XStep 2:Determine the combined weight of
the driver and passengers that will be rid-
ing in your vehicle.
XStep 3: Subtract the combined weight of the
driver and passengers from XXX kilograms
or XXX lbs.
XStep 4: The resulting figure equals the
available amount of cargo and luggage load capacity. For example: at a sum “XXX” of
1400 lbs and five occupants each weighing
150 lbs, the amount of available cargo and
luggage load capacity is 650 lbs (1400 - 750
(5 x 150) = 650 lbs).
XStep 5: Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely exceed
the available cargo and luggage load capa-
city calculated in step 4.

Vehicle identification plate
Even if you have calculated the total cargo
carefully, you should still make sure that the
gross vehicle weight rating and the gross
axle weight rating are not exceeded. Details
can be found on the vehicle identification
plate on the B-pillar on the driver's side of
the vehicle (
Ypage 185).
Permissible gross vehicle weight: the gross
weight of the vehicle, all passengers, load
and trailer load/noseweight (if applicable)
must not exceed the permissible gross vehi-
cle weight.
Gross axle weight rating: the maximum per-
missible weight that can be carried by one
axle (front or rear axle).
To ensure that your vehicle does not exceed
the maximum permissible values (gross vehi-
cle weight and maximum gross axle weight
rating), have your loaded vehicle (including
driver, occupants, cargo, and full trailer
load if applicable) weighed on a suitable
vehicle weighbridge.

Uniform Tire Quality Grading Stand-
ards
Overview of Tire Quality Grading Stand-
ards
Uniform Tire Quality Grading Standards are
U.S. government specifications. Their pur-
pose is to provide drivers with uniform reli-
able information on tire performance data.
Tire manufacturers have to grade tires using
three performance factors: 0043tread wear
grade, 0044traction grade and 0087temperature
grade. These regulations do not apply to Can-
ada. Nevertheless, all tires sold in North
America are provided with the corresponding
quality grading markings on the sidewall of
the tire.
Quality grades can be found, where applica-
ble, on the tire sidewall between the tread
shoulder and maximum tire width.
Example:
RTreadwear grade: 200
RTraction grade:AA
RTemperature grade: A

An electronic speed limiter prevents your
vehicle from exceeding a speed of 130 mph
(210 km/h).
The speed rating of tires mounted at the fac-
tory may be higher than the maximum speed
that the electronic speed limiter permits.
Make sure that your tires have the required
speed rating, e.g. when buying new tires. The
required speed rating for your vehicle can be found in the "Tires" section (
Ypage 200).
Further information about reading tire data
can be obtained from any qualified special-
ist workshop.
Load index
In addition to the load-bearing index, load
rating 0043may also be imprinted on the side-
wall of the tire. This is located after the let-
ters that identify the speed rating
(
Ypage 191).
RIf no specification is given: no text (as in
the example above), represents a standard

RLight Load: represents a light load tire
RC, D, E: represents a load range that
depends on the maximum load that the tire
can carry at a certain pressure
iTire data is vehicle-specific and may
deviate from the data in the example.
Maximum load rating
Maximum tire load 0043is the maximum per-
missible weight for which the tire is
approved.
Do not overload the tires by exceeding the
specified load limit. The maximum permis-
sible load can be found on the vehicle's Tire
and Loading Information placard on the
B-pillar on the driver's side (
Ypage 185).
iThe actual values for tires are vehicle-
specific and may deviate from the values in

DOT, Tire Identification Number (TIN)
U.S tire regulations prescribe that every tire
manufacturer or retreader must imprint a TIN
in or on the sidewall of every tire produced.
The TIN is a unique identification number.
The TIN enables the tire manufacturers or
retreaders to inform purchasers of recalls
and other safety-relevant matters. It makes it
possible for the purchaser to easily identify
the affected tires.
The TIN is made up of manufacturer identi-
fication code 0044, tire size0087, tire type
code 0085and manufacturing date 0083.

