objects in the interior rack.

65
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.

66
Driving
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating of the brakes, the
use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the
wind that the vehicle will have.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic immobiliser
device.
This device locks the engine supply system. It
activates automatically when the key is removed
from the ignition.
When the ignition switch is turned on, a dialogue
is set up between the key and the electronic
immobiliser.
This warning lamp goes off after the key has been recognised, the ignition is
switched on and the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key and
have the faulty key checked by a CITROËN
dealer.
Carefully note the key number. In case of
loss, the intervention of a CITROËN
dealer will be faster and more efficient if you
provide this number and the confidential card.
Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even in your
pocket, may cause the doors to be unlocked
accidentally.
The simultaneous use of other high-frequency
devices (mobile phones, home alarms, etc.),
may temporarily disturb the operation of the
remote control.
Except for reinitialisation, the remote control
cannot operate while the key is in the ignition
switch, even when the ignition is off.
Driving with the doors locked could make
it more difficult for the emergency
services to enter the vehicle in an emergency.
As a safety precaution (with children on
board), remove the key from the ignition when
leaving the vehicle, even for a short time.
When purchasing a second-hand
vehicle:
– check that you are in possession of the
confidential card,
– have the keys memorised by a CITROËN
dealer, to be sure that the keys in your
possession are the only ones that allow the
vehicle to be started.
Confidential card

It is given to you upon delivery of your vehicle
with the duplicate key.
It contains the identification code required for
any intervention by a CITROËN dealer on the
electronic engine immobiliser system. This code
is hidden by a film, which is to be removed only
when necessary.
Keep your card in a safe place, never inside the
vehicle.
When undertaking a long trip or journey
however, it is advisable to take this card with you
along with your personal papers.
Starting-switching off the
engine
Ignition switch

STOP position: Anti-theft.
The ignition is off.
MAR position: ignition on.
Certain accessories can be used.
AV V position: starter.
The starter is operated.
Avoid attaching heavy objects to the key or the remote control, which would weigh
down on its blade in the ignition switch and
could cause a malfunction.

Driving
simultaneously in the two dedicated areas of the
instrument panel.
If an additional road sign is detected, such
as a reduced speed limit for wet road sign, it
is displayed in an empty window below the
corresponding sign.
Additional signs are filtered as follows:
– Signs for snow or ice only appear if the
outside temperature is below 3°C.
– Signs for snow, rain or fog are only displayed
if the wipers are activated while the outside
temperature is below 3°C.
– Signs concerning heavy goods vehicles are
not displayed if they concern a vehicle weighing
less than 4 tonnes.
– Signs concerning farm equipment are not
displayed.
Signs such as no overtaking go out after about
40 seconds on the instrument panel.
Activation/Deactivation
This function can be set using the MODE button: in the “Traffic Sign” menu, select
“ON” or “OFF”.
For more information on Vehicle
configuration (MODE) , refer to the
corresponding section.
Operating limits
The system does not take account of reduced
speed limits, especially those imposed in the
following cases:
– Poor weather (rain, snow).
– Atmospheric pollution.
– Towing.
– Driving with a space-saver type spare wheel
or snow chains fitted.
– Driving with a non-standard suspension kit.
– Tyre repaired using the temporary puncture
repair kit.
– Young drivers.
The system may not display the speed limit if it
does not detect a speed limit sign within a preset
period and in the following situations:
– Road signs that are obstructed, non-standard,
damaged or bent.
– Obsolete or incorrect maps.
– Road incline causing the sign to be out of the
camera field of vision (on a slope, for example).
– Change in the vehicle load that causes the
camera to tilt significantly (system operation may
temporarily be suspended to enable camera
self-calibration).
Speed limiter
Refer to the General recommendations on the
use of driving and manoeuvring aids .
System which prevents the vehicle
from exceeding the speed
programmed by the driver. The speed is selected when the vehicle is
stationary with the engine running or while
driving with at least 2
nd gear engaged.
The minimum speed to be programmed is 19
mph (30 km/h).
The vehicle responds to the driver's foot
pressure on the accelerator until resistance is felt
in the pedal, which signifies that the vehicle has
reached the programmed speed.
However, depressing the pedal beyond this point
of resistance to the floor allows you to exceed
the programmed speed. To resume use of the
speed limiter, gradually release the pressure
on the accelerator pedal and return below the
programmed speed.

contact a CITROËN dealer.
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

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.
