Comfort and Convenience
Power mirrors move the glass by small motors from a door switch, so the aim can be corrected while seated. They set viewing angle only, not how much of the car's flank stays visible.
Safety and Driver Assistance
When a driven wheel spins up on wet or loose surfaces, ASR trims engine torque and can brake that wheel. It only restores grip already available; it cannot create traction on ice.
Multimedia and Connectivity
A USB port confirms a physical socket for connecting and charging a phone. Whether music files, folder browsing or a particular handset are read depends on the head unit's supported formats.
