Observe the recommendations
on maintenance
Check the tyre pressures regularly, when cold,
referring to the label in the door aperture,
driver's side.
Carry out this check in particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Do not forget the spare wheel and the tyres on
any trailer or caravan. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations in the
manufacturer's service schedule.
With a
BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. Visit a CITROËN dealer or
a qualified workshop as soon as possible to
bring your vehicle's nitrogen oxide emissions
back in line with the regulations.
When filling the tank, do not continue after the
3rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after the first 1,900
miles (3,000 kilometres)
that you will see the fuel consumption settle
down to a
consistent average.
At the end of winter, remove snow tyres and
refit your summer tyres. Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer, etc.). Preferably, use a
roof box.
Remove roof bars and roof racks after use.

Ensure that you are steady on your feet
before making the kicking movement
below the rear bumper.
Take care not to touch the exhaust
system, which may be hot – Risk of burns!
"Hands-free " closing
F If your hands are full, with the remote
control on you in the recognition zone A ,
make a
kicking movement with your foot
below the rear bumper.
Flashing of the direction indicator lamps and
a


beeping sound confirm the request.
Making another kicking movement with your
foot below the bumper while the tailgate is
closing interrupts the movement. A third kicking
movement reverses the direction of movement.
Deactivation
By default, hands-free access is activated.
This function can be activated or deactivated
by selecting " Hands-Free Tailgate Access " in
the Driving menu of the touch screen.
Automatic locking
To lock the vehicle when the tailgate closes
using a kicking movement, activate " Hands-
free tailgate access self-locking " in the
Driving menu of the touch screen.
Recommendations related
to the Hands-Free Tailgate
Access function

In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
t emperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a trailer before having driven at least
approximately 620


miles (1,000

kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
adjustment , refer to the corresponding
section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
This electronic engine immobiliser locks the
engine management system a
few moments
after the ignition is switched off, and prevents
starting of the engine by anyone who does not
have the key.
In the event of a
malfunction, you are informed
by a
message in the instrument panel screen.
If this happens, your vehicle will not start;
contact a
CITROËN dealer if required.

Collision Risk Alert
It warns the driver if their vehicle is at risk of
collision with the vehicle in front or a pedestrian
present in their traffic lane.
Modifying the alert trigger
threshold
This threshold determines how you wish
to be alerted of the presence of a moving
or stationary vehicle in front of you, or
a
pedestrian present in your traffic lane.
The current threshold can only be
modified via the touch screen's
Driving menu.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of
alert can be triggered and displayed in the
instrument panel.
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
conceal the detection camera.
Clean the front bumper, especially around
the radar, removing mud, snow, etc.

Blind Spot Detection
This system warns the driver of the presence
of another vehicle in the blind spots of their
vehicle (areas hidden from the driver's field
of vision), as soon as this presents a potential
danger.
A fixed warning lamp appears in the door mirror
on the side in question:
-
i

mmediately, when being overtaken,
-

a
fter a delay of about one second, when
overtaking a
vehicle slowly. This driving aid system is designed to
improve safety when driving and is in no
circumstances a
substitute for the use
of the interior rear view mirror and door
mirrors. It is the driver's responsibility to
constantly check the traffic, to assess the
relative distances and speeds of other
vehicles and to predict their movements
before deciding whether to change lane.
This system is a driving aid that cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
Activation/Deactivation
The function is activated and
deactivated in the Driving menu of
the touch screen.
When the function is activated,
this indicator lamp comes on in the
instrument panel.
The state of the system stays in memory when
switching off the ignition.
The system is automatically deactivated
when towing with a
towing device
approved by CITROËN.
Operation
Sensors fitted in the front and rear bumpers
monitor the blind spots.
The alert is given by an orange warning lamp
coming on in the relevant door mirror, as soon
as a
vehicle – car, lorry, cycle – is detected.
The following conditions must be met for this:
-

a
ll vehicles are moving in the same direction
and in adjacent lanes,
-

t
he speed of the vehicle must be between
7
and 87 mph (12 and 140 km/h),
-

-

t
he traffic is flowing normally,
-

ov
ertaking a vehicle over a certain period
of time and the vehicle being overtaken
remains in the blind spot,
-

y
ou are driving on a straight or slightly
curved road,
-

y
our vehicle is not pulling a trailer, a
caravan, etc.
