Safety
5Standard (ESC)
This mode is calibrated for a low level of wheel spin, based on the different levels
of grip normally encountered on the road.
Whenever the ignition is switched off, the
system automatically resets to this mode.
Snow
This mode adapts its strategy to the conditions of grip encountered for each of
the two front wheels on moving off.
(mode active up to 50 mph (80
km/h))
All 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
Control
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.
The system is not available: – if the speed of the vehicle is above 43
mph (70
km/h),
–

if the speed of the vehicle is being
controlled by the

Adaptive Cruise Control,
depending on the type of gearbox.

82
Safety
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiter
This system reduces the pressure of the seat
belt on the chest of the occupant, thus improving
their protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. Deployment of the
pretensioners is accompanied by a slight
discharge of harmless smoke and a noise,
due to the activation of the pyrotechnic
cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
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).




With instrument panels with dials► To select the system, at speeds below
31 mph (50 km/h), press this button until
its indicator lights up; this lamp appears in green
in the instrument panel.
The system becomes active at speeds below 19
mph (30
km/h).
With digital instrument panel
► To select the system, at speeds below
31 mph (50 km/h), press this button until
its green indicator lamp comes on; this lamp
appears in grey in the instrument panel.
► The system becomes active at speeds
below 19 mph (30 km/h); this indicator
lamp comes on in green in the instrument panel.
►

When the vehicle begins its descent, you can
release the accelerator and brake pedals; the
system regulates the speed:
– if the gearbox is in first or second gear ,
the speed decreases and the
indicator
lamp flashes rapidly,
–

if the gearbox is in neutral or if the clutch pedal
is depressed, the speed decreases and the
indicator

lamp flashes slowly; in this case, the
maintained descent speed is lower.
On a descent, with the vehicle stationary, if you
release the accelerator and brake pedals, the
system will release the brakes to set the vehicle
gradually in motion.
The brake lamps light up automatically when the
system is regulating.
If the speed exceeds 19 mph (30
km/h),
regulation is paused automatically, the
indicator
lamp goes back to grey in the
instrument panel, but the green indicator lamp in
the button remains on.
Regulation resumes automatically when the
speed falls below 19 mph (30
km/h) again, if the
slope and pedal release conditions are met.
You can depress the accelerator or brake pedal
again at any time.
Switching off
► Press the button until its indicator lamp goes
off; the indicator lamp on the instrument panel
goes off.
At speeds above 43 mph (70
km/h), the system
is automatically deactivated; the indicator lamp in
the button goes off.
Malfunction
If a fault occurs with the system, a message is
displayed in the instrument panel.
Have it checked by a CITROËN dealer or a
qualified workshop.
Seat belts
Inertia reel
The seat belts are equipped with an inertia reel
which allows the strap length to automatically
adjust to your shape. The seat belt returns to its
storage automatically when it is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.

Driving
6Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►

Monitor your environment and keep your
hands on the wheel to be able to react to
anything that may happen any time.
►


Drive smoothly
, anticipate the need for
braking and maintain a longer safety distance,
especially in bad weather.
►

Stop the vehicle to carry out operations that
require close attention (such as adjustments).
►


During long trips, take a break every two
hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In very severe wintry conditions
(temperature below -23°C), let the engine
run for 4 minutes before moving off, to ensure
the correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damaging the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (e.g. dry grass, dead leaves).The
vehicle exhaust system is very hot, even
several minutes after the engine stops. Risk
of fire!
Never leave a vehicle unattended with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P (depending on the
type of gearbox).
Never leave children inside the vehicle
unsupervised.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the internal combustion engine or electric motor,
the gearbox and the electrical systems of the
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.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).

98
Driving
automatically to preserve the remaining battery
charge.
Switching off the engine leads to a loss
of braking assistance.
Starting the engine
Parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then depress the clutch pedal fully.
► With an automatic gearbox, place the gear
selector in mode N or P then depress the brake
pedal fully.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
pre-heating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to two minutes (accelerated idle
speed).
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 causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
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.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, which secret code must be
recognised in order for starting to be possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact the CITROËN dealer.
