•If your vehicle is equipped with Continuous Controlled Damping
Suspension (CCD Suspension), you can select NORMAL or SPORT
drive control modes for better experience while towing a trailer. See
the Information Displays chapter for details on selecting driving
modes.
• If you are towing a trailer frequently in hot weather, hilly conditions,
at the gross combined weight rating (or any combination of these
factors), consider refilling your rear axle with synthetic gear lubricant
(if the axle is not already filled with it). See the Capacities and
Specifications chapter for the lubricant specification.
• Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
• Avoid parking on a grade. However, if you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in position P.
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not included with vehicle.)
Your vehicle may be equipped with a temporary or conventional spare
tire. A “temporary” spare tire is different in size (diameter or width),
tread-type (All-Season or All-Terrain) or is from a different manufacturer
than the road tires on your vehicle. Consult information on the tire label
or Safety Compliance label for limitations when using.
Launching or Retrieving a Boat or Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer beforebacking the trailer into
the water.
Note: Reconnect the wiring to the trailer afterremoving the trailer from
the water.
When backing down a ramp during boat launching or retrieval:
• Do not allow the static water level to rise above the bottom edge of
the rear bumper.
• Do not allow waves to break higher than 6 inches (15 centimeters)
above the bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
• Causing internal damage to the components.
• Affecting driveability, emissions, and reliability.
Replace the rear axle lubricant anytime the rear axle submerges in
water. Water may have contaminated the rear axle lubricant, which does
not normally require checking or changing unless it is leaking or other
axle repair is required.

•Narrower – to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, sport-utility vehicles,
vans and trucks often will have a
higher center of gravity and a
greater difference in center of
gravity between the loaded and
unloaded condition.
These differences that make your
vehicle so versatile also make it
handle differently than an ordinary
passenger car.
TIRE CARE
Information About Uniform Tire Quality Grading Tire Quality Grades apply to new
pneumatic passenger car tires. The Tire
Quality Grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
• Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic passenger car tires. They do
not apply to deep tread, winter-type snow tires, space-saver or
temporary use spare tires, light truck or LT type tires, tires with nominal
rim diameters of 10 to 12 inches or limited production tires as defined in
Title 49 Code of Federal Regulations Part 575.104(c)(2).
U.S. Department of Transportation-Tire quality grades: The U.S.
Department of Transportation requires Ford Motor Company to give you
the following information about tire grades exactly as the government
has written it.

Information on P Type TiresP215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
A. P: Indicates a tire, designated by the Tire and Rim Association, that
may be used for service on cars, sport utility vehicles, minivans and light
trucks.
Note: If your tire size does not begin with a letter, this may mean it is
designated by either the European Tire and Rim Technical Organization
or the Japan Tire Manufacturing Association.
B. 215: Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
C. 65: Indicates the aspect ratio which gives the tire’s ratio of height to
width.
D. R: Indicates a radial type tire.
E. 15: Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
F. 95: Indicates the tire’s load index. It is an index that relates to how
much weight a tire can carry. You may find this information in your
owner’s manual. If not, contact a local tire dealer.
Note: You may not find this information on all tires because it is not
required by federal law.

Information on T Type TiresT type tires have some additional
information beyond those of P type
tires. These differences are
described below.
T145/80D16 is an example of a tire
size.
Note:The temporary tire size for
your vehicle may be different from
this example. Tire Quality Grades
do not apply to this type of tire.
A. T:Indicates a type of tire, designated by the Tire and Rim
Association, that is intended for temporary service on cars, sport-utility
vehicles, minivans and light trucks.
B. 145: Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
C. 80: Indicates the aspect ratio, which gives the tire’s ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
D. D: Indicates a diagonal type tire. R:Indicates a radial type tire.
E. 16: Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
Location of the Tire Label
You will find a Tire Label containing tire inflation pressure by tire size
and other important information located on the B-Pillar or the edge of
the driver’s door. See the payload description and graphic in the Load
Carrying chapter.
