As an owner who has driven an Infiniti Q50L for several years, I can share my experience: My car is the 2018 model, and the original run-flat tire specification is 245/40 R19, with the brand being Dunlop Sport Maxx RT2. Run-flat tires are quite practical; if the tire gets damaged, you can still drive up to 80 kilometers to find a repair shop without the hassle of changing to a spare tire like with regular tires. I think this design enhances driving safety, especially when encountering problems on the highway at night. However, the downside is that sometimes the ride feels bumpier, particularly when driving over rough roads. The tire specifications must match the rim size, otherwise, it can affect handling. I recommend new owners check the configuration sheet to confirm the specific model when buying the car, and regular maintenance of tire pressure can extend the service life.

I drive a 2020 Q50L equipped with run-flat tires, typically the Bridgestone Potenza S001 in size 255/35 R19. These tires look quite stylish, and their run-flat feature really saved me when I had a puncture, allowing me to drive straight to the repair shop. However, they can be a bit noisy on long drives, not as quiet as the regular tires on my friend's car. The reinforced sidewalls of run-flat tires make them more durable, but replacing a full set costs around 2,500 yuan, which is slightly expensive but worth it. Remember to have the mechanic check tire wear during every maintenance service to avoid imbalance. Road safety is crucial, and these tires help reduce the risk of accidents.

The Infiniti Q50L commonly uses run-flat tire specifications, with rear-wheel-drive models often equipped with 245/40 R19 or 255/35 R19. I use the former, which is the Dunlop brand. Run-flat tires can travel 50-80 kilometers without air pressure, but it's essential to ensure the wheel rim data matches to avoid instability. Their sturdy sidewalls enhance safety after a blowout, though they offer less comfort. When replacing tires, pay attention to tread depth and tire pressure monitoring.

What are the functions of the engine start-stop system?

Engine automatic start-stop function: When the vehicle is waiting at a red light, stepping on the brake pedal will cause the vehicle to stop. After three seconds, the engine will automatically shut off, putting the engine in a dormant state. When the light turns green, releasing the brake pedal will automatically restart the engine, allowing the vehicle to shift gears and proceed. The following are the advantages and disadvantages of the automatic start-stop system: 1. Advantages: Saves fuel and reduces exhaust emissions. 2. Disadvantages: The automatic start-stop function imposes strict requirements on the battery. Mainly, vehicles equipped with this function require larger batteries and higher-quality starter motors. Consequently, the maintenance and repair costs in the long run are relatively higher.

What does it mean when the ETC displays 'OBU disassembled'?

When the ETC displays 'OBU disassembled,' it may be caused by the user's unauthorized disassembly or relocation of the OBU device. It could also be due to the detachment or loosening of the electronic tag, which might trigger the anti-tamper switch, leading to OBU failure. Solution: Take it to the bank where the ETC card was issued for inspection. If the loosening or detachment was not caused by human intervention, simply reactivate it. ETC activation method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays 'Bluetooth is on.' If inserting and removing twice without attaching the electronic tag shows 'Tag invalid,' this is normal and does not affect activation. Alternatively, you can directly press the button on the top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually, there is a download QR code on the electronic tag), and enter the device activation interface. Click 'Connect Device' and wait patiently for the 'Connection successful' prompt. Once connected successfully, upload a photo of the vehicle's front to complete the activation.

What Types of Vehicles Can Use the Hong Kong-Zhuhai-Macao Bridge?

Currently, only five types of vehicles are permitted to cross the bridge: freight vehicles, shuttle buses, cross-border taxis, cross-border coaches, and cross-border private cars. Below are the relevant details: 1. Cross-border private cars refer to vehicles with dual license plates from Guangdong and Hong Kong. Previously approved Guangdong-Hong Kong dual-plate vehicles for the Huanggang, Wenjindu, Shatoujiao, and Shenzhen Bay ports can directly use the bridge without additional approval (temporarily set for two years). Private cars without Guangdong-Hong Kong dual license plates are not allowed on the bridge. Currently, Guangdong-Hong Kong cross-border freight vehicles can pass through the Hong Kong-Zhuhai-Macao Bridge without additional procedures (excluding trucks traveling to and from the Futian Free Trade Zone). 2. Trucks with Guangdong-Hong Kong dual license plates (excluding those traveling to and from the Futian Free Trade Zone) can directly use the bridge. Passengers must carry relevant cross-border travel documents. The shuttle buses on the Hong Kong-Zhuhai-Macao Bridge are divided into "Hong Kong-Macao Line" and "Hong Kong-Zhuhai Line," with half-price discounts for children and seniors. Shuttle buses only operate between ports and do not enter urban areas.
