When fail-safe mode is activated

You have limited engine power when in the fail-safe mode, so drive the

vehicle with caution. The vehicle will not be able to maintain high speed

operation and the engine will run rough. 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 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.

Engine fluid temperature management (if equipped)

Your vehicle has been designed to pull a trailer, but because of the added

load, the 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 hot ambient 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 on the message center.
