FUEL GAUGE
The fuel level is tested each time the key is
turned to the "running" position.
The gauge is positioned on:
- F (Full): the capacity of the fuel tank is
approximately 45 litres .
- E (Empty): the reserve is now being
used, the warning light comes on
continuously.
The reserve when the warning first comes
on is approximately 6 litres.
COOLANT TEMPERATURE

The needle is positioned between
C (Cold) and H (Hot): normal operation.
In arduous conditions of use or hot climatic
conditions, the needle may move close to
the red graduations. - wait approximately 15 minutes to allow
the engine to cool down in order to check
the level and top it up if necessary. The
cooling system is pressurised. In order to
avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, check the
level and remove the cap to top up.
If the needle remains in the red zone,
contact a CITROËN dealer . EMISSION CONTROL
EOBD (European On Board Diagnosis) is
a diagnostics system which complies with,
among others, the standards concerning
authorised emissions of:
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrogen oxides) or particles detected by oxygen sensors placed
upstream and downstream of the catalytic
converters.
Refer to the "Levels" section of
chapter 7. Refer to the "Levels" section of
chapter 7.
Therefore, the driver is warned of
any malfunction of this emission
control system by the flashing of
this specific warning light on the
instrument panel.

What you should do if the needle
enters the red zone, or if the warning
light comes on:
- stop immediately, switch off the ignition. The fan may continue to operate for
a certain time up to approximately
10 minutes.

Gearbox and steering wheel
Stopping - Starting on a slope
This gearbox is a piloted manual gearbox
which does not have a clutch pedal.

Do not use the accelerator pedal to
immobilise the vehicle on a slope, apply
the handbrake instead.
When moving off on a slope, accelerate
gradually while releasing the handbrake.
Switching to sequential mode
Once you have moved off, you can switch to
sequential mode by selecting position M .
Switching to automated mode
After using the sequential mode, you can
return to the automated mode by selecting
position A .
Stopping the vehicle
Before switching off the engine, you can:
- move to position N to leave the gearbox
in neutral,
- leave a gear engaged, such as first or reverse.
In both cases, it is imperative that you apply
the handbrake to immobilise the vehicle.
Reinitialisation
Following disconnection of the battery, the
gearbox must be reinitialised:
- switch on the ignition, "AUTO" appears
on the instrument panel display,
- press the brake pedal,
- wait approximately 30 seconds until "N"
or a gear appears on the instrument
panel display,
- release the brake pedal.
The gearbox is operational again.
Operating anomaly

"AUTO" and the gear engaged
appear on the instrument panel
display.
The gearbox then operates in
auto-active mode, without any action on the
part of the driver.
It continuously selects the gear most suited
to the following parameters:
- driving style,
- road characteristics,
- vehicle load.
To optimise driving comfort and obtain the
most suitable gear, avoid sharp variations in
the pressure on the accelerator pedal.
If you press the accelerator pedal beyond
the point of resistance, the gearbox
selects the gear below to permit sharper
acceleration.

"AUTO" disappears and the
gears engaged appear in
succession on the instrument
panel display.
The gear change requests are only carried
out if the engine speed permits it.
Take your foot off the accelerator pedal
gently to engage the gear.
At low speeds, when approaching a stop
or traffic lights for example, the gearbox
changes down to first gear automatically. With the ignition on, the flashing
of
"AUTO" and lighting of this
warning light, accompanied by
an audible signal and a message
on the instrument panel display, indicate a
gearbox malfunction.
Have it checked by a CITROËN dealer. The brake pedal must be pressed while
starting the engine.
Never select neutral N while the vehicle is
moving.
Only engage reverse gear R with the vehicle
immobilised and the brake pedal pressed.
In all cases, it is imperative that you apply
the handbrake in order to immobilise the
vehicle.
On a steep gradient, it is preferable to
switch to 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 an original CITROËN
towbar is used (see the "Rear parking
assistance" section of chapter 4). Towbar
We recommend the use of original
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, ...).
