not even with a CD adapter. Attempting to
play CDs with an eight cm diameter or
playing such CDs with an adapter may
cause damage to the CD drive. Such dam-
age is not covered by the Mercedes-Benz
Limited Warranty.
Should excessively high or low tempera-
tures occur while in CD changer mode*, CD TEMP
will appear in the display, and the
CD will be muted until the temperature has
reached an acceptable level for the system
to continue operation.
The single CD player and the CD changer*
play audio CDs.Tips on handling CDs


Handle CDs carefully to prevent inter-
ference during playback.


Avoid scratches, fingerprints and dust
on the CDs.


Do not write on CDs or apply any labels
or other material to them.


Clean CDs from time to time with a
commercially available cleaning cloth.
Never wipe the CD in a circular motion;
instead, wipe it in a straight line start-
ing in the center and moving outward.
Do not use solvents, anti-static sprays,
etc. for cleaning.


Replace the CD in its case after use.


Protect CDs from heat and direct sun-
light.
!If you affix stickers to the CDs, they can
become warped due to the heat that
develops in the CD drive or CD chang-
er.
In certain situations, the CDs can then
no longer be ejected and cause dam-
age to the drive. Such damage is not
covered by the Mercedes-Benz Limited
Warranty.!Your CD drive or CD changer has been
designed to play CDs which corre-
spond to the EN 60908 standard. You
can therefore only use CDs with a max-
imum thickness of 1.3 mm.
If you insert thicker data carriers, e.g.
ones that have data on both sides (one
side with DVD data, the other side with
audio data), they cannot be ejected and
will damage the drive.

Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:

Cruise control, with which the vehicle
can maintain a preset speed


Parktronic*, which serves as a parking
assistant.
For information on the BAS, ABS, and ESP
driving systems, see “Driving safety sys-
tems” (
page 84).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time.
CLK 320/CLK 55 AMG:
You can set or resume cruise control at any
speed over 20 mph (30 km/h).
CLK 500:
You can set or resume cruise control at any
speed over 25 mph (40 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever on the left-hand side of the steering
column (
page 22).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must remain at all
times responsible for the vehicle speed and
for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.

The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.


The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.


Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.
