1999 Mercury Grand Marquis spare wheel

The traction control indicator
flashes during a Traction Controly
system event.
If the traction control indicator
comes on and stays lit, either:
²the Traction Controlysystem
requires service, or
²the customer has disabled the
system using the traction control switch located on the left side of the
glove compartment.
The Traction Controlysystem will be on every time you turn the ignition
key from OFF to ON until you deactivate the system using the traction
control switch in the glove compartment.
The traction control must be turned off if you are using a mini-spare tire
in a rear tire position.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to help steer the vehicle.
To prevent damage to the power steering pump:
²Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
²Do not operate the vehicle with a low power steering pump fluid level.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, the condition could be caused by any of
the following:
²underinflated tire(s) on any wheel(s)
²high crown in center of road
²high crosswinds
²wheels out of alignment
²loose or worn components in steering linkage

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.
Temporary spare tire information
Your vehicle may have a temporary or full-size spare tire. The temporary
spare tire for your vehicle is labeled as such. It is smaller than a regular
tire and is designed for emergency use only. Replace this tire with a
full-size tire as soon as possible.
If you use the temporary spare tire continuously or do not follow
these precautions, the tire could fail, causing you to lose control
of the vehicle, possibly injuring yourself or others.
Roadside emergencies

When driving with the temporary spare tiredo not:
²exceed 80 km/h (50 mph) under any circumstances
²load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
²tow a trailer
²use tire chains
²drive through an automatic car wash, because of the vehicle's reduced
ground clearance
²try to repair the temporary spare tire or remove it from its wheel
²use the wheel for any other type of vehicle
If the mini-spare tire is used as a replacement for a rear wheel:
²Turn off the traction control switch (if equipped).
Tire change procedure
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.
1. Park on a level surface, activate hazard flashers and set parking brake.
2. Place gearshift lever in P (Park) and turn engine OFF.
3. Remove the spare tire, jack and
lug wrench.
4. Locate pry off notch (if
equipped) and remove the center
ornament from the aluminum wheel
with the tapered end of the wheel
nut wrench that came with your
vehicle. Insert and twist the handle,
then pry against the wheel.
Roadside emergencies
127

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.
²Never use the rear differential
as a jacking point.
7. Remove the lug nuts with the lug wrench.
8. Replace the flat tire with the spare tire, making sure the valve stem is
facing outward. Reinstall lug nuts until the wheel is snug against the hub.
Do not fully tighten the lug nuts until the wheel has been lowered.
9. Lower the wheel by turning the jack handle counterclockwise.
10. Remove the jack and fully
tighten the lug nuts in the order
shown.
11. Put flat tire, jack and lug wrench
away.
12. If using a mini-spare tire, turn
off the traction control switch (if
equipped).
13. Turn on the air suspension
switch (if equipped).
Anti-theft lug nuts (if equipped)
If your vehicle is equipped with this
feature, one of the lug nuts on each
wheel must be removed and
replaced with a special key. The key
and registration card are attached to
the lug wrench and stored with the spare tire. If you lose the key, send
the registration card to the manufacturer (not the dealer) to get a
replacement key. If the lug wrench/lug nut key assembly is lost, see your
nearest Ford or Lincoln/Mercury dealer who has access to the master set
of keys.Do not use an impact wrench with the anti-theft key.
