heating. Pressing the switch a second time will select
low-level heating. Pressing the switch a third time will
shut the heating elements off.
When high-temperature heating is selected, the heaters
provide a boosted heat level during the first four minutes
of operation after heating is activated. The heat output
then drops to the normal high-temperature level. If
high-level heating is selected, the system will automati-
cally switch to the low level after 30 minutes of continu-
ous operation. At that time, the number of illuminated
LEDs changes from two to one, indicating the change.
Operation on the low setting also turns off automatically
after 30 minutes.
NOTE: Once a heat setting is selected, heat will be felt
within two to five minutes.
WARNING!
Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time.
Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This may
cause the seat heater to overheat.
