Did You Know?
If your engine begins overheating while driving in heavy traffic, the following steps can help alleviate the condition:

• Set the climate control system to "Heat" or "Vent"
• Set the blower fan on "High" (roll down your windows if the interior becomes too warm)
• Allow more distance between your vehicle and the one in front of you; this enables more air to enter the radiator easily

What It Does
The Heating and Air Conditioning System heats and cools the vehicle cabins and defrosts the windows.

Service & Maintenance
Your vehicles' Heating and Air Conditioning System should be checked by a professional technician approximately every 12 months (check your Owner's Manual for specific recommendations). Any related maintenance should be handled only by professionals.

If you notice any of the following conditions, have your vehicle checked right away:
Musty smell when the air conditioning or heating system is activated
Inadequate cooling or heating temperatures when using the air conditioning or heating system
