an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine ’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician 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. Your 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 closed properly. See Refueling (page 171).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions 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 you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
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 and
Maintenance (I/M) Testing
Some state and 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, your vehicle may need
service. See On-Board Diagnostics.
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 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
176
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Fuel and Refueling

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 your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving:
1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.

AUTOMATIC TRANSMISSION
WARNINGS
Always set the parking brake fully
and make sure you shift the gearshift
lever to park (P). Switch the ignition
off and remove the key whenever you leave
your vehicle. Do not apply the brake pedal and
accelerator pedal simultaneously.
Applying both pedals simultaneously
for more than a few seconds will limit
engine rpm, which may result in difficulty
maintaining speed in traffic and could lead
to serious injury. Understanding the Positions of
Your Automatic Transmission
Putting your vehicle in gear:
1. Fully press down the brake pedal.
2.
Press and hold the button on the front
of the gearshift lever.
3. Move the gearshift lever into the desired gear.
4. Release the button and your transmission will remain in the selected
gear. Park (P)
This position locks the transmission and
prevents the wheels from turning.
Reverse (R)
With the gearshift lever in reverse (R), your
vehicle will move backward. Always come
to a complete stop before shifting into and
out of reverse (R).
Neutral (N)
With the gearshift lever in neutral (N), your
vehicle can be started and is free to roll.
Hold the brake pedal down while in this
position.
Drive (D)
Drive (D) is the normal driving position for
the best fuel economy. The overdrive
function allows automatic upshifts and
downshifts through gears one through six.
Sport (S)
Moving the gearshift lever to sport (S):
•
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.
• Gears are selected more quickly and
at higher engine speeds.
SelectShift Automatic ™
Transmission
Your vehicle is equipped with a SelectShift
Automatic transmission. The SelectShift
Automatic transmission gives you the
ability to change gears up or down
(without a clutch) as desired.
178
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing TransmissionPRNDS
E142628

In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift still automatically makes
some downshifts if it has determined that
you have not downshifted in time.
Although SelectShift makes some
downshifts for you, it still allows you to
downshift at any time as long as the
SelectShift determines that damage will
not be caused to the engine from
over-revving.
Note:
Engine damage may occur if you
maintain excessive engine revving without
shifting.
SelectShift does not automatically upshift,
even if the engine is approaching the RPM
limit. It must be shifted manually by
pressing the + button. Notice should be
taken of the shift indicator lamp, which
alerts you when to shift to make sure you
achieve the highest level or efficiency and
fuel economy.
Pull the + paddle on the steering wheel
to activate SelectShift.
• Pull the right paddle (+) to upshift.
• Pull the left paddle (–) to downshift. SelectShift in drive (D):
•
Provides a temporary manual mode
for performing more demanding
maneuvers where extra control of gear
selection is required (for example,
when towing or overtaking). This mode
will hold a selected gear for a
temporary period of time dependent
on driver inputs (for example, steering
or accelerator pedal input).
SelectShift in sport (S):
• Provides a permanent manual gear
selection where full control of gear
selection is required.
To exit SelectShift mode shift the
transmission into another gear (for
example, drive [D]).
The instrument cluster displays your
currently selected gear. If a gear is
requested but not available due to vehicle
conditions (low speed, too high engine
speed for requested gear selection), the
current gear will flash three times.
Note: At full accelerator pedal travel, the
transmission automatically downshifts for
maximum performance.
Brake-Shift Interlock WARNINGS
Do not drive your vehicle until you
verify that the brake lamps are
working.
When doing this procedure, you need
to take the transmission out of park
(P) which means your vehicle can
roll freely. To avoid unwanted vehicle
movement, always fully set the parking
brake prior to doing this procedure. Use
wheels chocks if appropriate. If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. Have your vehicle
checked as soon as possible. 179
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing TransmissionE144821

Use the brake shift interlock lever to move
the gearshift lever from the park position
in the event of an electrical malfunction or
if your vehicle has a dead battery.
Apply the parking brake and turn the
ignition off before performing this
procedure.
1. Insert a screwdriver (or similar tool)
between the shifter bezel and the top
finish panel.
2. Use the tool to unsnap the shifter bezel
from the finish panel. 3. Locate the white lever located on the
left side of the shifter.
4. Using the tool move the white lever towards the front of the shifter.
5. While holding the white lever in the forward position, move the shifter from
the park position. 6.
Press the shifter bezel back into the top
finish panel until it snaps back into
position.
7. Apply the brake pedal, start the vehicle
and release the parking brake.
Note: See your authorized dealer as soon
as possible if this procedure is used.
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.

