▼Gate operator/Canadian
Programming
Canadian radio-frequency laws require
transmitter signals 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-out” in the same manner.

If you live in Canada or are having
difficulties programming a gate operator
by using the programming procedures
(regardless of where you live), replace
Step 3 of Programming the HomeLink
System 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.
While the indicator light is flashing in
amber, press the button on the hand-held
transmitter for 2 sec onds and release it
repeatedly until the indicator light changes
from amber to green.
Go back to Step 4 of Programming the
HomeLink System to complete the
procedure.
▼ Operating the HomeLink System
Press the programmed HomeLink button
to operate a programmed device.
▼ Reprogramming the HomeLink
system
To program a device to HomeLink using a
HomeLink button previously trained,
follow these steps:
1. Press and hold the desired HomeLink
button. DO NOT release the button.
2. After 20 seconds, the indicator light flashes in amber. After the indicator
light flashes, release the HomeLink
button.
3. Go back to Step 2 of Programming the HomeLink System to complete the
procedure.
NOTE
If the programming has not been
completed, the syst em returns to the
previous programming.
▼ Erasing Programmed HomeLink
Buttons
NOTE
All of the programmed HomeLink
buttons are reset.
Individual buttons
cannot be reset, however, individual
buttons can be reprogrammed. For
individual button reprogramming, refer
to Reprogramming the HomeLink
System (page 4-60).
Verify that the programming has been
erased if you resell the vehicle.

The RCTA system is des
igned to assist the
driver in checking the area to the rear left
and right sides of your vehicle while your
vehicle is reversing by alerting the driver
to the presence of vehicles approaching
the rear of your vehicle.
The RCTA system detects vehicles
approaching from the rear left and right

WA R N I N G
Always check the surrounding area visually
before actually putting the vehicle in
reverse:
The system is only designed to assist you in
checking for vehicles at the rear when
putting the vehicle in reverse. Due to
certain limitations with the operation of
this system, the Blind Spot Monitoring
(BSM) warning indicator lights may not
flash or it might be delayed even though a
vehicle is behind your vehicle. Always make
it your responsibility as a driver to check
the rear.

selector lever (automatic transmission)
is shifted to the reverse (R) position.
2. If there is the poss ibility of a collision
with an approaching vehicle, the Blind
Spot Monitoring (BSM) warning
indicator lights flashes and the warning
beep is activated simultaneously.
