How to Locate the Fuel Filter in Mercedes-Benz GLA?

The fuel filter is located near the fuel tank at the rear underside of the vehicle, and the model number of the fuel filter is GLA45. Below is relevant information about Mercedes-Benz fuel filters: 1. The filter element of the fuel filter mostly uses filter paper, and some fuel filters use nylon cloth or polymer materials. The main function is to filter out impurities in the gasoline. 2. The role of the fuel filter is to remove water and impurities from the gasoline. Below is relevant information about replacing the filter: 1. First, remove the vehicle key and disconnect the fuel pump fuse or the vehicle power supply to prevent the fuel pump from pumping out gasoline during disassembly. 2. Next, remove the rear seat cushion and the cover on the fuel pump, at which point you can see the fuel pump assembly. 3. The fuel pump assembly is secured by a black retaining ring. After disconnecting the wiring harness and fuel lines on the fuel pump, a special tool is required to remove this retaining ring. 4. After removing the retaining ring, the fuel pump assembly can be taken out. Replace the corresponding components of the old fuel filter with the new fuel filter assembly.

How to Determine Brake Fluid?

Brake fluid can be seen on the exterior of the reservoir, which has markings. If the brake fluid is depleted, the brake warning light on the dashboard will illuminate. Here is relevant information about brake fluid: Methods for selecting brake fluid: 1. First, since the seals in the braking system are rubber components, prolonged immersion in brake fluid can cause chemical changes. 2. Second is the high-temperature performance, which refers to the brake fluid's ability to resist vapor lock at high temperatures. This is evaluated using the "equilibrium reflux point" metric. 3. Third is the low-temperature performance of the brake fluid, which refers to its flow characteristics at low temperatures. This is assessed by measuring the kinematic viscosity of the brake fluid at 40°C. If the viscosity is too high at this temperature, it can affect the transmission of braking force. 4. Fourth, since many components in the automotive braking system are made of metal, high-quality brake fluid should contain various anti-corrosion additives to prevent corrosion of the braking system.

Is Tire Shine Harmful to Tires?

Tire shine is not harmful to tires. Tire shine, also known as tire dressing, helps maintain long-lasting cleanliness of tires, and qualified tire shine products are harmless to tires. The functions of tires include: 1. Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and moments in other directions; 2. Transmitting traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the vehicle's power performance, braking performance, and passability; 3. Preventing severe vibrations and premature damage to automotive components, adapting to the high-speed performance of the vehicle while reducing driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.

How Long Can Tires Be Used?

Tires should generally not be used for more than 3 years or exceed 60,000 kilometers in mileage. While slightly surpassing these limits may not cause major issues, winter's low temperatures and summer rains can reduce the tire's wet grip and dry handling performance. Pay close attention to the sidewalls: As tire rubber gradually ages, deep cracks may appear on the sidewalls. As long as the sidewalls haven't been impacted and the cords remain intact, the tires can continue to be used. The triangular marks on the tire sidewalls can help drivers locate a protrusion in the tread grooves, which indicates the actual wear limit of the tire. That value should be greater than 1.6 millimeters.

Is Wheel Balancing Necessary During Tire Rotation?

Tire rotation does not require wheel balancing, as it merely involves swapping the positions of the wheels without altering the mass balance between the tires and rims. Therefore, dynamic balancing of the tires is unnecessary. However, when installing new tires, which involves changing the mass distribution of the wheel assembly, dynamic balancing is required. Automotive tires are one of the critical components of a vehicle, directly contacting the road surface and working in conjunction with the suspension system to absorb shocks during driving. Structurally, tires can be categorized into radial tires and bias-ply tires. Based on tread patterns, they can be classified into rib tread tires, lateral tread tires, mixed tread tires, and off-road tread tires.

What does the car's ECO prompt mean?

ECO indicates that the vehicle's economical driving mode is activated. ECO is an English abbreviation derived from Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and passive Eco driving mode. When the ECO indicator light on the dashboard illuminates, it signifies that the vehicle's economical mode is engaged. The Eco mode can be either active or passive. The key difference lies in the fact that the active mode has a dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The passive Eco mode does not have a dedicated button. When the dashboard ECO indicator light illuminates, it serves merely as a reminder function. The Eco system 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, meaning they have a dedicated switch button. Therefore, during daily driving, we can generally activate the Eco mode. However, it is unnecessary to engage Eco mode when driving over 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of Eco mode but also negatively impact the vehicle's power performance. Additionally, the Eco mode typically deactivates under the following conditions: When the vehicle speed exceeds 120 km/h, the system prioritizes speed, causing the Eco mode to deactivate automatically. During idle parking or when in N/P gear or manual mode, the Eco mode may also deactivate. When high torque output is required—such as when climbing a hill—the engine control unit prioritizes delivering sufficient power to drive the vehicle, and the Eco mode will not operate under these circumstances.
