What kind of engine oil should be used for Verna car maintenance?

What is the difference between the ex-factory price and the manufacturer's suggested retail price?

The differences between the ex-factory price and the manufacturer's suggested retail price are as follows: 1. The manufacturer's suggested retail price (MSRP) refers to the official listed price. Generally, dealers will provide floating quotations based on this price when selling. Additionally, the MSRP serves as an important basis for calculating the purchase tax. It is a reference price for buyers and represents a non-binding quotation displayed by the seller, intended only for reference. 2. The ex-factory price is the actual price of the vehicle itself, simply put, the real price of the car excluding any additional fees. Typically, the ex-factory price does not include expenses such as purchase tax, license plate registration, insurance, etc. The purchase tax is a tax levied by tax authorities on the purchase of certain goods and properties within the scope of the tax system.

Is a wheel alignment necessary after rotating car tires?

Wheel alignment is required after tire rotation because there are specific angles and relative positions between the car tires, steering mechanism, and front/rear axles. After changing tires, these angles may become misaligned, potentially causing issues such as vehicle drifting, reduced steering precision, off-center steering wheel, or uneven tire wear. Timely wheel alignment is essential in such cases. Here's additional information: A four-wheel alignment helps maintain optimal angles between the tires and vehicle body, reduces wear between tires and steering components during driving, ensures firm contact between tires and the road surface, and enables stable straight-line driving. Wheel alignment is a maintenance procedure rather than a routine service—it's only necessary when problems occur, not as regular maintenance.

Do You Need to Turn on AC When Using Car Heater?

You do not need to turn on AC when using car heater. More information about AC is as follows: 1. The car AC switch, simply put, is the air conditioning cooling switch. AC stands for "Air-conditioning", meaning air conditioning device. This button controls the compressor's on/off function, and car air conditioning relies on compressor operation for cooling. 2. The main function of car AC switch is to adjust and control the temperature, humidity, air cleanliness and airflow inside the car compartment to optimal conditions. 3. When the car AC light is on, it indicates the air conditioning compressor is activated, increasing engine load and fuel consumption.

How long does it take for ETC to deduct money after exiting the highway?

ETC will deduct the fee immediately after passing the highway, and the latest deduction will be made within 5 working days. Precautions for using ETC: 1. Insufficient balance in the ETC stored-value card may result in being blacklisted by ETC, making it impossible to pass through national highways. It will take 24 hours after ETC recharge to be removed from the blacklist. For those who evade tolls and are blacklisted by ETC, they will not be able to pass through national highways and will be charged based on the longest distance of the entire highway. 2. If the deduction fails due to ETC device failure, you can take the ETC device (electronic tag) to an ETC service outlet or highway service hall for testing. If the damage is not caused by human factors, the device can be reactivated or replaced. 3. To ensure normal fee deduction by the ETC device, avoid placing it in strong magnetic or humid environments. Additionally, when not in frequent use, regularly charge the ETC electronic tag to avoid affecting the battery life inside the ETC device.

What is the repair method for P2015 fault code?

P2015 fault code indicates unreliable signal from the intake manifold runner control sensor/position. This fault usually occurs due to excessive carbon buildup in the intake manifold causing the runner flap to stick. You can observe whether the runner linkage changes during rapid acceleration. If there's no change or minimal change, it's generally recommended to replace the original equipment manufacturer (OEM) assembly. More details are as follows: 1. The P2015 fault code refers to a malfunction in the intake manifold runner position sensor, switch circuit range, or performance. The intake manifold runner control assembly is located between the intake manifold and cylinder head. To improve engine performance, each cylinder corresponds to two intake runners that operate differently - one remains constantly open while the other only opens when engine speed reaches 3000 rpm. 2. Possible causes include: intake manifold runner position sensor or circuit failure, damaged intake manifold runner switching vacuum tank, malfunctioning intake manifold runner electronic valve or its circuit, mechanical failure of intake manifold runner, mismatch between ECU and intake manifold runner sensor, vacuum line leakage, or damaged engine control unit. 3. After troubleshooting, promptly clear the fault code following the vehicle-specific fault code clearing procedure. Always follow proper operating procedures for clearing codes, otherwise similar fault codes may reappear during later driving, making elimination more troublesome.

What is the ECO mode in Mercedes-Benz E300?

ECO refers to the economic driving mode function of a car. ECO is an English abbreviation formed by the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active eco driving mode and non-active eco driving mode. When the eco indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the eco mode switch, the dashboard indicator light immediately illuminates, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The non-active eco mode does not have a dedicated button. When the eco indicator light on the dashboard illuminates, it merely serves as a reminder function. The eco mode automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the eco indicator light. Most vehicles employ the active eco driving mode, which means they have their own switch button. Therefore, the eco mode can be activated during daily driving. However, it is unnecessary to activate the eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not reflect the economic and fuel-saving characteristics of the eco mode and could also affect the vehicle's power. In addition, the eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the vehicle prioritizes speed, causing the eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, the eco mode may also become ineffective. When a high torque output is required, such as when climbing a hill, the engine's computer prioritizes ensuring sufficient power to drive the vehicle, and the eco mode will not function in such cases.
