OPERATING TIPS
CAUTION
Interior air enters the Rear Automatic Temperature Control system through an intake grille, located in the right side trim panel behind the third-row seats. The heater outlets are located in the right side trim panel, just behind the rear doors. Do not block or place objects directly in front of the inlet grille or heater outlets. The electrical system could overload causing damage to the blower motor.
NOTE: Refer to the chart at the end of this section for suggested control settings for various weather conditions.
Summer Operation
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. For more information, see page 405.
Winter Operation
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 are used. Use of the Air Recirculation mode during the winter months is not recommended, because it may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control system when the vehicle is being stored for an extended period of time, see page 396
Window Fogging
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
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 the 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 Windshield 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 Windshield 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 operation will continue.
