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.

USING YOUR FOUR WHEEL DRIVE (4WD) SYSTEM
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 theTerrain Managementchapter for more
information.
Note:When an 4WD system fault is present, the warning Check 4WD
will display in the message center. The 4WD system is not functioning
correctly and will default to front-wheel drive. When this warning is
displayed, have your vehicle serviced at an authorized dealer.
Note:The 4WD Off message may also be displayed in the message
center if the 4WD 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 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 4WD Off
message will turn off and normal 4WD function will return. The 4WD Off
message will turn off when the system cools and normal 4WD function
returns.
If your vehicle is equipped with 4WD, a spare tire of a different size
other than the tire provided should never be used. 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 may be indicated by an 4WD Off message in the information
display. If there is an 4WD 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 4WD system to stop functioning and default to
front-wheel drive or damage the 4WD system.

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.
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. A
danger lies in losing traction, slipping sideways and possibly rolling over.
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. 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.

Anti-lock Brake System (ABS)
This system helps you maintain steering control during emergency stops
by keeping the brakes from locking.
The ABS lamp momentarily illuminates when the ignition is
turned on. If the light does not illuminate during start up,
remains on or flashes, the ABS may be disabled and may need
to be serviced.
If the ABS is disabled, normal braking is still effective. If the
brake warning lamp illuminates with the parking brake released,
have your brake system serviced immediately.
HINTS ON DRIVING WITH ANTI-LOCK BRAKES
When the system is operating, the brake pedal will pulse and may travel
further. Maintain pressure on the brake pedal. You may also hear a noise
from the system. This is normal.
The ABS will not eliminate the dangers inherent 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: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.
WARNING:Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park).
To set the parking brake, press the parking brake pedal down to its
fullest extent.
To release the parking brake, press the parking brake pedal down again.

PRINCIPLES OF OPERATION
The traction control system helps avoid drive wheel spin and loss of
traction.
If your vehicle begins to slide, the system applies the brakes to individual
wheels and, when needed, reduces engine power at the same time. If the
wheels spin when accelerating on slippery or loose surfaces, the system
reduces engine power in order to increase traction.
USING TRACTION CONTROL
In certain situations (e.g. stuck in snow or mud), turning the traction
control off may be beneficial as this allows the wheels to spin with full
engine power. Turn off the traction control system using the information
display control. Refer to theInformation Displayschapter.
System indicator lights and messages
WARNING:If a failure has been detected within the Traction
Control System, the stability control light will illuminate steadily.
Verify that the Traction Control System was not manually disabled using
the information display control. If the stability control light still
illuminates steadily, have the system serviced by an authorized dealer
immediately. Operating your vehicle with Traction Control disabled
could lead to an increased risk of loss of vehicle control, vehicle
rollover, personal injury and death.
The stability control light temporarily illuminates on engine
start-up and flashes when a driving condition activates the
stability system.
The stability control off light temporarily illuminates on engine
start-up and stays on when the traction control system is
turned off or if a problem occurs in the stability system.
When the traction control system is turned off or on, a message appears
in the information display showing system status.

If the system becomes inoperable, selecting some modes may not be
possible and a message is displayed. If it becomes inoperable due to a
system malfunction, all of the mode indicators on the control turn off and
one of the following messages appears in the information display:
TERRAIN MANAGEMENT SYSTEM FAULT:Cycling the key may
clear the fault. If key cycling does not work, have the system serviced by
an authorized dealer.
MODE CHANGE NOT ACCEPTED, RETRY:A mode change cannot
be made at the time of driver request. Try the mode change again.
HILL DESCENT CONTROL™ (if equipped)
WARNING:Hill descent control cannot control descent in all
surface conditions and circumstances, such as ice or extremely
steep grades. Hill descent control is a driver assist system and cannot
substitute for good judgment by the driver. Failure to do so may result
in loss of vehicle control, crash or serious injury.
WARNING:Hill descent control does not provide hill hold at
zero mph (0 km/h). When stopped, the parking brake must be
applied and/or the vehicle must be placed in P (Park) or it may roll
away.
Hill descent control allows the driver to set and maintain vehicle speed
while descending steep grades in various surface conditions.
Hill descent control can maintain vehicle speeds on downhill grades
between 3 mph (5 km/h) and 20 mph (32 km/h). Above 20 mph
(32 km/h), the system remains armed, but descent speed cannot be set
or maintained.
Hill descent control requires a cooling down interval after a period of
sustained use. The amount of time that the feature can remain active
before cooling varies with conditions. The system will provide a warning
in the message center and a chime will sound when the system is about
to disengage for cooling. At this time, manually apply the brakes as
needed to maintain descent speed.
