What is the RES function in BMW?
2 Answers
In the BMW 5 Series, RES stands for adjusting speed. Below is extended information about car buttons: 1. Buttons: There are three buttons and one dial on the left side of the steering wheel. The three buttons are SET, RES, and I/0, all of which control the cruise control function. 2. Functions: SET sets the current speed as the cruising speed, RES recalls the cruising speed before the cruise control was interrupted, I/0 turns the cruise control function on or off, and the dial adjusts the cruising speed. The core technology of the all-wheel drive system is the transfer case developed by Magna Steyr in Austria, which continuously adjusts torque distribution.
I've driven BMWs for many years, and the RES function is quite handy, especially on long highway trips. It's part of the cruise control system, standing for Resume, which means restoring the previously set speed. For example, if you set the cruise speed to 100 km/h, and then hit the brakes or use the cancel button to pause it, when the road conditions improve, pressing the RES button will automatically accelerate the car back to the preset speed. This makes driving much easier, as you don't have to constantly watch the dashboard or press hard on the accelerator. BMW's system is well-integrated; the adaptive cruise control combined with RES can also automatically adjust the distance to the car ahead. The benefits include fuel savings, reduced driver fatigue, and higher safety. The button is usually located on the right side of the steering wheel, making it simple and intuitive to operate, but be careful not to misuse it in heavy traffic. A few practice runs will get you familiar with it.
