CHANGE ENGINE OIL
This message is displayed when the engine oil
needs to be changed.
When you change the engine oil, be sure to reset
the CHANGE ENGINE OIL message. See
Engine Oil Life System (Gasoline Engine) on
page 485, Engine Oil (Gasoline Engine) on
page 482, and Scheduled Maintenance (Gasoline
Engine) on page 613 for more information.
CHARGING SYSTEM FAILURE
On some vehicles, if there is a problem with the
generator and battery charging system, this
message will appear on the DIC, a chime will
sound, and the battery warning light on the
instrument panel cluster will come on. Driving with
this problem could drain the battery. Turn off all
unnecessary accessories. Stop and turn off the
vehicle as soon as it is safe to do so. Have the
electrical system checked by your dealer
immediately. See Battery Warning Light on
page 250 and Voltmeter Gage on page 251 for
more information.
CHECK OIL LEVEL
If your vehicle has an oil level sensor, and the oil
level in the vehicle is low, this message will
appear on the DIC. Check the oil level and correct
it as necessary. You may need to let the vehicle
cool or warm up and cycle the ignition to be
sure this message will clear. Once the problem is
corrected, pressing any of the four DIC buttons
will acknowledge the message and clear it from the
DIC display. If your vehicle does not have the
four DIC buttons, pressing the trip odometer reset
stem will acknowledge the message and clear
it from the DIC display. See Engine Oil (Gasoline
Engine) on page 482 for additional information.
CHECK WASHER FLUID
If the washer fluid level is low, this message will
appear on the DIC. See Windshield Washer
Fluid on page 512. Adding washer fluid to the
windshield washer reservoir will clear the
message. Pressing any of the four DIC buttons
will acknowledge the message and clear it from the
DIC display. If your vehicle does not have the
four DIC buttons, pressing the trip odometer reset
stem will acknowledge the message and clear
it from the DIC display.
