!Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions,
always operate the windshield wipers with
windshield washer fluid (
page 58).
!If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off
immediately.

For safety reasons, stop the vehicle in a safe
location, turn off the engine and remove the
SmartKey from the starter switch before
attempting to remove any blockage.

Remove blockage.

Turn the windshield wipers on again.
If the windshield wipers fail to function at all with

68 Safety and Security
Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
air bagiAir bags are designed to activate only in
certain frontal impacts (front air bags, knee
bags) and in side impacts (head-thorax air bags)
which exceed preset thresholds. Only during
these events will they provide their supplemental
protection.
The driver and passenger should always wear
their seat belts. Otherwise it is not possible for
the air bags to provide their supplemental
protection.
In case of other types of impacts and impacts
below air bag deployment thresholds, air bags
will not deploy. The driver and passenger will
then be protected to the extent possible by a
properly fastened seat belt. A properly fastened
seat belt is also needed to provide the best
possible protection in a rollover.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your
passenger that you replace deployed air bags
and repair any malfunctioning air bags to make
sure that the vehicle will continue to provide
supplemental crash protection for occupants.
Warning!G

Damaged seat belts or seat belts that
were highly stressed in an accident
must be replaced and their anchoring
points must also be checked. Only use
seat belts installed or supplied by an
authorized Mercedes-Benz Center.

Air bags and Emergency Tensioning
Devices (ETDs) contain Perchlorate
material, which may require special han-
dling and regard for the environment.
Check with your local government’s
disposal guidelines. California residents,
see http://www.dtsc.ca.gov/Hazard-
ousWaste/Perchlorate/index.cfm.

Air bags and Emergency Tensioning
Devices (ETDs) are designed to function
on a one-time-only basis. An air bag or
ETD that has deployed must be re-
placed.

Do not pass seat belts over sharp edges.
They could tear.

Do not make any modification that could
change the effectiveness of the seat
belts.

No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or
removing any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, passenger front air bag
cover, door frame trims, or door trim
panels, and installation of additional
electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).

Do not bleach or dye seat belts as this
may severely weaken them. In a crash,
they may not be able to provide ade-
quate protection.

Air bag system components will be hot
after an air bag has inflated. Do not
touch.

80 Safety and Security
Occupant safety
Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
The passenger lap-shoulder belt has a
special seat belt retractor for secure fas-
tening of child restraints.
To fasten a child restraint follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The seat belt is now locked. Push
down on child restraint to take up any
slack.
To deactivate, release seat belt buckle and
let seat belt retract completely.
The seat belt can again be used in the
usual manner.The use of infant or child restraints is re-
quired by law in all 50 states, the District of
Columbia, the U.S. territories, and all
Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system which is properly secured
by a lap-shoulder belt and that complies
with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213
and 210.2.Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned on these
parts.
If children open a door, they could

injure other persons

get out of the car and injure themselves
or be injured by following traffic
Do not carry heavy or hard objects in the
passenger compartment unless they are
firmly secured in place.
For more information, please refer to the
“Useful features” section (
page 253)
through (
page 255).
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of

strong braking maneuvers

sudden changes of direction

an accident
Warning!G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.

Tips on handling CDs

Handle CDs carefully to prevent
interference 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
sunlight.MP3
The CD changer* can play audio CDs as
well as CDs with MP3 files.
Information on MP3 data carriersCompatible MP3 data carriers
The CD changer can read the following
data carriers in MP3 mode:

CD-DA

CD-R

CD-RW
Compatible file systems and compres-
sion methods
Use Romeo or Joliet. Depending on file
format used, up to 128 characters are
possible.
The following compression methods are
compatible:

MP3

WMA

WAV
iCD media, CD burning software and CD
writers are available in great variety. Due to
this variety, it cannot be guaranteed that the
CD changer will be able to play every
user-written CD.
The burning process can lead to data errors and
aging of the medium may result in data loss.
Therefore, the CD changer may be restricted in
its ability to play MP3 data carriers; it may play
them with reduced sound quality, or it may not
be able to play them at all.
Problems may be encountered during playback
of user-written CDs with a storage capacity of
more than 700 MB. These CDs do not meet valid
standards as of this printing.
