which is hazardous. The AIC system should be serviced only by
trained technicians using approved refrigerant recoverylrecycling
equipment, trained in related safety precautions, and familiar with
regulations governing the discharging and disposal of automotive
chemical refrigerants.
. Do not expose any part of the AIC system to high temperatures
such as open flame. Excessive heat will increase system pres-
sure and may cause the system to burst.
Some aerosol tire inflators are highly flammable. Be extremely
cautious when repairing a tire that may have been inflated using
an aerosol tire inflator. Keep sparks, open flame or other sources
of ignition away
from the tire repair area. Inflate and deflate the

CAUTIONS-
See also WARNINGS
- if you lack the slqills, tools and equipment, or a suitable worl(shop
for any procedure described in this manual, leave such repairs to
an authorized BMW dealer or other qualified shop.
BMW is constantly improving its cars and sometimes these
changes, both in parts and specifications, are made applicable to
earlier models. Therefore, part numbers listed in this manual are
for reference only. Always check with your authorized BMW deal-
er parts department for the latest information.
Before starting a job, make certain that you have all the neces-
sary tools and parts on hand. Read ail the instructions thorough-
ly, and do not attempt shortcuts. Use tools appropriate to the
work and use only replacement parts meeting BMW specifica-
tions.
Use pneumatic and electric tools only to loosen threaded parts
and fasteners. Never use these tools to tighten fasteners, espe-
cially on light alloy parts. Always use a torque wrench to tighten
fasteners to the tightening torque specification listed.
Be mindful of the environment and ecology. Before you drain the
crankcase, find out the proper way to dispose of the
oil. Do not
pour
oil onto the ground, down a drain, or into a stream, pond or
lake. Dispose of waste in accordance with Federal, State and
Local laws.
The control module for the anti-lock brake system
(ABS) cannot
withstand temperatures from a paint-drying booth or a heat
lamp
in excess of 203" F (95°C) and should not be subjected to tem-
peratures in excess of 185°F
(8S°C) for more than two hours.
- Before doing any electrical welding on cars equipped with ABS,
disconnect the battery negative
(-) terminal (ground strap) and
the ABS control module connector.
- Always make sure ignition is off before disconnecting battery.
Label battery cables before disconnecting. On some models, bat-
tery cables are not color coded.

by an illuminated warning light), see an authorized BMW dealer.
If a normal
or rapid charger is used to charge battery, the battery
must be disconnected and removed from the vehicle in order to
avoid damaging the vehicle.
- Do not quick-charge the battery (for boost starting) for longer
than one minute. Wait at least one minute before boosting the
battery a second time.
* Connect and disconnect a battery charger only with the battery
charger switched off.
- Sealed or "maintenance free" batteries should be slow-charged
only, at an amperage rate that is approximately 10% of the bat-
tery's ampere-hour (Ah)
rating.
. Do not allow battery charging voltage to exceed 16.5 volts. If the
battery begins producing gas or boiling violently, reduce the
charging rate.
Boosting a sulfated battery at a high charging rate
can cause an explosion.

General
Electrical testing
Many electrical problems can be understood and solved with
only a little fundamental knowledge of how electrical circuits
function.
Electrical current
only flows in a complete circuit. To operate.
every electrical device in the car requires a complete circuit
including a voltage source and a path to ground. The positive
(+) side of the battery is the original voltage source, and
ground is any return path to the negative
(-) side of the bat-
tery, whether through the wiring harness or the car body. Ex-
cept for portions of the charging system, all electrical current
in the car is direct current (DC) and flows from positive
(+) to
negative
(-).
4 Switches are used to turn components on or off by complet-
ing or interrupting the circuit.
A switch is "open" when the cir-
cuit is interrupted, and "closed" when the circuit is completed.

