Driving -> ADVANCETRAC? STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED) for Your Ford Explorer SUV Third Generation (2002-2005)

Driving  
The BRAKE warning lamp in the  
instrument cluster illuminates and  
remains illuminated (when the  
ignition is turned ON) until the  
parking brake is released.  
Always set the parking brake fully and make sure that the  
gearshift is securely latched in P (Park).  
The parking brake is not recommended to stop a moving vehicle.  
However, if the normal brakes fail, the parking brake can be used to stop  
your vehicle in an emergency. Since the parking brake applies only the  
rear brakes, the vehicle’s stopping distance will increase greatly and the  
handling of your vehicle will be adversely affected.  
Pull the release lever to release the  
brake. Driving with the parking  
brake on will cause the brakes to  
wear out quickly and reduce fuel  
economy.  
ADVANCETRACி STABILITY ENHANCEMENT SYSTEM  
(IF EQUIPPED)  
The AdvanceTrac௢ system provides a stability enhancement feature as  
well as a traction enhancement feature. It helps your vehicle maintain  
traction, when driving on slippery and/or hilly road surfaces, by detecting  
and controlling wheel spin. Excessive wheel spin is controlled by  
momentarily reducing engine power and rapidly applying the anti-lock  
brakes. The system is a driver aid which makes your vehicle easier to  
handle primarily on snow and ice-covered roads.  
If your vehicle should become stuck in deep snow or mud, try switching  
the AdvanceTrac௢ system off by pressing the AdvanceTrac௢ button.  
This will allow your tires to “dig” for traction.  
If the AdvanceTrac௢ system is activated excessively in a short period of  
time, the brake portion of the system will shut down to allow the brakes

Driving  
to cool down. A limited AdvanceTrac௢ function using only engine power  
reduction will still help control the wheels from over-spinning. When the  
brakes have cooled down, the system will again function normally.  
Anti-lock braking is not affected by this condition and will function  
normally during the cool-down period.  
AdvanceTrac௢ enhances your vehicle’s stability during maneuvers that  
require all available tire traction, like in wet/snowy/icy road conditions  
and/or when performing emergency maneuvers. In an emergency  
lane-change, the driver will experience better overall vehicle traction,  
and have better control of the vehicle.  
The AdvanceTrac௢ system helps the driver maintain steering control if  
the vehicle begins to slide excessively left or right or spin out.  
AdvanceTrac௢ will attempt to correct the sliding motion by applying  
brake force at individual tires and, if necessary, by reducing engine  
power.  
Driving conditions which may activate AdvanceTrac௢ include:  
• Taking a turn too fast  
• Maneuvering quickly to avoid an accident, pedestrian or obstacle  
• Hitting a patch of ice  
• Changing lanes on a snow-rutted road  
• Entering a snow-free road from a snow-covered side street, or vice  
versa  
• Entering a paved road from a gravel road, or vice versa  
• Hitting a curb while turning  
• Driving on slick surfaces  
• Cornering while towing a heavily loaded trailer (refer to Trailer  
Towing in this chapter)  
The AdvanceTrac௢ system automatically turns on when the engine is  
started. However, the system does not function when the vehicle is  
traveling in R (Reverse) or, if equipped with four-wheel drive, in 4L (4X4  
LOW). In R (Reverse) or in 4L (4X4 LOW), ABS and the traction  
enhancement feature will continue to function.  
The AdvanceTrac௢ button allows  
the driver to control the availability  
of the AdvanceTrac௢ system.  
AdvanceTrac௢ system status is  
indicated by a warning indicator  
143

light with a “sliding car” icon in the instrument cluster that will flash  
when the system is active and an indicator light in the control button  
that will illuminate when the system is turned off. In vehicles with a  
message center, the message “ADVANCETRAC OFF” will be displayed.  
If a failure is detected in the AdvanceTrac௢ system, the warning  
indicator light in the instrument cluster will stay on. If the warning  
indicator light in the instrument cluster remains on while the engine is  
running, have the system serviced immediately.  
Pressing the control once will disable the AdvanceTrac௢ stability  
enhancement and the engine power reduction portion of the traction  
enhancement feature; the brake portion of the traction enhancement  
feature will still function normally. Pressing and holding the control for  
more than five seconds will disable the AdvanceTrac௢ stability  
enhancement and traction enhancement feature. If the vehicle is stuck  
in snow or mud or when driving in deep sand, switching off the  
AdvanceTrac௢ system may be beneficial so the wheels are allowed to  
spin. If your vehicle seems to lose engine power while driving in deep  
sand or very deep snow, switching off the AdvanceTrac௢ stability  
enhancement feature will restore full engine power and will enhance  
momentum through the obstacle.  
Some drivers may notice a slight movement of the brake pedal when the  
AdvanceTrac௢ performs a system self-check. During AdvanceTrac௢  
operation you may experience the following:  
• A rumble or grinding noise  
• A slight deceleration of the vehicle  
• The AdvanceTrac௢ indicator light will flash  
• 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 rear console or either rear seat. The  
speaker vibrations can adversely affect the AdvanceTrac௢  
sensors located in this area.

Driving  
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 improperly inflated tire  
• uneven tire wear  
• loose or worn suspension components  
• loose or worn steering components  
• improper steering alignment  
A high crown in the road or high crosswinds may also make the steering  
seem to wander/pull.  
PREPARING TO DRIVE YOUR VEHICLE  
Utility vehicles have a significantly higher rollover rate than  
other types of vehicles.  
In a rollover crash, an unbelted person is significantly more likely  
to die than a person wearing a safety belt.  
Your vehicle has larger tires and increased ground clearance, giving the  
vehicle a higher center of gravity than a passenger car.
