Electronic stability control
(ESC)
The electronic stability control programme includes the following systems:
– Anti-lock braking system (ABS) and Electronic brake force distribution (EBFD).– Emergency braking assistance (EBA).– Anti-slip regulation (ASR).– Dynamic stability control (DSC).
Anti-lock braking system
(ABS) and Electronic brake
force distribution (EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
EBFD manages the braking pressure wheel by
wheel.
This warning lamp comes on fixed in the event of an ABS malfunction.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
This warning lamp, when lit together with the STOP and ABS warning lamps,
accompanied by a message and an audible
signal, indicates an EBFD malfunction.

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.

the vehicle is held for a short time when you
release the brake pedal:
– provided you are in first gear or neutral with a manual gearbox.– provided you are in mode D or M with an
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.
With / Without audio system


► Press the button.A message in the instrument panel confirms the
change of status.
When the function is deactivated, the orange
indicator lamp is lit; if the engine was in standby,
it restarts immediately.

Driving
6• 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.

The only fuel additives authorised for use are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the formation of paraffins in summer-type Diesel fuels could prevent the engine from operating
correctly. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50 % full.At temperatures below -15 °C (+5 °F) to avoid problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity: approximately 45 litres.
Reserve level: approximately 5 litres.
Low fuel level
/2
1 1When the low fuel level is reached, one of these warning lamps comes
on on the instrument panel, accompanied by an
onscreen message and an audible signal. When
it first comes on, about 5 litres of fuel remain.
Until sufficient fuel is added, this warning lamp
appears every time the ignition is switched on,
accompanied by an onscreen message and
an audible signal. When driving, this message
and audible signal are repeated with increasing
frequency as the fuel level drops towards 0.
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of fuel
(Diesel), refer to the corresponding section.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Additions of fuel must be of at least 5 litres, in
order to be registered by the fuel gauge.
Opening the filler cap may create a noise caused
by an inrush of air. This vacuum is entirely
normal, resulting from the sealing of the fuel
system.
To refuel in complete safety:
► You must switch off the engine.

124
Practical information
► With the vehicle unlocked, press the rear-central part of the filler flap to open it.► Take care to select the pump that delivers the correct fuel type for the vehicle's engine (see a
reminder label on the inside of the filler flap).
► Turn the filler cap to the left.

► Remove the filler cap and hang it on its carrier (on the filler flap).► Introduce the filler nozzle and push it in as far as possible before starting to refuel (risk of
blowback).
► Fill the tank.Do not continue past the third cut-off of the
nozzle, as this may cause malfunctions.
► Refit the filler cap.► Turn it to the right.► Push the filler flap to close it.
If you have put in the wrong fuel for the
vehicle, you must have the fuel tank
drained and filled with the correct fuel before
starting the engine. The vehicle is fitted with a catalytic converter, a
device which helps to reduce the level of harmful
emissions in the exhaust gases.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, admitting unleaded
petrol nozzles only.
Fuel cut-off
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.
Misfuel prevention (Diesel)
(Depending on country of sale.)
This mechanical device prevents filling the tank
of a Diesel vehicle with petrol.
Located in the filler neck, the misfuel prevention
device is visible when the filler cap is removed.
Operation

When a petrol filler nozzle is inserted into the
fuel filler neck of a Diesel vehicle, it comes into
contact with the flap. The system remains closed
and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
It remains possible to use a fuel jerrycan
to fill the tank.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Before travelling abroad, it is advisable to
check with a CITROËN dealer if the vehicle is
suitable for the distribution equipment of the
countries visited.
Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the vehicle
when braking.
The snow chains must be fitted only to the front wheels. They must never be
fitted to "space-saver" type spare wheels.
Take account of the legislation specific to each country on the use of snow chains
and the maximum authorised speed.
Use only the chains designed to be fitted to the type of wheel fitted to the vehicle:
Original tyre size Chain types
195/65 R15
Maximum 9 mm link
195/60 R16
205/60 R16 Cannot be fitted with
chains
215/50 R17
For more information on snow chains, contact a
CITROËN dealer or a qualified workshop.
Installation tips
► To fit the chains during a journey, stop the vehicle on a flat surface on the side of the road.► Apply the parking brake and position any wheel chocks under the wheels to prevent
movement of the vehicle.
► Fit the chains following the instructions provided by the manufacturer.► Move off gently and drive for a few moments, without exceeding 31 mph (50 km/h).► Stop the vehicle and check that the snow chains are correctly tightened.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry surface.
Avoid driving with snow chains on roads that have been cleared of snow to avoid
damaging the vehicle's tyres and the road
