Grok can now handle most of the things Tesla owners used to do with the car's older voice commands, and quite a few things those commands couldn't, Not a Tesla App reported, drawing on testing by Tesla owner @LifeMiddie, who tried 172 voice commands. At the latest count, Grok supports 119 of them, while the other 53 still require pressing the mic button and using Tesla's older voice system.
Grok first arrived in Tesla vehicles in the United States with software update 2025.26 as a conversational assistant. Tesla then added navigation commands in the 2025 Holiday Update, letting drivers describe where they wanted to go instead of reciting addresses. The Spring 2026 Update added the "Hey Grok" wake word and location-based reminders, and this year's Summer Update gave Grok control over vehicle functions like climate, seat heating and settings, the site reported. Grok is now available across North America, Europe, Australia, and most of Asia and the Middle East.
To use these commands, you'll need a vehicle with an AMD Ryzen infotainment computer and either Premium Connectivity or a Wi-Fi connection. It isn't available on Intel Atom-powered vehicles. Not a Tesla App noted that update 2026.38 quietly added Grok files to Intel Model 3 and Model Y vehicles, but that is not the same as a confirmed, working rollout on those older computers. Grok also needs to be set to the Assistant personality. Just say "Hey Grok" to get started. According to @LifeMiddie, "Hey Bro" works as a wake word too.
Climate controls are among the most useful commands: "Set climate to 68," "Set fan speed to low," "Turn on Dog Mode" (Camp Mode and Climate Keeper work too), "Recirculate air," "Turn on all seat heaters," "Turn on all seat heaters except for the driver's," and "Defrost the windshield." Grok cannot control heating for the rear seats, only the driver's and front passenger's. Saying "I'm cold" raises the temperature by 3 degrees Fahrenheit, while "I'm hot" lowers it by 3. Grok can also aim the vents, sync or split driver and passenger temperatures, turn on the heated steering wheel, and turn on Bioweapon Defense Mode, the report said.
For navigation, you can say "I'm hungry," "Show nearby Superchargers," or "Let's go home," turn Avoid Tolls, Avoid Ferries or HOV lanes on or off, and cancel navigation. A location-based reminder such as "Remind me to charge when I get home" alerts you once you're within about 1,600 feet of your destination. Grok can place calls, play a song, artist or playlist, and switch among Spotify, TuneIn, Tidal, Bluetooth, USB and radio. It can't pause music, but it will resume playback if the music is already paused. It can open the Browser, Energy app, Calendar, Netflix, YouTube, Tesla Arcade and Tesla Theater, and can load a website and read an article aloud.
It can also open the glovebox and charge port door, fold the mirrors, turn on Sentry Mode, save Dashcam clips, control the dome lights, show the backup camera, set the wipers to auto, read tire pressures or the odometer, and open the owner's manual. You can chain requests in one sentence. What it still cannot do includes locking or unlocking the doors, opening the trunk or frunk, adjusting air-suspension ride height, changing acceleration mode, turning on Car Wash Mode, or adjusting the mirrors and steering wheel. Hands-free texting is already listed in Tesla's owner's manual but has not necessarily shipped. Musk said in June that owners would be able to control FSD with Grok, including asking to park near a door; that feature has not arrived yet, Not a Tesla App reported.
