Appendix C Safety, Handling, & Support 149
If the interior temperature of iPhone exceeds normal operating temperatures (for example, in a
hot car or in direct sunlight for extended periods of time), you may experience the following as it
attempts to regulate its temperature:
•
iPhone stops charging.
•
The screen dims.
•
A temperature warning screen appears.
•
Some apps may close.
Important: You may not be able to use iPhone while the temperature warning screen is
displayed. If iPhone can’t regulate its internal temperature, it goes into deep sleep mode until
it cools. Move iPhone to a cooler location out of direct sunlight and wait a few minutes before
trying to use iPhone again.

Restarting or resetting iPhone
If something isn’t working right, try restarting iPhone, forcing an app to close, or resetting iPhone.
Restart iPhone: Hold down the Sleep/Wake button until the red slider appears. Slide your finger
across the slider to turn off iPhone. To turn iPhone back on, hold down the Sleep/Wake button
until the Apple logo appears.
Force an app to close: Hold down the Sleep/Wake button for a few seconds until a red slider
appears, then hold down the Home button until the app closes.

If you can’t turn off iPhone or if the problem continues, you may need to reset iPhone. A reset
should be done only if turning iPhone off and on doesn’t resolve the problem.

at least ten seconds, until the Apple logo appears.
