What do res+ and set- mean on Volkswagen cars?
2 Answers
The res+ and set- buttons on Volkswagen cars are mainly used for the cruise control function. res is the abbreviation of the English word reset, meaning "reset, return to zero", while set means "set". res+ reset function: The reset function is used to restore the set speed after canceling the cruise control, and it can also be used to increase the speed and reset the speed after setting the speed. For example, when the car is driving at a speed of 120 kilometers per hour, pressing res+ can maintain the speed at 120 kilometers per hour for continuous driving. set- set function: The set function allows the cruise control speed to be reduced according to the speed set by the owner. For example, when the car is driving at a speed of 120 kilometers per hour and wants to reduce the speed to 100 kilometers per hour, pressing set- can adjust the speed in the cruise control state.
I've been driving a Volkswagen for several years, and the res+ and set- buttons are commonly used in the cruise control system. When I activate cruise control on the highway, pressing set- can lower the speed setting, for example, from 120km/h to 110km/h, which is simple to operate and saves fuel; res+ is for resuming or increasing speed—sometimes after interrupting cruise control, pressing it returns to the last set value. This system makes long-distance driving much easier, allowing me to take my foot off the accelerator and focus on the road, especially useful when traffic is steady. However, beginners should remember to manually turn off cruise control in rainy, foggy weather or complex road sections to prevent sudden situations. Volkswagen's button placement on the steering wheel is very ergonomic and responsive, and I rely on it to improve efficiency every time I travel for work—just don’t over-rely on it to avoid developing lazy driving habits, as safety always comes first.
