any tire is under-inflated, carefully drive the vehicle to the nearest
location where air can be added to the tires. Inflate all the tires to the
recommended inflation pressure.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
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.
Follow these guidelines when using snow tires and chains:
•Use only cable type chains or chains offered by Ford as an accessory
or equivalent. Other conventional link type chains may contact and
cause damage to the vehicle’s wheel house and/or body.
•Do not install chains on the front wheels. Chains on the front wheels
may interfere with suspension components.
•Chains are not recommended for use on the P275/55R20 tire.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
•The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
•Do not exceed 30 mph (48 km/h) with tire chains on your vehicle.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading

GCW (Gross Combined Weight)– is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.
GCWR (Gross Combined Weight Rating)– is the maximum allowable
weight of the vehicle and the loaded trailer – including all cargo and
passengers – that the vehicle can handle without risking damage.
(Important: The towing vehicle’s braking system is rated for operation at
GVWR, not at GCWR.) Separate functional brakes should be used for
safe control of towed vehicles and for trailers where the GCW of the
towing vehicle plus the trailer exceed the GVWR of the towing vehicle.
The GCW must never exceed the GCWR.
Maximum Loaded Trailer Weight– is the highest possible weight of a
fully loaded trailer the vehicle can tow. It assumes a vehicle with only
mandatory options, no cargo (internal or external), a tongue load of
10–15% (conventional trailer) or king pin weight of 15–25% (fifth wheel
trailer), and driver only (150 lb. [68 kg]).Consult your authorized
dealer (or theRV and Trailer Towing Guideprovided by your
authorized dealer) for more detailed information.
Tongue Load or Fifth Wheel King Pin Weight– refers to the amount
of the weight that a trailer pushes down on a trailer hitch.
Examples:For a 5,000 lb. (2,268 kg) conventional trailer, multiply 5,000
by 0.10 and 0.15 to obtain a proper tongue load range of 500 to 750 lb.
(227 to 340 kg). For an 11,500 lb. (5,216 kg) fifth wheel trailer, multiply
by 0.15 and 0.25 to obtain a proper king pin load range of 1,725 to 2,875
lb. (782 to 1,304 kg)
Do not exceed the GVWR or the GAWR specified on the Safety
Compliance Certification Label.

•A final example for your vehicle with 1400 lb. (635 kg) of cargo and
luggage capacity. You and one of your friends decide to pick up
cement from the local home improvement store to finish that patio
you have been planning for the past 2 years. Measuring the inside of
the vehicle with the rear seat folded down, you have room for 12-100
lb. (45 kg) bags of cement. Do you have enough load capacity to
transport the cement to your home? If you and your friend each weigh
220 lb. (99 kg), the calculation would be: 1400 – (2 x 220) –
(12 x 100) = 1400 – 440 – 1200 = – 240 lb. No, you do not have
enough cargo capacity to carry that much weight. In metric units, the
calculation would be: 635 kg — (2 x 99 kg) — (12 x 45 kg) = 635 —
198 — 540 = —103 kg. You will need to reduce the load weight by at
least 240 lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags,
then the load calculation would be:
1400 – (2 x 220) – (9 x 100) = 1400 – 440 – 900 = 60 lb. Now you
have the load capacity to transport the cement and your friend home.
In metric units, the calculation would be: 635 kg — (2 x 99 kg) —
(9 x 45 kg) = 635 — 198 — 405 = 32 kg.
The above calculations also assume that the loads are positioned in your
vehicle in a manner that does not overload the Front or the Rear Gross
Axle Weight Rating specified for your vehicle on the Safety Compliance
Certification Label found on the edge of the driver’s door.
Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see thePreparing to drive your vehiclesection in
theDrivingchapter of this owner guide.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions, such as
slower speeds and increased stopping distance, should be taken when
driving a heavily loaded vehicle.
Your vehicle has the capability to haul more cargo and people than most
passenger cars. Depending upon the type and placement of the load,
hauling cargo and people may raise the center of gravity of the vehicle.
TRAILER TOWING
Trailer towing puts additional loads on your vehicle’s engine, transmission,
axle, brakes, tires, and suspension. For your safety and to maximize vehicle
performance, be sure to use the proper equipment while towing.

