SAFETY
TRAJECTORY CONTROL
SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation (also known as
Traction Control) optimises traction to
prevent skidding of the wheels, by act-
ing on the brakes of the driving wheels
and on the engine.
The electronic stability programme acts
on the brake of one or more wheels and
on the engine to keep the vehicle on the
trajectory required by the driver.
Activation
These systems are activated automati-
cally each time the vehicle is started.
They come into operation in the event
of a grip or trajectory problem. This is indicated by fl ashing of
this warning lamp on the instru-
ment panel. Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), it may be ad-
visable to deactivate the ASR and ESP
systems, so that the wheels can move
freely and regain grip.

 Press the "ESP OFF" button, located
on the left below the steering wheel.
If this warning lamp comes on in
the instrument panel and the in-
dicator lamp on the button comes
on, this indicates that the ASR and
ESP systems are deactivated.
Reactivation
These systems are reactivated automat-
ically each time the ignition is switched
back on or from 30 mph (50 km/h).

 Press the "ESP OFF" button again
to reactivate them manually. Operating fault
If this warning lamp comes on,
accompanied by an audible sig-
nal and a message on the mul-
tifunction screen, this indicates
a malfunction of these systems.
Have the systems checked by a
CITROËN dealer.
The ESP/ASR systems offer ex-
ceptional safety in normal driving,
but this should not encourage the
driver to take extra risks or drive at
high speed.
The correct functioning of these
systems depends on observa-
tion of the manufacturer's rec-
ommendations regarding the
wheels (tyres and rims), the brak-
ing components, the electronic
components and the CITROËN
assembly and operation proce-
dures.
After an impact, have these sys-
tems checked by a CITROËN
dealer.

CHECKING LEVELS
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 15 minutes.
The check is carried out either
when the ignition is switched on using
the oil level indicator on the instrument
panel, or using the dipstick.
Between two oil changes, the consump-
tion should not exceed 0.5 litre per
600 miles (1,000 km).
Engine oil change
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil grade
The oil must be suitable for your engine
and conform to the manufacturer's rec-
ommendations. Brake fluid level
The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Changing the fluid
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
Fluid specification
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.
Coolant level The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the ig-
nition off.

On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may oper-
ate after the vehicle has been switched
off, even if the engine 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.
Changing the coolant
The coolant does not have to be
changed.
Fluid specification
The coolant must conform to the manu-
facturer's recommendations.
Screenwash fluid level
Top up the level when necessary.
Fluid specification
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with water.
Take care when carrying out
checks under the bonnet as
some parts of the engine can be
very hot (risk of burns).

ing of the service warning lamp, accom-
panied 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 CITROËN
dealer (France) or an authorised
waste disposal site. CHECKS
Unless otherwise indicated, check
these components in accordance with
the Maintenance and Warranty Guide
and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not require
any maintenance.
However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "Practical information" sec-
tion for details of the precautions to be
taken before disconnecting the battery
and following its reconnection.
Air filter and passenger
compartment filter Refer to the Maintenance and
Warranty Guide for details of
the replacement intervals for
these components.
Depending on the environment
(e.g. dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary (re-
fer to the "Engines" paragraph).
A clogged cabin fi lter may have an ad-
verse effect on the performance of the
air conditioning system and generate
undesirable odours. Oil filter
Replace the oil fi lter each time
the engine oil is changed.
Refer to the Maintenance and
Warranty Guide for details of
the replacement interval for
this component.
Particle emission filter (Diesel)
It is imperative that the maintenance of
the particle emission fi lter is carried out
by a CITROËN dealer.
Following prolonged operation of
the vehicle at very low speed or
at idle, you may, in exceptional
circumstances, notice the emis-
sion of water vapour at the ex-
haust on acceleration. This does
not affect the behaviour of the
vehicle or the environment.
