engine is running (in order to prevent
the vehicle from moving without the
driver). A beep draws your attention to
this and the message “release manu -
ally” is displayed on the instrument
panel.
If no lights or sounds are
apparent, this indicates
a fault in the instrument
panel. This indicates that it
is essential to stop immediately
(as soon as traffic conditions

correctly immobilised and contact
an approved Dealer.Never leave your vehicle
without moving the selec -
tor lever to position P or N.
This is because when the
vehicle is stationary with the engine
running and a gear engaged, the
vehicle may begin to move if you
accelerate.

aDVICe: antipollution, fuel economy and driving (2/3)
– Avoid sudden acceleration.
– 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.
– Sporty driving uses a lot of fuel: drive
with a light right foot.
– 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.
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.

aBS (anti-lock braking
system)
Under heavy braking, the ABS prevents
the wheels from locking, allowing the
stopping distance to be managed and
keeping control of the vehicle.
Under these circumstances, the vehi -
cle can be steered to avoid an obstacle
whilst braking. In addition, this system
can increase stopping distances, par -
ticularly on roads with low surface grip
(wet ground etc.).
You will feel a pulsation through the
brake pedal each time the system is
activated. The ABS does not in any way
improve the vehicle's physical perform-
ance relating to the road surface and
roadholding. It is still essential to follow
the rules of good driving practice (such
as driving at a safe distance from the
vehicle in front etc.).
Driver correction devices and aids
DRIVeR CoRReCtIoN DeVICeS aND aIDS (1/5)
Depending on the vehicle, they may
comprise:
– t h e aB S ( a n t i - l o c k b r a k i n g
system);
– eSC (electronic stability program)
with understeer control and a SR
traction control;
– emergency brake assist with, de -
pending on the vehicle, braking
anticipation;
– rear wheel steering.
In an emergency, apply firm and
continuous pressure to the brake
pedal. There is no need to pump
it repeatedly. The ABS will modu -
late the force applied in the braking
system.
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle behav -
iour to be adapted to suit the driving
conditions.
However, the functions do not take
the place of the driver. they do
not increase the vehicle’s limits
and should not encourage you
to drive more quickly. Therefore,
they can under no circumstances
replace the vigilance or responsibil -
ity of the driver when manoeuvring
the vehicle (the driver must always
be ready for sudden incidents which
may occur when driving).

However, it is dangerous
to brake suddenly and
it is essential to stop immediately,
as soon as traffic conditions allow.
Contact an approved dealer.

hill start assistance
This function assists the driver when
starting on hills. It prevents the vehicle
from rolling backwards, depending on
the slope, by automatically applying the
brakes when the driver lifts his/her foot
off the brake pedal to depress the ac -
celerator pedal.
System operation
It only operates when the gear lever is
in a position other than neutral (other
than N or P for automatic transmis -
sions) and the vehicle is completely
stationary (brake pedal depressed)
The system holds the vehicle for ap -
proximately 2 seconds. The brakes are
then gradually released (the vehicle will
move according to the slope).
The hill start assistance
system cannot completely
prevent the vehicle from
rolling backwards in all sit -
uations (extremely steep gradients,
etc.).
In all cases, the driver may depress
the brake pedal to prevent the vehi-
cle from rolling backwards.
The hill start assistance function
should not be used for prolonged
stops: use the brake pedal.
This function is not designed to im-
mobilise the vehicle permanently.
If necessary, use the brake pedal to
stop the vehicle.
The driver must remain particularly
vigilant when driving on slippery or
low-grip surfaces and/or on hills.
Risk of serious injury.

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, warning 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.
