NOTE: In cold weather, use of Recirculation mode may
lead to excessive window fogging. The recirculation
feature may be unavailable (button on the touchscreen
greyed out) if conditions exist that could create fogging
on the inside of the windshield. On systems with Manual
Climate Controls, the Recirculation mode is not allowed
in Defrost mode to improve window clearing operation.
Recirculation will be disabled automatically if this mode
is selected. Attempting to use Recirculation while in this
mode will cause the LED in the control button to blink
and then turn off.
Windshield Wiper De-icer — If Equipped
The windshield wiper de-icer is a heating element lo-
cated at the base of the windshield.
The windshield wiper de-icer operates automatically
once the following conditions are met:
• Activation By Front Defrost
The wiper de-icer activates automatically during a cold
weather manual start with full defrost, and when the
ambient temperature is below 33° F (0.6° C) .
• Activation By Rear Defrost
The wiper de-icer activates automatically when the Rear
Defrost is operating and the ambient temperature is
below 33° F (0.6° C) .
• Activation By Remote Start Operation
When the Remote Start is activated and the outside
ambient temperature is less than 33° F (0.6° C) the
windshield wiper de-icer is activated. Upon exiting Re-
mote Start, the climate control functions will resume their
previous operation except, if the de-icer is active, the
de-icer timer and operation will continue.