PRINCIPLE OF OPERATION
This system is a proactive system. It has
the ability to anticipate wheel slip and
transfer torque to the rear wheels before
slip occurs. Even when wheel slip is not
present, the system is continuously making
adjustments to the torque distribution, in
an attempt to improve straight line and
cornering behavior, both on and off road.
The system automatically turns on every
time you switch the ignition on.
If any component requires maintenance,
a message appears in the information
display.
USING FOUR-WHEEL DRIVE
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. The intelligent 4WD system continuously
monitors vehicle conditions and
automatically adjusts the power
distribution between the front and rear
wheels. It combines transparent
all-surface operation with highly capable
four-wheel drive. The 4WD system is always active and
requires no driver input. It is capable of
handling all road conditions, including
street and highway driving as well as
off-road and winter driving. The driver can
optimize more 4WD control by moving the
terrain management switch for the correct
terrain. See Using Terrain Response
(page 192).
Note: A warning message will be displayed
in the information display when an 4WD
system fault is present
See Information
Messages (page 113). An 4WD system fault
will cause the 4WD system to default to
front-wheel drive only mode. When this
warning message is displayed, have your
vehicle serviced at an authorized dealer
Note: A warning message will be displayed
in the information display if the 4WD system
has overheated
See Information
Messages (page 113). This condition may
occur if the vehicle was operated in extreme
conditions with excessive wheel slip, such
as deep sand. To resume normal 4WD
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 4WD
system has adequately cooled, the warning
message will turn off and normal 4WD
function will return.
Do not use a spare tire of a different size
other than the tire provided. If the
mini-spare tire is installed, the 4WD system
may disable automatically and enter
front-wheel drive only mode to protect
driveline components. This condition will
be indicated by a warning in the
information display
See Information
Messages (page 113). If there is a warning
message in the information display 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
181

(If Equipped)

WARNINGS
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. 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 few minutes 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.
If your vehicle is equipped with
AdvanceTrac® with Roll Stability
Control ™, it may be beneficial to
disengage the AdvanceTrac® with Roll
Stability Control ™ system while
attempting to rock the vehicle.
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, 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.
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.
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
Note: Driving through deep water may
damage your vehicle.
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.
183
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Four-Wheel Drive
(If Equipped)

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 4WD 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.
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
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. 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.
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 turn around
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.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating.
Do not descend in neutral; instead,
disengage overdrive or manually shift to a
lower gear. When descending a steep hill,
avoid sudden hard braking as you could
lose control. The front wheels have to be
turning in order to steer the vehicle.
Your vehicle has anti-lock brakes, therefore
apply the brakes steadily. Do not
“pump”
the brakes.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Alloy
Wheels (page 302).
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
may flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop. See
Warning Lamps and
Indicators (page 94).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer. Brake Assist
Brake assist detects when you brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can reduce stopping
distances in critical situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
This lamp momentarily
illuminates when you turn the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the system may be disabled. Have
the system checked by an authorized
dealer. If the anti-lock brake system is
disabled, normal braking is still effective. If the brake warning lamp
illuminates when you release the
parking brake, have the system
checked by an authorized dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note: When the system is operating, the
brake pedal may pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.
The anti-lock braking system will not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.

PARKING BRAKE
WARNING
Always set the parking brake fully
and make sure the transmission is
locked in park (P). Failure to set the
parking brake and engage park could result
in vehicle roll-away, property damage or
bodily injury. To set the parking brake, press the parking
brake pedal down to its fullest extent. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released.
To release the parking brake, press the
parking brake pedal down again.
If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and
hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.
HILL START ASSIST
WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking
brake. Failure to leave your vehicle securely
parked may lead to a crash or injury. See
Parking Brake (page 187). WARNINGS
You must remain in your vehicle
when the system turns on. At all
times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required. Failure
to take care may result in the loss of
control of your vehicle, serious personal
injury or death. The system will turn off if a
malfunction is apparent or if you rev
the engine excessively. Failure to
take care may result in the loss of control
of your vehicle, serious personal injury or
death. The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has
developed sufficient torque to prevent your
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.
Note:
The system only functions when you
bring your vehicle to a complete standstill
in an uphill gear (for example, drive (D)
when facing uphill or reverse (R) when
facing downhill).
Note: There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep
the brake pedal pressed.
