Temperature question

[megathunder1]

Hello i have a 2015 Mercedes cla45 amg.



I was wondering if anyone knew what the safe operating temperatures of the 3 icons in the middle are (Engine, Cooling and Transmission)

I can't answer specifically for the A45, but on a general note:

Engine oil optimal operating temperature is 90-110⁰C.

Coolant is 87-103⁰C (depending on the thermostat's rating).

Automatic transmission is 80-95⁰C.
