The first time your iPhone running iOS 11 senses that you might be driving, it shows a description of the Do Not Disturb while driving feature after you stop. (This description appears only in certain countries; if it doesn't appear, follow the steps below to enable the feature.)
Tap Turn On While Driving, and it will turn on automatically when your iPhone connects to your car via Bluetooth* or when your iPhone senses driving motion. You can change the method your iPhone uses to determine whether you're driving, or turn the feature on manually.
*If your car supports CarPlay and you connect your iPhone, Do Not Disturb while driving is not automatically activated.
Turn it on and off in Control Center
You can let Do Not Disturb while driving turn on automatically, or you can add it to Control Center for convenient manual access:
- Go to Settings > Control Center > Customize Controls.
- Tap next to Do Not Disturb While Driving.
Now you can swipe up from the bottom of your screen and tap to turn the feature on or off.
What to expect while it's active
Here's what to expect when Do Not Disturb while driving is turned on. You can customize many of these features in Settings.
- Your iPhone stays silent and the screen stays dark. If someone sends you a message, they receive an automatic reply letting them know that you're driving. If the message is important, the sender can type the word "urgent" to make sure that you receive a notification. Then you can pull over to read their important message or ask Siri to read it to you.
- iPhone delivers some notifications, such as emergency alerts, timers, and alarms.
- Phone calls are delivered using the same conditions as standard Do Not Disturb: You can allow calls only from your Favorites, and allow calls to come through if the same person calls twice in a row. If your iPhone connects to your car via Bluetooth, calls will come through as usual, and you can use your car's buttons, microphones, and speakers to take your call.
- If you use Maps to navigate, your iPhone still shows lock-screen navigation help and gives turn-by-turn instructions.
- If you're a passenger and you try to use your iPhone while the feature is active, you must tap I'm Not Driving to turn it off.
Customize its features
You can customize how Do Not Disturb while driving works in Settings > Do Not Disturb.
Tap Activate to choose how you'd like Do Not Disturb while driving to turn on.
- Automatically: Your iPhone uses information like motion detection and network connections to sense that you might be driving, and turns the feature on.
- When Connected to Car Bluetooth: Do Not Disturb while driving starts when your phone connects to your car's hands-free system.
- Manually: Use Control Center to turn on Do Not Disturb while driving before you begin.
Tap Auto-Reply To and choose who receives an auto-reply, then tap Auto-Reply to customize the message they receive. If someone still needs to contact you, they can break through Do Not Disturb by sending "urgent" as an additional message.
Use Restrictions to keep it on
Are you the parent of a young driver? You can prevent changes to Do Not Disturb while driving to make sure that it remains a part of their safe driving habits.
- On your child's iPhone, go to Settings > General > Restrictions.
- If you haven't used Restrictions before, enter a new passcode. Remember this passcode for any future changes.
- Under Allow Changes, tap Do Not Disturb While Driving.
- Select Don't Allow Changes.
