level must be between the "MIN" and
"MAX" markings .
The brake f luid reservoir is located at the rear
partition of the engine compartment on the

page 239 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .

-Always wear eye protection. Do not let
battery acid or any lead particles get on
your skin or clothing. Shield your eyes .
Explosive gases can cause blindness or
other injury.
- Battery acid contains sulfuric acid . Sulfu­
ric acid can cause blindness and severe
burns.
- Always wear gloves and eye protection.
Do not tilt the battery because acid
could leak out of the ventilation open­
ings.
- If you get battery acid in your eyes or
on your skin, immediately rinse with
cold water for several minutes and get
medical attention .
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables .
= When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury .
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca­ ble .
- Before performing any work on the elec­
trical system, switch off the engine and
ignition as well as any electrical equip ­
ment. The negative cable on the battery
must be disconnected . If you are just go­

and then the negative cable . Never inter ­
change the cables -this could start a fire!
- Never charge a frozen or a thawed-out
battery . It could explode! If a battery has
frozen , then it must be replaced . A dis­
charged battery can freeze over at 32°F
(QOC),
-Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery .
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery.

erwise it will be damaged and will then
have to be replaced.
