or has not been properly
released.
Mechanical brake to hold the vehicle
when stationary.
“CVT” GEARBOX
The six-speed automatic gearbox
offers a choice between the comfort of
automatic regulation or the pleasure of
manual gear changing.
This gearbox enables you to access
two driving modes:
- an automated mode for automatic control of the gears by the gearbox
and therefore without any action on
the part of the driver,
- a sequential mode for manual changing of the gears by the driver
using the steering wheel controls or
the gear lever.
It consists of the following controls:
- a gear lever 1 on the centre console
for selecting the driving mode, re-
verse gear and neutral or for chang-
ing gear in sequential mode,

When starting 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 +/-.

“D” disappears and the gears engaged
appear in succession on the instrument
panel display.
The gear change requests are only car-
ried out if the engine speed permits it.

Switching to automated mode
Automated mode
After using the sequential mode, you
can return to the automated mode by
selecting position D .

“D” appears on the instrument panel
display.
The gearbox then operates in auto-ac-
tive 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 var-
iations in the pressure on the accelera-
tor pedal. “Auto sequential” mode
In the automated mode, you can
resume control temporarily at any time
using the steering wheel controls.
The use of these controls permits man-
ual selection of the gears in situations
which require a faster changedown
than that offered in automated mode
(arrival at a roundabout, exit from a car
park with a steep gradient, overtaking,
etc.).
The gearbox engages the gear re-
quested if the engine speed permits it.
The gear engaged appears.
To return to the automated mode, press
the back of the
“+/OFF” control for ap-
proximately 2 seconds.
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 fi rst or reverse.
In both cases, it is imperative that you
apply the handbrake to immobilise the
vehicle. Operating anomaly
With the ignition on, if the message

“Slow down” or
“Maintenance
required” appears on the multifunction
display, this indicates a gearbox mal-
function.
When a message is displayed, carry
out the following operations:
- slow down and stop your vehicle in a safe place,
- place the lever in position N and let
the engine run,
- open the bonnet to allow the engine to cool.
If the message disappears for a long
period, you can set off again.
If the message remains displayed or
appears frequently, contact a CITROËN
dealer without delay.
Take your foot off the accelerator pedal
gently to engage the gear.
At low speeds, when approaching a
stop or traffi c lights for example, the
gearbox changes down to fi rst gear au-
tomatically.

Operating faults
If the selected transmission mode
display fl ashes, the vehicle switches
automatically to front “2WD”

transmission mode.
It is then no longer possible to select the
transmission mode using the control A . Do not subject the vehicle to
excessive conditions while driving.
As the engine torque is applied to
all four wheels, the condition of the
tyres has a considerable impact on
the performance of the vehicle.
Ensure that all four tyres are in good
condition.
Avoid driving the vehicle in sandy
or muddy areas or in other areas in
which the wheels could spin.
Spinning the wheels places the
transmission components under
pressure and could cause a serious
malfunction.
Do not drive the vehicle through
deep water.
Avoid driving over excessively
uneven terrain (risk of scraping
under the body or of grounding on
crossing a bridge).
Have your vehicle towed on
a fl atbed.
The vehicle must not be towed
with the front or rear wheels on the
ground even if it is in front “2WD”
(2 wheel drive) mode.
If the message “SLOW DOWN” is
displayed on the instrument panel, let
the transmission cool down then wait
for the display to clear before setting off
again.
If “4WD” and “LOCK” are displayed al-
ternately and if “MAINTENANCE RE-
QUIRED” is displayed on the instru-
ment panel, the system has failed and
the safety system has been activated.
Contact a CITROËN dealer without
delay.

CHECKING LEVELS Brake fluid level To avoid any risk of scalding, unscrew
the cap by two turns to allow the
pressure to drop. When the pressure
has dropped, remove the cap and top
up the level.
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 15 minutes.
The check is carried out either when
the ignition is switched on using the oil
level indicator on the instrument panel,
or using the dipstick.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (1,000 km). The brake fl uid level should be
between the “MAX” and “MIN”
marks.
If it is not, check the brake pad
wear.
Draining the circuit
Refer to the servicing booklet for details
of the interval for this operation.
Coolant level
The coolant level must be
measured when the engine is
cold and should be between
the “LOW” and “FULL” marks.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the ig-
nition off.

On vehicles which are fi tted with a
particle emission fi lter, the fan may
operate after the vehicle has been
switched off, even if the engine is
cold.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work. Wash-wipe and headlamp

while the engine is running.
Do not charge the batteries
without disconnecting the
terminals fi rst. Following reconnection of the
battery
Following reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to permit initialisation of
the electronic systems. However, if slight
diffi culties are encountered following this
operation, contact a CITROËN dealer.
Referring to the corresponding section,
you must yourself reinitialise:
- the one-touch electric windows,
- the sunroof,
- the satellite navigation system.
Avoid prolonged contact of the
electrolyte with the skin.
Most of these fl uids are harmful
to health and very corrosive. It is advisable to disconnect the
battery if the vehicle is to be left
unused for more than one month.
The batteries contain harmful
substances such as sulphuric acid
and lead. They must be disposed of
in accordance with regulations and
must not, in any circumstances, be
discarded with household waste.
Take used remote control batteries
and vehicle batteries to a special
collection point.
When charging the battery, it is
normal to observe an increase in
temperature and bubbling of the
electrolyte.

TOWING A TRAILER,
CARAVAN, ETC.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving advice
The maximum towing load on a long
slope depends on the gradient and the
outside temperature.
In all cases, pay attention to the coolant
temperature.
Side wind

 Take into account the increased
sensitivity to side wind.
Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.

 To lower the engine speed, reduce
your speed. Braking
Towing a trailer increases the braking
distance.
Tyres

 Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.
Lights

 Check the electrical signalling on
the trailer.

If this message is
displayed, stop your
vehicle as soon as it
is safe to do so.
If the message fl ashes
slowly, wait for the engine to cool before
topping up the level, if necessary.
If the message fl ashes rapidly, contact
a CITROËN dealer without delay.
Opening of the lower tailgate
is prohibited if a towbar is
being used.
Driving with a trailer subjects the towing
vehicle to more signifi cant stress and
its driver must be particularly careful.
We recommend the use of
original CITROËN towbars
and their harnesses that have
been tested and approved from the
design stage of your vehicle and that
the fi tting of the towbar is entrusted
to a CITROËN dealer.
If the towbar is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted using the electrical pre-
equipment located at the rear of the
vehicle and in accordance with the
manufacturer’s instructions.
Towbar suited to the attachment of
a trailer or caravan with additional
signalling and lighting.
Distribution of loads

 Distribute the load in the trailer so
that the heaviest items are as close
as possible to the axle and the nose
weight approaches the maximum
permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towing
load must be reduced by 10 % of the
GTW and so on for every 1 000 metres
of altitude.
Refer to the “Technical Data” section for
details of the weights and towing loads
which apply to your vehicle.
