Thank you for your question, my name is Steve and I am a fully qualified vehicle technician with over thirty years in the trade hopefully I can help.
To turn off the internal sensor when leaving an animal in the vehicle: On vehicles without smart entry &
start system: Turn the engine switch to the "LOCK" position and press the intrusion sensor (as attached diagram)
Vehicles with smart entry & start system: Turn the START STOP" switch off and press the intrusion sensor cancel switch, Pressing the switch again will re-enable the sensor.
This needs to be done eveytime the vehicle is exited and the sensor needs to be disabled.
