To signal minor directional changes, such as
changing lanes, press combination switch to
point of resistance only and release. The corre-
sponding turn signals will flash three times.
!
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
wipers in dry weather conditions, always operate
the windshield wipers with windshield washer
fluid (page 53).
!
If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off
immediately.


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


The hood must be opened (
page 250) be-
fore folding the wiper arms away from the
windshield. You could otherwise damage the
hood and/or the wiper arm.


Remove the blockage.


Turn the windshield wipers on again.If windshield wipers fail to function at all in
switch positionI,


set the combination switch to the next
highest wiper speed


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

53 Getting started
Driving
Intermittent wiping
The intermittent wiping interval is depen-
dent on the wetness of the windshield. 
Turn the combination switch in direc-
tion of arrow 2 to positionI.
After the initial wipe, pauses between
wipes are controlled by the rain sensor.Single wipe

Press combination switch briefly in
direction of arrow1 to the resistance
point.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid

Press combination switch in direction
of arrow1 past the resistance point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system”
(
page 257).
!
Do not leave windshield wipers on an
intermittent setting when the vehicle is taken to
an automatic car wash or during windshield
cleaning. Wipers will operate in the presence of
water sprayed on the windshield, and wipers
may be damaged as a result.
!
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.
i
Intermittent 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 drive positionD or reverse gearR
or


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

64 Safety and SecurityOccupant safety
Safety guidelines for the seat belt,
Emergency Tensioning Device (ETD)
and air bag
i
Air bags are designed to activate only in cer-
tain frontal impacts (front air bags, knee air
bags) and side impacts (head-thorax air bags)
which exceed preset thresholds. Only during
these types of impacts 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 cases 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 pos-
sible 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 pas-
senger that you replace deployed air bags and
repair any malfunctioning air bags to ensure 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 ETDs are designed to func-
tion on a one-time-only basis. An air bag
or ETD that was activated must be
replaced.


Air bags and ETDs contain perchlorate
material, which may require special han-
dling and regard for the environment.
Check with your local government’s dis-
posal guidelines. California residents,
see www.dtsc.ca.gov/Hazardous-
Waste/Perchlorate/index.cfm.


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
adequate protection.


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 cov-
er, door frame trims, or door trim pan-
els, 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,
purses, umbrellas, etc.).


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

76 Safety and SecurityOccupant safetyChildren 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 the infant or child is proper-
ly 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.
The passenger lap-shoulder belt has a
special seat belt retractor 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
excessive 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 compartment unless they are
firmly secured in place.
For more information, please refer to the
“Useful features” section (
page 209)
through (
page 210).
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of


strong braking maneuvers


sudden changes of direction
