2009 LINCOLN NAVIGATOR suspension

Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

Removing the spare tire
1. Remove the jack handle and
winch extension from the tray and
assemble them.
2. Open the spare tire winch access
plug in the bottom of the
compartment for the jack and tools
tray.
3. Insert the winch extension tool
assembly through the access hole in
the floor and engage the winch.
4. To remove the spare tire, turn the
handle counterclockwise until the
tire is lowered to the ground and
the cable is slightly slack.
5. Slide the retainer through the center of the spare tire wheel.
Tire change procedure
WARNING:To help prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block the
wheels (both front or both rear) on the opposite end of the vehicle
from the wheel being changed. If on a grade, block both opposite
wheels on the downward side of the hill.
WARNING:If the vehicle slips off the jack, you or someone else
could be seriously injured.
WARNING:On vehicles equipped with air suspension, turn off
the air suspension system prior to jacking, hoisting or towing
your vehicle.
WARNING:Turn off the running boards (if equipped) before
jacking or placing any object under the vehicle. Never place your
hand between the extended running board and the vehicle. A moving
running board may cause injury.

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 and changing the
wheel.
If your vehicle is equipped with air suspension, refer toMessage center
in theDriver Controlschapter for instructions on turning the air
suspension system off.
Refer to the instruction sheet (located in the rear floor compartment
behind the 3rd row seat with the jack tray tools assembly kit) for
detailed tire change instructions.
1. Block the wheels (both front or
both rear) on the opposite end of
the vehicle from the wheel being
changed. If on a grade, block both
wheels on the downward side of the
hill.
2. Turn off the air suspension system. The air suspension system is
controlled through the message center. Refer toAir suspension system
in theDrivingsection for more information. Also, turn off the
deployable running boards (if equipped). SeeMessage centerin the
Driver controlssection.
3. Obtain the spare tire and jack from their storage locations.
4. Use the tip of the jack handle to
remove any wheel trim. Loosen each
wheel lug nut one-half turn
counterclockwise but do not remove
them until the wheel is raised off
the ground.

WARNING:Turn off the running boards (if equipped) before
jacking or placing any object under the vehicle. Never place your
hand between the extended running board and the vehicle. A moving
running board may cause injury.
•Never use the front or rear
differential as a jacking point.
WARNING:To lessen the risk of personal injury, do not put any
part of your body under the vehicle while changing a tire. Do not
start the engine when your vehicle is on the jack. The jack is only
meant for changing the tire.
7. Remove the lug nuts with the lug wrench.

facing outward. Reinstall the lug nuts until the wheel is snug against the
hub. Do not fully tighten the lug nuts until the wheel has been lowered.
9. Lower the wheel by turning the jack handle counterclockwise.
10. Remove the jack and fully
tighten the lug nuts in the order
shown and reinstall the wheel cover.
11. Unblock the wheels.
12. Put flat tire, jack, lug wrench
and tools away. Make sure the jack
is fastened securely so it does not
rattle when you drive.

system (if equipped). Refer to
Message centerin theDriver Controlschapter for instructions on

WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
It is recommended that your vehicle be towed with a wheel lift or flatbed
equipment. Do not tow with a slingbelt. Ford Motor Company has not
approved a slingbelt towing procedure. Also, wrecker towing the vehicle
by the front frame-mounted tow hooks is not recommended or advised.
The air suspension control and the ignition must be turned off
before being towed. Refer toAir suspensionin theDriving
chapter.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground (without dollies) and the rear wheels off the ground.
On 4x4 vehicles, it is required that your vehicle be towed with a wheel
lift and dollies or flatbed equipment with all the wheels off the ground.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
