Note:
If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km).
Adding Engine Oil WARNING:
Do not remove the filler
cap when the engine is running.
Do not use supplemental engine oil additives
because they are unnecessary and could
lead to engine damage that may not be
covered by the vehicle Warranty. Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol conforms
to the current engine and emission system
protection standards and fuel economy
requirements of the International Lubricants
Specification Advisory Committee (ILSAC).
To top up the engine oil level do the
following:
1. Clean the area surrounding the engine
oil filler cap before you remove it.
2. Remove the engine oil filler cap.
See
Under Hood Overview (page 386). Turn
it counterclockwise and remove it. 3. Add engine oil that meets our
specifications.
See Capacities and
Specifications (page 450). You may have
to use a funnel to pour the engine oil into
the opening.
4. Recheck the oil level.
5. If the oil level is correct, replace the dipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately.
OIL CHANGE INDICATOR RESET

Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection. Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
450).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display.If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.

When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for use
during emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in
a safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will
have limited power, will not be able to
maintain high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury. Your vehicle has limited engine power when
in the fail-safe mode, drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine may
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend that
you contact your roadside assistance
service provider.
3. If this is not possible, wait for a short period of time for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage. Engine Coolant Temperature
Management
(If Equipped) WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the vehicle
may not be able to accelerate with full
power until the coolant temperature
reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.

WARNING: Only use brake fluid from
a sealed container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death. WARNING:
Do not allow the fluid to
touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician. WARNING:
The brake system could
be affected if the brake fluid level is below
the
MIN mark or above the MAX mark on
the brake fluid reservoir. 1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative to
the
MIN and the MAX marks on the
reservoir.
Note: If the brake fluid level is between the
MIN
and the MAX marks on the reservoir, it
is acceptable. Note:
If the brake fluid level is below the MIN
mark or above the
MAX mark, have your
vehicle checked as soon as possible.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our specifications.
See
Capacities and Specifications (page
450).
Brake Fluid Service Interval
Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Change the brake fluid at the specified
intervals to prevent degraded braking
performance.
For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide.
POWER STEERING FLUID CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.

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 Management System (If Equipped)
The battery management 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
displays to alert you that battery protection
actions are active. These messages are only
for notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
After battery replacement, or in some cases
after charging the battery with an external
charger, the battery management system
requires eight hours of vehicle sleep time to
relearn the battery state of charge. During
this time your vehicle must remain fully
locked with the ignition switched off.
Note:
Prior to relearning the battery state of
charge, the battery management system
may temporarily disable some electrical
systems.

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
409).
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.

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.
The tires installed on your vehicle from us
as original equipment are certified for
Greenhouse Gas and Fuel Efficiency
regulations. Replacement tires must be of
equal or lower rolling resistance level (TRRL
or CRR). Consult with your tire supplier for
appropriate replacement tires.
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 415).
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.
