2017 MERCEDES-BENZ G-Class tire pressure

!On vehicles equipped withatire pressure
monitor, electronic componentsa re 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 aqualified spe-
cialist workshop.
Alwayso bserve the instructionsa nd safety
notes under "Installing awheel" (
Ypage 270).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000 km). Depending on tire wear, this may
be required earlier. Do not change the direction
of wheel rotation.
Cleant he contact surfaces of the wheel and the
brake disc thoroughly every time awheel is rota-
ted. Check the tire pressure and reactivate the
tire pressure monitor if necessary (
Ypage 259).
Direction of rotation
Tires with aspecified direction of rotation have
additional benefits, e.g. if there is arisk of hydro-
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
You may mount the spare wheel against the
direction of rotation. Adhere to the time restric-
tion on use as well as the speed limitation speci-
fied on the spare wheel.
Storing wheels
Store tires that are not being used in acool, dry
and preferably dark place. Protect the tires from
oil, grease, gasoline and diesel.

Observe the following when raising the vehi-
cle:
RTo raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz.Ifused incorrectly, the
jack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold the
vehicle for ashort time while awheel is being
changed. It must not be used for performing
maintenance work under the vehicle.
RAvoid changin gthe wheel on uphill and down-
hill slopes.
RBeforer aising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Do not disengage the
parking brake while the vehicle is raised.
RThe jack must be placed on afirm, flat and
non-slip surface. On aloose surface, alarge,
flat, load-bearing underlay must be used. On a
slippery surface, anon-slip underlay must be
used, e.g. rubber mats.
RDo not use wooden blocks or similar objects
as ajack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
RMake sure that the distanc ebetween the
underside of the tires and the ground does not
exceed 1.2 in (3 cm).
RDo not place your hands or feet under the
raised vehicle.
RDo not lie under the vehicle.
RDo not start the engine when the vehicle is
raised.
RDo not open or close adoor when the vehicle
is raised.
RMake sure that no persons are present in the
vehicle when the vehicle is raised.

tionin gsensors for the tire pressure monitor.
Wheel and tire combinations
You can ask for information regarding permitted
wheel/tire combinations at an authorized
Mercedes-Benz Center.
!For safety reasons, Mercedes-Benz recom-
mends that you only use tires, wheels and
accessories which have been specifically
approved by Mercedes-Benz for your vehicle.
These are specially adapted to the various
driving safety systems, such as ABS or ESP
®.
Only use tires, wheels and accessories tested
and recommended by Mercedes-Benz.C er-
tain characteristics, such as handling, vehicle
noise emissions, fuel consumption, etc. may
otherwise be adversely affected. In addition,
other wheel sizes may cause the tires to rub
against the vehicle body and axle compo-
nents, when under load. This may result in
damage to the tire or to the vehicle.
Mercedes-Benz is not responsible for any
damage caused by using tires, wheels or
accessories different from those recommen-
ded.
Information on tires, wheels and permissible
combinations can be obtained at aqualified
specialist workshop.
!Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz,s ince previ-ous damage cannot alwaysbed
etected on
retreaded tires. As aresult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if
you have no information about their previous
usage.
The recommended pressures for various oper-
ating conditions can be found:
Ron the Tire and Loading Information placard
on the B-pillar on the driver's side
Rin the tire pressure table in the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
(
Ypage 254).
Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicle document wallet.
Notes on equipping the vehicle:
