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 vehicle weight.
Gross axle weight rating: the maximum

permissible 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

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.
Your Mercedes-Benz has been designed

primarily to carry passengers and their

luggage. Mercedes-Benz does not

recommend towing a trailer with your vehicle.

Maximum load rating

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

(

page 304).

The actual values for tires are vehicle-

Overview of Tire Quality Grading

Standards

Uniform Tire Quality Grading Standards are

U.S. government specifications. Their

purpose is to provide drivers with uniform

reliable information on tire performance data.

Tire manufacturers have to grade tires using

three performance factors: tread wear :,

tire traction ;, and heat resistance =. All

tires sold in North America are provided with

the corresponding quality class mark on the

sidewall of the tire, even though these

regulations do not apply to Canada.
