2005 FORD EXPEDITION brake

The ABS operates by detecting the onset of wheel lockup during brake
applications and compensates for this tendency. The wheels are
prevented from locking even when the brakes are firmly applied.
Using ABS
•In an emergency or when maximum efficiency from the four-wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain steering
control of your vehicle and, providing there is sufficient space, will
enable you to avoid obstacles and bring the vehicle to a controlled
stop.
•The anti-lock system does not always reduce stopping distance.
Always leave enough room between your vehicle and the vehicle in
front of you to stop.
•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
ABS warning lamp
The ABS warning lamp in the
instrument cluster momentarily
illuminates when the ignition is
turned on. If the light does not
illuminate momentarily at start up,
remains on or continues to flash, the ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately.)
Brake Assist (if equipped)
The Brake Assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and
maximizes the amount of brake booster assist, helping the driver to
achieve maximum braking pressure. Once a panic brake application is
detected, the system will remain activated as long as the brake pedal is
depressed. The system is deactivated by releasing the brake pedal.
When the system activates, the brake pedal will travel with very little
effort; this is normal.

Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is released.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.
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.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
•Do not operate the vehicle with the 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:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride comfort, vehicle
handling and general vehicle performance by adjusting the vehicle’s ride
height according to vehicle speed, weight added to or removed from the
vehicle and four-wheel drive (if equipped) operation. Normal vehicle
operation does not require any action by the driver.
When you enter the vehicle and the ignition is off, the air suspension will
have automatically lowered the vehicle to its lowest height to provide

Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions, such as
slower speeds and increased stopping distance, should be taken when
driving a heavily loaded vehicle.
Your vehicle has the capability to haul more cargo and people than most
passenger cars. Depending upon the type and placement of the load,
hauling people and cargo may raise the center of gravity of the vehicle.
Use extra caution while becoming familiar with your vehicle. Know the
capabilities and limitations of both you as a driver and your vehicle.
ADVANCETRACWITH ROLL STABILITY CONTROL (RSC)
STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED)
The AdvanceTrac
with RSC system provides stability enhancement
features such as Roll Stability Control, AdvanceTrac
with RSC and
traction enhancement for certain driving situations when driver
assistance is needed. 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
with RSC system off by pressing the AdvanceTrac

with RSC button. This will allow your tires to “dig” for traction.
If the AdvanceTrac
with RSC system is activated and deactivated
excessively in a short period of time, the brake portion of the system will
shut down to allow the brakes to cool down. A limited AdvanceTrac

with RSC 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.
The AdvanceTrac
with RSC system 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
with RSC system helps the driver maintain steering
control if the vehicle begins to slide excessively left or right or spin out.
AdvanceTrac
with RSC 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 the AdvanceTrac
with RSC
system, 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 toTrailer
Towingin this chapter)
The RSC feature works to further enhance the vehicle’s overall stability
during aggressive maneuvers. The RSC feature helps maintain roll
stability of the vehicle during aggressive maneuvers by applying brake
force to one or more wheels.
The AdvanceTrac
with RSC 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
with RSC button
allows the driver to control the
availability of the AdvanceTrac

with RSC system. The RSC system
status is indicated by a warning
indicator light with a “sliding car” icon in the instrument cluster that will
flash when the system is activated 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
with RSC 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 button once will disable the AdvanceTrac
with RSC
stability enhancement system 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 button for more than five seconds will disable the AdvanceTrac

with RSC stability enhancementandtraction enhancement feature. If the
vehicle is stuck in snow or mud or when driving in deep sand, switching
off the AdvanceTrac
with RSC 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

with RSC stability enhancement system 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
with RSC performs a system self-check. During
AdvanceTrac
with RSC system operation you may experience the
following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•The AdvanceTrac
with RSC 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
with RSC
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
with Roll Stability Control 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
with Roll Stability Control sensors
located in this area.
Note:Pressing the AdvanceTrac
with RSC button will disable the
AdvanceTrac
with RSC system.
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
with
Roll Stability Control 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.
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock
This vehicle is equipped with a park/brake-shift interlock feature that
prevents the gearshift lever from being moved from P (Park) when the
ignition is in the ON position unless 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, or when the ignition is
in the OFF position, it is possible that a fuse has blown or the vehicle’s
brakelamps are not operating properly. Refer toFuses and relaysin the
Roadside Emergencieschapter.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to OFF, then remove the
key.
2. Push the tilt steering lever down and tilt the steering column all the
way up.
