Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can be
injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could make
an inadvertent electrical contact. You could be
seriously injured.
Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen gas
which is flammable and explosive. Keep open
flames or sparks away from the battery.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster
vehicle or the discharged vehicle.

Do not attempt to inspect an accessory drive
belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. You could be
injured by the moving fan blades.
You can be badly injured working on or around
a motor vehicle. Only do service work for which
you have the knowledge and the proper equip-
ment. If you have any doubt about your ability
to perform a service job, take your vehicle to a
competent mechanic.
WARNING!
Use only refrigerants and compressor lubri -
cants approved by the manufacturer for your air

erants are flammable and can explode, injuring
you. Other unapproved refrigerants or lubri -
cants can cause the system to fail, requiring
costly repairs. Refer to Warranty Information
Book, located in your owner’s information kit,
for further warranty information.

Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.

12 Volt electrical system.
Serious injury or death could result if you do
not disconnect both batteries. To learn how to
properly disconnect, see an authorized dealer.
CAUTION!
If the negative battery cables are not isolated
properly it can cause a potential power spike or
surge in the system, resulting in damage to
essential electrical components.
