Replacing components

114

Protect valve stems with valve stem
seal caps from dirt and contamina-

tion. Dirt in valve stems is a frequent source
of gradual air loss.

Reinitialize the Flat Tire Monitor

or reset

the Tire Pressure Monitor

, refer to

pages

Do not initialize the Flat Tire Monitor
when driving with a compact wheel.

Replace the defective 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.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.

Only one compact wheel may be
mounted. You should re-equip with

wheels and tires of the original size as soon as
possible.

Vehicle battery

Maintenance

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 happy to advise you on all questions con-
cerning the battery.

Warning lamp

The warning lamp lights up. The battery
is no longer being charged. The alterna-
tor V-belt is defective or there is a mal-

function in the charge current circuit of the
alternator. Have the system checked immedi-
ately.

Do not continue driving if the V-belt is
defective. The engine could be damaged

due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.

Charging battery

Charge the battery in the vehicle only when the
engine has been switched off. For connections,
refer to Jump starting on page

Disposal

Have old batteries disposed of following
replacement at your BMW Sports Activity

Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.
