When in operation, the seat heater consumes a large
amount of electrical power. It is not advisable to use the
seat heater longer than necessary.
The seat heaters may automatically switch off if too
many power consumers are switched on at the same
time, or if the battery charge is low. When this occurs,
the indicator lamps in the switch will blink for
approximately 30 seconds.
Within this time the seat heaters will switch on again
automatically as soon as sufficient voltage is available.
After approximately 30 seconds without sufficient
voltage the seat heaters switch off (indicator lamps go
out).

Seat belts and integrated restraint system
Your vehicle is equipped with seat belts for all seats,
emergency tensioning retractors for front and second
row outboard seat belts, dual front airbags and door
mounted side impact airbags. Their protective functions
are designed to complement one another.
Seat belts
Important!
Laws in most states and all Canadian provinces require
seat belt use.
All states and provinces require use of child restraints
that comply with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
All child restraint systems are designed to be secured in
vehicle seats by lap belts or the lap belt portion of a lap-
shoulder belt.
For your safety and that of your passengers we strongly
recommend their use.
Wa r n i n g !
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
TM compatible child seat,
which operates with the BabySmart
TM system
installed in the vehicle to deactivate the passenger
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury will result.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.

For cleaning and care of the seat belts, see page 302.
Seat belt nonusage warning system
After starting the engine, a warning sounds and the seat
belt warning lamp< remains illuminated for
approximately 6 seconds if the driver’s seat belt is not
fastened.
Wa r n i n g !
Never ride in a moving vehicle with the backrest
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.
Wa r n i n g !
Failure to wear and properly fasten and position
your seat belt greatly increases your risk of
injuries and their likely severity in an accident.
You and your passengers should always wear seat
belts.If you are ever in an accident, your injuries can be
considerably more severe without your seat belt
properly buckled. Without your seat belt buckled,
you are much more likely to hit the interior of the
vehicle or be ejected from it. You can be seriously
injured or killed.In the same crash, the possibility for injury or
death is lessened if you are wearing your seat belt.Wa r n i n g !
Never let more people ride in the vehicle than there
are seat belts available. Be sure everyone riding in
the vehicle is correctly restrained with a separate
seat belt.

Operation
The inertia reel stops the belt from unwinding during
sudden vehicle stops or when quickly pulling on the
belt. The locking function of the reel may be checked by
quickly pulling out the belt.
Unfastening of seat belts

Wa r n i n g !
USE SEAT BELTS PROPERLY.• Seat belts can only work 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.• 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 airbag, front passenger airbag, front
and rear door mounted side impact airbags),
“ETR” (seat belt emergency tensioning
retractors for the outboard passenger seats
[except in the optional 3rd row seats]), and
front seat knee bolsters. The system is
designed to enhance the protection offered to
properly belted occupants in certain frontal
(front airbags) and side (side impact airbags)
impacts which exceed preset deployment
thresholds.
