Do I not need to press the handbrake after pressing P in a Mercedes?

Mercedes vehicles require the use of the electronic handbrake when shifting into P gear. There is a significant difference between the P gear and the electronic handbrake. The electronic handbrake, also known as the parking brake, prevents the vehicle from rolling by applying the brakes. The P gear, on the other hand, is a locking mechanism of the transmission. Prolonged use of P gear without engaging the electronic handbrake can affect the transmission. Below is an introduction to Mercedes-Benz vehicles: 1. Classification: The models produced domestically by Mercedes-Benz include the A-Class, C-Class, E-Class, GLA, GLB, GLC, and others. 2. Powertrain: The C-Class is a mid-size sedan, with domestic versions available in both standard and long wheelbase variants. The domestic C-Class is equipped with three engines: a low-power 1.5-liter turbocharged engine, a high-power 1.5-liter turbocharged engine, and a 2.0-liter turbocharged engine. All three engines are paired with a 9-speed automatic transmission (9AT).

I've been driving Mercedes-Benz cars for decades, and this is quite a common issue. Pressing the P gear only locks the transmission, mainly relying on internal gear stops to prevent the vehicle from rolling forward or backward, but it's not a foolproof guarantee, especially on slopes or uneven roads, where there's still a slight risk of wheel movement. Therefore, I recommend everyone develop the habit of pressing the handbrake button after parking. Mercedes' electronic handbrake system responds quickly—just one press activates it, providing double protection for peace of mind. Safe driving should never be taken lightly; this habit not only prevents rolling but also reduces transmission wear and extends your beloved car's lifespan. The specific operation is simple: shift to P gear, keep your foot on the brake, and lightly press the handbrake button. If your new car has an automatic function, it will engage the handbrake when parked, but manually confirming it never hurts.
