93 Safety and Security
Occupant safety
You cannot remove the active head
restraint on the driver’s and front
passenger’s seats.
For removal of the active head restraints
we recommend that you contact an
authorized Mercedes-Benz Light Truck
Center.
For information on head restraint adjust-
ment, see “Seats” (
page 45).
For information on resetting the activated
active head restraints, see “Resetting acti-
vated head restraints” (
page 504).
Rear head restraintsChildren 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
properly secured at all times while the
vehicle is in motion.
Warning!G
Do not drive the vehicle without the seat
head restraints installed when the rear seats
are occupied. Head restraints are intended
to help reduce injuries during an accident.
With a rear seat occupied, make sure to
move the respective head restraint up from
the lowest non-use position and have the
occupant adjust the head restraint properly.
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that
it is as close to the head as possible and 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.
Warning!G
Do not leave children unattended in the
vehicle, even if they are secured in a child re-
straint system. The children could

injure themselves on parts of the vehicle

be seriously or fatally injured through
excessive exposure to extreme heat or
cold

Resetting trip odometer
Make sure you are viewing the trip odome-
ter display (
page 157).
If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel (
page 158) repeatedly until
the trip odometer appears in the multi-
function display.
Press and hold reset button2 in the
instrument cluster (
page 155) until
the trip odometer is reset.
Tachometer
The red marking on the tachometer
(
page 26) denotes excessive engine
speed.To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The outside temperature is displayed in the
multifunction display (
page 157).The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. This
means that the accuracy of the displayed
temperature can only be verified by com-
parison to a thermometer placed next to
the sensor, not by comparison to external
displays (e.g. bank signs etc.).
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.!Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Warning!G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
