surface of the front tire on the side
opposite the side being raised. If the
vehicle is parked on a downward slope,
place the wheel chock securely in front
of the tire. If the wheel must be changed
on a surface with a more severe slope,
take additional precautions to secure
the vehicle from rolling

Loosen the lug bolts 1/2 a turn

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

Jack the vehicle up until the wheel you
are changing is raised from the ground

Unscrew the lug bolts and remove the

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.

After mounting the spare wheel or correct-

Flat Tire Monitor, refer to page

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
as soon as possible to ensure that they are
tightened to the specified torque.
The tightening torque is 101 ft-lb/
140 Nm.

Reverse the removal sequence to store the
wheel and tools in the vehicle.

When you mount wheels other than Genu-
ine 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.

Driving with the spare tire

On certain wheel-tire combinations,
the size of the spare tire deviates from

that of the rest of the tires. The spare tire is
fully capable of running in all load and
speed ranges. However, to recreate the
original conditions, the tire should be
replaced as soon as possible.
