Driving safely
SAFETY
Reactivation
The ASR system is reactivated automatically
every time the ignition is switched back on.
- Press this button again to reactivate it manually.
Operating fault If this warning lamp comes on,
accompanied by an audible signal
and a message in the instrument
panel screen, this indicates a fault
with the ASR system.
Have it checked by a CITROËN dealer or a
qualified workshop.
Good practice
The DSC and ASR systems offer exceptional
safety in normal driving, but this should not
encourage the driver to take extra risks or
drive at high speed.
The correct operation of these systems
depend on observation of the manufacturer's
recommendations regarding the wheels
(tyres and rims), the braking components,
the electronic components and assembly
and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a qualified
workshop.
Intelligent Traction Control
System to improve traction on slippery
surfaces (snow, black ice, mud...)
This system checks for situations of difficult
surface adhesion that could make it difficult
to move off or make progress.
In these situations, Intelligent Traction
Control takes over from the ASR system,
by transferring drive to the wheel with the
best grip on the ground to provide the best
traction and trajectory control.
Load inertia control
The true total weight of a commercial vehicle
can vary considerably depending on the load
carried. As a result, the centre of gravity of
the vehicle can move, both longitudinally
and in height.
All such variations have an effect on braking,
traction, the behaviour of the vehicle when
cornering and the tendency to overturn.
Load inertia control estimates the true
total weight of the vehicle by analysing its
behaviour under acceleration and braking.
This system then adapts the operation of
the DSC and ASR systems according to the
weight distribution in the vehicle. In critical
situations, your vehicle than remains more
securely on its intended trajectory.

Seat belts
CAB SEAT BELTS
The front seats are fitted with pre-tensioners
and force limiters.
The bench rear seat is fitted with two seat
belts.
If you install a bench seat after handover, it
must be fitted with seat belts.
REAR SEAT BELTS
The seats/bench seats are fitted with three-
point seat belts and inertia reels.
The centre seat has a seat belt guide and
inertia reel, solid with the seat back.
Height adjustment
Squeeze the control with the return and slide
the assembly on the driver's seat side and
on the side passenger seat side.
The height of the seat belt associated with
the centre seat cannot be adjusted.
Fastening
Pull the strap in front of you, with an even
movement, ensuring that it does not twist.
Secure the buckle in its housing.
Check that the seat belt is fastened securely
and that the automatic locking system is
operating correctly by pulling the strap
rapidly.
Unfastening
Press the "red" button on the buckle
housing, the seat belt rolls up automatically
but you are advised to guide it. As a safety precaution, these
operations should not be carried out
while the vehicle is moving.
Driver's seat belt not fastened warning lamp
CREW CAB
Each rear seat is fitted with a three-point
inertia reel seat belt.
Use the seat belt to restrain one person only
per seat.
If the driver's seat belt is unfastened,
START mode of Stop & Start will not be
invoked. Engine restarting is only possible
with the ignition key. When the vehicle is started, this warning
lamp comes on if the driver has not fastened
their seat belt.

SAFETY
Seat belts
The force limiter reduces the pressure
of the seat belt against the body of the
occupants.
The pretensioning seat belts are active when
the ignition is switched on.
The inertia reels are fitted with a device
which automatically locks the strap in the
event of a collision or emergency braking or
if the vehicle rolls over.
You can unfasten the seat belt by pressing
the red button on the buckle. Guide the seat
belt after unfastening. Good practice
The driver must ensure that passengers
use the seat belts correctly and that they
are all strapped in securely before
moving off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
The seat belts are fitted with an inertia reel
which automatically adjusts the length of the
strap to your size.
Do not use accessories (clothes pegs, clips,
safety pins, etc.) which allow the seat belt
straps to fit loosely.
Ensure that the seat belt has reeled in
correctly after use.
After folding or moving a seat or
a rear bench seat, ensure that the seat
belt has reeled in correctly and that
the buckle is ready to accommodate
the tongue.
Depending on the nature and seriousness of
any impact, the pretensioning device may be
deployed before and independently of infl ation
of the airbags. It instantly tightens the seat
belts against the body of the occupants.
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. The airbag warning lamp also
comes on if the pretensioners are
deployed. Contact a CITROËN
dealer or a qualified workshop.
In order to be effective, a seat belt:
- must restrain one person only,
- must not be twisted, check by pulling in front of you with an even movement,
- must be tightened as close to the body as possible.
The upper part of the seat belt should be
positioned in the hollow of the shoulder.
The lap part should be placed as low as
possible on the pelvis. Do not invert the seat belt buckles as they
will not fulfil their role completely. If the
seats are fitted with armrests, the lap part of
the seat belt should always pass under the
armrest.
Check that the seat belt is fastened correctly
by pulling the strap firmly.
Recommendations for children
Use an appropriate child seat if the
passenger is under 12 years or less than
one and a half metres tall.
Never carry a child on your knees, even with
the seat belt fastened.
For more information on child seats,
refer to the "Safety - Children on board"
section.
In accordance with current safety
regulations, your CITROËN dealer can
guarantee all work or any checks, from
testing to maintenance, on your seat belt
equipment.
Have the seat belts checked regularly (even
after a minor impact) by a CITROËN dealer
or a qualified workshop: they must not show
any signs of wear, cutting or fraying and they
must not be converted or modified.
Clean the seat belt straps with soapy
water or a textile cleaning product, sold
by CITROËN dealers.
