Occupant safety
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Airbags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.
Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Never use a seat belt for more than one per-
son at a time.
Warning!
G
Damaged seat belts or belts that were highly
stressed in an accident must be replaced
and their anchoring points must also be
checked.
Only use seat belts which have been ap-
proved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
or to failure.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Light Truck Center.

Occupant safety
Emergency tensioning device, seat belt
force limiter
The seat belts for the front seats are
equipped with emergency tensioning de-
vices and belt force limiters. The outboard
passenger seats belts (except in the third
row seats*) are equipped with emergency
tensioning devices.
The ETD is designed to activate in the
following cases:

in frontal or rear-end impacts exceed-
ing a preset severity level


if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 58)In an impact, emergency tensioning devic-
es remove slack from the belts in such a
way that the seat belts fit more snugly
against the body. Belt force limiters reduce
the force exerted by the seat belts on oc-
cupants during a crash.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:

Secure the child using an infant or child
restraint appropriate to the age and
size of the child.


Make sure the infant or child is proper-
ly secured by a belt at all times while
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
authorized Mercedes-Benz Light Truck
Center.
iThe ETDs for the front seats will only
activate if the respective front seat belt
is fastened (latch plate properly insert-
ed into buckle).
The ETDs for the rear outer seats will
activate with or without the respective
seat belt fastened.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Light Truck Center.!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact airbag on the front passenger
side to deploy in a crash which exceeds
the system’s deployment threshold.

Special BabySmart

compatible child
seats, designed for use with the
Mercedes-Benz system and available at
any authorized Mercedes-Benz Light Truck
Center, are required for use with the
BabySmart

With the special seat properly installed,
the passenger front airbag will not deploy.
The 7indicator lamp located in the in-
strument cluster will be illuminated, ex-

After turning the key in the steering lock to
position1 or2, the 7indicator lamp lo-
cated in the instrument cluster comes on
for approximately six seconds, extin-
guishes, then flashes 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.
For more information, see the “Practical
hints” section (
page 249).
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 until
they reach a height where a lap / shoulder
belt fits properly without a booster.
When the child restraint is not in use, re-
move it from the vehicle or secure it with the
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.

Installation of infant and child restraint

Guide top tether strap between head
restraint and top of seat back. Head
restraint must be installed and posi-
tioned such that the top tether strap
can pass freely between the head re-
straint and top of seat back.

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
passenger front airbag will not deploy only if
the 7indicator lamp remains illumi-
nated.
Please make sure to check the indicator ev-
ery 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
front passenger seat. Signals from such de-
vices may interfere with the BabySmart
TM
system. Such signal interference may cause
the 7indicator lamp not to come on dur-
ing self-test or be continuously lit, indicating
that the system is not functioning.

76 Safety and SecurityDriving safety systemsIn this section you will find information on
the following driving safety systems:

ABS
The Antilock Brake System (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 -indicator lamp in the instrument
cluster (
page 25) comes on when you
turn the key in the steering lock to
position2. It goes out when the engine is
running.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP, the EBP, and the 4-ETS is only
achieved with winter tires (M + S tires)
or snow chains as required.
Warning!
G
The following factors increase the risk of
accidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The 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
the ABS and significantly reduces braking
effectiveness.
