Should You Shift Gear or Release the Handbrake First Before Driving?

Before driving, you should shift gear first and then release the handbrake. The main reason is that the road surface may not be completely flat, and there could be issues with the vehicle's throttle or clutch. Shifting gear before releasing the handbrake helps prevent the car from rolling forward or backward, thereby avoiding potential hazards. For manual transmission vehicles on a downhill slope: 1. Generally, shift to 2nd gear for moderate slopes; 2. Shift to 3rd gear for slopes steeper than 30 degrees; 3. Shift to 4th or 5th gear when going up or down elevated roads. The handbrake is a crucial component of the vehicle's braking system, serving the following purposes: 1. When parking, pulling the handbrake keeps the car stationary and prevents it from rolling downhill; 2. Applying the handbrake while turning during driving can create a drifting effect; 3. In emergencies, the handbrake can be used as a brake.

How to Replace the Brake Light on a Lavida?

Lavida brake light replacement method is as follows: 1. First open the rear trunk. There is a white hand-twist screw on the back of the taillight. Unscrew the screw, then disconnect the plug, remove the old brake light, and install the new one. 2. The Lavida brake light is installed at the rear of the vehicle and is red in color to enhance the penetration of the light source. This ensures that vehicles behind can easily detect when the front vehicle is braking even in low visibility conditions, thereby helping to prevent rear-end collisions. 3. In addition to the brake lights installed at both ends of the rear, there is also a high-mounted brake light installed at the upper part of the rear. Some newer cars have a square or rectangular red brake light in the higher central position at the rear, which is the high-mounted brake light. It is generally positioned higher than the brake lights on both sides of the rear. The purpose of the high-mounted brake light is to alert vehicles behind, thus helping to avoid rear-end collisions.
