GASOLINE
WARNING: Batteries normally
produce explosive gases which can cause
personal injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation.
WARNING: When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in personal
injury and damage to the vehicle or battery.
Lift the battery with a battery carrier or with
your hands on opposite corners.
WARNING: Keep batteries out of
reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or
clothing. Shield your eyes when working
near the battery to protect against possible
splashing of acid solution. In case of acid
contact with skin or eyes, flush immediately
with water for a minimum of 15 minutes and
get prompt medical attention. If acid is
swallowed, call a physician immediately.
WARNING: Battery posts, terminals
and related accessories contain lead and
lead compounds, chemicals known to the
State of California to cause cancer and
reproductive harm. Wash your hands after
handling.
WARNING: This vehicle may have
more than one battery. Removing the
battery cables from only one battery does
not disconnect your vehicle electrical
system. Make sure you disconnect the
battery cables from all batteries when
disconnecting power. Failure to do so may
cause serious personal injury or property
damage.
WARNING: For vehicles with
Auto-Start-Stop the battery requirement is
different. You must replace the battery with
one of exactly the same specification.
The battery is in the engine compartment.
See Under Hood Overview (page 400).
Your vehicle has a maintenance-free battery.
It does not require additional water during
service.
If the vehicle battery has a cover and vent
hose, make sure you correctly install it after
cleaning or replacing the battery.

Maintenance

For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the battery
terminals. If any corrosion is present on the
battery or terminals, remove the cables from
the terminals and clean with a wire brush.
You can neutralize the acid with a solution
of baking soda and water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note:If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.
If you replace the battery make sure it
matches the electrical requirements of your
vehicle.If you disconnect or replace the battery and
your vehicle has an automatic transmission,
it must relearn its adaptive strategy. Because
of this, the transmission may shift firmly when
first driven. This is normal operation while
the transmission fully updates its operation
to optimum shift feel.
Battery Sensor Reset
When you install a new battery, reset the
battery sensor by doing the following:
1. Switch the ignition on, and leave the
engine off.
Note:Complete Steps 2 and 3 within 10
seconds.
2. Flash the high beam headlamps five
times, ending with the high beams off.
3. Press and release the brake pedal three
times.
The battery warning lamp flashes three times
to confirm that the reset is successful.
Battery Management System (If Equipped)
The system monitors battery conditions and
takes actions to extend battery life. If
excessive battery drain is detected, the
system temporarily disables some electrical
systems to protect the battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
display to alert you that battery protection

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 460).

Maintenance

Note: Do not use razor blades or other
sharp objects to clean or remove decals from
the inside of the heated rear window. The
vehicle warranty does not cover damage
caused to the heated rear window grid lines.
CLEANING THE INTERIOR
WARNING: Do not use cleaning
solvents, bleach or dye on the vehicle's
seatbelts, as these actions may weaken
the belt webbing.
WARNING: On vehicles equipped
with seat-mounted airbags, do not use
chemical solvents or strong detergents.
Such products could contaminate the side
airbag system and affect performance of
the side airbag in a crash.For fabric, carpets, cloth seats and seats
equipped with side airbags:
• Remove dust and loose dirt with a
vacuum cleaner.
• Remove light stains and soil with
Motorcraft Professional Strength Carpet
& Upholstery Cleaner.
• If grease or tar is present on the material,
spot-clean the area first with Motorcraft
Spot and Stain Remover. In Canada, use
Motorcraft Multi-Purpose Cleaner.
• If a ring forms on the fabric after spot
cleaning, clean the entire area
immediately (but do not oversaturate) or
the ring will set.
• Do not use household cleaning products
or glass cleaners, which can stain and
discolor the fabric and affect the flame
retardant abilities of the seat materials.
Mirrors
Do not clean the housing or glass of any
mirror with harsh abrasives, fuel or other
petroleum or ammonia-based cleaning
products.
CLEANING THE INSTRUMENT
PANEL AND INSTRUMENT
CLUSTER LENS
WARNING: Do not use chemical
solvents or strong detergents when
cleaning the steering wheel or instrument
panel to avoid contamination of the airbag
system.
Note:Follow the same procedure as
cleaning leather seats for cleaning leather
instrument panels and leather interior trim
surfaces. See Cleaning Leather Seats (page
426).
Clean the instrument panel and cluster lens
with a clean, damp and soft cloth, then use
a clean, dry and soft cloth to dry these areas.

