Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

WARNING
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally if the side windows and the roof are
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 138).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 90). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observe the interval for replacing the filter, which is
specified in the Service Booklet
.As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. 130

Information abou
tusing
THERMOTRONIC 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 indicato rlamps above
the à and¿ buttons light up.
R In automatic mode, you can also use the
ñ button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM level is recommended.
R Set the temperature to 22 †.
R Only use the demisting function briefly until
the windscree nis clear again.
R Only use the air-recirculation mode briefly,
e.g. if there are unpleasant outside odours
or when in a tunnel. The windows could
otherwise 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.T he indicator lamp above

Points to observe before use G
WARNING
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted.
Condensation may drip from the underside of
the vehicle when cooling mode is active. This
is normal and not a sign that there is a mal-
function.
i The cooling with air dehumidification
function uses refrigerant R134a. This
refrigerant does not contain chlorofluoro-
carbons, and therefore does not damage
the ozone layer. Operating the climate control system

tem, e.g. a garage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels.
The material could otherwise ignite and set

Important safety notes
New and replaced brake pads and discs only
reach their optimum braking effec tafter sev-
eral hundred kilometres of driving. Compen-
sate for this by applying greater force to the
brake pedal. The first 1,500 km
If you treat the engine with sufficient care
from the very start, you will be rewarded with
excellent performance for the remainder of
the engine's life.
R Drive at varying vehicle speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gea ringood time, before the rev
counter needle is Ôof the way to the red
area of the rev counter.
R Do not shift down a gear manually in order
to brake.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
R The shift ranges 3,2or 1should only be
engaged when driving slowly, e.g. when
driving in mountainous terrain. After 1500 km, you may gradually accelerate
the vehicle to full road and engine speeds.
Additional running-in notes for AMG vehicles:
R
Do not drive at speeds above 140 km/h for
the first 1500 km.
R Only allow the engine to reach a maximum
engine speed of 4500 rpm briefly.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with rear axle differen-
tial lock
Your vehicle is equipped with aself-locking
differential on the rear axle. Change the oil
after a running-in period of 3000 km to
improve protection of the rear axle differen-
tial. This oil change will lengthen the service
life of the differential. Have the oil change
carried out at a qualified specialist workshop. Driving
