mation given here.
If you are already familiar with the basic
functions described here, the “Controls in
detail” section will help you with further in-
formation. The corresponding page refer-
ences are at the end of each segment.

Driving
Starting difficulties
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
key: Turn key in starter to position0
and repeat starting procedure.
If you are starting the engine with
KEYLESS-GO: Close any doors that
may be open to allow for better detec-
tion of the card.
Or:
Start the engine with the key as radio
signals from another source may be in-
terfering with the KEYLESS-GO card.
Repeat the starting procedure
(page 39). Remember that extended
starting attempts can drain the battery.
Get a jump start (
page 323).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
Notify an authorized Mercedes-Benz
Center.

The indicator lamp
;
(USA only) or

LESS-GO card (if so equipped) with you and

65 Safety and Security
Occupant safety
The
7
indicator lamp located on the
glove box will be illuminated, except with
the key removed or in the starter switch
position0.
Self-test BabySmart
TM
without special
child seat installed
After turning the key in the starter switch
to position1 or2, the 7
indicator lamp
located on the glove box lights up for ap-
prox. 6 seconds and then goes out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized
Mercedes-Benz Center before seating any
child on the passenger seat.
iThe system does not deactivate the
head-thorax airbag and the emergency
tensioning device.
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem 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 sys-
tem. 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.
Warning!
G
When using a BabySmart compatible child
seat on the front passenger seat, the front
passenger 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 passenger seat until the system has
been repaired.
