system is off, the indicator will be illuminated. If a
system fault is detected while the traction control
system in on, the indicator lamp on the traction
control switch will be illuminated and your vehicle
should be serviced.
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 a Traction
Controlevent is an indication that at least some
of the tires have exceeded their ability to grip the
road; this may lead to an increased risk of loss of
vehicle control, vehicle rollover, personal injury
and death. If you experience a severe road event,
SLOW DOWN.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery
surfaces, particularly when one wheel is on a poor
traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle.
Extended use of other than the manufacturer’s
specified size tires on a Traction-Lok rear axle could
result in a permanent reduction in effectiveness.
This loss of effectiveness does not affect normal
driving and should not be noticeable to the driver.
AUTOMATIC TRANSMISSION OPERATION
(IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock
feature that prevents the gearshift lever from being
moved from P (Park) when the ignition is in the ON
position unless the brake pedal is depressed.
If you cannot move the gearshift lever out of P
(Park) with ignition in the ON position and the
brake pedal depressed:
1. Apply the parking brake, turn ignition key to
LOCK, then remove the key.

and is designed for emergency use only. Replace this
tire with a full-size tire as soon as possible.
Installing a tire on either or both sides of the driven
axle that is of a different size than the original road
tire is not recommended since this will affect the
accuracy of the speedometer and odometer. If
different size tires must be installed, it is important
that all four be the same size.
If one or more tires of the four are of a
different size, the ABS and traction control
system (if equipped) may not function correctly or
may not function at all. The temporary spare
supplied with the vehicle is the only different size
tire that should ever be installed.
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.
When driving with the temporary spare tire do not:
• use more than one temporary spare tire at a time
• exceed 80 km/h (50 mph) or drive further than
3,200 km (2,000 miles) total under any
circumstances
• load the vehicle beyond maximum vehicle load
rating listed on the tire pressure label on the
driver’s side b-pillar
• tow a trailer
• use tire chains
• drive through an automatic car wash, because of
the vehicle’s reduced ground clearance
• try to repair the temporary spare tire or remove it
from its wheel
• use the wheel for any other type of vehicle
Use of a temporary spare tire at any one wheel
location can lead to impairment of the following:

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.
To remove the
anti-theft lug nut:
1. Insert the key over
the locking lug nut.
Make sure you hold the key square to the lug nut. If
you hold the key at an angle, you could damage the
key and the lug nut.
2. Place the lug nut wrench over the lug nut key and
apply pressure on the key with the wrench.
3. Turn the wrench in a counterclockwise direction
to remove the lug nut.
To install the anti-theft lug nut:

•Sudden or hard accelerations may reduce fuel
economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 88 km/h
[55 mph] uses 15% less fuel than traveling at
105 km/h [65 mph]).
•Revving the engine before turning it off may
reduce fuel economy.
•Using the air conditioner or defroster may reduce
fuel economy.
•You may want to turn off the speed control in
hilly terrain if unnecessary shifting between third
and fourth gear occurs. Unnecessary shifting of
this type could result in reduced fuel economy.
•Warming up a vehicle on cold mornings is not
required and may reduce fuel economy.
•Resting your foot on the brake pedal while driving
may reduce fuel economy.
•Combine errands and minimize stop-and-go
driving.
Maintenance
•Keep tires properly inflated and use only
recommended size.
•Operating a vehicle with the wheels out of

SNOW TIRES AND CHAINS
Driving too fast for conditions creates the
possibility of loss of vehicle control. Driving
at very high speeds for extended periods of time
may result in damage to vehicle components.
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. Use chains on the tires only in an emergency
or if the law requires them.
Follow these guidelines when using snow tires and
chains:
•Chains may damage aluminum wheels.
•Use only Cable Type chains with size P225/55R16
or 245/45ZR17 tires. Use of SAE Class S chains
may damage your vehicle.
•Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.
•Drive 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.
•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
•The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.
