MAINTENANCE AND ANTIPOLLUTION ADVICE
Your vehicle complies with criteria for
recycling and recovering vehicles at the
end of their service life, which will come
into force in 2015.
Some of the parts on your vehicle have
been designed to be recycled later.
These parts are easily removable in
order to be collected and reprocessed
in recycling networks.
Furthermore, by virtue of its design,
moderate fuel consumption and initial
settings, your vehicle also conforms
to current anti-pollution regulations.
The manufacturer is actively striving
to reduce pollutant exhaust gas emis-
sions and to save energy. However,
the fuel consumption of your vehicle
and the level of pollutant exhaust gas
emissions are also your responsibility.
Ensure that it is maintained and used
correctly.Maintenance
It is important to remember that fail-
ure to respect anti-pollution regulations
could lead to legal action being taken
against the vehicle owner.
In addition, replacing engine, fuel
supply system and exhaust compo-
nents with parts other than those origi-
nally recommended by the manufac-
turer may alter your vehicle so that it
no longer complies with anti-pollution
regulations.
Have your vehicle adjusted and
checked by an authorised dealer, in ac-
cordance with the instructions given in
your maintenance schedule: they will
have all the equipment necessary for
ensuring that your vehicle is maintained
to its original standard.
Engine adjustments
– Air filter, fuel filter: a choked ele-
ment will reduce efficiency. It must
be replaced.
– Idle speed: no adjustment is needed.
Exhaust gas monitoring
system
The exhaust gas monitoring system will
detect any operating faults in the vehi-
cle’s antipollution system.
If this system malfunctions, toxic sub-
stances may be released into the at-
mosphere or damage may occur.
ÄThis warning light on the in-
strument panel will indicate if
there are any faults in the system:
This lights up when the ignition is
switched on and goes out when the
engine is started.
– If it lights up continuously, consult an approved Dealer as soon as possi-
ble;
– if it flashes, reduce the engine speed until the light stops flashing. Contact
an authorised dealer as soon as pos-
sible.

DRIVER CORRECTION DEVICES AND AIDS (2/4)
Electronic stability control
ESC with understeer control
and traction control
Electronic stability control ESC
This system helps you to keep control
of the vehicle in critical driving condi-
tions (avoiding an obstacle, loss of grip
on a bend, etc.).
Operating principle
A sensor in the steering wheel detects
the direction selected by the driver.
Other sensors throughout the vehicle
measure the actual direction.
The system compares driver input to
the actual trajectory of the vehicle and
corrects the trajectory if necessary by
controlling the braking of certain wheels
and/or engine power. In the event that
the system is engaged, indicator light
 flashes on the instrument panel.Understeer control
This system optimises the action of the
ESC in the case of pronounced under-
steer (loss of front axle road holding).
Traction control
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
Operating principle
Using the wheel sensors, the system
measures and compares the speed of
the drive wheels at all times and slows
down their over-rotation. If a wheel is
starting to slip, the system brakes au-
tomatically until the drive supplied be-
comes compatible with the level of grip
under the wheel again.
The system also adjusts the engine
speed to the grip available under the
wheels, independently of the pressure
exerted on the accelerator pedal. Operating faults
When the system detects an operat-
ing fault the message “Check ESC” and
warning light
© appear on the in-
strument panel.
In this case, the ESC and traction
control system are deactivated. Consult
an authorised dealer.

2.26
The traction control system offers ad-
ditional safety. It is recommended that
you do not drive with the function di-
sabled. Correct this as soon as pos-
sible by pressing the switch 1 again.
Note: the function is reactivated auto-
matically when the ignition is switched
on or when a speed of approximately
24 mph (40 km/h) is exceeded.
Emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
Operating principle
The system is for detecting an emer-
gency braking situation. In this case,
the braking assistance immediately de-
velops maximum power and may trig-
ger ABS regulation.
ABS braking is maintained as long as
the brake pedal is applied.
Hazard warning lights switching on
Depending on the vehicle, these may
light up in the event of sudden decel-
eration.
Operating faults
When the system detects an operat-
ing fault the message “Check brak-
ing system” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.
Braking anticipation
Depending on the vehicle, when you
rapidly release the accelerator, the
system anticipates the braking ma-
noeuvre in order to reduce stopping
distances.
Special cases
When using the cruise control:
– if you use the accelerator, when you release it, the system may be trig-
gered;
– if you do not use the accelerator, the system will not be triggered.
DRIVER CORRECTION DEVICES AND AIDS (3/4)
Disabling the traction control
system
In some situations (driving on very wet
ground: snow, mud, etc. or driving with
snow chains fitted), the system may
reduce the engine output to limit wheel-
spin. If this is not required, it is possible
to deactivate the function by pressing
switch 1.
The message “Traction control off” is
displayed on the instrument panel to
inform you.

