DRIVING CORRECTION DEVICES AND AIDS (2/5)
Electronic stability program
(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.
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).
Operating faults
When the system detects an operat-
ing fault, the
© and  warn-
ing lights come on and, depending on
the vehicle, the message “Check ESC”
appears on the instrument panel. In
this case, the ESC and traction control
system are deactivated.
Consult an approved dealer.

2.30
Operating faults
If the system detects a fault, the mes-
sage “Check blind spot alert” is dis-
played on the instrument panel. Call an
approved Dealer.
Note: when the engine is started, the
indicator light 4, display B , flashes
three times. It is normal.
– The system’s detection
range operates according
to a standard lane width. If
you are driving in wide traf-
fic lanes, the system might not
be able to detect a vehicle in the
blind spot.
– The system might be disrupted momentarily if it is exposed to
strong electromagnetic waves
(as beneath high-tension power
lines) or to very poor weather
conditions (heavy rain, snow,
etc.). Remain aware of driving
conditions.
There is a risk of accidents.
BLIND SPOT WARNING (3/3)
Because sensors have
been installed in the bum-
pers, any work (repairs, re-
placements, touching up of
paintwork) must be carried out by a
qualified professional.

Conditions for non-function
– If the object is not moving;
– if traffic is heavy;
– the road is winding;
– if front and rear sensors both detect objects at the same time (e.g. when
passing an articulated lorry).
– ...
This function is an addi-
tional aid which indicates
other vehicles in the blind
spot area.
It can never in any case be a sub-
stitute for care nor for the driver’s
responsibility while in charge of his
vehicle.
The driver should always be ready
for sudden incidents while driv-
ing: always ensure that there are
no small, narrow moving obstacles
(such as a child, animal, pushchair,
bicycle, stone, post, etc.) in the blind
spot when manoeuvring.

BONNET (2/2)
Closing the bonnet
Check that nothing has been left in the
engine compartment.
To close the bonnet again, hold the
bonnet in the middle and lower it to
30 cm above the closed position, then
release it. It will latch automatically
under its own weight.
After carrying out any work
in the engine compart-
ment, check that nothing
has been left behind (cloth,
tools, etc.).
These may damage the engine or
cause a fire.
Ensure that the bonnet is
properly locked.
Check that nothing is pre-
venting the catch from lock-
ing (gravel, cloth, etc.).
In the event of even a slight
impact involving the radia-
tor grille or bonnet, have
the bonnet lock checked by
an approved dealer as soon as pos-
sible.

Engine oil grade
Refer to the Maintenance Service
Booklet for your vehicle.
ENGINE OIL LEVEL: topping up, filling (2/2) OIL CHANGE
Never run the engine in an
enclosed space as exhaust
gases are poisonous.
Engine oil change: if you
are changing the oil when
the engine is hot, be careful
not to scald yourself if the
oil overflows.
Filling: take care when
topping up the oil that
no oil drips onto engine
components - risk of fire.
Remember to refit the cap securely
as there is a risk of fire if oil splashes
onto hot engine components.When working in the engine
compartment, ensure that
the windscreen wiper stalk
is in the park position.
Risk of injury.
Please note when work-
ing close to the engine that
it may be hot. The engine
cooling fan may also start
at any moment. The
 warning
light in the engine compartment re-
minds you of this.

Oil change
Service interval: refer to the
Maintenance Service Booklet for your
vehicle.
Oil change capacity
Please refer to the maintenance docu-
ment for your vehicle, or contact an au-
thorised dealer.
Always check the engine oil level using
the dipstick, as explained previously (it
should never fall below the minimum
level, or be over the maximum level on
the dipstick).
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
Exceeding the maximum
engine oil level
Under no circumstances
must the maximum fill level
be exceeded: risk of damage to the
engine and catalytic converter.
If the oil level exceeds the maximum
level, do not start your vehicle and
contact an approved Dealer.

4.8
Level 2
It is normal for the level to drop as the
brake shoes become worn, but it must
never drop lower than the “MINI" warn-
ing line.
If you wish to check the disc and drum
wear yourself, you should obtain the
document explaining the checking pro-
cedure from the manufacturer’s net-
work or web site.
Topping up
After any operation on the hydraulic cir-
cuit, a specialist must replace the brake
fluid.
Only use fluids approved by our
Technical Department (and taken from
a sealed container).
Replacement interval
Refer to the Maintenance Document for
your vehicle.
Brake fluid level
The level should be read with the engine
switched off and on level ground.
This should be checked frequently,
and immediately if you notice even the
slightest loss in braking efficiency.

WINDSCREEN WIPER BLADES (1/2)
Check the condition of the wiper
blades. You are responsible for their
service life:
– clean the blades, windscreen and rear screen regularly with soapy
water;
– do not use them when the wind- screen or rear screen are dry;
– free them from the windscreen or rear screen when they have not
been used for a long time.
– In frosty weather, make
sure that the wiper blades
are not stuck by ice (to
avoid the risk of the motor
overheating).
– Check the condition of the wiper
blades.
They should be replaced as soon
as they become less efficient: ap-
proximately once a year.
When changing the blade, when it
has been removed, do not let the
wiper arm fall against the window:
risk of breaking the window.
To refit
To refit the wiper blade 1, insert it in its
housing in the arm 2, then clip it until
you hear a click. Make sure that the
blade is correctly locked in position.
For vehicles equipped with the auto-
matic windscreen wiper function, lift the
windscreen wiper stalk fully: the front
windscreen wiper blades will settle
down onto the bonnet.
