Battery Load Management
This feature monitors the vehicle’s electrical load anddetermines when the battery is in a heavy dischargecondition. During times of high electrical loading,the engine may idle at a higher revolutions per minute(rpm) setting than normal to make sure the batterycharges. High electrical loads may occur when severalof the following are on: headlamps, high beams, foglamps, rear window defogger, the climate control fan athigh speeds, heated seats and engine cooling fans.
If the battery continues to discharge, even withthe engine idling at a higher rpm setting, some electricalloads will automatically be reduced. When this occurs,the rear window defogger may take slightly longerto clear the glass, the heated seats may not get as warmas they usually do and the climate control fan may cutback to a lower speed. For more battery savinginformation, see “Battery Saver Active Message” underDIC Warnings and Messages on page 4-67.

Warning lights and gages can signal that something iswrong before it becomes serious enough to causean expensive repair or replacement. Paying attention tothe warning lights and gages could prevent injury.
Warning lights come on when there might be or there isa problem with one of the vehicle’s functions. Somewarning lights come on briefly when the engine is startedto indicate they are working.
Gages can indicate when there might be or there is aproblem with one of the vehicle’s functions. Often gagesand warning lights work together to indicate a problemwith the vehicle.
When one of the warning lights comes on and stays onwhile driving, or when one of the gages shows therecould be a problem, check the section that explains whatto do. Follow this manual’s advice. Waiting to dorepairs can be costly and even dangerous.
