Diesel engine speed
Diesel engines are fitted with injection
equipment which prevents the engine
speed being exceeded irrespective of
the gear selected.
If the message “ Check anti-pollution
system” is displayed on the instrument
panel accompanied by the
Ä and
© warning light; consult an ap -
proved dealer straight away.
When driving, depending on the fuel
grade used, it is possible that white
smoke may be emitted.
This is due to the exhaust particle filter
being cleaned automatically, and does
not affect the way the vehicle runs.
Running out of fuel
If the tank has been completely
drained, the system must be reprimed
after the tank is refilled: see information
on the “fuel tank” in section 1 before re-
starting the engine.
Do not park the vehicle or
run the engine in locations
where combustible sub -
stances or materials such
as grass or leaves can come into
contact with the hot exhaust system.
Precautions to be taken in
winter
To avoid any faults in icy weather:
– ensure that the battery is always fully
charged,
– always keep the diesel tank rela -
tively full to avoid water vapour con-
densing in it and accumulating at the
bottom of the tank.

Advice: antipollution and fuel economy
ADVICe: antipollution, fuel economy and driving (1/3)
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 parts of your vehicle have there-
fore been designed to facilitate future
recycling.
These parts are easy to remove so
that they can be recovered and reproc-
essed by recycling companies.
By virtue of its design, moderate fuel
consumption and initial settings, your
vehicle also conforms to current anti-
pollution regulations. The manufac -
turer is actively striving to reduce pol -
lutant exhaust gas emissions and to
save energy. But the fuel consumption
of your vehicle and the level of pollutant
exhaust gas emissions are also your
responsibility. Ensure that it is main -
tained and used correctly.Aiding fuel economy
Depending on the vehicle, in order to
optimise consumption, an indicator light
on the instrument panel will inform you
of the best moment to upshift or down -
shift gears:
\ shift up a gear;
[ shift down a gear.
Maintenance
It is important to remember that failure to
respect antipollution regulations could
lead to legal action being taken against
the vehicle owner. In addition, replacing
engine, fuel supply system and exhaust
components with parts other than those
originally recommended by the manu -
facturer may alter your vehicle so that
it no longer complies with antipollution
regulations. Have your vehicle adjusted and
checked by an approved 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
–
ignition: this does not require ad -
justment.
– spark plugs: for optimum fuel econ-
omy, efficiency and performance
the specifications laid down by our
Design Department must be strictly
applied.
If the spark plugs have to be
changed, use the make, type and
gap specified for your vehicle’s
engine. Contact an approved dealer
for this.
– idle: this does not require adjust -
ment.
– air filter, diesel filter: a clogged ele-
ment reduces performance. It must
be replaced.

– Sporty driving uses a lot of fuel: drive
with a light right foot.
– Brake as little as possible. If you an-
ticipate an obstacle or bend in ad -
vance, you may then simply release
the accelerator pedal.
– Do not try to maintain the same
speed up a hill, accelerate no more
than you would on the level. Keep
your foot in the same position on the
accelerator pedal.
– Double declutching and accelerating
before switching off are unnecessary
in modern vehicles.
– Bad weather, flooded roads:
Do not drive through floods
if the water is above the
lower edge of the wheel
rims.Driving– Drive carefully for the first few miles
until the engine reaches its normal
operating temperature, rather than
let it warm up while the vehicle is sta-
tionary.
– Speed is expensive.
– Do not overrev the engine in the in-
termediate gears.
Always use the highest gear possi -
ble without labouring the engine.
On versions with an automatic gear-
box, it is preferable to keep the gear
lever in position D.
– Avoid sudden acceleration.
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
your approved dealer as soon as
possible.
Obstructions to the driver
On the driver ’s side, only
use mats adapted to the ve-
hicle that attach to the pre-
installed parts, and regularly check
their mounting. Do not place several
mats on top of each other.
Risk of pedals jamming

Advice on use
– Electricity is fuel; switch off all the
electrical components which are
not really needed. however (safety
first), keep your lights on when the
visibility is bad (“see and be seen”).
– Use the air vents. Driving with the
windows open at 60 mph (100 km/h)
will increase fuel consumption by
4%.
– Avoid using the car for door-to-door
calls (short journeys with long waits
in between) because the engine
never reaches its normal operating
temperature.
tyres
– An underinflated tyre increases fuel
consumption.
– The use of non-recommended tyres
can increase fuel consumption.
–
In vehicles fitted with air condi -
tioning, it is normal to observe an
increase in fuel consumption (es -
pecially in urban conditions) when
it is used. 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:
If the vehicle has been parked in the
sun, open the doors for a few mo -
ments to let the hot air escape before
starting the engine.
– Never fill the fuel tank right to the
brim to avoid overflow.
– Do not leave an empty roof rack
fitted to the vehicle.
– It is better to fit a trailer for bulky ob-
jects.
– When towing a caravan, fit a wind
deflector and adjust it carefully.

electronic stability control
eSC with understeer control
and traction control ASR
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).
t raction control ASR
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 ASR are deactivated.
Consult an approved dealer.

The traction control ASR offers addi -
tional safety, it is recommended that
you do not drive with the function disa-
bled. Correct this as soon as possible
by pressing 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/AIDS (4/4)
Disabling the function ASR
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.

Driving in automatic mode
Select position D. In most traffic con -
ditions, you will not have to touch the
gear selector lever again: the gears will
change automatically at the right time
and at the most suitable engine speed
because the automatic system takes
into account the vehicle load and road
contour and adjusts itself to the particu-
lar driving style you have chosen.
economical driving
When driving, always leave the lever
in position D, keeping the accelerator
pedal lightly depressed to ensure auto-
matic gear changes at a lower engine
speed.
Accelerating and overtaking
Depress the accelerator pedal firmly
and fully (so that it goes beyond the
kickdown point).
this will enable you to change down
to the optimum gear within the
engine range.

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, electronic stability
program (ESP) operational etc.: ESC)
the automatic system may change gear
automatically.
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.
AUt OMA tIC 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 underside
of the vehicle (e.g.: striking
a post, raised kerb or other
street furniture) may result
in damage to the vehicle (e.g.: de -
formation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap -
proved Dealer.

The displayed temperature values
show a comfort level.
When starting the engine, increas -
ing or decreasing the value dis -

does not start instantly at maximum
speed: it gradually increases). This
may take several minutes.
Generally speaking, unless there is
a particular reason not to, the dash-
