The fuel gauge indicator may vary
slightly when the vehicle is in
motion. The most accurate reading
is obtained with the vehicle on
level ground.
With ignition switch OFF, the fuel
gage indicator may drift from the
ignition switch ON position.
Refer theIgnitioninformation in
theControls and featureschapter
for more information on the
positions of the ignition.
Charging system gauge
If the pointer moves and stays
outside of the normal range, have
the vehicle's electrical system
checked as soon as safely possible.
Engine oil pressure gauge
Indicates the engine oil pressure in
the system. Sufficient pressure
exists as long as the needle is in
the normal range. If the gauge
constantly indicates low pressure
at normal engine speed, refer to
Checking and adding engine oil
in theMaintenance and care
chapter.
If the gauge indicates a low
pressure and the engine oil level is
correct, switch off the engine
immediately and have the vehicle

How fail-safe cooling works
If the engine overheats, the engine
will automatically switch from
eight to alternating four cylinder
operation. Each disabled cylinder
acts as an air pump and cools the
engine.
When this occurs, the engine
coolant temperature gauge will
move into the red area and the
light illuminates.
The service engine soon light will
illuminate, indicating that vehicle
service is required.
The vehicle will still operate, but
will have limited engine power and
no air conditioning capability.
Continued operation will increase
engine temperature and cause the
engine to completely shut down.
The vehicle will coast to a stop.
As the engine temperature cools,
the engine may be re-started. Take
your vehicle to a service facility as
soon as possible to minimize
engine damage.
CHECKING AND ADDING
POWER STEERING FLUID
Check the power steering fluid
level at least twice a year.
1. Start the engine.

²The help reduce early nozzle
shut offs and fuel spillage, park
your vehicle so that the fuel
filler door is level.
²Avoid excessively fast fuel
dispensing rates (over 38 L [10
gallons] per minute).
²If you spill any fuel on the body
of your vehicle, clean it off
immediately. The fuel may dull
or soften the paint if it is not
washed off promptly.

the tabs on the cap with the
notches on the filler pipe. Turn it
clockwise until it stops.
4. Push the fuel door closed.
If the check engine warning light
illuminates and remains illuminated
while the engine is started, the
fuel cap may not be properly
seated. Turn off the engine,
remove the fuel cap and replace it.
being sure to align the cap
properly.
If the fuel cap is lost, replace it
with an authorized Motorcraft or
equivalent part.
Calculating fuel economy
To accurately calculate your
vehicle's fuel economy:
1. Fill the tank completely and
record the initial odometer
reading.
2. Each time you fill the tank,
record the amount of fuel added
(in liters or gallons).
