Special position of the
windscreen wipers
This maintenance position is used while cleaning
or replacing the wiper blades. It can also be
useful, in winter (ice, snow), to release the wiper
blades from the windscreen.
To maintain the effectiveness of the flat wiper blades, it is advisable to:
– handle them with care.– clean them regularly using soapy water .– avoid using them to hold cardboard on the windscreen.– replace them at the first signs of wear.

Safety
5All terrain (mud, damp grass, etc.)
This mode, when moving off, allows considerable spin on the wheel with the
least grip to optimise clearing of the mud and to
regain grip. At the same time, the wheel with the
most grip is controlled in such a way as to
transmit as much torque as possible.
When moving, the system optimises wheel spin
to respond to the driver's requirements as fully
as possible.
(mode active up to 31 mph (50 km/h))
Sand
This mode allows little spin on the two driving wheels at the same time to allow
the vehicle to move forward and limit the risks of
getting stuck in the sand.
(mode active up to 75 mph (120 km/h))
Do not use the other modes on sand as
the vehicle may become stuck.
You can deactivate the ASR and DSC systems by turning the knob to the "OFF "
position.
The ASR and DSC systems will no longer act on the operation of the engine
or of the brakes in the event of a change of
trajectory.
These systems are reactivated automatically
from 31 mph (50 km/h) and whenever the ignition is switched on.
Recommendations
The vehicle is designed principally to
drive on tarmac roads, but it allows you to
occasionally drive on other less passable
terrain.
However, it does not permit off-road driving
such as:
– driving on terrain which could damage the underbody or strip away components (fuel
pipe, fuel cooler, etc.) due to obstacles or
stones in particular,
– driving on terrain with steep gradients and poor grip,– crossing a waterway .
Hill Assist Descent
System that provides assistance when
descending on loose or soft surfaces (gravel,
mud, etc.) or a steep gradient.
This system reduces the risk of slip or loss of
control of the vehicle when descending, whether
going forward or in reverse.
During a descent, it assists the driver in
maintaining a constant speed, depending on the
gear engaged, while progressively releasing the
brakes.
For the system to activate, the slope
must be greater than 5%.
The system can be used with the gearbox in
neutral.
Otherwise engage a gear corresponding to
the speed to prevent the engine stalling.
With an automatic gearbox, the system can
be used with the selector at N, D or R.
When the system is regulating, the Active
Safety Brake system is automatically
deactivated.
Operation
Switching on
By default, the system is not selected.
The state of the function is not saved when the
ignition is switched off.
The driver can select the system when the
engine is running, when the vehicle is stationary
or when moving at speeds up to approximately
31 mph (50 km/h).

Foot on the brake
► Depress the brake pedal when this warning lamp is displayed on the
instrument panel (e.g. when starting the engine).
Starting the vehicle
► With your foot on the brake pedal, select position P or N.► Start the engine.If the conditions are not met, you will hear an
audible signal, accompanied by the display of a
message.
► With the engine running, press the brake pedal.
► Release the parking brake, unless it is programmed to automatic mode.► Select position R, D or M.► Gradually release the brake pedal.The vehicle moves off immediately.
If position N is selected inadvertently
while driving, allow the engine to return
to idle, then select position D to accelerate.
When the engine is running at idle with
the brakes released, if position R, D or M
is selected, the vehicle moves even without
the accelerator being pressed.
Never leave children unattended in the
vehicle when the engine is running.
When carrying out maintenance with the
engine running, apply the parking brake and
select position P.
Automatic operation
► Select position D for automatic changing of
the six gears.
The gearbox then operates in auto-adaptive
mode, without any intervention on the part of the
driver. It continuously selects the most suitable
gear according to the driving style, the road
profile and the load in the vehicle.
For maximum acceleration without touching the
selector, press the accelerator fully down (kick-
down). The gearbox changes down automatically
or holds the gear selected until the maximum
engine speed is reached.
When braking, the gearbox changes down
automatically to provide effective engine braking.
If you release the accelerator sharply, the
gearbox will not shift to a higher gear for safety
reasons.
Never select position N while the vehicle
is moving.
Never select positions P or R unless the
vehicle is completely stationary.
"Sport" and "Snow" programmes
These two special programmes supplement the
automatic operation in specific conditions of use.
"Sport"
► Press this button, once the engine has started.
"S" appears on the instrument panel.
The gearbox automatically favours a dynamic
style of driving.
"Snow"
► Press this button, once the engine has started.
"T" appears on the instrument panel.
The gearbox adapts to driving on slippery roads.
This programme improves starting and traction
when grip is poor.
Return to automatic operation
► At any time, press the selected button ("S or
"T") again to quit the activated programme and
return to auto-adaptive mode.
Manual operation
To limit fuel consumption during an extended standstill with the engine
running (for example, in a traffic jam), set the
gear selector to N and apply the parking
brake.
► Selecting position M enables sequential
shifting between the six gears.
► Push backwards to shift up a gear .

