Fill your engine coolant reservoir as outlined in Adding engine coolant

in this section.

Severe climates

If you drive in extremely cold climates:

• It may be necessary to increase the coolant concentration

above 50%.

• NEVER increase the coolant concentration above 60%.

• A coolant concentration of 60% will provide improved freeze

point protection. Increased engine coolant concentrations

above 60% will decrease the overheat protection

characteristics of the engine coolant and may cause engine

damage.

• If available, refer to the chart on the coolant container to

ensure the coolant concentration in your vehicle will provide

adequate freeze protection at the temperatures in which you

drive in the winter months.

If you drive in extremely hot climates:

• It is still necessary to maintain the coolant concentration

above 40%.

• NEVER decrease the coolant concentration below 40%.

• Decreased engine coolant concentrations below 40% will

decrease the corrosion/freeze protection characteristics of the

engine coolant and may cause engine damage.

• If available, 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 (if equipped)

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.
