Switching drivers? Use memory presets to set seat and mirrors in one go.

You’ll notice the numbers 1, 2, 3 and the letter M on the power-seat controls. M stands for Memory—it lets you save your preferred seat and side-mirror positions to a number and recall them automatically.

If you look on the left side of the driver’s seat (or the right side of the front passenger seat), you’ll find the seat-adjustment switches along with the memory buttons. (If your car doesn’t have power seats, or it’s an older model, this feature may not be available.)


How to use seat & side-mirror memory

  1. Manually adjust the seat and side mirrors to where you want them.
  2. Press and hold the M button for about 3 seconds, then press 1 (or any number you want). You’ll hear a short beep to confirm it’s saved.
  3. To recall it, press and hold the saved number. The seat and mirrors will move to the stored position.

Notes & tips

  • If you try to save without changing anything, nothing will move later—adjust first, then save.
  • Apart from the confirmation beep, most cars won’t give a voice prompt or on-screen message. (Exact operation can vary by model.)

It’s very convenient, but if kids often ride in the front passenger seat, they may press the buttons out of curiosity. Sudden seat or mirror movement can be surprising and even risky, so consider disabling or avoiding the feature in that situation.


For cars shared by multiple drivers—or when you recline to rest in the car—memory presets are a lifesaver. If you have a sensitive back, save the position that feels best and bring it back with one press.


In tight spaces or narrow parking lines, angling a mirror down to see the ground or the line helps with accuracy. Instead of tweaking it every time, save a “parking” preset and call it up with a button.
