notice to the subsequent owner that it is equipped with
an “SRS” by alerting them to the applicable section in
the Operator’s Manual.Infant and child restraint systems
We recommend all infants and children be properly
restrained at all times while the vehicle is in motion. All
lap-shoulder belts except the driver seat belt have
special seat belt retractors for secure fastening of child
restraints.
To activate, 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.
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 75 (installation of infant and
child restraint systems).
• For your protection and the protection of
others, when scrapping the airbag unit or
emergency tensioning retractor, our safety
instructions must be followed. These
instructions are available from your
authorized Mercedes-Benz Center.• Given the considerable deployment speed and
the textile structure of the airbags, there is the
possibility of abrasions or other injuries
resulting from airbag deployment.
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.

Important!
The use of infant or child restraints is req uired 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 the
inside of the vehicle and to infant or child restraints.
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
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 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.

This vehicle is provided with tether anchorages for a top
tether strap at each of the rear seating positions.
Prior to installing a tether strap, remove cover (1) from
anchorage ring (2) and store in a convenient place (e.g.
glove box).
Infants and small children should never share a
seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.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 for children from 41 lbs. to
the point where a lap / shoulder belt fits properly
without one.When the child restraint is not in use, remove it
from the vehicle or secure it with the seat belt to
prevent the child restraint from becoming a
projectile in the event of an accident.

the anchorage ring (2). For safety, please make sure that
the hook has attached to the ring beyond the safety
catch, as illustrated.
After removing the tether strap, reinstall the cover (1).Child seat mounts
This vehicle is provided with two mounts (at each of the
outer rear seats) for the installation of a child seat
having the matching mounting fittings. The mounts can
be folded back between the seat cushion and the
backrest.
To install a child seat, the mounts (1) must be folded
forward until they lock in place. To do so, grip inner side
of mounts and fold forward. Install child seat according
to the manufacturer’s instructions.

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.

The operational readiness of the airbag
system is verified by the indicator lamp
“SRS” in the instrument cluster when
turning the electronic key in starter switch to position 1
or 2. If no fault is detected, the lamp will go out after
approximately 4 seconds; after the lamp goes out, the
system continues to monitor the components and
circuitry of the airbag system and will indicate a
malfunction by coming on again.
See page 65 for notes on airbags, see page 63 for belt
tensioners and page 55 for infant and child seat
restraint.Fuel reserve warning
1Fuel reserve indicator
When the warning lamp (1) comes on after starting the
engine, or if comes on while driving, it indicates that
the fuel level is down to the reserve quantity of
approximately 2.1 US gal (8 liters).
See page 264 for notes on refueling the vehicle.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have the
system checked; otherwise the “SRS” may not be
activated when needed in an accident, which could
result in serious or fatal injury, or it might deploy
unexpectedly and unnecessarily which could also
result in injury.
