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.

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.

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.
LEVELS (2/3)

The engine may be hot
when carrying out opera-
tions in close proximity. In
addition, the engine cooling
fan can come on at any moment.
Risk of injury.
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.

Direction indicator lights
Turn the bulb holder 1 a quarter of a
turn and take out the bulb.
Bulb type: PY21W.
Once the bulb has been replaced,
check that it is properly secured.

Main beam headlight
To change the bulb:
– remove cover B;
– disconnect the wiring 4 (black lead);

Before performing any action in the engine compartment, the ignition
must be switched off by pressing the engine stop button (please see the
information on “Starting, stopping the engine” in Section 2).

5.31
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.
Replacing windscreen wiper
blades 1
With the ignition on and the engine stopped:
– for vehicles equipped with the au- tomatic windscreen wiper function,
lower the windscreen wiper stalk
fully: they stop slightly away from the
bonnet;
– lift the wiper arm 2;
– press the button firmly 3 then remove the blade 1.

OPERATING FAULTS (3/6)
On the roadPOSSIBLE CAUSESWHAT TO DO
Vibrations. Tyres not inflated to correct pres-
sures, incorrectly balanced or dam-
aged. Check the tyre pressures: if this is not the
problem, have them checked by an ap-
proved Dealer.
White smoke from the exhaust. In the diesel version, this is necessar-
ily a fault. Smoke may be caused by
particle filter regeneration. Please refer to the information on “Special
features of diesel versions” in Section 2.
Smoke under the bonnet. Short-circuit or cooling system leak. Stop, switch off the ignition, stand away
from the vehicle and contact an approved
dealer.
The oil pressure warning light comes
on: while cornering or braking The level is too low. Top up the engine oil level (refer to the in-
formation on “Engine oil level: topping up,
filling” in Section 4).

OPERATING FAULTS (4/6)
On the roadPOSSIBLE CAUSESWHAT TO DO
Steering becomes heavy. Assistance overheating. Consult an approved dealer.
The engine is overheating. The cool-
ant temperature indicator is in the
warning zone and warning light
® comes on. Engine cooling fan not working. Stop the vehicle, switch off the engine and
contact an approved dealer.
Coolant leaks. Check the coolant reservoir: it should con- tain fluid. If there is no coolant, consult an
approved dealer as soon as possible.
Coolant boiling in the coolant reser-
voir. Mechanical fault: damaged cylinder
head gasket. Stop the engine.
Contact an approved dealer.
Radiator:
If there is a significant lack of coolant, remember that it must never b\
e topped up using cold coolant while
the engine is very warm. After any procedure on the vehicle which has involved even partial drain\
ing of the cooling
system, it must be refilled with a new mixture prepared in the correct p\
roportions. Reminder: only products approved
by our Technical Department may be used for this purpose.
