Seat ventilation system
The buttons are located on each door.
Seat ventilation can be activated manually with the
electronic key in starter switch positions 1 or 2, or by
the summer opening function, see page 45.
Notes:
When in operation, the seat ventilation system
consumes a large amount of electrical power. It is not
advisable to use the seat ventilator longer than
necessary.The seat ventilators may automatically switch off if too
many power consumers are switched on at the same
time or if the battery charge is low. In this case, one or
more indicator lamps will blink.
The seat ventilation switch back on again automatically
as soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to
you, the seat ventilators can be switched off.
The maximum ventilation level (level 3) is automatically
selected if the driver’s seat ventilation is activated by
the summer opening function, see page 45.

Seat belts and integrated restraint system
Your vehicle is equipped with seat belts for all seats,
emergency tensioning retractors for all outboard seat
belts, dual front airbags, side impact airbags for driver,
front and outer rear passengers, and head protective
window curtain 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 restraints 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.

With the electronic key in starter switch position 2, a
warning sounds for a short time if the driver’s seat belt
is not fastened.
Automatic comfort-fit seat belt:
An automatic comfort-fit feature for all seat belt is
activated when the electronic key in the starter switch is
turned to position 1 or 2.
The retraction force of the inertia reel is reduced,
increasing the level of seat belt comfort.
Note:
For cleaning and care of the seat belts see page 381.
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 of 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.

across the abdomen.
Tighten the lap portion to a snug fit by pulling shoulder
portion up.
