What do the E and P on the fuel-saving switch represent?

Vehicle's E/P switch is the electronic parking brake system. The following are the extended contents: 1. It calculates the slope through the built-in longitudinal acceleration sensor in its computer, so it can calculate the sliding force generated by gravity when the vehicle is on a slope. The computer applies braking force to the rear wheels through the motor to balance the sliding force, enabling the vehicle to stop on the slope. 2. The electronic parking brake system can ensure stable parking on a 30% slope. Additionally, the system automatically implements thermal compensation, meaning if the vehicle is parked after hard braking, the rear brake disc will create a gap with the friction pad due to temperature drop. At this time, the motor will automatically start, driving the compression nut to compensate for the gap caused by temperature drop, ensuring reliable parking effect.
I've always found the fuel-saving switch quite practical, especially the E and P modes—E stands for Economy mode, primarily designed for fuel efficiency. It adjusts the gear-shifting timing to keep the engine running at lower RPMs, significantly reducing fuel consumption during daily city driving while also being cost-effective on highways. P, on the other hand, represents Power mode, which delays gear shifts to enhance engine output, making overtaking or climbing hills particularly exhilarating. Personally, I use E mode for my daily commute—with fuel prices so high, it saves me hundreds annually—and switch to P mode on weekend getaways for stronger acceleration, effortlessly handling mountain roads. Remember to regularly check the switch's wiring to prevent loosening, ensuring stable system operation and a smooth driving experience.
