What Causes Steering Wheel Vibration When Driving at 120 km/h?

What are the steps to charge a car battery?

The steps to charge a car battery are: 1. Ensure the engine is turned off and remove the battery from the vehicle; 2. Place the battery in a well-ventilated, cool, and open area, and open the vent caps on the battery; 3. Wear goggles and rubber gloves, then attach the charger's red clamp to the battery's positive terminal marked with a plus sign, and the black clamp to the negative terminal marked with a minus sign; 4. Select the slow charging mode, set the gear to 2, and choose a 12V power source; 5. Plug in the charger, turn on the power, and start the charging process. Precautions for charging a car battery: 1. In cold weather, check if the electrolyte is frozen before charging; 2. Check the electrolyte level before charging; 3. Measure the electrolyte density and voltage approximately every hour during charging and monitor its temperature; 4. Ensure the charging area is well-ventilated and strictly prohibit open flames; 5. Stop charging if unattended.

What type of tires does the Toyota Vios use?

Toyota Vios tire specifications are divided into 175/65R14 for low-end configurations and 180/60R15 for mid-to-high-end configurations. The Toyota Vios predominantly uses Bridgestone tires, with some models equipped with Dunlop or Hankook tires. Below is an introduction to the Toyota Vios: Model: The Vios is an entry-level family car specifically designed and developed by Toyota for the Asian market. Based on the NBC platform, the Vios, with its extended wheelbase, nearly reaches the level of a compact sedan within the small car platform. Engine: The Vios is equipped with a domestically produced 16-valve 5A-FE engine. This engine is almost identical to the commonly used 8A engine in the domestic market, except for an increase in piston stroke, which raises the displacement from 1.3 liters to 1.5 liters. Correspondingly, the maximum power output also increases to 68kw.

Can I Replace Just One Tire on My Car?

When replacing tires, it is generally not advisable to replace just one; instead, you should replace a symmetrical pair of tires. The reasons are as follows: 1. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance, which greatly determine the safety of the vehicle. 2. If the old tire is relatively new, it is recommended to replace it with the same model of tire. This is because differences in tread depth can affect the safety of the car during high-speed driving and in rainy or snowy conditions. When the tread pattern of the new tire differs significantly from that of the old tire, it can lead to inconsistent grip, causing the vehicle to pull to one side. Therefore, it is advisable to replace both tires on the same axle. 3. The new tires should preferably be installed on the drive wheels, and after replacement, a wheel balance should be performed. The replaced tires can be used as spare tires.

Does Car Air Conditioning Consume a Lot of Fuel?

Car air conditioning accounts for about 20% of the engine's power, so using the air conditioning consumes a portion of the engine's power, leading to an increase in fuel consumption. The specific increase in fuel consumption is related to the car's displacement and speed. Here is more information about the fuel consumption of car air conditioning: 1. After turning on the air conditioning, the vehicle's fuel consumption will significantly increase, mainly due to the operation of the compressor. The compressor has a relatively high power, which increases the engine's load, naturally leading to higher fuel consumption. 2. The higher the temperature and humidity, the greater the fuel consumption caused by the car air conditioning. When the temperature exceeds 20 degrees Celsius, the increase in fuel consumption varies between approximately 10% and 20% depending on the temperature and humidity. If the temperature reaches extreme levels around 40 degrees Celsius, combined with extreme humidity, the fuel consumption can increase by up to about 30%.

What Causes Water Leakage Under the Car?

Water dripping from the underside of the car onto the ground is a normal phenomenon. There are several reasons for this: 1. The car's air conditioning system is equipped with an evaporator inside the dashboard. When the air conditioning is turned on (A/C button ON), the surface temperature of the evaporator becomes very low, causing moisture from the hot air inside the car to condense on the heat-absorbing fins of the evaporator. The condensed water is then collected by the plastic casing of the evaporator and drained out of the car through a pipe. If the car is parked for a while, you might notice a puddle of clean, colorless, and transparent water, which is not a cause for concern as the engine coolant is usually antifreeze (green, red, or blue). 2. The compressor located in the engine compartment (low-pressure area) can also condense moisture from the air, causing water to drip onto the ground (sometimes in larger quantities than the evaporator's drainage). 3. If the low-pressure pipes are not wrapped with insulating foam, the surface of the pipes can easily condense moisture from the air, and water droplets often accumulate and drip from the lowest point of the pipes.

Can You Turn Right on a Straight Red Light?

Whether you can turn right when the straight light is red depends on the specific situation. With an arrow red light, if both the straight red light and the right-turn arrow red light are illuminated simultaneously, right turns are prohibited. With a circular red light, if there is a "No Right Turn on Red" sign at the intersection, right turns are prohibited. Additionally, if there is a "No Right Turn" sign at the intersection, right turns are not allowed. Otherwise, when the red light is on, right-turning vehicles may proceed provided they do not obstruct the passage of other vehicles or pedestrians. More details are as follows: I. Non-motorized vehicle traffic lights: These consist of a set of circular units with bicycle symbols in red, yellow, and green, guiding non-motorized vehicles. II. Relevant provisions of Article 10, Chapter 2 of the "Regulations on Road Traffic Safety of the People's Republic of China": 1. Traffic light signals: (1) When the green light is on, vehicles and pedestrians are permitted to proceed, but turning vehicles must not obstruct straight-moving vehicles or pedestrians; (2) When the yellow light is on, vehicles and pedestrians are generally not allowed to proceed, except for vehicles that have already crossed the stop line and pedestrians already in the crosswalk, who may continue; (3) When the red light is on, vehicles and pedestrians are not permitted to proceed; (4) When the green arrow light is on, vehicles are allowed to proceed in the direction indicated by the arrow; (5) When the yellow light flashes, vehicles and pedestrians may proceed under the principle of ensuring safety. Right-turning vehicles and straight-moving vehicles at a T-intersection without a crosswalk on the right may proceed under conditions (2) and (3) above, provided they do not obstruct other vehicles or pedestrians. The first two provisions also apply to people walking in queues or herding or riding livestock. Thus, in the absence of specific traffic instructions (such as traffic signs or police directions), motor vehicles may turn right on a red light without violating traffic rules.
