Conventional roads: 50 to 100 meters away, Expressways: 150 meters away. Introduction to warning triangles: The accurate name for the triangular warning sign is the motor vehicle warning triangle. The automotive warning triangle is a passive reflector made of plastic reflective material. Functions: When a driver encounters an unexpected breakdown requiring parking for repairs or an accident on the road, upon noticing a warning triangle ahead, they need to go through a process of discovery, clearly seeing the warning signal ahead, taking measures to brake, slow down, and yield. Utilizing the reflective properties of the warning triangle can alert other vehicles to take evasive action, thereby preventing secondary accidents.

What are the solutions for a clicking sound when shifting gears?

The solutions for a clicking sound when shifting gears are: 1. Check if the transmission oil is sufficient, and add more if the oil level is too low; 2. Fully depress the clutch every time you shift gears. If the issue does not improve significantly, check the clutch clearance, free travel, and other parameters; 3. Replace the gears and synchronizer; 4. Replace the bearings and thrust washers. The reasons for a clicking sound when shifting gears are: 1. Incomplete clutch disengagement; 2. Severe wear of gears or synchronizer in the transmission, leading to excessive clearance; 3. Excessive clearance between the bearing and the spline on the shaft; 4. Severe wear of the shift fork shaft.
