Tire pressure table inside the fuel filler flap
(example: Cargo Van)
You will find the recommended tire pressure
for various operating conditions on the inside
of your vehicle's fuel filler flap
(Y page 137)
and under "Tire pressure table" (Y page 289).
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid
for that tire size. Example: Cargo Van vehicle loads
Example: Passenger Van vehicle loads
:
Partially laden vehicle
; Fully laden vehicle
For the Passenger Van, the vehicle loads are
defined in the table as different numbers of
passengers and amounts of luggage. The
actual number of seats may vary – for more
information, please refer to the vehicle's regis-
tration documents.
The tire pressure value given for partly laden
vehicles are minimum values which offer you
good ride comfort. They are not for towing
trailers.
You can also use the tire pressure values for a
fully laden vehicle. These are always permitted
and admissible. However, in a partially laden
vehicle, the ride is not as comfortable and fuel
consumption is only minimally reduced. In
addition, wear is greater in the center of the
tire tread.
For towing trailers, the applicable value for the
rear tires is the maximum tire pressure value
stated in the table inside the fuel filler flap. Tire pressure

Determining the maximum load Individual steps
The following steps have been developed as
required of all manufacturers under Title 49,
Code of U.S. Federal Regulations, Part 575 in
accordance with the "National Traffic and
Motor Vehicle Safety Act of 1966".
(1) Locate the statement "The combined weight of occupants and cargo should
never exceed XXX kg or XXX lbs." on your
vehicle's placard. on your vehicle's plac-
ard.
(2) Determine the combined weight of the driver and passengers that will be riding in
your vehicle.
(3) Subtract the combined weight of the driver and passengers from XXX kg or XXX
lbs.
(4) The resulting figure equals the available amount of cargo and luggage load capa-
city. For example, if the "XXX" amount
equals
1400 lbs and there will be five290
Loading the vehicle
Wheels and tires

150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is
650 lbs. (1400 Ò 750 (5 x
150) = 650 lbs.).
(5) Determine the combined weight of lug- gage and cargo being loaded on the vehi-
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.
The vehicle placard named in Step 1 is the Tire
and loading information placard for your vehi-
cle.
Please note that not all vehicles are approved
for trailer operation. Trailer operation is only
permitted when a trailer hitch is installed
(Y page
315). If in doubt, please consult a
qualified specialist workshop. Example: Steps 1 to 3
The following table shows examples of how to calculate total load and cargo capacities with vary-
ing seating configurations and number and size of occupants. The following examples use a max-
imum load of
1500 lbs (680 kg). This is for illustration purposes only. Make sure you are

You can find further information under: "Trailer tow hitch"
(Y page 315).Vehicle identification plate
Even if you have calculated the total load care-
fully, you should still make sure that the per-
missible gross weight and the gross axle
weight rating of your vehicle are not exceeded.
This data can be found on the vehicle identifi-
cation plate on the B-pillar of your vehicle
(Y page
304).
Gross Vehicle Weight Rating (GVWR): the
gross weight of the vehicle, all occupants, load
and trailer load/trailer tongue load (if applica-
ble) must not exceed the permissible gross
vehicle weight.
Gross Axle Weight Rating (GAWR): the maxi-
mum permissible load 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 rat-
ing), have your loaded vehicle (including driver,
occupants, load, and full trailer load if applica-
ble) weighed on a suitable vehicle weigh-
bridge. Trailer load/trailer tongue load
The trailer load/trailer tongue load affects the
gross weight of the vehicle. If a trailer is
attached, the trailer load/trailer tongue load is
included in the load along with occupants and
luggage. The trailer load/trailer tongue load is
usually approximately
10% of the gross weight
of the trailer and its load. What you should know about wheels

applicable). The permissible gross weight is
specified on the vehicle identification plate on
the B-pillar on the driver's side (Y page 304).
Maximum weight of the laden vehicle
The maximum weight is the sum of:
R the curb weight of the vehicle
R the weight of the accessories
R the load limit
R the weight of the factory installed optional
equipment
Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa are the
equivalent of 1 psi. Another tire pressure unit
is bar. 100 kilopascals (kPa) are the equivalent
of 1 bar. Load index
In addition to the load bearing index, a load
index can be stamped onto the sidewall of the
tire. It specifies the load-bearing capacity of
the tire more precisely.
Curb weight The weight of a vehicle with standard equip-
ment including the maximum filling capacity of
fuel, oil, and coolant. It also includes the air-
conditioning system and optional equipment if
these are installed on the vehicle, but does not
include passengers or luggage.
Maximum tire load
The maximum tire load in kilograms or pounds
is the maximum weight for which a tire is
approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one

by dividing the maximum axle load of one axle
by two.
PSI (Pounds per square inch)
Standard unit of measurement for tire pres-
sure.
Aspect ratioRelationship between tire height and width in
percent.
Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's surface.
Tire pressure is specified in pounds per square
inch (psi), in kilopascal (kPa) or in bar. Tire
pressure should only be corrected when the
tires are cold.

Weight of optional extras The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg
(5 lbs). These
optional extras, such as high-performance
brakes, a roof rack or a high-performance bat-
tery, are not included in the curb weight and
the weight of the accessories.
TIN (Tire Identification Number) A unique identification number 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 composed of
the manufacturer identification code, tire size,
tire model code and 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.
TWR (permissible trailer drawbar load)
The TWR is the maximum permissible weight
that may act on the ball coupling of the trailer
tow hitch.
Wear indicator Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of á in (1.6 mm)
has been reached. Distribution of the vehicle occupants
The distribution of vehicle occupants over des-
ignated seat positions in a vehicle.
Maximum permissible payload weightNominal load and goods/luggage load plus
68 kg (150 lbs) multiplied by the number of
seats in the vehicle. Changing wheels
Rotating the wheels
! On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop.
Always observe the instructions and safety
notes under "Mounting a wheel"
(Y page
298).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the tires according to the intervals
in the tire manufacturer's warranty book in
your vehicle documents. If no warranty book is
available, the tires should be rotated every
3,000 to 6,000 miles (5,000 to 10,000 km) or
earlier if tire wear requires. Do not change the
direction of rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Avoid oily or greasy cleaning
agents.
Check the tire pressure and reactivate the tire
pressure monitor if necessary. Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of
hydroplaning. You will only gain these benefits
if the correct direction of rotation is observed. Changing wheels
