2006 FORD EXPLORER TPMS

How temperature affects your tire pressure
The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. The pressure in each tire is dependent upon several
factors, one of them being the contained air temperature (temperature of
the air inside the tire). As the contained air temperature increases, the
tire pressure also increases. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. This increase in tire pressure
is due to an increase in the contained air temperature. Contained air
temperature is dependent upon several factors such as rate of tire
rotation, tire deflection, amount of braking, etc. In a similar manner, the
tire pressure will decrease if the contained air temperature decreases.
For example, if the vehicle is stationary over night with the outside
temperature significantly lower than the daytime temperature, the tire
pressure may decrease approximately 3 psi (20.7 kPa) for a drop of 30É
F (16.6É C) in ambient temperature. This lower pressure value may be
detected by the TPMS as being significantly lower than the cold pressure
indicated on your vehicles Safety Compliance Certification Label, and
activate the TPMS warning for low tire pressure. If the low tire pressure
warning light is ON, visually check each tire to verify that no tire is flat.
If one or more tires are flat, repair as necessary. Check air pressure in
the road tires. If any tire is underinflated, carefully drive the vehicle to
the nearest location where air can be added to the tires. Turn the
ignition to the OFF position. Inflate all the tires to the recommended
inflation pressure.
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 an accurate tire gauge,
seeInspecting and 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.
Tires, Wheels and Loading
191

leave the vehicle unattended with the transfer case in the N (Neutral)
position. Always set the parking brake fully and turn off the ignition
when leaving the vehicle.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
4WD Systems
4WD uses all four wheels to power the vehicle. This increases traction,
enabling you to drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels
through a transfer case. On 4WD
vehicles, the transfer case allows
you to select 4WD when necessary.
Information on transfer case
operation and shifting procedures
can be found in theDriving
chapter. Information on transfer
case maintenance can be found in theMaintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
Normal characteristics
On some 4WD models, the initial shift from two-wheel drive to 4x4 while
the vehicle is moving can cause some momentary clunk and ratcheting
sounds. This is the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not cause for concern.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Note:If your vehicle is equipped with the Tire Pressure Monitoring
System (TPMS), the system indicator light may illuminate depending on

CHANGING THE TIRES
If you get a flat tire while driving:
²do not brake heavily.
²gradually decrease the vehicle's speed.
²hold the steering wheel firmly.
²slowly 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 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.
Roadside Emergencies
246

Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensor, refer toChanging tires with TPMSin theTires,
Wheels and Loadingchapter. Replace the spare tire with a road tire as
soon as possible.
The use of tire sealants may damage your tires. The use of tire
sealants may also damage your Tire Pressure Monitoring System
and should not be used.
Refer toTire Pressure Monitoring System (TPMS)in the
Tires, 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.
A dissimilar spare tire/wheel is defined as a spare tire and/or wheel that
is different in brand, size or appearance from the road tires and wheels
and can be one of three types:
1.T-type mini-spare:This spare tire begins with the letter ªTº for tire
size and may have ªTemporary Use Onlyº molded in the sidewall
2.Full-size dissimilar spare with label on wheel:This spare tire has
a label on the wheel that states: ªTHIS TIRE AND WHEEL FOR
TEMPORARY USE ONLYº
When driving with one of the dissimilar spare tires listed above,do not:
²Exceed 50 mph (80 km/h)
²Load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
²Tow a trailer
Roadside Emergencies
247

When driving with the full-size dissimilar spare tire/wheel additional
caution should be given to:
²Towing a trailer
²Driving vehicles equipped with a camper body
²Driving vehicles with a load on the cargo rack
Drive cautiously when using a full-size dissimilar spare tire/wheel and
seek service as soon as possible.
Stopping and securing the vehicle
1. 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.
2. Park on a level surface, activate
the hazard flashers and set the
parking brake.
3. Place gearshift lever in P (Park)
and turn engine OFF.
When one of the rear wheels is off the ground, the transmission
alone will not prevent the vehicle from moving or slipping off the
jack, even if the transmission is in P (Park).
Note:Passengers should not remain
in the vehicle when the vehicle is
being jacked.
4. Block the wheel that is diagonally
opposite of the flat tire using the
wheel chock provided with your
vehicle.
Location of the spare tire and tools
Note:If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the system indicator light will illuminate when the spare
is in use. To restore the full functionality of the TPMS system, all road
wheels equipped with the tire pressure monitoring sensors must be
mounted on the vehicle
Roadside Emergencies
249

If your vehicle is equipped with TPMS, have a flat tire serviced by an
authorized dealer in order to prevent damage to the TPMS sensor, refer
toChanging tires with TPMSin theTires, Wheels and Loading
chapter. Replace the spare tire with a road tire as soon as possible.
The spare tire and tools for your vehicle are stowed in the following
locations:
Tool Location
Spare tire Under the vehicle, just in front of
the rear bumper. The spare tire
winch drive nut is located at the
rear center of the cargo area
under a lid.
Jack, lug nut wrench, jack handle,
wheel chockBehind the rear seat under the
carpeted floor lid in the cargo
floor. The tools are located in a
bag attached to the jack.
Removing the jack and tools
1. Open liftgate and remove the
carpeted floor lid, then the jack.
2. Unscrew the wing bolt to detach
the tether from the jack.
3. Turn jack screw eyelet
counterclockwise and remove the
jack from the bracket.
4. Remove the tools from the
provided bag.
