Changing a wheel8. Remove accumulations of mud and
dirt from the mounting surfaces of
the wheel and hub. Clean the lug
bolts
9. Position the new wheel or the
space saver spare tire on the hub
and screw at least two lug bolts
finger-tight into opposite bolt holes
10. Screw in the remaining lug bolts
and screw in all the bolts in a diag-
onal pattern
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts securely in a
diagonal pattern
13. Wheels with full wheel covers
*:
Place the wheel cover with the
valve opening (arrow) over the
valve. Use both hands to press the
cover securely onto the rim
14. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Tire Pressure Monitor
(RDC)/Flat Tire Monitor:
After mounting the spare tire or
correcting the tire inflation pres-
sure, reactivate the system, refer to
page 83 or 85.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire, since this could
damage the cover.<
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
tightness of the lug bolts checked with
a calibrated lug wrench [torque specifi-
cation: 72 lb ft (72 100 Nm] at the
earliest opportunity.<
When storing a wheel in the spare tire
recess take care to avoid bending the
threaded rod.
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.
