Once the TPM system detects the low or high tire pressure condition, the message "CHECK TIRE PRESSURE" will be displayed whenever you start the engine or the ignition is in the ON position. To remove or clear the CHECK TIRE PRESSURE message, you will need to set the tire(s) to the proper tire pressure. See "Inflation -- Tire Pressure" in the Index. CHECK WASHER FLUID - 25: This message will appear to indicate that the washer solvent container needs refilling. DRIVER DOOR AJAR - 140: The driver's door is open or ajar when this message appears. The ignition must be in ON and the transaxle not in PARK (P) for this message to display. A chime will also sound when the vehicle's speed is greater than 3 mph (5 km/h). DRIVER NO. X (1 OR 2): This message will be displayed with the key in ON and while entering Feature Programming, but only if the vehicle is equipped with memory seats. The message will show which driver is activating the personalization feature. It will only stay on for five seconds. This message can be customized for you by your dealer. ENGINE COOLANT HOT, IDLE ENGINE - 44: This message will appear when the engine coolant temperature is over 262_F (128_C). Stop and allow your vehicle to idle in PARK (P) until it cools down and the message is removed. Do not increase engine speed above a normal idle. If it does not cool down, turn off the engine and have it serviced before driving it again. Severe engine damage can result from an overheated engine. See "Engine Overheating" in the Index. CAUTION: When the CHECK TIRE PRESSURE message is displayed on the Driver Information Center and the tire pressure is low, your vehicle handling capabilities will be reduced during severe maneuvers. If you drive too fast, you could lose control of your vehicle. You or others could be injured. Don't drive over 55 mph (90 km/h) when the tire pressure is low. Drive cautiously and correct the tire pressure as soon as you can. 2-102
