Seat Heaters
Push the right side of the switch, HI,
to rapidly heat up the seat. After the
seat reaches a comfortable
temperature, select LO by pushing
the left side of the switch. This will
keep the seat warm.

Follow these precautions when using
the seat heaters:
Do not use the seat heater in the
HI setting for an extended period,
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 even on the LO
setting. It can weaken the battery,
causing hard starting.
The heater runs continuously and
does not automatically turn off
after a period of time.
Heat induced burns are
possible when using seat
heaters.
Persons with a diminished
ability to sense temperature
(e.g., persons with diabetes,
lower-limb nerve damage, or
paralysis) or with sensitive skin
should not use seat heaters.
