EMISSION CONTROL SYSTEM
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
WARNING: Exhaust leaks may result in entry of harmful and
potentially lethal fumes into the passenger compartment. If you
smell exhaust fumes inside your vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you smell exhaust fumes.
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
• Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
• Have the items listed in Scheduled Maintenance Information
performed according to the specified schedule.
The scheduled maintenance items listed in Scheduled Maintenance
Information are essential to the life and performance of your vehicle
and to its emissions system.
If other than Ford, Motorcraft® or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Illumination of the service engine soon indicator, charging system
warning light or the temperature warning light, fluid leaks, strange odors,
smoke or loss of engine power could indicate that the emission control
system is not working properly.
An improperly operating or damaged exhaust system may allow exhaust
to enter the vehicle. Have a damaged or improperly operating exhaust
system inspected and repaired immediately.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,

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. See On-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 or 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 the
engine is 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.
WARNING: Do not use the tow/haul 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.
Your vehicle has been designed to improve fuel economy by reducing
fuel using 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.
This vehicle is equipped with an Adaptive Transmission Shift Strategy.
The Adaptive Transmission Shift Strategy offers the optimal transmission
operation and shift quality. When the engine is turned off, the shift data
which includes the adaptive information will be stored automatically in
the Powertrain Control Module. If the battery is disconnected for any
reason, the stored information from the last time the key was turned to
off will be read. This way, no information will be lost with any battery
removal or disconnect.

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.
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless the brake pedal is pressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal pressed, it is possible that a fuse has
blown or the vehicle’s brake lamps are not operating properly. Refer to
the Fuses chapter for more information.
If the fuse is not blown and the brake lamps are working properly, the
following procedure will allow you to move the gearshift lever from P
(Park): 1. Apply the parking brake, turn the
ignition key to the off position, and
remove the key.
2. Starting at the rear of the trim
panel, using a screwdriver (or
similar tool) carefully pry up the
trim panel from rear attachments
and disconnect it from the console
to expose the inside of the
gearshift.
3. Locate the brake shift interlock
lever on the passenger side of the
shifter assembly.
4. Apply the brake pedal. Using a
screwdriver (or similar tool), press
and hold the brake shift interlock
lever while pulling the gearshift lever
out of the P (Park) position and into
the N (Neutral) position.
5. Install the trim panel.
6. Apply brake pedal, start the vehicle, and release the parking brake.
See your authorized dealer as soon as possible if this procedure is used.

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.
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.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
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.
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. . 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.

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 them inspected by an authorized dealer. If your vehicle
has continuous vibration or shudder in the steering wheel while braking,
have your vehicle inspected 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 the Vehicle Carechapter for wheel
cleaning instructions.
See theInstrument Cluster chapter for information on the
brake system warning light.
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 your vehicle and
reduce engine power. If you experience this condition, apply the brakes
and bring your vehicle to a safe stop. Turn the engine off, shift to park
(P) and apply the parking brake. Inspect the accelerator pedal and the
area around it for any items or debris that may be obstructing its
movement. If none are found and the condition persists, have your
vehicle towed to the nearest authorized dealer.
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 anti-lock brake 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.

SENSING SYSTEM (IF EQUIPPED)
WARNING:To help avoid personal injury, please read and
understand the limitations of the system as contained in this
section. Sensing is only an aid for some (generally large and fixed)
objects when moving in reverse on a flat surface at parking speeds.
Traffic control systems, inclement weather, air brakes, and external
motors and fans may also affect the function of the sensing system; 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 sensing system.
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 system, may create false beeps.
Note: Keep the sensors (located on the bumper/fascia) free from snow,
ice and large accumulations of dirt. If the sensors are covered, the
system’s accuracy can be affected. Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage to the bumper/fascia, leaving it
misaligned or bent, the sensing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
Note: If your vehicle is equipped with MyKey®, it is possible to prevent
turning the sensing system off. Refer to the MyKey®chapter.
Note: When a trailer is connect to your vehicle, the Rear Sensing System
may detect the trailer and provide warnings. It is suggested that the
driver disables the Rear Sensing System when a trailer is connected to
your vehicle to prevent these warnings.
The sensing system warns the driver of obstacles within a certain range
of the bumper area. The system turns on automatically whenever the
ignition is switched on.

System Sensors
WARNING:Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLIS® as a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLIS® is not a replacement for
careful driving.
Note: It is possible to get a blockage warning with no blockage present;
this is rare and known as a false blockage warning. A false blocked
condition either self-corrects or clears after a key cycle.
The system uses radar sensors
which are located behind the
bumper fascia on each side of the
vehicle. Do not allow these areas to
become obstructed by mud, snow or
bumper stickers, as this can cause
degraded system performance.
If the system detects a degraded performance condition, a blocked
sensor warning or low visibility warning will appear in the information
display and the alert indicator illuminates in the appropriate mirror(s).
The information display warning can be cleared but the alert indicator
remains illuminated.
When the blockage is removed, the system can be reset in two ways: 1)
when at least two objects are detected while driving, or 2) turn the
ignition key from on to off, then back on. If the blockage is still present
after the key cycle, the system senses again that it is blocked after
driving in traffic.

System Errors
If either system senses a problem with the left or right sensor, the
BLIS® indicator in the information display will illuminate and remain on.
Also,BLIND SPOT SYSTEM FAULT orCROSS TRAFFIC SYSTEM
FAULT message will appear. When problems that may cause the left or
right indicator not to illuminate, only the information display message
faults appear.
Switching the Systems Off and On
One or both systems can be switched off temporarily by using the
information display control; refer to the Information Displaychapter.
When you switch off the Blind Spot Information System, you will not
receive alerts and the information display will display a system off
message. The yellow alert indicator in the outside mirror will also flash
twice. The system switches back on whenever you switch the ignition on.
You can also have one or both systems switched off permanently at an
authorized dealer. Once switched off, the system can only be switched
back on at an authorized dealer.
STEERING
Electric Power Steering
WARNING: The electric power steering system has diagnostic
checks that continuously monitor the system to ensure proper
operation. When a system error is detected a steering message will
appear in the information display.
WARNING: The electric power steering system has diagnostic
checks that continuously monitor the system to ensure proper
operation of the electronic system. When an electronic error is
detected, a message will be displayed in the information display. 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 information display for a steering message. If a steering
message returns, or returns while driving, take the vehicle to your
dealer to have it checked.
