screwdriver or socket wrench, to turn the
adjuster clockwise or counterclockwise
to adjust the vertical aim of the
headlamp. The horizontal edge of the
brighter light should touch the horizontal
reference line.
6. Close the hood and switch off the lamps.
WASHER FLUID CHECK WARNING: If you operate your
vehicle in temperatures below 41.0°F (5°C),
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: The front and rear washer systems
are supplied from the same reservoir.
Add fluid to fill the reservoir if the level is low.
Only use a washer fluid that meets our
specifications.
See Capacities and
Specifications (page 421). 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.

REPAIRING MINOR PAINT
DAMAGE
Authorized dealers have touch-up paint to
match your vehicle
’s color. Your vehicle
color code is printed on a sticker on the front,
left-hand side door jamb. Take your color
code to your authorized dealer to make sure
you get the correct color.
Before repairing minor paint damage, use a
cleaner such as Motorcraft Bug and Tar
Remover to remove particles such as bird
droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout.
Read the instructions before using cleaning
products.
CLEANING THE WHEELS
1. Regularly clean them with a wheel cleaner. We recommend that you use
Ford approved wheel cleaner if available.
2. Remove dirt and brake dust with a sponge. 3. Remove tar and grease with a bug and
tar remover. We recommend that you use
Ford approved bug and tar remover if
available.
4. Thoroughly rinse the wheels with water after cleaning.
If you intend on parking your vehicle for an
extended period after cleaning the wheels
with a wheel cleaner, drive your vehicle for
a few minutes before doing so. This reduces
the risk of corrosion of the brake discs, brake
pads and linings.
Do not clean the wheels when they are hot.
Note: Some car washes could damage
wheel rims and covers.
Note: Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers. VEHICLE STORAGE
If you plan on storing your vehicle for 30
days or more, read the following
maintenance recommendations to make sure
your vehicle stays in good operating
condition.
We engineer and test all motor vehicles and
their components for reliable, regular driving.
Under various conditions, long-term storage
may lead to degraded engine performance
or failure unless you use specific precautions
to preserve engine components.
General
•
Store all vehicles in a dry, ventilated
place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and damage.

GENERAL INFORMATION
The recommended tire inflation pressures
are found on the Tire Label which is located
on the B-pillar or the edge of the driver door.
This information can also be found on the
Safety Compliance Certification Label, affixed
to either the door hinge pillar, door-latch
post, or the door edge that meets the
door-latch post; next to the driver’
s seating
position.
We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the way
your vehicle handles.
Note: Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least once
per month.
If your vehicle has a spare tire, set the
pressure to the highest value given for your
vehicle and tire size combination. Use only approved wheels and tire sizes,
using other sizes could damage your vehicle.
If you change the diameter of the factory
installed tires, the speedometer may not
display the correct speed. This could effect
the functionality of the All Wheel Drive (AWD)
system, if equipped. Take your vehicle to an
authorized dealer and have the engine
management system reprogrammed.
If you intend to change the size of the factory
installed tires, check the suitability with an
authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found in the Wheels and Tire section.
See Tire Care (page 389).
Notice to utility vehicle and truck
owners WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seatbelt.
Utility vehicles and trucks handle differently
than passenger cars in the various driving
conditions that are encountered on streets,
highways and off-road. Utility vehicles and
trucks are not designed for cornering at
speeds as high as passenger cars any more
than low-slung sports cars are designed to
perform satisfactorily under off-road
conditions.

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 one
sixteenth of an inch (2 mm), 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
one sixteenth of an inch (2 mm).
When the tire tread wears down to the
same height as these wear bars, the tire
is worn out and must be replaced.Damage
Periodically inspect the tire treads and
sidewalls for damage (such as bulges in
the tread or sidewalls, cracks in the
tread groove and separation in the tread
or sidewall). If damage is observed or
suspected, have the tire inspected by a
tire professional. Tires can be damaged
during off-road use, so inspection after
off-road use is also recommended.
Age
WARNING: Tires degrade over
time depending on many factors such
as weather, storage conditions, and
conditions of use (load, speed, inflation
pressure) the tires experience
throughout their lives.

Tire Rotation
WARNING: If the tire label shows
different tire pressures for the front
and rear tires and the vehicle has a
tire pressure monitoring system, then
you need to update the settings for
the system sensors. Always perform
the system reset procedure after tire
rotation. If you do not reset the system,
it may not provide a low tire pressure
warning when necessary.
Note: If your tires show uneven wear,
ask an authorized dealer to check for
and correct any wheel misalignment,
tire imbalance or mechanical problem
involved before tire rotation. Note:
Your vehicle may be equipped
with a dissimilar spare wheel and tire
assembly. A dissimilar spare wheel and
tire assembly is defined as a spare
wheel and tire assembly that is different
in brand, size or appearance from the
road tires and wheels. If you have a
dissimilar spare wheel and tire
assembly, it is intended for temporary
use only and should not be used in a
tire rotation.
Note: After having your tires rotated,
inflation pressure must be checked and
adjusted to the vehicle requirements.
Rotating your tires at the recommended
interval will help your tires wear more
evenly, providing better tire performance
and longer tire life. Sometimes irregular
tire wear can be corrected by rotating
the tires.
See Scheduled Maintenance
(page 522).

vehicles, front tires at left of diagram. USING SUMMER TIRES
Summer tires provide superior performance
on wet and dry roads. Summer tires do not
have the Mud and Snow (M+S or M/S) tire
traction rating on the tire side wall. Since
summer tires do not have the same traction
performance as All-season or Snow tires, we
do not recommend using summer tires when
temperatures drop to approximately 45°F
(7°C) or below (depending on tire wear and
environmental conditions) or in snow and ice

TIRE PRESSURE MONITORING
SYSTEM
WARNING: The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to correctly
maintain tire pressures could increase the
risk of tire failure, loss of control, vehicle
rollover and personal injury.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it may not
function. Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle
has tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should
determine the proper tire inflation pressure
for those tires).
As an added safety feature, your vehicle has
been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates a
low tire pressure telltale when one or more
of your tires is significantly under-inflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle ’s handling and stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’
s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from
