TIRE PRESSURE MONITORING SYSTEM (TPMS)
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

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.
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 cables.
Note:The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when using
snow tires and chains.
Follow these guidelines when using snow tires and chains:
•If possible, avoid fully loading your vehicle.
•Use only SAE Class S cables or equivalent.
•Use SAE Class S cables only on the front axle on vehicles equipped
with P245/60R18 tires.
•Do not use tire cables or optional traction devices with P245/50R20 or
P265/40R22 tires.
•Install cables securely, verifying that the cables do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the cables rub or bang against your
vehicle, stop and retighten the cables. If this does not work, remove
the cables to prevent damage to your vehicle.
•Do not exceed 30 mph (48 km/h) with tire cables on your vehicle.
•Remove the tire cables when they are no longer needed. Do not use
tire cables on dry roads.
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

•Roll Stability Control™ (RSC), which functions to help avoid a
vehicle roll-over.
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 and
stability control off light will illuminate steadily. Verify that the
AdvanceTracwith RSCsystem was not manually disabled through
the message center. If the stability control light and stability control off
light still illuminate 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

The BLISand/or CTA alert will automatically dim when the headlamp
switch is in PARK, ON, or AUTO ON and night time darkness has been
detected by the sun sensor.
ALL-WHEEL DRIVE (IF EQUIPPED)
Your vehicle may be equipped with a full-time all-wheel drive (AWD)
system. The AWD system is an active system, meaning it not only
responds to wheel slip between the front and rear axles but also has the
ability to anticipate wheel slip and transfer torque to the rear wheels
before slip occurs. The AWD system is active all the time and requires no
input from the operator.
All components of the AWD system are sealed for life and require no
maintenance.
Note:When an AWD system fault is present, the warningCHECK AWD
will display in the message center. The AWD system is not functioning
correctly and defaulted to front-wheel drive. When this warning is
displayed, have your vehicle serviced at an authorized dealer
If your vehicle is equipped with AWD, a spare tire of a different size
other than the tire provided should never be used. If the spare tire is
installed, the AWD system may disable automatically and enter
front-wheel drive only mode to protect driveline components. This
condition may be indicated by anAWD OFFmessage in the message
center (seeMessage centersection in theInstrument Clusterchapter
for more information). If there is anAWD OFFmessage in the message
center from using the spare tire, this indicator should turn off after
reinstalling the repaired or replaced normal road tire and driving a short
distance. 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 AWD system to stop functioning and default
to front-wheel drive or damage the AWD system.
Note:TheAWD OFFmessage may also be displayed in the message
center if the AWD 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 AWD function as soon as possible, stop the vehicle in a safe
location and allow it to idle. TheAWD OFFmessage will turn off when
the system cools and normal AWD function returns.

If you are stowing a flat 22 inch tire and wheel assembly,
temporarily remove the load floor, plastic stowage bins (if equipped), and
the foam load floor supports to make space for the 22 inch tire and
wheel assembly. Place the 22 inch tire & wheel assembly in the spare tire
well with the valve stem facing down. Rotate the tire until the jack
assembly is able to protrude through a wheel opening. Replace the
plastic stowage bins (if equipped) and foam load floor supports around
the 22 inch tire and wheel assembly.
If you are stowing a flat tire,place the tire in the spare tire well with
the valve stem facing down. Rotate the tire until the jack assembly is
able to protrude through a wheel opening.
If you are stowing the spare tire,place the spare in the spare tire
well in its original position.
4. Secure the wheel by replacing the washer and the wing nut and
turning the wing nut clockwise.
WHEEL LUG NUT TORQUE SPECIFICATIONS

Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle may reduce fuel economy at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example; bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Close windows for high speed driving.
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.
