5. Repeat this procedure for each tire, including the spare.
Note:Some spare tires operate at a higher inflation pressure than the
other tires. For T-type/mini-spare tires (seeT-Type/Mini-Spare Tire
Informationsection for description): Store and maintain at 60psi (4.15
bars). For Full Size and Dissimilar spare tires (seeDissimilar Spare
Tire/Wheel Informationsection for description): Store and maintain at
the higher of the front and rear inflation pressure as shown on the Safety
Compliance Certification Label.
6. Visually inspect the tires to make sure there are no nails or other
objects embedded that could poke a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts or bulges.
TIRE REPLACEMENT REQUIREMENTS
Your vehicle is equipped with tires designed to provide a safe ride and
handling capability.
Only use replacement tires and wheels that are the same size
and type (such as P-metric versus LT-metric or all-season versus
all-terrain) as those originally provided by Ford Motor Company. Use of
any tire or wheel not recommended by Ford Motor Company 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. If you have questions regarding tire replacement, see an
authorized dealer.
Make sure all tires and wheels on the vehicle are of the same size, type,
tread design, brand, load-carrying capacity and speed rating because it
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.
The tire pressure monitoring sensors mounted in the wheels (originally
installed on your vehicle) are not designed to be used in after-market
wheels.
The installation of replacement tires with steel cord body plies in the tire
sidewall may cause malfunction of the Tire Pressure Monitoring System
(TPMS), and is not recommended (cord material information is molded
on the tire sidewall). Additionally, if your vehicle was originally equipped

Safety practices
Driving habits have a great deal to do with your tire mileage and safety.
•Observe posted speed limits
•Avoid fast starts, stops and turns
•Avoid potholes and objects on the road
•Do not run over curbs or hit the tire against a curb when parking
If your vehicle is stuck in snow, mud, sand, etc.,do notrapidly
spin the tires; spinning the tires can tear the tire and cause an
explosion. A tire can explode in as little as three to five seconds.
Never spin the tires in excess of the 35 mph (55 km/h) point
indicated on the speedometer.
Highway hazards
No matter how carefully you drive there’s always the possibility that you
may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove wheel and replace it with your spare tire and wheel. If
you cannot detect a cause, have the vehicle towed to the nearest repair
facility or tire dealer to have the vehicle inspected.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you’re driving, the wheels may be
out of alignment. Have an authorized dealer check the wheel alignment
periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by an authorized dealer.
Front wheel drive (FWD) vehicles and those with an independent rear
suspension (if equipped) may require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.

Weight distributing 4060 (8950) 406 (895)
These are hitch ratings only; actual vehicle ratings are dependent on
engine, transmission and axle combinations.
Towing trailers beyond the maximum tongue weight exceeds the
limit of the towing system and could result in vehicle structural
damage, loss of vehicle control and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your authorized dealer or a
reliable trailer dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle’s bumper or attach to the
axle. You must distribute the load in your trailer so that 10%–15% of the
total weight of the trailer is on the tongue.
Load equalizing hitch
When hooking up a trailer using a load equalizing hitch, always use the
following procedure:
1. Park the unloaded vehicle on a level surface. With the ignition in the
ON position, apply the brake and place the gearshift lever in
(Overdrive) for 10 seconds, then return the gearshift lever to P (Park)
and release the brake. With the ignition still in the ON position, and all
doors closed, allow the vehicle to stand (without passengers) for several
minutes so that it can level.
2. Turn the air suspension (if equipped) control to OFF.
3. Measure the height of a reference point on the front and rear bumpers
at the center of the vehicle.
4. Attach the trailer to the vehicle and adjust the hitch equalizers so that
the front bumper height is within a
12” (13 mm) of the reference point.
After proper adjustment, the rear bumper should be no higher than in
Step 3.

5. Turn the air suspension (if equipped) control to ON.
Note:Adjusting an equalizing hitch so the rear bumper of the vehicle is
higher than it was unloaded will defeat the function of the load
equalizing hitch and may cause unpredictable handling.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. See 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:
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to

Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac
with RSC performs a system self-check. During
AdvanceTrac
with RSC system operation you may experience the
following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•The AdvanceTrac
with RSC indicator light will flash
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTrac
with RSC
operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac
with Roll Stability Controlsystem. Also, do
not install a stereo loudspeaker near the front center console or
under either front seat. The speaker vibrations can adversely
affect the AdvanceTrac
with Roll Stability Controlsensors
located in this area.
Note:Pressing the AdvanceTrac
with RSC button will disable the
AdvanceTrac
with RSC system.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an AdvanceTrac
with
Roll Stability Controlevent is an indication that at least some of the
tires have exceeded their ability to grip the road; this may lead to an
increased risk of loss of vehicle control, vehicle rollover, personal injury
and death. If you experience a severe road event, SLOW DOWN.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.

•Do not operate the vehicle with the power steering pump fluid level
below the MIN mark on the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride comfort, vehicle
handling and general vehicle performance by adjusting the vehicle’s ride
height according to vehicle speed, weight added to or removed from the
vehicle and four-wheel drive (if equipped) operation. Normal vehicle
operation does not require any action by the driver.
When you enter the vehicle and the ignition is off, the air suspension will
have automatically lowered the vehicle to its lowest height to provide
easier entry. When a door or the liftgate is opened, the system
memorizes and maintains that height until either all doors are closed or
the vehicle’s speed exceeds 15 mph (24 km/h). The air suspension
system will then raise the vehicle’s height to its normal position when the
ignition is turned on, all doors are closed and the transmission is shifted
from P (Park).
When the vehicle is in motion, the air suspension will adjust the vehicle
ride height to normal operating position to maximize your ride comfort.
If your vehicle is equipped with four-wheel drive and you shift into 4WD
LOW, the air suspension will not move to it’s lowest position; instead, the
ride height is raised above the normal ride height position (at speeds
below 35 mph [56 km/h]) to improve ground clearance.
If a load is added to, or removed from the vehicle, the load leveling
feature of the air suspension system will adjust the suspension to keep
the vehicle at a constant level.
When exiting the vehicle, the air suspension will automatically lower the
vehicle to its lowest height to provide easier exit. You may hear a buzz or
click from the air suspension system when the ignition is turned off. The
