258 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
WARNING!
To avoid serious injury or death:
• Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
• Many accessories that can be plugged in 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.
• Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the bat-
tery even more quickly. Only use these intermit-
tently and with greater caution.
• After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle's battery.
