SITTING IN THE CORRECT
POSITION
WARNING: Sitting improperly, out
of position or with the seatback reclined
too far can take weight off the seat
cushion and affect the decision of the
passenger sensing system, resulting in
serious injury or death in the event of a
crash. Always sit upright against your
seat back, with your feet on the floor. WARNING: Do not recline the seat
backrest too far as this can cause the
occupant to slide under the seatbelt,
resulting in personal injury in the event
of a crash. WARNING:
Do not place objects
higher than the top of the seat backrest.
Failure to follow this instruction could
result in personal injury or death in the
event of a sudden stop or crash. When you use them properly, the seat,
head restraint, seatbelt and airbags will
provide optimum protection in the event
of a crash. We recommend that you follow these
guidelines:
•
Sit in an upright position with the base
of your spine as far back as possible.
• Do not recline the seat backrest so that
your torso is more than 30 degrees
from the upright position.
• Adjust the head restraint so that the
top of it is level with the top of your
head and as far forward as possible.
Make sure that you remain
comfortable.
• Keep sufficient distance between
yourself and the steering wheel. We
recommend a minimum of
10 in
(25 cm) between your breastbone and
the airbag cover.
• Hold the steering wheel with your arms
slightly bent.
• Bend your legs slightly so that you can
press the pedals fully.
• Position the shoulder strap of the
seatbelt over the center of your
shoulder and position the lap strap
tightly across your hips.
Make sure that your driving position is
comfortable and that you can maintain full
control of your vehicle.
HEAD RESTRAINTS WARNING:
Fully adjust the head
restraint before you operate your vehicle.
This will help minimize the risk of neck
injury in the event of a crash. Do not
adjust the head restraint when your
vehicle is moving.

WHAT IS THE GARAGE DOOR
OPENER
HomeLink Wireless Control
System
The universal garage door opener replaces
the common hand-held garage door
opener with a three-button transmitter
integrated into the driver
’s sun visor.
HOW DOES THE GARAGE
DOOR OPENER WORK
The system includes two primary features,
a garage door opener and a platform for
remote activation of devices within the
home. You can program garage doors as
well as entry gate operators, security
systems, entry door locks and home or
office lighting.
Additional system information can be
found online at www.homelink.com or by
calling the toll-free help line at
1-800-355-3515.
Note: You can program a maximum of
three devices. To change or replace any of
the three devices after it has been initially
programmed, you must first erase the
current settings. See Clearing the Garage
Door Opener (page 143). GARAGE DOOR OPENER
PRECAUTIONS WARNING:
Do not use the system
with any garage door opener that does
not have the safety stop and reverse
feature as required by U.S. Federal
Safety Standards (this includes any
garage door opener manufactured
before April 1, 1982). A garage door
opener which cannot detect an object,
signaling the door to stop and reverse,
does not meet current federal safety
standards. Using a garage door opener
without these features increases the risk
of serious injury or death.
Note: Make sure that the garage door and
security device are free from obstruction
when you are programming. Do not program
the system with your vehicle in the garage.
Note: Make sure you keep the original
remote control transmitter for use in other
vehicles as well as for future system
programming.
Note: We recommend that upon the sale
or lease termination of your vehicle, you
erase the programmed function buttons for
security reasons. See Clearing the Garage
Door Opener
(page 143).
GARAGE DOOR OPENER
LIMITATIONS
Canadian radio-frequency laws require
transmitter signals to time-out (or quit)
after several seconds – which may not be
long enough for HomeLink to pick up the
signal.
U.S. gate operators time-out in the same
manner.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors can result in
reduced engine power and the illumination
of the service engine soon light.
Tampering With a Noise Control
System
Federal laws prohibit the following acts:
• Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design. The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
•
Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• Fuel system leaks, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, see your authorized
dealer as soon as possible.

CATALYTIC CONVERTER
WARNING: Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 234).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving. •
Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle ’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 296).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at
which you press the brake pedal. It
provides maximum braking efficiency as
long as you press the pedal. Emergency
brake assist can reduce stopping distances
in critical situations. Note:
Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
could flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily
illuminates when you switch the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the anti-lock braking system may
be disabled. Have the system checked by
an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still
effective.
See
Warning Lamps and Indicators
(page 94).
Note: Indicators vary depending on region. This lamp also illuminates
momentarily when you switch
the ignition on to confirm the
lamp is functional. If it does not
illuminate when you switch the
ignition on, or begins to flash at
any time, have the system checked by an
authorized dealer. If the brake warning
lamp illuminates with the parking brake
released, have the system checked
immediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
