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.
DRIVING CORRECTION DEVICES AND AIDS (2/5)
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.
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 vigi-
lance or responsibility of the driver
when manoeuvring the vehicle (the
driver must always be ready for
sudden incidents which may occur
when driving).

2.23
DRIVING CORRECTION DEVICES AND AIDS (3/5)
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. 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.
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.
Operating faults
When the system detects an operating
fault the message “CHECK BRAKING
SYSTEM” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.
Driver assistance with a
trailer
This system helps to maintain control
over the vehicle while using a trailer.
It detects shaking caused by towing a
trailer under certain driving conditions.
Operating conditions
– the towbar must be approved by an authorised dealer;
– the harness must be approved by an authorised dealer;
– the towbar must be connected to the vehicle.
Operating principle
The function stabilises the vehicle by:
– asymmetric braking of the front wheels to reduce shaking caused by
the trailer;
– braking of all four wheels and limita- tion on engine torque to reduce the
vehicle speed until the shaking has
stopped.
Warning light
 flashes on the in-
strument panel to inform the driver.

2.36
Temporary deactivation of
the system

vate the system and switch off the in-
dicator light.
Depending on the vehicle, you can de-
activate the parking distance control
from the touch-screen. Please see the
equipment instructions for further infor-
mation.
PARKING DISTANCE CONTROL (2/2)
Adjusting the parking
distance control volume
Depending on the vehicle, certain set-
tings can be adjusted from the touch-
screen 1. Please see the equipment in-
structions for further information.
The system is automatically reactivated
after the ignition is switched off and the
engine restarted.
Prolonged deactivation of the
system
You can deactivate the system perma-
nently by pressing and holding switch 2.
The warning light built into the switch
remains lit constantly.
The deactivated system can be re-
activated by pressing and holding the
switch again.
Operating faults
Depending on the vehicle, when the
system detects an operating fault, the
message “check parking distance con-
trol” appears on the instrument panel,
accompanied by the warning light
© and a beep lasting approxi-
mately 5 seconds. Please contact an
authorised dealer.

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.
Do not press down on the
bonnet: there is a risk that
the bonnet may accidentally
close.
When working in the engine
compartment, ensure that
the windscreen wiper stalk
is in the park position.
Risk of injury.
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.
After any procedure in the
engine compartment, make
sure that you do not forget
anything (cloth, tools, etc.).
These may damage the engine or
cause a fire.
Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).

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)
2
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
Frequency of checking coolant level
Check the coolant level regularly
(very severe damage is likely to be
caused to the engine if it runs out of
coolant).
If the level needs to be topped up, only
use products approved by our Technical
Department which ensure:
– protection against freezing;
– an anti-corrosion protection for the cooling system.

WINDSCREEN WIPER BLADES (1/2)
– 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.
Replace the wiper blades as soon
as they begin to lose efficiency
(approximately once a year).
Whilst changing the blade, take care
not to drop the arm onto the window
after it has been removed as this
may break the window.
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.
To refit
To refit the wiper blade, proceed in re-
verse order to removal. Make sure that
the blade is correctly locked in position.
Raise the windscreen wiper stalk fully:
the front windscreen wiper blades will
settle down onto the bonnet.
Replacing windscreen wiper
blades
With the ignition on and the engine stopped:
– lower the windscreen wiper stalk fully: they stop slightly away from the
bonnet;
– lift the wiper arms 1 and 2;
– pull the tab 4 (movement A) and
push the blade 3 upwards.

On the roadPOSSIBLE CAUSESWHAT TO DO
Steering becomes heavy. Assistance overheating. Consult an approved dealer.
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.
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.
