Caution!
Do not remove head restraints except when mounting
seat covers. For removal see page 43. Whenever head
restraints have been removed be sure to reinstall them
before driving.
Wa r n i n g !
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause the
driver to lose control of the vehicle.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.Never place hands under seat or near any moving
parts while a seat is being adjusted.
Wa r n i n g !
When leaving the vehicle always remove the key
from the steering lock, and lock your vehicle.Do not leave children unattended in the vehicle or
with access to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause serious
personal injury.

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
TM
without special child seat installed
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.Follow the manufacturer’s instructions for
installation of special child seats.
The passenger side 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.

cluster displayPractical hints Car care Index Infant and child restraint systems
We recommend t ha t all infa nts and children be properly
restrained at all times while the vehicle is in motion. All
lap-shoulder belts except the driver’s seat belt have
special seat belt retractors for secure fastening of child
restraints.
To fasten a child restraint follow child restraint
instructions for routing. Then pull shoulder belt out
completely and let it retract. During the seat belt
retraction a ratcheting sound can be heard to indicate
that the special seat belt retractor is activated. The belt
is now locked. Push down on child restraint to take up
any slack.
To deactivate, release seat belt buckle and let seat belt
retract completely. The seat belt can again be used in
the usual manner.
Note:
For child seats with mounting fittings for tether
anchorages refer to page 67 (installation of infant and
child restra int systems).Important!
The use of infant or child restraints is required by law in
all 50 states and all Canadian provinces.
Infants and small children should be seated in an
appropriate infant or child restraint system properly
secured by a lap-shoulder belt, and that complies with
U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213.
A statement by the child restraint manufacturer of
compliance with this standard can be found on the
instruction label on the restraint and in the instruction
manual provided with the restraint.
When using any infant or child restraint system, be sure
to carefully read and follow all manufacturer’s
instructions for installation and use.
Please read and observe warning labels affixed to inside
of vehicle and to infant or child restraints.
Wa r n i n g !
Never release the seat belt buckle while vehicle is
in motion, since the special seat belt retractor will
be deactivated.
