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 transmission into PARK and
turn the ignition OFF.
2. Turn off the heater, radio, and all
unnecessary electrical accessories.
3. If using another vehicle to jump start the
battery, park the vehicle within the jumper
cables' reach, apply the parking brake and
make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
