Replacing components

3. Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4. Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5. Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1. Tighten the lug bolts in a diagonal pattern.
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 speci-
fied torque. Otherwise, incorrectly tight-
ened lug bolts are a hidden safety risk. The
tightening torque is 101 lb ft/140 Nm.

2. Stow the defective wheel in the cargo area.
The defective wheel cannot be stored
under the floor panel flap due to its
size. <
3. Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve screw
caps against dirt and contamination.
Dirt in valve stems is a frequent source of
gradual air loss.

4. Initialize the Flat Tire Monitor, refer to
page
100 , or reset the Tire Pressure Moni-
tor, refer to page 102 .
5. Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Otherwise,
changes in the driving characteristics could
result, for example reduced track stability on
braking, extended braking distance, and altered
self-steering characteristics in the limit range.
In conjunction with winter tires, these charac-
teristics are more pronounced.
<
Only one compact wheel may be
mounted. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk.

Vehicle battery
Battery care
The battery is 100% maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be glad to advise in all matters concerning
the battery.
Replacing battery
Only use vehicle batteries that have been
approved for your vehicle by the manu-
facturer; otherwise, the vehicle could be dam-
aged and systems or functions may not be fully
available.
<
After a battery replacement, have the battery
registered on the vehicle by your BMW Sports
Activity Vehicle Center to ensure that all com-
fort functions are fully available.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. Connections, refer to
Jump starting on page
274 .
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a recycling cen-
ter. Maintain the battery in an upright position
for transport and storage. Always restrain the
battery to prevent it from tipping over during
transport.

Power failure
Following a temporary power failure, e.g. due to
a discharged battery, the use of some equip-
ment will be restricted, requiring its reinitializa-
