How to Prevent Setting Off Sentry Mode Alarm When Parked and Waiting in Model 3? Will It Set Off?

How to Prevent Setting Off Sentry Mode Alarm When Parked and Waiting in Model 3? Will It Set Off?

Ok,

If I am driving the Tesla Model 3 with a passenger, I get out of the car and walk away, will the car activate the Sentry Mode alarm automatically even though there is a passenger in the passenger seat? Or will it detect a passenger due to the passenger's weight and not set off the Sentry Mode alarm if the passenger is knocking around inside the car?

I don't want my passenger to go deaf by accidentally setting off the Sentry Mode alarm.

Do I have to go through the car's LCD screen menu (or the phone app) to turn off the Sentry Mode manually or will sentry mode turn off automatically if it senses the weight of a person sitting on the car's seat?

It seems like a PITA to have to turn off the sentry mode manually every time you leave a waiting passenger in the car. Also, the danger is that I forget to turn off sentry mode if I leave behind a waiting passenger in my car. I work on the South side of town where there is high crime so I want to just leave the sentry mode on and forget about it.

I read the faq after the OTA update and I saw half a dozen youtube videos but it is still not clear.

Thanks.

I'm not 100% sure since I just got the update last night but it seems you have to enable Sentry Mode each time you put the car in park (P) - either via screen or Tesla app on phone. I thought it was a bug in the software but I believe it's to prevent concerns like yours.

ahh... i found tesla raj's youtube post and you're right, you have to turn it on every time or it will be off by default.

Yes when you go out the car will activate Sentry Mode and it will trigger the alarm if you have people waiting in the car. I have experienced this myself and it scared my sisters who were waiting in the car.

My wife recently left the car to pay for parking. The alarm was activated when her phone disconnected and the passenger inside set off the alarm. It was really loud and scary. We’ll be more cautious in future but would be good to know if there is a way to avoid this from happening again.

The passenger can turn off Sentry Mode using the icon on the touchscreen. I think it’s odd that Sentry Mode goes on as soon as you put the car in park, before getting out.

That said, how did the passenger set off Sentry Mode? It definitely does not respond to motion inside the car.

Hi EVRider. I don’t know how it was set off. I had assumed that my passenger had moved and that’s what set it off. My wife was parked in a car park and there was no outside reason to set off the alarm. Could it really be a coincidence that the alarm went off the only time that we left someone in the car with Sentry mode on.

This is actually still a big issue in my opinion.
This has happened three times (at least) for me, one when I as the driver put the car in parking mode, locked the car and then started Netflix and when I moved to get something the alarm went off.
Second time when I went to get a takeaway coffee and let my dog in the car, alarm went off.
Third time yesterday, kids did not want to go with me into the store as they were playing on their phones, alarm went off again. In none of the cases where a door involved, the alarm went off just by movement in the car and it is not that you are jumping in the car either, it takes really little to set the alarm off.

A smart car like this should really know when there are people still inside the car, with or without it being locked.

I want to report this as a bug so I will go ahead and try that.

@cello: I’ve sat in the car with Sentry Mode on and never set anything off. Sentry Mode doesn’t use a motion sensor inside the car. Do you also have the intrusion alarm system?

I too think this is an issue. However, my own daughter set of the alarm after I left the car to shop but it wasn't crazy loud and sounded only shortly, as far as she reported. It sent a message to my phone and I was at the car a minute later - hearing nothing.

@EVRider: You have sat in the car with sentry mode on and not triggered the alarm... because you have the phone key, I assume.

EVRider | 28 maggio 2020

@Sally: I did have the key, and I just checked the manual and it implies that Sentry Mode is only active when the car is locked, so that explains the difference. The Sentry Mode icon turns red even when the car isn’t locked, so that threw me off.

Even so, I don’t think there are any motion sensors in the car unless you have the optional Tilt/Intrusion Sensor package, so I’m still puzzled by some of these reports.
