Highway Hazards
No matter how carefully you drive,
there is 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 are
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 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.
Tire Rotation
Note:
If your tires show uneven
wear, ask an authorized dealer to
check for and correct any wheel
misalignment, tire imbalance or
mechanical problem involved
before tire rotation.
Note: Your vehicle may be
equipped with a dissimilar spare
wheel and tire assembly. A
dissimilar spare wheel and tire
assembly is defined as a spare
wheel and tire assembly that is
different in brand, size or
appearance from the road tires and
wheels. If you have a dissimilar
spare wheel and tire assembly, it is
intended for temporary use only
and should not be used in a tire
rotation.
Note: After having your tires
rotated, inflation pressure must be
checked and adjusted to the
vehicle requirements.

Rotating your tires at the
recommended interval will help
your tires wear more evenly,
providing better tire performance
and longer tire life. Sometimes
irregular tire wear can be
corrected by rotating the tires. See
Scheduled Maintenance (page
452). USING SUMMER TIRES
Summer tires provide superior
performance on wet and dry roads.
Summer tires do not have the Mud and
Snow (M+S or M/S) tire traction rating on
the tire side wall. Since summer tires do
not have the same traction performance
as All-season or Snow tires, we do not
recommend using summer tires when
temperatures drop to approximately 45°F
(7°C)
or below (depending on tire wear
and environmental conditions) or in snow
and ice conditions. Like any tire, summer
tire performance is affected by tire wear
and environmental conditions. If you must
drive in those conditions, we recommend
using Mud and Snow (M+S, M/S),
All-season or Snow tires. Always store your summer tires indoors at
temperatures above
19°F (-7°C). The
rubber compounds used in these tires lose
flexibility and may develop surface cracks
in the tread area at temperatures below
19°F (-7°C)
. If the tires have been
subjected to 19°F (-7°C) or less, warm
them in a heated space to at least 41°F
(5°C) for at least 24 hours before installing
them on a vehicle, or moving the vehicle
with the tires installed, or checking tire
inflation. Do not place tires near heaters
or heating devices used to warm the room
where the tires are stored. Do not apply
heat or blow heated air directly on the tires.
Always inspect the tires after storage
periods and before use.
USING SNOW CHAINS WARNING
Snow tires must be the same size,
load index and 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 control,
vehicle rollover, personal injury and death.
Additionally, the use of 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. 286

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.
If the tires on your vehicle have all season
treads, they will 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, it is recommended that
steel wheels (of the same size and
specifications) be used, as cables may chip
aluminum wheels.
Follow these guidelines when using snow
tires and chains:
• If possible, avoid fully loading your
vehicle.
• Use only SAE Class S snow chains,
snow cables or equivalent on the front
axle for P235/55R18 equipped vehicles.
The use of snow chains, snow cables
or other traction assist devices that are
larger than SAE Class S may cause
damage to your vehicle ’s wheel house,
suspension and/or body.
• Do not install tire chains, cables, or
optional traction devices on the rear
tires. This could cause damage to the
vehicle ’s wheel house or body.
• Install cable chains securely, verifying
that the cables do not touch any wiring,
brake lines or fuel lines.
• Do not exceed 30 mph (48 km/h) with
tire cables on your vehicle.
• 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.
• Remove the tire cables when they are
no longer needed. Do not use tire
cables on dry roads. 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. Note:
You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it may not
function. 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

How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about 2
–4 psi (14– 28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as
being significantly lower than the
recommended inflation pressure and
activate the system warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check
the air pressure in the road tires. If 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.
CHANGING A ROAD WHEEL WARNING
If the tire pressure monitor sensor
becomes damaged it may not
function.
Note:
The use of tire sealant may damage
your tire pressure monitoring system and
should only be used in roadside
emergencies.
Note: The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle. If you get a flat tire while driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer in order to prevent damage to the
tire pressure monitoring system sensors.
See
Tire Pressure Monitoring System
(page 287). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the tire
pressure monitoring system sensor for
damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING
Failure to follow these guidelines
could result in an increased risk of
loss of vehicle control, injury or death.
If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires

dissimilar spare wheel and tire assembly
and seek service as soon as possible.
Tire Change Procedure WARNINGS
When one of the front wheels is off
the ground, the transmission alone
will not prevent the vehicle from
moving or slipping off the jack, even if the
transmission is in park (P). 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. Do not work on your vehicle when
the jack is the only support. If the
vehicle slips off the jack, you or
someone else could be seriously injured.

2. Insert the straight end of the jack
retention bracket through the eyelet of
the angled bracket and swing the
retention bracket over the jack. With
the jack in place, place the end of the
retention bracket over the threaded
stud in the trunk floor and secure it with
the plastic wing nut.
3. Screw the extension bolt onto the threaded stud of the jack retention
bracket.
4. Place the flat tire in the spare tire well with the wheel facing up.
5. Safely secure the wheel by screwing the large wing nut onto the extension
bolt.
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. Ib-ft (Nm)
