The sunroof drain holes of the Audi Q3 are located on the left and right sides of the closing joint of the sunroof. Below are some maintenance tips for the sunroof: 1. Pay attention to the condition of the sunroof guide rails: The electric sunroof works smoothly only when the guide rail mechanism is in a 'healthy state'—free of debris, deformation, and well-lubricated. Owners should regularly check the sunroof guide rails. 2. Avoid excessive use of the sunroof: Although the sunroof is part of the car windows, its mechanical structure differs from that of the side windows, so it should not be used too frequently. 3. Do not open the sunroof immediately in cold weather during winter: In northern regions, winters can be extremely cold, and the edges of the sunroof may freeze overnight, making it temporarily impossible to open. In such cases, owners should not attempt to open the sunroof immediately, as accumulated snow in the channels can increase resistance, potentially burning out the sunroof motor if forced. 4. Avoid opening the sunroof on bumpy roads: It is best not to open the sunroof when driving on uneven or bumpy roads, as the jolting can easily damage the sunroof mechanism.

I've driven an Audi Q3 for several years, and the issue of sunroof drainage holes is definitely worth mentioning. Their main locations are at the four corners of the sunroof edges: the front drainage holes are in the grooves near the upper left and right sides of the windshield, while the rear drainage holes are near the C-pillar at the rear window roof. When you open the sunroof, you can clearly see these small holes—they're designed to be quite hidden but practical. Once, I forgot to clean them, and it happened to be the rainy season, resulting in the car's carpet getting completely soaked because fallen leaves got stuck in the holes and blocked the water flow. Cleaning them is actually simple: just use a thin soft tube or a hairdryer on the cool setting to blow them out—avoid using hard objects to prevent damaging the pipes. It's recommended to check them every six months, especially during seasonal transitions, to prevent water from seeping into the interior or electronic components. Audi does a decent job in this regard, but if owners neglect it, the repair costs can be significant.

Do Front and Rear Brake Pads Need to Be Replaced Together?

Front and rear brake pads do not need to be replaced together as they have different replacement cycles. Compared to front brake pads, rear brake pads generally have a longer service life. Under normal driving conditions, front brake pads typically need replacement every 30,000 to 50,000 kilometers, while rear brake pads can last about 60,000 to 100,000 kilometers before requiring replacement. The replacement interval for brake pads is not only directly related to their service life but also depends on the vehicle's driving conditions and individual driving habits. New brake pads are approximately 1.5 cm thick, and when they wear down to only one-third of their original thickness (about 5 mm), they should be replaced promptly. When replacing brake pads, both pads on the same axle must be changed simultaneously to ensure balanced braking performance on both sides.

What brand is Terramax tires?

Terramax is a Sailun tire. Here are some tire maintenance tips: 1. Car tire inspection: During daily driving, it's necessary to check the car tires, especially the tire pressure and wear level. Insufficient tire maintenance poses significant safety risks. When tire wear reaches the indicator mark, immediate replacement is required to avoid risks like skidding during driving. 2. Tire pressure: Tire pressure should be maintained between 200kPa-280kPa. It's best to set the pressure according to the manufacturer's standard. If the vehicle will be parked for an extended period, adjust the pressure to 300kPa.

What to Do When the ABS Light Comes On?

When the ABS light comes on, it indicates a malfunction in the anti-lock braking system. Possible causes include a faulty sensor, issues with the ABS wiring harness, the ABS control module, or the braking system, leading to the failure of the ABS anti-lock braking function. It is important to drive at a low speed to a 4S shop for inspection and repair to eliminate safety hazards. ABS is a vehicle safety control system with advantages such as anti-skid and anti-lock features. It is an improved technology based on conventional braking systems and can be categorized into mechanical and electronic types. ABS not only provides the braking function of a standard braking system but also prevents wheel lock-up, allowing the vehicle to steer while braking, ensuring directional stability, and preventing skidding or deviation.

Where are the accelerator and brake pedals located?

Accelerator and brake pedal positions: Manual transmission vehicles have three pedals, arranged from left to right as the clutch pedal, brake pedal, and accelerator pedal; automatic transmission vehicles have two pedals, arranged from left to right as the brake pedal and accelerator pedal. The brake, also referred to as the deceleration device, is the mechanism used to stop or reduce the speed of moving locomotives, vehicles, other transportation tools, or machinery. In cars, the accelerator, brake, and clutch are separate. The clutch is on the left and is controlled by the left foot, while the accelerator and brake are on the right, both controlled by the right foot. When braking, avoid sudden stops; instead, apply gradual pressure from light to heavy. Frequent sudden braking can easily damage the brake system.

What is the difference between electronic parking brake and auto hold in cars?

Here is the difference between electronic parking brake and auto hold in cars: 1. Different braking duration: Auto hold is a temporary braking system, while the electronic parking brake is for long-term braking. Together, they form an intelligent braking control system that integrates temporary braking during driving and long-term braking after parking, both achieved through electronic control. 2. Different usage methods: The electronic parking brake works like the handbrake in a manual transmission car—you need to release it when driving and engage it when parking. Auto hold, on the other hand, automatically engages and releases the handbrake during driving. The electronic parking brake is suitable for use before and after long-term parking, while auto hold is suitable for stop-and-go traffic conditions.
