ECU BMW 525I 2004 Owner's Manual

Replacing components
188 3.Loosen the lug bolts 1/2 a turn
4.Set up the jack beneath the jacking
point closest to the flat tire. Ensure that
the entire surface of the jack's base is in
firm contact with the ground and that
the jack itself is standing completely
vertical, not tilted, and that the fitting on
the top of the jack will align with the
rectangular recess on the vehicle when
you raise it, refer to illustration
5.Jack the vehicle up until the wheel you
are changing is raised from the ground
6.Unscrew the lug bolts and remove the
wheel
7.Remove accumulations of mud or dirt
from the mounting surfaces of the
wheel and hub. Clean the lug bolts
8.Position the new wheel or compact
wheel. Secure the wheel by turning at
least two lug bolts into opposite bolt
holes
9.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
10.Lower the jack and remove it from
beneath the vehicle
11.Tighten the lug bolts in a diagonal pat-
tern
12.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 wheel or correcting the
inflation pressure, reinitialize the Flat Tire
Monitor, refer to page 81.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
as soon as possible to ensure that they are
tightened to the specified torque.
The tightening torque is 120 Nm.<
Reverse the removal sequence to store the
wheel and tools in the vehicle.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
Always have damaged tires replaced and
the wheel and tire assembly rebalanced at
the earliest possible opportunity.
Driving with the 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 pro-
nounced.
Only one compact wheel may be
mounted. You should fit wheels and
tires of the original size as quickly as possi-
ble.<
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.
For all questions that regard the bat-
tery, please consult your BMW cen-
ter.<
