between 8-11 (undercharge) or above 15 (overcharge)
indicate possible malfunction of generator, voltage
regulator or battery. See your dealer if such indications

WARNING!
²Do not connect the cable to the negative terminal
of the discharged battery. The resulting electrical
spark could cause the battery to explode.
²During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting to jump start.
3. Take care that the clamps from one cable do not touch
clamps from the other cable. Do not lean over the battery
when making the connection. The negative connection
must provide good electrical conductivity and current
carrying capacity.4. After the engine is started or if the engine fails to start,
the cables must be disconnected in the following order:
a. Disconnect the negative cable at the engine
ground.
b. Disconnect the negative cable at the negative
terminal on the booster battery.
c. Disconnect the cable from the positive terminals
of both batteries.
WARNING!
Any procedure other than above could result in:
²Personal injury caused by electrolyte squirting
out the battery vent.
²Personal injury or property damage due to battery
explosion.
²Damage to charging system of booster vehicle or
of immobilized vehicle.
