BYD Surui cannot detect the key with one-key start for the following reasons: Insufficient key battery power: For example, the key battery has not been replaced for a long time. Solution: Replace the battery. Here is a simple way to check: If the red indicator light on the remote key flashes when you press the button, it means the key battery is normal. Key malfunction: For example, the control unit of the key is damaged. Solution: Get a new key. Signal interference nearby: You can first use the mechanical key to drive the car to another location and try again. If it works, it indicates that the remote key failure is caused by severe signal interference.

Is the first maintenance required within three months for a new car?

The first maintenance is normally scheduled at 6 months or after driving 5,000 kilometers, whichever comes first. Below is a relevant introduction to the first maintenance of a car: 1. Engine system: Replace the engine oil and oil filter. Check if all lubricating fluids in the engine compartment are sufficient and if related components are loose. 2. Lighting system: Check if the lighting system is functioning properly. 3. Vehicle tires: Inspect for excessive wear on the tires. 4. Shock absorbers: Check for oil leaks in the shock absorbers. 5. Vehicle chassis: Examine the chassis for any scratches, damage, looseness, or rust issues.

How to Deal with High Fuel Consumption?

Here are the methods to address high fuel consumption in cars: 1. Replace tires promptly: When tires are severely worn, the tread becomes smooth, reducing friction. This makes the car more prone to slipping while driving, which increases fuel consumption. Car owners should be aware of the service life or recommended mileage for their tires and replace them promptly when noticeable slipping occurs. 2. Get timely inspections at a 4S shop: If the bearings or braking system malfunction, the tires may not work properly, leading to increased fuel consumption. Issues with bearings and brakes often manifest through symptoms such as unusual noises from the tires. In such cases, car owners should consider these possibilities and promptly visit a 4S shop for inspection.

Can an Automatic Transmission Be Parked in Neutral?

If waiting at a red light or temporarily stopping for just two or three minutes, you can shift into neutral, but you must keep your foot on the brake, and it's best to engage the handbrake. If you park the car and need to leave for an extended period, it is not recommended to leave it in neutral; it's better to shift into P (Park). Below is additional information: 1. The difference between P (Park) and neutral: At a red light, you can use P (Park) or neutral (N). If the car won't roll, you can use neutral. If parking for more than an hour, shift into P (Park). There is a difference between P (Park) and neutral. Neutral means the car is stationary, with the gear lever not engaged in any forward or reverse gear, and the transmission is completely disengaged from the drive wheels. In this state, the car has no braking force and relies on the handbrake for braking. Traditional handbrakes use a steel cable to pull a claw mechanism that restrains the rear wheels. 2. Parking in P (Park): The P (Park) position involves an internal pawl in the transmission, somewhat like a latch, to prevent the car from moving, which is different from neutral. Many modern cars won't allow the key to be removed or the car to be locked unless shifted into P (Park). Of course, if you prefer not to use P (Park) and would rather park in neutral with the handbrake engaged, as long as you can remove the key and lock the car, that is also acceptable.

What is the 0-100 km/h acceleration time of the Ghost?

The Ghost is equipped with a 6.6T engine, available in two power output versions, with 0-100 km/h acceleration times of 4.9 seconds and 4.8 seconds respectively. Here is an introduction to the Ghost: 1. Exterior: The new car retains the design of the standard-wheelbase Ghost model, featuring the iconic Pantheon grille at the front with a vertical waterfall-style mesh, giving it a very imposing look. The headlight clusters on both sides adopt a futuristic new design, with C-shaped LED daytime running lights extending from the eyebrows, enhancing the car's technological appeal. The lower front fascia features a youthful bumper design with square contours on both sides, adorned with chrome trim. At the rear, the design is clean and simple, with circular taillights featuring intricate internal LED layouts and a prominent bumper. The rear also features hidden exhaust pipes, which is the most significant difference from the standard-wheelbase version. 2. Powertrain: The new car continues to be powered by a 6.75L twin-turbocharged V12 engine, delivering a maximum power output of 571 horsepower and a peak torque of 850 Nm. It is paired with an 8-speed automatic transmission from ZF and an all-wheel-drive system, achieving a 0-100 km/h acceleration time of just 4.8 seconds and a top speed of 249 km/h.

What Causes the Noise After Replacing Brake Pads?

There are many types of brake pads available now. It is recommended to replace them with original ones or materials with similar friction coefficients. Sometimes, brake pads that work well on one vehicle may not be suitable for another, which is due to the mismatch between the brake pads and the brake discs. The reasons for noise after replacing brake pads are as follows: 1. Excessive friction coefficient: This means the brake pads are too hard, causing them to act like they are cutting into the brake discs, resulting in a clunking sound or other noises, depending on the hardness match and braking force. 2. The stiffness of the brake pads is close to that of the brake discs: This can easily cause resonance, and the noise is generated by vibration, but it is not a clunking sound. 3. There are granular hard particles on the surface of the brake pads: These can cause a screeching sound when scraping against the brake discs.

Why does the car vibrate at idle speed?

Car idle vibration is caused by engine carbon deposits, aging or carbon buildup in spark plugs, dirty engine throttle, poor fuel flow, or ignition system failure. More detailed information is as follows: 1. Engine carbon deposits: Engine carbon deposits result from various reasons, but most are due to poor driving habits of the owner. Components such as ignition coils, spark plugs, and high-voltage wires have their service life. Once problems arise, they can lead to poor ignition system performance, resulting in idle vibration. 2. Spark plug carbon deposits: Among these, spark plug carbon deposits are particularly severe. This requires the owner to check if there is carbon buildup in the spark plugs. If there is excessive carbon buildup, replace them regularly. Ignition system failures should be addressed promptly, as severe cases can cause the engine to fail to start or even suddenly stall during driving, leading to unnecessary trouble.
