NOTE:The default for the compass variance is zone 8.
To set the variance: Turn the ignition ON and set the
display to “Compass/Temperature.” Press and hold the
RESET button approximately five seconds. The last vari-
ance zone number will be displayed. Press the STEP
button to select the new variance zone and press the
RESET button to resume normal operation.
Outside Temperature
Because the ambient temperature sensor is located un-
derhood, engine temperature can influence the displayed
temperature, therefore, temperature readings are slowly
updated when the vehicle speed is below 20 mph (30
km/h) or during stop and go driving.
GARAGE DOOR OPENER — IF EQUIPPED
The HomeLink Universal Transceiver replaces up to
three remote controls (hand held transmitters) that operate
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 vehi-
cle’s battery and charging system; no batteries are needed.

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 and do 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 the Gate Operator/Canadian Pro-
gramming section.
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 light stays on
constantly, programming is complete and your device
should activate when the HomeLink button is pressed
and released. NOTE:
To program the remaining two HomeLink but-
tons, begin with Programmingstep two. Do not repeat
step one.
If the indicator light blinks rapidly for two seconds and
then turns to a constant light, continue with Program-
ming  steps 6-8 to 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 the learnorsmart button. This
can usually be found where the hanging antenna wire is
attached to the motor-head unit.
7. Firmly press and release the learnorsmart button.
(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 release the programmed HomeLink button.
Repeat the press/hold/release sequence 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 with Programmingstep two. Do not repeat
step one . For questions or comments, please contact
HomeLink at www.homelink.com or 1-800-355-3515 .
Canadian Programming/Gate Programming
Canadian radio-frequency laws require transmitter sig-
nals to time-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 to
time-outin the same manner.
If you live in Canada or you are having difficulties
programming a gate operator by using the Program-
ming  procedures (regardless of where you live), replace
 Programming HomeLink step 3 with the following:
NOTE: If programming a garage door opener or gate
operator, it is advised to unplug the device during the
 cycling process to prevent possible overheating.
3. Continue to press and hold the HomeLink button
while you press 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
 Programming step four to complete.

Using HomeLink
To operate, simply press and release the programmed
HomeLink button. Activation will now occur for the
trained device (i.e. garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc.). For convenience, the hand-held transmitter of the
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 .
Erasing HomeLink Buttons
To erase programming from the three buttons (individual
buttons cannot be erased but can be reprogrammed-
note below), follow the step noted:
•Press and hold the two outer HomeLink buttons until

Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down, or the sunroof (if equipped) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the rear windows open, open the front and rear windows
together to minimize the buffeting. If the buffeting occurs
with the sunroof open, adjust the sunroof opening to
minimize the buffeting or open any window.
Sunroof Maintenance
Use only a non-abrasive cleaner and a soft cloth to clean
the glass panel.
Sunroof Fully Closed
Press the switch forward and release to ensure that the
sunroof is fully closed.
ELECTRICAL POWER OUTLETS
The auxiliary electrical outlet can provide power for in
cab accessories designed for use with the standard “cigar
lighter” plug. The outlet is located in the instrument
panel below and to the right of the Climate Control
Panel. A cap is attached to the outlet base indicating
“Power Outlet” 12V-20A.
There is an additional Power Outlet inside the center
console of vehicles equipped with 40/20/40, or Bucket
front seats. There is also a Power Outlet located on the
rear of the center console for Quad Cab or Mega Cab
vehicles (only) equipped with bucket seats.
152 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The outlet(s) has/have a fused direct feed from the
battery so it/they receive power whether the ignition is
ON or OFF.
All accessories connected to this/these outlet(s) should
be removed or turned OFF when the vehicle is not in use
to protect the battery against discharge.
NOTE: If desired, all of the power outlets can be
converted by your authorized dealer to provide power
with the ignition switch in the ON position only.CAUTION!
Electrical Outlet Use With Engine Off
•Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent engine
starting.
•Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these intermit-
tently and with greater caution.
•After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle’s battery.

CAUTION!
•Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not
in use (i.e. cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
•Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
•After the use of high power draw accessories, or
