Maintenance and Specifications 3. If this is not possible, wait a short period for the engine to cool. 4. Check the coolant level and replenish if low. WARNING: Fail-safe mode is for use during emergencies only. Operate the vehicle in fail-safe mode only as long as necessary to bring the vehicle to rest in a safe location and seek immediate repairs. When in fail-safe mode, the vehicle will have limited power, will not be able to maintain high-speed operation, and may completely shut down without warning, potentially losing engine power, power steering assist, and power brake assist, which may increase the possibility of a crash resulting in serious injury. WARNING: Never remove the coolant reservoir cap while the engine is running or hot. 5. Restart the engine and take your vehicle to an authorized dealer. Driving the vehicle without repairing the engine problem increases the chance of engine damage. Take your vehicle to an authorized dealer as soon as possible. FUEL FILTER Your vehicle is equipped with a lifetime fuel filter that is integrated with the fuel tank. Regular maintenance or replacement is not needed. For Shelby fuel filter requirements, see the Shelby GT500 Supplement. WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS Important safety precautions WARNING: Do not overfill the fuel tank. The pressure in an overfilled tank may cause leakage and lead to fuel spray and fire. WARNING: The fuel system may be under pressure. If you hear a hissing sound near the fuel filler door (Easy Fuel™ "no cap" fuel system), do not refuel until the sound stops. Otherwise, fuel may spray out, which could cause serious personal injury. WARNING: Automotive fuels can cause serious injury or death if misused or mishandled. 285 2011 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)
