Maintenance You have limited engine power when in the fail-safe mode, so drive your vehicle with caution. Your vehicle will not maintain high-speed operation and the engine will operate poorly. Remember that the engine is capable of automatically shutting down to prevent engine damage. In this situation: 1. Pull off the road as soon as safely possible and switch off the engine. 2. Tow your vehicle to an authorized dealer. 3. If this is not possible, wait a short period for the engine to cool. 4. Check the coolant level and add if low. 5. Re-start the engine and drive your vehicle to an authorized dealer. Note: Driving your vehicle without repair increases the chance of engine damage. Contact an authorized dealer as soon as possible. Engine Fluid Temperature Management (If Equipped) WARNINGS To reduce the risk of crash and injury, be prepared that the vehicle speed may reduce and the vehicle may not be able to accelerate with full power until the fluid temperatures reduce. Never remove the coolant reservoir cap while the engine is running or hot. Your vehicle can pull a trailer, but because of the added load, your vehicle's engine may temporarily reach higher temperatures during severe operating conditions such as ascending a long or steep grade while pulling a trailer in high temperatures. At this time, you may notice your engine coolant temperature gauge needle move toward the H and the POWER REDUCED TO LOWER TEMP message may appear in the information display. You may notice a reduction in vehicle speed caused by reduced engine power. In order to manage the engine fluid temperatures, your vehicle may enter this mode if certain high-temperature and high-load conditions take place. The amount of speed reduction depends on many factors such as vehicle loading, towing, grade and ambient temperature. If this occurs, there is no need to pull off the road. You can continue to drive your vehicle while this message is active. The air conditioning may also cycle on and off during severe operating conditions to protect overheating of the engine. When the engine coolant temperature decreases to a normal operating temperature, the air conditioning will turn on once again. If the engine coolant temperature gauge moves fully into the red (hot) area, or if the coolant temperature warning or service engine soon messages appear in your information display: 1. Pull off the road as soon as safely possible and shift the transmission into P. 2. Leave the engine running until the coolant temperature gauge needle moves away from the red (hot) area. After several minutes, if the temperature does not drop, follow the remaining steps. 3. Switch the engine off and wait for it to cool before checking the coolant level. 4. If the coolant level is normal, restart your engine and continue. 306 F-150 (), enUSA, First Printing
