Driving and operating155Functionality check
When the vehicle is not moving, the
electric parking brake might be
applied automatically. This is done to
check the system.
Fault
Failure mode of electric parking brake
is indicated by a control indicator j
and by a vehicle message which is
displayed in the Driver Information Centre.
Vehicle messages 3 106.
Control indicator j flashes: electric
parking brake is not fully applied or
released. When continuously
flashing, release electric parking
brake and retry applying.
Brake assist If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.
Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance
when depressing the brake pedal.Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake
pedal is released.
Hill start assist The system helps prevent unintended
movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain on for further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.
Regenerative braking
Regenerative braking generates
electrical energy resulting from
braking to charge the high voltage
battery. Regenerative power may be
limited when the high voltage battery
is fully charged.
If the selector lever is in D, energy is
recuperated when the brake pedal is
depressed.If the selector lever is in B, energy is
recuperated when the accelerator pedal is lifted.

156Driving and operatingRide control systems
Electronic Stability Control and Traction Control system
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip.
As soon as the vehicle starts to
swerve (understeer / oversteer),
engine output is reduced and the wheels are braked individually.
ESC operates in combination with the traction control system. It prevents
the driven wheels from spinning.
The traction control system is a
component of the ESC.
The traction control system improves
driving stability when necessary, regardless of the type of road surface
or tyre grip, by preventing the driven
wheels from spinning.
As soon as the driven wheels starts to spin, engine output is reduced and
the wheel spinning the most is brakedindividually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
ESC and traction control system are
operational after each engine start as soon as the control indicator b
extinguishes.
When ESC and traction control
system operate, b flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator b 3 96.
Deactivation
ESC and traction control system can
be deactivated, everytime it is
required: press a.
The LED in the button a illuminates.
A status message appears in the
Driver Information Centre when ESC
and traction control system are
deactivated.
ESC and traction control system are
reactivated by pressing the a button
again, by applying the brake or in the case that the vehicle is driven faster
than 30 mph.

Driving and operating157The LED in the button a extinguishes
when ESC and traction control
system are reactivated.
ESC and traction control system are
also reactivated the next time the
ignition is switched on.
Fault
If there is a fault in the system, the control indicator b illuminates
continuously and a message appears in the Driver Information Centre. The
system is not operational.
Have the cause of the fault remedied by a workshop.
Selective ride controlCaution
The vehicle is designed to drive
principally on-road, but it also
enables driving off-road
occasionally.
However, do not drive on terrain
where the vehicle could be
damaged due to obstacles, such
as stones among others and on
terrain with steep inclines and
poor grip.
Do not cross waters.Caution
When driving off-road, sudden
motion and manoeuvres can
cause a collision or losing control.
Selective ride control is designed to
optimise traction in low-grip
conditions (snow, mud and sand).
It adapts to the terrain by acting on the
front wheels, in doing so this saves
the weight normally associated with a more conventional four wheel drive
system.Selective ride control allows to
choose between five driving modes:
● ESC off mode 9
● standard mode 2
● snow mode 3
● mud mode 4
● sand mode 1
The several modes can be activated
by turning the control.
A LED illuminates and a status
message appears in the Driver
Information Centre to confirm the
chosen mode.

158Driving and operatingESC off mode 9
The ESC and Traction Control are
deactivated in this mode.
A LED in the button a illuminates.
ESC and Traction Control are
reactivated automatically from
30 mph or everytime the ignition is
switched on.
Standard mode 2
This mode is calibrated for a low level of wheel spin, based on the different
types of grip generally encountered in normal day to day driving.
Everytime the ignition is switched off,
the system is automatically reset to
this mode.
Snow mode 3
This mode adapts to the grip
conditions encountered by each
wheel when starting.
When advancing, the system
optimises wheel spin to guarantee the best acceleration based on theavailable traction. Recommended in
cases of deep snow and steep
inclines.
This mode is active up to a speed of
30 mph.
Mud mode 4
This mode allows considerable wheel
spin at start-up for the wheel with the
least grip, this removes mud and re- establishes traction.
Simultaneously, the wheel with the
most grip is provided with the most
torque possible.
This mode is active up to a speed of 50 mph.
Sand mode 1
This mode allows a small amount of
simultaneous wheel spin on the two
drive wheels, enabling the vehicle to
advance and reduce the risk of
sinking.
This mode is active up to a speed of
75 mph.Caution
Do not use the other modes on
sand as the vehicle may become
stuck.
Sport mode
Sport mode adapts the settings of
some vehicle systems to a sportier
driving style.
Activation
Press SPORT when engine is
running.
