non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure.
Follow the Ford recommended tire
inflation pressure found on the Safety
Compliance Certification Label (on the
door hinge pillar, door latch post or the
door edge that meets the door latch
post, next to the driver seat), or Tire
Label on the B-Pillar or the edge of the
driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and
adversely affect the way your vehicle
handles.
WARNING: Do not use snow chains
on snow-free roads.
Note: Do not use snow chains on vehicles
with LT275/65R20 or LT 285/75R18 sized
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 cables. If you need
to use cables, we recommend that you use
steel wheels of the same size and
specification, as cables may chip
aluminum wheels.
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 chains.
• Install chains securely, verifying that
the chains do not touch any wiring,
brake lines or fuel lines.
• Only install snow chains on the rear
axle. •
For Dual Rear Wheel (DRW) vehicles,
only install snow chains on the outer
wheel of each pair.
• Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when you no
longer need them. Do not use tire
chains on dry roads.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
Vehicle Tire Pressure Monitoring
System WARNING:
The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury. Check each tire, including the
spare, if provided, 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.

WARNING: To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park
(P), set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel,
place an appropriate block or wheel
chock on the right rear wheel. WARNING:
Always use the jack
provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight,
including any vehicle cargo or
modifications. If you are unsure if the jack
capacity is adequate, contact the
authorized dealer. WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death. WARNING:
Never place anything
between the vehicle jack and your
vehicle. WARNING:
Never place anything
between the vehicle jack and the ground. WARNING:
Park your vehicle so
that you do not obstruct the flow of
traffic or place yourself in any danger and
set up a warning triangle. WARNING:
Do not work on your
vehicle when the jack is the only support
as your vehicle could slip off the jack.
Failure to follow this instruction could
result in personal injury or death. WARNING:
Do not get under a
vehicle that is only supported by a
vehicle jack. WARNING:
Do not attempt to
change a tire on the side of the vehicle
close to moving traffic. Pull far enough
off the road to avoid the danger of being
hit when operating the jack or changing
the wheel. WARNING:
Only use the spare
wheel carrier to stow the wheel provided
with your vehicle. Other wheel sizes
could cause the spare wheel carrier to
fail if it does not fit securely or is too
heavy.
Note: Do not use impact tools or power
tools operating at over 200 RPM on the
spare wheel carrier winch, which may cause
it to malfunction and prevent a secure fit.
Override the winch at least three times
(there is an audible click each time) to make
sure the wheel and tire fit securely.
Note: Passengers should not remain in the
vehicle when the vehicle is being jacked.
1. Park the vehicle on a level firm ground and activate the hazard flashers.
2. Apply the parking brake, place the transmission in park (P), switch the
engine off.
3. Block the wheel diagonally opposite the flat tire. For example, if the left
front tire is flat, block the right rear
wheel.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING: When you install a wheel, always remove any corrosion, dirt or foreign
materials present on the mounting surfaces of the wheel or the surface of the wheel
hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners
that attach the rotor to the hub so they do not interfere with the mounting surfaces of
the wheel. Installing wheels without correct metal-to-metal contact at the wheel
mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while
your vehicle is in motion, resulting in loss of vehicle control, personal injury or death. lb.ft (Nm)

recommended replacement fasteners.
On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torque
at 100 mi (160 km) after any wheel disturbance, such as tire rotation, changing a flat tire,
or wheel removal.
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts to the specified
torque at
100 mi (160 km), and again at 500 mi (800 km) of new vehicle operation and
after any wheel disturbance, such as tire rotation, changing a flat tire, or wheel removal.
It is important to follow the proper wheel mounting and lug nut torque procedures. Wheel pilot bore

SYNC™ APPLICATIONS AND
SERVICES
• 911 Assist: Can alert 911 in the event of
an emergency.
• SYNC AppLink: Allows you to connect
to and use certain applications (if your
phone is compatible).
These features may require activation.
Available AppLink enabled apps vary by
market.
911 Assist WARNING:
Unless the 911 Assist
setting is set on before a crash, the
system will not dial for help which could
delay response time, potentially
increasing the risk of serious injury or
death after a crash. WARNING:
Do not wait for 911
Assist to make an emergency call if you
can do it yourself. Dial emergency
services immediately to avoid delayed
response time which could increase the
risk of serious injury or death after a
crash. If you do not hear 911 Assist within
five seconds of the crash, the system or
phone may be damaged or
non-functional. WARNING:
Always place your
phone in a secure location in your vehicle
so it does not become a projectile or get
damaged in a crash. Failure to do so may
cause serious injury to someone or
damage the phone which could prevent
911 Assist from working properly.
Note: The SYNC 911 Assist feature must be
set on before the incident.
Note: The SYNC 911 Assist feature only
operates in the U.S., Canada or in a territory
in which 911 is the emergency number.
Note: Before setting this feature on, make
sure that you read the 911 Assist Privacy
Notice later in this section for important
information.
Note: If any user switches 911 Assist to on
or off, that setting applies for all paired
phones. If 911 Assist is switched off, either
a voice message plays or a display message
or an icon comes on when your vehicle is
started and after a previously paired phone
connects.
Note: Every phone operates differently.
While SYNC 911 Assist works with most
cellular phones, some may have trouble
using this feature.
