Slide the new wheel onto the wheel hub and
push it on.
Wheels with centering by wheel bolts:
XVehicles with alloy wheels: take the short
wheel bolts that secure the steel spare wheel
out of the vehicle tool kit.
XScrew in the wheel bolts and tighten them
lightly.
For wheels with wheel nuts:
XFront wheels with wheel nut covers: press the
wheel nut covers onto the wheel nuts.
XScrew in the three wheel nuts over the fixing
discs of the wheel nut cover.
XTurn the wheel so that the wheel bolts are in
the middle of the holes.
XScrew on the rest of the wheel nuts.
XSlightly tighten all the wheel nuts.
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.
!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.
!Vehicles with Super Single tires: if you
install the spare wheel, do not exceed the
maximum speed of 40 mph (60 km/h) and do
not drive further than 65 miles(100 km).
The transmission could otherwise be dam-
aged by the difference in wheel rotation
speeds.
Tightening torque pattern
:—B
Wheel bolts or wheel nuts
XUsing the pump lever, slowly turn the lowering
screw on the jack through approximately one revolution and carefully lower the vehicle
(
Ypage 268).
XPut the jack aside.
XPull the rod with the smallest diameter off the
pump lever.
The shortened pump lever serves as a lug
wrench extension.
XStarting with the middle rod, slide the lug
wrench extension as far as it will go onto the
lug wrench.
XUsing the extended lug wrench, tighten the
wheel bolts evenly in a crosswise pattern in
the sequence indicated ( :toB).
Tighten the wheel bolts to the following tight-
ening torques:
RSteel wheel 177 lb-ft(240 Nm)
RAlloy wheel 133 lb-ft(180 Nm)
Tighten the wheel nuts to a tightening torque
of 133 lb-ft (180 Nm).
XPush the piston on the hydraulic jack in again
and close the pressure release screw.
XVehicles with all-wheel drive: turn the jack
spindle clockwise as far as it will go
(
Ypage 268).
XStow the jack and the rest of the vehicle tools
in the vehicle again.
iYou can now install the hub caps on steel
wheels with wheel bolts. The installing proce-
dure depends on whether the hub cap acts as
a trim that covers the whole wheel, or just
covers the center.
XWheel with hub cap: position the opening for
the tire valve in the hub cap over the tire valve.
XPush the edge of the hub cap with both hands against the wheel until it clicks into place.

You must observe the correct wheel and
tire dimensions as well as the wheel type.
When using a spare wheel of a different size, do
not exceed the maximum speed of 80 km/h.
General notes
!
Check the spare wheel regularly to see that
it is secure and has the prescribed tire pres-
sure.
The procedure for mounting the spare wheel is
described in "Mounting a wheel" (
Ypage 267).
The following should be checked regularly, par-
ticularly prior to long journeys:
Rthe tire pressure of the spare wheel, which
should then be corrected if necessary
(
Ypage 250).
Rthe fastenings of the spare wheel bracket.
The spare wheel is located in a spare wheel
bracket under the rear of the vehicle.
Replace the tires after 6 years at the latest,
regardless of wear. This also applies to the spare
wheel.
iIf you have mounted a spare wheel, the tire
pressure monitor (Ypage 253) will not func-
tion for this wheel. The spare wheel is not
equipped with a sensor for monitoring tire
pressure.
