flat tire Mercury Mountaineer 2005 s User Guide

•All-Wheel driving capability (if applicable)
•Load leveling adjustment (if applicable)
When driving with the dissimilar spare tire/wheel additional caution
should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a 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.

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.
•Never use the front or rear
differential as a jacking point.
5. Remove the lug nuts with the lug wrench.
6. Replace the flat tire with the spare tire, making sure the valve stem is
facing outward. Reinstall the lug nuts, cone side in, until the wheel is
snug against the hub. Do not fully tighten the lug nuts until the wheel
has been lowered.
7. Lower the wheel by turning the jack handle counterclockwise.
8. Remove the jack and fully tighten
the lug nuts in the order shown.
Refer toWheel lug nut torque
specificationslater in this chapter
for the proper lug nut torque
specification.
Stowing the flat/spare tire
Note:Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
1. Lay the tire on the ground with the valve stem facing up, toward the
vehicle.
2. Slide the wheel partially under the vehicle and install the retainer
through the wheel center. Pull on the cable to align the components at
the end of the cable.

3. Turn the lug wrench clockwise until the tire is raised to its stowed
position underneath the vehicle. The effort to turn the jack handle
increases significantly and the spare tire carrier ratchets or slips when
the tire is raised to the maximum tightness. Tighten to the best of your
ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
ratchets or slips with little effort, take the vehicle to your dealer for
assistance at your earliest convenience.
4. Check that the tire lies flat against the frame and is properly
tightened. Try to push or pull, then turn the tire to be sure it will not
move. Loosen and retighten, if necessary. Failure to properly stow the
spare tire may result in failure of the winch cable and loss of the tire.
5. If your vehicle is equipped with a spare tire lock and key, be sure to
install the spare tire lock into the bumper drive tube with the spare tire
lock key and jack handle.
6. Repeat this tightness check procedure when servicing the spare tire
pressure (every six months, perscheduled maintenance information),
or at any time that the spare tire is disturbed through service of other
components.
Re-stowing the jack and tools
1. Unblock the wheels.
2. Stow the wheel ornament (if removed) in a safe location in the vehicle
(such as the glove box or jack stowage compartment) so it will not
become damaged. Re-install the wheel ornament onto the wheel once the
tire is repaired or replaced.
3. Stow the jack and tools in their respective locations, making sure they
are fully secured so they do not rattle when you drive.
WHEEL LUG NUT TORQUE SPECIFICATIONS
Retighten the lug nuts to the specified torque at 50–100 miles (80–160
km) after any wheel disturbance (rotation, flat tire, wheel removal, etc.).

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
If your vehicle is stuck in snow, mud, sand, etc.,do notrapidly
spin the tires; spinning the tires can tear the tire and cause an
explosion. A tire can explode in as little as three to five seconds.
Never spin the tires in excess of the 35 mph (55 km/h) point
indicated on the speedometer.
Highway hazards
No matter how carefully you drive there’s always the possibility that you
may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove wheel and replace it with your spare tire and wheel. If
you cannot detect a cause, have the vehicle towed to the nearest repair
facility or tire dealer to have the vehicle inspected.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you’re driving, the wheels may be
out of alignment. Have a qualified technician at a Ford or Lincoln
Mercury dealer check the wheel alignment periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by a qualified technician
at a Ford or Lincoln Mercury dealer. Front wheel drive (FWD) vehicles
and those with an independent rear suspension (if equipped) may
require alignment of all four wheels.

Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear ask a qualified technician at a
Ford or Lincoln Mercury dealership to check for and correct any wheel
misalignment, tire imbalance or mechanical problem involved before tire
rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire/wheel. 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. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note:After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.

TIRE PRESSURE MONITORING SYSTEM (TPMS)(IF EQUIPPED)
When the Tire Pressure Monitoring
System warning light is lit, one or
more of your tires is significantly
under-inflated. You should stop and
check your tires as soon as possible,
and inflate them to the proper pressure as indicated on the vehicle’s tire
information placard (label). Driving on a significantly under-inflated tire
causes the tire to overheat and can eventually lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability. Even if your vehicle is
equipped with a Tire Pressure Monitoring System, it is still important
that you manually check the inflation pressure of your tires regularly.
Each tire, including the spare, should be checked monthly when cold and
set to the recommended inflation pressure which can be found on either
the Safety Compliance Certification Label which is located on the B-Pillar
or the edge of the driver’s door.
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
Inspecting 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.
Changing tires with TPMS
It is recommended that you always
have your tires serviced by a dealer
or qualified technician.Each road
tire is equipped with a tire
pressure sensor mounted on the
wheel inside the tire connected
to 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
whenever the sensor is removed to minimize air leaks.

The tire pressure should be checked periodically (at least monthly) using
an accurate tire gauge, refer toInspecting and 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 every
minute while you are driving and once an hour 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 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.
In short, once the light has turned ON, at least one tire may be under
inflated.
When your temporary spare tire is installed
When one of your road tires needs to be replaced with the temporary
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 the message center messages (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.
