NOTE:
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.). Eventu-
ally, if plugged in long enough, the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from starting.
