Vehicle identification plate

Even if you have calculated the total load

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

(

Y

page 316).

Gross vehicle weight rating: the gross

weight of the vehicle, all passengers, load and

trailer load/noseweight (if applicable) must

not exceed the gross vehicle weight rating.
Gross Axle Weight Rating (GAWR): the

maximum permissible weight that can be car-

ried 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, load 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 approx-

imately 10 % of the gross weight of the trailer

and its load.

Only use a trailer tow hitch that has been

approved for your vehicle by Mercedes-Benz.

Comply with the manufacturer's operating

instructions for operation, care and mainte-

nance.

Overview of Tire Quality Grading

Standards

Uniform Tire Quality Grading Standards are

U.S. government specifications. Their pur-

pose is to provide drivers with uniform relia-

ble information on tire performance data. Tire

manufacturers have to grade tires using three

performance factors: : tread wear grade, ;

traction grade and = temperature grade.

These regulations do not apply to Canada.

Nevertheless, all tires sold in North America
