Why did Corolla change its name from Huaguan?

What does it mean when the vehicle's engine light is on?

The reasons for the vehicle's engine light being on are: 1. Sensor damage, poor contact, or signal interruption; 2. Poor engine maintenance; 3. Poor quality fuel and engine oil; 4. Incomplete combustion of the air-fuel mixture; 5. Faulty spark plugs or ignition coils; 6. Fuel pump failure or clogged fuel lines; 7. Clogged air filter. The solutions for the vehicle's engine light being on are: 1. Use fuel additives to clean the entire fuel system; 2. After cleaning the engine, use higher-grade gasoline; 3. Use high-quality fuel additives to improve the cleanliness level of the fuel; 4. Replace the catalytic converter.

Do You Need to Use Turn Signals When Starting on a Slope?

You do not need to use turn signals when starting on a slope. Here are the steps for starting on a slope: 1. Adjust the seat, press the clutch and brake, release the handbrake, slowly release the clutch until you feel the car vibrate, then gradually release the brake until the car starts moving uphill. 2. Align the protruding line on the car hood with the cement seam on the ground, and stop when your shoulder aligns with the designated line, then press the brake. 3. When reaching the designated stopping and starting area on the slope, slowly climb up, feel the car vibrate, then gradually release the brake until the car continues moving forward. Stop when the light turns red by pressing the clutch and brake, and shift to neutral. 4. When there are 4-5 seconds left before the light turns green, do not touch the clutch, lightly press the brake, and let the car naturally roll backward. Check the left rearview mirror, and when the car aligns with the cement seam, slowly reverse and stop, then pull the handbrake. Here are situations where you need to use turn signals: 1. When turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, you should turn on the left turn signal in advance. 2. When turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside, you should turn on the right turn signal in advance. 3. When entering a highway from an on-ramp, you should turn on the left turn signal and merge into the lane without obstructing the normal flow of traffic on the highway.

Can You Still Drive When the Oil Life is 0?

When the oil life reaches 0, it is not recommended to continue driving. Here is some extended information about oil life: 1. The vehicle's computer alerts you about oil life based on preset mileage. 2. If the oil life displays as 0, check whether it is due to a data error caused by not resetting after an oil change or prolonged disuse of the oil. 3. Engine oil has a shelf life and cannot be used indefinitely. The shelf life of oil depends on its condition. Unopened engine oil can last up to five years; leftover oil after a car service, being opened, has a shortened shelf life of about one year; oil already poured into the engine has the shortest shelf life, approximately six months. 4. While checking the car's oil, you can use an oil inspection filter paper to test if the oil has deteriorated. By dripping oil onto the filter paper, three important ring-shaped areas can be observed: the deposit ring, the diffusion ring, and the outer oil ring, which indicate the oil's contamination level, the dispersing ability of additives against contaminants, and the oil's oxidation level.

What are the causes of brake noise after vehicle startup?

Vehicle startup after the brake noise causes are: 1, too slow to release the brake caused; 2, the new replacement of the brake pads running-in is not in place; 3, sand particles into the middle of the brake pads and brake discs; 4, the brake disc fixing screws are lost or damaged; 5, the brake system failure. The brake maintenance methods are: 1, high temperature protection, to prevent the brake system corrosion, to prevent the brake pads due to high temperature surface bite, to eliminate the brake pads scream; 2, regular replacement of brake oil; 3, clean the brake discs, brake drums and any parts of the oil stains, dirt and friction dust, to maintain the brake disc heat dissipation good; 4, regular inspection of the thickness of the brake pads or brake shoes.

What Causes the Brake Pedal to Be Hard to Press and the Car Unable to Start?

Here are the reasons why the brake pedal is hard to press and the car cannot start: 1. Vacuum booster pump leakage: If the car's vacuum booster pump leaks or malfunctions, the force required to press the brake pedal increases because the brake booster is not functioning properly. If it fails, the brake loses its power assistance, making it difficult to press. 2. Normal phenomenon: The inability to press the brake pedal after the engine is turned off is related to the brake booster pump. The brake booster pump only continuously generates vacuum when the engine is running. When the engine is off, it relies on the remaining vacuum assistance, but this will restore once the engine starts, and it is not a malfunction. Additional info: In driving, to prevent unexpected situations like sudden movement or rolling when starting the car, automatic transmission models are designed to require pressing the brake pedal to start. If the brake pedal is not pressed, the car will not start successfully. Moreover, the gear must be in P (Park) or N (Neutral) when starting an automatic transmission car. If started in N without the handbrake engaged, the car may roll. Therefore, the "press brake to start" design is entirely for safety considerations.

Is Brake Maintenance Necessary?

Brake maintenance is necessary. Only by timely servicing the components of the brake system and cleaning and lubricating the safety parts can the accuracy and safety of the brakes be ensured. Below are the phenomena that may occur if the brake system is not maintained for a long time: 1. Abnormal noise: The dust from normal wear of the brake pads accumulates near the brake calipers, and if not cleaned for a long time, it can cause abnormal noise; the sound-damping and vibration-damping plates of the brake pads, if not cleaned and lubricated for a long time, can also cause brake noise. 2. Abnormal wear: When driving on gravel roads, some particles may splash between the brake pads and brake discs, causing noise or abnormal wear. 3. Brake deviation: If the dust cover of the sliding shaft of the caliper is damaged, driving through water or mud puddles can cause the caliper shaft to rust and seize, the caliper to not return to position, reduced braking force, and brake deviation.
