Cadillac CT5's handbrake is automatic. The latest 2021 Cadillac CT5 has four models on sale, all equipped with automatic transmission. Specifically, it's a 10-speed automatic manual transmission, which offers excellent shifting smoothness and coherence, providing a very high driving comfort. Starting operation: The starting operation for automatic transmission models is very simple. First, after entering the car, adjust the seat and mirrors, fasten the seatbelt, press the brake to start the car, shift into drive gear, release the handbrake completely, turn on the left turn signal, observe the surroundings for safety, slowly lift the brake, and then gently press the accelerator to start successfully. Pay attention to the force used on the brake and accelerator. Gear usage notes: The gear can only be shifted into reverse when the car is completely stationary. When parking or starting on a slope, pay attention to the coordination between the brake and accelerator to prevent rolling. Avoid using high gears at low speeds or low gears at high speeds.

I drive a CT5, and the electronic parking brake is super practical! It's neither a traditional mechanical handbrake nor a foot brake, but a button hidden next to the gear lever. When you shift to D and press the gas to start, the parking brake releases automatically; when you park, shift to P, and turn off the engine, that 'buzz' sound means the electronic parking brake has auto-locked. If you're waiting temporarily, you can manually press the P button to lock it. Once, I tested it on a steep slope in the garage—stepping on the brake, shifting to N, and unbuckling the seatbelt, and it immediately auto-locked without even a chance to roll. For automatic transmission models, this electronic parking brake is way more effortless than a hand lever.

Electronic parking brakes (EPB) have become incredibly common in automatic transmission vehicles. The CT5's EPB is integrated into the left side of the gearshift area, marked with a small button featuring the electronic handbrake icon. Its parking logic is quite intelligent: when parked and shifted into 'P' gear, it automatically locks; a light tap on the throttle in 'D' gear releases it automatically. It's also compatible with manual mode—holding the button down lets you hear the motor engage. Some drivers even prefer using the auto-hold feature with start-stop for long trips, eliminating the need to press the brake pedal at traffic lights. The biggest difference from traditional handbrakes? The rear calipers are motor-driven, completely doing away with the classic 'click-clack' handbrake sound.

The handbrake is indeed not directly related to automatic transmissions! The electronic parking brake standard across the entire CT5 lineup belongs to the intelligent parking system. During last week's test drive at the dealership, I discovered that when stopping on a slope steeper than 5%, firmly pressing the brake activates AutoHold automatic parking, and a green P icon illuminates on the dashboard. A light tap on the accelerator automatically releases it when starting again. In emergency situations, pulling and holding the button while driving can also provide brake assist. I remember the salesperson mentioning there's an emergency release pull ring on the side of the trunk in case the battery runs out of power.

After getting used to the CT5, I really can't go back to manual handbrakes. Its electronic parking button is integrated next to the driving mode knob, eliminating the need to shift to P at traffic lights. The AutoHold automatic locking is 0.3 seconds faster than traditional handbrakes. Once tested in an underground garage slope: unbuckling the seatbelt and opening the door instantly triggered the automatic handbrake. The principle is that the BCM module receives signals from the gear, throttle, and seatbelt to control the electric motor brake. If upgraded to the premium version, activating the turn signal when entering a curve will also trigger the automatic parking release.
