Euro Truck Simulator 2 (ETS2) just got another improvement on the 1.37 update. Now you can open side windows and enjoy more immersive ambient environment when driving — no mod required.
The following guide will show you how to open side windows on Euro Truck Simulator 2. Make sure you already have version 1.37 or above installed beforehand.
Go to the pause menu and select Options.
Head to Keys & Buttons.
Assign keys for the following selection.
Back to game and try to open the windows.
You may also press and hold the open/close button to half-open.
When the windows are open, the noise level will be significantly higher. However, keeping windows open during rain can be useful to avoid droplets covering the mirror’s view. You might want to check out the truck and ambient noise on the “Settings” menu.
Also, check out my previous tutorial on how to remove the 90km/h speed limit on ETS2 so you can deliver the cargo faster!
