For front-wheel-drive vehicles, the reasons for a rear wheel not turning include: 1. The brake caliper not retracting or a blocked hydraulic line. 2. The brake pads not separating or foreign objects embedded behind the brake pads. 3. A seized wheel hub bearing. For rear-wheel-drive vehicles, the reasons for a rear wheel not turning involve not only checking the braking system but also inspecting the rear axle's main reducer and differential planetary gears. Below is relevant information about car tires: 1. Replace tires when tread depth is below 1.6mm: According to national standards, the wear limit for tread depth on passenger car radial tires is 1.6mm. On the sidewall of the tire, there is a wear indicator signal mark every 30 degrees. You can compare it with a key you carry. If the groove depth is below 1.6mm, the tire should be replaced. 2. Neither underinflation nor overinflation is advisable: Incorrect tire pressure can lead to cost losses and hazards. Underinflation reduces the tire's durability, increases rolling resistance, and lowers fuel economy. Overinflation decreases traction performance, causes irregular wear, especially on the drive axle.

I've encountered the issue of the right rear wheel not turning several times. With years of driving experience, I know it can be caused by various reasons. The most common is a stuck brake system, such as faulty brake pads or a caliper, which locks the wheel completely. It could also be due to worn rear wheel bearings, making rotation extremely difficult. For rear-wheel-drive vehicles, problems with the differential or drive shaft can also affect wheel rotation. Additionally, a flat tire or rusted wheel hub might jam the wheel. First, check around the wheel for any foreign objects blocking it, then try pushing the car to see if it moves. If the problem persists, don't force it to drive—it's very dangerous. Regular car washing to prevent rust can help reduce such failures.

What to Do When Encountering a Scrape in a Parking Lot?

Solutions for encountering a scrape in a parking lot: 1. If the car is in a free parking lot, you can file a claim with the insurance company or seek compensation from the responsible party. 2. If it's in a paid parking lot, you can seek compensation from the parking lot management or the responsible party. 3. If the car is parked in a free parking lot and not illegally parked, you can report it to your insurance company for compensation. If the responsible vehicle cannot be found, the insurance company typically applies a deductible rate of 10-30%, usually around 30%. Legal basis: According to Article 8 of the "Special Vehicle Insurance Clause Regulations," if the vehicle damage should be compensated by a third party but the third party cannot be found, the insurance company has the right to deduct a 30% deductible rate, thus compensating the car owner for only 70% of the loss.

What does a key symbol displayed on the car dashboard mean?

When a key symbol appears on the car dashboard, it indicates that the vehicle's anti-theft system has been triggered. After the anti-theft system light comes on, the following phenomena should be noted: 1. If the anti-theft system light is on and the car won't start, it means the vehicle cannot be activated. The anti-theft indicator light includes both the factory-installed anti-theft indicator and any aftermarket anti-theft system indicators. The anti-theft indicator has armed and disarmed states, with different flashing frequencies in these two states. 2. It's important to note that if the engine anti-theft light flashes once every 1 to 2 seconds, this is normal. It indicates that the vehicle's engine has entered the anti-theft state and the engine immobilizer is functioning properly. This is a normal condition that doesn't require the owner to deactivate it, and the power consumption is negligible, posing no issues for the battery.

How to Defog When Driving in Rainy Summer Days?

The usual method is to turn on the car's fan and cooling switch, so that the cold air blows onto the glass, quickly dispersing the fog with fast and direct results. Here are more methods for defogging: 1. Use specialized defogging products. Many markets and auto parts stores have stalls selling dedicated defogging and anti-fog products, such as defogging sprays or fog towels. Spray this type of defogging agent onto the inner surface of the car glass and wipe it clean. While removing dirt from the glass, it also forms a thin transparent protective film that prevents water vapor from condensing into fog on the glass. One application can prevent fog for about ten days to half a month. 2. Open windows for convection: If the fog is not heavy, you can open a small gap in the side windows to allow air convection inside the car. The temperature inside the car will gradually approach the outside temperature, and the fog will disperse. 3. Detergent-based anti-fogging: Mix dishwashing liquid with water in a ratio of about 1:10, then use absorbent cotton or a clean, soft cloth to apply it to the inside of the front and rear windshields.

How to turn on the high beam on a CRV?

The low beam is generally indicated by a green symbol with non-parallel light lines; the high beam is usually indicated by a blue symbol with parallel light lines. The turn signal lever on the left side of the steering wheel has two rows—the first rotatable one controls the headlights. After turning on the headlights, press it downward to activate the high beam.

How to adjust the valves of the P13 engine?

Rotate the crankshaft to determine the engine's firing order. Rotate the crankshaft to the top dead center of the first cylinder's compression stroke. When the first cylinder is at the top dead center of the compression stroke, both valves are closed. Adjust the intake and exhaust valves of the first cylinder. Rotate the crankshaft 360 degrees to the top dead center of the first cylinder's exhaust stroke, then adjust all remaining valves.
