Jacking up vehicle
1. Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base perpendicularly con-
tacts the ground under 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 drawing inset.
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. Clean the lug bolts.
3. Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes. When you
mount wheels other than Genuine 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 jack and remove it 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
101 lb ft/140 Nm.<
2. Stow the defective wheel in the cargo area.
3. Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4. Reinitialize the Flat Tire Monitor
*
or reset
the Tire Pressure Monitor
*
, refer to
pages 54, 55.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5. Replace the defective tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as soon as
possible.<