600 Electrical System-General for electrical trouble-

repair permanent. The wire ends must be clean.
if frayed or
Car body otherwise damaged, cut off the end and remove enough insu- (ground) i Battery lation to complete the repair. if the wire is too short, splice in a BOZLiEL new piece of wire of the same size and make two connec-
tions.
Use connectors that are designed for the purpose. Crimped
on orsoldered-on connectors are best. Crimp connectors and
special crimping pliers are widely available. If soldering, use
needle nose pliers to hold the wire near the solder joint and
create a "heat dam". This keeps the heat and the solder from
traveling up the wire. Always use a solder made specifically
for electrical
work (rosin core).
NOJE-
Twisting wires together to make a repair is not recommend-
ed. Corrosion and vibration will eventually spoil the connec-
tion and may lead to irreparable damage to sensitive
electronic components.
Insulate the finished connection. Electronics stores can sup-
ply heat-shrinkable insulating tubing that can be placed on to
the wire before connecting, slid over the finished joint, and
shrunic to a tight fit with a heat gun or hair dryer. The next best
alternative is electrical tape. Make sure the wire is clean and
free of
solder flux or other contamination. Wrap the joint tight-
ly to seal out moisture. See
600 Electrical System-General
for more information.

General
BMW special tools
Many repairs covered in this manual call for the use of BMW
special tools. Many of the BMW special tools mentioned in
this manual are simply the best thing to use to do the job cor-
rectly. In these cases, the tool is identified with a
BMW parl
number. See your authorized BMW dealer parts department
for information on how to order special tools.
There are some jobs for which expensive special tools are es-
sential, and not a cost-effective purchase for a one time repair
by the do-it-yourself owner. This manual includes such re-
pairs for the benefit of those with the necessary experience
and access to tools. For the do-it-yourselfer, the need for spe-
cial tools is noted in the text, and whether or not BMW dealer
service is recommended.
Changing a tire
- Stop car on as flat a surface as possible, in a place where you
can be easily seen by other drivers. Avoid stopping just over
the crest of a hill.
WARNING -
If a tire goes flat while driving, pull well off the road. Changing
a tire on a busy slreet or liigliway is very dangerous. If
nec-
essag drive a short distance on the flat tire to get to a safe
place. It is much better to ruin a tire or rim than to
risk being
hit.
-
- Turn on emergency flashers, and set out flares or emergency
markers well behind car.
Choclc wheel (wheel chock located
in trunk) diagonally opposite to the one being changed. Pas-
sengers should get out of car and stand well away from road.
- Take jaclc and tools from tool area beneath trunk mat. Re-
move spare tire from tire storage tray.
- Loosen wheel bolts while car is on ground, but leave them a
little snug.
< Place jack in lifting point nearest wheel being changed. Use
a board to provide a firm footing for jack if ground is soft.
Raise car only far enough so that the wheel is fully off ground
and then remove wheel nuts and wheel.
- Install spare wheel. Install wheel nuts and tighten them hand
tight using lug nut wrench.

Indicator and warning lights
Many vehicle systems are self-monitored for faults while driv-
ing. Generally,
a red warning lamp that comes on during driv-
ing should be considered serious. If you cannot immediately
determine the seriousness of the warning light, stop the vehi-
cle in a safe place and turn the engine off as soon as possible.
Consult the owner's manual for additional information on the
warning lamp and the recommended action.
If the Malfunction Indicator Lamp (MIL)
(Check Engine or Ser-
vice Engine Soon warning light) comes on orflashes, it indi-
cates that an emissions-related fault has occurred. Faults
such as a bad oxygen sensor or a dead fuel injector can
cause the exhaust or evaporative emissions to exceed a
specified limit. When these limits are exceeded, the MIL will
be turned on. The engine can be safety driven with the light
on, although the emission systems should be
checked as
soon as possible. See OBD On-Board Diagnostics for

(6-cylinder oil cap shown, V-8 is sirnilar).
- Add only amount needed to bring oil level to upper mark on
dipstick, using an oil of correct viscosity and grade.
Engine oil and filter, changing
A complete oil change requires new oil, a new filter insert kit,
and a new drain plug sealing washer. The tools needed, a
17
mm drain plug socket or box wrench, a 36 mm socket or
wrench, and a drain pan (8
- 10 US qt. capacity), are de-
scribed in
010 General.
NOTE-
If using a "fast 1ube"service facility for oil changes, make sure
the technician hand-starts and torques the engine oil drain
plug using hand-tools. Power tools can strip the threads of
the plug and the oil pan.
Run engine for afew minutes to warm engine oil. Shut engine
off.
With car on level ground, place drain pan under oil drain plug.
Using a
36 mm socket, loosen and remove oil filter housing
