First, turn off the engine, shut down the vehicle, and cut off all power. Then, restore the power and check if the central control screen returns to normal by tapping on it. If the above methods fail to resolve the issue, it is best for the owner to immediately visit a 4S dealership for further assistance.

Can You Wear a Hat During Subject 2 Driving Practice?

There are no strict regulations on whether you can wear a hat during Subject 2 driving practice, so it is allowed. However, it is not recommended because wearing a hat while driving can obstruct your vision and easily lead to traffic accidents. The test items for small cars (C1, C2) include five mandatory tests: reverse parking, parallel parking, stopping and starting on a slope (canceled for C2), right-angle turns, and curve driving (commonly known as S-curves). Some regions also include a sixth item: high-speed toll card collection. The test items for large vehicles (A1, A2, A3, B1, B2) include: pole test, stopping and starting on a slope, parallel parking, crossing a single-plank bridge, curve driving, right-angle turns, passing through a limited-width gate, navigating continuous obstacles, driving on bumpy roads, narrow road U-turns, as well as simulated scenarios such as highways, continuous sharp mountain curves, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling. Subject 2 is scored out of 100, with evaluation criteria for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed under the following conditions: ① For large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. If you fail the Subject 2 test on the first attempt, you are allowed one retake. If you do not take the retake or fail the retake, the test is terminated, and the applicant must reschedule the test after ten days. During the validity period of the driving skill test permit, the number of test reservations for Subject 2 and Subject 3 road driving skills tests must not exceed five. If the fifth reservation still results in a failure, the scores of other previously passed subjects will be invalidated.

What brand is the Hongqi tire?

There are two brands of tires for the Hongqi H5: one is the Hankook Ventus S1 evo2 series tire, with a size of 225/45R19, and the other is the Hankook KINERGY EX series tire, with a size of 225/55R17. The following is a related introduction to car tires: 1. Introduction one: Car tires are one of the important components of a vehicle. They directly contact the road surface and, together with the car suspension, mitigate the impacts experienced during driving, ensuring good ride comfort and smooth driving. They also ensure good adhesion between the wheels and the road surface, improving the car's traction, braking, and off-road capability, while bearing the weight of the vehicle. The important role tires play in cars is increasingly being recognized. 2. Introduction two: Passenger car wheels generally use radial tires. The specifications of radial tires include width, aspect ratio, inner diameter, and speed limit symbols.

What to do when the Ford Kuga 4WD overheats and temporarily becomes ineffective with ABS failure?

When the car displays "4WD overheating temporarily ineffective," it indicates an overheating alarm from the electronic coupler in the four-wheel-drive transmission system. Structure of the electronic coupler: The electronic coupler can form switching circuits, logic circuits, and high-voltage voltage regulator circuits, making it a crucial component in automotive circuits. Couplers mainly include directional couplers, power dividers, and various microwave branch devices, consisting of two parts: a free light source and a photodetector. Troubleshooting methods: As a four-wheel-drive vehicle, when the coupler in the transmission system triggers an alarm, it is promptly reflected on the car's dashboard to alert the driver. Timely disconnection of the electronic coupler can prevent severe circuit failures in the vehicle and even avoid potential self-ignition incidents.

What are the impacts after repairing a water-damaged engine?

The impact of repairing a water-damaged engine is that the engine requires major overhaul. When the cylinders are filled with a large amount of water, the engine crankshaft cannot rotate at all. Since water is incompressible, the pistons have almost no room to move upward. At this point, even if the ignition switch is turned on, the starter motor will not be able to rotate. Below are the relevant introductions to car maintenance: 1. Exterior inspection: Before driving, check the doors, engine hood, trunk, and glass conditions. Inspect for any body damage, body tilting, oil or water leakage, etc. 2. Engine and various fluids: Check the fixation status of engine components and inspect for any oil or water leakage at engine joints. Adjust and tighten belts, and check the fixation of pipelines and wiring. Top up engine oil, coolant, and electrolyte as needed. 3. Tires: Inspect tire wear and clean the trunk. Replace tires when they approach the wear indicators. Check for bulges, abnormal wear, aging cracks, or hard damage on tires. 4. Cleaning and lubrication: Clean oil stains from the engine compartment cover, door hinges, and trunk hinge mechanisms, then lubricate them. The general service life of antifreeze is 2 years; it should be replaced during maintenance, and the cooling system should be thoroughly cleaned. Due to the hygroscopic nature of the braking system, brake fluid should be replaced every two years.
