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
battery even more quickly. Only use these inter-
mittently and with greater caution.
(Continued)
CAUTION! (Continued)
• 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.
