Automatic climate control* (Canada only)
Deactivating
Press buttone (page 185).
The indicator lamp on the button goes
out.
Air conditioning
The cooling function, only operational
when the engine is running, cools the vehi-
cle interior down to the selected tempera-
ture. The cooling function also
dehumidifies the air in the vehicle interior,
thus preventing the windows from fogging
up.
Warning!G
Never operate the side windows and the
tilt/sliding sunroof if there is the possibility
of anyone being harmed by the closing pro-
cedure.
In the event that the closing procedure
causes potential danger, the closing of the
side windows can be immediately halted by
pressing or pulling the respective window
switch. The closing of the tilt/sliding
sunroof can be immediately halted by
moving the tilt/sliding sunroof switch in the
overhead control panel in any direction.
The closing of the side windows and
tilt/sliding sunroof can be reversed by again
pressing and holding the buttone.
i
Press and hold buttone for approx.
2 seconds. The side windows and or
tilt/sliding sunroof will return to their
previous position. You can release
buttone once the opening proce-
dure has begun. The windows and
tilt/sliding sunroof continue opening
until they have reached their previous
position.
A window or tilt/sliding sunroof will
only return to its previous position if it
has not been moved to another posi-
tion using the respective window
switch or tilt/sliding sunroof switch af-
ter it was closed with buttone. A
window or tilt/sliding sunroof that was
moved will remain in its current posi-
tion if buttone is used to re-open
the remaining windows or tilt/sliding
sunroof.
i
Condensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
Warning!G
If you turn off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog
up more quickly. Window fogging may
impair visibility and endanger you and
others.

195 Controls in detail
Automatic climate control* (Canada only)
Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the automatic
climate control system. The air in the
vehicle will then no longer be cooled or
dehumidified.
Press button9 (page 185).
The indicator lamp on the button goes
out.
The cooling function switches off after
a short delay.
Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condi-
tioning.
Press button9 (page 185) again.
The indicator lamp on the button
comes on.The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
Residual heat and ventilation
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.Activating
Switch off the ignition (page 33).
Press button9 (page 185).
The indicator lamp on the button
comes on.
!
If the air conditioning cannot be turned
on again, this indicates that the air
conditioning is losing refrigerant. The
compressor has turned itself off.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.
i
How long the system will provide
heating depends on

the coolant temperature

the temperature set by the operator
The blower will run at speed setting 1
regardless of the air distribution
control setting.

window and open it slightly.
If the window encounters an obstruction
that blocks its path in a circumstance where
you are closing the window by pulling and
holding the switch, by pressing and holding
button‹ on the SmartKey, or by press-

Tires and wheels
Uniform Tire Quality Grading Standards
(U.S. vehicles)
Tire manufacturers are required to grade
tires based on three performance
factors: treadwear, traction and
temperature resistance.
1Treadwear
2Traction
3Temperature resistanceQuality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example:
All passenger car tires must conform to
federal safety requirements in addition to
these grades.Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1
1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly
from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.

data on tires is specific to each vehicle
