66 Safety and SecurityOccupant safetySelf-test BabySmart
TM
without special
child seat installed
After turning key in steering lock to
position 1 or 2, the
7
indicator lamp lo-
cated 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 func-
tioning. You must see an authorized
Mercedes-Benz Light Truck Center before
seating any child on the front passenger
seat.
More information can be found in the
“Practical hints” section (page 232).
BabySmart
TM is a trademark of Siemens
Automotive Corp.
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.
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
front passenger airbag will not deploy only if
the
7
indicator lamp remains illuminat-
ed.
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.
Warning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
passenger seat. Signals from such devices
may interfere with the BabySmart
TM system.
Such signal interference may cause the
7
indicator lamp not to come on during
self-test or be continuously lit, indicating
that the system is not functioning.

An incorrectly mounted child seat may come
loose during an accident.
Damaged or impact damaged child seats or
child seat mounting fittings must be re-
placed.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system.
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.
Warning!

Activate the override switch in the rear when
children are riding in the car. The children
could otherwise injure themselves, e.g. by
becoming trapped in the window opening.
When leaving the vehicle, always remove the
key from the steering lock, and lock the ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious
personal injury.

ways set the parking brake in addi-
tion to placing the selector lever in
positionP to secure the vehicle.
The key can only be removed from
the steering lock with the selector le-
ver in positionP. With the key re-
moved the selector lever is locked in

No power is transmitted from the en-
gine to the drive axle. When the
brakes are released, the vehicle can
be moved freely (pushed or towed).
To avoid damage to the transmission,
never engageN while driving.
If the ESP is deactivated or malfunc-
tioning:
Only move selector lever toN if the
vehicle is in danger of skidding (e.g.
on icy roads).
D
The transmission shifts automatical-
ly. All five forward gears are avail-
able.
!Coasting the vehicle, or driving for any
other reason with selector lever inN
can result in transmission damage that
is not covered by the Mercedes-Benz
Limited Warranty.Warning!
G
Getting out of your vehicle with the selector
lever not fully engaged in positionP is dan-
gerous. Also, positionP alone is not intend-
ed to or capable of preventing your vehicle
from moving, possibly hitting people or ob-
jects.
Always set the parking brake in addition to
shifting to positionP (
page 50).
When parked on an incline, turn the front
wheels towards the road curb.
Warning!
G
When leaving the vehicle always remove the
key from the steering lock and lock the vehi-
cle. Do not leave children unattended in the
vehicle, or with access to an unlocked vehi-
cle. Children could move the selector lever
from positionP, which could result in an ac-
cident and/or serious personal injury.
