If Model X does not detect a key nearby and a locked door or trunk is opened, an alarm sounds. The headlights and turn signals also flash. To deactivate the alarm, press any button on the key fob.

To manually enable or disable the alarm system, touch Controls > Safety > Security Alarm. When enabled, Model X activates its alarm one minute after you exit, the doors lock, and a recognized key is no longer detected.

A battery-backed siren (if equipped) sounds in situations where a locked door or trunk is opened and Model X does not detect a key nearby. If you also want this siren to sound in situations where the vehicle detects motion inside the cabin, enable Tilt/Intrusion (see Tilt/Intrusion (if equipped)).

Depending on configuration, market region, and date of manufacture, your vehicle may not be equipped with this feature.

The Security Alarm must be on to enable Tilt/Intrusion.

Tilt/Intrusion sounds the alarm in your vehicle if Model X detects motion inside the cabin, or is moved or tilted (for example, with a tow truck or jack). To enable, touch Controls > Safety > Tilt/Intrusion.

The intrusion sensor automatically disables in situations where the climate control system is operating when you leave your vehicle. To override, you can manually turn the Tilt/Intrusion Sensor on again after choosing Keep Climate On, Dog, or Camp Mode.

The tilt/intrusion sensor automatically re-enables at the start of every drive cycle.

If your vehicle is equipped with the Enhanced Anti-Theft upgrade, the horn sounds in situations where a locked door or trunk is opened and Model X does not detect a key nearby. If Tilt/Intrusion is on, the horn also sounds if Model X detects motion inside the cabin or if the vehicle is moved or tilted (for example, with a tow truck or jack). To turn the Tilt/Intrusion detection system on or off, touch Controls > Safety > Tilt/Intrusion.

For an added layer of security, prevent Model X from being driven until a 4-digit PIN (Personal Identification Number) is entered. To enable this setting, touch Controls > Safety > PIN to Drive and follow the on-screen prompts to create a driving PIN.

When enabled, in addition to entering the 4-digit driving PIN to drive, you must also use it to enter Valet mode for the first time and create the 4-digit valet PIN to enter and exit Valet mode. In Valet mode, Model X can be driven without the need for the valet to enter a driving PIN. The PIN to Drive setting is disabled whenever Valet mode is active.

If you forget your driving PIN, touch the link to enter your Tesla login credentials on the PIN to Drive popup, then follow the instructions on the touchscreen.

Protect the contents in your glovebox with a 4-digit PIN (not related to PIN to Drive). To enable, touch Controls > Safety > Glovebox PIN and follow the directions on the touchscreen. When enabled, you are prompted to enter the PIN to open the glovebox. Select the toggle to disable and then enter the PIN to remove this added security protection.

If you forget your glovebox PIN, reset it by entering your Tesla login credentials, then follow the directions on the touchscreen.

Speed Limit Mode allows you to limit acceleration and maximum driving speed to a chosen value between 80 and 193 km/h. The first time you use this feature, you must create a 4-digit PIN that you must use to enable and disable Speed Limit Mode. When enabled and the driving speed approaches within approximately 5 km/h of the maximum speed, a chime sounds, the instrument cluster displays a message, and Model X sends a notification to the mobile app. You can also touch Security > Speed Limit Mode to enable from the Tesla mobile app. To enable Speed Limit Mode:

You can clear your vehicle's browser data (like you would on a computer or smartphone) by navigating to Controls > Service > Clear Browser Data. This is useful for many situations, such erasing settings or searches from another driver.

Check the boxes on the touchscreen popup to exclude bookmarks and/or history for your convenience.
