Special BabySmart
TM compatible child
seats, designed for use with the
Mercedes-Benz system, are required for
use with the BabySmart
TM air bag deactiva-
tion system. Please contact an authorized
Mercedes-Benz Light Truck Center for in-
formation on availability. With the special
child seat properly installed, the front pas-
senger front air bag will not deploy.The 59indicator lamp locat-
ed in the center console will be illuminat-
ed, except with the SmartKey removed or
the starter switch in position0.
Self-test BabySmart
TM without special
child seat installed
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice, the 59indicator lamp
located in the center console comes on for
approximately 6 seconds and then goes
out.
If the 59indicator lamp
should not come on or is continuously lit,
the system is not functioning. You must
see an authorized Mercedes-Benz Light
Truck Center before seating any child on
the passenger seat.
More information can be found in the
“Practical hints” section (
page 450).
iThe system does not deactivate the side im-
pact air bag, the window curtain air bag and the
emergency tensioning device.
Warning!G
The BabySmartTM air bag 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
USE SEAT BELTS PROPERLY

Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.

Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver air bag, pas-
senger front air bag, side impact air
bags, window curtain air bags for side
windows), ETD (seat belt emergency
tensioning device), and front seat knee
bolsters. The system is designed to en-
hance the protection offered to properly
belted occupants in certain frontal (front
air bags and ETD) and side (side impact,
window curtain air bags and ETD) im-
pacts which exceed preset deployment
thresholds and in certain rollovers (win-
dow curtain air bags and ETD).

Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would in-
crease the chance of head and neck in-
juries. The belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal or-
gans such as your liver or spleen.

Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, SmartKeys, etc., as
these might cause injuries.

Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the belt is positioned across your
abdomen, it could cause serious injuries
in a crash.

Never use a seat belt for more than one
person at time. Do not fasten a seat belt
around a person and another person or
other objects.

Belts should not be worn twisted. In a
crash, you would not have the full width
of the belt to distribute impact forces.
The twisted belt against your body could
cause injuries.

Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.

Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.

When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.

100 Safety and Security
Occupant safety
Securely fasten hook3, which is part
of the tether strap4, to anchorage
ring2.
Make sure

the top tether strap is not twisted

the head restraint is installed and
positioned such that the top tether
strap can pass freely between the
head restraint and top of seat back-
rest

top tether strap is positioned be-
tween the seat backrest and the
cargo compartment cover blind (if
installed)

the top tether strap is positioned
between the seat backrest and the
cargo net* (if installed)
Lower the head restraint if necessary
(
page 137).
Make sure the top tether strap can
pass freely between the head restraint
and top of seat backrest.
Install the child restraint system and
tighten the top tether strap according
to the child restraint manufacturer’s in-
structions.
Blocking of rear door window operation
With the override switch you can disable
the rear side window switches in the rear
door panels.
Warning!G
After installing top tether straps, make sure
that the seat backrests are in an upright po-
sition and are properly locked. Check for
secure locking by pushing and pulling on the
seat backrests. If a seat backrest is not
properly locked, the seat backrest could
fold. The child seat would no longer be prop-
erly supported or positioned to provide its
intended benefit.
Warning!G
Activate the override switch when children
are riding in the back seats of the vehicle.
The children could otherwise injure them-
selves, e.g. by becoming trapped in the win-
dow opening.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an
accident and/or serious personal injury.

Warning!G
Never switch off the ESP® when you see the
ESP® warning lampv flashing in the in-
strument cluster. In this case, proceed as
follows:

While driving off, apply as little throttle
as possible.

While driving, ease up on the accelera-
tor.

Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP
® cannot prevent accidents result-
ing from excessive speed.
Warning!G
The ESP® cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
®
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of an ESP
® equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
!Operational or performance test must only
be conducted on a two-axle dynamometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!Because the ESP® operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO* start/stop button in
position0or1) when testing the parking brake
on a brake test dynamometer and such testing
should be no longer than 10 seconds.
Active braking action through the ESP
® may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
iThe ESP® will only function properly if you
use wheels of the recommended tire size
(
page 554).

switched off temporarily to prevent overheating
of the drive wheel brakes. In addition, the
message
