Special BabySmart
TM compatible child
seats, designed for use with the
Mercedes-Benz system and available at
any authorized Mercedes-Benz Center, are
required for use with the BabySmart
TM air-
bag deactivation system. With the special
seat properly installed, the passenger front
airbag will not deploy.
The
7
indicator lamp located in the in-
strument cluster will be illuminated, ex-
cept with the key removed or in the
steering lock position0.
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.
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.
Warning!
G
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, re-
m o v e i t f r o m t h e v e h i c l e o r s e c u r e i t w i t h t h e
seat belt to prevent the child restraint from
becoming a projectile in the event of an ac-
cident.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and may cause an accident
and/or serious personal injury.
iThe system does not deactivate the
door mounted side impact airbag, the
window curtain airbags and the emer-
gency tensioning device.

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.

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.

68 Safety and SecurityOccupant safety
When using the center second row seat
for a top tether strap, the left third row
seat should only be used for a child re-
straint system, since exiting the vehicle
may not be possible in an emergency
due to the routing of the top tether
strap.
When installing an infant or child re-
straint system with a top tether strap
on the left second row seat, the left
third row seat should not be occupied. Child seat anchors – “LATCH” type
This vehicle is provided with two “LATCH”
(LOWER Anchors and Tethers for CHil-
dren) type anchors (at each of the outer
rear seats and in the optional third row
seats) for installation of a “LATCH” seat
with matching mounting fittings.
1Anchors
Install a “LATCH” type child seat ac-
cording to the manufacturer’s instruc-
tions.
!An infant and child restraint system
must not be installed on the right
second row seat while a passenger
rides in a third row seat. An infant and
child restraint system installed on the
right second row seat will prevent the
use of the easy-entry/exit feature
(page 95).
iWith a child seat installed in the left
rear seat, the seat belt for the center
seat occupied by a passenger must op-
erate freely. Guide seat belt between
its seat cushion mount and backrest
mount along outside of right side child
seat mount.
Non-“LATCH” type child seats may also
be used and can be installed using the
vehicle’s seat belt system. Install child
seat according to the manufacturer’s
instructions.

71 Safety and Security
Driving and safety systems
Driving and safety systems
In this section you will find information on
the following driving safety systems:
ABS (Antilock Brake System)
BAS (Brake Assist System)
4-ETS (Electronic Traction System)
EBP (Electronic Brake Proportioning)
ESP (Electronic Stability Program)
ABS
The ABS regulates the brake pressure so
that the wheels do not lock during braking.
This allows you to maintain the ability to
steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure.
The
-
warning lamp in the instrument
cluster (page 25) lights up when you
turn the key to position2. It goes out when
the engine is running.
iIn winter operation, the maximum ef-
fectiveness of the ABS, ESP, EBP and
4-ETS is only achieved with winter tires
(M + S tires), or snow chains as re-
quired.
Warning!
G
The following factors increase the risk of ac-
cidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
ABS, BAS, ESP and 4-ETS cannot reduce this
risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
ABS and significantly reduces braking effec-
tiveness.
Page 72 of 321

72 Safety and SecurityDriving and safety systemsBraking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.LOW RANGE– ABS
During off-road driving a special low range
system for the antilock brake system (ABS)
is operational with transmission in LOW
RANGE mode (
page 118).
When applying the service brakes at
speeds below approximately
18 mph (30 km / h), the front wheels are
locked cyclically to shorten the braking
distance (dig in effect). This affects steer-
ing the vehicle.
More information can be found in the
“Practical hints” section (
page 225).
iWith the ABS malfunctioning, the BAS,
EBP ESP and 4-ETS are also switched
off.
Normal driving and braking functions
are still available.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction af-
forded. The ABS cannot prevent accidents,
including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ABS equipped
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize the user’s safety or the safety of
others.
