Restarting the tire pressure monitor When you restart the tire pressure monitor,
the currently set tire pressure are taken as
reference values for monitoring.
In most cases, the tire pressure monitor
detects the new reference values
automatically, e.g. after you have:
R changed the tire pressure
R changed wheels or tires
R installed new wheels or tires
However, you can also define reference
values manually as described here.
Before restarting the tire pressure
monitor:
X Set the tire pressure to the value
recommended on the Tire and Loading
Information placard or the tire pressure
table on the B-pillar on the driver's side
(Y page 278).
Observe the notes on tire pressure when
doing so (Y page 278).
X Make sure that the tire pressure is correct
on all four wheels. Restarting the tire pressure monitor
(vehicles without steering wheel
buttons):

WARNING
Overloaded tires can overheat, causing a
blowout .Overloaded tires can also impair the
steering and driving characteristics and lead
to brake failure. There is a risk of accident.
Observe the load rating of the tires. The load
rating must be at least halfoft he GAWR of
your vehicle. Never overload the tires by
exceeding the maximum load. The Tire and Loading Information placard on the
driver’s door B-pillar
Two instruction labels on your vehicle show
the maximum possible load.
(1) Only for vehicles with a gross weight of
less than 10,000 lbs (4,536 kg):
Tire and Loading Information placard 0005
is on the B-pillar on the driver's side. Tire
and Loading Information placard 0005
shows the permissible number of
occupants and the maximum permissible
load of the vehicle. It also contains details
of the tire sizes and corresponding
pressures for tires mounted at the
factory.
(2) The vehicle identification plate is located on the base of the driver's seat. The
vehicle identification plate informs you of
the gross vehicle weight rating. It is made
up of the vehicle weight, all vehicle
occupants, the fuel and the cargo. You
can also find information about the maximum Gross Axle Weight Rating on
the front and rear axle.
The maximum gross axle weight rating is
the maximum weight that can be carried
by one axle (front or rear axle). Do not
exceed the maximum gross vehicle
weight or the maximum gross axle weight
rating for the front or rear axle.
Tire and Loading Information placard

Determining the maximum load Individual steps
The following steps have been developed as
required of all manufacturers under Title 49,
Code of U.S.F ederal Regulations, Part 575 in
accordance with the "National Traffic and
Motor Vehicle Safety Act of 1966".
X Step 1: Locate the statement "The
combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on
your vehicle's Tire and Loading Information
placard.
X Step 2: Determine the combined weight of
the driver and passengers that will be
traveling in your vehicle.
X Step 3: Subtract the combined weight of
the driver and passengers from XXX
kilograms or XXX lbs.
X Step 4: The resulting figure equals the
available amount of cargo and luggage load
capacity. For example, if the "XXX" amount
equals 1400l bs and there will be five
150 pound passengers in your vehicle, the
amount of available cargo and luggage load
capacit yis6 50 lbs (1400 0027750 (5 x 150) =
650 lbs).
X Step 5: Determine the combined weight of
luggage and cargo being loaded on the
vehicle. For reasons of safety, that weight
must not exceed the available cargo and
luggage cargo capacity calculated in step
4.
X Step 6 (if applicable): If you intend to tow
a trailer behind you rvehicle, the load on the
trailer is transferred to your vehicle. Please
consult the Tire and Loading Information
placard, to determine how this reduces the
available cargo and luggage load capacity
of your vehicle. Loading the vehicle

Further information can be found under "Towing atrailer" (Y page 173). 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 about
this can be found on the vehicle identification
plate on the drive rseat frame of your vehicle
(Y page 315).
Gross vehicle weight: the gross weight of
the vehicle, all passengers, cargo and trailer
load/noseweight (if applicable) must not
exceed the permissible gross vehicle weight.
Gross axle weight rating: the maximum
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
vehicle 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. Trailer load/noseweight
The trailer load/noseweight affects the gross
weight of the vehicle. If a trailer is attached,
the trailer load/noseweight is included in the
load along with occupants and luggage. The trailer load/noseweight is usually
approximately 10% of the gross weight of the
trailer and its load. What you should know about wheels

maximum load-bearing capacity of a tire.
Do not overload the tires by exceeding the
specified load limit. The maximum
permissible load can be found on the
vehicle's Tire and Loading Information
placard on the B-pillar on the driver's side
(Y page 286).
Example:
The load-bearing index 120 indicates a
maximum load of 3,042 lb (1,380 kg) for the
tire. If two load-bearing capacity indices are
specified (as shown above), the first number
states the load-bearing capacity for single
tires, the second number the load-bearing
capacity for twin tires. For further information
on the maximum tire load in kilograms and
pounds, see (Y page 291).290
