If you don’t touch the screen for two minutes, iPad locks itself. You can change how long iPad 

waits to lock itself, or set a passcode to unlock iPad.
Set the auto-lock time. Go to Settings > General > Auto-Lock.
Set a passcode. Go to Settings > Passcode.
An iPad Smart Cover or iPad Smart Case, sold separately, can lock or unlock iPad for you (iPad 2 

or later).
Set your iPad Smart Cover or iPad Smart Case to lock and unlock iPad. Go to Settings > 

General, then turn on Lock/Unlock.

Home button

The Home button takes you back to the Home screen at any time. It also provides other 

convenient shortcuts.

Go to the Home screen. Press the Home button.
On the Home screen, tap an app to open it. See 

 on page 21.

See apps you’ve opened. Double-click the Home button when iPad is unlocked, then swipe left 

or right.
Use Siri (iPad 3rd generation or later). Press and hold the Home button. See 

 on page 47.

You can also use the Home button to turn accessibility features on or off. See 

 on page 130.

On iPad models with Touch ID, you can use the sensor in the Home button, instead of using 

your passcode or Apple ID password, to unlock iPad or make purchases in the iTunes Store, 

App Store, and iBooks Store. See 

 on page 43. You can also use the Touch ID sensor for 

authentication when using Apple Pay to make a purchase from within an app. See 

 on 

page 40.

Volume buttons and the Side Switch

Use the Volume buttons to adjust the volume of songs and other media, and of alerts and sound 

effects. Use the Side Switch to silence audio alerts and notifications or to prevent iPad from 

switching between portrait and landscape orientation. (On iPad models without a side switch, 

use Control Center.) 

For important information about avoiding hearing loss, see 

 on page 157.
