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.

Keep the area around head restraints clear of articles
(e.g. clothing) to not obstruct the folding operation of
the head restraints.

Seat belts and integrated restraint system
Your vehicle is equipped with seat belts for all seats,
emergency tensioning retractors, dual front airbags,
side impact airbags for driver, front and 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.

BabySmart
TM airbag deactivation system
Special BabySmart
TM compatible child seats, designed

any authorized Mercedes-Benz Center are required for
use with the BabySmart
TM airbag deactivation system.
With the special child seat properly installed, the
passenger front airbag will not deploy.
The 7 indicator lamp located on the center console
will be illuminated, except with electronic key removed
or in starter switch position 0. The system does not
deactivate the door mounted side impact airbag.

After turning electronic key in starter switch to
position 1 or 2, the 7 indicator lamp located on the
center console comes on for approx. 6 seconds and then
extinguishes.
If the indicator lamp should not come on or is
continuously lit, the system is not functioning. You must
see an authorized Mercedes-Benz Center before seating
any child on the front passenger seat. See page 296 for
notes on the 7 indicator lamp.

Wa r n i n g !
The BabySmart
TM airbag deactivation system will
ONLY work with a special child seat designed to
operate with it. It will not work with child seats
which are not BabySmart
TM compatible.
Never place anything between seat cushion and
child seat (e.g. pillow), since it reduces the
effectiveness of the deactivation system.Follow the manufacturer’s instructions for
installation of special child seats.The passenger front airbag will not deploy only if
the 7 indicator lamp remains illuminated.Please be sure to check the indicator every time
you use the special system child seat. Should the
light go out while the restraint is installed, please
check installation. If the light remains out, do not
use the BabySmart
TM restraint to transport children
on the front passenger seat until the system has
been repaired.

Supplemental restraint system (SRS)
Airbags are intended as a supplement to seat belts.
Airbags alone cannot protect as well as airbags plus
seat belts in impacts for which the airbags were
designed to operate, and do not afford any protection
whatsoever in crashes for which the airbags are not
designed to deploy.
The SRS uses two crash severity levels (thresholds) to
activate either the emergency tensioning retractor (ETR)
or front airbag or both. Activation depends on the
direction and severity of the impact exceeding the
preset thresholds and whether the seat belt is fastened.Seat belt fastened
•first threshold exceeded: ETR activates
•second threshold exceeded: airbag also activates
Seat belt not fastened
Front seats:
•first threshold exceeded: airbag activates, not ETR
Rear seats:
•first threshold exceeded: ETR activates
Driver and front passenger and rear seat systems
operate independently of each other.

The seat belts for the front and rear seats are equipped
with emergency tensioning retractors. These tensioning
retractors are located in each belt’s inertia reel and
become operationally ready with the electronic key in
starter switch position 1 or 2.
The emergency tensioning retractors are designed to
activate only when the seat belts are fastened during
frontal impacts exceeding the first threshold of the SRS and in rear impacts exceeding a preset severity level.
They remove slack from the belts in such a way that the
seat belts fit more snugly against the body restricting its
forward movement as much as possible.
In cases of other frontal impacts, angled impacts, roll-
overs, certain side impacts, or other accidents without
sufficient frontal or rear impact forces, the emergency
tensioning retractors will not be activated. The driver
and passengers will then be protected by the fastened
seat belts and inertia reel in the usual manner.
