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

on the instrument panel.
In this case, the ESC and traction con-
trol system are deactivated. Consult an
authorised dealer.

DRIVING CORRECTION DEVICES AND AIDS (3/4)
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 assistThis system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
Operating principle
The system detects an emergency
braking situation. In this case, the brak-
ing assistance immediately develops
maximum power and may trigger ABS
regulation. ABS braking is maintained
as long as the brake pedal is not re-
leased.
Hazard warning lights illumination
Depending on the vehicle, these may
light up in the event of sudden decel-
eration.
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).
Deactivating the function
(depending on vehicle)
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 “ESC off” is displayed on
the instrument panel to inform you.

2.35
Mode selector
Depending on the road conditions, turn-
ing the selector 1 enables the following
modes to be selected:
– AUTO ;
– 2WD ;
– 4WD Lock.
“AUTO” mode
To activate this mode, turn selector 1 to
the “AUTO” position.
Operating principle
“AUTO” mode automatically distributes
the engine torque between the front and
rear axles according to the road condi-
tions and the vehicle speed. This po-
sition optimises roadholding. Use this
mode on any type of road (dry, snow-
covered, slippery, etc.) or when towing
(trailer or caravan).
The warning light
on the instru-
ment panel will come on.
TRANSMISSION: 4-wheel drive (4WD) (1/4)
“2WD” mode
To activate this mode, turn the selec-
tor 1 to the “2WD” position. The warn-
ing light
‘ on the instrument panel
will come on.
Operating principle
The “2WD” mode uses the front wheels
only. Use this mode on dry roads with
good grip.
To deactivate this mode, turn the selec-
tor 1 to the “AUTO” position. Warning
light
‘ goes out on the instrument
panel.
Remember that driving a vehicle off-
road is very different to driving it on
the road.
To make the most of your vehicle
in an off-road situation, we recom-
mend that you are trained to drive a
4x4 (4WD) vehicle.
The safety of both you and your
passengers is your responsibility,
and depends on your skill and the
care you take when driving off-road.

2.36
TRANSMISSION: 4-wheel drive (4WD) (2/4)
This problem may be resolved by
changing the tyres. Always use four
identical tyres (same brand, profile,
etc.) and with similar wear.
In the event of excessive wheelspin, the
mechanical components may overheat.
If this happens:
– at first, the
’ warning light
comes on. “4WD Lock” mode is still
active – however, we recommend
that you stop as soon as possible to
allow the system to cool down (until
the warning light goes out);
– if the wheels still spin, the system au- tomatically switches to “2WD” mode
to protect the mechanical compo-
nents.
The message “4WD overheating” is
displayed on the instrument panel.
The mode cannot be changed while
the message is displayed.
Note: If the vehicle speed exceeds
approximately 24.8 mph (40 km/h) in
“4WD Lock” mode, the system auto-
matically switches back to “AUTO”
mode.
The
’ warning light goes out and
the
warning light comes on.
Special features of the
4-wheel drive transmission
The vehicle may make more noise when
the “AUTO” or “4WD Lock” modes are
activated. This is normal. If the system
detects a difference in the dimensions
of the front and rear wheels (eg. un-
derinflation, severe wear on an axle),
the system automatically switches to
“2WD” mode.
The message “4WD unavailable unsuit-
able tyres” is displayed on the instru-
ment panel. Drive as soon as possible
at a moderate speed to an approved
dealer.
“4WD Lock” mode
To activate this mode, turn selector 1 to
the “4WD Lock” position. The selector
the returns to the “AUTO” position. The
’ indicator light will light up on the
instrument panel.
Operating principle
“4WD Lock” mode distributes the
engine torque between the front and
rear axles in order to optimise the per-
formance capacity of the vehicle in off-
road situations. This mode should only
be used in extreme driving conditions
(mud, steep slopes, sand).
To deactivate this mode, turn selector 1
to the “4WD Lock” position again. The
warning light goes out on the instru-
ment panel.

