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 (manual
transmission only):Indicates 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:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (between“L”and
“H”). If the needle falls below the
normal range, stop the vehicle, turn
off the engine and check the engine
oil level. Add oil if needed. If the oil
level is correct, have your vehicle
checked at your dealership or by a
qualified technician.
Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
Refer toFilling the tankin the
Maintenance and Specifications
chapter for more information.

HOMELINKWIRELESS CONTROL SYSTEM WITH TRAVELNOTE
(IF EQUIPPED)
The HomeLinkWireless Control System, located on the driver’s visor,
provides a convenient way to replace up to three hand-held transmitters
with a single built-in device. This feature will learn the radio frequency
codes of most current transmitters to operate garage doors, entry gate
operators, security systems, entry door locks, and home or office lighting.
When programming your HomeLinkWireless Control System to
a garage door or gate, be sure that people and objects are out of
the way to prevent potential harm or damage.
Do not use the HomeLinkWireless Control System with any garage
door opener that lacks safety stop and reverse features as required by
U.S. federal safety standards (this includes any garage door opener
model manufactured before April 1, 1982). A garage door which cannot
detect an object, signaling the door to stop and reverse, does not meet
current U.S. federal safety standards. For more information, contact
HomeLinkat:www.homelink.comor1–800–355–3515.
Retain the original transmitter for use in other vehicles as well as for
future programming procedures (i.e. new HomeLinkequipped vehicle
purchase). It is also suggested that upon the sale of the vehicle, the
programmed Homelinkbuttons be erased for security purposes, refer to
Programmingin this section.
Programming
Do not program HomeLinkwith the vehicle parked in the garage.
Note:Your vehicle may require the ignition switch to be turned to the
ACC position for programming and/or operation of the HomeLink.Itis
also recommended that a new battery be placed in the hand-held
transmitter of the device being programmed to HomeLinkfor quicker
training and accurate transmission of the radio-frequency signal.
1. Press and hold the two outside
buttons releasing only when the red
light begins to flash after 20
seconds.Do notrepeat step one to
program additional hand-held
transmitters to the remaining two
HomeLinkbuttons. This will erase
previously programmed hand-held
transmitter signals into HomeLink.

2. Press the E/M and MODE
controls simultaneously. The display
will illuminate the“AV G”indicator.
While the indicator is lit, release
both controls to reset the average
fuel economy.
Fuel range.This function estimates approximately how far you can
drive with the fuel remaining in your tank under normal driving
conditions. Remember to turn the ignition OFF when refueling to allow
this feature to correctly detect the added fuel.
The DTE function will flash for 5 seconds when you have approximately:
•80 km (50 miles) left before you run out of fuel
•40 km (25 miles)
•16 km (10 miles)
DTE is calculated using a running average fuel economy, which is based
on your recent driving history of 800 km (500 miles). This value is not
the same as the average fuel economy display. The running average fuel
economy is reinitialized to a factory default value if the battery is
disconnected.
Outside air temperature
The temperature can be displayed in
Centigrade or Fahrenheit by
pressing the E/M control.
If the outside temperature falls
below 3°C (38°F), the display will
alternate from“ICE”to the outside
temperature at a two second rate
for one minute.
Off.In this mode the display is off.

The UNLOCKfeature will work again after:
•a door has become ajar,
•the ignition is turned to the ON position,
•unlocking the vehicle using the keyless entry keypad,
•or using the UNLOCK
control on your remote entry transmitter (if
equipped).
This feature is initially deactivated, but may be activated by taking your
vehicle to an authorized Ford dealer.
Sounding a panic alarm
Press
to activate the alarm. Press again or turn the ignition to ACC
or ON to deactivate.
Note:The panic alarm will only operate when the ignition is in the OFF
position.
Replacing the battery
The remote entry transmitter uses one coin type three-volt lithium
battery CR2032 or equivalent. The typical operating range for your
remote entry transmitter is approximately 10 meters (33 feet). A
decrease in the operating range could be caused by:
•weather conditions,
•nearby radio towers,
•structures around the vehicle and
•other vehicles parked next to the vehicle.
To replace the battery:
1. Twist a thin coin between the two
halves of the remote entry
transmitter near the key ring. DO
NOT TAKE THE RUBBER COVER
AND CIRCUIT BOARD OFF THE
FRONT HOUSING OF THE
REMOTE ENTRY TRANSMITTER.

2. Do not wipe off any grease on the
battery terminals on the back
surface of the circuit board.
3. Remove the old battery.
4. Insert the new battery. Refer to the diagram inside the remote entry
transmitter for the correct orientation of the battery. Press the battery
down to ensure that the battery is fully seated in the battery housing
cavity.
5. Snap the two halves back together.
Note:Replacement of the battery willnotcause the remote transmitter
to become deprogrammed from your vehicle. The remote transmitter
should operate normally after battery replacement.
Replacing lost remote entry transmitters
If you would like to have your remote entry transmitter reprogrammed
because you lost one, or would like to buy additional remote entry
transmitters, you can either reprogram them yourself, or takeall
remote entry transmittersto your authorized dealer for
reprogramming.
How to reprogram your remote entry transmitters
You must haveall remote keyless entry keypads and remote entry
transmitters(maximum of four) available before beginning this
procedure.
