Setting the rear-compartment air
vents
Rear air vents (example: right-hand side of vehi-
cle)
:
Thumbwheel for vertical adjustment of the
airflow and air quantity control
; Thumbwheel for horizontal adjustment of
the airflow
The air vents can only be adjusted on vehicles
with rear-compartment air conditioning.
Vehicles with rear-compartment air condition-
ing: in heating mode, the air in the rear com-
partment is automatically distributed in the
footwells and roof area after the coolant has
reached the required temperature. In cooling
mode, in the initial phase the air is distributed
in the footwells and roof area of the hot vehi-
cle, and subsequently only in the roof area.
X To open: turn thumbwheel : of the rear air
vent to the center position.
X To close: turn thumbwheel : to the upper
or lower end position. Adjusting the air vents

is an increased danger of skidding and acci-
dents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again. The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
As a rule, you may only apply the parking
brake when the vehicle is stationary.
X To apply the parking brake: depress park-
ing brake pedal ; firmly.
The red F (only USA) or J (only Can-
ada) indicator lamp in the instrument cluster
lights up if the engine is running.
X To release the parking brake: depress the
brake pedal and keep it depressed.
X Pull release handle :.
The parking brake is released abruptly. The
red F (only USA) or J (only Canada)
indicator lamp in the instrument cluster
goes out.
Exceptionally, if the service brake fails, the
parking brake can be used to brake the vehicle
in an emergency.
X Emergency braking: pull release handle :
and gradually depress parking brake
pedal ;. Switching off the engine
Important safety notes G
WARNING
The automatic transmission switches to neu-
tral position N when you switch off the
engine. The vehicle may roll away. There is a
risk of an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked
vehicle from rolling away by applying the
parking brake.
! If the coolant temperature is very high, e.g.
after driving on hilly roads, leave the engine
running at idle speed for about
two minutes
before turning it off.
This allows the coolant temperature to
return to normal.
Vehicles with automatic transmission X
Stop the vehicle.
X Shift the transmission to position j.
X Apply the parking brake.
X Turn the key to position u in the ignition
lock and remove it.
The immobilizer is activated.
If you switch the engine off with the trans-
mission in position k or h, the automatic
transmission shifts to i automatically.
If you then open one of the front doors or
remove the key, the automatic transmission
automatically shifts to j.
If you shift the automatic transmission to
i before switching off the engine, the
automatic transmission remains in i even
if a front door is opened.
X Secure the vehicle to prevent it from rolling
away
