IF YOUR VEHICLE OVERHEATS WARNING Do not continue to drive if your vehicle overheats. Doing so could cause engine damage or a vehicle fire. To avoid the danger of being scalded, never remove the radiator cap while the engine is still hot. When the radiator cap is removed, pressurized hot water will spurt out, possibly causing serious injury. Do not open the hood if steam is coming out. If your vehicle is overheating (indicated by an extremely high temperature gauge reading), or if you feel a lack of engine power, detect abnormal noise, etc., take the following steps: 1. Move the vehicle safely off the road, apply the parking brake and move the selector lever to P (Park). Do not stop the engine. 2. Turn off the climate control. Open all the windows, move the heater or air conditioner temperature control to maximum hot and fan control to high speed. 3. If engine overheating is caused by climbing a long hill on a hot day, run the engine at a fast idle (approximately 1,500 rpm) until the temperature gauge indication returns to normal. 4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radiator before opening the hood (If steam or coolant is escaping, turn off the engine.). Do not open the hood further until no steam or coolant can be seen. 5. Open the engine hood. WARNING Be careful not to allow your hands, hair, jewelry or clothing to come into contact with, or get caught in, engine belts or the engine cooling fan. The engine cooling fan can start at any time when the coolant temperature is high. 7. After the engine cools down, check the coolant level in the reservoir tank with the engine running. Add coolant to the reservoir tank if necessary. Have your vehicle repaired at the nearest INFINITI dealer. If needed, Roadside Assistance is available. Please see your Warranty Information Booklet or Roadside Assistance I.D. Card for the toll-free number to call (U.S.) or Warranty & Roadside Assistance Information Booklet (Canada). WARNING If steam or water is coming from the engine, stand clear to prevent getting burned. 6. Visually check if the cooling fan is running. The radiator hoses and radiator should not leak water. If coolant is leaking, or the cooling fan does not run, stop the engine. In case of emergency 6-11
