• Start the engine in the vehicle that has the booster battery, let the engine idle a
few minutes, and then start the engine in the vehicle with the discharged
battery.
Once the engine is started, remove the jumper cables in the reverse sequence:
• Disconnect the negative (-) jumper cable from the engine ground of the vehicle
with the discharged battery.
• Disconnect the negative end (-) of the jumper cable from the negative (-) post of
the booster battery.
• Disconnect the opposite end of the positive (+) jumper cable from the positive
(+) post of the booster battery.
• Disconnect the positive (+) end of the jumper cable from the positive (+) post of
the discharged vehicle.
• Reinstall the air intake duct.
• If frequent jump-starting is required to start your vehicle you should have the
battery and charging system inspected at your authorized dealer.
CAUTION!
• Do not use a portable battery booster pack or any other booster source with a
system voltage greater than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
• Failure to follow these procedures could result in damage to the charging
system of the booster vehicle or the discharged vehicle.
• Accessories that can be plugged into the vehicle power outlets draw power
from the vehicle’s battery, even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s battery will discharge
sufficiently to degrade battery life and/or prevent the engine from starting.
WARNING!
• When temperatures are below the freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump-starting because the battery could
rupture or explode and cause personal injury. Battery temperature must be
brought above freezing point before attempting a jump-start.
• 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 severely 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.
