51 Getting started
Driving
After a cold start, the automatic transmis-
sion shifts at a higher revolution. This al-
lows the catalytic converter to reach its
operating temperature earlier.

You can open the doors from inside.
Open doors only when the conditions
are safe to do so.
You can deactivate the automatic
locking using the control system
(

!
Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

Occupant safety
Warning!G
The service life of the passenger front airbag
extends to the date indicated on the label lo-
cated on the driver side B pillar. To provide
continued reliability after that date, they
should be inspected by an authorized
Mercedes-Benz Light Truck Center at that
time and replaced when necessary.
Warning!G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear your
seat belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and make sure it is properly
positioned on your body (
page 68).
Since the airbag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the airbag.
Occupants who are unbelted, out of position
or too close to the airbag can be seriously
injured or killed by an airbag as it inflates
with great force in the blink of an eye:
Sit properly belted in a nearly upright
position with your back against the
backrest.
Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least
ten inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Light Truck Center.
Do not lean with your head or chest
close to the steering wheel or dash-
board.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front airbag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
66 Safety and Security
Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
airbag Your vehicle was originally equipped
with airbags that are designed to acti-
vate in certain impacts exceeding a
preset threshold to reduce the poten-
tial and severity of injury. It is important
to your safety and that of your passen-
ger that you replace deployed airbags
and repair any malfunctioning airbags
to make sure the vehicle will continue
to provide supplemental crash protec-
tion for occupants.
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. Use only belts in-
stalled or supplied by an authorized
Mercedes-Benz Light Truck Center.
No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, passenger front airbag cov-
er, outboard sides of the front seat
backrests, door trim panels, or door
frame trims, and installation of addition-
al electrical /electronic equipment on or
near SRS components and wiring. Keep
area between airbags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).
Airbags and emergency tensioning de-
vices (ETDs) are designed to function on
a one-time-only basis. An airbag or ETD
that was activated must be replaced.
Do not pass belts over sharp edges.
They could tear.
Do not make any modification that could
change the effectiveness of the belts.
Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.
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.
Airbag system components will be hot
after an airbag has inflated. Do not
touch.
71 Safety and Security
Occupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.
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 62)In an impact, emergency tensioning
devices remove slack from the belts in
such a way that the seat belts fit more
snugly against the body.
Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to manage impact forces. The
twisted belt against your body could
cause injuries.
Pregnant women should also 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.
i
The ETDs for the front seats will only
activate if the respective front seat belt
is fastened (latch plate properly
inserted 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 passenger
front airbag and, with the seat belt
fastened to secure the object, the ETD
on the front passenger side to deploy in
a crash which exceeds the system’s
deployment threshold.

160 Controls in detail
Differential locks
A few words about differentials and
differential locks
When a vehicle negotiates a turn, wheels
on the outside of the curve must travel far-
ther and rotate faster than the inside
wheels. The differential, the operation of a
set of gears that allows the powered
wheels in a vehicle to turn at different
speeds, makes this essential function pos-
sible.
The drawback is that the differential also
sends most of the engine’s power to the
wheel with the least load or strain on it. For
example, if one of a vehicle’s powered
wheels sits on a patch of snow and spins
because there is no traction, all of the en-
gine’s power will go to that wheel because
the power will take the path of least resis-
tance. Meanwhile, the opposite wheel, sit-
ting on dry pavement where it could get
enough grip to start the vehicle moving,
sits idle because it receives no power.The Electronic Traction System (ETS) ad-
dresses this problem and provides for
good control and steering ability by auto-
matically slowing the slipping wheel and
thus increasing the power to the other
non-slipping drive wheels to get the vehicle
moving. The ESP and ETS in this vehicle
feature such intelligent limited-slip differ-
ential technology, ideally suited for
on-road and light off-road driving. Transfer
case position LOW (
page 157) also en-
hances off-road driving capabilities
(
page 227).
More extreme off-road conditions may call
for another solution, engaging a differen-
tial lock or preventing the differential from
operating altogether. As part of its stan-
dard equipment, this vehicle comes with
three differential locks: front, transfer case
(center) and rear. Each can be engaged
simply by pushing dashboard-mounted
buttons in sequential order (center, rear,
front) (
page 161). When the transfer
case (center) differential is locked, half of
the engine’s power is automatically distrib-
uted to the front wheels and half to the rear wheels. When the rear differential is
locked, power going to the rear wheels is
equally distributed, so that both rear
wheels turn at the same speed and torque.
When the front differential is locked, all
four wheels now turn with equal power and
torque. Please be aware that engaging the
differential locks will significantly reduce
the steering ability of the vehicle.
For your safety and the safety of others
and to prevent damage to the vehicle, the
differential locks must not be engaged
when driving on paved roads. It is impor-
tant to understand that during
on-road/paved driving, differentials are
absolutely necessary for providing the es-
sential control and steering ability of the
vehicle. The differential locks, therefore,
must not be engaged when driving on
paved roads and should only be used to
the extent necessary to negotiate off-road
conditions which cannot be handled by the
systems (automatic 4-ETS, the ESP, manu-
al switch position “LOW” of transfer case)
this vehicle comes equipped with.
