TIRE PRESSURE MONITORING SYSTEM (TPMS) (IF EQUIPPED)
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator
to indicate when the system is not operating properly. The TPMS
malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously illuminated.
This sequence will continue upon subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be
able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
The tire pressure monitoring system complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the

8. Remove the valve cap from the valve stem on the right rear tire.
Decrease the air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire.
Decrease the air pressure until the horn sounds.
Training is complete after the horn sounds for the last tire trained
(driver’s side rear tire), the TPMS tell tale stops flashing, and the
message center displays:
TRAINING COMPLETE.
10. Turn the ignition off. If two short horn beeps are heard, the reset
procedure was unsuccessful and must be repeated.
If after repeating the procedure and two short beeps are heard when the
ignition is turned to off, seek assistance from your authorized dealer.
11. Set all four tires to the recommended air pressure as indicated on
the Safety Compliance Certification Label or Tire Label located on the
B-Pillar or the edge of the driver’s door. SeeVehicle loading - with and
without a trailerin this chapter for more information.
SNOW TIRES AND CHAINS
WARNING:Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and
performance of your vehicle, which could result in an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
Additionally, the use of non-recommended tires and wheels could
cause steering, suspension, axle or transfer case/power transfer unit
failure.
Note:Do not use snow chains on vehicles with 20 inch wheels and tires.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.

•The TBC interacts with the brake system of the vehicle, including
ABS, in order to reduce the likelihood of trailer wheel lockup.
Therefore, if these systems are not functioning properly the TBC may
not function at full performance.
•When the vehicle is turned off, the TBC Output is disabled and the
display is shut down. Reactivation of the ignition from off to on will
awaken the TBC module.
•The TBC is only a factory or dealer installed item. Ford is not
responsible for warranty or performance of the TBC due to misuse or
customer installation.
•Do not attempt removal of the TBC without consulting the
Workshop Manual.Damage to the unit may result.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking-up trailer lamps.
Driving while you tow
When towing a trailer:
•Consult your local motor vehicle laws for towing a trailer.
•Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 km) of trailer towing and don’t make full-throttle starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Activate the tow/haul feature to eliminate excessive transmission
shifting and assist in transmission cooling. For additional information,
refer toAutomatic transmission operationin theDrivingchapter.
•Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
•Your vehicle may be equipped with a temporary or conventional spare
tire. If the spare tire is different in size (diameter and/or width), tread
type (All-Season or All-Terrain) or is from a different manufacturer
other than the road tires on your vehicle, your spare tire is considered
“temporary”. Consult information on the Tire Label or Safety
Compliance Certification Label for limitations when using.

Braking
•Anticipate the need to stop; allow much more distance and time to
stop than normal.
•Do not apply the trailer brakes for extended periods of time as they
can overheat and lose effectiveness.
•The trailer brakes must be inspected and serviced at intervals
specified by the manufacturer. This includes the shoes, drum and
trailer brake magnets.
•Electric brakes also require periodic adjustment to keep the shoes
properly spaced. If the brakes get hot when driving or if they will not
hold, chances are that they need adjustment.
Backing-up
•Practice backing-up, particularly if you are a novice. Turn the steering
wheel to the right to move the trailer’s rear end to the right.
•Sharp steering movements may cause the trailer to jackknife or go out
of control.
Tires
•Select tires that meet the trailer loading requirements.
•All trailer tires should be of the same size, and construction.
•Always check tow vehicle and trailer tire pressure before towing.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•Do not allow the static water level to rise above the bottom edge of
the rear bumper.
•Do not allow waves to break higher than 6 in (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
•Causing internal damage to the components.
•Affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.

WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracwith RSCsystem. In addition, installing any
stereo loudspeakers may interfere with and adversely affect the
AdvanceTracwith RSCsystem. Install any aftermarket stereo
loudspeaker as far as possible from the front center console, the
tunnel, and the front seats in order to minimize the risk of interfering
with the AdvanceTracwith RSCsensors. Reducing the effectiveness
of the AdvanceTracwith RSCsystem could lead to an increased risk
of loss of vehicle control, vehicle rollover, personal injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracwith RSCsystem is an indication that
at least some of the tires have exceeded their ability to grip the road;
this could reduce the operator’s ability to control the vehicle,
potentially resulting in a loss of vehicle control, vehicle rollover,
personal injury and death. If your AdvanceTracwith RSCsystem
activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTracwith RSCsystem, the stability control light will
illuminate steadily. Verify that the AdvanceTracwith RSCsystem is
not manually disabled. Press the stability control button located on the
instrument panel to the right of the climate control system. If the
stability control light still illuminates steadily, have the system serviced
by an authorized dealer immediately. Operating your vehicle with
AdvanceTracwith RSCdisabled could lead to an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
The AdvanceTracwith RSCsystem automatically enables each time
the engine is started. All features of the AdvanceTracwith RSCsystem
(TCS, ESC, and RSC) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.

For routine cleaning, wipe the surface with a soft, damp cloth. For more
thorough cleaning, wipe the surface with a mild soap and water solution.
•Clean spills as quickly as possible.
•Test any cleaner or stain remover on an inconspicuous part of the
leather as cleaners may darken the leather.
•Do not spill coffee, ketchup, mustard, orange juice or oil-based
products on the leather as they may permanently stain the leather.
•Do not use household cleaning products, alcohol solutions, solvents or
cleaners intended for rubber, vinyl or plastics.
Scratches
Natural Markings - Because the leather in the seat comes from genuine
steer hides, there will be evidence of naturally occurring markings, such
as small scars. These markings give character to the seating covers and
should be considered as proof of a genuine leather product.
In order to lessen the appearance of certain scratches and other wear
marks, apply conditioner on the affected area following the same
instructions as in theConditioningsection.
Conditioning
Bottles of King RanchLeather Conditioner are available at the King
RanchSaddle Shop. Visit the website atwww.krsaddleshop.com,or
telephone (in the United States) 1–800–282–KING (5464). If you are
unable to obtain King RanchLeather Conditioner, use another premium
leather conditioner.
•Clean the surfaces using the steps outlined in theCleaningsection.
•Ensure the leather is dry then apply a nickel-sized amount of
conditioner to a clean, dry cloth.
•Rub the conditioner into leather until it disappears. Allow the
conditioner to dry and repeat the process for the entire interior. If a
film appears, wipe off film with a dry, clean cloth.
UNDERBODY
Flush the complete underside of your vehicle frequently. Keep body and
door drain holes free from packed dirt.
Note:Use care when using a power washer to clean the driveline,
especially the driveshaft and interfacing components. The high-pressure
fluid could penetrate the sealed parts and cause damage.
