Service Engine Soon
If the service engine soon
indicator light stays illuminated
after you start the engine, it
indicates that the On Board Diagnostics
system (OBD) has detected a malfunction
of the vehicle emissions control system.
Refer to On Board Diagnostics (OBD) in
the Fuel and Refueling chapter for more
information about having your vehicle
serviced. See Emission Control System
(page 156).
If the light is blinking, engine misfire is
occurring which could damage your
catalytic converter. Drive in a moderate
fashion (avoid heavy acceleration and
deceleration) and have your vehicle
serviced immediately. WARNING
Under engine misfire conditions,
excessive exhaust temperatures
could damage the catalytic
converter, the fuel system, interior floor
coverings or other vehicle components,
possibly causing a fire. Have your vehicle
checked as soon as possible. The service engine soon indicator light
illuminates when you first switch on the
ignition before engine start to check the
bulb and to indicate whether the vehicle
is ready for Inspection/Maintenance (I/M)
testing.
Normally, the service engine soon light
stays on until you crank the engine, then
turns itself off if no malfunctions are
present. However, if after 15 seconds the
service engine soon light blinks eight times,
it means that the vehicle is not ready for
I/M testing. See
Emission Control
System (page 156). Stability Control System Displays when the
AdvanceTrac®/Traction control
is active. If the light remains on,
have the system serviced immediately.
See
Using Stability Control (page 178).
Stability Control System Off Illuminates when you disable
AdvanceTrac®/Traction. See
Using Stability Control
(page
178).
Transmission Tow/Haul
(If Equipped) Illuminates when you activate
the tow/haul feature. If the light
flashes steadily, have the system
serviced immediately. Damage to the
transmission could occur. See
Automatic
Transmission (page 159).
4X2 Illuminates momentarily when
you engage two-wheel drive
high. If the light fails to display
or remains on when the ignition is on, have
the system serviced immediately by an
authorized dealer.
4X4 Auto Illuminates when you engage the
four-wheel drive system. If the
light fails to display or remains
on when the ignition is on, have the system
serviced immediately by an authorized
dealer.

Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of your
vehicle
’s fuel economy under current
driving conditions. Keeping records during
summer and winter will show how
temperature impacts fuel economy.
Conditions
• Heavily loading your vehicle reduces
fuel economy.
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks may reduce fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.
EMISSION CONTROL SYSTEM WARNINGS
Do not park, idle, or drive your vehicle
in dry grass or other dry ground cover.
The emission system heats up the
engine compartment and exhaust system,
which can start a fire. 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 dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes. Your vehicle is equipped with various
emission control components and a
catalytic converter that will enable your
vehicle to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
•
Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your
vehicle is moving, especially at high
speeds.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
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
