Driving
The handbrake should be applied firmly to
pr ev
ent
the vehicle from accidentally rolling
away.
Always apply the handbrake when you leave
your vehicle and when you park.
Applying the handbrake
– Pull the handbrake lever up firmly
›››
Fig. 196.
Releasing the handbrake
– Pull the lever up slightly and press the re-
lea

se knob in the direction of the arrow
››› Fig. 196 and guide the handbrake lever
down fully ››› .
A lw
a

ys pull the handbrake all the way up, so
there is less risk of driving off with it still en-
gaged ››› .
The h andbr
ak

e warning lamp  lights up
when the handbrake is applied and the igni-
tion switched on. The warning lamp turns off
when the handbrake is released.
If you drive faster than 6 km/h (4 mph) with
the handbrake on, the following message*
will appear on the instrument panel: HAND-
BRAKE ON. You will also hear an audible
warning. WARNING
● Never u se the h

andbrake to stop the vehi-
cle when it is in motion. The braking distance is considerably longer, because braking is
only
ap

plied to the rear wheels. Risk of acci-
dent!
● If the handbrake is only partially released,
this w
ill cause the rear brakes to overheat,
which can impair the function of the brake
system and could lead to an accident. This al-
so causes premature wear on the rear brake
pads. CAUTION
Always apply the handbrake before you leave
the vehic

le. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
p
lied when the
v

ehicle is parked.
Always note the following points when park-
ing the vehicle: – Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition. T

urn the steering wheel
slightly to engage the steering lock.
– Never leave a vehicle key in the vehicle. Additional notes on parking the vehicle on
gradient

s:
Turn the steering wheel so that the vehicle
rolls against the kerb if it started to roll.
● If the vehicle is parked facing downhil
l,
turn the front wheels so that they point to-
wards the kerb .
● If the vehicle is parked facing uphill
, turn
the front wheels so that they point away from
the kerb.
● Secure the vehicle as usual by applying the
handbrak
e firmly and putting it in 1st gear. WARNING
● Tak e me

asures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
coul
d ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehic
le when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They cou
ld set the vehicle in motion, for ex-
ample, by releasing the handbrake or the

lock only engages with the vehicle sta-
tionary and at speeds of up to 5 km/h
(3 mph). At speeds of over 5 km/h (3 mph)
the lever lock is automatically deactivated in
position N.
The selector lever lock is not engaged if the
selector lever is moved quickly through posi-
tion N (e.g. when shifting from R to D). This
makes it possible, for instance, to rock the
vehicle “backwards and forwards” if it is
stuck. The selector lever lock engages auto-
matically if the brake pedal is not depressed
and the lever is in position N for more than
about two seconds.
Interlock button
The interlock button on the selector lever
handle prevents the driver from inadvertently
engaging certain gears. Press the button in
to disengage the selector lever lock. The se-
lector lever positions in which the interlock
button has to be pressed are shown in the il-
lustration, highlighted in colour ››› Fig. 198.
Safety interlock for ignition key
If the vehicle does not have electronic brak-
ing, and depending on the country, once the
ignition has been turned off, the key may be
removed only if the gear selector is in posi- tion P. While the key is not in the ignition, the
selector l
ever is locked in position P. Note
● If the sel ect

or lever lock does not engage,
there is a fault. The transmission is interrup-
ted to prevent the vehicle from accidentally
moving. Follow the procedure below in order
for the selector lever lock to engage again:
–With a 6-speed gearbox: press the brake
pedal and release it again.
– With a 7-speed gearbox: press the brake
pedal. Move the selector lever to posi-
tion P or N and subsequently engage a
gear.
● Despite a gear being engaged, the vehicle
does not
move forwards or back. Proceed to
the next mode:
– When the vehicle does not move in the
required direction, the system may not
have the gear range correctly engaged.
Press the brake pedal and engage the
gear range again.
– If the vehicle still does not move in the
required direction, there is a system mal-
function. Seek specialist assistance and
have the system checked. Engaging gears with the triptonic

ible. WARNING
● Ev en w

ith four-wheel drive, you should al-
ways adjust your speed to suit the condi-
tions. Do not let the extra safety features
tempt you into taking any risks when driving.
Risk of accident!
● The braking capability of your vehicle is
limited by
the tyres' grip. It is therefore no
different from a car without four-wheel drive.
So do not be tempted to drive too fast on firm
or slippery roads just because the vehicle
still has good acceleration in these condi-
tions. Risk of accident!
● On wet roads bear in mind that the front
wheels m
ay start to “aquaplane” and lose
contact with the road if the car is driven too
fast. If this should happen, there will be no
sudden increase in engine speed to warn the
driver, as occurs with a front-wheel drive car.
For this reason you should always choose a
driving speed suitable for the road condi-
tions. Risk of accident! Driver assistance systems

ic requirements for the Start-Stop mode
● The driver door must be closed.
● The driver must have their seat belt fas-
tened. ●
The bonnet mus
t be closed.
● The engine must have reached a minimum
servic
e temperature.
● The reverse gear must not be engaged.
● The vehicle must not be on a very steep
slope. WARNING
● Never sw it

ch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehic
le is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-
