2010 FORD EXPEDITION check engine

WARNING:If a failure has been detected within the
AdvanceTrac
with RSC
system, thesliding caricon
will
illuminate steadily. Verify that the AdvanceTrac
with RSC
system is
not manually disabled (push the AdvanceTrac
with RSC
“Off “
button located on the center of the instrument panel). If thesliding
caricon
still illuminates steadily, have the system serviced by an
authorized dealer immediately. Operating your vehicle with
AdvanceTrac
with RSC
disabled could lead to an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
The AdvanceTrac
with RSC
system provides the following stability
enhancement features for certain driving situations:
•Traction Control (TCS), which functions to help avoid drive-wheel
spin and loss of traction.
•Electronic Stability Control (ESC), which functions to help avoid skids
or lateral slides
•Roll Stability Control™ (RSC
), which functions to help avoid a
vehicle roll-over.
The AdvanceTrac
with RSC
system automatically enables each time
the engine is started. All features of the AdvanceTrac
with RSC
system
(TCS, ESC, and RSC
are active and monitor the vehicle from start-up).
However, the system will only intervene if the driving situation requires
it.
The AdvanceTrac
with RSC

system includes an AdvanceTrac

with RSC
“Off” button on the
center of the instrument panel, and
a “sliding car” icon
in the
instrument cluster. The “sliding car”
icon
in the instrument cluster will illuminate temporarily during
start-up as part of a normal system self-check, or during driving if a
driving situation causes the AdvanceTrac
with RSC
system to operate.
If the “sliding car” icon
illuminates steadily, verify that the
AdvanceTrac
with RSC
system is not manually disabled by pressing
the AdvanceTrac
with RSC
“Off” button located on the center of the
instrument panel. If the “sliding car” icon
remains steadily
illuminated, have the system servicedd by an authorized dealer
immediately. The message center will also indicate a failure with the
AdvanceTrac
with RSC
system.

Note:If the system cannot be turned off, refer toMyKey™in theLocks
and Securitychapter for more information.
When AdvanceTrac
with RSC
performs a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTrac
with RSC
you may
experience the following:
•A slight deceleration of the vehicle
•The “sliding car”
indicator light will flash.
•A vibration in the pedal when your foot is on the brake pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
Traction Control (TCS)
Traction Control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem: Engine Traction Control and Brake Traction
Control. Engine Traction Control works to limit drive-wheel spin by
momentarily reducing engine power. Brake Traction Control works to
limit wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction Control is most active at low speeds.
During Traction Control events the “sliding car” icon
in the
instrument cluster will flash.
If the Traction Control system is activated excessively in a short period
of time, the braking portion of the system may become temporarily
disabled to allow the brakes to cool down. In this situation, Traction
Control will use only engine power reduction or transfer to help control
the wheels from over-spinning. When the brakes have cooled down, the
system will regain all features. Anti-lock braking, RSC
, and ESC are not
affected by this condition and will continue to function during the
cool-down period.
The Engine Traction Control and Brake Traction Control system may be
deactivated in certain situations. See theSwitching Off Traction
Controlsection following.

Switching Off Traction Control
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off the Traction Control features of the AdvanceTrac

with RSC
system may be beneficial because the wheels are allowed to
spin. This will restore full engine power and will enhance momentum
through the obstacle. To switch off the Traction Control press the
AdvanceTrac
with RSC
“Off” button. Full features of the AdvanceTrac

with RSC
system can be restored by pressing the AdvanceTrac
with
RSC
Offbutton again or by turning off and restarting the engine.
If you switch off the Traction Control, the sliding caricon
will
illuminate steadily. Pressing the AdvanceTrac
with RSC
“Off” button
again will turn off “sliding car” icon
.
In R (Reverse), ABS and the Engine and Brake Traction Control features
will continue to function; however, ESC and RSC
are disabled.

Trailer Sway Control
Your vehicle may be equipped with trailer sway control. When properly
equipped, trailer sway control will use the vehicle’s AdvanceTrac
with
RSC
system to detect and help reduce trailer sway by applying brake
force at individual wheels and, if necessary, by reducing engine power.
WARNING:Trailer sway control does not prevent a trailer from
swaying, it mitigates the sway from increasing once it has
occurred. If you are experiencing trailer sway it is likely that the trailer
is improperly loaded for the correct tongue weight or the speed of the
vehicle and trailer is too high. Pull the vehicle-trailer over to a safe
location to check the trailer weight distribution and tongue load and
reduce speed to a safe level while towing. If trailer sway is
experienced, SLOW DOWN.
Driving

During trailer sway control events the “sliding car”icon in the
instrument cluster will flash momentarily. The cluster message center
will also displayTRAILER SWAY REDUCE SPEED. In some cases
when trailer sway is detected, the vehicle speed is too high and may be
above a speed at which trailer sway will not grow continuously. This may
cause the system to activate multiple times, causing a gradual reduction
in speed.
Note:The trailer sway control will only activate at speeds greater than
40 mph (64 km/h).
Disabling Trailer Sway Control
Trailer sway control can be disabled during any key cycle. SeeMessage
centerin theInstrument Clusterchapter. Note that regardless of
chosen enable state, trailer sway control will be re-enabled at each new
key cycle.
WARNING:Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury, or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (e.g., hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
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 help 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.
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
Driving

2010 Expedition(exd)
Owners Guide(own2002), 1st Printing
USA(fus)

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
Variable assist steering
Your vehicle is equipped with variable assist power steering. At low
engine RPM, steering assist will adjust to reduce efforts and improve low
speed maneuverability. At high engine RPM, the assist will adjust to
improve steering feel at high speeds.
If the amount of effort required to steer your vehicle changes while
driving at a constant engine RPM, have the power steering system
checked by your authorized dealer.
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride, handling and
general vehicle performance during:
•Certain road conditions
•Steering maneuvers
•Braking
•Acceleration
This system keeps the rear of your vehicle at a constant level by
automatically adding air or releasing air from the springs. If you exceed
the load limit, the rear air suspension may not operate. The air
suspension system will stay active for 40 minutes after the ignition is
turned off to accommodate any load changes. (The air compressor may
run when the vehicle is off; this is normal.)
The air suspension system can be enabled or disabled through the
message center. Refer toMessage centerin theInstrument cluster
chapter.

Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
If your vehicle is equipped with AdvanceTrac
with RSC, press the
AdvanceTrac
with RSC button (refer toAdvanceTrac
with Roll
Stability Control (RSC) Stability Enhancement Systemin this
chapter) while driving in deep sand if you experience excessive engine
power reduction.
Mud and water
If you must drive through high
water, drive slowly. Traction or
brake capability may be limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If the ignition system gets wet, the
vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even four–wheel drive vehicles can lose traction in
slick mud. As when you are driving over sand, apply the accelerator
slowly and avoid spinning your wheels. If the vehicle does slide, steer in
the direction of the slide until you regain control of the vehicle.
If the transmission, transfer case, front axle or rear axle are submerged
in water, their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
