Chrysler 2005 PT Cruiser Convertible - Manual (Page 242)

WARNING!
Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or clothing.
Don’t lean over battery when attaching clamps or
allow the clamps to touch each other. If acid splashes
in eyes or on skin, flush the contaminated area
immediately with large quantities of water.
A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away
from the vent holes. Do not use a booster battery or
any other booster source with an output that exceeds
12 volts.
5. Connect the other cable, first to the negative terminal
of the booster battery and then to the negative jump start
terminal, located near the hood release latch, of the
vehicle with the discharged battery. Make sure you have
a good contact.
6. Turn the ignition switch to the ON position for 3
seconds before moving the ignition switch to the START
position.
7. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.
