When an exclamation mark appears on the car dashboard, there are five possible scenarios: general faults, automatic transmission faults, braking system faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these five situations: General Faults: A triangle with an exclamation mark inside indicates that there is a fault with the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Faults: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating that there is a problem with the transmission or the transmission fluid is below the normal range. The transmission fluid should be replaced promptly. Braking System Faults: A circle with parentheses and an exclamation mark in the middle represents a braking system warning, mainly indicating a fault in the braking system or low brake fluid level. Immediate inspection of the braking system is required to avoid accidents. Abnormal Tire Pressure: A horizontal line with parentheses and an exclamation mark below represents the tire pressure monitoring warning light. This light will illuminate when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Faults: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling that there is a problem with the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.

What is the wheelbase of the Golf?

The wheelbase of the Golf is 2637mm, with body dimensions of 4259mm in length × 1799mm in width × 1476mm in height, positioning it as a compact sedan. The Golf is one of Volkswagen's most iconic models. In 2020, seven variants were launched. In terms of exterior design, it features a new 'X' front face styling, with chrome trim connected to the daytime running lights, extending the visual width. The advanced full-LED taillights and the VW emblem design integrate the trunk-opening function and conceal the rearview camera, which automatically flips open when reversing. In terms of powertrain, it is equipped with three turbocharged engines: 1.2T, 1.4T, and 2.0T, paired with a 7-speed dual-clutch transmission. The 1.2T engine delivers a maximum horsepower of 116PS and a maximum torque of 200Nm, the 1.4T engine produces 150PS and 250Nm, and the 2.0T engine generates 220PS and 350Nm. The Golf's front suspension uses a MacPherson strut independent suspension. The 1.2T model features a torsion beam non-independent rear suspension, while the 1.4T model adopts a four-link independent rear suspension. Independent suspension can enhance the performance of the wheels on the ground, thereby improving traction.

Does an Automatic Transmission New Car Need a Break-in Period?

If the vehicle's user manual does not specify otherwise, an automatic transmission new car does require a break-in period. Here is a detailed introduction to the precautions for breaking in a new car: 1. Pay attention to the break-in mileage: The break-in mileage for a new car is generally 1,000-3,000 kilometers. The initial break-in period is 0-500 kilometers. During this phase, avoid aggressively stepping on the accelerator or brakes, and keep driving speed and engine RPM low—speed should not exceed 70 km/h, and engine RPM is best kept below 2,000 rpm. The mid-term break-in period is 500-1,000 kilometers, during which driving speed and engine RPM can be moderately increased, but speed should not exceed 90 km/h, and the engine's maximum RPM can reach 2,500 rpm. The late-term break-in period is 1,000-3,000 kilometers. On good road conditions, speed can be increased up to 120 km/h, and the engine's maximum RPM can be raised to 3,000 rpm. To maintain the engine's vitality, avoid high RPM operation while driving—the lower the RPM, the better—otherwise, it may cause engine damage. 2. Emphasize warming up the car: Do not start driving immediately after starting the car. Wait until the coolant temperature reaches the normal operating range before moving. Especially in cold winter, gently press the accelerator pedal to allow the engine to operate at a slow pace. If you cannot warm up the car before driving, drive at low speed for the first 5 minutes after starting, and only accelerate once the coolant temperature is sufficiently high.

How to Distinguish Between Reiz Versions?

Distinguishing between Reiz versions is quite simple. The Reiz was available in China for a total of twelve years, during which it underwent only two generational updates. Comparing the first-generation and second-generation models, the differences are as follows: 1. Power differences: The first-generation model had slightly more power than the second-generation, though the difference was minimal. For the 2.5L models, the first-generation had a maximum horsepower of 197PS, while the second-generation had 193PS. For the 3.0L models, the first-generation had a maximum horsepower of 231PS, while the second-generation had 227PS. 2. Throttle tuning differences: The first-generation Reiz had more responsive throttle tuning compared to the second-generation. 3. Steering feel differences: The second-generation Reiz had better steering than the first-generation. The steering in the second-generation felt more precise, with heavier power assistance, resulting in a more stable overall feel.

What does the SS on the car dashboard mean?

SS on the car dashboard is the auto start-stop indicator light. This light turns on when the start-stop function is activated and turns off when it's deactivated. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. This is achieved by equipping a traditional engine with an enhanced motor that has idle start-stop functionality, allowing the engine to completely shut down when idle stop conditions are met. When the vehicle needs to move again, the idle start-stop motor system quickly responds to the driver's start command, rapidly restarting the engine for seamless transition, thereby significantly reducing fuel consumption and exhaust emissions.
