2005 BMW 525I ECU

Replacing components
186 With run-flat tires, no tools are provided
for wheel changes. They can be pur-
chased as accessories at your BMW center.<
Compact wheel*
1.Unscrew the wing nut 1.
2.Remove the washer 2 laterally.
3.Take out the tool mounts 3.
4.Remove the compact wheel.
Preparing wheel change
1.Observe the safety precautions above.
2.Prevent the vehicle from rolling:
Place the chock behind the front wheel on
the other side of the vehicle, or on inclines,
in front of this wheel. On a steep grade, take
other steps to prevent the vehicle from roll-
ing.
3.Loosen the lug bolts a half turn.
Jacking up vehicle
1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base rests on the ground
perpendicularly beneath the jacking point.
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.<2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a 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. Also 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.
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.

Giving and receiving assistance
192
Vehicles with manual transmission
Gearshift lever in neutral position.
Vehicles with automatic transmission
Selector lever in position N.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km, as otherwise the automatic
transmission may be damaged.<
Vehicles with SMG Sequential manual
transmission
With the ignition switched on, engage the
selector lever position N, then switch off the

Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as otherwise
it will not be possible to control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Secure the tow bar to the tow fitting only.
Otherwise damage to other vehicle parts
could result.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Secure the tow rope to the tow fitting only.
Otherwise damage to other vehicle parts could
result.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a load bed.
Do not lift vehicle by tow fitting or body
and chassis parts, as otherwise damage
may result.<
Tow-starting
Do not tow-start vehicles with an auto-
matic transmission.
Jump starting, refer to page190.<
Only tow-start vehicles with a catalytic con-
verter with the engine cold. It is better to jump
start the engine, refer to page190.
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
2.Turn the ignition key to position 2.
3.Shift into 3rd gear. Vehicles with SMG, see
below.
4.Have the vehicle tow-started with the clutch
pedal completely depressed and slowly
release the clutch. After the engine starts,
immediately depress the clutch pedal com-
pletely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
