TRANSMISSION HOT If the transmission fluid temperature becomes high, this message will appear on the DIC. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. When the transmission fluid temperature returns to normal, the display will turn off and the transmission shifting patterns will return to normal. Notice: If you drive your vehicle while the transmission fluid is overheating and the transmission temperature warning is displayed on the instrument panel cluster and/or DIC, you can damage the transmission. This could lead to costly repairs that would not be covered by your warranty. Do not drive your vehicle with overheated transmission fluid or while transmission temperature warning is displayed. The following situations can cause the transmission to operate at higher temperatures: • Low transmission fluid level • High transmission fluid level • Restricted air flow to the radiator and the auxiliary transmission oil cooler A temporary solution to hotter transmission operating temperatures may be to let the transmission cool down. If the transmission is operated at higher temperatures on a frequent basis, see Scheduled Maintenance on page 6-4 for the proper transmission maintenance intervals. TURN SIGNAL ON If a turn signal is left on for 3/4 of a mile (1.2 km), this message will appear on the display and you will hear a chime. Move the turn signal/multifunction lever to the off position. Pressing any of the four DIC buttons, if equipped, will acknowledge the message and clear it from the DIC display. If your vehicle is not equipped with the four DIC buttons, pressing the trip odometer reset stem will acknowledge the message and clear it from the DIC display.
