through the instrument panel outlets. The
length of time needed for warm up will depend
on the outside temperature and the length
of time that has elapsed since your vehicle was
last driven.3. Adjust the PASS TEMP indicator that is
located below the temperature display. If

side will be adjust to the same temperature
setting as the driver side. Each bar that is lit to
the + side of the center bar indicates that
the passenger side will control to a warmer
setting than the driver side. Each bar lit to
the — side of the center bar indicates that the
passenger side will control to a cooler
