Seat Heaters and Seat Ventilation (Canadian models)
Follow these precautions whenever
you use the seat heaters and the seat
ventilation:
Use the HI setting only to heat or
to ventilate the seats quickly,
because it draws large amounts of
current from the battery.
If the engine is left idling for an
extended period, do not use the
seat heaters or the seat ventilation,
even on the LO setting. It can
weaken the battery, causing hard
starting.
