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.

Engine fluid temperature management (EcoBoost™ engine only)

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.

You may notice a reduction in the vehicle’s speed caused by reduced

engine power. Your vehicle has been designed to enter this mode if
