wheel size Mercury Sable 1999 Owner's Manuals

When one of the front wheels is off the
ground, the transaxle alone will not prevent
the vehicle from moving or slipping off the jack,
even if the vehicle is in P (Park).
To prevent the vehicle from moving when
you change a tire, be sure the parking brake
is set, then block (in both directions) the wheel
that is diagonally opposite (other side and end of
the vehicle) to the tire being changed.
If the vehicle slips off the jack, you or
someone else could be seriously injured.
2. Place gearshift lever
in P (Park), turn
engine OFF, block the
diagonally opposite
wheel, then remove the
spare tire, jack and lug wrench.
²In the sedan, these
are located in the
trunk cargo area
storage
compartment.
²In the wagon, they
are stored in the left
side rear trim panel
for the temporary
spare and in the
floor cargo area
storage compartment
for the full size
spare.

SNOW TIRES AND CHAINS
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, you may need to use snow tires and
chains. If you need to use chains, it is recommended
that steel wheels (of the same size and
specifications) be used as chains may chip aluminum
wheels.
Follow these guidelines when using snow tires and
chains:
²Use only SAE Class S chains.
²Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or
bang against your vehicle, stop and re-tighten the
chains. If this does not work, remove the chains
to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
²The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.

an overfilled tank may cause leakage and
lead to fuel spray and fire.
Maintenance and care

²Drive at reasonable speeds (traveling at 105 km/h
[65 mph] uses 15% more fuel than traveling at
88 km/h [55 mph]).
²Revving the engine before turning it off may
reduce fuel economy.
²Use of the air conditioner or defroster may reduce
fuel economy.
²Use of speed control (if equipped) may improve
fuel economy. Speed control can help maintain a
constant speed and reduce speed changes. You
may want to turn off the speed control in hilly
terrain as unnecessary shifting between third and
fourth gears may occur and could result in
reduced fuel economy.
²Warming up a vehicle on cold mornings is not
required and may reduce fuel economy.
²Resting your foot on the brake pedal while driving
may reduce fuel economy.
²Combine errands and minimize stop-and-go
driving.
Maintenance
²Keep tires properly inflated and use only
recommended size.
²Operating a vehicle with the wheels out of
alignment will reduce fuel economy.
²Use recommended engine oil. Refer toLubricant
Specifications.
²Perform all regularly scheduled maintenance
items. Follow the recommended maintenance
schedule and owner maintenance checks found in
your vehicle Scheduled Maintenance Guide.
Conditions
²Heavily loading a vehicle or towing a trailer may
reduce fuel economy at any speed.
