PRINCIPLE OF OPERATION
Electronic Stability Program
WARNINGS
The system does not relieve you of
your responsibility to drive with due
care and attention. Failure to drive
with due care and attention could lead to
loss of vehicle control. Vehicle modifications involving
braking system, aftermarket roof
racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of the vehicle and may adversely affect
the performance of the AdvanceTrac
system. In addition, installing any stereo
loudspeakers may interfere with and
adversely affect the AdvanceTrac 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 AdvanceTrac sensors. Reducing the
effectiveness of the AdvanceTrac system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. 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
AdvanceTrac 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 AdvanceTrac
system activates, SLOW DOWN. Without Advance Trac

The system supports stability when your
vehicle starts to slide away from your
intended path. This is performed by braking
individual wheels and reducing engine
torque as needed.
The system also provides an enhanced
traction control function by reducing
engine torque if the wheels spin when you
accelerate. This improves your ability to
pull away on slippery roads or loose
surfaces, and improves comfort by limiting
wheel spin in hairpin bends.
Stability Control Warning Lamp
While driving, it flashes when the system
is operating. See Warning Lamps and
Indicators (page 76).

STEERING
Electric Power Steering
WARNING
The electric power steering system
has diagnostic checks that
continuously monitor the system. If
a fault is detected, a message displays in
the information display. Stop your vehicle
as soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked by an authorized dealer. Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components. •
Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.

WARNINGS
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.
Additionally the use of
non-recommended tires and
wheels could cause steering,
suspension, axle, transfer case or
power transfer unit failure. If you
have questions regarding tire
replacement, contact your
authorized dealer as soon as
possible. 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. WARNINGS
When inflating the tire for
mounting pressures up to 20 psi
(1.38 bar) greater than the
maximum pressure on the tire
sidewall, the following
precautions must be taken to
protect the person mounting the
tire:
1. Make sure that you have the
correct tire and wheel size.
2. Lubricate the tire bead and
wheel bead seat area again.
3. Stand at a minimum of 12 ft
(3.66 m) away from the wheel
and tire assembly.
4. Use both eye and ear
protection.
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.
Always inflate steel carcass tires
with a remote air fill with the
person inflating standing at a
minimum of 12 ft (3.66 m) away
from the wheel and tire assembly Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle

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’re
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 (as
indicated in the Scheduled
Maintenance chapter) will help
your tires wear more evenly,
providing better tire performance
and longer tire life.
Front-wheel drive vehicles (front
tires on the left side of the
diagram) Sometimes irregular tire wear can
be corrected by rotating the tires.

MAINTENANCE
Your vehicle is equipped with an oil minder
system that indicates when the engine oil
should be changed under normal operating
conditions.
This means you do not have to remember
to change the oil on a mileage-based
schedule; the vehicle lets you know when
an oil change is due by displaying ENGINE
OIL CHANGE DUE or OIL CHANGE
REQUIRED in the information display.
