the shift is not executed. This can
cause a message in the Driver
Information Centre.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shift indication
The symbol  R or  S with a number
beside it is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● Special programmes automatically adapt the shifting
points when driving up inclines or
down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission control 

Driving and operating145enables the driver to select
manually first, second or third
gear for starting off.
Kickdown
Pressing down the accelerator pedal
beyond the kickdown detent will lead to maximum acceleration
independent of selected driving
mode. The transmission shifts to a
lower gear depending on engine speed.
Fault
In the event of a fault a message is
displayed in the Driver Information Centre.
Vehicle messages  3 103.
Electronic transmission control

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 unintendedmovement 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. 

Driving and operating151ESC and TC 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.
ESC 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
50 km/h or everytime the ignition is
switched on.
