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 watch bands or bracelets that might make an
inadvertent electrical contact. You could be seriously injured.

hydrogen gas which is flammable and explosive. Keep open flames or sparks
away from the battery.
• Set the parking brake, shift the automatic transmission into PARK and turn the ignition to
LOCK.
