Average Fuel Economy (AVG ECO)
Shows the average fuel economy since the last reset.
Average fuel economy is a running average of the
amount of fuel used and the distance the vehicle has
traveled.
When the fuel economy is reset, the display will momen-
tarily blank. Then, the history information will be erased,
and the averaging will continue from where it was before
the reset. The reset value is based on a minimal amount
of fuel used and the distance traveled from the previous
drive cycle. The display may take several miles for this
value to change dependent upon driving habits.
Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance is
determined by weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. This is not resettableNOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles estimated
driving distance, the DTE display will change to an
alternating test display of “LO” and “FUEL”. This dis-
play will continue until the vehicle runs out of fuel.
Adding a significant amount of fuel to the vehicle will
turn off the “LO FUEL” text and a new DTE value will be
displayed, based on the current values in the DTE
calculation and the current fuel tank level.
NOTE:It is possible for DTE to display “LO FUEL”
before the low fuel warning light turns on in the instru-
ment cluster. This could occur because low fuel warning
is set to a specified fuel tank volume and DTE is an
estimated distance calculation based on fuel economy
and remaining fuel tank volume.

OVERHEAD CONSOLE WITH ELECTRONIC
VEHICLE INFORMATION CENTER (EVIC) —
DIESEL ONLY
The overhead console contains dome/reading lights, and

GARAGE DOOR OPENER — IF EQUIPPED
The HomeLinkUniversal Transceiver replaces up to
three remote controls (hand held transmitters) that oper-
ate devices such as garage door openers, motorized
gates, or home lighting. It triggers these devices at the
push of a button. The Universal Transceiver operates off
your vehicle’s battery and charging system; no batteries
are needed.
For additional information on HomeLink, call 1–800–
355–3515, or on the internet at www.homelink.com.

Programming HomeLink
NOTE:When programming a garage door opener, it is
advised to park outside the garage. It is also recom-
mended that a new battery be placed in the hand-held
transmitter of the device being programmed to
HomeLink for quicker training and accurate transmis-
sion of the radio-frequency signal.
1. Press and hold the two outer HomeLink buttons, and
release only when the indicator light begins to flash (after
20 seconds).Do nothold the buttons for longer than 30
seconds anddo notrepeat step one to program a second
and/or third hand-held transmitter to the remaining two
HomeLink buttons.2. Position the end of your hand-held transmitter 1-3
inches (3-8 cm) away from the HomeLink buttons while
keeping the indicator light in view.

3. Simultaneously press and hold both the HomeLink
button that you want to train and the hand-held trans-
mitter buttons.Do not release the buttons until step 4
has been completed.
NOTE:Some gate operators and garage door openers
may require you to replace this Programming Step 3 with
procedures noted in theGate Operator/Canadian Pro-
grammingsection.
4. The HomeLink indicator light will flash slowly and
then rapidly after HomeLink successfully receives the
frequency signal from the hand-held transmitter. Release
both buttons after the indicator light changes from the
slow to the rapid flash.
5. Press and hold the just trained HomeLink button and
observe the indicator light. If the indicator lightstays on
constantly, programming is completeand your device
should activate when the HomeLink button is pressed
and released.NOTE:To program the remaining two HomeLink but-
tons, begin withProgrammingstep two. Do not repeat
step one.
If the indicator light blinksrapidly for two seconds and
then turns to a constant light, continue withProgram-
mingsteps 6-8to complete the programming of a rolling
code equipped device (most commonly a garage door
opener).
6. At the garage door opener receiver (motor-head unit)
in the garage, locate thelearnorsmartbutton. This
can usually be found where the hanging antenna wire is
attached to the motor-head unit.
7. Firmly press and release thelearnorsmartbutton.
(The name and color of the button may vary by manu-
facturer.)
NOTE:There are 30 seconds in which to initiate step
eight.

8. Return to the vehicle and firmlypress, hold for two
seconds and releasethe programmed HomeLink button.
Repeat thepress/hold/releasesequence a second time,
and, depending on the brand of the garage door opener
(or other rolling code equipped device), repeat this
sequence a third time to complete the programming.
HomeLink should now activate your rolling code
equipped device.
NOTE:To program the remaining two HomeLink but-
tons, begin withProgrammingstep two. Do not repeat
step one. For questions or comments, please contact
HomeLink atwww.homelink.com or 1-800-355-3515.
Canadian Programming/Gate Programming
Canadian radio-frequency laws require transmitter sig-
nals totime-out(or quit) after several seconds of
transmission which may not be long enough for
HomeLink to pick up the signal during programming.Similar to this Canadian law, some U.S. gate operators are
designed totime-outin the same manner.
If you live in Canada or you are having difficulties
programming a gate operator by using theProgram-
mingprocedures (regardless of where you live),replace
Programming HomeLinkstep 3with the following:
NOTE:If programming a garage door opener or gate
operator, it is advised to unplug the device during the
cyclingprocess to prevent possible overheating.
3. Continue to press and hold the HomeLink button
while youpress and release every two seconds(cycle)
your hand-held transmitter until the frequency signal has
successfully been accepted by HomeLink. (The indicator
light will flash slowly and then rapidly.) Proceed with
Programmingstep four to complete.

device may also be used at any time. In the event that
there are still programming difficulties or questions,
contact HomeLink at:www.homelink.com or 1-800-355-
3515.
