Seat heating
GWARNING
Repeatedly switching on the seat heating can
cause the seat cushion and backrest pads to
become very hot. The health of persons with
limited temperature sensitivity or a limited
ability to react to high temperatures may be
affected or they may even suffer burn-like
injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.
!When you leave your seat, do not place any-
thing on the seat and switch off the seat heat-
ing. Do not switch the seat heating on when
the seat is not occupied, e.g. when driving
without a front passenger. The seat heating
may otherwise overheat, causing damage to
the seat.
The three red indicator lamps in the cbutton
show the activated heating level 1to 3.
The system automatically switches down from
level 3to level 2after approximately
five minutes.
The system automatically switches down from
level 2to level 1after approximately
ten minutes. At level
1, the seat heating remains in continu-
ous operation.
XMake sure that the key is in position 1or 2in
the ignition lock.
XTo switch on: press thecbutton repeat-
edly until the desired heating level has been
set.
XTo switch off: press thecbutton repeat-
edly until all indicator lamps go out.
If the indicator lamps of the current heating level
in the cbutton flash, the seat heating has
switched off automatically. In this case, too
many electrical consumers are switched on or
the battery charge is not sufficient. The seat
heating will automatically switch back to the
current heating level when enough on-board
voltage is available again.
Steering wheel
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
If the steering wheel is unlocked while the
vehicle is in motion, it could change position
unexpectedly. This could cause you to lose
control of the vehicle. There is a risk of an
accident.
Before starting off, make sure the steering
wheel is locked. Never unlock the steering
wheel while the vehicle is in motion.
GWARNING
Children could injure themselves if they
adjust the steering wheel. There is a risk of
injury.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 27).
Overview of climate control systems
Important safety notes
Observe the recommended settings on the fol-
lowing pages. Otherwise, the windows could fog
up.
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
iVentilate the vehicle for a brief period during
warm weather. In order to cool the vehicle
more rapidly, switch climate control to air-
recirculation mode briefly. This will speed up
the cooling process and the desired interior
temperature will be reached more quickly.
iThe integrated filter can filter out most par-
ticles of dust and completely filters out pollen.
A clogged filter reduces the airflow into the
vehicle interior. For this reason, you should
always observe the interval for replacing the
filter, which is specified in the Maintenance
Booklet. As it depends on environmental con-
ditions, e.g. heavy air pollution, the interval
may be shorter than that stated in the Main-
tenance Booklet.

Information on heating
Below, you can find a number of notes and rec-
ommendations to help you use the heating opti-
mally.
RSet the temperature control to the middle
level. Only change the temperature in small
increments.
If you wish to heat up the vehicle interior as
quickly as possible, set the temperature con-
trol to thezmaximum setting. When the
desired interior temperature has been reached, turn the temperature control back
down in small steps.
ROnly use the settings for defrosting the wind-
shield briefly, until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up
as no fresh air is drawn into the vehicle in air-
recirculation mode. The indicator lamp in the
h button comes on when the function is
switched on.
