Procedure1 Read and comply with the safety
precautions provided on the previ-
ous page
2 Secure the vehicle against rolling:
Place the wedge against the rear
surface of the front tire on the side
opposite the side being raised. If
the vehicle is parked on a down-
ward slope, place the wedge se-
curely in front of the tire. If the
wheel must be changed on a sur-
face with a more severe slope, take
additional precautions to secure the
vehicle against rolling
3 If your wheels are equipped with full
wheel covers
*, reach into the venti-
lation openings and pull the cover
off

4 Loosen the lug bolts 1/2 turn
5 Position the jack at the jacking point
closest to the flat tire (refer to the
center illustration) so that the jack
base is vertically below the jacking
point and the entire surface of the
head of the jack will move into the
square recess of the jacking point
(refer to the illustration detail) when
the jack is cranked
6 Jack the vehicle up until the wheel
you are changing is raised from the
ground
7 Unscrew the lug bolts and remove
the wheel

Changing a wheel9 Position the new wheel or the
space-saver spare tire on the hub
and screw at least two lug bolts fin-
ger-tight into opposite bolt holes
10 Screw in the remaining lug bolts.
Tighten all the bolts snugly
11 Lower the jack and remove it from
beneath the vehicle
12 Tighten the lug bolts in a diagonal
pattern462de266
13 If your wheels are equipped with full
wheel covers
*, place the wheel
cover with the valve opening over
the valve (arrow). Use both hands to
press the cover securely onto the
rim
14 Check and correct the tire's inflation
pressure at the earliest possibility.
For vehicles with RDC (Tire Pres-
sure Control)*:
After mounting the space-saver
spare tire or correcting the inflation
pressure, reactivate the system.
Refer to page 89.
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire, since this could
damage the cover.<
462de279
The vehicle jack is designed for
changing wheels only. Do not at-
tempt 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 continued safety, have the
solid fit of the lug bolts [torque: 72 lbft
(100 Nm)] checked using a calibrated
torque wrench.<
When storing the wheel, take care to
ensure that you do not damage the
retaining pin in the spare tire recess.
If light-alloy wheels other than original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.

BatteryRemoval and installation
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.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repair and disposal must be performed
by trained technicians only.<
When removing the battery, disconnect
the cable on the negative terminal first,
then the cable on the positive terminal.
Loosen the center adjusting screw on
the battery retaining strap (use the
screwdriver included with the onboard
tool kit) and disconnect the strap.
When installing a battery, connect the
positive terminal first, then connect the
negative terminal.
When installing a battery, be sure
that it is mounted properly and that
the retaining bracket is installed with the
center adjustment screw, otherwise, the
battery will not be adequately secured
in case of an accident.<
Charging the battery Charge the battery in the vehicle only
when the engine is not running.
Before performing any work on
the electrical system, be sure to
unclamp the cable from the battery's
negative terminal. Failure to do so can
result in short-circuits, a fire or per-
sonal injury.<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle's electrical system by
disconnecting the cable at the negative
terminal. Then recharge the battery with
an appropriate battery charger.
If you intend to store the vehicle for
longer than 12 weeks, remove the bat-
tery, charge it and store it in a cool and
dust-free room where there is no dan-
ger of freezing. During storage, have
the battery recharged every 3 months.
Also, recharge the battery before it is
reinstalled. If this is not done, the bat-
tery will not be serviceable. Every time
the battery is drained, especially over
extended periods, its service life is
reduced.
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery to prevent it from tilting
during transport.<
Storage periods during which
the battery is disconnected are
not taken into consideration by the
Service Interval Display for changing
the brake fluid.
For this reason, be sure that the brake
fluid is changed every two years, re-
gardless of the information displayed.
Read and comply with the information
on page 136 covering this subject.<
