When shifting gears in an automatic transmission, you must press the brake. If there is an issue with the brake, the transmission will not be able to shift gears. The emergency switch is located next to the gear lever. Press the brake and use a flat-head screwdriver or a small metal rod to firmly press down on the emergency switch to enable gear shifting. Promptly go to a repair facility for inspection and repair, focusing on the shift solenoid valve, transmission synchronizer, gears, and other components.

What Causes the Squeaking Noise When Wipers Move on the Windshield?

The wiper is a cleaning tool on a car that ensures the cleanliness of the windshield and maintains the driver's clear visibility. 1. Debris between the wiper and the windshield: When the car is stationary, debris such as leaves and dust may accumulate on the windshield. If the wiper is activated without cleaning these debris, it can cause squeaking noises and, in severe cases, even scratch the windshield. 2. Issues with the wiper blade: The wiper blade is made of rubber and will naturally age over time. Prolonged exposure to sunlight can cause the blade to harden and deteriorate. 3. Misalignment of the wiper: The wiper has a fixed position to properly cover the windshield. However, over time, the wiper may shift out of place. 4. Fault in the wiper linkage mechanism: The linkage mechanism of the wiper is complex, and malfunctions in components such as the motor or intermittent relay can cause the wiper to move too fast or too slow, leading to squeaking noises.

What Can Be Used as a Substitute for Battery Fluid?

Battery fluid can be replaced with distilled water. Lead-acid batteries are chemical reaction devices composed of positive and negative plates, separators, and a solution containing sulfuric acid, used for storing and discharging electricity. In cases where the battery fluid is low, you can add battery replenishment fluid or distilled water. Tap water and purified water contain certain minerals and should not be used as substitutes for battery fluid. Here is some information about battery fluid: 1. Battery fluid, also known as electrolyte, is a dilute sulfuric acid made by mixing distilled water with sulfuric acid. It is used to react with the plates in the battery for charging and discharging. 2. Battery fluid is prepared by mixing specialized sulfuric acid and distilled water in a certain ratio, with a density generally ranging from 1.24 to 1.30 grams per cubic centimeter.

How Many Kilometers Can a Compact Spare Tire Run?

A compact spare tire should not exceed a maximum speed of 80 km/h and a driving distance of no more than 100 kilometers. A compact spare tire refers to a spare tire that is slightly smaller in diameter and narrower in width compared to the regular tires. Compact spare tires have different speed ratings and load indexes from the vehicle's four normal tires and cannot be used as a replacement; they are only for temporary use. Below is relevant information about compact spare tires: 1. Drive within the speed limit when using a compact spare tire: Since compact spare tires differ in specifications from the original tires, they usually have a speed limit marking, typically 80 km/h. After installing the spare tire, the driver must adhere to the speed limit for safety. If driving on a highway, choose the rightmost slow lane and turn on the hazard warning lights. 2. The spare tire should be installed on the front axle: Regardless of the vehicle's drive axle, tires with higher speed ratings should be installed on the rear axle to prevent potential oversteering (commonly known as "fishtailing"). Therefore, the spare tire with a lower speed rating should be installed on the front axle. 3. Compact spare tires should not be used for long periods: Prolonged use of a compact spare tire can significantly affect the vehicle's braking performance and handling due to its substantial differences from the original tires, compromising driving safety.
