REPORTING SAFETY DEFECTS
(U.S. ONLY)
If you believe that your vehicle has a
defect which could cause a crash or
could cause injury or death, you should
immediately inform the National
Highway Traffic Safety Administration
(NHTSA) in addition to notifying Ford
Motor Company.
If NHTSA receives similar complaints, it
may open an investigation, and if it finds
that a safety defect exists in a group of
vehicles, it may order a recall and
remedy campaign. However, NHTSA
cannot become involved in individual
problems between you, your dealer, or
Ford Motor Company.
To contact NHTSA, you may call the
Vehicle Safety Hotline toll-free at
1-888-327-4236 (TTY: 1-800-424-9153);
go to www .safercar . gov ; or write to:

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.
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. When changing the air filter element, use
only the air filter element listed.
See
Motorcraft Parts (page 439).
Change the air filter element at the correct
interval. See Scheduled Maintenance (page
543
). 1. Release the two clamps that secure the
cover to the air filter housing. Push the
air filter cover toward the front of the
vehicle and up slightly to release it.
2. Remove the air filter element from the air
filter housing.
3. Install the new air filter element.

Navigator (TB9) Canada/United States of America, enUSA, First-Printing MaintenanceE248801

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
ensure that you properly align the tabs
on the edge into the slots. ENGINE COOLANT CHECK 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 put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield. WARNING:
To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system is
under pressure. Steam and hot liquid can
come out forcefully when you loosen the
cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
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 539).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
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.

Follow these guidelines when using snow
tires and chains:
•
If possible, avoid fully loading your
vehicle.
• Use only cable type chains or chains
offered by Ford/Lincoln as an accessory
or equivalent. Other conventional link
type chains may contact and cause
damage to the vehicle's wheel house
and/or body.
• Do not install chains on the front tires as
this may interfere with suspension
components.
• Only certain snow cables or chains have
been approved by Ford/Lincoln as safe
for use on your vehicle with the following
tires: 265/70R17 and 275/65R18.
• You should install snow cables or chains
that have been rated as SAE Class S.
• Install chains securely, verifying that the
chains do not touch any wiring, brake
lines, or fuel lines.
• Do not exceed 31 mph (50 km/h) or less
if recommended by the chain
manufacturer while using snow chains. •
Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does not
work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when they are no
longer needed. Do not use tire chains on
dry roads.
• Purchase chains or cables from a
manufacturer that clearly labels body to
tire dimension restrictions. The snow
chains or cables must be mounted in
pairs on the rear tires only.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer. 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 could cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it will not
function.

Tire Change Procedure WARNING: Only use replacement
tires and wheels that are the same size,
load index, speed rating and type (such as
P-metric versus LT-metric or all-season
versus all-terrain) as those originally
provided by Ford. The recommended tire
and wheel size may be found on either 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), or the Tire Label
which is located on the B-Pillar or edge of
the driver's door. If this information is not
found on these labels, then you should
contact your authorized dealer as soon as possible. Use of any tire or wheel not
recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk of
loss of vehicle control, vehicle rollover,
personal injury and death.
WARNING:
To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park (P),
set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel, place
an appropriate block or wheel chock on
the right rear wheel. WARNING: Do not attempt to change
a tire on the side of the vehicle close to
moving traffic. Pull far enough off the road
to avoid the danger of being hit when
operating the jack or changing the wheel. WARNING: Always use the jack
provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. If you
are unsure if the jack capacity is adequate,
contact the authorized dealer.

WARNING: Switch off the running
boards before jacking or placing any object
under your vehicle. Never place your hand
between the extended running board and
your vehicle. A moving running board may
cause injury. WARNING: Only use the spare wheel
carrier to stow the wheel provided with
your vehicle. Other wheel sizes could
cause the spare wheel carrier to fail if it
does not fit securely or is too heavy. 1.
Park the vehicle on firm, level ground and
activate the hazard flashers. 2. Apply the parking brake, place the
transmission in park (P) and switch the
ignition off.
3. Block the wheels diagonally opposite the
flat tire, for example, if the left front tire
is flat, block the right rear wheel.
Removing the Jack and Tools
Note: Pay close attention to the orientation
of the jack and tool kit bag, because it needs
to be reinstalled after changing the tire.
1. Open the liftgate and lift the load floor behind the third row seat. If your vehicle
has an access panel, you need to then
unlatch and remove this panel.
2. Remove the wing nut by turning it counterclockwise.
3. Remove the jack and tool kit bag from the bracket, loosen the straps and
remove the tool bag from the jack. Removing the Spare Tire
1.
Remove the swivel wrench from the tool
kit bag, open the spare tire winch access
plug at the bottom of the compartment
for the jack and tools tray.
2. Insert the swivel wrench through the access hole in the floor to engage the
winch. Turn the handle counterclockwise
until the tire lowers to the ground and
the cable is slightly slack.

and secure with the wing nut. 8. Close the access hole with the rubber
plug. 9. If the vehicle has an access panel,
reinstall.
10. Unblock the wheel.
TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications WARNING: When you install a wheel, always remove any corrosion, dirt or foreign m\
aterials present on the mounting surfaces of the
wheel or the surface of the wheel hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners that attach
the rotor to the hub so they do not interfere with the mounting surfaces\
of the wheel. Installing wheels without correct metal-to-metal contact
at the wheel mounting surfaces can cause the wheel nuts to loosen and th\
e wheel to come off while your vehicle is in motion, resulting in
loss of vehicle control, personal injury or death. lb.ft (Nm)
