Tire and loading terminology
Accessory weight
The combined weight (in excess of those
standard items which may be replaced) of
automatic transmission, power steering,
power brakes, power windows, power
seats, radio, and heater, to the extent that
these items are available as
factory-installed equipment (whether
installed or not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or
bars.
Aspect ratio
Dimensional relationship between tire
section height and section width
expressed in percentage.
Warning!
G
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause
excessive heat build-up and possible tire
failure.
iFor illustration purposes only. Actual
data on tires are specific to each vehi-
cle and may vary from data shown in
above illustration.

Vehicles with Advanced TPMS*:
The tire inflation pressure is being checked.

Drive the vehicle for a few minutes.
Tire pressure monitor

a nearby radio interference source


excessive wheel sensor temperatures

As soon as the causes for the malfunction are no
longer present, the TPMS or Advanced TPMS* auto-
matically becomes active again after a few minutes
of driving.
Tire pressure monitor
Wheel sensor missing
One or more sensors malfunction (e.g. bat-
tery in one or more wheel sensor is empty).
One or more wheels without wheel sensors
mounted (e.g. spare tire).

Have the TPMS or Advanced TPMS* checked by an
authorized Mercedes-Benz Light Truck Center.

Instrument cluster
The displays and indicator/warning
lamps in the driver’s field of vision, in-
cluding the tachometer, speedometer,
engine temperature and fuel gauge.Kickdown
Depressing the accelerator past the
point of resistance shifts the transmis-
sion down to the lowest possible gear.
This very quickly accelerates the vehi-
cle and should not be used for normal
acceleration needs.
Kilopascal (kPa)
(
page 386)
Line of fall
The direct line that an object moves
downhill when influenced by the force
of gravity alone.
Locking knob
Knob on the door which indicates
whether the door is locked or un-
locked. Pushing the locking knob down
on an individual door from inside will
lock that door.Maintenance System (U.S. vehicles)
Maintenance service indicator in the
multifunction display that informs the
driver when the next vehicle mainte-
nance service is due. The Maintenance

nance service work required, and calls
for the next service accordingly.
