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.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.
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 deacti-
vated.
Consult an approved dealer.

Regenerative braking system
When braking, the regenerative brak-
ing system can convert the energy pro-
duced by the vehicle deceleration into
electric energy.
This will recharge the 400V traction bat-
tery and gain greater vehicle range.Operating faults

AIR IONIZER
Selecting the operating mode
Air conditioning in operation, on the dis-
play A, select “Menu”, “Vehicle”, “Care”
then “Ioniser ”.
Select one of the two modes or stop dif-
fusion:
– CLEAN : helps to reduce bacteria and allergenic particles present in
the air;
– RELAX: provides a clean and relax- ing driving environment by emitting
ions;
– Stop (stop diffusion).
Activating the ioniser in CLEAN
mode at each engine start-up
To activate CLEAN mode at each
engine start-up, check the line “Start
ioniser at each vehicle start” and con-
firm.
NB:
– if the fan control is set to position 0 (stop), activating the ioniser at each
engine start-up will automatically op-
erate the fan for at least around
10 seconds.
– if the air distribution setting does not feed air to the central air vents, the
ioniser is not activated.
Do not close the vents while the ion-
iser is activated. This enables a uni-
form distribution of ions.

AIR CONDITIONING: information and operating instructions (1/2)
Do not open the refriger-
ant fluid circuit. The fluid
may damage eyes or skin.
Advice on use
In some situations, (air conditioning
off, air recirculation activated, ventila-
tion speed at zero or low, etc.) you may
notice that condensation starts to form
on the windows and windscreen.
If there is condensation, use the “Clear
View” function to remove it, then use
the air conditioning in automatic mode
to stop it forming again.
Maintenance
Refer to the Maintenance Document
for your vehicle for the inspection fre-
quency.
Range
It is normal to notice an increase in
energy usage when the air conditioning
is operating. Recommendations to limit energy
consumption and maintain the
range of the vehicle:
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.
Favour:
– before departure, the use of the air-
conditioning programming or remote
activation. Please refer to the infor-
mation on “Air-conditioning: pro-
gramming” and “Air-conditioning:
remote activation” in Section 2);
– during your journeys, using ECO mode. Please see information about
“ECO mode function” in Section 2.
Operating faults
As a general rule, contact your ap-
proved dealer in the event of an oper-
ating fault.
– Reduction in de-icing, demisting
or air conditioning performance.
This may be caused by the passen-
ger compartment filter cartridge be-
coming clogged.
– No hot or cold air is being pro-
duced. Check that the controls are
set correctly and that the fuses are
sound. Otherwise, switch off the
system.
Presence of water under the
vehicle
After prolonged use of the air condi-
tioning system, it is normal for water
to be present under the vehicle. This is
caused by condensation.
Vehicles equipped with
modeECO
Once activated, ECO mode may
reduce air conditioning perform-
ance. Please refer to the informa-
tion on “Driving advice, Eco-driving”
in Section 2.
Use the air conditioning system reg-
ularly, even in cold weather, running
it at least once a month for approxi-
mately 5 minutes.
