## What is FST?

FST Smart Climate gets the cabin ready before you get in, and keeps adjusting while you drive.

PRECONDITIONING
• Set a target and precondition the cabin (precool or preheat) with Shortcuts or a tap.
• Auto climate can start on its own. If nobody gets in within the countdown, climate turns off.

LIVE ACTIVITIES

• Watch the shutoff countdown while preconditioning.
• See Camp Mode and temperature hold at a glance.

SHORTCUTS

• Add place and time rules, including scheduled climate routines.
• Put the action on Control Center, Action Button, or Lock Screen.

COMFORT
• Learns from the temperatures you pick.
• Tweaks the target as outdoor conditions change on the road.
• Keeps a history of preconditioning and adjustments.

PRIVACY
Review data practices, export your data, withdraw vehicle authorization, or delete your account in the privacy center.

REQUIREMENTS
