Driving
automatically to preserve the remaining battery
charge.
Switching off the engine leads to a loss
of braking assistance.
Starting the engine
Parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then depress the clutch pedal fully.
► With an automatic gearbox, place the gear
selector in mode N or P then depress the brake
pedal fully.
► 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,
pre-heating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to two minutes (accelerated idle
speed).
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.
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, which 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 the CITROËN dealer.
Starting / Switching off the
engine with the key
Key ignition switch

It has 3 positions:
– position 1 (Stop): inserting and removing the
key, steering column locked.
–
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating, engine
running,
–
position 3 (Starting).
Avoid attaching heavy objects to the key
or the remote control, which would weigh
down on its blade 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

11 4
Driving
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
The Stop & Start system requires a 12 V battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a CITROËN dealer or a
qualified workshop.
Tyre under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Operation
Main conditions for operation
– The driver ’s door must be closed.
– The driver's seat belt must be fastened.
–

The level of charge in the battery must be
sufficient.
–


The temperature of the engine must be within
its nominal operating range.
–


The outside temperature must be between
0°C and 35°C.
Putting the engine into standby
(STOP mode)
The engine automatically enters standby mode
as soon as the driver indicates their intention to
stop.

Driving
6Zoom view

The camera records the vehicle's surroundings
during the manoeuvre in order to create a
view from above the front of the vehicle in its
near surroundings, allowing the vehicle to be
manoeuvred around obstacles nearby.
This view is available with AUTO mode or in the
view selection menu.
Obstacles may appear further away than
they actually are.
It is important to check the sides of the
vehicle during the manoeuvre, using the
mirrors.
The parking sensors also supplement the
information on the vehicle's surroundings.
180° view

The 180° view assists with exiting from a parking
space in forward gear, making it possible to
see the approach of vehicles, pedestrians and
cyclists.
This view is not recommended for carrying out a
complete manoeuvre.
It consists of 3 areas: left A, centre B and right
C.
This view is available only from the view
selection menu.
Park Assist
Refer to the General recommendations on the
use of driving and manoeuvring aids.
This system provides active parking assistance:
it detects a parking space then operates the
steering system to park in this space.
With
manual and automatic gearboxes, the
driver manages the accelerator, brakes and
forward and reverse gear engagement.
During phases of entry into and exit from a
parking space, the system provides visual and
audible information to the driver in order to make
the manoeuvres safe. Several forward and
reverse manoeuvres may be required.
At any time, the driver can take back control by
holding the steering wheel.


The Park Assist system provides assistance for
the following manoeuvres:
A. Entry into a "parallel" parking space
B. Exit from a "parallel" parking space
C. Entry into a "bay" parking space
The Park Assist system cannot operate
with the engine switched off.
When Park Assist is activated, it prevents
Stop & Start from going into STOP mode. In
STOP mode, activation of Park Assist restarts
the engine.
