Front power seat adjustment
Operating tips:
.The power seat motor has an auto-reset
overload protection circuit. If the motor
stops during operation, wait 30 seconds,
then reactivate the switch.
. Do not operate the power seat switch for
a long period of time when the engine is
off. This will discharge the battery.
