If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
•A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
corrosion/freeze protection characteristics of the engine coolant and
may cause engine damage.
Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant for optimum cooling system and engine
protection.
What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The fail-safe distance depends on ambient temperatures, vehicle load and
terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine coolant temperature gauge
will move to the red (hot) area and:
The coolant temperature warning light will illuminate.
The service engine soon indicator will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to increase.
Once the engine temperature cools, the engine can be restarted. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.

5. Locate the vertical adjuster on
each headlamp, then use a Phillips
#2 screwdriver to turn the adjuster
either counterclockwise or
clockwise in order to adjust the
vertical aim of the headlamp. The
upper edge of the light pattern
should touch the horizontal
reference line.
6. HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS
NOT ADJUSTABLE.
7. Repeat Steps 3–5 for the other headlamp.
8. Close the hood and turn off the lamps.
CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
These are examples of acceptable condensation:
•Presence of thin mist (no streaks, drip marks or droplets).
•Fine mist covers less than 50% of the lens.
These are examples of unacceptable moisture (usually caused by a lamp
water leak):
•Water puddle inside the lamp.
•Large water droplets, drip marks or streaks present on the interior of
the lens.
Take your vehicle to a dealer for service if any of the above conditions of
unacceptable moisture are present.

Note:Some spare tires operate at a higher inflation pressure than the
other tires. For T-type mini-spare tires, see theDissimilar Spare Tire
and Wheel Assembly Informationsection. Store and maintain at 60 psi
(4.15 bar). For full-size and dissimilar spare tires, seeDissimilar Spare
Tire and Wheel Assembly InformationunderChanging a Road Wheel
in this chapter. Store and maintain at the higher of the front and rear
inflation pressure as shown on the Tire Label.
6. Visually inspect the tires to make sure there are no nails or other
objects embedded that could poke a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel Valve Stems
Periodically inspect the tire treads for uneven or excessive wear and
remove objects such as stones, nails or glass that may be wedged in the
tread grooves. Check the tire and valve stems for holes, cracks, or cuts
that may permit air leakage and repair or replace the tire and replace
the valve stem. Inspect the tire sidewalls for cracking, cuts, bruises and
other signs of damage or excessive wear. If internal damage to the tire is
suspected, have the tire demounted and inspected in case it needs to be
repaired or replaced. For your safety, tires that are damaged or show
signs of excessive wear should not be used because they are more likely
to blow out or fail.
Improper or inadequate vehicle maintenance can cause tires to wear
abnormally. Inspect all your tires, including the spare, frequently, and
replace them if one or more of the following conditions exist:
Tire Wear
When the tread is worn down to
1/16th of an inch (2 millimeters),
tires must be replaced to help
prevent your vehicle from skidding
and hydroplaning. Built-in treadwear
indicators, or wear bars, which look
like narrow strips of smooth rubber
across the tread will appear on the
tire when the tread is worn down to
1/16th of an inch (2 millimeters).
When the tire tread wears down to the same height as these wear bars,
the tire is worn out and must be replaced.

4Do not use API S category oils labeled as SN, SM,SL or lower category unless the label also
displays the API certification mark. These oils do not meet all of the requirements of your
vehicles engine and emission system.5Do not use supplemental engine oil additives in your engine. They are unnecessary and could
lead to engine damage that is not covered by your Ford warranty.6Automatic transmissions that require MERCON™ LV should only use MERCON LV fluid. Refer
toscheduled maintenance informationto determine the correct service interval. Use of any
fluid other than the recommended fluid may cause transmission damage.7Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size
and if equipped with an in-tank cooler.8Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is considered lubricated
for life. These lubricants are not to be checked or changed unless a leak is suspected, service is
required or the axle has been submerged in water. The axle lubricant should be changed any
time the axle has been submerged in water.9Warning:The air conditioning refrigerant system contains refrigerant R–134a under high
pressure. Opening and air conditioning refrigerant system can cause personal injury. Only
qualified personnel should service the air conditioning refrigerant system.

When using SYNC:
•Do not operate playing devices if the power cords or cables are
broken, split or damaged. Place cords and cables out of the way,
so they do not interfere with the operation of pedals, seats,
compartments or safe driving abilities.
•Do not leave playing devices in your vehicle during extreme conditions
as it could cause them damage. See your device’s manual for further
information.
•Do not attempt to service or repair the system. See your authorized
dealer.
For your safety, some SYNC functions are speed-dependent. Their use is
limited to when your vehicle is traveling at speeds under 3 mph (5 km/h).
Make sure that you review your device’s manual before using it with
SYNC.
Privacy Information
When a cellular phone is connected to SYNC, the system creates a
profile within your vehicle that is linked to that cellular phone. This
profile is created in order to offer you more cellular features and to
operate more efficiently. Among other things, this profile may contain
data about your cellular phone book, text messages (read and unread),
and call history, including history of calls when your cell phone was not
connected to the system. In addition, if you connect a media device,
the system creates and retains an index of supported media content.
The system also records a short development log of approximately
10 minutes of all recent system activity. The log profile and other system
data may be used to improve the system and help diagnose any problems
that may occur.
The cellular profile, media device index, and development log remain in
the vehicle unless you delete them and are generally accessible only in
the vehicle when the cellular phone or media player is connected. If you
no longer plan to use the system or the vehicle, we recommend you
perform a Master Reset to erase all stored information.
