Zoom lenses - stuck in its housing or fully extended are caused by factors like - knocks, dead butteries debris or some form of corrosion . This is a risky method and I would recommend for the last option, if other conventional methods don't work. Provided your lens has collapsed into its housing - you try a little knock on the camera with your palm while pressing the on/off button. If that does not work, you are on your own - to decide.

Maybe it has a battery for the date settings, and the battery is faulty.

Unfortunately, there is no viewfinder dioptric adjustment on this model. You will need to wear your glasses.

Most often when this happens, it is, as you\'ve stated, a battery, but it might also be a corroded battery connection. You can use an eraser, or if its physically obvious, try a tiny piece of fine sandpaper, but use it gently, only to clean off corrosion. It may also be that your camera was dropped and a soldered circuit connection damaged, or it might have been exposed to penetration of moisture. The best thing you can do is 1. Give it time, say a month, to dry out, and 2. Send it in for an examination by Canon, being sure you tell them you\'ll need a repair estimate to ensure it is cost effective.
