62 GETTING TO KNOW YOUR VEHICLE O PERATING T IPS Window Fogging Windshield Wiper De-Icer — If Equipped NOTE: Refer to the chart at the end of this section for suggested control settings for various weather conditions. Summer Operation Vehicle windows tend to fog on the inside in mild, rainy, and/or humid weather. To clear the windows, select Defrost or Mix mode and increase the front blower speed. Do not use the Recirculation mode without A/C for long periods, as fogging may occur. Outside Air Intake 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 engine cooling system must be protected with a high-quality antifreeze coolant to provide proper corrosion protection and to protect against engine overheating. OAT coolant (conforming to MS.90032) is recommended. Winter Operation 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). 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 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). To ensure the best possible heater and defroster performance, make sure the engine cooling system is functioning properly and the proper amount, type, and concentration of coolant is used. Use of the Air Recirculation mode during Winter months is not recommended, because it may cause window fogging.
Vacation/Storage Activation By Remote Start Operation When Remote Start is active 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 operation will continue. 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 For information on maintaining the Climate Control system when the vehicle is being stored for an extended period of time, see Ъ page426.
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.
