ENGINE OIL CAPACITY AND
SPECIFICATION

For filling information, please refer to the
Capacities and Specifications section of your
owner's manual. See Engine Oil Capacity
and Specification (page 471).

CHECKING THE COOLANT

When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information. See Scheduled Maintenance
(page 528).

Note: Make sure that the coolant level is
between the minimum and maximum marks
on the coolant reservoir.

Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.

If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.

Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -29°F (-34°C) and -35°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.

Adding Coolant

WARNING: Keep your hands and

clothing clear of the cooling fan.

418

Maintenance

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.

WARNING: Do not add engine

coolant when the engine is on or the
cooling system is hot. Failure to follow this
instruction could result in personal injury.

WARNING: Do not add coolant

further than the MAX mark.

WARNING: Do not put coolant in the

windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield.

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.

Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.

Note: Automotive fluids are not
interchangeable.

It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system. See Capacities
and Specifications (page 469). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and could void
the vehicle Warranty.

Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with deionized or distilled
water. See Capacities and Specifications
(page 469). Using water that has not been
deionized may contribute to deposit
formation, corrosion and plugging of the
small cooling system passageways.

To top up the coolant level do the following:

1. Unscrew the cap slowly. Any pressure

escapes as you unscrew the cap.

2. Add enough prediluted coolant to reach

the correct level.

Note: We do not recommend the use of
recycled coolant.

3. Replace the coolant reservoir cap. Turn

the cap clockwise until it contacts the
hard stop.

4. Check the coolant level in the coolant

reservoir the next few times you drive
your vehicle. If necessary, repeat step 2.

419

Maintenance

If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.

In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location.
Service your vehicle as soon as possible.

Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.

Do not use the following as a coolant
substitute, as they can cause engine damage
from overheating or freezing:
•

Alcohol.

•

Methanol.

•

Brine.

•

Any coolant mixed with alcohol or
methanol antifreeze.

Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant.

Severe Climates

If you drive in extremely cold climates, you
may need to increase the coolant
concentration above 50%.

Note: A coolant concentration of 60%
provides improved freeze point protection.
Coolant concentrations above 60% decrease
the overheat protection characteristics of
the coolant and could cause engine
damage.

If you drive in extremely hot climates, you
may need to decrease the coolant
concentration to 40%.

Note: A coolant concentration of 40%
provides improved overheat protection.
Coolant concentrations below 40% decrease
the overheat and corrosion protection
characteristics of the coolant and could
cause engine damage.

Coolant Change

WARNING: Do not dispose of coolant

in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.

Change the coolant at specific mileage
intervals. Refer to the scheduled
maintenance information. See Normal
Scheduled Maintenance (page 532).

Note: Dispose of used coolant in the
appropriate manner.

Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.

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.

420

Maintenance

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 could
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.

421

Maintenance

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.

You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to stop your vehicle. You can
continue to drive.

The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.

If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:

1. Stop your vehicle as soon as it is safe to

do so. Fully apply the parking brake, shift
into park (P) or neutral (N).

2. Leave the engine running until the

coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.

3. Switch the engine off and wait for it to

cool. Check the coolant level.

4. If the coolant level is at or below the

minimum mark, add prediluted coolant
immediately.

5. If the coolant level is normal, restart the

engine and continue.

ENGINE AIR FILTER

CHANGING THE ENGINE AIR FILTER

WARNING: To reduce the risk of

vehicle damage and personal burn injuries,
do not start your engine with the air
cleaner removed and do not remove it
while the engine is running.

422

Maintenance

Change the engine air filter element at the
proper intervals. See Normal Scheduled
Maintenance (page 532).

When changing the engine air filter, use only
the air filter element listed. See Motorcraft
Parts (page 470).

Note: Failure to use the correct air filter
element may result in severe engine
damage. Resulting component damage may
not be covered by the vehicle Warranty.

Note: When servicing the air cleaner, do not
allow foreign material to enter the air
induction system.

4. Replace the air filter housing cover and

secure all the clamps. Be careful not to
crimp the filter element edges between
the air filter housing and cover, and make
sure that you properly align the tabs on
the edge into the slots.

CHANGING THE FUEL FILTER

Your vehicle has a lifetime fuel filter that
integrates with the fuel tank. It does not need
regular maintenance or replacement.

CHANGING THE 12V BATTERY

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.
