WHAT TO DO IN EMERGENCIES 431
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories 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 without engine operation,
the vehicle's battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
