2012 MERCEDES-BENZ G-Class trailer

X
Step 5: Determine the combined weight of
luggage and cargo being loaded on the
vehicle.
That weight may not safely exceed
the available cargo and luggage load
capacity calculated in step 4.
X Step 6 (if applicable): 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 ( Y page 256).254

Further information can be found under "trailer load/noseweight"
(Y

page 256).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 252).
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 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.
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
maintenance. Maximum load rating
G
WARNING
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar . Overloading the tires
can overheat them, possibly causing a
blowout.

Overloading the tires can also result
in handling or steering problems, or brake
failure. 256
Maximum load rating
Wheels and tires

Increased vehicle weight due to
optional equipment
This is the combined weight of all standard
and optional equipment available for the
vehicle, regardless of whether it is actually
installed on the vehicle or not. Wheel rim
This is
the part of the wheel on which the tire
is mounted. GAWR (Gross Axle Weight Rating)
The GAWR

is the maximum gross axle weight
rating. The actual load on an axle must never
exceed the gross axle weight rating. The
gross axle weight rating can be found on the
vehicle identification plate on the B-pillar on
the driver's side. Speed index
The speed index is part of the tire
identification. It

specifies the speed range for
which the tire is approved. GTW (Gross Trailer Weight)
The GTW is the sum of the weight of a trailer
and the weight of the load, luggage,
accessories etc. on the trailer. GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight
of the vehicle including fuel, tools, the spare
wheel, accessories installed, occupants,
luggage and the drawbar noseweight if
applicable. The

gross vehicle weight must not
exceed the gross vehicle weight rating GVWR
as specified on the vehicle identification plate
on the B-pillar on the driver's side. GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permitted gross
weight of

the fully laden vehicle (weight of the
vehicle including all accessories, occupants,
fuel, luggage and the drawbar noseweight if
applicable). The gross vehicle weight rating is
specified on the vehicle identification plate on
the B-pillar on the driver's side. Maximum
weight of the laden vehicle
The maximum weight is the sum of the curb
weight of the vehicle, the weight of the
accessories, the maximum load and the
weight of

the optional equipment installed at
the factory. Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa is the
equivalent of 1 psi

. Another unit for tire
pressure is bar. 100 kilopascal (kPa) is the
equivalent of 1 bar. Load index
In addition

to the load bearing index, the load
index may also be imprinted on the sidewall
of the tire. This specifies the load bearing
capacity more precisely. Curb weight
The weight of a vehicle with standard
equipment, including the maximum capacity
of fuel, oil and coolant and also includes the
air-conditioning system and optional
equipment if these are installed on the
vehicle, but does not include passengers or
luggage. Definition of terms for tires and loading
263Wheels and tires Z

TWR (permissible trailer drawbar
noseweight)
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
distributed over

the tire tread. If the tire tread
is level with the bars, the wear limit of 1
/ 16 in
(1.6 mm) has been reached. Distribution of the vehicle occupants
Distribution of vehicle occupants over
designated seat positions in a vehicle. Maximum permissible payload
weight
Nominal load and luggage load plus
68 kilograms (150 lb) multiplied by the
number of seats in the vehicle. Changing a wheel
Flat tire
The "Roadside Assistance" section
(
Y
page

226) contains information and notes
on how to deal with a flat tire. It also provides
instructions on changing a wheel or mounting
the spare wheel. Interchanging the wheels
G
WARNING
Rotate front and rear wheels only if the tires
are of the same dimension.
If your vehicle is equipped with mixed-size
tires (different

tire dimensions front vs. rear),
tire rotation is not possible. G
WARNING
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
96 lb-ft (130 Nm).
Only use

genuine Mercedes-Benz wheel bolts
specified for your vehicle's rims.
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 wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If this is not
available, the tires should then be replaced
every 3000 to 6000 miles
(5000 to 10,000 km), or earlier if the tire wear
requires this. Do not change the direction of
wheel rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tire pressure and
reactivate the tire pressure monitor
(Y page 249) if necessary.
Information on changing a wheel and
mounting the spare wheel ( Y page 226).
! 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
specialist workshop. 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 Changing a wheel
