300 WHAT TO DO IN EMERGENCIES
NOTE: To start the vehicle following connection of a
booster battery, the Security Alarm System must first be
disabled by cycling a front door key cylinder or by using
the keyless entry transmitter.
WARNING!
Jump starting can be dangerous. To avoid personal
injury or damage to electrical components in vehicle,
observe the following warnings:
• Battery 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 immediately with large amounts of
water.
• Do not use a booster battery or any other booster
source that has a greater than 12–volt system, i.e., do
not use a 24–volt power source.
• Never attempt to jump start a discharged battery that
is frozen, because it could rupture or explode during
jump starting.
• Be sure your vehicle is not touching the jump start
vehicle.
• Observe all Battery Warnings in Section 7 of this
manual, while jump starting your vehicle.
