Changing a wheel
Take these precautionary
measures if you have either a flat
tire or are changing the tire:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat
surface. Switch on the hazard flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse (selector lever in "Park" with
automatic) and engage the parking
brake.
Have all passengers leave the vehicle
and remain well away from your imme-
diate working area (behind a guardrail,
for instance).
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all applicable safety guidelines and
regulations.
Change the wheel only on a level, firm
surface that is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface (snow, ice, loose
gravel, etc.), as it could slide sideways.
Position the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack. If you do so, the
jack might not be able to reach its full
support capacity because of the limited
height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack. Failure to comply with this
creates a risk of fatal injury.<
Your BMW has either a spare wheel or
a space-saver spare tire for temporary
use and to ensure your mobility.
To remove the spare wheel, lift out
the floor panel in the luggage
compartment completely (refer to
page 41).<
You will need the followingIn order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Jack (1)
Raise the floor panel in the luggage
compartment (refer to page 41) and
loosen the red wing nut (arrow).
When you have completed work,
screw the jack all the way back
down. Fold the handle back and
insert it in its holder

Changing a wheel9 Position the new wheel or the
space-saver spare tire on the hub
and screw at least two lug bolts
finger-tight into opposite bolt holes
10 Screw in the remaining lug bolts.
Tighten all the bolts securely
11 Lower the jack and remove it from
beneath the vehicle
12 Tighten the lug bolts in a diagonal
pattern462de267
13 Wheels with full wheel covers
*:
Position the wheel cover with the
valve opening over the valve (arrow)
and press it onto the wheel with
both hands
14 Check and correct the tire's inflation
pressure at the earliest possibility.
For vehicles with RDC (Tire Pres-
sure Control):
Reactivate the system after
mounting the spare wheel or
correcting the inflation pressure.
Refer to page 86.
Use original BMW full wheel
covers only. Other wheel covers
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire, since this could
damage the cover.<
460de125
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.
Have the lug bolts checked for proper
tightness with a calibrated torque
wrench at the earliest possibility [torque
specification: 72 lb.ft. (100 Nm)].<
When storing the wheel, be sure 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 quickly as
possible and have the new wheel
balanced.

BatteryBattery careThe battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.
For all questions that regard the
battery, please consult your BMW
center. Since the battery is mainte-
nance-free, the following is for your
information only.
please comply with the corresponding
precautions whenever you work with or
near the battery.
Before handling the battery,
please read the following infor-
mation.
Wear eye protection. Do not
allow particles containing
battery acid or lead to come into
contact with your eyes, your skin, or
your clothing.
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Do not allow children access to
batteries and battery acid.
Never allow sparks or open
flame in the vicinity of the
battery. Avoid sparks from elec-
trical cables or electrical equipment.
Turn the key to position 0 in the
steering lock when disconnecting or
connecting the battery. Do not short-
circuit the battery terminals. This
creates a risk of injury from high-energy
sparks.
A highly explosive gas is gener-
ated when the battery is charged.
If battery acid is splashed into
your eyes, immediately rinse
them with clear water for
15 minutes. Consult a physician imme-
diately. If your skin or clothing are
splashed by acid, rinse immediately
with ample clear water. If battery acid is
accidentally swallowed, consult a
physician immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.
Removal 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 elec-
tronics.
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. If this
is not done, the battery will not be
adequately secured in case of an acci-
dent.<

ratings and the equipment in their
circuits are all indicated below the fuse
holder.
To close the fuse holder, snap it into
position at the top and turn the two
fasteners inward.
Do not attempt to repair a burned
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<
If a fuse blows repeatedly, refer the
problem to your BMW center for repair.

Do not use spray starter fluids.
If the battery is discharged, the engine
can be started with the use of two
jumper cables and the battery of
another vehicle. Use only jumper cables
with fully insulated grips on the terminal
clamps.
Do not touch the parts conducting
electrical current while the engine
is running. Failure to comply with this
creates a risk of fatal injury.<
Carefully comply with the following
instructions to avoid personal injury or
damage to one or both vehicles:
1 Be sure that the battery on the
support vehicle is also rated at
12 volts, and that the capacities of
the two batteries (Ah) are roughly
comparable (printed on casing)
2 Leave the discharged battery
connected to the vehicle's electrical
system
3 Make sure that there is no contact
between the bodywork of the two
vehicles Ð this creates a risk of short
circuits
4 Start by connecting the jumper cable
from the positive terminal of the
support vehicle to the positive
terminal connector located in your
BMW's engine compartment. The
cover of the positive terminal
connector is marked with a "+" sign.
Refer to the illustration. Remove by
pulling the tab (arrow 1)
5 Then connect the negative terminals.
Attach the cable to either the support
vehicle's negative battery terminal (Ð),
or to a suitable ground on its engine
or bodywork. Then connect the other
end of the cable to a ground on the
engine or on the bodywork of the
vehicle that is to be started. There is
a special nut provided for this on the
BMW (arrow 2)462us053
Follow the same sequence for
connecting the jumper cables
when helping other vehicles. If you do
not, there is the risk of injury if sparks
are generated at the battery.<
6 Start the engine of the support
vehicle and let it run
7 Start the engine on the vehicle
needing the jump-start, and allow it
to run as usual. If the first start
attempt is not successful, wait a few
minutes before another attempt in
order to allow the discharged battery
to recharge
8 Before disconnecting the jumper
cables from your BMW, turn on the
lighting, the rear window defroster
and set the blower to the highest
speed; allow the engine to run
approx. 10 seconds. This will prevent
a voltage surge from the voltage
regulator to the electrical accessories
9 Then disconnect the jumper cables in
reverse sequence.
Depending on the cause of the fault,
recharge the battery.
