SERVICE RIDE CONTROL If a problem occurs with the suspension system, this message will appear on the DIC. If this message appears, stop and turn off the vehicle. Restart the vehicle and check for the message on the DIC display. If the message is still displayed, or appears again when you begin driving, the air suspension system needs service. TRANSMISSION HOT If the transmission fluid temperature becomes high, the message center will display this message. 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. TIGHTEN FUEL CAP If the vehicle's fuel cap is not tightened properly thsi message may appear along with the check engine light on the instrument panel. See Malfunction Indicator Lamp on page 3-49. Fully reinstall the fuel cap. See Filling Your Tank on page 5-7. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light and message off. 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: TRACTION ACTIVE When the traction control system had detected that any of the vehicle's wheels are slipping, the traction control system will activate and this message will appear on the DIC. For more information see "Traction Assist" in the Index. Towing a trailer Hot outside air temperatures Hauling a large or heavy load Low transmission fluid level High transmission fluid level Restricted air flow to the radiator and the auxiliary transmission oil cooler. 3-71
