2005 MERCEDES-BENZ CLK55AMG CABRIOLET climate control

199 Controls in detail
Automatic climate control (CLK 500/CLK 55 AMG)
Residual heat and ventilation*
(available on Automatic climate control panel design A only)
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 36).

Press button°(
page 191).
The indicator lamp on the button
comes on.Deactivating

Press button°(
page 191).
The indicator lamp on the 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 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.
iHow 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.

Opening and closing the windows
The side windows are opened and closed
electrically. The switches for all the side
windows are on the driver’s door. The
switches for the respective windows are
on the front passenger door and the rear
side trim panels.

Warning!
G
When closing the windows, make sure there
is no danger of anyone being harmed by the
closing procedure.
The closing of the door windows can be im-
mediately halted by releasing the switch or,
if switch was pulled past the resistance
point and released, by either pressing or
pulling the respective switch.
The closing of the rear side windows can be
immediately halted by releasing the switch.
The door windows are equipped with the ex-
press-close and automatic reversal func-
tion. If a door window encounters an
obstruction that blocks its path in a circum-
stance where you pulled the switch past the
resistance point and released it to close the
window, the automatic reversal function will
stop the window and open it slightly.
If a door 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, by pressing
and holding the lock button (vehicles with
KEYLESS-GO*) on the door handle, by
operating the soft top switch, or by pressing
and holding the
,
button or
e
but-
ton on the climate control panel, the auto-
matic reversal function will not operate.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment can cause an accident
and/or serious personal injury.

334 OperationTires and wheelsTreadwear
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.Traction
The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades rep-
resent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.Temperature
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal Mo-
tor 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.
Warning!
G
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.
