Car vibration when driving can be caused by the following reasons: 1. Low ignition energy: faults caused by carbon deposits on valves or intake manifolds, improper air-fuel mixture, failure of the coolant temperature sensor, or variations in cylinder performance; 2. Prolonged vehicle use: The ignition gap of spark plugs can easily widen, reducing ignition energy and affecting power performance, leading to car vibration. Additionally, aging ignition coils, aging high-voltage wires of spark plugs, or leakage can also decrease ignition energy. 3. Tire misalignment: Loss of tire dynamic balance effectiveness or detachment of balance weights. 4. Deformed or unbalanced drive shaft: Some vehicles that have experienced chassis collisions may exhibit similar issues.

Where is the turn signal switch located in the car?

The turn signal switch in the car is located below the left side of the steering wheel, featuring a lever. Pushing it downward activates the left turn signal, while pushing it upward activates the right turn signal. Returning it to the middle position turns it off. The turn signal is an essential indicator light that is activated when a motor vehicle is turning, alerting surrounding vehicles and pedestrians. The turn signal bulb uses a xenon tube, controlled by a microcontroller circuit, flashing alternately left and right without interruption. The turn signal is frequently used to clearly indicate the intended direction of the vehicle to others on the road.

Why Can't the Accord Rear Door Be Opened from Inside?

It cannot be opened because the child lock is engaged; simply disengage the child lock to open the door. Here is some information about the child lock: 1. The Honda Accord child lock, also known as the door lock child safety feature, is located on the rear door lock. When the rear door is opened, there is a small lever (safety mechanism) below the door lock. Move the lever toward the end with the child icon, then close the door. At this point, the door cannot be opened from the inside but can only be opened from the outside. 2. The purpose of the child lock is to prevent active and unaware children from opening the door while the car is moving, thereby avoiding danger. This means the door can only be opened from the outside by an adult after the car is parked. If the rear door of your car cannot be opened from the inside but can be opened from the outside, it is highly likely that the child lock is engaged. In this case, passengers in the rear seat may have accidentally activated the safety mechanism while getting in or out of the car. Simply reset it to resolve the issue. 3. Safety Reminder: For car owners without children, the child safety lock may seem like an unnecessary and often overlooked vehicle feature. However, for car owners with children, the child safety lock is a crucial safeguard for their child's life. Many parents often allow children to sit in the front seat, which is not equipped with a child safety lock, or fail to activate the rear seat safety lock, both of which pose serious safety risks to children. Therefore, parents should take proper in-car safety measures for their children, correctly using the safety lock to prevent accidents.

How to Switch Driving Modes in Volkswagen Tharu?

You can freely switch or set personalized driving modes according to driving needs and road conditions. Here is an introduction to the driving modes of the Tharu: 1. Standard Mode: The most commonly used mode for daily commuting, suitable for most road conditions, balancing power output and fuel economy. 2. Snow Mode: When the road is slippery or covered with snow, you can choose Snow Mode. This mode enhances the traction control system curve for straight-line driving, providing more traction during straight-line driving. It reduces the traction control system curve for cornering, offering more grip during turns. The flat acceleration characteristic curve provides earlier upshift points during acceleration. 3. Off-Road Mode: Primarily designed for terrains away from paved roads. The main features of this mode include: Active Driving Assist when descending hills, maintaining vehicle speed below 30km/h when descending slopes greater than 10%. Hill Start Assist, providing up to 2 seconds of assistance when starting on an uphill slope. ABS system logic adjustment, using the wedge effect on loose surfaces. The electronic differential lock provides a higher locking ratio at speeds below 80km/h; electronic stability control and traction control systems intervene later; flat acceleration characteristic curve; later upshift points during acceleration; no forced upshifts in manual mode. 4. Personalized Mode: Allows you to customize steering effort, drivetrain, air conditioning, and other settings to better suit your driving habits.

What Type of Engine Oil is Used for BMW 5 Series?

BMW 5 Series uses 5W30 engine oil. Below is additional information: Engine oil for BMW 5 Series: To maintain a balance of cleanliness, stability, oxidation resistance, and viscosity change resistance. The role of engine oil lubricant in BMW 5 Series is to lubricate and clean the engine. For a BMW 5 Series with a 2.0t engine, approximately 5.5 liters of oil is required. The amount of oil needed varies depending on the engine displacement, so add oil according to the actual condition of your vehicle. Engine oil for naturally aspirated engines: Naturally aspirated engines do not require high-performance oil; mineral oil or semi-synthetic oil can be used. If the budget allows, full synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more precise structure and operate in more complex conditions, requiring higher-quality oil with better fluidity, preferably full synthetic oil. Choosing engine oil: When selecting an engine oil brand, if you prioritize long-lasting performance, you can choose Mobil lubricants; if you focus on the cleaning performance of the oil, Shell lubricants can be used; if you need oil with strong film toughness, Castrol is recommended. For example, turbocharged engines are prone to carbon deposits during high-speed operation, so Shell oil with strong cleaning capabilities can be used.
