Gearbox and steering wheel
Stopping - Starting on a gradient
This is an electronic gearbox system without
a clutch pedal.
To immobilise the vehicle on a gradient,
you must use the parking brake and not
the accelerator.
When starting on a gradient, accelerate
gradually while releasing the parking brake.
Changing to sequential mode
Once you have started the engine, you
can go into sequential mode by selecting
position M.
Changing to automatic mode
When in sequential mode, you can return to
automatic mode by selecting position A.
Stopping the vehicle
Before switching off the engine, you can:
- select position N to engage neutral.
- leave a gear engaged, such as first or
reverse gear.
In either case, you must engage the parking
brake to immobilise the vehicle.
Reinitialising
Following a battery disconnection, you must
reinitialise the gearbox:
- switch on the ignition, "AUTO" appears
on the instrument panel display,
- press on the brake pedal,
- wait for about 30 seconds until "N" or
a gear appears on the instrument panel
display,
- release the brake pedal.
The gearbox is now operational again.
Operating anomaly
"AUTO" is displayed and the
gear selected appears on the
instrument panel display.
The gearbox operates in
automatic mode, without the need for driver
intervention.
It always selects the gear best suited to the
following parameters:
- driving style,
- road profile,
- vehicle load.
To maximise driving comfort and obtain the
most suitable gear, avoid making rough
movements on the accelerator pedal.
If you press the accelerator beyond the point
of resistance, the gearbox selects the next
gear down to allow for faster acceleration.
"AUTO" disappears and
the gears selected appear
successively on the instrument
panel display.
Gear change requests are only possible if
the engine speed allows them.
Gently lift your foot from the accelerator
pedal to select the gear.
When driving at low speed (e.g. approaching
a stop sign or at traffic lights), the gearbox
automatically changes down to first gear.
With the ignition switched on, the
fl ashing of "AUTO" and the lighting
of this warning lamp, accompanied
by a sound signal and a message on
the instrument panel display, indicate a gearbox
malfunction.
Have the system checked by your CITROËN dealer.
You must always press the brake pedal down when starting the engine. When the vehicle is moving, never select neutral N.Only select reverse gear R with the vehicle stationary and your foot on the brake pedal.In all cases, you must engage the parking brake to immobilise the vehicle.When on a steep gradient, you are advised to use sequential mode.

Towing a trailer
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning light comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.
Tyres: check the tyre pressures of the
towing vehicle (see the "Identification
features" section of chapter 7) and of
the trailer, observing the recommended
pressure.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
ABS: the system only controls the vehicle,
not the trailer.
Rear parking assistance:
the assistance will be deactivated
automatically when a CITROËN towbar is
used (see the "Rear parking assistance"
section of chapter 4).
Towbar
We recommend the use of CITROËN
towbars and their harnesses, which have
been tested and approved from the design
stage of your vehicle, and that the fitting of
this equipment is entrusted to a CITROËN
dealer .
If this equipment is not fitted by a CITROËN
dealer , it is essential that it is fitted using
the electrical pre-equipment located at the
rear of the vehicle in accordance with the
manufacturer ’s instructions.
The operation of the sensors is deactivated
automatically when the pin of the trailer
cable is inserted in the towbar socket.
When the trailer cable pin is removed, the
sensors are re-activated.
Distribution of loads
Distribute the load in the trailer so that the
heaviest objects are as close as possible
to the axle and the nose weight is close to
the maximum authorised without, however,
exceeding it. The air density decreases with
altitude, so reducing the performance of
the engine. The maximum towed load must
be reduced by 10 % for each 1 000 metres
of altitude. Refer to the "Technical data"
chapter for details of the weights and towed
loads applicable to your vehicle and also to
the administrative documents
(V5 registration document, etc.).
