High beams
Illuminates when the high beam
headlamps are turned on.
SecuriLockYanti-theft system
This light indicates the anti-theft
alarm system is armed. Momentarily
illuminates when the ignition is
turned to ON/START. If the light
fails to illuminate, continues to flash
or remains on, have the system serviced. Refer toSecuriLockypassive
anti-theft systemin theControls and featureschapter.
Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the battery is not
charging properly, requiring
electrical system service.
Oil pressure/Engine coolant
This light will come on when the
key is in the ON position and the:
²engine coolant temperature is
very high
²engine oil pressure is low
The light serves as a notice that a system needs your attention and to
check the engine coolant temperature gauge and the engine oil pressure
gauge.
Refer toEngine coolant temperature gaugeandEngine oil pressure
gaugein this chapter for more information.

Never remove the coolant reservoir cap while the engine is
running or hot.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the oil
pressure/engine coolant andCheck Engine/Service Engine Soon
indicators illuminate, refer toWhat you should know about fail-safe
coolingin theMaintenance and care chapter.
Odometer
Registers the total kilometers
(miles) of the vehicle.
Trip odometer
Registers the kilometers (miles) of
individual journeys. Press and
release the reset button until a ªTº
appears in the display (this
represents the trip mode). Press
and hold the button for 2.5 seconds to reset.
Tachometer
Indicates the engine speed in
revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale may damage the engine.

Battery voltage gauge
This gauge shows the battery
voltage when the ignition is in the
ON position. If the pointer moves
and stays outside the normal
operating range (as indicated), have
the vehicle's electrical system
checked as soon as possible.
Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the ªLº and ªHº).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.
Add oil if needed (refer toEngine oilin theMaintenance and care
chapter). If the oil level is correct, have your vehicle checked at your
dealership or by a qualified technician.
TRIP COMPUTER
The trip computer tells you about the condition of your vehicle through
a constant monitor of vehicle systems. You may select display features on
the trip computer for a display of status.
The appearance of your vehicle's trip computer may differ depending on
your vehicle's option package, but the functions are the same.
The trip computer only works when the ignition is in the ON position.

Power distribution box
The power distribution box is
located in the engine compartment.
The power distribution box contains
high-current fuses that protect your
vehicle's main electrical systems
from overloads.
Always disconnect the battery before servicing high current
fuses.
Always replace the cover to the Power Distribution Box before
reconnecting the battery or refilling fluid reservoirs.

Checking the engine oil
Refer to the Scheduled Maintenance Guide for the appropriate intervals
for checking the engine oil .
1. Make sure the vehicle is on level ground.

2. Turn the engine off and wait a few minutes for the oil to drain into the
oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
4. Open the hood. Protect yourself from engine heat.
5. Locate and carefully remove the
engine oil level indicator (dipstick).
6. Wipe the indicator clean. Insert the indicator fully, then remove it
again.
²If the oil level isbetween the MIN and MAX marks,the oil level is
acceptable.DO NOT ADD OIL.
²If the oil level is below the MIN
mark, add enough oil to raise the
level within the MIN-MAX range.
²Oil levels above the MAX mark may cause engine damage. Some oil
must be removed from the engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.

Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the MIN and MAX ranges, add only
certified engine oil of the recommended viscosity. Remove the engine oil
filler cap and use a funnel to pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
MAX mark on the dipstick.
Engine oil and filter recommendations
Look for this certification mark.
Ford oil specification is WSS-M2C153-G.
Use SAE 5W-30 motor oil certified for gasoline engines by the American
Petroleum Institute.
Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the Scheduled Maintenance Guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, startup
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

show how temperature impacts fuel economy. In general, lower
temperatures give lower fuel economy.
Driving style Ð good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
²Smooth, moderate operation can yield up to 10% savings in fuel.
²Steady speeds without stopping will usually give the best fuel
economy.
²Idling for long periods of time (greater than one minute) may waste
fuel.
²Anticipate stopping; slowing down may eliminate the need to stop.
²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.
²Drive at reasonable speeds (traveling at 105 km /h [65 mph] uses 15%
more fuel than traveling at 88 km/h [55 mph]).
²Revving the engine before turning it off may reduce fuel economy.
²Use of the air conditioner or defroster may reduce fuel economy.
²Use of speed control (if equipped) may improve fuel economy. Speed
control can help maintain a constant speed and reduce speed changes.
You may want to turn off the speed control in hilly terrain as
unnecessary shifting between third and fourth gears may occur and
could result in reduced fuel economy.
²Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
²Resting your foot on the brake pedal while driving may reduce fuel
economy.
²Combine errands and minimize stop-and-go driving.
Maintenance
²Keep tires properly inflated and use only recommended size.
²Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
²Use recommended engine oil. Refer toLubricant Specifications.
