Controls Safety Driving tips General maintenance Self-help Technical data
At the operating unit
1. Switch on the ignition (do not start the engine).
2. Press and hold down the two outer HomeLink buttons
⇒ page 154, fig. 171 until the indicator diode
⇒ page 154, fig. 171 begins to flash after about
20 seconds. This procedure will delete the standard
factory settings and does not need to be repeated when
programming the other buttons.
3. Press the particular HomeLink button which you would
like to program.
4. Wait until the diode begins to flash. The HomeLink
module now remains in training mode for 5 minutes.
5. Now step in front of your vehicle with the original hand-
held transmitter for the garage door opener or any other
device you wish to assign to the HomeLink control
button.
At the radiator grille
6. Hold the original hand-held transmitter at or near the
centre of your car's radiator grille ⇒ page 154, fig. 172.
7. Press the activator button on the original hand-held
transmitter.
8. As you do so, watch the turn signals on your vehicle.
HomeLink confirms successful programming by flashing
all four turn signals three times.
9. If the turn signals fail to flash three times, repeat the
procedure with the transmitter held at a different
distance from the radiator grille.
The proper distance between the hand-held transmitter and the
HomeLink module at the radiator grille depends on the system you
want to train. It may require several attempts.
The turn signals will flash once if the time limit for the programming
mode has been exceeded. In this case the programming procedure
needs to be performed again. Repeat the sequence at the operating
unit starting with step 3.
The programming instructions above also apply to the other control
buttons. Start with step 3 if you wish to proceed and program the
other two buttons.
If the garage door or other devices still fail to be activated with the
HomeLink control buttons after programming is completed, it is
possible that these systems might be working with a rolling code
instead of the normal fixed security code. If this is the case, a rolling
code programming is required in addition to the steps described
above. ⇒ page 155
Applies to vehicles: with HomeLink
Rolling code programming
Some devices require rolling code programming of the
HomeLink universal transmitter.
Identifying a rolling code
– Press the already programmed HomeLink button again
and hold it down.
–Watch HomeLink diode ⇒ page 154, fig. 171. If the
diode starts flashing rapidly and turns into a constant
light after about 2 seconds, this indicates that the device
you wish to operate (e.g. a garage door opener) is
equipped with a rolling code.
– Program the rolling code as follows:
