cluster displayPractical hints Car care Index Supplemental restraint system (SRS) indicator lamp
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 91 for notes on airbags, see page 89 for belt
tensioners and page 81 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 it comes on while driving, it indicates that
the fuel level is down to the reserve quantity of
approximately 2.9 gal (11 liters).
See page 296 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.

position 2, the seat belt nonusage warning

AIRBAG OFF indicator lamp
The 7 indicator lamp will light up for approximately
6 seconds when you turn the electronic key in starter
switch to position 1 or 2.
It does not light up if there is a fault in the system.
The 7 indicator lamp stays lit as long as a
BabySmart
TM child seat is properly installed on the front
passenger seat. It indicates that the front passenger
airbag is switched off.
See page 88 for BabySmart
TM airbag and its deactivation
system.
Baby Smart
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 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.
