2016 MERCEDES-BENZ G-Class change wheel

ted. Check the tire pressure and reactivate the
tire pressure monitor (Ypage 268)if necessary.
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk 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 a cool, dry
and preferably dark place. Protect the tires from
oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
GWARNING
When you remove the spare wheel from the
spare wheel bracket, the vehicle’s weight dis-
tribution changes. If the vehicle is already
raised, the jack could tip over. There is a risk
of injury.
Remove the spare wheel from the spare wheel
bracket before lifting the vehicle.
XPrepare the vehicle as described
(Ypage 250).
XRemove the vehicle tool kit and the jack
(Ypage 248).
XSecure the vehicle to prevent it from rolling
away.
XRemove the spare wheel from the spare wheel
bracket (Ypage 249).
iVehicles without a spare wheel or emer-
gency spare wheel are not equipped with a
tire-change tool kit at the factory. For more
information on which tools are required to
perform a wheel change on your vehicle e.g. lug wrench or jack, consult an authorized
Mercedes-Benz Center.
Securing the vehicle to prevent it from
rolling away
XOn level ground:
place chocks or other suit-
able items under the front and rear of the
wheel that is diagonally opposite the wheel
you wish to change.
XOn downhill gradients: place chocks or
other suitable items in front of the wheels of
the front and rear axle.
Raising the vehicle
GWARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
!The jack is designed exclusively for jacking
up the vehicle at the jacking points. Other-
wise, your vehicle could be damaged.
Observe the following when raising the vehicle:
RTo raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If used incorrectly, the
jack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It is not suited for performing main-
tenance work under the vehicle.
RAvoid changing the wheel on uphill and down- hill slopes.
RBefore raising 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 a firm, flat and
non-slip surface. On a loose surface, a large,
load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
RDo not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
282Changing a wheel
Wheels and tires

be able to achieve its load-bearing capacity
due to the restricted height.
RMake sure that the distance between 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 a door when the vehicleis raised.
RMake sure that no persons are present in the
vehicle when the vehicle is raised.
XUsing lug wrench :, loosen the bolts on the
wheel you wish to change by about one full
turn. Do not unscrew the wheel bolts com-
pletely.
Pump lever ;
XAssemble the pump lever for the jack. It can
be found with the vehicle tool kit
(
Ypage 248).
XTurn pressure release screw =clockwise as
far as it will go using notch ;on the pump
lever.
Pressure release screw =is closed.
iDo not turn pressure release screw =by
more than one to two revolutions. Otherwise,
hydraulic fluid could escape.
XSet jack :on solid ground.
XPosition jack :on the axle carrier tube ;of
the front or rear axle. Jack :must always
stand vertically, even on slopes.
Make sure that jack :is correctly positioned
under axle carrier tube ;. The front or rear
axle must sit securely in the recess of jack :.
XRaise the vehicle by pumping in the direction
of the arrow until the tire is 1.2 in (3 cm) off
the ground at the most.
Removing a wheel
!Do not place wheel bolts in sand or on a dirty
surface. The bolt and wheel hub threads could
otherwise be damaged when you screw them
in.
XUnscrew the wheel bolts.
XRemove the wheel.
Changing a wheel283

Mounting a new wheel
GWARNING
Oiled or greased wheel bolts/wheel nuts and
damaged wheel bolt/wheel nut/wheel hub
threads can cause wheel bolts/wheel nuts to
come loose. As a result, you could lose a
wheel while driving. There is a risk of an acci-
dent.
Never oil or grease wheel bolts/wheel nuts. In
the event of damage to the threads, contact a
qualified specialist workshop immediately.
Have the damaged wheel bolts/wheel nuts or
hub threads replaced/renewed. Do not con-
tinue driving.
GWARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
!To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.
Always pay attention to the instructions and
safety notes in the "Changing a wheel" section
(
Ypage 281).
XClean the wheel and wheel hub contact sur-
faces.
XPlace the new wheel on the wheel hub and
push it on.
XTighten the wheel bolts until they are finger-
tight.
Lowering the vehicle
GWARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
XOpen the pressure release screw on the jack
using the pump lever (Ypage 282) by approx-
imately one turn.
XLower the vehicle until it is once again stand-
ing firmly on the ground.
XPlace the jack to one side.
XTighten the wheel bolts evenly in a crosswise pattern in the sequence indicated (: toA).
The specified tightening torque is 96 lb-ft
(130 Nm).
XDisassemble the pump lever.
XPush the jack piston back in and close the
drain plug.
XUse the bolts to secure the faulty wheel to the
spare wheel bracket (Ypage 249).
XStow the jack and the vehicle tools in the
vehicle again.
XCheck the tire pressure of the newly installed
wheel and adjust it if necessary.
A table with the tire pressures for your vehicle can be found on the B-pillar on the driver's
side.
Wheel and tire combinations
General notes
GWARNING
If wheels and tires of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tires with those
that fulfill the specifications of the original
part.

Maximum gradient-climbing capabil-
ity
Note that the vehicle's gradient-climbing capa-
bility depends on the off-road conditions and theroad surface conditions.
On good road surfaces the maximum gradient-
climbing capability of your vehicle is 100%,
which corresponds to an approach/departure
angle of 45°.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep ter-
rain.
iIf the load on the front axle is reduced when
pulling away on a steep uphill slope, the front
wheels have a tendency to spin. 4ETS detects this and brakes the wheels accordingly. The
rear wheel torque is increased, making it eas-
ier to drive off.
For further information about the maximum gra-
dient climbing ability, see (
Ypage 140).
