0001 Solutions
The rear window
defroster has
deactivated
prematurely or cannot
be activated. The battery has not been sufficiently charged.
X
Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again. Activating/deactivating air-
recirculation mode
General notes You can deactivate the flow of fresh air if
unpleasant odors are enteringt
he vehicle
from outside. The air already inside the
vehicle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in
particular at low temperatures. Only use air-
recirculation mode briefly to prevent the
windows from fogging up.
The operation of air-recirculation mode is the
same for all control panels.
Activating/deactivating X
Turn the SmartKey to position 2in the
ignition lock (Y page 165).

i Dual-zone automatic climate control: air-
recirculation mode is automatically
activated at high outside temperatures.
3-zone automatic climate control: air-
recirculation mode is automatically
activated at high levels of pollution or at
high outside temperatures.
When air-recirculation mode is activated
automatically, the indicator lamp above the 0013
button does not light up. Outside air
is added after about 30 minutes.
X To deactivate: press the0013button.
The indicator lamp above the 0013button

heat function
General notes The residual heat function is only available in
vehicles for Canada with automatic climate
control.
It is possible to make use of the residual heat
of the engine to continue heating the vehicle
for approximately 30 minutes after the engine
has been switched off. The heating time
depends on the temperature that has been
set.

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air
vents.T his 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
outlets. 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 windshield
and the hood free of blockages, such as ice,
snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior. Setting the center air vents

Example:
R Treadwear grade: 200
R Traction grade: AA
R Temperature grade: A
All passenger car tires must conform to the
statutory safety requirements in additio nto
these grades.
i The actual values for tires are vehicle-
specifi cand may deviate from the values in
the illustration.
Treadwear The treadwea
rgrade is a comparative rating
based on the wearr ate of the tire when tested
unde rcontrolled conditions on a specified
U.S. government course. For example, a tire
graded 150 would wear one and one-half
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 conditions.
Traction G
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
! Avoid wheelspin. This can lead to damage
to the drive train.
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire's ability to stop on a wet surface as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. Atire marked C may have poor
traction performance. The safe speed on a wet, snow covered or icy
road is always lower than on dry road
surfaces.
You should pay special attention to road
conditions when temperatures are around
freezing point.
Mercedes-Benz recommends a minimum
tread depth of
000Bin(4 mm) on all four winter
tires. Observe the legally required minimum
tire tread depth (Y page 345). Winter tires can
reduce the braking distance on snow-covered
surfaces in comparison with summer tires.
The braking distance is still much further than
on surfaces that are not icy or covered with
snow. Take appropriate care when driving.
Further information on winter tires (M+S
tires) (Y page 346).
Temperature G
WARNING
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
excessive heat build-up and possible tire
failure.
The temperature grades are A(the highest),
B, and C. These represent the tire's
resistance to the generatio nofheat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to sudden
tire failure. The grade Ccorresponds to a level
of performance which all passenger car tires
must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law. 360
