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.

LANE DEPARTURE WARNING (1/2)
This function is a driving aid in the event of the accidental crossing o\
f
a continuous or broken line in the road. However, the function is not in-
tended to replace the driver. The function can be disrupted under certain
conditions, including:
– poor visibility (rain, snow, fog, dirty windscreen, glare of the sun, partially ob- scured road lines, etc.);
– roads with tight bends;
– closely following a vehicle in the same lane;
– worn road markings, difficult to distinguish or spaced very widely apart;

Manual use
Pressing button 11 allows air recircula-
tion to be forced, in which case the in-
tegrated warning light comes on as well
as warning light 14.
Prolonged use of this position may lead
to odours, caused by non-renewal of
air, and the formation of condensation
on the windows.
We therefore advise you to return to au-
tomatic mode as soon as the air recir-
culation function is no longer required,
by pressing button 11 again.Stopping the system
Press button 7 to switch off the system;
in this case “OFF” is shown on the dis-
play 13. To switch the system on, press
one of the 2, 3 or 4 switches.
Recycling
This function is managed automati-
cally (operation is confirmed by warn-
ing light 14 on display 13), but you can
also activate it manually.
Note:
– during recirculation, air is taken from the passenger compartment and
is recycled, with no air being taken
from outside the vehicle;
– air recirculation allows the external atmosphere to be cut off (when driv-
ing in polluted areas, etc.);
– lowering the passenger compart- ment temperature as quickly as pos-
sible.
AUTOMATIC CLIMATE CONTROL (5/5)
The demisting/de-icing will still take
priority over the air recirculation.

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 be-
tween oil changes.
However, contact your approved
Dealer if more than 0.5 litres is being
consumed 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 ve-
hicle 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.

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).
Replacement intervals
Refer to the Maintenance Document for
your vehicle.

Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
Before performing any
action in the engine com-
partment, the ignition must
be switched off by pressing
the engine stop button (please see
the information on “Starting, stop-
ping the engine” in Section 2).
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.
