To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Maintenance Free Battery
The top of the maintenance free battery is permanently
sealed. You will never have to add water, nor is periodic
maintenance required.
WARNING!
²Battery fluid is a corrosive acid solution and can
burn or even blind you. Don't allow battery fluid
to contact your eyes, skin or clothing. Don't lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water.
²Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Don't use a
booster battery or any other booster source with an
output greater than 12 volts. Don't allow cable
clamps to touch each other.
²Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands
after handling.
