TRAILER TOWING
Trailer towing with your vehicle may require the use of a trailer tow
option package.
Trailer towing puts additional loads on your vehicle's engine,
transmission, axle, brakes, tires, and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
When towing maximum loads under high outside temperatures and on
steep grades, the A/C system may cycle on and off to protect the engine
from overheating. This may result in a temporary increase of interior
temperatures.
Follow these guidelines to ensure safe towing procedure:
²Stay within your vehicle's load limits.
²Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
²Use extra caution when driving while trailer towing. Refer toDriving
while you towin this chapter.
²Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the scheduled maintenance guide.
²Do not tow a trailer until your vehicle has been driven at least 800 km
(500 miles).
²Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
Do not exceed the maximum loads listed on the Safety Compliance
Certification label. For load specification terms found on the label, refer
toVehicle loadingin this chapter. Remember to figure in the tongue
load of your loaded vehicle when figuring the total weight.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Ford specification WSB-M8B16±A2.
Refer toLubricant specifications
in this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle's paint finish, wiper blades or washer system.
If you operate your vehicle in temperatures below 4.5É C (40É
F), use washer fluid with antifreeze protection. Failure to use
washer fluid with antifreeze protection in cold weather could result in
impaired windshield vision and increase the risk of injury or accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
