WHAT TO DO IN EMERGENCIES
• 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 hurt by the fan.
• Remove any metal jewelry, such as watch bands or bracelets, that might make an
inadvertent electrical contact. You could be seriously injured.
• Battery fluid is a corrosive acid solution; do not allow battery fluid to contact eyes,
skin or clothing. Do not lean over a battery when attaching clamps or allow the
clamps to touch each other. If acid splashes in your eyes or on skin, flush the
contaminated area immediately with large quantities of water.
• A battery generates hydrogen gas which is flammable and explosive. Keep flames
or sparks away from the battery vent holes. Don't lean over the battery when
attaching clamps or allow the clamps to touch each other.
• Do not use a booster battery or any other booster source with an output that
exceeds 12-volts (i.e., do not use a 24-volt power source).
• Check the battery test indicator (if equipped). If a light or bright colored dot is visible in
the indicator, DO NOT jump-start the battery. If the indicator is dark or shows a green dot,
proceed as follows:
• Remove all metal jewelry, such as watch bands or bracelets, which might make an
unintended electrical contact.
• Do not permit vehicles to touch each other as this could establish a ground
connection and personal injury could result.
• Do not connect the cable to the negative post of the discharged battery. The
resulting electrical spark could cause the battery to explode and could result in
personal injury.
• Park the booster vehicle within cable reach but without letting the vehicles touch. Set the
parking brake on both vehicles, shift the automatic transmission into PARK, or the
manual transmission into NEUTRAL, and turn the ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical loads.
• Connect one end of a jumper cable to the positive terminal of the booster battery.
Connect the other end of the same cable to the positive terminal of the discharged
battery.
• Connect the other cable, first to the negative terminal of the booster battery and then to
the engine ground (-) of the vehicle with the discharged battery. Make sure you have a
good contact on the engine ground.
• Start the engine in the vehicle which has the booster battery; let the engine idle a few
minutes.
• Start the engine in the vehicle with the discharged battery.
• When removing the jumper cables, reverse the above sequence exactly. Be careful of the
moving belts and fan.
