PRINCIPLE OF OPERATION
WARNINGS
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. The AdvanceTrac Control system helps
you keep control of your vehicle when on
a slippery surface. The electronic stability
control portion of the system helps avoid
skids and lateral slides. The traction
control system helps avoid drive wheel
spin and loss of traction. See Using
Traction Control (page 151). Vehicle without AdvanceTrac
skidding off its intended route.

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.

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 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 WARNING
If the tire label shows
different tire pressures for the
front and rear tires and the vehicle
is equipped with a tire pressure
monitoring system, then the
settings for the system sensors
need to be updated. Always
perform the system reset
procedure after tire rotation. If the
system is not reset, it may not
provide a low tire pressure
warning when necessary. See Tire
Pressure Monitoring System
(page 253). 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.
251
Focus (CDH), enUSA, First Printing Wheels and Tires

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.
USING SNOW 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, transfer
case or 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 or snow chains.
If you choose to install snow tires on your
vehicle, they must be the same size,
construction, and load range as the original
tires listed on the tire inflation pressure
label (located on the edge of the driver
door or the B-Pillar) and they must be
installed on all four wheels. Mixing tires of
different size or construction on your
vehicle can adversely affect your vehicle
’s
handling and braking, and may lead to loss
of vehicle control.
If you use snow chains, we recommend
that steel wheels of the same size and
specifications are used. Snow chains may
damage aluminum wheels.
Follow these guidelines when using snow
chains:
• Avoid fully loading your vehicle.
• Use SAE Class S chains with 215/55R16
tires only. Do not use tire chains with
any other tire sizes.
• Snow chains must be mounted in pairs
on the front axle.
• Install snow chains securely, make sure
they do not touch any wiring, brake
lines or fuel lines.
• Do not exceed 30 mph (48 km/h) or
the maximum speed recommended by
the chain manufacturer, whichever is
less.
• Remove the cables when they are no
longer needed.
• Do not use snow chains on dry roads.

NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor®
Your vehicle is equipped with an Intelligent
Oil-Life Monitor that determines when you
should change the engine oil based on how
your vehicle is used. By using several
important factors in its calculations, the
monitor helps reduce the cost of owning
your vehicle and reduces environmental
waste at the same time. This means you do not have to remember
to change the oil on a mileage-based
schedule. Your vehicle lets you know when
an oil change is due by displaying ENGINE
OIL CHANGE DUE or OIL CHANGE
REQUIRED in the information display.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.
