Occupant safety
Warning!G
Modifications to or work improperly con-
ducted on restraint systems (such as seat
belts and anchors, emergency tensioning
devices, seat belt force limiters or air bags)
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems no longer function-
ing as intended.
Air bags or emergency tensioning devices,
for example, could deploy inadvertently or
fail to deploy in accidents although the
deceleration threshold for air bag deploy-
ment is exceeded. Therefore, never modify
the restraint systems. Do not tamper with
electronic components or their software.
Warning!G
In the event that the 1 indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend that you contact an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not deploy when needed in an accident,
which could result in serious personal or
fatal injury, or it might deploy unexpectedly
and unnecessarily which could also result in
injury.
In addition, improper repair work on the SRS
creates a risk of rendering the SRS inopera-
tive or causing unintended air bag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians. Con-
tact an authorized Mercedes-Benz Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.

64 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, 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 Emergency Tensioning
Devices (ETDs) are designed to function
on a one-time-only basis. An air bag or
ETD that was activated must be
replaced.
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, outboard sides of the front seat
backrests, door trim panels, 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,
purses, umbrellas, etc.).
Air bag system components will be hot
after an air bag has inflated. Do not
touch.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.

Driving abroad
Abroad, there is an extensive
Mercedes-Benz service network at your
disposal. If you plan to drive into areas
which are not listed in the index of your
Mercedes-Benz Center directory, you
should request pertinent information from
an authorized Mercedes-Benz Center.Control and operation of radio

!Do not drive through flooded areas or water
of unknown depth. Before driving through water,
determine its depth. Never accelerate before
driving into water. The bow wave could force
water into the engine and auxiliary equipment,
thus damaging them.
If you must drive through standing water, drive
slowly to prevent water from entering the pas-
senger compartment or the engine compart-
ment. Water in these areas could cause damage
to electrical components or wiring of the engine
or transmission, or could result in water being in-
gested by the engine through the air intake caus-
ing severe internal engine damage. Any such
damage is not covered by the Mercedes-Benz
Limited Warranty.
Warning!G
Always fasten items being carried as
securely as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The trunk is the preferred place to carry
objects.
Warning!G
Please do not forget that your primary
responsibility is to drive the vehicle safely.
Only operate the radio or telephone
1 if road,
weather and traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
