REAR WINDOW DEFROSTER (IF EQUIPPED) R
The rear defroster control is located on the climate control panel and
works to defrost your rear window from fog and thin ice. If equipped, it
also operates the heated mirror to remove snow and thin ice from the
side mirrors.
Ensure that the ignition on. Press to turn the defroster on/off. The
indicator light will illuminate when activated. For vehicles with a sliding
rear window– the defroster will be disabled when the window is opened.
Do not use razor blades or other sharp objects to clean the inside
of the rear window or to remove decals from the inside of the
rear window. This may cause damage to the heated grid lines and
will not be covered by your warranty.
REMOTE START CLIMATE OPERATION (IF EQUIPPED)
The climate control system will condition the cabin temperature during
remote start based on the outside temperature. Engine idle may increase
to help with adjusting the cabin temperature.
Note: No climate control adjustments will be recognized during remote
start operation. Once the ignition is cycled to the on position, the climate
control system will return to the previous settings (last ignition-on cycle)
and adjustments can be made normally. If the previous setting was off,
the climate control system will turn off.
