Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.

Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.

What you should know about fail-safe cooling (2.5L I4 engine only)

If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.

How fail-safe cooling works

If the engine begins to overheat:

The engine coolant temperature gauge will move to the red (hot)
area.

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 and the engine
will completely shut down, causing steering and braking effort to
increase.

Once the engine temperature cools, the engine can be re-started. Take
your vehicle to an authorized dealer 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.
