Manufacturer’s identification mark
Manufacturer’s identification mark2
(

page 200) denotes the tire manufacturer.
New tires have a mark with two symbols.
Retreaded tires have a mark with four
symbols. For more information on retreaded
tires (

Tire size
Code3 (
page 200) indicates the tire size.
Tire type code
Code4 (
page 200) may, at the option of
the manufacturer, be used as a descriptive
code for identifying significant characteris

tics of the tire.
Date of manufacture
Date of manufacture5 (

page 200)
identifies the week and year of manufacture.The first two figures identify the week, start

ing with "01" to represent the first full week of
the calendar year. The second two figures
represent the year.
For example, "3202" represents the 32nd
week of 2002.

Warning!
Do not overload the tires by exceeding
the specified load limit as indicated on
the Tire and Loading Information placard
located on the driver’s door B
pillar.
Overloading the tires can overheat them,
possibly causing a blowout. Overloading
the tires can also result in handling or
steering problems, or brake failure.

Tire and loading terminologyAccessory weight
The combined weight (in excess of those stan

dard items which may be replaced) of auto

matic 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 per

centage.Bar
Another metric unit for air pressure. There
are 14.5038 pounds per square inch (psi)
to 1 bar; there are 100 kilopascals (kPa)
to 1 bar.
Bead
The tire bead contains steel wires wrapped by
steel cords that hold the tire onto the rim.
Cold tire inflation pressure
Tire inflation pressure when your vehicle has
been sitting for at least 3 hours or driven no
more than 1 mile (1.6 km).
Curb weight
The weight of a motor vehicle with standard
equipment including the maximum capacity of
fuel, oil, and coolant, and, if so equipped, air
conditioning and additional optional equip

ment, but without passengers and cargo.

weight. The gross vehicle weight on each axle
must never exceed the GAWR for the front and
rear axle indicated on the certification label
located on the driver’s door B

fuel, and cargo. It is indicated on certification
label located on the driver’s door B
pillar.
Kilopascal (kPa)
The metric unit for air pressure. There are
6.9 kPa to 1 psi; another metric unit for air
pressure is bars. There are 100 kilopascals
(kPa) to 1 bar.
Maximum 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 permissible tire inflation pressure
This number is the greatest amount of air
pressure that should ever be put in the tire.
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 regu

lar production options weighing over 5 lbs
(2.3 kilograms) in excess of those standard
items which they replace, not previously con

sidered in curb weight or accessory weight,
including heavy duty brakes, ride levelers,
roof rack, heavy duty battery, and special
trim.

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 tiresThoroughly clean the mounting face of the
wheels and brake disks, i.e. the inner side of
the wheels/tires each time the wheels/tires
are changed. Check for and ensure proper
tire inflation pressure.For information on wheel change, see "Flat
tire" (

page 265).
G
Warning!
Do not rotate front and rear wheels as
they have different dimensions, e.g. rim
size, wheel offset etc. Otherwise, the
handling can be affected and you could
endanger yourself and others.
G
Warning!
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
81 lb
ft (110 Nm).
Only use genuine smart wheel bolts
specified for your vehicle’s rims.

illuminates and remains illuminated with
the weight of a typical adult or someone
larger than a small individual on the pas

senger seat, do not have any passenger
use the passenger seat until the system
has been repaired.G
Warning!
If the57indicator lamp
does not illuminate or remains out with
the weight of a typical 12

Warning!
No racks or loads may be secured to the
roof of the vehicle, as:
• the panorama roof* may be damaged,
thus injuring persons.
• this can have a substantial adverse
effect on the driving dynamics of the
vehicle, thus causing accidents.
• the rack and/or the load could detach
and through this cause an accident or
other people could be injured by the
