seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the seat belt is properly
positioned on the body.GWarning!
Never let more people ride in the vehicle than
there are seat belts available. Make sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at a
time.
GWarning!
Damaged seat belts or seat belts that have
been subjected to stress in an accident must
be replaced. Also, the seat belt anchoring
points must be checked.
Only use seat belts which have been approved
by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to their failure to activate when
necessary.
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.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
Proper use of seat belts
GWarning!
USE SEAT BELTS PROPERLY
R Seat belts can only protect when used
properly. Never wear seat belts in any other
way than as described in this section, as
that could result in serious injuries in case
of an accident.
R Each occupant should wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, driver side knee
bag, front passenger front air bag, side
impact air bags, pelvis air bags, window
curtain air bags for side windows),
Emergency Tensioning Devices (ETDs),
seat belt force limiters, and front seat knee
bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver’s side knee bag, and ETDs) and side
(side impact air bags, pelvis air bags,
window curtain air bags, and ETDs) impacts
which exceed preset deployment
thresholds.
R Never wear the shoulder belt under your
arm, against your neck or off your shoulder.
In a frontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck. Never pass the shoulder
portion of the seat belt under your arm.
R Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
a crash.
R Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
R Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
R Never use a seat belt for more than one
person at a time. Do not fasten a seat beltOccupant safety49Safety and security204_AKB; 5; 23, en-USd2ureepe,Version: 2.11.8.12009-07-16T17:54:06+02:00 - Seite 49Z

Driving characteristics may be impaired.
If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.
The language setting for the multifunction
display can be changed with the audio system
(Y page 148) or with the COMAND system.
Vehicles with COMAND system: Refer to
separate operating instructions.
Activating the instrument cluster
The instrument cluster is activated when you
Ropen the driver’s door
Rswitch on the ignition
Adjusting the instrument cluster
illumination
XTo brighten illumination: Turn
dimmer : clockwise.
XTo dim illumination: Turn dimmer :
counterclockwise.
iThe instrument cluster illumination is
dimmed or brightened automatically to suit
ambient light conditions.
The instrument cluster illumination will also
be adjusted automatically when you switch
on the vehicle’s exterior lamps.
Coolant temperature gauge
The coolant temperature gauge is located on
the left side in the instrument cluster
(Y page 28).
GWarning!
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†), i.e close to the
red zone of the temperature gauge.
! Excessive coolant temperature triggers a
warning in the multifunction display.
The engine should not be operated with a
coolant temperature above 248‡ (120†),
i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not
covered by the Mercedes-Benz Limited
Warranty.
Tachometer
The red marking on the tachometer
(Y page 28) denotes excessive engine speed.
! Avoid driving at excessive engine speeds,
as it may result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
To help protect the engine, the fuel supply is
interrupted if the engine is operated within
the red marking.

control, or simply for continued use as a
hand-held remote control to operate the
respective device in other situations.
Reprogramming a single signal
transmitter button
To program a device using a signal
transmitter button previously trained, follow
these steps:
XSwitch on the ignition.XPress and hold the desired signal
transmitter button ( ;, = or ?). Do not
release the button.
Indicator lamp : will begin to flash after
20 seconds.XWithout releasing the signal transmitter
button, proceed with programming starting
with step 3.
Operation of integrated remote control
XSwitch on the ignition.XSelect and press the appropriate
integrated signal transmitter button ( ;,
= or ?) to activate the remote controlled
device.
The integrated remote control transmitter
continues to send the signal as long as the
button is pressed – up to 20 seconds.
Erasing the integrated remote control
memory
i If you sell your vehicle, erase the codes of
all three channels.
XSwitch on the ignition.XSimultaneously press and hold outer signal
transmitter buttons ; and ?, for
approximately 20 seconds, until indicator
lamp : flashes rapidly. Do not hold for
longer than 30 seconds.
The codes of all three channels are erased.Programming tips
If you are having difficulty programming the
integrated remote control, here are some
helpful tips:
R Check the frequency of hand-held remote
control A (typically located on the reverse
side of the remote). The integrated remote
control is compatible with radio-frequency
devices operating between 280-390 MHz.
R Put a new battery in hand-held remote
control A. This will increase the likelihood
of the hand-held remote control sending a
stronger and more accurate signal to the
integrated remote control.
R While performing step 3, hold hand-held
remote control A at different lengths and
angles from the signal transmitter button
( ; , = or ?) you are programming.
Attempt varying angles at the distance of 2
to 12 inches (5 to 30 cm) away or the same
angle at varying distances.
R If another hand-held remote control is
available for the same device, try the
programming steps again using that other
hand-held remote control. Make sure new
batteries are in the hand-held remote
control before beginning the procedure.
R Straighten the antenna wire from the
garage door opener assembly. This may
help improve transmitting and/or receiving
signals.
i Certain types of garage door openers are
incompatible with the integrated remote
control. If you should experience further
difficulties with programming the
integrated remote control, contact an
authorized Mercedes-Benz Center, or call
the Mercedes-Benz Customer Assistance
Center (USA only) at
1-800-FOR-MERCedes (1-800-367-6372),
or the HomeLink ®
Hotline (USA only) at
1-800-355-3515, or the Customer Service
(Canada only) at 1-800-387-0100.
