HEATED STEERING WHEEL SYSTEM : System DescriptionINFOID:0000000009461247
The heated steering wheel switch c ontrols the heated steering relay through the A/C Auto amp. When the
switch is turned on, the relay is energized and t he heated steering system will operate. The heated steering
system will turn off when the steering w heel temperature reaches approximately 86 ° F (30 ° C). Heated steer-
ing system operation can also be canceled by pressing t he heated steering wheel switch again. If the surface
temperature of the steering wheel is below 68 ° F (20 ° C), the system will heat the steering wheel and cycle off
and on to maintain a temperature above 68 ° F (20 ° C). The indicator light will remain on as long as the system
is on.
