Mounting compact wheel
1.
Unscrew the lug bolts and remove the
wheel
2.
Remove accumulations of mud or dirt
from the mounting surfaces of the
wheel and hub. Clean the lug bolts
3.
Position the new wheel or compact
wheel. Secure the wheel by turning at
least two lug bolts into opposite bolt
holes
4.
Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
5.
Lower the jack and remove it from
beneath the vehicle
6.
Tighten the lug bolts in a diagonal pat-
tern
7.
Check and correct the tire inflation
pressure at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.
<
After mounting the compact wheel or cor-
recting the inflation pressure, reinitialize
the Flat Tire Monitor, refer to page
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 safety, always have the lug bolts
checked with a calibrated torque wrench to
ensure that they are tightened to the spec-
ified torque of 101 lb ft/140 Nm as soon as
possible.
<
Stow the defective wheel in the luggage
compartment.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
Replace the defective tire as soon as pos-
sible and have the new wheel/tire bal-
anced.
Driving with the compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Do not
deactivate DSC, as otherwise unstable
driving conditions 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 pro-
nounced.
Only one compact wheel may be
mounted. You should re-equipping to
wheels and tires of the original size as
quickly as possible.

Battery
Battery care
The battery is 100 % maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate.
Please contact your BMW Sports
Activity Vehicle Center with any ques-
tions concerning the battery.
<
Do not disconnect the battery when
the engine is running. If you do so, the
ensuing voltage surge will damage the
vehicle's onboard electronics.
<
Indicator lamp
The battery charge-current indica-
tor lamp lights up:
The battery is no longer being
charged. There is a defect on the alternator
V-belt or charge current circuit of the alter-
nator. Contact the nearest BMW Sports
Activity Vehicle Center.
Do not continue driving if the V-belt is
defective. The engine could be dam-
aged due to overheating.
Moreover, an increased amount of force is
required for steering if the onboard supply
voltage falls dramatically.
