WARNING: Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system: If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness: If this light fails
to illuminate when the ignition is
turned to on, continues to flash or
remains on, have the system
serviced immediately by your
authorized dealer. A chime will sound if there is a malfunction in the
indicator light.

your safety belt. A Belt-Minder 
chime will also sound to remind you
to fasten your safety belt. Refer to
the Seating and Safety Restraints
chapter to activate/deactivate the Belt-Minder  chime feature.
Charging system: Illuminates when
the battery is not charging properly.
If it stays on while the engine is
running, there may be a malfunction
with the charging system. Contact your authorized dealer as soon as
possible. This indicates a problem with the electrical system or a related
component.
Engine oil pressure (RTT and
static warning light): Displays
when the oil pressure falls below the

EMISSION CONTROL SYSTEM
WARNING: 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.
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 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 which 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 other than Ford, Motorcraft  or Ford-authorized parts are used 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.Maintenance and Specifications

Note: During extended periods of vehicle storage (30 days or more),
fuel may deteriorate due to oxidation. Add a quality gas stabilizer
product to the vehicle fuel system whenever actual or expected storage
periods exceed 30 days. Follow the instructions on the additive label.
The vehicle should then be operated at idle speed to circulate the
additive throughout the fuel system.
Cooling system
• Protect against freezing temperatures.
• When removing vehicle from storage, check coolant fluid level.
Confirm there are no cooling system leaks, and fluid is at the
recommended level.
Battery
• Check and recharge as necessary. Keep connections clean.
• If storing your vehicle for more than 30 days without recharging the
battery, it may be advisable to disconnect the battery cables to ensure
battery charge is maintained for quick starting.
