Driving
Failure to follow this advice could cause
permanent damage to the gearbox
(inadvertent engagement of 3
rd or 4th gear).
Engaging reverse gear

► Raise the ring under the knob and move the gear lever to the left then forwards.
Only engage reverse gear when the
vehicle is stationary with the engine at
idle.
As a safety precaution and to facilitate starting the engine:
– always select neutral,– press the clutch pedal.
* Snow programme : depending on the country of sale.
Automatic gearbox (EAT6)
6-speed automatic gearbox which offers a choice
between the comfort of automatic operation or
manual gear changing.
Two driving modes are available:
– Automatic operation for electronic
management of the gears by the gearbox:
• With the Sport programme for a more
dynamic driving style.
• Or the Snow programme to improve driving
in the event of poor grip. *
– Manual operation for sequential changing of
the gears by the driver.
In automatic mode, you can still change gear
manually using the steering mounted control
paddles (e.g. to overtake).

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.

automatic gearbox.


Facing downhill, with the vehicle stationary
and reverse gear engaged, the vehicle is held
for a short time when you release the brake
pedal.
Malfunction
This warning lamp comes on in the event of a malfunction, accompanied by an onscreen message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
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
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.

Operation
Main conditions for operation
– The driver ’s door must be closed.– The driver's seat belt must be fastened.– The state of charge of 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.
– 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
pedal released: with the selector at D or M.
• With the selector in position P and the brake
pedal depressed: with the selector at R, N,
D or M.
• Reverse gear engaged.
Special cases
The engine will restart automatically if all
conditions for operation are met again and in the
following cases.
– Vehicle speed exceeds 2 mph (3 km/h).– Some specific conditions (braking assistance, air conditioning setting, etc.).In these cases, this indicator lamp flashes for a few seconds, then goes off.
Malfunctions
In the event of a malfunction, the button’s
indicator lamp flashes briefly, then remains on.
Have the vehicle checked by a CITROËN dealer
or a qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
► Switch off the ignition then start the engine again with the key or the " START/STOP" button.
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.

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.

Cruise control - particular
recommendations
For the safety of everyone, only use the
cruise control where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Remain vigilant when the cruise control
is activated. If you hold one of the speed
setting modification buttons down, a very
rapid change in the speed of your vehicle may
occur.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the speed of your
vehicle.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
programmed speed flashes).
To return to the speed setting, release the
accelerator pedal (when the set speed is
reached again, the displayed speed stops
flashing).
Operating limits
Never use the system in the following
situations:
– In an urban area with the risk of pedestrians crossing the road.– In heavy traffic.– On winding or steep roads.– On slippery or flooded roads.– In poor weather conditions.– Driving on a speed circuit.– Driving on a rolling road.– When using snow chains, non-slip covers or studded tyres.
Cruise control
Refer to the General recommendations on the
use of driving and manoeuvring aids and to
Cruise control - particular recommendations.
This system automatically keeps the vehicle’s speed at the cruise value
programmed by the driver (speed setting), without using the accelerator pedal.
The cruise control is switched on manually.
It requires a minimum vehicle speed of 25 mph
(40 km/h).With a manual gearbox, third gear or higher must
be engaged.
With an automatic gearbox, mode D or second gear or higher in mode M must be engaged.
