How to Use the RES and SET Buttons on the Steering Wheel?
2 Answers
Here are the instructions for using the RES and SET buttons on the steering wheel: 1. RES: The RES button is a resume key with two functions. One is to accelerate when the cruise control is set, and the other is to resume the previously set speed by pressing RES after temporarily canceling the cruise control. 2. SET: The SET button is a speed setting key with two functions. One is to decelerate when the cruise control is set, and the other is to set the current speed as the cruise speed by pressing SET after temporarily canceling the cruise control. 3. RES/+ and SET/-: RES/+ and SET/- are paddle shifters for manual-automatic transmission models. When the gear lever is placed in the manual position, you can directly use your hands to operate the paddles. The one with a plus sign is for upshifting, and the one with a minus sign is for downshifting.
The 'res' and 'set' buttons on this steering wheel are common features in cruise control systems. I've driven many cars, and they all function this way. 'res' stands for 'resume,' which means restoring the previously set speed; 'set' is for setting the current speed. For example, when driving on the highway and you want to maintain a speed of 100 km/h, first accelerate to that speed, then press the 'set' button—it locks in, and your foot doesn't need to press the accelerator as the car maintains the speed automatically. If you brake or cancel the cruise control midway, pressing 'res' will immediately restore the 100 km/h setting, making long drives fuel-efficient and effortless. Some cars also have speed adjustment buttons—pressing '+' or '-' allows fine-tuning of the speed. It's best used on highways with light traffic and good weather. Beginners should take time to adapt, stay focused on steering, and prioritize safety—avoid using it in urban areas or slippery conditions. I've seen many cases where misoperation nearly caused rear-end collisions. Regularly check button responsiveness and system updates to prolong its lifespan.
