2006 Mercury Mountaineer tires

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.
When replacing valve caps, use the same nylon valve caps that came
with your vehicle. Do not use chrome-plated valve caps because they
may corrode to the valve stems and damage the TPMS sensors.
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 every
minute while you are driving and once every 6 hours when your vehicle
is parked. The Low Tire Warning Lamp will turn ON if the tire pressure
is 25% below the pressure listed on the Safety Compliance Certification
Label (approximately 6 to 9 psi below the manufacturer’s recommend
tire pressure). If the tire pressure increases 2 psi above the “Light ON”
threshold, then the TPMS light will turn OFF. Once the light is
illuminated, your tires are underinflated 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.
In short, once the light has turned ON, at least one tire may be
underinflated.

When your temporary spare tire is installed (if equipped)
When one of your road tires needs to be replaced with the temporary
spare (T-type spare/Mini spare or Dissimilar spare), the TPMS system
will continue to identify an issue to remind you that the damaged road
wheel/tire needs to be repaired and put back on your vehicle. During this
time, the low tire warning light can periodically return or stay on,
depending on the state of the damaged road wheel/tire. This will include
messages from the message center (if equipped).
To restore the full functionality of the Tire Pressure Monitoring System,
have the damaged road wheel/tire repaired and remounted on your
vehicle. For additional information, refer toChanging tires with TPMS
in this section.
When you believe your system is not operating properly
The main function of the Tire Pressure Monitoring System is to warn you
when your tires need air. It can also warn you in the event the system is
no longer capable of functioning as intended. Please refer to the
following chart for information concerning your Tire Pressure Monitoring
System:

When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires. Here are the details:
•The tire pressure sensors mounted in your wheels updates your
vehicle with tire pressure information only once every minute,
therefore it may take up to two minutes of driving over 20 mph (32
km/h) for the light to turn OFF after you have filled your tires to the
recommended tire pressure.
•If your vehicle has been parked for over 30 minutes, the sensors go
into a low power mode to conserve battery life and therefore only
transmit about once every 6 hours. If you inflate your tires under
these conditions, it may take up to two minutes of driving over 20
mph (32 km/h) for the light to turn OFF after you have filled your
tires to the recommended tire pressure.
For these reasons, the low tire pressure warning light is NOT a
substitute for using an accurate tire gauge when checking and filling
your tires.

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 30°
F (16.6° 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,
seeInflating 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.

USING SNOW TIRES AND TRACTION DEVICES
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, using snow tires or traction
devices may be necessary. Ford offers tire cables as a Ford approved
accessory and recommends use of these or SAE class “S” tire cables. See
your authorized dealer for more information on tire cables for your
vehicle.
Follow these guidelines when using snow tires and traction devices:
•Cables or chains should only be used on the rear wheels.
•Install cables or chains securely, verifying that the cables or chains do
not touch any wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the cables or chains rub or bang against
the vehicle, stop and retighten them. If this does not work, remove the
cables or chains to prevent vehicle damage.
•Avoid overloading your vehicle.
•Remove the cables or chains when they are no longer needed.
•Do not use cables or chains on dry roads.
•Do not exceed 30 mph (48 km/h) with tire cables or chains on your
vehicle.
Consult your authorized dealer for information on other Ford Motor
Company approved methods of traction control.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Tire Label or Safety Compliance Certification Label:
Base Curb Weight– is the weight of the vehicle including a full tank of
fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.

Vehicle Curb Weight– is the weight of your new vehicle when you
picked it up from your authorized dealer plus any aftermarket
equipment.
Payload– is the combined weight of cargo and passengers that the
vehicle is carrying. The maximum payload for your vehicle can be found
on the Tire Label on the B-Pillar or the edge of the driver’s door
(vehicles exported outside the US and Canada may not have a Tire
Label). Look for“THE COMBINED WEIGHT OF OCCUPANTS AND
CARGO SHOULD NEVER EXCEED XXX kg OR XXX lb.”for
maximum payload. The payload listed on the Tire Label is the maximum
payload for the vehicle as built by the assembly plant. If any aftermarket
or authorized-dealer installed equipment has been installed on the
vehicle, the weight of the equipment must be subtracted from the
payload listed on the Tire Label in order to determine the new payload.
The appropriate loading capacity of your vehicle can be limited
either by volume capacity (how much space is available) or by
payload capacity (how much weight the vehicle should carry). Once
you have reached the maximum payload of your vehicle, do not add
more cargo, even if there is space available. Overloading or improperly
loading your vehicle can contribute to loss of vehicle control and
vehicle rollover.
