WARNING!
• 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.
1. Apply the parking brake, shift the automatic transmis-
sion into PARK (P) (manual transmission in NEUTRAL)
and turn the ignition OFF.
2. Turn off the heater, radio, and all unnecessary electrical
