Can I continue driving with a tire pressure of 175?

A tire pressure of 175 kPa is not safe for driving. According to the international standard GBT2978-2008, the recommended tire pressure is generally 240-250 kPa for standard tires and 280-390 kPa for reinforced tires. The maximum tire pressure should not exceed 350 kPa. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Heavier steering wheel and increased tendency for the vehicle to veer, which compromises driving safety; Excessive movement of tire components, causing abnormal heat due to over-compression; Reduced functionality of the cord and rubber, leading to delamination or cord breakage, and excessive friction with the rim, resulting in damage to the bead area and abnormal wear; Exponentially increased friction between the tire and the ground, causing a sharp rise in tire temperature, softening of the tire, and a rapid decrease in strength. High-speed driving under these conditions may lead to a blowout; Increased deformation of the tire body, making the tire sidewalls prone to cracks, and generating flexing movements that lead to excessive heat, accelerating rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders. Solutions for insufficient tire pressure: If no damage is visible, simply inflate the tire to the normal pressure and reset the tire pressure monitoring system; If a puncture is found during inspection, drive to a tire repair shop promptly for a patch, then reinflate the tire; If the tire pressure warning reappears some time after inflation without any visible puncture, it may be due to air leakage caused by a deformed rim. It is recommended to inspect the rim and replace it if necessary.

Why Do Anti-Slip Pad Marks Disappear Automatically?

It is normal for anti-slip pad marks to disappear automatically. Mark disappearance: If the anti-slip pad has been used for a long time without being moved, the dashboard underneath may develop a color difference with the surrounding area. However, this color difference will gradually fade over time. If the issue is related to the quality of the anti-slip pad, there may be adhesive residue that will not disappear without cleaning. Function:

How often should the air filter of Volkswagen Polo be replaced?

According to the vehicle's maintenance manual, the air filter of Volkswagen Polo should generally be replaced every 10,000 to 20,000 kilometers or every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The position of the car's air filter element is determined by the intake form and the structure of the engine. It is usually located in the air filter on the engine intake pipe. There are two types of air filters in cars: dry and wet. The dry type is made of paper or organic materials, while the wet type is made of metal wire mesh. Function of the air filter: It filters out particulate impurities in the air, ensuring that sufficient clean air enters the cylinder and preventing floating dust in the air from being sucked into the engine, which accelerates the wear of the piston group and the cylinder. Air filter: Also known as air filter cartridge, air cleaner, or style. It is a device that removes particulate impurities from the air. When the engine is running, it needs to suck in a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder can cause severe cylinder scoring, which is particularly serious in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand in the air, ensuring that sufficient and clean air enters the cylinder. A dirty air cleaner: Using a dirty air cleaner while driving will cause insufficient engine intake, incomplete fuel combustion, leading to unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car must keep the air cleaner clean. The car air cleaner is a device that removes particulate impurities from the air, consisting of one or several air filter components. Its main function is to filter out harmful impurities in the air that is about to enter the cylinder, to reduce early wear of the cylinder, piston, piston ring, valve, and valve seat. Therefore, before the air enters the cylinder, it must first pass through the fine filtration of the air cleaner. A dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When checking the air cleaner, if it is found to have little dust and is lightly clogged, it can be cleaned with high-pressure air from the inside out and continue to be used. A severely dirty air cleaner should be replaced in time. Volkswagen Polo air filter cleaning method: Preferably use an air gun to blow, or you can also use a household hair dryer. Due to the structure of the filter, blow from the intake side first, then from the inside out, and finally gently tap the surface of the air filter. Never use water to clean it, otherwise, you will have to replace it.

Why does the battery light come on while driving?

There are two main reasons why the battery light comes on while driving: 1. Battery failure, such as depleted power or battery malfunction. The solution is to use a multimeter to test the battery voltage. If the voltage is low, recharge it to restore power. If the battery is faulty, replace it. 2. Loose or oxidized battery terminals causing poor contact can also trigger the battery light. The solution is to clean and tighten the battery connections. A car battery, also known as a storage battery, is a type of battery that converts chemical energy into electrical energy. The commonly referred to car battery is a lead-acid battery, which is mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte.

Where is the Cabin Air Filter Located in a Corolla?

Corolla's cabin air filter is located behind the glove box. To access it, pull out the connecting rod on the right side and firmly push the glove box downward to reveal the filter. Commonly referred to as a pollen filter, the cabin air filter functions to purify air entering the vehicle interior by removing impurities such as fine particulate matter, pollen, bacteria, industrial exhaust fumes, and dust. The Corolla represents Toyota COROLLA's tenth-generation linear upgrade, with body dimensions of 4635mm (length) × 1780mm (width) × 1455mm (height) and a wheelbase of 2700mm.

Why is the Mazda CX-4's fuel consumption high?

Mazda CX-4's high fuel consumption reasons are introduced as follows: 1. Insufficient tire pressure: Insufficient tire pressure will increase the contact area between the tires and the ground, increasing friction, which means higher driving resistance and increased fuel consumption. 2. Ignition coil failure: Problems with the ignition coil. If the ignition coil has issues, it may cause some cylinders to stop working, reducing power. However, fuel injection continues as usual without any effect, leading to increased fuel consumption. 3. Engine carbon deposits: Long-term operation of the vehicle inevitably leads to carbon deposits and sludge from fuel combustion. If these deposits and sludge are not cleaned in time, they will cause an increase in the car's fuel consumption.
