UNDERSTANDING THE FEATURES OF YOUR VEHICLE 203
Since this outlet is remote from the driver, it is powered
by the ignition switch, only when it is in the ON or
ACCESSORY positions, to protect the battery against
discharge. Note: Neither of the power outlets will accept
a cigar lighter unit. They are intended only for accessory
usage.
