Do I still need to engage the electronic parking brake with auto hold?

Auto hold still requires engaging the electronic parking brake. Here are detailed introductions to both: Auto Hold System: Auto hold is an automatic braking function. When enabled, it provides better driving protection for the owner. At traffic lights, the auto hold function simplifies the owner's operation steps. Once activated, it eliminates the need to pull the handbrake. For automatic transmission vehicles, there's no need to repeatedly switch between D and N gears, making it convenient to use while enhancing driving safety. Electronic Parking Brake: The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both achieving parking control through the friction generated between the brake disc and brake pads. The only difference is that the control method has changed from the traditional mechanical handbrake lever to an electronic button.

I usually keep the auto-hold function activated while driving. It's really convenient during red lights or traffic jams - the car automatically brakes when coming to a complete stop, so I don't need to keep my foot on the brake pedal. There's absolutely no need to additionally engage the electronic parking brake in this situation, as the auto-hold already electronically locks the wheels. Of course, the electronic parking brake is an independent long-term parking function, which I typically only manually engage before turning off the engine and exiting the vehicle. Key point to remember: when auto-hold is active during driving, it's unnecessary to overcomplicate things - the two systems serve different purposes, with the former handling temporary stops and the latter designed for prolonged parking. Keeping auto-hold constantly activated for extended periods might actually affect battery life, something I've personally experienced.

After three years of driving a car with auto hold, my experience is clear: at red lights, auto hold handles everything without needing to touch the electronic parking brake button. The electronic parking brake is mainly used when completely stopping, such as when turning off the engine and leaving or parking on a steep slope, where manual activation is necessary. Auto hold and electronic parking brake are fundamentally two different mechanisms; the former relies on ESP for temporary braking, while the latter physically locks the wheels. Using both simultaneously can unnecessarily burden the vehicle's computer. Especially on downhill sections, auto hold automatically maintains braking pressure, reacting more promptly than manually engaging the electronic parking brake. However, on wet or snowy roads, I recommend using the electronic parking brake for added security.

When the auto hold is activated, there's no need to additionally engage the electronic parking brake. In my daily driving, simply pressing the brake pedal firmly at a red light triggers the auto hold, and a green light on the dashboard indicates it's locked. The electronic parking brake is an independent parking system, typically used when parking in P gear or turning off the engine. These two functions complement each other without conflict, but overlapping operations are completely unnecessary. The key point is: auto hold is controlled by an intelligent program, which adjusts the braking force in real-time through sensors, making it more precise than manual operation. Additionally, when starting on a steep slope, the auto hold can automatically coordinate with the throttle release, making the operation smoother and more natural compared to the electronic parking brake, which is particularly practical.

When using Auto Hold for red lights or temporary stops, there's really no need to additionally engage the electronic parking brake. My driving habit is: rely solely on Auto Hold for short-term stops, and only engage the electronic parking brake for stops exceeding 3 minutes or when leaving the vehicle. Their working principles are actually different - Auto Hold uses the ABS pump to maintain hydraulic braking force, while the electronic parking brake physically locks the calipers. Using both simultaneously may cause delayed brake system response, creating potential safety hazards. Especially during reverse parking, Auto Hold can automatically release the brakes for fine adjustments, making it much more flexible than the electronic parking brake which requires manual release. However, note that some models require seatbelt fastening to activate Auto Hold - I've experienced situations where unfastening the seatbelt automatically switched back to the electronic parking brake.
