ParkingWarning
G
Only remove the key from the ignition lock
when the vehicle is stationary, since it is not
possible to steer the vehicle with the key re-
moved.
Always apply the handbrake after parking
the vehicle.
Never leave children unsupervised in the ve-
hicle. They could release the handbrake.
This could lead to a serious or fatal accident.
Warning
G
Always switch off the engine and apply the
handbrake before leaving the vehicle.
The vehicle could roll away if it is not
secured.
On uphill or downhill gradients steeper than
15%:
\4apply the handbrake
\4secure an unloaded vehicle by chocking
the front axle (\2page 303)
\4secure a loaded vehicle by, for example,
chocking the rear axle (\2page 303)!
CAUTION
Whenever you park the vehicle, always
remove the key to prevent the battery
from excessively discharging.
For vehicles which are out of use for ex-
tended periods and have a battery iso-
lating switch*, switch off the electrical
system (\2page 197).
Warning
G
Make sure that the exhaust system does not
come into contact with highly flammable
materials, e.g. dry grass or gasoline. The
flammable material could otherwise ignite
and set vehicle components on fire.Warning
G
Regulations in some countries require the
parking lamps to be switched on to illumi-
nate the vehicle for other road users if
parked on a public road at night. In built-up
areas, night reflectors can also be used.
Observe legal requirements.

Stopping the engine
\1Apply handbrake (\2page 115).
\1Move selector lever to P.
\1Turn key to position 0 (\2page 67) in
the ignition lock and remove it.
The immobilizer is activated.\1Secure the vehicle at the front axle if
unloaded and at the rear axle if loaded,
e.g. using a chock (\2page 303).
Drinking and drivingSteering
!
CAUTION
If the coolant temperature is raised,
e.g. following driving in mountainous
terrain, run the engine at idling speed
for a further 1 or 2 minutes before you
switch off the engine. This allows the
coolant temperature to return to nor-
mal again.
iWhen parking on steep uphill or down-
hill gradients, turn the front wheels to-
wards the curb.iYou can only remove the key from the
ignition lock when the selector lever is
in positionP.
General driving tipsWarning
G
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment. The possibility of a serious or
even fatal accident is sharply increased
when you drink or take drugs and drive.
Never drink or take drugs and drive or allow
anyone to drive after drinking or taking
drugs.
Warning
G
There is no power-steering assistance when
the engine is not running.
You will need to use significantly more force
to steer and could therefore lose control of
the vehicle and cause an accident.
Never switch off the engine while driving.!
CAUTION
Do not hold the steering wheel in its
end positions for longer than neces-
sary (e.g. when turning or maneuver-
ing).
The hydraulic pump can be damaged
by the increased temperature of the
hydraulic fluid.

The automatic transmission adapts to your
individual driving style by continuously ad-
justing its shift points. These shift point ad-
justments take into account the current
operating and driving conditions.If the operating or driving conditions
change, the automatic transmission reacts
by adjusting the gearshift program.
The individual gears are selected automat-
ically. The gear selected depends on:
\4the selector lever position in shift rang-
es D, 4, 3, 2 and 1 (\2page 123)
\4the position of the accelerator pedal
(\2page 123)
\4the road speed

CAUTION
Vehicles with rain sensor*:
Switch off the windshield wipers in dry
weather conditions, otherwise dirt on
the surface of the rain sensor or optical
effects can cause inadvertent wiper
sweeps. This could damage the wiper
blades or scratch the windshield.
iCanada only:
The speed of the windshield wipers is
automatically reduced if the vehicle
comes to a halt with the windshield
wipers switched on.
For example, if you have selected
speedII and stop the vehicle,the wipers
wipe at intermittent speed until you pull
away again. The wipe intervals are long-
er in intermittent mode.
Vehicles with rain sensor*:
You can use speedI as the universal
speed. The rain sensor adjusts the wip-
ing frequency according to how heavy
the rain is. If you stop the vehicle,
speedsIII andII are automatically
switched down to speedI.
The original speed of the windshield
wipers is resumed when you drive fast-
er than 5 mph (8 km / h) again.
