2003 FORD WINDSTAR wheel alignment

•A slight deceleration of the vehicle
•The TRAC ACTIVE indicator light will illuminate
•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 AdvanceTrac
operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac
system. Also, do not install a stereo
loudspeaker near the front center console or under either front
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 AdvanceTrac
event
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.
STEERING
To prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
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, check for:
•an underinflated tire
•uneven tire wear
•loose or worn suspension
components•loose or worn steering
components
•improper steering alignment

•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 alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.

which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
SERVICING YOUR TIRES
Low tire warning
The low tire warning system is designed to detect a significant loss of
inflation inany one of your tireson your vehicle. The system uses the
Anti-lock brake wheel speed sensors to detect a change in wheel speed
due to tire deflation.
When a tire loses inflation, the low
tire warning system detects the
change and illuminates the low tire
warning indicator light as shown.
If the light remains on while driving,
check the tire pressure refer to“Checking the tire pressure”in this
chapter. The low tire warning indicator light will also illuminate when
using a temporary spare, refer to“Changing the tires”in theRoadside
emergencieschapter.
The low tire warning system may not detect an under-inflated
tire under all conditions and is not a substitute for manually
checking tires regularly for proper inflation.
When to RESET the Low Tire Warning System:
after any of the following
•Tire rotation
•One or more tires have been replaced
•Tire balancing
•Wheel alignment
•Adjusting the pressure on one or more tires (note: tire pressures are
often adjusted during oil change service)
Maintenance and Specifications
215

•Two or more under inflated tires.
•Sudden loss of tire pressure.
•Vehicle speeds less than 30 km/h (20 mph), greater than 120 km/h
(70 mph) or driving duration less than 10 miles.
•Transporting a heavy load or towing a trailer.
•A different tire was replaced and was not the same brand, type, size,
speed rating, load carrying capacity and DOT code as the other tire on
the same axle.
•System was not reset after tire rotation, air pressure adjustment, a tire
change, wheel alignment or tire balancing.
•System was not reset after the ABS warning lamp illuminates.
The low tire warning feature can be turned off by your dealer.
Checking the tire pressure
•Use an accurate tire pressure gauge.
•Check the tire pressure when tires are cold, after the vehicle has been
parked for at least one hour or has been driven less than 5 km
(3 miles).
•Adjust tire pressure to recommended specifications found on the
Certification Label.
•Reset low tire warning system
Improperly inflated tires can affect vehicle handling and can fail
suddenly, possibly resulting in loss of vehicle control.
Tire rotation
Because your vehicle’s tires perform different jobs, they often wear
differently. To make sure your tires wear evenly and last longer, rotate
them as indicated in the scheduled maintenance guide. If you notice that
the tires wear unevenly, have them checked.
