Vehicle Battery; Battery Care; Charging Battery - BMW 525i Owner's Manual

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. The tightening torque is
88.5 lb ft/120 Nm.<
2. When stowing the wheel and tools in the
vehicle, execute these steps in the reverse
order.
3. 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.<
4. Reinitialize the Flat Tire Monitor, refer to
page 87.
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.
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

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 center will be glad to advise in
all matters concerning the battery.

Charging battery

Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump starting
on page 209.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling center. 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
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings are also lost
and must be updated again:
> Active steering
The system is deactivated and must be ini-
tialized, refer to page 89. Until then, the
steering will react differently than in the
accustomed manner.
> Seat, mirror and steering wheel memory
The positions must be stored again, refer to
page 44.
> Time and Date
The settings must be updated, refer to
page 80.
> Radio
The stations must be stored again if neces-
sary, refer to page 152.
>
Navigation system
You must wait until it becomes operational
again, refer to page 140.
