5.

Replace the damaged tire with a new one as
soon as possible and have the new wheel
balanced.

Driving with compact wheel

Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Do not deacti-

vate DSC, as otherwise unstable driving condi-
tions may result.

<

The driving characteristics change, 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 characteristics are more
pronounced.

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

wheels and tires of the original size as quickly 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 consult you on all questions
concerning the battery.

Warning lamp

The warning lamp lights up. The bat-
tery is no longer being charged. The
alternator V-belt is defective or there is

a malfunction 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 is not running. Use the connections pro-
vided in the engine compartment. For connec-
tions, refer to Jump starting on page

104

.

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.
