If you overheat for a certain amount of time the engines will break.
How to avoid engine overheat.
Before takeoff, click the top of a thrust index gauge (below) & it will set the correct index for you (yellow number).
When it reaches 100% on this gauge that should be all the power you need, assuming it's a decent sized runway.
If you can't reach 97% you're grounded, unless no one is looking.
Another way is to turn on Top Temp (in the VC)

With this set it's impossible to overheat.
You can apply full power & it will automatically reduce fuel flow if it thinks you've set it too high.
The auto pilot in the 510ED is similar to the Trident, but the AP in the other 1-11s is not as sophisticated.
The standard AP only has an altitude lock, not acquire, so you can't set an altitude.
It will only hold whatever the current altitude was when it ALT mode was activated.
It doesn't have autothrottle or IAS mode either.
It does have a full 'MANUAL' mode though, so as soon as it is engaged you can adjust pitch with the pitch thumb wheels and adjust roll with the 'TURN' knob.
