Does the Geely Emgrand support wireless CarPlay?

The new Geely Emgrand supports wireless CarPlay. The relevant introduction of CarPlay is as follows: Introduction to CarPlay: CarPlay is an in-car system released by Apple Inc. in the United States, which seamlessly integrates users' iOS devices and iOS experience with the dashboard system. Interfaces supported by CarPlay: CarPlay only supports iPhone models with a Lightning interface. Although the iPad also supports this interface, Apple has not listed the iPad as a hardware device supported by CarPlay. On June 13, 2016, Apple announced at the WWDC developer conference that its smart car system CarPlay would be updated alongside iOS 10, becoming the perfect companion for the new Apple Maps and Siri.

What is the normal fuel rail pressure for the Audi A6L?

A6LC6 model, if it is a gasoline direct injection engine, the low-pressure side fuel pressure is about 4bar at idle, and up to about 6bar during rapid acceleration. For the 2.0T engine, the fuel filter comes with a pressure regulator, and the rated maximum pressure is 6BAR. More information about the fuel pressure regulator is as follows: 1. Introduction: The fuel pressure regulator is a component that ensures normal fuel pressure in the car's fuel system. Inside the pressure regulator, there is a diaphragm that controls the opening and closing of the pressure valve. When the fuel pressure drops below a certain value, the pressure valve closes, and the fuel pump pressurizes to increase the pressure in the fuel line. When the pressure exceeds the specified value, the diaphragm opens, and the excess fuel flows back to the fuel tank through the return line, reducing the pressure. 2. Function: The function of the fuel pressure regulator is to adjust the fuel pressure entering the injector based on changes in the intake manifold pressure, maintaining a constant pressure difference between the two. This ensures that the amount of fuel injected from the injector depends solely on the injector's opening time, allowing the ECU to precisely control the fuel injection amount by adjusting the injection duration.

Should tires be replaced after seven years if the wear is not severe?

They need to be replaced. Tires are rubber products, and over time, the rubber will age. Even if the tread is relatively intact, tires that have exceeded their lifespan must be replaced because aged tires are highly prone to bursting. The typical lifespan of a tire is 3-5 years. A tire that has been used for seven years has exceeded its service life, significantly compromising safety performance, and must be replaced. Tires should not continue to be used under the following circumstances: 1. If the tire is worn: Tires have tread wear indicators, which are slightly raised marks located at the bottom of the tread grooves, with a height of 1.6 mm (the legal minimum groove depth). If the tread rubber wears down to the same level as these raised indicators, the tire should be replaced immediately, as continued driving is no longer safe. Using worn tires on wet roads can lead to "hydroplaning," increasing the risk of losing control of the vehicle. This is because excessively worn tires cannot effectively channel water away from beneath the tire, potentially causing loss of control. 2. If the tire is damaged: Hitting curbs, falling into potholes, or punctures from nails can severely damage tires. Damaged tires may be repairable, but only a professional repair shop can accurately determine whether a tire can be repaired or must be replaced. Generally, sidewall damage cannot be repaired, and for safety reasons, the tire must be replaced. 3. If the tire has aged: If the tread shows deformation or significant cracking, stop using the tire immediately and have it inspected by a professional repair shop to determine if it can still be used. 4. If the tire has a bulge: Tire bulges are a major cause of blowouts, especially on highways, posing a serious hazard. Tires with bulges should be replaced promptly.

Will I be penalized for crossing the solid line at a highway exit by mistake?

Crossing the solid line at a highway exit by mistake will result in penalties. If a driver accidentally crosses the solid line at a highway exit, according to relevant regulations, driving a motor vehicle in violation of prohibition signs or markings will incur a 3-point penalty. Violating prohibition markings refers to driving over lines that are prohibited, which include solid yellow lines and large yellow crosses on the road (indicating no parking). Crossing these lines constitutes a violation. Motor vehicle violations of prohibition markings include: 1. Crossing or driving over solid single or double yellow lines while driving; 2. Parking temporarily or for an extended period in no-parking zones; 3. Making U-turns in no-U-turn zones or turning left at intersections where left turns are prohibited—all of these actions are considered violations of prohibition markings.

How many points are deducted for driving in the wrong direction on the highway?

Driving in the wrong direction on the highway results in a deduction of 12 points and may lead to a 12-month suspension of the driver's license, as well as possible administrative penalties. Driving in the wrong direction on the highway is a particularly severe form of wrong-way driving. If a motor vehicle driver accumulates two or more instances of 12-point deductions or a total of 24 or more points within a single scoring cycle, the vehicle management office must also conduct a road driving skills test within ten days after the driver passes the examination on road traffic safety laws, regulations, and related knowledge. For those undergoing the road driving skills test, the examination will be based on the highest vehicle class permitted by their driver's license. If the test is passed, the points will be cleared, and the driver's license will be returned. If the test is failed, the driver must continue to participate in study and retake the test. Those who refuse to participate in study or take the test will have their driver's license suspended by the traffic management department of the public security authority.

How much over 120 km/h speed limit is considered speeding?

On highways with a 120 km/h speed limit, driving at 132 km/h is considered speeding, but within 10% over the limit, only a warning will be issued without penalty. When driving on roads with speed limits above 100 km/h, exceeding the limit by more than 10% but less than 50% will result in fines and point deductions. However, violations within 10% over the limit will only receive a warning without fines or point deductions. According to Article 42 of the Road Traffic Safety Law: Motor vehicles driving on roads shall not exceed the maximum speed indicated by speed limit signs; on road sections without speed limit signs, safe driving speed shall be maintained; when driving at night, on hazardous road sections, or under adverse weather conditions such as sandstorms, hail, rain, snow, fog, or icy roads, driving speed shall be reduced.
