Can Auto Hold and Engine Start-Stop Be Used Simultaneously?

[DiVivienne]

Auto Start-Stop is used for stopping and starting the engine, while Auto Hold is used for stabilizing the vehicle after stopping. These are two completely different functions that can be used together. More details are as follows: 1. Engine Auto Start-Stop: The engine automatically shuts off when the vehicle comes to a temporary stop during driving and restarts automatically when it's time to move forward. 2. How the Auto Start-Stop System Works: When the driver stops the vehicle by pressing the brake pedal and shifting to neutral, the Start/Stop system automatically detects that the engine is idling and in neutral. The wheel speed sensor of the locking system shows zero, and the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine shuts off automatically. When the driver releases the brake or turns the steering wheel, the engine restarts automatically. 3. Auto Hold: This is an automatic braking function. When activated, it automatically applies the handbrake for the driver at traffic lights to prevent the vehicle from rolling backward. 4. How It Works: It integrates temporary braking during driving with long-term braking after stopping, using electronic control to achieve parking brake technology. Note: These are two distinct functions. Some drivers may confuse them, such as pressing the Auto Start-Stop button when intending to use Auto Hold, leading to forgetting to apply the handbrake and causing the vehicle to roll.

As a veteran driver with over a decade of experience, I find this duo of features absolutely brilliant! Here's my routine: at red lights, simply lift your right foot off the pedal—auto hold instantly locks the brakes, allowing the start-stop system to safely shut off the engine. To start moving, just lightly tap the accelerator: the engine fires up instantly, the electronic parking brake releases automatically, and you won't need to shift gears or touch the brake pedal throughout the entire process. One crucial tip: remember to disable start-stop before wading through water in rainy conditions to prevent hydro-locking the engine. Master this combo, and you'll see urban commute fuel consumption drop by around 15%, with more red lights translating to greater savings.

Last time when accompanying a friend to pick up a new car, I specifically researched this issue. For mainstream models like Toyota and Volkswagen, the automatic parking and start-stop systems operate with coordinated logic. When you press the brake pedal deeply to trigger the engine stop, the automatic parking will automatically take over the braking. However, some models require the automatic parking to be activated first before the start-stop system becomes effective - you'll need to check the manual for specifics. Here's a lesser-known fact: For vehicles equipped with hill start assist, the combination of these two features can also prevent rollback, which is particularly useful for novice drivers. But do note that the start-stop function may be temporarily disabled when the air conditioning is under high load.

Here's a detail for new energy vehicle owners: Hybrid models get the best value when using both features together! The electric motor starts instantly as the auto-hold releases, completely avoiding the vibration from engine start-stop. Tested on BYD DM-i models - at red lights, the engine shutdown time is 30% longer than conventional fuel vehicles. Combined with regenerative braking, it saves 1L/100km in congested areas. Note: Sport mode usually disables start-stop automatically.

From a driving instructor's perspective, it's best for beginners to use these features separately initially. First get accustomed to the auto hold function to prevent rolling, then enable start-stop after gaining proficiency. Especially when reversing, it's recommended to turn off start-stop as the power steering might feel heavier. Here's how I teach students: when needing prolonged parking, press the brake firmly to activate both functions; when maneuvering, press lightly to engage only auto hold. Remember this rhyme: 'Heavy press - both on, Light press - just brake'.
