2006 MERCEDES-BENZ G500 wheel bolts

252 Operation
Tires and wheels
See an authorized Mercedes-Benz Light
Truck Center for information on tested and
recommended rims and tires for summer
and winter operation. They can also offer
advice concerning tire service and
purchase.
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous
damage cannot always be recognized on
retreads. The operating safety of the
vehicle cannot be assured when such tires
are used.Important guidelines

Only use sets of tires and rims of the
same type and make.

Tires must be of the correct size for the
rim.

Break in new tires for approximately
60 miles (100 km) at moderate
speeds.

Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire inflation pressure loss and
damage to the tire beads.

If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.

Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths under
1/8in (3 mm).

When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Warning!G
Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the
original part. See an authorized
Mercedes-Benz Light Truck Center for fur-
ther information. If incorrectly sized rims
and tires are mounted:

The wheel brakes or suspension
components can be damaged.

The operating clearance of the wheels
and the tires may no longer be correct.
Warning!G
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly an
accident.

277 Operation
Tires and wheels
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder
wear on front tires and tread center wear
on rear tires).
Thoroughly clean the mounting face of
wheels and brake disks, i.e. the inner side
of the wheels/tires, during each rotation.
Check for and ensure proper tire inflation
pressure.
For information on wheel change, see “Flat
tire” (
page 348).
Warning!G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
97 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

349 Practical hints
Flat tire
Mounting the spare wheel
Prepare the vehicle (page 348).
Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:
Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
Always try lifting the vehicle using the jack
on a level surface. However, should cir-
cumstances require you to do so on a hill,
place the wheel chocks as follows:
Place chocks on the downhill side
blocking both wheels of the axle not
being worked on.
Wheel wrench
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench).
Warning!G
The jack is designed exclusively for jacking
up the vehicle under the axle housing. To
help avoid personal injury, use the jack only
to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is sup-
ported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always firmly set parking brake and block
wheels before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Make sure the jack is posi-
tioned correctly under the axle housing. Al-
ways lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
If the vehicle is not raised as described, it
could slip off the jack as a result of vibra-
tions (e.g. opening or closing a door or the
tailgate).

351 Practical hints

Removing the wheel
Remove the wheel bolts.
Remove the wheel.Mounting the new wheel
Clean contact surfaces of wheel and
wheel hub.
Push the wheel onto the wheel hub and
press firmly.
Insert wheel bolts and tighten them
slightly.
!
Do not place wheel bolts in sand or dirt.
This could result in damage to the bolt
and wheel hub threads.
Warning!G
Make sure no one is injured when removing
the wheel.
Grip wheel from the sides.
Keep hands from beneath the wheel.
Warning!G
Always replace wheel bolts that are dam-
aged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be re-
paired immediately. Do not continue to drive
under these circumstances! Contact an au-
thorized Mercedes-Benz Light Truck Center
or call Roadside Assistance.
Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident.
Make sure to use the correct wheel bolts.
Warning!G
Use only genuine equipment
Mercedes-Benz wheel bolts. Other wheel
bolts may come loose.
Do not tighten the wheel bolts when the ve-
hicle is raised. Otherwise the vehicle could
tip over.

352 Practical hints

Lowering the vehicle
Using the pump handle, open the low-
ering screw on the jack approximately
one turn (
page 350).
The vehicle is resting fully on its own
weight.
Remove the jack.
After use, disassemble pump handle
(
page 350) and store jack in the des-
ignated storage compartment
(
page 324).
1-5 Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 97 lb-ft
(130 Nm).Press the jack piston in again and close
the lowering screw. Store the jack
(
page 324) and the other vehicle
tools (
page 323).
After changing the wheel, secure the
damaged wheel on the spare wheel
mounting bracket (
page 326). Make
sure the wheel cannot come loose.
Check the tire inflation pressure and
correct it if necessary.
A table with the tire pressure values for
your vehicle is located on the fuel filler
flap.
Warning!G
Have the tightening torque checked after
changing a wheel as soon as possible. The
wheels could come loose if they are not
tightened to a torque of 97 lb-ft (130 Nm).
