Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced by
an authorized Mercedes-Benz Center.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open.

45 Getting started
Driving
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
Notify an authorized Mercedes-Benz
Center.

Turn the combination switch to the de-
sired position depending on the inten-
sity of the rain.
0Windshield wipers off
IIntermittent wiping
IINormal wiper speed
IIIFast wiper speed
Single wipe

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

Push switch in the direction of arrow1
past the resistance point.
The windshield wiper operates with
washer fluid.
iThe intermittent wiping interval is de-
pendent on wetness of windshield.
Wiping will not occur with a door open.
!Do not leave windshield wipers in inter-
mittent setting when vehicle is taken to
an automatic car wash or during wind-
shield cleaning. Wipers will operate in
the presence of water sprayed on the
windshield, and wipers may be dam-
aged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine started. Dust that accumulates on
the windshield might scratch the glass
when wiping occurs on a dry wind-
shield.
!If leaves, snow, etc. block the wind-
shield wipers, switch off the wipers.

For safety reasons, withdraw key
from starter switch. Remove block-
age.


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.

66 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 and recommended for
use by Mercedes-Benz.


Ensure that the infant or child is prop-
erly secured by a belt at all times while
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Center.
Infant and child restraint systems
Only use a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.
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 re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During seat belt retraction, a ratch-
eting sound can be heard to indicate that
the special seat belt retractor is activated.
The 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 man-
ner.

fittings for tether anchorages

seat anchors (
page 71).
Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.!The use of infant or child restraints is
required by law in all 50 states, the Dis-
trict 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 properly secured by a
lap-shoulder belt or, if so equipped, a
child restraint lower anchorage system
that complies with U.S. Federal Motor
Vehicle Safety Standards 213 and 225
and Canadian Motor Vehicle Safety
Standards 213 and 210.2.
