additional precautions to secure the
vehicle from rolling.
3. Loosen the lug bolts 1/2 a turn
4. Set up the jack beneath the jacking
point closest to the flat tire. Ensure that the
entire surface of the jack's base is in firm
contact with the ground and that the jack
itself is standing completely vertical (not
tilted), and that the fitting on the top of the
jack will align with the rectangular recess
on the vehicle when you raise it, refer to
illustration
5. Jack the vehicle up until the wheel you
are changing is raised from the ground
6. Unscrew the lug bolts and remove the
wheel
7. Remove accumulations of mud or dirt
from the mounting surfaces of the wheel
and hub. Clean the lug bolts
8. Position the spare wheel. Secure the
wheel by turning at least two lug bolts into
opposite bolt holes
9. Screw in the remaining lug bolts.
Tighten all the bolts securely in a diagonal
pattern
10. Lower the jack and remove it from
beneath the vehicle.
11. Tighten the lug bolts in a diagonal
pattern
12. Check and correct the tire inflation
pressure at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.
Vehicles with RDC Tire Pressure Monitor:
After mounting a spare tire or correcting
the inflation pressure(s) always remember
to reinitialize the system, refer to page
92 .
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 safety, always have the lug bolts
checked with a calibrated torque wrench to
ensure that they are tightened to the spec-
ified torque of 140 Nm as soon as
possible.

Reverse the removal sequence to store the
wheel and tools in the vehicle.
When you mount wheels other than Orig-
inal BMW light-alloy wheels, different lug
bolts may also be required.
Always have damaged tires replaced and
the wheel and tire assembly rebalanced at
the earliest possible opportunity.