Vehicle Care

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 432).
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.
430
Wheels and Tires

Study your owner's manual and any
supplements for specific information about
equipment features, instructions for safe
driving and additional precautions to reduce
the risk of an accident or serious injury.
All-wheel drive system (if equipped)
WARNING: Do not become
overconfident in the ability of all-wheel
drive vehicles. Although an all-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed.A vehicle equipped with all-wheel drive has
the ability to use all four wheels to power
itself. This increases traction which may
enable you to safely drive over terrain and
road conditions that a conventional
two-wheel drive vehicle cannot. Power is
supplied to all four wheels through a transfer
case operation and drive mode selection.
See All-Wheel Drive (page 264). You should
become thoroughly familiar with this
information before you operate your vehicle.
Some limited All Wheel Drive (AWD) traction
may be provided if a temporary spare is
installed on one of the front wheels. If you
are in driving conditions where limited All
Wheel Drive (AWD) traction needed while a
temporary wheel is installed, it is
recommended the temporary spare be
installed on the front axle.
For all-wheel-drive vehicles, a spare tire of
a different size other than the tire provided
should never be used. A dissimilar spare tire
size; other than the spare tire provided or
major dissimilar tire sized between the front
and rear axles could cause the
all-wheel-drive system to stop functioning
and default to rear-wheel drive.
How your vehicle differs from other
vehicles
Sport utility vehicles and trucks can differ
from some other vehicles in a few noticeable
ways. Your vehicle could be:
• Higher - to allow higher load carrying
capacity and to allow it to travel over
rough terrain without getting hung up or
damaging underbody components.
• Shorter - to give it the capability to
approach inclines and drive over the
crest of a hill without getting hung up or
damaging underbody components. All
other things held equal, a shorter
wheelbase could make your vehicle
quicker to respond to steering inputs
than a vehicle with a longer wheelbase.
• Narrower - to provide greater
maneuverability in tight spaces,
particularly in off-road use.
431
Wheels and Tires

As a result of the above dimensional
differences, sport utility vehicles and trucks
often 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
E142542
Tire Quality Grades apply to new
pneumatic passenger car tires. The
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 us to give you
the following information about tire
grades exactly as the government has
written it.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 1½ times as well on the
government course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction AA A B C
WARNING: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning or peak
traction characteristics.
432
Wheels and Tires

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.
Temperature A B C
WARNING: The temperature
grade for this tire is established for a
tire that is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.
The temperature grades are A (the
highest), B and C, representing the tire’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can causethe material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 139. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
Glossary of Tire Terminology
*Tire label: A label showing the original
equipment tire sizes, recommended
inflation pressure and the maximum
weight the vehicle can carry.
*Tire Identification Number (TIN): A
number on the sidewall of each tire
providing information about the tire
brand and manufacturing plant, tire size
and date of manufacture. Also referred
to as DOT code.
*Inflation pressure: A measure of the
amount of air in a tire.*Standard load: A class of P-metric or
Metric tires designed to carry a
maximum load at set pressure. For
example: For P-metric tires 35 psi
(2.4 bar) and for Metric tires 36 psi
(2.5 bar). Increasing the inflation
pressure beyond this pressure will not
increase the tire’s load carrying
capability.
*Extra load: A class of P-metric or Metric
tires designed to carry a heavier
maximum load at 42 psi (2.9 bar).
Increasing the inflation pressure beyond
this pressure will not increase the tire’s
load carrying capability.
*kPa: Kilopascal, a metric unit of air
pressure.
*PSI: Pounds per square inch, a standard
unit of air pressure.
*Cold tire pressure: The tire pressure
when the vehicle has been stationary
and out of direct sunlight for an hour or
more and prior to the vehicle being
driven for 1 mi (1.6 km).
