ADVANCETRACSTABILITY ENHANCEMENT SYSTEM
(IF EQUIPPED)
The AdvanceTracsystem helps the driver maintain the stability and
steer-ability of the vehicle. The system integrates anti-lock braking
system (ABS) and Traction Control™ and a more advanced function to
further enhance the stability of the vehicle.
AdvanceTracconstantly monitors the vehicle motion relative to the
driver’s intended course. This is done by using added sensors that
compare the steering inputs from the driver with the actual motion of
the vehicle. AdvanceTracdetermines whether an engine torque
reduction or brake application is needed to help control the vehicle. If
the vehicle begins to rotate excessively left or right, spin out, or slide
sideways, the system will attempt to correct the excessive motion. If the
vehicle does not respond to steering inputs, the system will attempt to
increase the turning response of the vehicle.
AdvanceTracenhances 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.
Driving conditions which may activate AdvanceTracinclude:
•Accelerating on a slippery surface
•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
•Cornering at excessive speeds while towing a heavily loaded trailer
(refer toTrailer towingin theTires, Wheels and Loadingchapter)
The AdvanceTracsystem automatically turns on when the engine is
started. However, the system does not function when the vehicle is
traveling in R (Reverse).

If you are operating the speed control system and road conditions
change causing the AdvanceTracto activate, the AdvanceTracwill
disengage the speed control. When driving conditions permit, you can
return to speed control by pressing the RES control. Refer toSpeed
controlin theDriver controlschapter.
The AdvanceTracbutton allows the
driver to control the availability of
the AdvanceTracsystem.
AdvanceTracsystem status is
indicated by the AdvanceTrac
indicator light in the instrument
cluster when the system is deactivated.
The AdvanceTracsystem cannot be deactivated when the vehicle speed
is above 45 mph (70 km/h) even though the AdvanceTracindicator light
may be illuminated in the instrument cluster.
If a failure is detected in the AdvanceTracsystem, the AdvanceTrac
indicator light in the instrument cluster will stay on. Have the vehicle
system serviced by an authorized dealer immediately.
If the vehicle is stuck in snow or mud or when driving in deep sand,
switching off the AdvanceTracsystem 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
AdvanceTracperforms a system self-check. During AdvanceTrac
operation you may experience the following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•The AdvanceTracindicator light will illuminate
•
If your foot is on the brake pedal, you will feel a vibration in the pedal.
All these conditions are normal during AdvanceTracoperation.
If the AdvaceTrac system is activated for an extended period of time, the
brake portion of the system will shut down to allow the brakes to cool
down. A limited AdvanceTracfunction 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.

Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTracsystem. Also, do not install a stereo
loudspeaker near the front center console or under either front
seat. The speaker vibrations can adversely affect the
AdvanceTracsensors 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 AdvanceTracevent
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 CONTROL™ (IF EQUIPPED)
Your vehicle may be equipped with a Traction Control™ system. This
system helps you maintain the stability and steerability of your vehicle. It
is especially useful on slippery road surfaces. The system operates by
detecting and controlling wheel spin. The system borrows many of the
electronic elements already present in the anti-lock braking system
(ABS).
Wheel-speed sensors allow excess wheel spin to be detected by the
Traction Control™ portion of the ABS computer. Excess wheel spin is
controlled through either engine or brake torque reduction. This is
realized via the fully electronic engine control system. This process is
very sensitive to driving conditions and very fast acting. The wheels
“search” for optimum traction several times a second and adjustments
are made accordingly.
The Traction Control™ system will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads.
During Traction Control™ operation the engine will not “rev-up” when
you push further on the accelerator. This is normal system behavior.

If you should become stuck in deep
snow or on a very slippery road
surface, try switching the Traction
Control™ system off. This may
allow excess wheel spin to “dig” the
vehicle out or enable a successful
“rocking” maneuver.
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 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.
STEERING
To help 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.
It is also important to maintain a proper power steering fluid level in the
power steering fluid reservoir:
•Do not operate the vehicle with a low power steering pump fluid level.
SeeChecking and adding power steering fluidin theMaintenance
and Specificationschapter.
•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 maximum
level, as this may result in leaks from the reservoir. SeeChecking and
adding power steering fluidin theMaintenance and Specifications
chapter.
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

D (Drive) with Grade Assist
Overdrive can be deactivated by
pressing the transmission control
switch on the side of the gearshift
lever. This will also activate Grade
Assist.
•Transaxle operates in gears one
through five.
•Provides engine braking.
Depending on conditions the
transaxle will automatically
downshift to increase the level of
engine braking while descending
grades.
•Use when driving conditions
cause excessive shifting from O/D to other gears. Examples: hilly
terrain, mountainous areas and when engine braking is required.
•O/D OFF lamp in the instrument
cluster is illuminated.
•To return to O/D (overdrive mode), press the transmission control
switch. The O/D OFF lamp in the instrument cluster will not be
illuminated.
•
O/D (overdrive) is automatically returned each time the key is turned off.
L (Low)
•Provides maximum engine braking.
•Will downshift to the lowest available gear for the current vehicle
speed; allows for first gear when vehicle reaches slower speeds.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.

ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with a full-time All Wheel Drive (AWD)
system. With the AWD option, power will be delivered to the front
wheels and distributed to the rear wheels as needed. The AWD system is
active all the time and requires no input from the operator.
All components of the AWD system are sealed for life and require no
maintenance.
If your vehicle is equipped with AWD, a spare tire of a different size
other than the tire provided should never be used. A dissimilar spare tire
size (other than the spare tire provided) or major dissimilar tire sizes
between the front and rear axles could cause the AWD system to stop
functioning and default to front wheel drive.
Note:Your AWD vehicle is not intended for off-road use. The AWD
feature gives your vehicle some limited off-road capabilities in which
driving surfaces are relatively level, obstruction-free and otherwise
similar to normal on-road driving conditions. Operating your vehicle
under other than those conditions could subject the vehicle to excessive
stress which might result in damage which is not covered under your
warranty.
Driving off-highway with AWD vehicles
AWD vehicles are specially equipped for driving on sand, snow, mud and
rough roads and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the highway.
When driving at slow speeds off-highway under high outside
temperatures, use L (Low) gear when possible. L (Low) gear operation
will maximize the engine and transmission cooling capability.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.
Basic operating principles
•Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
•Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
If your vehicle goes off the edge of the pavement
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.

•It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or rollover. Remember, your safety and the
safety of others should be your primary concern.
If your vehicle gets stuck
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
If your vehicle is equipped with Traction Control™, it may be beneficial
to disengage the Traction Control™ system while attempting to rock the
vehicle.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
Do not spin the wheels at over 35 mph (56 km/h). The tires may
fail and injure a passenger or bystander.
Emergency maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle (i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency). Excessive steering will result in less vehicle control,
2008 Taurus(tau)

232

not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
AWD Systems (if equipped)
AWD uses all four wheels to power the vehicle. This increases traction,
enabling you to drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
If your vehicle is equipped with a 6–speed transmission:When
driving at slow speeds in deep sand under high outside temperatures,
use L (Low) gear when possible. L (Low) gear operation will maximize
the engine and transmission cooling capability.Do not perform this
operation if your vehicle is equipped with an
electronically-controlled CVT.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.
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.
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.
