3. Disconnect the positive end (+) of the jumper cable from the positive (+) post of
the booster battery.
4. Disconnect the opposite end of the positive (+) jumper cable from the remote
positive (+) post of the discharged vehicle.
5. Close the cover of the Front Power Distribution Center.
NOTE:
Only use the specific negative post. Do not use any other exposed metal parts.
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 (e.g., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s battery discharges suffi-
ciently 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 the 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.
• Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property
damage due to battery explosion.
• 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.
