Use the jack only for wheel-
changing. Never attempt to raise a

different type of vehicle or any other
load with the jack, or injury and damage
to property could result.
For safety reasons, have the wheel stud
tightening torque checked without
delay, using a suitable calibrated torque
wrench – correct tightening torque =
120 Nm (88.5 lb ft).

When replacing a wheel in the spare
wheel well, make sure that the central
threaded rod in the well is not bent or
damaged.

If the car is fitted with alloy wheels not
of original BMW pattern, note that dif-
ferent wheel studs may be needed.

Have a flat tyre repaired as soon as
possible, and the wheel and tyre rebal-
anced before fitting.

Driving with the compact spare
wheel fitted

Drive very carefully and do not exceed
a road speed of 80 km/h (50 mph).

The car might handle differently, for
example it might be less stable when
the brakes are applied, braking dis-
tances might be longer, or self-steering

effects might be different when close to
the handling limit. These characteristics
become more evident if the car's other
wheels are fitted with winter tyres.

Do not fit more than one compact
spare wheel. Fit a conventional

wheel and tyre again at the earliest pos-
sible opportunity.

Driving with the spare wheel*
fitted

The spare wheel might not be the
same size as the other wheels:

this applies to certain wheel/tyre com-
binations. The spare wheel is suitable
for all the car's load and speed ranges.
You should, however, refit the original
wheel and tyre at the earliest possible
opportunity.

To remove:

1. Turn cap 1 slightly to the left with the

wheel stud wrench, and take it off

insert it into the wheel stud

3. Unscrew wheel stud 2.

After inserting and tightening the wheel