TRANSMISSION: 4-wheel drive (4WD) (3/4)
Electronic stability program and
traction control when driving off-
road
When driving on soft ground (sand,
mud, deep snow), we recommend that
you deactivate the ESC function by
pressing the “ESC” switch.
In this case, only individual wheel brak-
ing remains active. This function ap-
plies the brake to any wheel that is slip-
ping, allowing the engine torque to be
transferred to the wheels with the most
grip. This is particularly useful when
crossing a bridge.
All the ESC functions will be reacti-
vated when the vehicle speed reaches
approximately 31 mph (50 km/h)
(24.8 mph [40 km/h] in 4WD Lock
mode), when the engine is restarted
or when the “ESC” switch is pressed
again.Operating faults
If the system detects an operating fault,
it automatically switches to “2WD”
mode. The message “Check 4WD” is
displayed on the instrument panel, and
the
‘ and © warning lights
come on.
Drive as soon as possible at a moder-
ate speed to an approved dealer.
For certain operating faults, the system
may not be able to switch to “2WD” or
"4WD Lock” mode. “AUTO” mode re-
mains active.
Contact an approved dealer as soon as
possible.
After stopping the engine, the system
may take up to five minutes to cool
down.
If the system detects excessive wheel-
spin on the front wheels, it adapts the
engine to run in a way that reduces
wheelspin.
Anti-lock braking in
LOCK mode
When “4WD Lock” mode is active, the
ABS switches to off-road mode. In this
case, the wheels may lock intermit-
tently to achieve better grip, thus reduc-
ing braking distances on soft ground.
When this mode is active:
– the vehicle’s manoeuvrability is lim- ited during braking. This operating
mode is therefore not recommended
in very low-grip conditions (eg. ice).
– there may be some noise. This is normal, and does not indicate an op-
erating fault.

2.38
TRANSMISSION: 4-wheel drive (4WD) (4/4)
All-wheel drive system
– Irrespective of the mode selected, do not start the engine if one or mor\
e wheels are not in contact with the ground
(eg. when the vehicle is on a jack or roller bench).
– Do not turn the mode selector when cornering, reversing or if the wheels\
are spinning excessively. Only select the
“2WD”, “AUTO” or “4WD Lock” mode when the vehicle is being driven in a str\
aight line.
– Only use tyres which meet the required specifications.
– “4WD Lock” mode is exclusively reserved for driving off-road. The use of this mode in any other conditions may adversely
affect the vehicle’s manoeuvrability and damage its mechanical components.
– Always ensure tyres with identical specifications are fitted to all four\
wheels (brand, size, structure, wear etc.). Fitting tyres
of different sizes to the front and rear wheels and/or left and right wheels m\
ay have serious consequences for the tyres,
gearbox, transfer gearbox and the rear differential pinions.

ACTIVE EMERGENCY BRAKING (3/11)
Operating faults
When the system detects an operating
fault, the
warning light lights up
on the instrument panel, with the mes-
sage “Active braking disconnected”.
There are two possibilities:
– the system is temporarily disrupted (for example: radar obscured by
dirt, mud, snow etc.). In this case,
park the vehicle and switch off the
engine. Clean the detection zone of
the radar. When you next start the
engine, the warning light and the
message go out
– if this is not the case, this may arise from another cause; contact an
Approved Dealer.
Consult an approved dealer.
Press the switch 7
OK again to activate
or deactivate the function:= function activated
< function deactivated
The warning light
is displayed on
the instrument panel when the system
is deactivated. This system is reacti-
vated each time the ignition is switched
on.
Conditions for non-activation
of the system
The system cannot be activated:
– when the gear lever is in neutral;
– when the parking brake is activated;
– while cornering.
– For 4-wheel drive vehicles, when Electronic Stability Programme
(ESC) with understeer and trac-
tion control are deactivated (please
see “Electronic Stability Programme
(ESC) with understeer and trac-
tion control” above). Warning light
comes on.The system A only detects vehicles
driving in the same direction of traf-
fic. The system cannot detect mo-
torcycles because of the difficulty in
forecasting their trajectory.

2.42
ACTIVE EMERGENCY BRAKING (4/11)
Active emergency braking
This function is an additional driving aid. This function is not under any circumstances intended to replace the due\
care
and attention of the driver, who should at all times be in control of the vehicle. The triggering of this function may be
delayed or prevented when the system detects clear signs of control of t\
he vehicle by the driver (action on the steer-
ing wheel, pedals etc.).
System servicing/repairs
– In the event of an impact, the radar-camera or radar alignment may be ch\
anged, and its operation may consequently be af- fected. Deactivate the function, then consult an authorised dealer.
– Any work in the area where the radar-camera or radar are located (repai\
rs, replacements, windscreen modifications etc.) must be carried out by a qualified professional.
– Fitting accessories which may block the radar is prohibited (bull \
bars etc.).
Only an authorised dealer is qualified to service the system.
In the event of system disturbance
Some conditions can disturb or damage the operation of the system, such \
as:
– a complex environment (metal bridge, tunnel etc.);
– poor weather conditions (snow, hail, black ice etc.);
Risk of inadvertent braking.
