iTo signal minor directional changes such as
changing lanes, press combination switch only
to point of resistance and release. The corre-
sponding turn signals will flash three times.!Do not operate the wipers when the wind-
shield is dry. Dust that accumulates on a wind-
shield might scratch the glass and/or damage
the wiper blades when wiping occurs on a dry
windshield. If it is necessary to operate the wip-
ers in dry weather conditions, always operate
the wipers with washer fluid (
page 57).
!If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.

For safety reasons, stop the vehicle in a safe
location

turn off the engine by turning the
SmartKey to position0 and withdraw
SmartKey from starter switch
or

turn off the engine by pressing the
KEYLESS-GO* start/stop button and
open the driver’s door (with the driver’s
door open, starter switch is in
position0, same as with SmartKey re-
moved from starter switch)
before attempting to remove any blockage.

Remove blockage.

Turn the windshield wipers on again.
!If windshield wipers fail to function at all in
combination switch positionU or V,

set the combination switch to the next high-
est wiper speed

have the windshield wipers checked at the
nearest authorized Mercedes-Benz Center

Intermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.Intermittent wiping interval is dependent
on wetness of windshield.
Turn the combination switch to
positionU or V.
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.Single wipe
Press the combination switch briefly in
direction of arrow1 (
page 56) to
the resistance point.
The windshield wipers wipe one time
without washer fluid.
Wiping with washer fluid
Push the combination switch in direc-
tion of arrow1 (
page 56) past the
resistance point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Washer system and
headlamp cleaning system*”
(
page 292).
!Do not leave windshield wipers in
intermittent setting when the vehicle is taken to
an automatic car wash or during windshield
cleaning. Windshield wipers will operate in the
presence of water sprayed on the windshield,
and windshield wipers may be damaged as a re-
sult.
!If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.
iIntermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or out
of the vehicle from being sprayed.
Intermittent wiping will be continued when

all doors are closed
and

the gear selector lever is in positionD orR
or

the wiper setting is changed using the com-
bination switch
iTo prevent smears on the windshield or
noisy/chattering wiper blades, wipe with washer
fluid every now and then even when it is raining.

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 cer-
tain frontal impacts (front air bags, driver-side
knee bag), side impacts (side impact and window
curtain air bags) which exceed preset thresholds
and in certain rollovers (window curtain
air bags). Only during these events will they pro-
vide 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 pro-
tection.
In case of other types of impacts and impacts be-
low air bag deployment thresholds, air bags will
not be deployed. 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 pro-
tection 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 pas-
sengers that you replace deployed air bags and
repair any malfunctioning air bags to make sure
that the vehicle will continue to provide supple-
mental 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. Use only
seat belts installed or supplied by an au-
thorized Mercedes-Benz Center.

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

Air bags and Emergency Tensioning De-
vices (ETDs) are designed to function on
a one-time-only basis. An air bag or ETD
that was activated must be replaced.

No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges etc. over the steering
wheel hub, front passenger front air bag
cover, outboard sides of the front seat
backrests, door trim panels, or door
frame trims, and installation of addition-
al 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 pass seat belts over sharp edges.
They could tear.

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

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.

82 Safety and Security
Occupant safety
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child.
Make sure that the infant or child is
properly secured at all times while the
vehicle is in motion.
Infant and child restraint seats and
information on choosing an appropriate
restraint system can be obtained from any
Mercedes-Benz Center.Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening 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.
Warning!G
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system. The children could

injure themselves on parts of the vehicle

be seriously or fatally injured through
exposure to extreme heat or cold
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 or cargo compartment unless
they are firmly secured in place. For more in-
formation, see “Loading” (
page 238) and
“Useful features” (
page 243).
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
