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 un-
dersteer (loss of front axle road hol-
ding).
Traction control
This system helps to limit wheelspin of
the drive wheels and to control the vehi-
cle 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 beha-
viour to be adapted to suit the dri-
ving 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 responsibi-
lity 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 operating
fault the message “CHECK ESC” and
warning light
© and  appear
on the instrument panel. In this case,
the ESC and traction control system
are deactivated.
Consult an approved dealer.

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. Operating faults
When the system detects an operating
fault the message “CHECK ABS” ap-
pears 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.

SEQUENTIAL GEARBOX (5/6)
Special circumstances
Snow mode
(depending on vehicle)
If you are driving on ground where you
are likely to skid (snow, mud, etc.),
press switch 7 and indicator light
â
on the instrument panel will come on.
Once these driving conditions no
longer apply, exit this position by
pressing switch again; the operat-
ing tell-tale goes out. Switching to snow mode selects the
gearbox automatic mode (switching to
manual deselects snow mode until au-
tomatic mode is selected again).
Snow mode is deselected every time
the engine is switched off. It will be nec-
essary to select it again.
Load position
When the vehicle is driven loaded,
press the 8
switch on the dashboard.
The indicator light
§ on the instru-
ment panel will light up.
Load mode is deselected every time
the engine is switched off. It will be nec-
essary to select it again.
Load mode may be used to equal effect
in both automatic and manual modes.
Accelerating and overtaking
– slowly depress the accelerator pedal to accelerate gradually;
– to obtain maximum vehicle per-
formance regardless of the mode
selected (automatic or manual),
quickly depress the accelerator
pedal beyond the kickdown point.
The speed with which you depress the
pedal will allow you to downshift ac-
cording to the vehicle’s capabilities.
Parking
It is possible to park in gear (for exam-
ple, on a slope):
– with the ignition on, select a gear with your foot on the brake ;
– check that a gear other than N is dis- played on the instrument panel, then
remove the ignition key;
– apply the handbrake.
To disengage the gear, switch on the
ignition without starting the engine and
shift the selector lever to neutral with
the brake pedal depressed . Check
that N is displayed on the instrument
panel.

SEQUENTIAL GEARBOX (6/6)
Bleep
– If you hold the vehicle on a slope for too long without applying the
brakes or handbrake, you will strain
the system (risk of overheating the
clutch).
In this case, an intermittent beep-
ing sound will remind you that you
should put your foot on the brake
pedal or apply the handbrake.
– Never leave the vehicle with the engine running when in gear. For
safety reasons you will hear an in-
termittent beeping sound when you
open the door if you have not shifted
into neutral or you have not switched
off the ignition or depressed the
brake pedal.
Operating faults
i
If this warning light comes on
when the vehicle is in motion , it
indicates a fault in the system. In most
cases, you may still drive the vehicle,
although it will not function perfectly.
Contact an approved dealer as soon as
possible.
Towing a vehicle with a sequential
gearbox
If the gearbox is stuck in a gear:
– switch on the ignition;
– select neutral with the brake pedal
depressed;
– check that the gearbox is in neutral (by pushing the vehicle, for exam-
ple).
If you cannot find neutral you must tow
the vehicle with the front wheels raised.
The vehicle should always be towed
with the ignition switched off.

ENGINE OIL LEVEL: general information (1/2)
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 an 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.

LEVELS (1/3)
Brake fluid
This should be checked frequently,
and immediately if you notice even the
slightest loss in braking efficiency.
The level should be read with the engine
switched off and on level ground. Level 1
It is normal for the level to drop as
the linings become worn, but it should
never drop below the
“MIN” 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.
Filling
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.
