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

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 263).
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 263).
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.
Make sure the hub cap retaining catches
engage on the steel wheel.
XWheel with central hub cap: position the
retaining lugs of the central hub cap over the
wheel bolts.
XHit the center of the hub cap to engage it on
the wheel.
XSecure the faulty wheel in the spare wheel
bracket (Ypage 269).
XVehicles with Super Single tires: transport the
defective rear wheel in the load area. The rear wheel is too large for the spare wheel bracket.
XCheck the tire pressure of the newly mounted
wheel and adjust it if necessary.
Observe the recommended tire pressure
(
Ypage 246).
XRetighten the wheel bolts or wheel nuts to the
specified tightening torque after the vehicle
has been driven for 30 miles (50 km).
When using a wheel or spare wheel with a new or newly painted wheel rim, have the wheel bolts or
nuts retightened again after approximately 600
to 3,000 miles (1,000 to 5,000 km). Observe the
specified tightening torque.
