HOW DOES ALL-WHEEL DRIVE
WORK
The all-wheel drive system is designed to
continuously monitor and adjust power
delivery to the front and rear wheels to
optimize both traction and handling.
There is further information on driving in
unique driving conditions. See Driving
Hints (page 280). ALL-WHEEL DRIVE
PRECAUTIONS WARNING:
Do not become
overconfident in the ability of all-wheel
drive vehicles. Although an all-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
ALL-WHEEL DRIVE
LIMITATIONS
The all-wheel drive system is not intended
for use with mismatched tires.
Different tire sizes between the front and
rear axles can cause system damage.

HOW DOES STABILITY
CONTROL WORK
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. 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 electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
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 electronic stability
control system 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
electronic stability control system
activates, SLOW DOWN. If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
•
The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced power.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
Electronic stability control enhances your
vehicle ’s ability to prevent skids or lateral
slides by applying brakes to one or more
of the wheels individually and, if necessary,
reducing power.
Curve Control
Curve control enhances your vehicle ’s
ability to follow the road when cornering
severely or avoiding objects in the roadway.
Curve control operates by reducing power
and, if necessary, applying brakes to one
or more of the wheels individually.
Traction Control
Traction control enhances your vehicle ’s
ability to maintain traction of the wheels
by detecting and controlling wheel spin.
See What Is Traction Control (page 199).

HOW DOES ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
WORK
Adaptive cruise control with stop and go
uses radar and camera sensors to maintain
a set gap between your vehicle and the
vehicle in front of you while following it to
a complete stop. Stop and go can also be
set to follow a vehicle directly in front of
you and adjust the set speed, while you are
at a complete stop.
ADAPTIVE CRUISE CONTROL
PRECAUTIONS
WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death. WARNING: Pay close attention to
changing road conditions such as
entering or leaving a highway, on roads
with intersections or roundabouts, roads
without visible lanes of travel, roads that
are winding, slippery, unpaved, or steep
slopes. WARNING:
The system is not a
crash warning or avoidance system. WARNING:
Do not use tire sizes
other than those recommended because
this can affect the normal operation of
the system. Failure to do so may result
in a loss of vehicle control, which could
result in serious injury. WARNING:
Do not use the system
in poor visibility, for example fog, heavy
rain, spray or snow.
When Following a Vehicle WARNING:
When following a
vehicle that is braking, your vehicle does
not always decelerate quickly enough to
avoid a crash without driver intervention.
Apply the brakes when necessary. Failure
to follow this instruction could result in
personal injury or death.
Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep slopes,
for example in mountainous areas.
ADAPTIVE CRUISE CONTROL

LOCATING THE TIRE LABEL
You will find a Tire Label
containing tire inflation pressure
by tire size and other important
information located on the B-Pillar
or the edge of the driver's door.
See Locating the Safety
Compliance Certification
Labels
(page 271).
DEPARTMENT OF
TRANSPORTATION UNIFORM
TIRE QUALITY GRADES Tire Quality Grades apply to new
pneumatic passenger car tires.
The Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:
Treadwear 200
Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the
United States Department of
Transportation has set. Tire Quality Grades apply to new
pneumatic passenger car tires.
They do not apply to deep tread,
winter-type snow tires,
space-saver or temporary use
spare tires, light truck or LT type
tires, tires with nominal rim
diameters of 10 to 12 inches or
limited production tires as defined
in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).
U.S. Department of
Transportation Tire quality
grades:
The U.S. Department of
Transportation requires us to give
you the following information
about tire grades exactly as the
government has written it.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test course.
For example, a tire graded 150
would wear 1½ times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of their
use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.

TIRE REPLACEMENT
REQUIREMENTS
Your vehicle is equipped with tires
designed to provide a safe ride
and handling capability. WARNING:
Only use
replacement tires and wheels
that are the same size, load
index, speed rating and type
(such as P-metric versus
LT-metric or all-season versus
all-terrain) as those originally
provided by Ford. The
recommended tire and wheel
size may be found on either the
Safety Compliance Certification
Label (affixed to either the door
hinge pillar, door-latch post, or
the door edge that meets the
door-latch post, next to the
driver's seating position), or the
Tire Label which is located on
the B-Pillar or edge of the
driver's door. If this information
is not found on these labels, then
you should contact your
authorized dealer as soon as
possible. 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.
WARNING:
To reduce the
risk of serious injury, when
mounting replacement tires and
wheels, you should not exceed
the maximum pressure indicated
on the sidewall of the tire to set
the beads without additional
precautions listed below. If the
beads do not seat at the
maximum pressure indicated,
re-lubricate and try again. WARNING: For a mounting
pressure more than
20 psi
(1.38 bar) greater than the
maximum pressure, a Ford
dealer or other tire service
professional should do the
mounting. WARNING:
Always inflate
