Dual Automatic Climate Control
System
With this system you can control the heating,
cooling, and ventilation for your vehicle.
If your vehicle has the remote start feature and it is
activated, the climate control system will heat and
cool the inside of the vehicle, using the previous
system settings before the vehicle was turned off.
The rear window defogger will be turned on by the
climate control system when it is cold outside. If the
vehicle has heated seats, they will also turn on.
Cooled seats are not activated during a remote
start. Normal operation of the system will return
after the key is turned to the RUN position. See
Remote Keyless Entry (RKE) System Operation
on page 95for more information.

vehicle warms up to maintain the chosen
temperature setting. The length of time needed
to warm the interior will depend on the outside