94
Driving
► Push forwards to shift down a gear.The gearbox only changes gear if the road
speed and engine speed permit; apart from
this condition, the rules for automatic operation
temporarily apply.
D disappears, and the gears engaged appear in
succession on the instrument panel.
If the engine speed is too low or too high, the
selected gear flashes for a few seconds, then the
gearactually activated is displayed.
It is possible to change from position D to
position M
at any time.When the vehicle is stationary or moving
very slowly, the gearbox selects gear M1
automatically.
The Sport and Snow programmes are inactive
in manual operation.
This symbol is displayed if a gear is not engaged correctly (gear selector between
two positions).
Switching off the vehicle
Before switching off the engine, it is possible to
engage position P or N to place the gearbox in
neutral.
In both cases, apply the parking brake to
immobilise the vehicle.
If the gear selector is not in position P,
when the driver's door is opened or
approximately 45 seconds after the ignition is
switched off, an audible signal sounds and a
message appears.
► Return the gear selector to P; the audible
signal stops and the message disappears.
Malfunction
In the event of a malfunction, this warning lamp comes on and a message is
displayed, when the ignition is switched on.
In this case, the gearbox goes into back-up
mode and is locked in 3
rd gear. It is possible to
feel a significant jolt (without risk for the gearbox)
while changing from P to R and from N to R.Do not exceed 62 mph (100 km/h), local speed restrictions permitting.
Have it checked by a CITROËN dealer or a
qualified workshop.
There is a risk of damaging the gearbox:– If the accelerator and brake pedals are pressed simultaneously.– In the event of a battery failure, forcing the selector from position P to another position.
With an automatic gearbox, never try to
start the engine by pushing the vehicle.
Gear efficiency indicator
(Depending on engine.)
This system helps reduce fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and the
vehicle's equipment, the system may advise to
skip one or more gears.
Gear shift recommendations should not be
considered compulsory. In fact, the road layout,
the traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued by
the system.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual operation.
The information appears in the instrument panel, in the form of an arrow and the
recommended gear.
The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (power, acceleration, braking,
etc.).
The system never suggests:
– engaging first gear;– engaging reverse.
Hill start assist
This system keeps your vehicle briefly stationary (for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake pedal to the accelerator pedal.
This system is only active when:
– The vehicle is completely stationary, with your foot on the brake pedal.– Certain slope conditions are met.– The driver’s door is closed.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If someone needs to get out of the vehicle
with the engine running, apply the parking
brake manually. Then check that the parking
brake indicator lamp is on fixed in the
instrument panel.
The hill start assist function cannot be deactivated. However, use of the parking
brake to immobilise the vehicle interrupts its
operation.

Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
- START mode - as soon as the driver wishes to
move off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and

The engine automatically enters standby mode
as soon as the driver indicates their intention to
stop.
– With a manual gearbox: with the gear lever in
neutral and the clutch pedal released.
– With an automatic gearbox: with the gear
selector in position D or M, the brake pedal
depressed until the vehicle stops or the gear
selector in position N, with the vehicle stationary.
Time counter
A time counter adds up the time spent in standby
during the journey. It is reset to zero every time
the ignition is switched on.
Special cases:
The engine will not go into standby if all of the
conditions for operation are not met and in the
following cases.
– Steep slope (ascending or descending).– Vehicle has not exceeded 6 mph (10 km/h) since the last engine start (with the key or the
“START/STOP” button).
– Needed to maintain a comfortable temperature in the passenger compartment.– Demisting active.– Braking assistance being used.In these cases, this indicator lamp flashes for a few seconds, then goes off.
After the engine has restarted, STOP
mode is not available until the vehicle
has reached a speed of 5 mph (8 km/h).
During parking manoeuvres, STOP mode
is not available for a few seconds after
coming out of reverse gear or turning the
steering wheel.
Engine restarting (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again.
► With a manual gearbox : with the clutch
pedal fully depressed.
► With an automatic gearbox :• With the selector in position D or M: with the
brake pedal released.
• With the selector in position N and the brake

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.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
– worsens road-holding.– lengthens braking distances.
– causes premature wear of the tyres.– increases fuel consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
► Reduce speed immediately , avoid excessive steering movements and avoid sudden braking.► Stop the vehicle as soon as it is safe to do so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.
► Using a compressor , such as the one in the temporary puncture repair kit, check the
pressures of the four tyres when cold.
► If it is not possible to make this check immediately, drive carefully at reduced speed.

Coffee Break Alert
The system triggers an alert as soon as it detects that the driver has not taken a
break after two hours of driving at a speed above
40 mph (65 km/h).This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
– With the engine running, the vehicle has been stationary for more than 15 minutes.– The ignition has been switched off for a few minutes.– The driver's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops below 40 mph (65 km/h), the system goes into standby.
The driving time is counted again once the
speed is above 40 mph (65 km/h).
Driver Attention Warning
Depending on version, the "Coffee Break Alert"
system is combined with the "Driver Attention
Warning" system.


Using a camera placed at the top of the windscreen, the system assesses the
driver's level of vigilance, fatigue or distraction by
identifying variations in trajectory compared to
the lane markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65 km/h)).At a first-level alert, the driver is warned by the
“Take care! ” message, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere with the operation of the system or
prevent it from working:
– lane markings absent, worn, hidden (snow , mud) or multiple (roadworks);– close to the vehicle ahead (lane markings not detected);– roads that are narrow, winding, etc.
Lane Departure Warning
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
This system, using a camera which recognises
solid or broken lines, detects the involuntary
crossing of longitudinal traffic lane markings on
the ground.
If the driver's attention drops and the speed
is higher than 37 mph (60 km/h), the system triggers a warning if there is an unexpected
change of direction.
This system is particularly useful on motorways
and main roads.


Deactivation / Activation
The system is activated every time the ignition
is switched on.


OFF

► To deactivate the system, press this button.Deactivation is signalled by the lighting
of the indicator lamp on the button and
this warning lamp on the instrument panel.
Reactivation is carried out via another press; the
indicator lamp on the button and the warning
lamp go out.
Detection
If an unexpected change of direction is detected, this warning lamp flashes in the
instrument panel accompanied by an audible
signal.
No warning is transmitted while the direction
indicator is activated and for approximately 20
