What is the function of the button on the gear shift of the Buick Excelle?

The shift button is equivalent to the clutch of a manual transmission. The following are specific details about the Excelle: 1. Body dimensions: Its body length, width, and height are 4609mm, 1798mm, and 1486mm respectively, with a wheelbase of 2640mm, a fuel tank capacity of 44 liters, and a body weight of 1285kg. 2. Powertrain configuration: The 2021 automatic light hybrid entry-level Excelle features a MacPherson independent front suspension and a multi-link independent rear suspension. It is equipped with a 1.3t turbocharged engine, delivering a maximum horsepower of 163ps, a maximum power of 120kw, and a maximum torque of 230nm, paired with a 6-speed automatic manual transmission.

When I used to drive a Buick Excelle, I paid special attention to that button on the shift lever. It's called the shift lock release button, mainly designed to prevent accidental gear shifts while driving. Every time you shift from P to R or D, you must press it to move the lever. Last time when my friend borrowed the car, he tried to force the lever without pressing it and thought the car was broken. Actually, this safety feature is quite thoughtful - especially preventing accidental shifts to Neutral during reversing. Also, if you can't remove the key after turning off the engine, pressing this button while stepping on the brake can unlock it. Just be careful not to let children play with it, as accidentally shifting gears could lead to dangerous rolling.

The button on the automatic gear lever of the Buick Excelle is called the gear shift lock, specifically designed to lock the transmission. When driving, I usually shift to N gear and pull the handbrake at red lights. To shift back to D gear when starting again, I need to press the button. This design prevents accidental gear shifts by mistakenly touching the lever while driving, especially when shifting from R gear to P gear, where you must press the button hard, or it won't move. Once, foam from car washing seeped into the button, causing it to stick, but it was fixed by spraying WD-40. It's recommended to regularly check the button's elasticity; if it sticks, it might affect gear shifting.

That silver button is actually a safety device. When shifting gears in the Excelle, you must press it to operate, such as when you want to shift into P after parking. When I first started driving, I often forgot to press the button and would get so anxious that I'd break out in a sweat. Later, I realized how important this design is. Without this lock function, it would be disastrous if you accidentally bumped the gear lever into reverse at a red light. Now, every time I start the car, I naturally press the button to shift gears, forming a habit that also protects the transmission. Special note: the button may become stiff in winter, and warming up the car in advance can help.

The shift lever button serves as part of the electronic anti-theft system. When driving my Buick Excelle, I noticed that pressing the button without stepping on the brake pedal is completely ineffective—this is actually a dual-protection mechanism. It primarily addresses two scenarios: first, preventing gear shifts when the key isn't powered on, and second, avoiding accidental reverse gear engagement while driving. Once when lending the car to a novice driver, they nearly shifted to R at 20 mph, but the button's lock mechanism prevented it. For optimal operation, press the center of the button with your thumb during gear changes; prolonged edge pressing may wear out the plastic components.

The round button on the Buick Excelle's gear shift lever is a mechanical gear lock. I remember it tends to soften in high summer temperatures, making it less responsive to press. Its core function is to establish shift safety logic: shifting to D requires brake pedal + button press, while shifting to R requires complete stop + button press. During the last maintenance, the technician mentioned this button has a lifespan of approximately 100,000 presses, and advised avoiding forceful poking with fingernails. A lesser-known fact: when the battery is completely dead, there's an emergency release hole hidden beneath this button where you can insert a key to unlock the gear.
