What do RES+ and SET- mean on a car?
2 Answers
RES+ and SET- are paddle shifters for manual-automatic transmission models. When the gear lever is in the manual position, you can directly use the paddles - the plus sign is for upshifting, and the minus sign is for downshifting. RES: RES has two functions: one is to resume the set speed after temporarily canceling cruise control, and the other is to accelerate to the set speed after setting the cruise control speed. SET: SET also has two functions: one is to decelerate to the set speed after setting the cruise control speed, and the other is to set the current speed as the cruise speed.
My car also has the RES+ and SET- buttons, which are used for the cruise control system. RES+ stands for "resume," meaning it restores the previously set speed—for example, if you brake temporarily to slow down, pressing it will return the car to the original preset speed. SET- stands for "set minus," helping you set or reduce the current speed. Pressing it locks the car at the current speed or slightly decreases it. This feature is particularly useful for highway or long-distance driving, as it automatically maintains a stable distance and reduces fatigue from constantly pressing the accelerator. Remember, the operation is simple: first press SET- to lock the speed, then press RES+ to resume after slowing down. However, designs may vary across different car models—my experience is that similar button systems can be found in everything from basic to luxury vehicles.
