SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury to yourself or others? In
this guide, answers to such questions are contained in comments
highlighted by the warning triangle symbol. These comments should be
read and observed.
Warning symbols on your vehicle
When you see this symbol, it is
imperative that you consult the
relevant section of this guide before
touching or attempting adjustment
of any kind.
Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste, cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
BREAKING-IN YOUR VEHICLE
During the first 1,000 miles (1,600 km) of driving, maintain speeds below
70 mph (112 km/h) and vary speeds frequently. This is recommended to
give the moving parts a chance to break-in.
Do not tow a trailer or use your vehicle to snowplow until it has been
driven at least 500 miles (800 km). Refer toTrailer towingin theTires,
Wheels and Loadingchapter for more information on towing a trailer
andSnowplowingin theDrivingchapter.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter for more information on oil
usage.

Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the RUN position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
The FUEL icon and arrow indicates
which side of the vehicle the fuel
filler door is located.
Refer toFilling the tankin theMaintenance and Specifications
chapter for more information.
Battery voltage gauge (manual
transmission only):Indicates the
battery voltage when the ignition is
in the RUN position. If the pointer
moves and stays outside the normal
operating range, have the vehicle’s
electrical system checked as soon as
possible.
Transmission fluid temperature gauge (automatic transmission
only):If the gauge is in the:
Normal area(normal) - the
transmission fluid is within the
normal operating temperature
(between “H” and “C”).
Yellow area(warning) — the
transmission fluid is higher than
normal operating temperature. This
can be caused by special operation
conditions (i.e. snowplowing, towing
or off road use). Refer toSpecial
Operating Conditionsin the
scheduled maintenance
informationfor instructions. Operating the transmission for extended
periods of time with the gauge in the yellow area may cause internal
transmission damage.

GENERAL AUDIO INFORMATION
Radio frequencies
AM and FM frequencies are established by the Federal Communications
Commission (FCC) and the Canadian Radio and Telecommunications
Commission (CRTC). Those frequencies are:
AM - 530, 540–1700, 1710 kHz
FM- 87.7, 87.9–107.7, 107.9 MHz
Radio reception factors
There are three factors that can affect radio reception:
•Distance/strength: The further you travel from an FM station, the
weaker the signal and the weaker the reception.
•Terrain: Hills, mountains, tall buildings, power lines, electric fences,
traffic lights and thunderstorms can interfere with your reception.
•Station overload: When you pass a broadcast tower, a stronger signal
may overtake a weaker one and play while the weak station frequency
is displayed.
CD/CD player care
Do:
•Handle discs by their edges only.
Never touch the playing surface.
•Inspect discs before playing.
Clean only with an approved CD
cleaner and wipe from the center
out.
•Wipe discs from the center out.
Don’t:
•Expose discs to direct sunlight or heat sources for extended periods
of time.
•Insert more than one disc into each slot of the CD changer magazine.
•Clean using a circular motion.
CD units are designed to only play commercially manufactured,
round (4.75 in / 12 cm) audio compact discs. Due to technical

Satellite radio reception factors:To receive the satellite signal, your
vehicle has been equipped with a satellite radio antenna located on the
roof of your vehicle. The vehicle roof provides the best location for an
unobstructed, open view of the sky, a requirement of a satellite radio
system. Like AM/FM, there are several factors that can affect satellite
radio reception performance:
•Antenna Obstructions: For optimal reception performance, keep the
antenna clear of snow and ice build-up and keep luggage and other
material as far away from the antenna as possible.
•Terrain: Hills, mountains, tall buildings, bridges, tunnels, freeway
overpasses, parking garages, dense tree foliage and thunderstorms can
interfere with your reception.
•Station overload: When you pass a ground based broadcast repeating
tower, a stronger signal may overtake a weaker one and result in an
audio mute.
Unlike AM/FM audible static, you will hear an audio mute when there is
a satellite radio signal interference. Your radio display may display NO
SIGNAL to indicate the interference.
SIRIUS satellite radio service:SIRIUS Satellite Radio is a continental
U.S. based satellite radio service that broadcasts over 120 channels of
music, sports, news and entertainment coast-to-coast. A service fee is
required in order to receive SIRIUS service. Vehicles that are equipped

Note:SIRIUS reserves the unrestricted right to change, rearrange, add
or delete programming including canceling, moving or adding particular
channels, and its prices, at any time, with or without notice to you. Ford
Motor Company shall not be responsible for any such programming
changes.
Satellite Radio Electronic Serial Number (ESN):This12digit
Satellite Serial Number is needed to activate, modify or track your
satellite radio account. You will need this number when communicating
with SIRIUS. While in Satellite Radio mode, you can view this number on
the radio display by pressing AUX and Preset 1 control simultaneously.
