GETTING TO KNOW YOUR VEHICLE 75
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstructions,
such as leaves. Leaves collected in the air
intake may reduce airflow, and if they enter the
air distribution box, they could plug the water
drains. In Winter months, make sure the air
intake is clear of ice, slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized
dealer to service your cabin air filter, and to
have it replaced when needed.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control
system may automatically adjust airflow to
maintain cabin comfort. Customer settings will
be maintained upon return to an engine running
condition.
Windshield Wiper De-Icer — If Equipped
The windshield wiper de-icer is a heating
element located at the base of the windshield.
It 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
will activate. Exiting remote start will resume
its previous operation. If the Windshield
Wiper De-Icer was active, the timer and oper-
ation will continue.
