Maintenance the coolant temperature warning light will illuminate the service engine soon indicator will illuminate. If the engine reaches a preset over-temperature condition, the engine automatically switches to alternating cylinder operation. Each disabled cylinder acts as an air pump and cools the engine. When this occurs, your vehicle will still operate. However: • The engine power will be limited. • This will disable the air conditioning system. Continued operation increases the engine temperature, causing the engine to completely shut down. Your steering and braking effort increases in this situation. When the engine temperature cools, you can re-start your engine. Take your vehicle to an authorized dealer as soon as possible to minimize engine damage. When Fail-Safe Mode Is Activated WARNINGS Fail-safe mode is for use during emergencies only. Operate your vehicle in fail-safe mode only as long as necessary to bring your vehicle to rest in a safe location and seek immediate repairs. When in fail-safe mode, your 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. Never remove the coolant reservoir cap while the engine is running or hot. 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. 243 MKS (), enUSA
