Replacing parts

3. Fit the new wheel or the compact wheel and
insert at least two diagonally opposed
wheel studs.
If the car is not fitted with alloy wheels of the
Genuine BMW type, note that different
wheel studs may be needed.
4. Insert and screw up the remaining wheel
studs, then tighten them all firmly, working
across the hub rather than round it.
5. Lower the car and remove the jack.
After fitting
1. Tighten the studs alternately on opposite
sides of the hub.
For safety reasons, have the wheel
stud tightening torque checked with-
out delay, using a calibrated torque wrench.
The correct tightening torque is 120 Nm,
approx. 89 lb ft.<
2. Proceed in the reverse sequence when
storing the wheel and tools.
3. Correct the tyre pressure at the earliest
opportunity.
Prevent dirt entering the tyre valves
by attaching screw-on dust caps. Dirt
in the tyre valve can often lead to a gradual
loss of air pressure.<
4. Initialise the Run Flat Indicator, see
page 87.
5. Renew the damaged tyre as soon as possi-
ble and have the new wheel balanced.
Driving with the compact wheel fitted
Drive with caution and do not exceed 80 km/h,
approx. 50 mph.
The car's handling properties, such as track
stability during braking, braking distances and
the self-steering properties at the limits of han-
dling, may have changed. These effects will be
more pronounced in combination with winter
tyres.
Only one compact wheel may be fitted at
one time. Fit a wheel/tyre combination
that matches that of the remaining wheels/tyres
at the earliest possible opportunity.<

Car battery
Maintenance
The battery needs no routine maintenance
whatsoever, in other words the quantity of acid
it contains will normally last for the full operating
life of the battery in temperate climates. BMW
Service will gladly advise you on all matters
relating to batteries.
Recharging the battery
Recharge the battery only with the engine
stopped, via the connections in the engine
compartment. Connections, see Starting with a
flat battery on page 201.
