2002 Mercury Mountaineer brake sensor

Warning messages that have been reset are divided into three categories:
•They will reappear on the display every minute from the reset.
•They will reappear on the display ten minutes from the reset.
•They will not reappear until an ignition OFF-ON cycle has been
completed.
This acts as a reminder that these warning conditions still exist within
the vehicle.

spin. If your vehicle seems to lose engine power while driving in deep
sand or very deep snow, switching off the AdvanceTracstability
enhancement feature will restore full engine power and will enhance
momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTracperforms a system self-check. During AdvanceTrac
operation you may experience the following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•The AdvanceTracindicator light will flash
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTracoperation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTracsystem. Also, do not install a stereo
loudspeaker near the rear console or either rear seat. The
speaker vibrations can adversely affect the AdvanceTrac
sensors located in this area.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an AdvanceTracevent
is an indication that at least some of the tires have exceeded their
ability to grip the road and that you may lose control of the vehicle. If
you experience a severe road event, SLOW DOWN.
If you find yourself regularly experiencing AdvanceTracevents,
you are driving too fast for conditions, you should reduce your
speed, and drive less aggressively. It is always possible to lose control
of a vehicle due to inappropriate driving habits under severe
conditions. The occurrence of an AdvanceTracevent is an indication
that at least some of the tires have exceeded their ability to grip the
road; this may cause you to lose control of the vehicle increasing the
risk of severe personal injury or property damage.

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.
The use of tire sealants is not recommended and may
compromise the integrity of your tires. The use of tire sealants
may also affect your tire pressure monitoring system (if equipped).
If your vehicle is equipped with a tire pressure monitoring
system, refer to Tire Pressure Monitoring System (if equipped)
in theMaintenance and caresection for important information. If the
tire pressure monitor sensor becomes damaged, it will no longer
function.
Spare tire information
The spare tire can be used as a spare or a regular tire. The spare is
identical to the other tires on your vehicle, although the wheel will not
match.
If your vehicle is equipped with AWD, a spare tire of a different
size than the road tires should not be used. Use of such a tire
could result in damage to driveline components and an increased risk
of loss of vehicle control, vehicle rollover, personal injury or death.
Roadside emergencies

ChangingtireswithTPMS
It is recommended that you always
have your tires serviced by a dealer
or qualified technician.Each tire is
equipped with a tire pressure
sensor mounted on the wheel
inside the tire behind the valve
stem. The tire pressure sensor
must be unbolted from the wheel prior to tire removal. The
sensor can be removed by loosening the nut at the valve stem.
Failure to remove the sensor may damage it.The rubber grommet
(washer) between the wheel and the tire pressure sensor needs to be
replaced when any tire is changed to minimize air leaks.
The tire pressure should be checked periodically (at least monthly) using
a tire gauge, refer toChecking the tire pressurein this chapter.
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”. See your
dealer or qualified service technician 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 48 km/h (30 mph) with tire cables or chains on your
vehicle.
