2008 LINCOLN NAVIGATOR sensor

When mounting replacement tires and wheels, you should not
exceed the maximum pressure indicated on the sidewall of the
tire to set the beads without additional precautions listed below. If the
beads do not seat at the maximum pressure indicated, re-lubricate and
try again.
When inflating the tire for mounting pressures up to 20 psi greater
than the maximum pressure on the tire sidewall, the following
precautions must be taken to protect the person mounting the tire:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and wheel bead seat area again.
3. Stand at a minimum of 12 feet away from the tire wheel assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20 psi greater than the maximum
pressure, a Ford Dealer or other tire service professional should do the
mounting.
Always inflate steel carcass tires with a remote air fill with the person
inflating standing at a minimum of 12 ft. away from the tire wheel
assembly.
Important:Remember to replace the wheel valve stems when the road
tires are replaced on your vehicle.
It is recommended that the two front tires or two rear tires generally be
replaced as a pair.
The tire pressure sensors mounted in the wheels (originally installed on
your vehicle) are not designed to be used in aftermarket wheels.
The use of wheels or tires not recommended by Ford Motor Company
may affect the operation of your Tire Pressure Monitoring System.
If the TPMS indicator is flashing, your TPMS is malfunctioning. Your
replacement tire might be incompatible with your TPMS, or some
component of the TPMS may be damaged.
Safety practices
Driving habits have a great deal to do with your tire mileage and safety.
•Observe posted speed limits
•Avoid fast starts, stops and turns
•Avoid potholes and objects on the road
•Do not run over curbs or hit the tire against a curb when parking

following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
The Tire Pressure Monitoring System is NOT a substitute for
manually checking tire pressure. The tire pressure should be
checked periodically (at least monthly) using a tire gauge, see
Inflating your tiresin this chapter. Failure to properly maintain your
tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
Changing tires with TPMS
Each road tire is equipped with
a tire pressure sensor fastened
to the inside rim of the wheel.
The pressure sensor is covered
by the tire and is not visible
unless the tire is removed. The
pressure sensor is located
opposite (180 degrees) from the
valve stem. Care must be taken
when changing the tire to avoid
damaging the sensor.It is
recommended that you always have
your tires serviced by an authorized
dealer.
The tire pressure should be checked
periodically (at least monthly) using
an accurate tire gauge, refer to
Inflating your tiresin this chapter.
Understanding your Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System measures pressure in your four
road tires and sends the tire pressure readings to your vehicle. The Low
Tire Pressure Warning Lamp will turn ON if the tire pressure is
significantly low. Once the light is illuminated, your tires are under
inflated and need to be inflated to the manufacturer’s recommended tire
pressure. Even if the light turns ON and a short time later turns OFF,
your tire pressure still needs to be checked.

If the vehicle is above 25 mph (40 km/h), momentarily pressing the
AdvanceTrac
with RSC button will steadily illuminate the “sliding car”
icon
, however, the AdvanceTrac
with RSC system will remain
enabled until the vehicle speed drops below 25 mph. If the vehicle speed
decreases below 25 mph (40 km/h), the system will become deactivated,
but if the vehicle speed subsequently increases to above 25 mph
(40 km/h), the system will again become active. In general, the system
will be active at all times the vehicle speed is above 25 mph (40 km/h).
In R (Reverse), ABS and the Traction Control feature will continue to
function, however ESC and RSC are disabled.
All these conditions are normal during AdvanceTrac
with RSC
operation. Refer to the following table.

Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac
with RSC system. Also, do not install a stereo
loudspeaker near the front center console or tunnel or under either
front seat as the vibrations can adversely affect the AdvanceTrac
with
RSC sensors located in this area.

The reverse sensing system is automatically enabled when the gear
selector is placed in R (Reverse) and the ignition is ON. A control in the
message center allows the driver to disable the system only when the
ignition is ON and the gear selector is in R (Reverse). Refer toMessage
centerin theDriver Controlschapter.
The message center will indicate the system is OFF and will not allow
the driver to switch the system ON to indicate a failure of the reverse
sensing system.
The radar sensor is located behind the rear bumper/fascia. Always
keep the rear bumper/fascia free from snow, ice and large
accumulations of dirt. These elements may cause the system to
operate inaccurately.
If the vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensors, refer toTire Pressure Monitoring System
(TPMS)in theTires, Wheels and Loadingchapter. Replace the spare
tire with a road tire as soon as possible.
The use of tire sealants may damage your Tire Pressure
Monitoring System and should not be used.
Refer toTire Pressure Monitoring System (TPMS)in theTires,
Wheels and Loadingchapter for important information. If the tire
pressure monitor sensor becomes damaged, it will no longer function.
Dissimilar spare tire/wheel information
Failure to follow these guidelines could result in an increased
risk of loss of vehicle control, injury or death.
If you have a dissimilar spare tire/wheel, then it is intended for
temporary use only. This means that if you need to use it, you should
replace it as soon as possible with a road tire/wheel that is the same size
and type as the road tires and wheels that were originally provided by
Ford. If the dissimilar spare tire or wheel is damaged, it should be
replaced rather than repaired.

Changing the air filter element
1. Locate the Mass Air Flow Sensor
electrical connector on the air outlet
tube. This connector will need to be
unplugged.
2. Reposition the locking clip on the
connector (connector shown from
below for clarity), squeeze the
connector and pull it off of the air
outlet tube.
3. Clean the area around the air
tube to air cover connection to
prevent debris from entering the
system and then loosen the bolt on
the air tube clamp so the clamp is
no longer snug to the air tube. It is
not necessary to completely remove
the clamp.
4. Pull the air tube off from the air
cleaner housing.

Note:Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
