ENGINE PROTECTION REDUCE ENGINE RPM: If this message appears, the control system has determined that continued operation at the existing engine speed may lead to engine overheating. Therefore, you should lower the engine speed by upshifting the transmission or drive at a lower speed. HEADLAMPS SUGGESTED: If it's dark enough outside and the headlamps and Twilight Sentinel® controls are off, this message will display on the DIC. This message informs the driver that turning on the exterior lamps is recommended even though the DRL are still illuminated. It has become dark enough outside to require the headlamps and/or other exterior lamps. This message will also appear if the optional Rainsense™ wiping feature is on and the Twilight Sentinel® is off. HIGH TRANS TEMP: This message indicates that the transaxle fluid in your vehicle is too hot. Stop and allow your vehicle to idle until it cools down or until this message is removed. HIGH VOLTAGE: This message shows that the electrical charging system is overcharging. To avoid being stranded, have the electrical system checked by your dealership. You can reduce the charging overload by using the accessories. Turn on the lamps and radio, set the climate control on AUTO and the fan speed on HI, and turn the rear window defogger on. You can monitor battery voltage on the DIC by pressing the INFO button. The normal range is 11.5 to 15.5 volts when the engine is running. HOT ENGINE-A/C OFF: This message displays when the engine coolant becomes hotter than the normal operating temperature. To avoid added strain on a hot engine, the air conditioning compressor is automatically turned off. When the coolant temperature returns to normal, the A/C operation will automatically resume. You can continue to drive your vehicle. If this message continues to appear, have the system repaired as soon as possible to avoid compressor damage. ICE POSSIBLE: This message appears when the outside air temperature is cold enough to create icy road conditions. LEFT DOOR AJAR: This message will display anytime the vehicle engine is running, the transmission is not in PARK (P) and the driver's door is open or ajar. A chime will sound when the vehicle's speed is greater than 3 mph (4.8 km/h). LOW BRAKE FLUID: This message will display if the vehicle is running to inform the driver that the brake fluid level is low. Have the brake system serviced by a technician as soon as possible. See "Brake Fluid" under Brakes on page 5-35. 3-61
