control
Automatic climate control The following contains instructions and rec-
ommendations to enable you to get the most
out of your THERMOTRONIC automatic cli-
mate control.
R Activate climate control using the Ãand
¿ buttons. The indicator lamps above
the à and¿ buttons light up.
R In automatic mode, you can also use the
ñ button to adjust airflow (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
R Set the temperature to 22 †.
R Only use the "Windscreen demisting" func-
tion briefly until the windscreen is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in a tunnel. The windows could oth-
erwise mist up as no fresh air is drawn into
the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above

Switching the auxiliary heating/venti-
lation on/off using the remote control General notes
Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For more information, please
contact a qualified specialist workshop.
Store the remote control for the auxiliary
heating so that the auxiliary heating cannot
be switched on unintentionally. In particular,
ensure that the remote control for the auxili-
ary heating is kept out of the reach of chil-
dren. The remote control has a maximum range of
approximately 300 metres. This range is
reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
i The optimum range can be achieved if you
hold the remote control vertically, pointing
upwards when you press one of the but-
tons.
i A battery symbol appears in the display
when the battery in the remote control is
low. Replace the remote control battery
(Y page 152).

WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.
R never cover the vents or ventilation grilles

pulling away.
i The vehicle locks centrally once you have
pulled away. The locking knobs in the doors drop down.
You can open the doors from the inside at
any time. You can also deactivate the automatic lock-
ing feature (Y page 255).
i It is only possible to shift the transmission
from position Pto the desired position if
you depress the brake pedal. If the brake
pedal is not depressed, the DIRECT SELECT
lever can still be moved, but the parking
lock remains engaged.
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot from the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll. G
WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if: R you are pulling away on a level road or a
downhill gradient
