Jacking up vehicle
The jacking points for the car jack are located in
the positions shown.
1. Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base rests on the ground
perpendicularly beneath the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.
<
2. Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.
3. Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1. Unscrew the lug bolts and remove the
wheel.
2. Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3. Position the new wheel or spare wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4. Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5. Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1. Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
88.5 lb ft/120 Nm.
<
2. Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.

3. Initialize the Flat Tire Monitor, refer to
page

mission, refer to After changing wheels/
tires on page
201 .
4. Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