Parking the vehicle
When the vehicle is stopped, move the
lever to position P while keeping your
foot on the brake pedal: the gearbox is
in neutral and the drive wheels are me-
chanically locked by the driveshaft.
Apply the handbrake or, depending
on the vehicle, ensure that the elec-
tronic parking brake is applied.
Special circumstances
– If the road contours and bends
do not allow you to stay in auto-
matic mode (e.g.: in the mountains),
we recommend that you change to
manual mode.
This will prevent the automatic gear-
box from changing gears repeatedly
when climbing, and permit engine
braking on long descents.
– In cold weather, to prevent the
engine from stalling, wait a few mo-
ments before shifting the selector
lever from position P or N and en-
gaging D or R.
Driving in manual mode
With the selector lever in position D,
move the lever to the left. Shifting the
lever repeatedly allows you to change
gears manually:
– To move down through the gears, push the lever backwards;
– To move up through the gears, push the lever forwards.
The gear selected is displayed on the
instrument panel.
Special cases
Under certain driving conditions (e.g.
engine protection, or electronic stabil-
ity program (ESP) operational etc.): the
automatic system may change gear au-
tomatically.
Likewise, to prevent incorrect manoeu-
vres, a gear change may be refused by
the automatic system: in this case the
gear display flashes for a few seconds
as a warning.
AUTOMATIC TRANSMISSION (2/3)
In very cold weather, the system
may prevent the gears from being
shifted in manual mode until the
gearbox reaches the right tempera-
ture.
An impact to the under-
side of the vehicle while
manoeuvring (e.g.: strik-
ing a post, raised kerb or
other street furniture) may result in
damage to the vehicle (e.g.: defor-
mation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap-
proved Dealer.

Before opening the roof
– Perform the procedure with the engine running (risk of battery dis-
charging) and the vehicle stationary.
– Ensure that the boot divider 1 is well
tensioned and that the boot is fully
closed.
Note: If one of these conditions is
not met, the message “Roof: shut
boot blind” or “Roof: see handbook”
appears on the instrument panel.
– Ensure that no object has been left in the part reserved for the roof (above
the divider 1).
– Make sure that no object is pushing up the boot divider 1.
– Make sure that no object projects above the boot divider 1.
– Check that no object has been left on the roof, on the luggage compart-
ment lid or on the parcel shelf behind
the rear headrests.
– Remove any ice or snow (risk of seal damage).
To avoid all risk of injury,
ensure that nobody is in
the proximity of the moving
parts.
When opening or closing the roof,
ensure that nothing interferes with
the moving parts (roof and luggage
compartment lid).

AIR CONDITIONING: information and advice on use
Fuel consumption
You will normally notice an increase
in fuel consumption (especially
when driving in town) when the air
conditioning is operating.
For vehicles fitted with manual air
conditioning, switch off the system
when it is not required.
Advice for reducing
consumption and therefore
helping to preserve the
environment:
Drive with the air vents open and
the windows closed.
If the vehicle has been parked in
the sun, open the doors for a few
moments to let the hot air escape
before starting the engine.
Maintenance
Refer to the Maintenance
Document for your vehicle for the in-
spection frequency.Operating faults
As a general rule, contact your ap-
proved Dealer in the event of an op-
erating fault:
– reduction in de-icing, demist-
ing or air conditioning per-
formance. This may be caused
by the passenger compartment
filter cartridge becoming clogged;
– no cold air is being produced.
Check that the controls are set
correctly and that the fuses are
sound. Otherwise, switch off the
system.
Advice on use
In some situations, (air conditioning
off, air recirculation activated, venti-
lation speed at zero or low, etc.) you
may notice that condensation starts
to form on the windows and wind-
screen.
If there is condensation, use the
“Clear View” function to remove it,
then use the air conditioning in auto-
matic mode to stop it forming again.
If the condensation does not clear,
use the FAST programme.
Do not open the refriger-
ant fluid circuit. The fluid
may damage eyes or skin.
Note
Presence of water under the ve-
hicle. After prolonged use of the air
conditioning system, it is normal for
water to be present under the vehi-
cle. This is caused by condensation.
