engine FORD EXPLORER 2012 5.G Repair Manual

Understanding the gearshift positions of the 6–speed automatic
transmission
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). Turn the ignition to the off
position 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).
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. Refer to D (Drive) with Grade assist or
SelectShift for more information.
D (Drive) with Tow on
The tow feature improves transmission operation when towing a trailer
or a heavy load. All transmission gear ranges are available when using
tow.
Tow can be activated by pressing theTOWswitch located on the
instrument panel by the headlamp control. TheTOW/HAULmessage
will illuminate in the instrument cluster.
The tow feature delays upshifts to reduce frequency of transmission
shifting. Tow also provides engine braking in all forward gears when the
transmission is in the D (Overdrive) position. This engine braking will
slow the vehicle and assist the driver in controlling the vehicle when
descending a grade. Depending on driving conditions and load
conditions, the transmission may downshift, slow the vehicle and control
the vehicle speed when descending a hill, without the accelerator pedal
being pressed. The amount of downshift braking provided will vary based
upon the amount the brake pedal is depressed.
To deactivate the tow feature and return to normal driving mode, press
theTOWbutton. The tow light will no longer be illuminated.
When you shut-off and restart the engine, the transmission will
automatically return to normal D (Overdrive) mode (tow off).
WARNING:Do not use the tow feature when driving in icy or
slippery conditions as the increased engine braking can cause
the rear wheels to slide and the vehicle to swing around with the
possible loss of vehicle control.

D (Drive) with Grade Assist
Pressing the transmission control switch on the side of the gearshift
lever activates grade assist and cancels overdrive.
Grade assist:
•Provides additional grade
(engine) braking and extends
lower gear operation on uphill
climbs for hilly terrain or
mountainous areas.
•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 aid the
driver with optimal gear selection in
hilly terrain or mountainous areas
but is not intended for normal operation. It is recommended that you
return to O/D (overdrive mode) on flat terrain to provide the best fuel
economy and transmission function.
To return to normal D (Drive) position (with O/D), 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.
•Is not intended for use under extended or normal driving conditions
and results in lower fuel economy.

M (Manual)
This vehicle may be equipped with a SelectShift Automatic™
transmission (SST) gearshift lever. SST is an automatic transmission with
the ability for the driver to change gears up or down. By moving the
gearshift lever from D (Drive) to M (Manual), you now have control of
selecting the gear you desire using the toggle switch on the gearshift
lever.
Understanding your SelectShift Automatic™ Transmission (SST)
•To manually downshift the
transmission with the gearshift
lever in M (Manual), press – on
the gearshift lever.
•To manually upshift the
transmission with the gearshift
lever in M (Manual), press + on
the gearshift lever.
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 message center display in 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. 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.

Hill start assist (HSA)
The hill start assist feature makes it easier to pull away when the vehicle
is on a slope without the need to use the parking brake. When the hill
start assist feature is active, the vehicle will remain stationary on the
slope for up to two seconds after you release the brake pedal. During
this time, you have time to move your foot from the brake to the
accelerator pedal and pull away. The brakes are released automatically
once the engine has developed sufficient drive to prevent the vehicle
from rolling down the slope. This is an advantage when pulling away on a
slope; for example from a car park ramp, traffic lights or when reversing
uphill into a parking space.
WARNING:The hill start assist feature does not replace the
parking brake. When you leave the vehicle, always apply the
parking brake and select first or reverse gear.
Using hill start assist
The hill start assist feature is activated automatically when the vehicle is
stopped on a slope greater than five degrees. The hill start assist feature
operates with the vehicle facing downhill if reverse gear is selected. The
hill start assist feature will not operate if the parking brake is activated.
WARNING:You must remain in the vehicle once you have
activated the hill start assist feature.
Activating hill start assist
1. Press the brake pedal to bring the vehicle to a complete standstill.
Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, the hill start assist
feature will be activated automatically.
3. When you remove your foot from the brake pedal, the vehicle will
remain on the slope without rolling away for approximately up to two
seconds. This hold time will automatically be extended if you are in the
process of driving off.
4. Drive off in the normal manner. The brakes will be released
automatically.
WARNING:If the engine is revved excessively, or if a
malfunction is detected when the hill start assist feature is
active, the hill start assist feature will be deactivated.

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.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) gear 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.
WARNING:To help avoid personal injury, always use caution
when in R (Reverse) and when using the RSS.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller
objects, particularly those close to the ground.
WARNING:Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the
normal detection zone of the RSS system may create false beeps.

BLIND SPOT INFORMATION SYSTEM (BLIS) WITH CROSS
TRAFFIC ALERT (CTA) (IF EQUIPPED)
The BLISis a convenience feature
that aids the driver in assessing
whether a vehicle is within an area
on either side of the vehicle
extending rearward from the outside
mirrors to approximately 10 feet
(3 meters) beyond the bumper. This
area is referred to as the blind zone.
The BLISwill alert the driver to
the presence of motorized vehicles
in these areas while driving on roads
and freeways.
The system is not designed to
prevent contact with other vehicles
or objects. The system is designed
to provide a warning to assist the
driver in detecting vehicles in the blind zones. The system will not detect
infrastructure, pedestrians, or cyclists.
WARNING:To help avoid injuries, NEVER use the BLISas a
replacement for using the side and rear view mirrors and looking
over your shoulder before changing lanes. BLISis not a replacement
for careful driving and only an assist.
The BLISand CTA has a yellow
indicator (also referred to as the
alert) located in the left and right
exterior mirrors. When the vehicle is
started, the BLISautomatically
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 BLISsystem
becomes active. Afterwards, the BLISremains active for all speeds
including zero mph. BLISis 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 into D (Drive) the BLISmode will activate once driven
above 3 mph (5 km/h).

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.
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.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Emergency maneuvers
WARNING: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 are not 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.
•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,
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.

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.
“Tread Lightly” is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest Service and the Bureau of Land
Management in encouraging you to help preserve our national forest and
other public and private lands by “treading lightly.”
Driving on hilly or sloping terrain
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down.Note:Avoid driving crosswise or turning on steep
slopes or hills. A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.
When climbing a steep slope or hill,
start in a lower gear rather than
downshifting to a lower gear from a
higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of stalling.
If you do stall out, Do not try to
turnaround because you might roll
over. It is better to back down to a
safe location.
Apply just enough power to the wheels to climb the hill. Too much
power will cause the tires to slip, spin or lose traction, resulting in loss of
vehicle control.

Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, avoid locking of the wheels. Use
a “squeeze” technique, push on the brake pedal with a steadily increasing
force which allows the wheels to brake yet continue to roll so that you
may steer in the direction you want to travel. If you lock the wheels,
release the brake pedal and repeat the squeeze technique. Since your
vehicle is equipped with a Four Wheel Anti-Lock Brake System (ABS),
apply the brake steadily. Do not “pump” the brakes. Refer toBrakesin
this chapter for additional information on the operation of the anti-lock
brake system.
Maintenance and modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
TERRAIN MANAGEMENT (IF EQUIPPED)
Terrain management adapts the responses of the vehicle’s engine,
transmission, 4WD system, suspension, and stability control systems to
match the demands of the terrain. The system optimizes drivability and
comfort as well as maximizing traction.
