DRIVER CORRECTION DEVICES AND AIDS (2/4)
Electronic stability control
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. 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 traction
control system are deactivated. Consult
an authorised dealer.

2.26
The traction control system offers ad-
ditional safety. It is recommended that
you do not drive with the function di-
sabled. Correct this as soon as pos-
sible by pressing the 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 AND AIDS (3/4)
Disabling the traction control
system
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.

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, or electronic stabil-
ity program (ESP) operational etc.): the
automatic system may change gear au-
tomatically.
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.
AUTOMATIC 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 under-
side of the vehicle while
manoeuvring (e.g.: strik-
ing a post, raised kerb or
other street furniture) may result in
damage to the vehicle (e.g.: defor-
mation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap-
proved Dealer.

3.11
AIR CONDITIONING: information and advice on use
Fuel consumption
You will normally notice an increase
in fuel consumption (especially
when driving in town) when the air
conditioning is operating.
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:
Drive with the air vents open and
the windows closed.
If the vehicle has been parked in
the sun, open the doors for a few
moments to let the hot air escape
before starting the engine.
Maintenance
Refer to the Maintenance Document
for your vehicle for the inspection
frequency.Operating faults
As a general rule, contact your ap-
proved Dealer in the event of an op-
erating fault:
– reduction in de-icing, demist-
ing or air conditioning per-
formance. This may be caused
by the passenger compartment
filter cartridge becoming clogged;
– no cold air is being produced.
Check that the controls are set
correctly and that the fuses are
sound. Otherwise, switch off the
system.
Advice on use
In some situations, (air conditioning
off, air recirculation activated, venti-
lation speed at zero or low, etc.) you
may notice that condensation starts
to form on the windows and wind-
screen.
If there is condensation, use the
“Clear View” function to remove it,
then use the air conditioning in auto-
matic mode to stop it forming again.
If the condensation does not clear,
use the FAST programme.
Do not open the refriger-
ant fluid circuit. The fluid
may damage eyes or skin.
Note
Presence of water under the ve-
hicle. After prolonged use of the air
conditioning system, it is normal for
water to be present under the vehi-
cle. This is caused by condensation.

4.3
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 guide it down,
allowing a 30 cm gap before it is closed,
then release it. It will latch automatically
under its own weight.
Ensure that the bonnet is
properly locked.
Check that nothing is pre-
venting the catch from lock-
ing (gravel, cloth, etc.).
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.
In the event of even a slight
impact involving the radia-
tor grille or bonnet, have the
bonnet lock checked by an
authorised dealer as soon as pos-
sible.

ENGINE OIL LEVEL: general information (1/2)
Minimum oil level warning on
the instrument panel
When the message “Checking control
functions” is displayed, press either
button 3 or 4.
If the level is above the minimum
level : the message “Oil level” will be
shown on the display with squares 1,
which are replaced by dashes when the
level drops 2.
Note: The detailed level cannot be dis-
played if the vehicle was previously
only driven for a short time. If the level is at the minimum
The “Top up oil level” message and
warning light © are displayed on
the instrument panel.
It is vital to top up the oil as soon as
possible.
The display only warns the
driver if the oil level is at the
minimum level. It does not
inform the driver that the oil
level has exceeded the maximum
level as this can only be measured
using a dipstick.
It is normal for an engine to use oil for
lubrication and cooling of moving parts
and it is normal to top up the level
between oil changes.
However, contact your approved Dealer
if more than 0.5 litres is being consu-
med every 600 miles (1,000 km) after
the running in period.
Oil change frequency: check the oil
level from time to time and certainly
before any long journey to avoid the
risk of damaging your engine.
Reading the oil level
The oil level should be read with the
vehicle on level ground, after the engine
has been switched off for some time.
The dipstick must be used to read
the exact oil level and make sure
that the maximum level has not been
exceeded (risk of engine damage).
Refer to the following pages.
The instrument panel display only
alerts the driver when the oil level is at
its minimum.

ENGINE OIL LEVEL: topping up, filling (1/3)
Topping up/filling
The vehicle must be parked on level
ground and the engine should be cold
(for instance, before the engine is
started up for the first time in the day). – Unscrew cap
1;
– top up the level (as a guide, the ca- pacity between the minimum and
maximum reading on the dipstick 2
is between 1.5 and 2 litres, depend-
ing on the engine);
– wait for approximately 10 minutes to allow the oil to flow into the engine;
– check the level using the dipstick 2
(as described above).
Once the operation has been com-
pleted, ensure that the dipstick is
pushed in as far as it will go or that the
cap-type dipstick is completely screwed
in.
Do not exceed the max level and
do not forget to refit cap 1 and dip-
stick 2.

ENGINE OIL LEVEL: topping up, filling (3/3)/OIL CHANGE
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.
Never run the engine in an
enclosed space as exhaust
gases are poisonous.
Oil change

LEVELS (1/3)
Coolant
With the engine switched off and on
level ground, the level when cold must
be between the “MINI" and "MAXI"
marks on coolant reservoir 1.
Top this level up when cold before it
reaches the MINI mark. Checking intervals
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;
– anticorrosion protection of the coo- ling system.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.

LEVELS (2/3)
Brake fluid level
The level should be read with the engine
switched off and on level ground. This
should be checked frequently, and any
time you notice even the slightest loss
in braking efficiency. Level 2
It is normal for the level to drop as
the linings become worn, but it should
never drop below the “MINI” warning
line.
If you wish to check the disc and drum
wear yourself, you should obtain the
document explaining the checking pro-
cedure from our network or from the
manufacturer’s website. Topping up
After any operation on the hydraulic cir-
cuit, a specialist must replace the fluid.
Only use fluids approved by our
Technical Department (and taken from
a sealed container).
