2Ignition (power supply for all electrical
consumers) and driving position
All lamps (except high beam headlamp
indicator lamp and turn signal indicator
lamps unless activated) in the instru-
ment cluster come on. If a lamp in the
instrument cluster fails to come on
when the ignition is switched on, have
it checked and replaced if necessary. If
a lamp in the instrument cluster
remains on after starting the engine or
comes on while driving, refer to “Lamps
in instrument cluster” (
page 324).
3Starting position
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended 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.

Adjusting
Adjusting
Seats
Warning!G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.
Warning!G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back 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 seat belt would apply force at
the abdomen or neck. That could cause
serious or fatal injuries.
The seat backrest and seat belts provide the
best restraint when the wearer is in a nearly
upright position and seat belts are properly
positioned on the body. Your seat must be
adjusted so that you can correctly fasten
your seat belt (
page 48).
Observe the following points:
Adjust the backrest until your arms are
slightly angled when holding the
steering wheel.
Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to operate the
controls properly.
Adjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports
the back of the head at eye level.
Never place hands under the seat or
near any moving parts while a seat is
being adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the power seats can be
operated when the respective door is open.
Therefore, do not leave children unattended
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.

For more information, see “Seats”
(
page 108).
Warning!G
Do not drive the vehicle without the seat
head restraints. Head restraints are
intended to help reduce injuries during an
accident.
For your protection, drive only with properly
positioned and engaged head restraints.
Adjust the head restraint in such a way that
it is as close to the head as possible and the
center of the head restraint supports the
back of the head at eye level. This will
reduce the potential for injury to the head
and neck in the event of an accident or
similar situation.

ment feature can be operated when the
driver’s door is open. Therefore, do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child’s

53 Getting started
Driving
Proper use of seat belts
Do not twist the seat belt when fasten-
ing.
Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the seat belt under
your arm. For this purpose, you can
adjust the height of the seat belt guide
(
page 52).
Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.
Place the seat backrest on adjustable
seat backrests in a nearly upright
position.
Never use a seat belt for more than one
person at a time.
Do not fasten a seat belt around a
person and another object at the same
time. When using a seat belt to secure
infant restraints, toddler restraints or
children in booster seats, always follow
the child seat manufacturer’s instruc-
tions.
Check your seat belt periodically
during travel to make sure that it is
properly positioned.
Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
Warning!G
Do not pass seat belts over sharp edges.
They could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment mecha-
nism. This could damage the seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the seat belts.
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.
Damaged seat belts or seat belts that were
highly stressed in an accident must be
replaced. Contact an authorized
Mercedes-Benz Light Truck Center.
