AIR BAGS
System designed to maximise
the safety of the occupants (with
the exception of the rear centre
passenger) in the event of violent
collisions. It supplements the action
of the force-limiting seat belts.
If a collision occurs, the electronic
detectors record and analyse the
front and side impacts sustained in
the impact detection zones:
- in the case of a serious impact, the air bags are triggered instantly
and protect the occupants of the
vehicle (with the exception of the
rear centre passenger); immedi-
ately after the impact, the air bags
defl ate rapidly so that they do not
hinder visibility or the exit of the
occupants,
- in the case of a minor or rear im- pact or in certain roll-over con-
ditions, the air bags will not be
triggered; the seat belt alone is
suffi cient to provide optimum
protection in these situations.
The air bags do not operate when
the ignition is switched off.
This equipment will only operate once.
If a second impact occurs (during the
same or a subsequent accident), the
air bag will not operate. Impact detection zones

A. Front impact zone.

B. Side impact zone.
Triggering of the air bag(s) is ac-
companied by a slight emission of
harmless smoke and a noise, due to
the activation of the pyrotechnic car-
tridge incorporated in the system.
This smoke is not harmful, but sen-
sitive individuals may experience
slight irritation.
The noise of the detonation may
result in a slight loss of hearing for
a short time. Front airbags
System which protects the head and
chest of the driver and front passen-
ger in the event of a front impact.
The driver’s airbag is incorporated
in the centre of the steering wheel;
the front passenger’s airbag is incor-
porated in the dashboard above the
glove box.
Activation
The airbags are triggered simultane-
ously, unless the passenger’s front
airbag is deactivated, in the event of
a serious front impact to all or part of
the front impact zone
A , in the longi-
tudinal centreline of the vehicle on
a horizontal plane and directed from
the front to the rear of the vehicle.
The front airbag infl ates between the
front occupant of the vehicle and the
dashboard to cushion their forward
movement.

Screenwash and headlamp
wash fluid
Fluid specifi cation

For optimum cleaning and to avoid free-
zing, this fl uid must not be topped up or
replaced with water.
Reservoir capacities:
- screenwash: approximately 3.5 litres,
- screenwash and headlamp wash: approximately 6.15 litres.
Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.
Used products
Avoid prolonged contact of
used oil or fl uids with the
skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or
fl uids into sewers or onto
the ground.
Take used oil to a an authorised
waste disposal site CITROËN.
In the case of vehicles fi tted
with headlamp washers, the
minimum level of this fl uid is
indicated by an audible signal
and a message on the multifunction
screen.
Top up the level when you stop the
vehicle.
Coolant level
Coolant change
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer’s recommendations. The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the en-
gine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour
after switching off the engine before
carrying out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.