Uniform Tire Quality Grading Standards
A uniform standard to grade the quality of
tires with regards to tread quality, tire trac-
tion and temperature characteristics. The
quality grading assessment is made by the
manufacturer following specifications from
the U.S. government. The ratings are molded
into the sidewall of the tire.
Recommended tire pressures
The recommended tire pressure applies to the
tires mounted at the factory.
The Tire and Loading Information placard
contains the recommended tire pressures for
cold tires on a fully loaded vehicle and for
the maximum permissible vehicle speed.
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and

Rim
This is the part of the wheel on which the tire
is mounted.
GAWR (Gross Axle Weight Rating)
The GAWR is the maximum gross axle weight
rating. The actual load on an axle must never
exceed the gross axle weight rating. The
gross axle weight rating can be found on the
vehicle identification plate on the B-pillar
on the driver's side.
Speed rating
The speed rating is part of the tire identi-
fication. It specifies the speed range for
which the tire is approved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight
of the vehicle including fuel, tools, the spare
wheel, accessories installed, occupants, lug-
gage and the drawbar noseweight, if appli-
cable. The gross vehicle weight must not
exceed the gross vehicle weight rating GVWR
as specified on the vehicle identification
plate on the B-pillar on the driver's side.
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible gross
weight of a fully loaded vehicle (the weight of
the vehicle including all accessories, occu-
pants, fuel, luggage and the drawbar nose-
weight, if applicable). The gross vehicle
weight rating is specified on the vehicle
identification plate on the B-pillar on the
driver's side.

The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-
sponds to 1 psi. Another unit for tire pressure
is bar. 100 kilopascals (kPa) are the equiva-
lent of 1 bar.
Load index
In addition to the load-bearing index, the
load index may also be imprinted on the side-
wall of the tire. This specifies the load-
bearing capacity more precisely.
Curb weight
The weight of a vehicle with standard equip-
ment including the maximum capacity of fuel,
oil and coolant. It also includes the air-con-
ditioning system and optional equipment if
these are installed in the vehicle, but does

Maximum load on one tire. This is calculated by dividing the maximum axle load of one axle
by two.
PSI (pounds per square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire
width in percent.
Tire pressure
This is pressure inside the tire applying an
outward force to each square inch of the tire'ssurface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal
(kPa) or in bar. The tire pressure should only
be corrected when the tires are cold.

Tread
The part of the tire that comes into contact
with the road.
Bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 5 lbs (2.3 kilograms).
These optional extras, such as high-perform-
ance brakes, level control, a roof rack or a
high-performance battery, are not included
in the curb weight and the weight of the
accessories.
TIN (Tire Identification Number)
This is a unique identifier which can be used
by a tire manufacturer to identify tires, for
example for a product recall, and thus iden-
tify the purchasers. The TIN is made up of the manufacturer's identity code, tire size, tire
type code and the manufacturing date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of a tire.
Traction
Traction is the result of friction between the
tires and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are dis-
tributed over the tire tread. If the tire tread
is level with the bars, the wear limit of 00CDin
(1.6 mm) has been reached.
Occupant distribution
The distribution of occupants in a vehicle at
their designated seating positions.
Total load limit
Nominal load and luggage load plus 68 kg
(150 lbs) multiplied by the number of seats in

Changing a wheel
Flat tire
You can find information on what to do in the
event of a flat tire in the "Flat tire" section
(
Ypage 161).
Rotating the wheels
GWARNING
Never interchange the front and rear wheels
as they have different dimensions, e.g.
size, wheel offset etc. Otherwise, there
could be a negative effect on the road hold- ing and you could endanger yourself or oth-
ers.
!On vehicles equipped with a tire pressure
monitor, electronic components are loca-
ted in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the elec-
tronic components.
Only have tires changed at a qualified spe-
cialist workshop.
Various types of steel wheel can be fitted on
your vehicle. Some steel wheels have a red
mark in the hub cap area. The hub cap has to be
removed to see the red mark, see "Raising the
vehicle" in the "Wheel change" section
(
Ypage 197). When changing the wheels,
always fit wheels of the same type on all axles.
Always pay attention to the instructions and
safety notes when changing a wheel
(
Ypage 196).
The wear patterns on the front and rear tires
differ, depending on the operating condi-
tions. Front tires typically wear more on the
shoulders and the rear tires in the center.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressure and reac-
tivate the tire pressure monitor if necessary.
