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.
To ensure continued safety, have the
lug bolts checked with a calibrated
torque wrench [torque specification
72 lb-ft (100 Nm)] at the earliest
opportunity.<
When storing the wheel, take care to
ensure that you do not damage the
retaining pin in the spare tire recess.
If light-alloy wheels other than original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Protect valve inserts against dirt using
screw-on valve stem caps. Dirty valve
stems frequently lead to slow pressure
loss.
