How fail-safe cooling works

If the engine begins to overheat:

• The engine coolant temperature

gauge will move to the red (hot)

area.

• The “engine coolant temperature”

indicator will illuminate.

• The Service engine soon indicator light will illuminate.

If the engine reaches a preset over-temperature condition, the engine

will automatically switch to alternating cylinder operation. Each disabled

cylinder acts as an air pump and cools the engine.

When this occurs the vehicle will still operate. However:

• The engine power will be limited.

• The air conditioning system will be disabled.

Continued operation will increase the engine temperature:

• The engine will completely shut down.

• Steering and braking effort will increase.

Once the engine temperature cools, the engine can be re-started. Take

your vehicle to a service facility as soon as possible to minimize engine

damage.

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 a service facility.

3. If this is not possible, wait a short period for the engine to cool.

4. Check the coolant level and replenish if low.

Never remove the coolant reservoir cap while the engine is

running or hot.

5. Restart the engine and take your vehicle to a service facility.
