Automatic climate control
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

Turn the SmartKey in the starter switch
to position1 or0 or remove it from the
starter switch.

Press button T (
page 186).
The indicator lamp on button comes
on.Deactivating

Press button T (
page 186).
The indicator lamp on button goes out.
The residual heat is automatically turned
off:


when the ignition is switched on


after about 30 minutes


if the battery voltage drops


if the coolant temperature is too low
i
How long the system will provide heating
depends on the coolant temperature and the
selected temperature. The blower will run at low
speed regardless of the air distribution control
setting.

switch, the door windows can be operated


until you open a door


for at least 5 minutes if no door was opened

284 OperationTires and wheelsUniform 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.

on tires are specific to each vehicle and may vary

298 OperationVehicle careYou should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible.Vehicle washingHand-wash
Do not use hot water or wash your vehicle
in direct sunlight.

Only use a mild car wash detergent,
which is recommended by
Mercedes-Benz.

Only use a soft sponge or a washing
brush.

Thoroughly spray the vehicle with a
diffused jet of water.
Direct only a very weak spray towards
the ventilation intake.

Use plenty of water and rinse the
sponge and chamois frequently.

Rinse with clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are
preferable.

To protect the filter system, switch the
automatic climate control to air
recirculation mode (
page 193).
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.
!
When washing the vehicle, fine and rigid
particles in sponges or brushes could scratch or
otherwise damage the paint. This applies to
both, hand-wash or automatic car wash.
Mercedes-Benz recommends you to have your
vehicle cleaned at an automatic car wash from
the start, preferably one without brushes, or to
use plenty of water when hand-washing your
vehicle.
Do not wash the car in direct sunlight and when
the body surface is hot.
In the winter, remove salt residue quickly and
thoroughly.
!
Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you may scratch or damage the paint.
!
Do not clean your vehicle in an automatic
touchless car wash which uses caustic spray.
Otherwise, the caustic spray will damage the
paint or ornamental moldings.
Do not choose final hot-wax conservation when
taking the vehicle to an automatic car wash.
