WHAT TO DO IN EMERGENCIES CAUTION! Continuous driving with the Transmission Temperature HOTOIL Warning message illuminated will eventually cause severe transmission damage and transmission failure. WARNING! Continued operation with the Transmission Temperature HOTOIL Warning message illuminated could cause the fluid to boil over, come into contact with the hot engine or exhaust components causing a fire that may result in personal injury. IF YOUR ENGINE OVERHEATS • In any of the following situations, you can reduce the potential for overheating by taking the appropriate action. • On the highways - slow down. • In city traffic - while stopped, shift transmission into NEUTRAL, but do not increase engine idle speed. NOTE: There are steps that you can take to slow down an impending overheat condition: • If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat. • You can also turn the Temperature Control to maximum heat, the Mode Control to floor and the Fan Control to high. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system. • If the temperature reading does not return to normal, turn the engine off immediately. • We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately. CAUTION! Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air conditioner turned off until the pointer drops back into the normal range. If the pointer remains on HOT (H), and you hear continuous chimes, turn the engine off immediately and call for service. 58
