WARNING LIGHTS AND CHIMES
Low fuel
Illuminates as an early reminder of a
low fuel condition indicated on the
fuel gauge (refer toFuel Gaugein
this chapter for more information).
When refueling, after the light
comes on, the amount of fuel that is added will be less than the
advertised capacity since there is fuel still in the tank. The ignition must
be in the ON position for this lamp to illuminate. The lamp will also
illuminate for several seconds after the ignition is turned to the ON
position regardless of the fuel level to ensure your bulb is working.
Service engine soon
Your vehicle is equipped with a
computer that monitors the engine’s
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD
II). The OBD II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD II system also assists the
service technician in properly servicing your vehicle.
TheService Engine Soonindicator light illuminates when the ignition is
first turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine’s emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.

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:
•engine coolant temperature is
very high
•engine 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.

Speedometer
Indicates the current vehicle speed.
Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the“H”and“C”). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
carechapter.
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 carechapter.

Trip odometer
Registers the kilometers (miles) of
individual journeys. Press and
release the reset button until a“T”
appears in the display (this
represents the trip mode). Press
and hold the button for three 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 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 by arrows), 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“L”and“H”).
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 (IF EQUIPPED)
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.

Large metallic objects, electronic
devices on the key chain that can be
used to purchase gasoline or similar
items, or a second key on the same
key ring as thecoded keymay
cause vehicle starting issues. If
present, you need to keep these
objects from touching thecoded
keywhile starting the engine. These
objects and devices cannot damage
thecoded key,but can cause a
NO—START condition if they are
too close to the key during engine
start. If a problem occurs, turn
ignition OFF and restart the engine
with all other objects on the key
ring held away from the ignition key. Check to make sure thecoded key
is an approved Fordcoded key.
If your keys are lost or stolen you
will need to do the following:
•Use your spare key to start the
vehicle, or
•Have your vehicle towed to a
dealership or locksmith. The key
codes will need to be erased from
your vehicle and new key codes will need to be re-coded.
Replacing coded keys can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
The correctcoded keymust be used for your vehicle. The use of the
wrong type ofcoded keymay lead to a“NO-START”condition.
If an unprogrammed key is used in the ignition it will cause a
“NO START”condition.
