2. Secure the vehicle from rolling:
Place the wedge against the rear
surface of the front tire on the side
opposite the side being raised. If the
vehicle is parked on a downward
slope, place the wedge securely in
front of the tire. If the wheel must be
changed on a surface with a more
severe slope, take additional precau-
tions to secure the vehicle from
rolling
3. Wheels with full wheel covers
*:
Reach into the ventilation openings
and pull the cover off4. Loosen the lug bolts by rotating half
a turn
5. Position the jack at the jacking point
closest to the flat tire (arrows) with
the jack base vertically below the
jacking point and the entire surface
of the head of the jack will move into
the square recess of the jacking
point (refer to the detail in the next
illustration) when the jack is cranked

Changing a wheel8. Remove accumulations of mud or
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.
Screw in all the bolts in diagonal
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
pages 73, 75.
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 torque bolts checked
with a calibrated lug wrench [torque
specification: 72 lb ft (100 Nm)] at the
earliest opportunity.<
When storing a wheel in the spare tire
recess take care to avoid bending the
threaded rod.
If the original BMW light-alloy wheels
have been replaced with other light-
alloy wheels, different lug bolts may be
required.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.

OverviewControlsMaintenanceRepairsDataIndex
Battery FusesMaintenanceThe battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.
Please consult your BMW center
whenever you have any questions
concerning the battery. Since the
battery is absolutely maintenance-free,
the following is for your information
only.<
Never disconnect the battery
when the engine is running; the
ensuing voltage surge would seriously
damage the vehicle's onboard elec-
tronic systems.<
Charging the batteryWhen charging the battery in the
vehicle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment. For
terminal locations, refer to Jump-
starting on page 128.
Return used batteries to a recycling
point or your BMW center. Maintain
the battery in an upright position for
transport and storage. Secure the
battery against falling over in transit.<
The fuses are located in the glove
compartment behind a cover secured
by two snap clips.
Do not attempt to repair a blown
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<
