Driving
6Effective eco-driving saves fuel; accelerate
progressively, anticipate the need to slow down
and adapt your speed to suit the situation.
Indicate changes of direction well in advance so
that you are seen by other road users.
Take care
The tyres must be inflated to at least the
pressures indicated on the label, even over-
inflated by 0.2 to 0.3 bar for long journeys.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
► check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
► deactivate the Stop & Start function,
► drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
► do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the density
of the air decreases with altitude and the
performance of the engine reduces.
New vehicle: do not pull a trailer before
having driven at least 620 miles (1,000
kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill increases the temperature
of the coolant. The maximum towable load
depends on the gradient and the exterior
temperature. The cooling capacity of the fan
does not increase with engine speed.
► Reduce speed and lower the engine speed,
so as to limit the heating-up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.

84
Driving
– Auto: for an automatic detection of the trailer
length (3 m, 6 m or 9 m).
In Auto mode, an icon appears in the instrument
panel indicating the length detected by the
system.
It may be necessary to make a 90° turn
to allow the system to detect the length
of the trailer.
When a trailer is detected, vehicle detection
when reversing is deactivated.
Operating conditions
– All vehicles are moving in the same direction
and in adjacent lanes.
– The speed of your vehicle is 6 mph (10 km/h)
minimum.
– When you overtake a vehicle, the speed
difference is less than 16 mph (25 km/h).
– When another vehicle overtakes you, the
speed difference is less than 31 mph (50 km/h).
Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system:
– warns the driver that their vehicle is at risk of
collision with the vehicle in front.
– reduces the vehicle's speed to avoid a
collision or limit its severity.
This system is comprised of three functions:
– Collision Risk Alert.
– Intelligent emergency braking assistance.
– Active Safety Brake (automatic emergency
braking).


The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
This function can be set using the MODE button; select “ON” or “OFF” in the “Active
Safety Brake” menu.
For more information on Vehicle
configuration (MODE) , please refer to
the corresponding section.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Operating conditions and
limits
The ESC system must not be faulty.
The DSC/ASR systems must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
– towing a trailer,
– carrying long objects on roof bars or roof rack,
– with snow chains fitted,
– before using an automatic car wash, with the
engine running,
– before placing the vehicle on a rolling road in
a workshop,
– towed vehicle, engine running,
– following an impact to the windscreen close to
the detection camera.
It is automatically deactivated after
detection of a fault with the brake pedal
switch or with at least two brake lamps.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of their
vehicle and be prepared to react at any time
to avoid an accident.
Cases of non-detection by the system:
– Pedestrians, cyclists, animals, objects on the
road.
– Vehicles crossing your lane.
– Vehicles driving in the opposite direction.

– When narrow vehicles (motorcycles)
are present and/or there are vehicles
staggered across the traffic lane.
– When entering a tunnel or crossing a
bridge.
When the driver must suspend the system:


– Vehicles in a tight bend.
– When approaching a roundabout.


– When a vehicle cuts in sharply between your
vehicle and the one in front.
Collision Risk Alert
It warns the driver that their vehicle is at risk of
collision with the vehicle in front.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the vehicle configuration menu.
► Select one of the three pre-defined
thresholds:
– "Near ".
– "Normal".
– "Distant".
The last threshold selected is memorised 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, several different levels
of alert may be triggered and displayed in the
instrument panel.
They take account of the vehicle dynamics, the
speed of your vehicle and the one in front, the
environmental conditions and the operation of
the vehicle (cornering, actions on the pedals,
etc.) to trigger the alert at the best moment.
Level 1 (orange): visual alert only,
signalling that the vehicle in front is very
close.

towbar-mounted carrier, the towball must be
removed and the protective plug inserted in the
carrier. This measure applies particularly where
the towball might obscure visibility of the number
plate or its lighting.
wheels, check that no part of the chain or its
fixings is in contact with the wheel rim.
Towing a trailer

The type-approved towable weights are entered
in your vehicle's registration certificate, as well
as on the manufacturer's plate.
For more information on the Technical
characteristics of the vehicle and
particularly on weights and towable loads,
refer to the corresponding section.
You will then have information on your vehicle's
ability to tow a trailer, a caravan, a boat, etc.
These values are also given in the sales
brochures.
We recommend using genuine CITROËN
towbars and their harnesses that have
been tested and approved from the design
stage of your vehicle, and having a CITROËN
dealer fit the towbar.
These genuine towbars are compatible with
the operation of the rear parking sensors and

on version).
For more information on
the Identification markings of the
vehicle, and in particular the tyre pressure
label, refer to the corresponding section.
Changing a bulb
The headlamps have polycarbonate lenses with a protective coating:
► do not clean them using a dry or
abrasive cloth, nor with a detergent or
solvent product,
► use a sponge and soapy water or a pH
neutral product,
► when using a high pressure washer on
persistent marks, do not keep the lance
directed towards the lamps or their edges for
too long, so as not to damage their protective
coating and seals.
Changing a bulb must only be done with
the ignition off and after the lamp has
been switched off for several minutes - Risk
of serious burns!
► Do not touch the bulb directly with your
fingers, use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
with the same type and specification.
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal surface of the glass
of the headlamps and rear lamps is normal; it

122
In the event of a breakdown
► Connect the red cable to metallic terminal A,
then to the (+) terminal of backup battery B.
► Connect one end of the green or black cable
to the negative (-) terminal of backup battery B.
► Connect the other end of the green or black
cable to earth point C of your vehicle.
► Operate the starter, let the engine run.
► Wait for the engine to return to idle and
disconnect the cables.
Charging the battery using a
battery charger
► Access the battery, located in the left-hand
front floor.
► Disconnect the battery.
► Follow the instructions for use provided by
the manufacturer of the charger.
► Reconnect starting with the (-) terminal.
► Check the cleanliness of the terminals. If they
are covered with sulphate (whitish or greenish
deposit), remove and clean them.
The charging operation must be carried out in a well-ventilated area and away
from naked flames and any sources of sparks
so as to avoid the risk of explosion or fire.
Do not try to recharge a frozen battery: it
must first be thawed to avoid the risk of
explosion. If it has frozen, before charging it,
have the battery checked by a specialist who
will check that the interior components have
not been damaged and that the container is
not cracked, which would involve a risk of
leakage of toxic and corrosive acid.
Perform a slow charge at low amperage for
about 24 hours maximum to avoid damaging
the battery.
The presence of this label, in particular with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification; the
involvement of a CITROËN dealer or a
qualified workshop is essential when
replacing or disconnecting the battery.
After refitting the battery at a CITROËN dealer or a qualified workshop, the Stop
& Start system will only be active after a
continuous period of immobilisation of the
vehicle, a period which depends on the
climatic conditions and the state of charge of
the battery (up to about 8 hours).
