396 OperationTires and wheelsMaximum load rating
The maximum load in kilograms and
pounds that can be carried by the tire.
Maximum loaded vehicle weight
The sum of curb weight, accessory weight,
total load limit, and production options
weight.
Maximum tire inflation pressure
This number is the greatest amount of air
pressure that should ever be put in the tire
under normal driving conditions.
Normal occupant weight
The number of occupants the vehicle is
designed to seat, multiplied by
68 kilograms (150 lbs).
Occupant distribution
The distribution of occupants in a vehicle
at their designated seating positions.Production options weight
The combined weight of those installed
regular production options weighing over
5 lbs (2.3 kilograms) in excess of those
standard items which they replace, not
previously considered in curb weight or
accessory weight, including heavy duty
brakes, ride levelers, roof rack, heavy duty
battery, and special trim.
PSI (P
ounds per s
quare i
nch)
A standard unit of measure for air pressure
-> bar, kilopascal (kPa).
Recommended tire inflation pressure
Recommended tire inflation pressure
listed on placard located on driver’s door
B-pillar for normal driving conditions.
Provides best handling, tread life and
riding comfort.Rim
A metal support for a tire or a tire and tube
assembly upon which the tire beads are
seated.
Sidewall
The portion of a tire between the tread and
the bead.
TIN (T
ire I
dentification N
umber)
Unique identifier which facilitates efforts
by tire manufacturers to notify purchasers
in recall situations or other safety matters
concerning tires and gives purchases the
means to easily identify such tires. The TIN
is comprised of “Manufacturer’s identifica-
tion mark”, “Tire size”, “Tire type code”
and “Date of manufacture”.
Tire load rating
Numerical code associated with the
maximum load a tire can support.

397 Operation
Tires and wheels
Tire ply composition and material used
This indicates the number of plies or the
number of layers of rubber-coated fabric in
the tire tread and sidewall. Tire manufac-
turers also must indicate the ply materials
in the tire and sidewall, which include
steel, nylon, polyester, and others.
Tire speed rating
Part of tire designation; indicates the
speed range for which a tire is approved.
Traction
Force exerted by the vehicle on the road
via the tires. The amount of grip provided.
Tread
The portion of a tire that comes into
contact with the road.Treadwear indicators
Narrow bands, sometimes called
“wear bars” that show across the tread of
a tire when only
1/16in (1.6 mm) of tread
remains.
TWR (T
ongue W
eight R
ating)
Maximum permissible weight on trailer
tongue.
Uniform Tire Quality Grading Standards
A tire information system that provides
consumers with ratings for a tire’s traction,
temperature and treadwear. Ratings are
determined by tire manufacturers using
government testing procedures. The
ratings are molded into the sidewall of the
tire.Vehicle maximum load on the tire
Load on an individual tire that is
determined by distributing to each axle its
share of the maximum loaded vehicle
weight and dividing it by two.
Rotating tires
Tire rotation can be performed on vehicles
with tires of the same dimension all
around. If your vehicle is equipped with
tires of the same dimension all around,
tires can be rotated, observing a
front-to-rear rotation pattern that will
maintain the intended rotation (spinning)
direction of the tire (
page 368).
Warning!
G
Rotate front and rear wheels only if they are
of the same dimension.
If your vehicle is equipped with mixed-size
tires (different tire dimensions front vs.
rear), tire rotation is not possible.

Make sure there is nothing between seat cushion and

Make sure no objects applying supplemental weight
onto the seat are present.
Make sure no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc.
lodged behind or around the seat, head restraints push-
ing against roof etc.). The system may recognize such
forces as supplemental weight.
If the front passenger front air bag off indicator lamp re-

not transport a child on the front passenger seat until

Front passenger airbag

See Operator’s Manual
Front passenger front air bag
is activated while driving even
though a child, small
individual, or object below
the system’s weight thresh-
old is on the front passenger
seat, or the front passenger
seat is empty. Objects on the
seat or forces acting on the
seat may make the system
sense supplemental weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Apply the parking brake (
page 65).
Switch off the ignition (
page 40).
Remove child and child restraint from front passenger seat and properly
secure the child in rear seat employing the child restraint if necessary.
Remove any other items from on and around the front passenger seat
and make sure the storage bag on the back of the front passenger seat
is empty.
Make sure that no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged behind or around the
seat, head restraints pushing against roof etc.). The system may recog-
nize such forces as supplemental weight and sense that an occupant on
the front passenger seat is of a greater weight than actually present.
Keep the seat unoccupied, close the front passenger door and switch
on the ignition (
page 40).

Front passenger airbag
disabled
See Operator’s Manual
Front passenger front air bag is
deactivated while driving even
though an adult or someone
larger than a small individual is
occupying the front passenger
seat. Forces acting on the seat
may make the system sense a
decrease in weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Apply the parking brake (
page 65).
Switch off the ignition (
page 40).
Have the front passenger vacate the seat and exit the vehicle.
Adjust the seat in a height position (
page 44).
Make sure that no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged underneath, behind
or around the seat). Such forces may cause the system to sense that
an occupant of a lesser weight than actually present is on the front
passenger seat.
Keep the seat unoccupied, close the front passenger door and switch
on the ignition (

504 Practical hintsFlat tire
Detach the electric air pump.
Store the electrical plug and the air
hose behind the flap and place the
electric air pump back in the cargo
compartment.Lowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.
Remove the jack.1-5Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of
110 lb-ft (150 Nm).
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflated tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Warning!
G
Vehicles with collapsible tire
(ML 63 AMG only):
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
pump (
page 502) before
lowering the
vehicle.
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 Nm).
