Should the Handbrake Be Engaged When Parking an Automatic Transmission Vehicle?
1 Answers
When parking an automatic transmission vehicle, it is advisable to engage the handbrake. Below is a detailed explanation of why the handbrake should be used when parking an automatic transmission vehicle: 1. When the automatic transmission is in P (Park) mode: The vehicle is designed to stay stationary on a slope within a certain angle, but it may not hold if the slope exceeds that angle. 2. When waiting at a red light in D (Drive) mode with the foot brake applied: The torque converter in the transmission will continue to operate, causing the transmission fluid temperature to rise and increasing fuel consumption. Additionally, the brake pump and vacuum booster remain engaged. It is best to shift to P mode and engage the handbrake, then shift back to D mode when the light turns green. 3. If you frequently wait at red lights in D mode with the foot brake applied: If the brake is not firmly pressed, it may lead to a rear-end collision.
