engine FORD TAURUS 2010 6.G Service Manual

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 and ESC 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 AdvanceTrac

section below.
Electronic Stability Control (ESC)
Electronic Stability Control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.
During Electronic Stability Control events the “sliding car” icon
in the
instrument cluster will flash.
Certain adverse driving maneuvers may activate the Electronic Stability
Control system, which include but are not limited to:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Driving over a patch of ice or other slippery surfaces
•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
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter).

Switching Off AdvanceTrac

If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTrac
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 AdvanceTrac
system press the AdvanceTrac
Off
control switch. Full features of the AdvanceTrac
system can be restored
by pressing the AdvanceTrac
Offcontrol switch again or by turning off
and restarting the engine.
When the AdvanceTrac
system is
off, the “sliding car off” icon
will
illuminate steadily. Pressing the
AdvanceTrac
Offcontrol switch
again will turn off the “sliding car
off” icon.
In R (Reverse), ABS and the Engine and Brake Traction Control features
will continue to function; however, ESC is disabled.

Sport Mode
The AdvanceTrac
system provides an available Sport Mode on some
models. This can be selected utilizing the AdvanceTrac off control switch
as shown in the table above.
Sport mode is not intended for use on public roadways as this mode
provides less AdvanceTrac
system intervention than when the default
ESC and Traction Control systems are on. Sport mode will allow more
spirited driving while the AdvanceTrac
system is still enabled.
STEERING
3.5L V6 Engine (SHO):Your vehicle is equipped with an Electric
Power Steering (EPS) system. There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Extreme continuous steering may increase the effort it takes
for you to steer. This occurs to prevent internal overheating and
permanent damage to your steering system. If this should occur, you will
neither lose the ability to steer the vehicle manually nor will it cause
permanent damage. Typical steering and driving maneuvers will allow the
system to cool and steering assist will return to normal.

The EPS system has diagnostic checks that continuously monitor the
EPS system to ensure proper operation. When a system error is
detected, the following message SERVICE POWER STEERING, SERVICE
POWER STEERING NOW or POWER STEERING ASSIST FAULT may
display in the message center, refer to theMessage centerin the
Instrument Clusterchapter for more information.
WARNING:The EPS system has diagnostics checks that
continuously monitor the EPS system to ensure proper operation
of the electronic system. When an electronic error is detected, the
message POWER STEERING ASSIST FAULT will be displayed in the
message center. If this happens, stop the vehicle in a safe place, and
turn off the engine. After at least 10 seconds, reset the system by
restarting the engine, and watch the message center for POWER
STEERING ASSIST FAULT. If the message returns, or returns while
driving, take the vehicle to your dealer to have it checked. With the
message displayed, the steering assist is turned off, making the vehicle
harder to steer.
WARNING:If the message SERVICE POWER STEERING is
displayed in the message center, the EPS system has detected a
problem with the system function. On the next key cycle the message
SERVICE POWER STEERING NOW will be displayed and steering
assist will be removed until the steering system is serviced. Have your
vehicle taken to the nearest dealer as soon as possible.
3.5L,V6 engine:Your vehicle is equipped with a hydraulic steering
system.
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. 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.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If 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.

See your authorized dealer as soon as possible if this procedure
is used.
WARNING:Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
WARNING: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 as soon as possible.
AUTOMATIC TRANSMISSION OPERATION
Automatic Transmission Adaptive Learning
Your transmission is equipped with an adaptive learning strategy found in
the vehicle computer. This feature is designed to increase durability and
provide consistent shift feel over the life of the vehicle. A new vehicle or
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation. Additionally, whenever the battery is
disconnected or a new battery installed, the strategy must be relearned.
Understanding the gearshift positions of the 6–speed automatic
transmission with transmission control switch (if equipped)
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.

D (Drive) with Grade Assist
Pressing the transmission control
switch on the side of the gearshift
lever activates Grade Assist.
Grade Assist
•Improves driving experience in
hilly terrain or mountainous areas
by providing additional grade
(engine) braking and extends
lower gear operation on uphill
climbs.
•Provides additional engine
braking through the automatic
transmission shift strategy which
reacts to vehicle inputs (vehicle
acceleration, accelerator pedal,
brake pedal and vehicle speed).
•Allows the transmission to select
gears that will provide the desired
engine braking based on the
vehicle inputs mentioned above.
This will increase engine RPM during engine braking.
•The grade assist lamp in the
instrument cluster is illuminated.
Grade Assist is designed to provide
optimal gear selection in hilly terrain
or mountainous areas. It is recommended that you return to D (Drive)
on flat terrain to provide the best fuel economy and transmission
function.
To return to O/D (overdrive mode), press the transmission control switch
again.
•The Grade Assist lamp in the instrument cluster will not be
illuminated.
•The transmission will operate in gears one through six.
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.

Understanding the gearshift positions of the 6–speed automatic
transmission with SelectShift Automatic™ transmission (SST)
(if equipped)
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
P (Park)
This position locks the transmission
and prevents the front wheels from
turning.
To put your vehicle in gear:
•Press the brake pedal
•Move the gearshift lever into the
desired gear
To put your vehicle in P (Park):
•Come to a complete stop
•Move the gearshift lever and
securely latch it in P (Park)
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Switch the ignition off and
remove the key whenever you leave your vehicle.
R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R
(Reverse).

Recommended shift speeds
Upshift according to the following chart:
Upshifts when accelerating (recommended for best fuel
economy)
Shift from:
1 - 2 15 mph (24 km/h)
2 - 3 25 mph (40 km/h)
3 - 4 40 mph (64 km/h)
4 - 5 45 mph (72 km/h)
5 - 6 50 mph (80 km/h)
The instrument cluster will show the
current selected gear you are in.
In order to prevent the engine from
running at too low an RPM, which
may cause it to stall, the SST will
automatically make some downshifts
even if it has determined that you
have not downshifted in time.
Although the SST will make some
downshifts for you, it will still allow
you to downshift at any time as long
as the SST determines that the engine will not be damaged from
over-revving.
Engine damage may occur if excessive engine revving is held
without shifting.
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.
WARNING:To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.

The BLIS
and CTA has an yellow
indicator (also referred to as the
alert) located in the left and right
exterior mirrors. When the vehicle is
started, the BLIS
automatically
illuminates both indicators for
several seconds indicating the
system is operating. The first time
you place the transmission in D (Drive) after starting the engine and
drive forward at a speed greater than 3 mph (5 km/h) the BLIS
system
becomes active. Afterwards, the BLIS
remains active for all speeds
including zero mph. BLIS
is also active if the transmission is placed in N
(Neutral). If the transmission is shifted out of D (Drive) or N (Neutral)
the system will enter the CTA mode (see CTA operation below). Once
shifted back in to D (Drive) the BLIS
mode will activate once driven
above 3 mph (5 km/h).
The BLIS
will trigger the alert for vehicles that enter your blind zone
from the rear or merge in to the blind zone from the side. Vehicles that
you pass, or a vehicle that enters the blind zone from the front, will
trigger the alert only after the vehicle is present in the blind zone for
three seconds.Note:For vehicles that pass through the blind zone
quickly, typically less then two seconds, the BLIS
will not illuminate the
alert.
The BLIS
consists of two radar
sensors each located at rearward of
the rear wheel hidden behind the
bumper fascia. Do not place any
type of bumper sticker in this area.
Note:The BLIS
typically will not
detect parked vehicles, humans,
animals, or infrastructure (fences,
guard rails, trees, etc.). The BLIS

does not function when the transmission is in R (Reverse) or P (Park).
The BLIS
does not provide any additional warning when your turn
signal is activated.

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.
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.
