On-board Diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet government
emission standards. The OBD-II system also assists your authorized
dealer in properly servicing your vehicle.
When the service engine soon indicator illuminates, the OBD-II
system has detected a malfunction. Temporary malfunctions
may cause the service engine soon indicator to illuminate.
Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel fill inlet may not have been properly closed. SeeEasy Fuel
“no cap” fuel systemin this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly closing the fuel fill inlet or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the service engine soon indicator
should stay off the next time the engine is started. A driving cycle
consists of a cold engine startup followed by mixed city/highway driving.
No additional vehicle service is required.
If the service engine soon indicator remains on, have your vehicle
serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with the service engine soon indicator on can result in
increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and lead to more costly repairs.

Readiness for Inspection/Maintenance (I/M) Testing
Some state/provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration.
If the service engine soon indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer toOn-board
diagnostics (OBD-II)in this chapter.
Your vehicle may not pass the I/M test if the service engine soon
indicator is on or not working properly (bulb is burned out), or if the
OBD-II system has determined that some of the emission control systems
have not been properly checked. In this case, the vehicle is considered
not ready for I/M testing.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the service engine soon
indicator blinks eight times, it means that the vehicle is not ready for I/M
testing; if the service engine soon indicator stays on solid, it means that
the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.

AUTOMATIC TRANSMISSION
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.
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)
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).
N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
D (Drive) with overdrive
The normal driving position for the best fuel economy. Transmission
operates in gears one through six. The automatic transmission shift
strategy has the ability to detect hilly terrain or mountainous areas and
will provide a limited amount of grade assist features automatically.

S (Sport)
Moving the gearshift lever to S (Sport):
•Provides additional grade (engine) braking and extends lower gear
operation to enhance performance for uphill climbs, hilly terrain or
mountainous areas. This will increase engine RPM during engine
braking.
•Provides additional lower gear operation through the automatic
transmission shift strategy which reacts to vehicle inputs (vehicle
acceleration, accelerator pedal, brake pedal and vehicle speed).
•Gears are selected more quickly and at higher engine speeds.
Note:The system will stay in S (Sport) until the gear shift lever is
moved into another gear for example P (park) or D (Drive).
SelectShift Automatic™ Transmission (if equipped)
Note:Your transmission must be in S (Sport) for SelectShift to operate
properly.
Your SelectShift automatic transmission gives you the ability to manually
change gears if you’d like. To use SelectShift, move the gearshift lever
into S (Sport). Now you can use select shift to manually changer gears.
If your vehicle is equipped with the +/– buttons on the side of your
gearshift lever:
•Press (–) on the gearshift lever
button to manually downshift the
transmission.
•Press (+) on the gearshift lever
button to manually upshift the
transmission.

If your vehicle is equipped with paddles on the steering wheel:
•Pull the left paddle(–)to
downshift the transmission.
•Pull the right paddle (+) to upshift
the transmission.
Upshift to the recommended shift speeds 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 selected gear you are currently in.
In order to prevent the engine from running at too low an RPM, which
may cause it to stall, SelectShift will automatically make some downshifts
if it has determined that you have not downshifted in time. It will still
allow you to downshift at any time as long as SelectShift determines that
the engine will not be damaged from over-revving.
Note:If manual control is no longer desired, you must return gear shift
lever from S (Sport) to D (Drive).
Note:Engine damage may occur if excessive engine revving is held
without shifting.

3. Insert the screwdriver (or similar
tool) into the access hole and press
while pulling the gearshift lever out of
the P (Park) position and into the N
(Neutral) position.
4. Remove the tool and reinstall the
protective cover.
5. Start the vehicle and release the
parking brake.
Automatic transmission adaptive learning
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.
If Your Vehicle Gets Stuck in Mud or Snow
Note:Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note:Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
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.

Using your All Wheel Drive (AWD) system
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 vehicles cannot. The AWD system is active
all the time and requires no input from the operator.
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.
Note:When an AWD system fault is present, the warning Check AWD
will display in the message center. The AWD system is not functioning
correctly and defaulted to front-wheel drive. When this warning is
displayed, have your vehicle serviced at an authorized dealer.
Note:The AWD Off message may also be displayed in the message
center if the AWD system has overheated and defaulted to front-wheel
drive. This condition may occur if the vehicle was operated in extreme
conditions with excessive wheel slip, such as deep sand. To resume
normal AWD function as soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10 minutes. After the engine has
been restarted and the AWD system has adequately cooled, the AWD Off
message will turn off and normal AWD function will return. The AWD Off
message will turn off when the system cools and normal AWD function
returns.
The Power Transfer Unit (PTU) in Taurus SHO™ vehicles does not
require any normal scheduled maintenance. The system is electronically
monitored and notifies the driver of required service by displaying the
message Change AWD/4WD Power Transfer Unit Lube in the information
display. The PTU lube will be more likely to require a fluid change if the
vehicle has experienced extended periods of extreme/severe duty cycle
driving. Do not check or change the PTU lubricant unless the unit has
been submerged in water, shows signs of leakage or a message indicating
required service is displayed. Contact your authorized dealer for service
and to reset the PTU lube life monitor.”
If your vehicle is equipped with AWD, a spare tire of a different size
other than the tire provided should never be used. If the mini-spare tire
is installed, the AWD system may disable automatically and enter
front-wheel drive only mode to protect driveline components. This
All-Wheel Drive197

condition may be indicated by an AWD Off message in the information
display. If there is an AWD Off message in the message center from using
the spare tire, this indicator should turn off after reinstalling the repaired
or replaced normal road tire and cycling the ignition off and on. It is
recommended to reinstall the repaired or replaced road tire as soon as
possible. Major dissimilar tire sizes between the front and rear axles
could cause the AWD system to stop functioning and default to
front-wheel drive or damage the AWD system.
DRIVING IN SPECIAL CONDITIONS WITH AWD
AWD vehicles are 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 in deep sand under high outside
temperatures, use a low gear when possible. Lower 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 in Special Conditions
•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.
