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.

RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the operation of a cellular
phone in your vehicle can cause erratic or noisy perfor-
mance from your radio. This condition may be lessened
or eliminated by relocating the cellular phone antenna.
This condition is not harmful to the radio. If your radio
performance does not satisfactorily “clear” by the repo-
sitioning of the antenna, it is recommended that the radio
volume be turned down or off during cellular phone
operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
