vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may

It must never exceed the load limit and the
Gross Vehicle Weight Rating (GVWR) for your
vehicle. The load limit and the GVWR are
specified on the placard located on the
driver’s door B-pillar (Y page 246).
In addition, the load must be distributed so
that the weight on each axle never exceeds
the Gross Axle Weight Rating (GAWR) for the
front and rear axle. The GVWR and GAWR for
your vehicle are indicated on the certification
label located on the driver’s door B-pillar
(Y page 246).
For more information, see “Tire and Loading
Information” (Y page 161).
The handling characteristics of a fully loaded
vehicle depend greatly on the load
distribution. It is therefore recommended to
load the vehicle according to the illustration
shown. The heaviest items are to be placed
towards the front of the vehicle.
i The cargo compartment is the preferred
place to carry objects. The expanded cargo
volume (Y page 128) should only be used
for items which do not fit in the cargo
compartment alone.
Please pay attention to and comply with the
following instructions when loading the
vehicle and transporting cargo:
RAlways pad off sharp edges.
RAlways place items being carried against
front or rear seat backrests, and fasten
them as securely as possible.
RThe heaviest portion of the cargo should
always be kept as low as possible against
front or rear seat backrests.
For additional safety when transporting cargo
while the rear seats are unoccupied, fasten
the outer seat belts crosswise into the
opposite side buckles :.

Restarting Advanced TPMS
GWarning!
It is the driver’s responsibility to set the tire
inflation pressure to the recommended cold
tire inflation pressure. Underinflated tires
affect the ability to steer or brake the vehicle.
You might lose control over the vehicle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a new
level (e.g. because of different load or driving
conditions). The TPMS is then recalibrated to
the current tire inflation pressures.
iCanada only:
The TPMS usually recognizes tire pressure
adjustments and sets new reference values
automatically. You can, however, restart
the TPMS manually as described.
Restart the TPMS after adjusting the tire
inflation pressure to the inflation pressure
recommended for the vehicle operating
condition. Tire pressure should only be
adjusted on cold tires. Observe the
recommended tire inflation pressure on the
Tire and Loading Information placard on the
driver’s door B-pillar. Some vehicles may have
supplemental tire pressure information for
driving at high speeds or for vehicle loads less
than the maximum loaded vehicle condition.
If such information is provided, it can be
found on the inside of the fuel filler flap.

iWhen the wheel positions have been
changed, the air pressure of a tire may be
displayed for the wrong position
temporarily. After driving for a few minutes,
the air pressure will be shown for the
correct position.
iWith a spare wheel mounted, the system
may still indicate the tire inflation pressure
of the removed road wheel for some
minutes. If this happens, keep in mind that
the indicated value where the spare wheel
is mounted does not reflect the actual
spare tire inflation pressure.
Maximum tire inflation pressure
GWarning!
Never exceed the maximum tire inflation
pressure. Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
iFor illustration purposes only. Actual data
on tires are specific to each vehicle and
may vary from data shown in above
illustration.
This is the maximum permissible tire inflation
pressure : for the tire.
Always follow the recommended tire inflation
pressure (Y page 154) for proper tire
inflation.

Weight Rating (GVWR) and the Gross Axle
Weight Rating (GAWR) for either the front or
rear axle. You can obtain the GVWR and
GAWR from the certification label. The
certification label can be found on the driver’s
door B-pillar, see the “Technical data” section
(Y page 246).
Gross Vehicle Weight Rating (GVWR): The
total weight of the vehicle, all occupants, all
cargo, and the trailer tongue load (if
applicable) must never exceed the GVWR.
Gross Axle Weight Rating (GAWR): The total
allowable weight that can be carried by a
single axle (front or rear).
To assure that your vehicle does not exceed
the maximum permissible weight limits
(GVWR and GAWR for front and rear axle),
have the loaded vehicle (including driver,
passengers and all cargo and, if applicable,
trailer fully loaded) weighed on a suitable
commercial scale.
Trailer tongue load
The tongue load of any trailer is an important
weight to measure because it affects the load
you can carry in your vehicle. If a trailer is
towed, the tongue load must be added to the
weight of all occupants riding and any cargo
you are carrying in the vehicle. The tongue
load typically is 10% of the trailer weight and
everything loaded in it.
If an approved Mercedes-Benz trailer hitch is
available for your G-Class vehicle model,
consult the instructions included in the trailer
hitch kit for vehicle towing capacity,
permissible gross trailer weight, trailer
tongue weight rating, and instructions on
loading and towing a trailer.
Maximum tire loadGWarning!
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.
iFor illustration purposes only. Actual data
on tires are specific to each vehicle and
may vary from data shown in above
illustration.
The maximum tire load rating : is the
maximum weight the tires are designed to
support.
For more information on tire load rating, see
(Y page 169).
For information on calculating total and cargo
load capacities, see (Y page 162).
Direction of rotation
Unidirectional tires offer added advantages,
such as better hydroplaning performance. To
benefit, however, you must make sure the
tires rotate in the direction specified.
An arrow on the sidewall indicates the
intended direction of rotation of the tire.
Spare wheels may be mounted against the
direction of rotation (spinning) even with a
unidirectional tire for temporary use only until
