system. This system is designed to prevent the engine from being started
unless acoded key programmed to your vehicleis used.
The SecuriLock
passive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.
THEFT INDICATOR
The theft indicator is the flashing red indicator located on the dash
panel.
•When the ignition is in the 1 (OFF/LOCK) position, the indicator will
flash once every 2 seconds to indicate the SecuriLock
system is
functioning as a theft deterrent.
•When the ignition is in the 3 (ON) position, the indicator will glow for
3 seconds to indicate normal system functionality.
If a problem occurs with the SecuriLock
system, the indicator will flash
rapidly or glow steadily when the ignition is in the 3 (ON) position. If
this occurs, the vehicle should be taken to an authorized dealer for
service.

WASHING THE EXTERIOR
Wash your vehicle regularly with cool or lukewarm water and a neutral
Ph shampoo, such as Motorcraft Detail Wash (ZC-3–A), which is available
from your dealer.
•Never use strong household detergents or soap, such as dish washing
or laundry liquid. These products can discolor and spot painted
surfaces.
•Never wash a vehicle that is“hot to the touch”or during exposure to
strong, direct sunlight.
•Always use a clean sponge or car wash mitt with plenty of water for
best results.
•Dry the vehicle with a chamois or soft terry cloth towel in order to
eliminate water spotting.
•It is especially important to wash the vehicle regularly during the
winter months, as dirt and road salt are difficult to remove and cause
damage to the vehicle.
•Immediately remove items such as gasoline, diesel fuel, bird droppings
and insect deposits because they can cause damage to the vehicle’s
paintwork and trim over time.
•Remove any exterior accessories, such as antennas, before entering a
car wash.
•Suntan lotions and insect repellents can damage any painted
surface; if these substances come in contact with your vehicle,
wash off as soon as possible.
WAXING
Applying a polymer paint sealant to your vehicle every six months will
assist in reducing minor scratches and paint damage.
•Wash the vehicle first.
•Do not use waxes that contain abrasives.
•Do not allow paint sealant to come in contact with any non-body
(low-gloss black) colored trim, such as grained door handles, roof
racks, bumpers, side moldings, mirror housings or the windshield cowl
area. The paint sealant will“gray”or stain the parts over time.
PAINT CHIPS
Your dealer has touch-up paint and sprays to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jam) to
your dealer to ensure you get the correct color.

Letter rating Speed rating - mph (km/h)
Note:For tires with a maximum speed capability over 149 mph
(240 km/h), tire manufacturers sometimes use the letters ZR. For
those with a maximum speed capability over 186 mph (299 km/h), tire
manufacturers always use the letters ZR.
8.U.S. DOT Tire Identification Number (TIN):This begins with the
letters“DOT”and indicates that the tire meets all federal standards. The
next two numbers or letters are the plant code where it was
manufactured, the next two are the tire size code and the last four
numbers represent the week and year the tire was built. For example,
the numbers 317 mean the 31st week of 1997. After 2000 the numbers
go to four digits. For example, 2501 means the 25th week of 2001. The
numbers in between are identification codes used for traceability. This
information is used to contact customers if a tire defect requires a recall.
9.M+S or M/S:Mud and Snow. or
AT:All Terrain. or
AS:All Season.
10.Tire Ply Composition and Material Used:Indicates the number of
plies or the number of layers of rubber-coated fabric in the tire tread and
sidewall. Tire manufacturers also must indicate the ply materials in the
tire and the sidewall, which include steel, nylon, polyester, and others.
11.Maximum Load:Indicates the maximum load in kilograms and
pounds that can be carried by the tire. Refer to the tire label or the
safety certification label, located on the B-Pillar or the driver’s door, for
the correct tire pressure for your vehicle
12.Treadwear, Traction and Temperature Grades
•Treadwear:The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1
1⁄2) times as well on the government
course as a tire graded 100.
•Traction:The traction grades, from highest to lowest are AA, A, B,
and C. The grades represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.
