TEMPERATURE CONTROL
General Hints
Note:Prolonged use of recirculated air maycause the windows to fog up.
Note:You may feel a small amount of airfrom the footwell air vents regardless of theair distribution setting.
Note:To reduce humidity build-up insideyour vehicle, do not drive with the systemswitched off or with recirculated air alwaysswitched on.
Note:Do not place objects under the frontseats as this may interfere with the airflowto the rear seats.
Note:Remove any snow, ice or leaves fromthe air intake area at the base of thewindshield.
Note:To improve the time to reach acomfortable temperature in hot weather,drive with the windows open until you feelcold air through the air vents.
Automatic Climate Control
Note:Adjusting the settings when yourvehicle interior is extremely hot or cold isnot necessary. Automatic mode is bestrecommended to maintain set temperature.
Note:The system adjusts to heat or coolthe interior to the temperature you selectas quickly as possible.
Note:For the system to function efficiently,the instrument panel and side air ventsshould be fully open.
Note:If you select AUTO during coldoutside temperatures, the system directsair flow to the windshield and side windowair vents. In addition, the blower motor mayrun at a slower speed until the engine warmsup.
Note:If you select AUTO during hottemperatures and the inside of the vehicleis hot, the system uses recirculated air tomaximize interior cooling. Blower motorspeed may also reduce until the air cools.

Important Ventilating Information
If you stop your vehicle and the leave theengine idling for long periods, werecommend that you do one of thefollowing:
•Open the windows at least 1 in(2.5 cm).
•Set your climate control to outside air.
ENGINE BLOCK HEATER (IF
EQUIPPED)
WARNING: Failure to follow engineblock heater instructions could result inproperty damage or serious personalinjury.
WARNING: Do not use your heaterwith ungrounded electrical systems ortwo-pronged adapters. There is a risk ofelectrical shock.
WARNING: Do not fully close thehood, or allow it to drop under its ownweight when using the engine blockheater. This could damage the powercable and may cause an electrical shortresulting in fire, injury and propertydamage.
Note:The heater is most effective whenoutdoor temperatures are below 0°F(-18°C).
The heater acts as a starting aid bywarming the engine coolant. This allowsthe climate control system to respondquickly. The equipment includes a heaterelement, installed in the engine block anda wire harness. You can connect thesystem to a grounded 120-volt ACelectrical source.
We recommend that you do the followingfor a safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified byUnderwriter’s Laboratory (UL) orCanadian Standards Association(CSA). This extension cord must besuitable for use outdoors, in coldtemperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and heater cordplug connections are free and clear ofwater. This could cause an electricshock or fire.
•If the block heater cord is under thehood, Do Not remove the wiring fromits original location. Do Not close thehood on the extension wiring.
•Make sure your vehicle is parked in aclean area, clear of combustibles.
•Make sure the heater, heater cord andextension cord are firmly connected.
•Check for heat anywhere in theelectrical hookup once the system hasbeen operating for approximately 30minutes.

Battery Management System (If
Equipped)
The system monitors battery conditionsand takes actions to extend battery life. Ifexcessive battery drain is detected, thesystem temporarily disables someelectrical systems to protect the battery.
Systems included are:
•Heated rear window.
•Heated seats.
•Climate control.
•Heated steering wheel.
•Audio unit.
•Navigation system.
A message may appear in the informationdisplay to alert you that battery protectionactions are active. This message is only fornotification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
After battery replacement, or in somecases after charging the battery with anexternal charger, the battery managementsystem requires eight hours of vehicle sleeptime to relearn the battery state of charge.During this time, your vehicle must remainfully locked with the ignition switched off.
Note:Prior to relearning the battery stateof charge, the battery management systemmay temporarily disable some electricalsystems.
Electrical Accessory Installation
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connectiondirectly to the battery negative post. Thiscan cause inaccurate measurements ofthe battery condition and potentialincorrect system operation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.
