cluster displayPractical hints Car care Index Automatic central locking
The central locking switch also operates the automatic
central locking.
With the automatic central locking system activated and
the engine running, the doors and trunk are locked at
vehicle speeds of approximately 9 mph (15 km / h) or
more.
To a c ti va te :
With key in steering lock position 2 hold upper portion
of switch (1) for a minimum of 5 seconds.
To deactivate:
With key in steering lock position 2 hold lower portion
of switch (2) for a minimum of 5 seconds.
Notes:
If doors are unlocked with the central locking switch
after activating the automatic central locking, and
neither door is opened, then the doors remain unlocked
even at vehicle speeds of approximately 9 mph
(15 km / h) or more.If a door is opened from the inside at speeds of
approximately 9 mph (15 km / h) or less with the
automatic central locking activated, the door will again
be automatically locked at speeds of approximately
9 mph (15 km / h) or more.
Important!
When towing the vehicle, or with the vehicle on a
dynamometer test stand, please, note the following:
With the engine running, the vehicle doors will lock if
the left front wheel spins at vehicle speeds of
approximately 9 mph (15 km / h) or more.
To prevent vehicle door locks from locking, deactivate
the automatic central locking.
Emergency unlocking in case of accident
The doors unlock automatically a short time after an
accident in which an airbag or emergency tensioning
retractor deploys (this is intended to aid rescue and
exit). However, the key must still be in the steering lock
position 1 or 2.
Additionally the hazard warning flashers turn on
automatically and the interior lights switch on for
approximately 30 minutes.

Prior to operating the vehicle, the driver should adjust
the seat height for proper vision as well as fore / aft
placement and backrest angle to insure adequate
control, reach, operation, and comfort. The head
restraint should also be adjusted for proper height. See
also airbag section on page 58 for proper seat
positioning.
In addition, also adjust the steering wheel to ensure
adequate control, reach, operation, and comfort.
Both the inside and outside rear view mirrors should be
adjusted for adequate rearward vision.
Fasten seat belts. Infants and small children should be
seated in a properly secured restraint system that
complies with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
All seat, head restraint, steering wheel, and rear view
mirror adjustments as well as fastening of seat belts
should be done before the vehicle is put into motion.
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 can 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 the 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.

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.

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
Push the release button (3) in the belt buckle (2).
Allow the retractor to completely rewind the seat belt by
guiding the latch plate (1).
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.

USE CHILD RESTRAINTS PROPERLY.

USE CHILD RESTRAINTS PROPERLY.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.Children too big for child restraint systems must
ride in back seats using regular seat belts. Position
shoulder belt across chest and shoulder, not face or
neck. A booster seat may be necessary to achieve
proper belt positioning.

TM airbag deactivation system
Special BabySmart
TM compatible child seats, designed
for use with the Mercedes-Benz system and available at
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 in the instrument cluster will be
illuminated, except with key removed or in steering lock
position 0. The system does not deactivate the door
mounted side impact airbag.
Self-test BabySmart

withoutspecialchildseatinstalled
After turning key in steering lock to position 1 or 2, the
7 indicator lamp located in the instrument cluster
comes on for approximately 6 seconds, extinguishes,
then blinks once.
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.
BabySmart
TM is a trademark of Siemens Automotive Corp.
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. The
bottom of the child seat must make full contact
with the passenger seat cushion. An incorrectly
mounted child seat could cause injuries to the
child in case of an accident instead of protecting
the child.
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.
