Driving -> ENGINE BLOCK HEATER for Your Ford Explorer SUV Fifth Generation (2005-2011)

Driving  
ENGINE BLOCK HEATER (IF EQUIPPED)  
An engine block heater warms the engine coolant which aids in starting  
and allows the heater/defroster system to respond quickly. If your vehicle  
is equipped with this system, your equipment includes a heater element  
which is installed in your engine block and a wire harness which allows  
the user to connect the system to a grounded 120 volt A/C electrical  
source. The block heater system is most effective when outdoor  
temperatures reach below 0°F (-18°C).  
WARNING: Failure to follow engine block heater instructions  
could result in property damage or physical injury.  
WARNING: To reduce the risk of electrical shock, do not use  
your heater with ungrounded electrical systems or two-pronged  
(cheater) adapters.  
Prior to using the engine block heater, follow these recommendations for  
proper and safe operation:  
For your safety, use an outdoor extension cord that is product  
certified by Underwriter’s Laboratory (UL) or Canadian Standards  
Association (CSA). Use only an extension cord that can be used  
outdoors, in cold temperatures, and is clearly marked “Suitable for Use  
with Outdoor Appliances.” Never use an indoor extension cord  
outdoors; it could result in an electric shock or fire hazard.  
Use a 16 gauge outdoor extension cord, minimum.  
Use as short an extension cord as possible.  
Do not use multiple extension cords. Instead, use one extension cord  
which is long enough to reach from the engine block heater cord to  
the outlet without stretching.  
Make certain that the extension cord is in excellent condition (not  
patched or spliced). Store your extension cord indoors at  
temperatures above 32°F (0°C). Outdoor conditions can deteriorate  
extension cords over a period of time.  
To reduce the risk of electrical shock, do not use your heater with  
ungrounded electrical systems or two pronged (cheater) adapters.  
Also ensure that the block heater, especially the cord, is in good  
condition before use.  
Make sure that when in operation, the extension cord plug/engine  
block heater cord plug connection is free and clear of water in order  
to prevent possible shock or fire.

Driving  
Be sure that areas where the vehicle is parked are clean and clear of  
all combustibles such as petroleum products, dust, rags, paper and  
similar items.  
Be sure that the engine block heater, heater cord and extension cord  
are solidly connected. A poor connection can cause the cord to  
become very hot and may result in an electrical shock or fire. Be sure  
to check for heat anywhere in the electrical hookup once the system  
has been operating for approximately a half hour.  
Finally, have the engine block heater system checked during your fall  
tune-up to be sure it’s in good working order.  
How to use the engine block heater  
Ensure the receptacle terminals are clean and dry prior to use. To clean  
them, use a dry cloth.  
Depending on the type of factory installed equipment, your engine block  
heater will use .4 to 1.0 kilowatt-hours of energy per hour of use. Your  
factory installed block heater system does not have a thermostat;  
however, maximum temperature is attained after approximately three  
hours of operation. Block heater operation longer than three hours will  
not improve system performance and will unnecessarily use additional  
electricity.  
Make sure system is unplugged and properly stowed before driving the  
vehicle. While not in use, make sure the protective cover seals the  
prongs of the engine block heater cord plug.  
BRAKES  
Occasional brake noise is normal. If a metal-to-metal, continuous grinding  
or continuous squeal sound is present, the brake linings may be worn-out  
and should be inspected by an authorized dealer. If the vehicle has  
continuous vibration or shudder in the steering wheel while braking, the  
vehicle should be inspected by an authorized dealer.

Four-wheel anti-lock brake system (ABS)  
Your vehicle is equipped with an anti-lock braking system (ABS). This  
system helps you maintain steering control during emergency stops by  
keeping the brakes from locking. Noise from the ABS pump motor and
