Maintenance and Specifications Oil overheat can be triggered in severe driving conditions, such as towing heavy loads over mountainous terrain in extreme hot temperatures. As oil temperature increases, engine and vehicle speed will be limited. The transmission will also shift differently. When the engine oil has cooled, the vehicle will perform normally. When fail-safe cooling mode is activated You have limited engine power when in the fail-safe mode, so drive the vehicle with caution. Remember that the engine is capable of completely shutting down automatically to prevent engine damage, therefore: 1. Pull off the road as soon as safely possible and turn off the engine. 2. Arrange for the vehicle to be taken to an authorized dealer. 3. If this is not possible, wait approximately 15 minutes for the engine to cool. 4. Check the coolant level and replenish if low. Look for coolant leakage in the engine compartment and under the vehicle. 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 For fuel filter replacement, see your authorized dealer.
