Batteries
giveoff explosive hydrogen gas during charging. Keep
sparks, lighted matches and open flame away from the top of the
battery. If hydrogen gas escaping from the cap vents is ignited, it
will ignite gas trapped in the cells and cause the battery to ex-

General
WARNING-
Never run the engine in tile work area unless it is well-ven-
tilated. The exhaust should be vented to the outside. Car-
bon monoxide (CO) in exhaust kills.
Remove all neckties,
scarfs, loose clothing, or jewelry
when working near a running engine or power tools.
Tuck in shirts. Tie long hair and secure it under a cap.
Severe injury can result from these things being
caugiit
in rotating parts.
Remove rings, watches, and bracelets. Aside from the
dangers of moving parts, metallic jewelry conducts
electricity and may cause shorts, sparks, burns, or
damage to the electricalsystem when accidentally con-
tacting the battery or other electrical terminals.
Disconnect the battery negative
(-) cable whenever
working on or near the fuel system or anything that is
electrically powered. Accidental electrical contact may
damage the electrical system or cause a fire.
Fuelis highly flammable. When working around fuel, do
not
smoke or work near heaters or other fire hazards.
Keep an approved fire extinguisher handy.
The fuel system is designed to retain pressure even
when the ignition is off When worlcing with the
fuelsys-
tem, loosen the fuel lines slowly to allow the residual
pressure to dissipate gradually. Take precautions to
avoid spraying fuel.
. Illuminate the worlc area adequately and safely Use a
portable safety light for worlcing inside or under the car.
A fluorescent type
light is best because it gives off less
heat. If using a light with a normal incandescent bulb,
use rough service bulbs to avoid
breakage. The hot fil-
ament of an accidentally broken bulb can ignite spilled
fuel or oil.
Keep sparks, lighted matches, and any open flame
away from the top of the battery. Hydrogen gas
emitted
by the battery is highly flammable. Any nearby source
of ignition may cause the battery to explode.
Never lay
tools or parts in the engine compartment or
on top of the battery. They may
fallinto confinedspaces
and be difficult to retrieve, become caught in belts or
other rotating parts when the engine is started, or
cause electrical shorts and damage to the electrical
system.

With the introduction of synthetic oil and extended oil change
intervals, a new oil filterwith improved filter paper design was
introduced. The new filter paper resists deterioration caused
by high oil temperatures over an extended time.
Specification
Use BMW specified oil to top off the engine oil level between
oil changes.

Maintenance
Drive axle joint
(CV joint) boots, inspecting
CVjoint protective boots must be closely inspected forcracks
and any other damage that will allow contaminants to get into
the joint.
If the rubber boots fail, the water and dirt that enter
the joint will quickly damage it.
NOTE-
Replacement of the CVjoint boots and inspection of the
joints are described
in 331 Final Drive.
Exhaust system, inspecting
Exhaust system life varies widely according to driving habits
and environmental conditions. If short-distance driving pre-
dominates, the moisture and condensation in the system will
not fully dry out. This will lead to early corrosion damage and
more frequent replacement.
Scheduled maintenance of the exhaust system is limited to
inspection:
* Check to see that all the hangers (arrow) are in place and
properly supporting the system and that the system does
not strike the body.
Check for restrictions due to dents or
kinlts,
Check for weakness or perforation due to rust.
NOTE-
Alignment of the system and the location of the hangers are
described in
180 Exhaust System.
Fuel filter, replacing
The fuel filter is located beneath the center of the car, approx-
imately under the driver's seat.
A protective cover must be
removed to access the filter.
4 Fuel filter for M62 engine (arrow)
- Disconnect battery negative (-) cable
CAUTIOI\C
Disconnecting the battery cables may erase fault codes
stored
in engine control module memory.
WARNING -
Fuel will be expelled forcibly when the filter is removed. Do
notsmoke or work near heaters orother fire hazards. Keep a
fire extinguisher handy
