5. Operating Instructions
Familiarize yourself with the remote control buttons and their functions. The two-way LCD remote provides visual feedback on the system's status.
Basic Operations:
- Arming the System: Press the lock button on your remote. The vehicle lights will flash, and the siren will chirp (unless silent arming is enabled). The LCD remote will display the armed status.
- Disarming the System: Press the unlock button on your remote. The vehicle lights will flash, and the siren will chirp twice. The LCD remote will display the disarmed status.
- Silent Arming/Disarming: Consult your full manual for specific button combinations to arm or disarm the system without audible chirps.

- Trunk Release: Press and hold the trunk release button on your remote.
- Car Finding (Panic Mode): Press the car finding button to activate the siren and flashing lights, helping you locate your vehicle.
- Valet Mode: Use this mode when your vehicle is being serviced. It temporarily disables the alarm functions while allowing remote start and keyless entry. Refer to the full manual for activation/deactivation steps.
- Shock Sensor Adjustment: The sensitivity of the two-level shock sensor can usually be adjusted via the remote or a dedicated button on the sensor itself.
- Remote Programming: If you need to add a new remote or reprogram existing ones, follow the detailed instructions in the complete manual. This typically involves entering a programming mode using the ignition key and then pressing buttons on the remotes.
