic chip which has a
special code. When the ignition is switched on,
this code must be recognised in order for starting
to be possible.
This electronic engine immobiliser locks the
engine management system a moment after
the ignition is switched off, and prevents
unauthorised engine starting.
In the event of a fault, you are informed
by illumination of this warning lamp, an
audible signal and a message in the screen.
In this case, your vehicle will not start; contact
a CITROËN dealer or a qualified workshop as
soon as possible.
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

Practical information
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
► Grasp the dipstick by its coloured grip and
pull it out completely.
► Wipe the end of the dipstick using a clean,
lint-free cloth.


► Unclip the stay from its housing and place it
in the support slot to hold the bonnet open.
Closing
► Hold the bonnet and pull out the stay from the
support slot.
►

Clip the stay in its housing.
►


Lower the bonnet and release it near the end
of its travel.
►


Pull on the bonnet to check that it is locked
correctly

.
Because of the presence of electrical
equipment under the bonnet, it is strongly
recommended that exposure to water (rain,
washing, etc.) be limited.

only by a CITROËN dealer or a qualified
workshop.
Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluids must comply with the manufacturer's requirements and with
the vehicle's engine.
Take care when working under the bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.

qualified workshop.
–

below mark B

: top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for the engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your CITROËN dealer and
qualified workshops).
Use of non-recommended oil may invalidate
the contractual warranty in the event of
engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding under-bonnet engine
compartment illustration.
►

Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
► Wait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
Within 30 minutes of adding oil, the oil
level indication in the instrument panel
when the ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the brake
pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the
"MAX" mark but should never exceed it.
