126 OPERATION Transmitter Operations The door transmitter has four buttons (labeled LOCK, UNLOCK, AUX and HORN) to control operation of the system. When any of the buttons is pressed, a coded Ultra-high frequency (UHF) radio signal is transmitted to the receiver in the vehicle.

The transmitter must be within approximately 10 meters (33 feet) of the vehicle for the receiver to detect the coded signal. The Remote Keyless Entry system has no affect on the normal operation of the power door locks.

When the LOCK button is pressed, the doors will lock and the lights will flash once indicating that the doors are locked. The dome light will be on for 5 seconds upon locking the door by remote. For audible confirmation of the door lock, press the LOCK button a second time and the horn will beep once to confirm the doors are locked.

When the UNLOCK button is pressed once, the drivers door will unlock and the lights will flash twice indicating that the door is unlocked. The dome light will be on for 30 seconds upon unlocking the door by remote. Pushing the UNLOCK button a second time within 3 seconds will unlock both doors.

Note: If AUTO RE-ARM feature is selected, the keyless entry system will automatically re-arm itself 60 seconds after the doors are unlocked with remote transmitter. Automatic re-arm will cancel if any door is opened before the 60 seconds timer has elapsed.

Press and hold the AUX button on the transmitter for 0.5 second to turn perimeter or trailer access lights "On" or "Off" (if equipped).

Press and hold the HORN button on the transmitter for 3 seconds. The horn will immediately sound and running lights will flash. During panic mode, the normal function of this transmitter button will be suspended. LOCK and UNLOCK buttons cannot be used to lock and unlock the doors. To stop the alarm, press and hold the HORN button on the transmitter again for 3 seconds.

If the button is not pressed, the alarm will automatically stop after 60 seconds.