Follow these guidelines to ensure safe towing:
•Stay within your vehicle’s load limits.
•Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
•Use extra caution when driving while trailer towing. Refer toDriving
while you towin this chapter.
•Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the scheduled maintenance guide.
•Do not tow a trailer until your vehicle has been driven at least
500 miles (800 km). Additionally, during the first 500 miles (800 km)
that you tow a trailer, do not drive over 70 mph (112 km/h) and do
not make starts at full throttle.
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
Trailer towing (standard equipment):
Your vehicle is equipped with a integrated trailer hitch and a Class I
(4-pin) trailer electrical connector. The 4-pin connector supplies power
to tail lamps, stop lamps, and turn lamps. See the trailer towing chart for
the trailer towing weight recommendation.
Trailer towing (optionally equipped trailer tow package):
The optional trailer tow package includes heavy duty trailer tow wiring.
Both a Class I (4-pin) and IV (7-pin) trailer electrical connector are
provided. Under the instrument panel a electrical connector is provided
for a customer supplied aftermarket electronic brake controller. For
installing a customer supplied electronic brake controller, a electrical
jumper harness and trailer tow electrical instructions are included with
the optional trailer tow package.
The kit containing a electrical jumper and trailer tow electrical
instructions may be purchased from any authorized dealer (Part number
4L1Z-14A348-AA)
Note:Before towing a trailer, make sure the trailer brakes (if equipped)
and lamps are properly connected and functional. Electronic trailer
brakes (if equipped) refer to the instructions provided by the
aftermarket electronic brake controller manufacture for determining
trailer brake functionality.

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:
•Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, 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.
•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 the
Understanding the positions of the 6–speed automatic
transmissionsection in this chapter.

•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
If your vehicle is equipped with AdvanceTrac
with RSC, you may
experience AdvanceTrac
with RSC activations during typical cornering
maneuvers with a heavily loaded trailer; this is normal. Cornering at a
slower speed while towing will reduce the tendency of the AdvanceTrac

stability enhancement system to activate.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourScheduled Maintenance Guide
for more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•
The trailer tongue weight should be 10–15% of the loaded trailer weight.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 500 miles (800 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (112 km/h) with no full throttle starts.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
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.

To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
BRAKES
Your service brakes are self-adjusting. Refer to thescheduled
maintenance informationfor scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by an authorized dealer.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Anti-lock brake system (ABS)
On ABS-equipped vehicles, a noise from the hydraulic pump motor and
pulsation in the pedal may be observed during ABS braking events. Pedal
pulsation coupled with noise while braking under panic conditions or on
loose gravel, bumps, wet or snowy roads is normal and indicates proper
functioning of the vehicle’s anti-lock brake system. The ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by an authorized dealer.

The ABS operates by detecting the onset of wheel lockup during brake
applications and compensates for this tendency. The wheels are
prevented from locking even when the brakes are firmly applied.
Using ABS
•In an emergency or when maximum efficiency from the four-wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain steering
control of your vehicle and, providing there is sufficient space, will
enable you to avoid obstacles and bring the vehicle to a controlled
stop.
•The anti-lock system does not always reduce stopping distance.
Always leave enough room between your vehicle and the vehicle in
front of you to stop.
•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
ABS warning lamp
The ABS warning lamp in the
instrument cluster momentarily
illuminates when the ignition is
turned on. If the light does not
illuminate momentarily at start up,
remains on or continues to flash, the ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately.)

Parking brake with auto-release (if equipped)
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is released.
Always set the parking
brake fully and make sure
that the gearshift is securely
latched in P (Park).
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Your vehicle has an automatic parking brake release. To release the
parking brake:
1. Turn the ignition to the ON position.
2. Press the brake pedal.
3. Move the gearshift out of the P (Park) position (the parking brake will
release automatically when you shift into reverse). The brake pedal must
remain pressed while the gearshift is moved.
