Wheels with centering by wheel bolts:
Wheel bolt for alloy wheel
:
Wheel bolt for steel wheel
;
! For a steel wheel, only use the short wheel
bolts to install the steel spare wheel. Using
other wheel bolts to install the steel spare
wheel could damage the brake system.
X
Screw in the wheel bolts and tighten them
lightly.
i On vehicles with alloy wheels, you will find
short wheel bolts suitable for the steel
spare wheel in the vehicle tool kit.
For wheels with wheel nuts:
X
On the front wheels, push the wheel nut
cover onto the wheel bolts.
X
Screw in three wheel nuts over the fixing
discs of the wheel nut cover.
X
Turn the wheel so that the wheel bolts are
in the middle of the holes.
X
Screw on the rest of the wheel nuts.
X
Slightly tighten all the wheel nuts.

Lowering the vehicle

X
Open the pressure release screw on the
jack with pump lever slowly by one turn
( Y page 230).
X
Carefully lower the vehicle.
X
Put the jack aside.
X
Pull the rod with the smallest diameter off
the pump lever.
The shortened pump lever serves as a lug
wrench extension.
X
Starting with the middle rod, slide the lug
wrench extension as far as it will go onto
the lug wrench.
! Only use the jack pump lever middle rod
and the rod with the largest diameter as a
lug wrench extension. Only slide the middle
rod as far as it will go onto the lug wrench.
The rods may otherwise bend and be
distorted to such an extent that they can
no longer be used as a pump lever for the
jack.
Tightening torque pattern
Wheel bolts or wheel nuts

X
Tighten all the wheel bolts or wheel nuts
evenly in the sequence indicated using the
extended lug wrench.
! The tightening torque is:
for wheel bolts: 177 lb-ft (240 Nm) (steel
R
wheel)/133 lb-ft (180 Nm) (alloy wheel)
for wheel nuts: 133 lb-ft (180 Nm)

You can now install the hub caps on steel
wheels with wheel bolts. The installing
procedure depends on whether the hub cap
covers the whole wheel or just the center.
! With a hub cap that covers the whole
wheel, make sure the opening for the tire
valve is positioned over the valve.
