Even if you have calculated the total cargo care-
fully, 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 362).
Permissible Gross Vehicle Weight Rating
(GVWR): the gross weight of the vehicle, all pas-
sengers, load and trailer load/noseweight (if
applicable) must not exceed the permissible
gross vehicle weight.
Gross Axle Weight Rating (GAWR): the maxi-
mum 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, occu-
pants, 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 8% of
the gross weight of the trailer and its cargo. Loading the vehicle

Not all tires with the M+S marking provide
the driving characteristics of winter tires. In
addition to the M+S marking, winter tires also
have the 004Dsnowflake symbol on the tire
wall. Tires with this marking fulfill the require- ments of the Rubber Manufacturers Associa-
tion (RMA) and the Rubber Association of
Canada (RAC) regarding the tire traction on
snow. They have been especially developed
for driving on snow.
An electronic speed limiter prevents your vehi-
cle from exceeding the following speeds:
R All vehicles (except Mercedes-AMG GLS 63):
130 mph (210 km/h)
R Mercedes-AMG GLS 63: 155 mph (250 km/h)
R Mercedes-AMG GLS 63 with increased top
speed: 174 mph (280 km/h)
The speed rating of tires mounted at the factory 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 (Y page 377).
Further information about reading tire data can
be obtained from any qualified specialist work-
shop. Load index In addition to the load bearing index, load
index
0043may be imprinted after the letters that
identify speed index 0084on the sidewall of the
tire (Y page 367).
R If no specification is given: no text (as in the
example above), represents a standard load

DOT, Tire Identification Number (TIN) US tire regulations stipulate that every tire man-
ufacturer or retreader must imprint a TIN in or on the sidewall of each 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 identifica-
tion code 0044, tire size 0087, tire type code 0085and
manufacturing date 0083.
DOT (Department of Transportation): tire
symbol 0043marks that the tire complies with the
requirements of the U.S. Department of Trans-
portation.
Manufacturer identification code: manufac-
turer identification code 0044provides details on
the tire manufacturer. New tires have a code
with two symbols. Retreaded tires have a code
with four symbols.
For further information about retreaded tires,
see (Y page 377).
Tire size: identifier0087describes the tire size.
Tire type code: tire type code0085can be used by
the manufacturer as a code to describe specific
characteristics of the tire.
Date of manufacture: date of manufacture0083
provides information about the age of a tire. The
first and second positions represent the week of manufacture, starting with "01" for the first cal-
endar week. Positions three and four represent
the year of manufacture. For example, a tire that
is marked "3214" was manufactured in week 32
in 2014. i
