Haval F7 radar system malfunction is caused by: 1. The working power supply or grounding circuit of the reversing radar system is not functioning; 2. Missing power supply to the controller, loose connection of the reversing radar probe plug, damaged buzzer, or loose connection of the buzzer plug. The body dimensions of the Haval F7 are: length 4620mm, width 1846mm, height 1690mm, with a wheelbase of 2725mm. The Haval F7 is equipped with a 1.5L turbocharged engine, with a maximum power of 124kW, a maximum power speed range of 5000 to 5600 rpm, a maximum torque of 285Nm, and a maximum torque speed range of 1400 to 3000 rpm, paired with a 7-speed dual-clutch transmission.

As a frequent driver of a Haval F7, I've noticed that radar system failures are not uncommon. The most common issue is the radar probe being covered by mud or debris, like when I park under trees, bird droppings or leaves block the signal, causing it to malfunction. Another issue is wiring problems; excessive vibration can loosen connections or blow fuses, and simply replacing a fuse costs just a few dollars. Occasionally, the system software may glitch, similar to a phone freezing, requiring a restart or software update. If the sensor itself is damaged, it needs to be checked at a 4S shop, which can be more costly. A faulty radar has significant impacts, making it easier to hit objects while parking and increasing risks when adaptive cruise control fails on highways. I recommend developing habits like gently wiping the radar probe with a damp cloth during car washes, checking the relevant fuses in the fuse box monthly for signs of melting, and tightening connections to prevent loosening. Radar signals are weaker in humid or rainy weather, so manual operation is safer. These small details can prevent major troubles. After years of driving, I've learned that prevention is better than repair.

Can You Drive with an Expired Temporary License Plate?

Temporary license plates cannot be used on the road once expired. Relevant information is as follows: 1. Regulations: Vehicles that have not obtained a formal license plate after the expiration of the temporary license plate are not allowed to drive on the road. According to the "Road Traffic Safety Law," this situation is equivalent to "failing to display a license plate as required." The penalty for "failing to display a license plate as required" under the "Road Traffic Safety Law" is a fine of 200 yuan and 12 demerit points. 2. Introduction to temporary plates: After obtaining a temporary license plate, the owner should carefully verify the information on it. The front of the temporary plate must clearly print the validity period, while the back should include information fields such as the engine number, chassis number, issuer, issuance date, etc., all of which must correspond to the vehicle and the issuer's information. Each item should be accurate and complete. If a temporary plate does not meet the above requirements, you can file a complaint with the Vehicle Management Office of the Traffic Police Brigade under our bureau.

Is ETC Card Skimming Real?

ETC cards inserted in vehicles can be skimmed, so it is recommended to remove the ETC card when parking to prevent unauthorized transactions. Precautions for ETC Usage: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of over 10 meters to prevent automatic fee deduction for the preceding vehicle in case of ETC device malfunction or absence. The recognized speed for ETC lane passage is 20km/h. Excessive speed may result in failure to read vehicle device information and unsuccessful fee deduction. Unauthorized removal or movement of OBU devices, detachment or loosening of ETC electronic tags may render them ineffective. These can be taken to the issuing bank or highway service center for inspection. Non-deliberate loosening or detachment only requires reactivation. When using a debit card linked to ETC, insufficient balance may cause fee deduction failure. Follow on-site staff guidance to use manual MTC lanes with cash or card payment. Excessively thick windshields may cause poor signal reception. This is particularly noteworthy for vehicles with replaced windshields after accidents or modified front windshields.

How to Identify a Stock Car When Buying a Car?

Here are the methods to identify a stock car: 1. Check the production nameplate: Usually, there is a nameplate on the lower part of the B-pillar on the right side (passenger side) of the vehicle, which indicates the production date of the vehicle, engine parameters, and other information, making it easy to see. 2. Check the glass: The production date of the glass is marked on the car glass. The number represents the year, and the black dots represent the month. If the black dots are in front, subtract the number of black dots from 7; if the black dots are behind, subtract the number of black dots from 13 to get the month. 3. Check the tires: It may not be 100% certain whether the car is a stock car, but the production date of the tires can give a rough estimate of the production time. The four-digit number indicates the week (first two digits) and the year (last two digits). By observing the tires, you can preliminarily judge whether the car has been driven many miles since production. New car tires should be relatively clean, and the tire hairs should still be intact. 4. Check the engine compartment: Open the engine hood and see if it is clean. If it is particularly dirty or has a lot of dust, it indicates that the car has been parked in a harsh environment.

What is the fuel consumption of the Qashqai?

The fuel consumption of the Qashqai is 6.8-7.3L/100km. Additional Information: Methods to reduce fuel consumption are as follows: 1. Regular maintenance: Regular maintenance can reduce the failure rate of the car and also lower fuel consumption. Maintenance includes replacing parts such as spark plugs, oil filters, brake fluid, radiator coolant, air filters, power steering fluid, transmission fluid, etc. Keeping the vehicle in optimal condition helps reduce fuel consumption. 2. Avoid hard acceleration: Hard acceleration only shortens driving time by 4%, but increases fuel consumption by 37%-40%. On typical urban roads, the speed is usually maintained at 50 km/h, with engine RPM around 2000-2500. On highways, the speed is generally 90-110 km/h. For every 10 km/h increase in speed, fuel consumption increases by 10%. Avoid hard acceleration as RPM is the biggest factor affecting fuel consumption. 3. Reduce weight: For every 100KG increase in vehicle weight, fuel consumption increases by 4%-5%. 4. Maintain tire pressure within the normal range: Checking tire pressure not only benefits fuel consumption but also ensures driving safety. Develop a habit of checking tire pressure daily. Generally, the front tire pressure should be 2.2-2.3, and the rear tire pressure should be 2.4-2.5.

What kind of engine oil can be used for the Mazda 3 Axela?

The manufacturer recommends 0W-20 full synthetic or 5W-30 semi-synthetic engine oil for the Mazda 3 Axela. The oil filter models for the Mazda 3 Axela are: Mann: W67/1, Bosch: 0986AF0063, Mahle: OC980. Below are the precautions for using engine oil in the Mazda 3 Axela: 1. For new cars under normal driving conditions, if synthetic oil is used, the oil can generally be changed every 10,000 kilometers, and in some cases, it can even be extended to 20,000 kilometers. 2. "Normal driving" refers to frequent highway driving with minimal stop-and-go traffic. However, if you often drive in the city, encountering traffic lights everywhere and frequent traffic jams, with most trips not exceeding more than a dozen kilometers, this type of driving is considered "severe driving." Under "severe driving" conditions, engine wear is greater, and the requirements for engine oil are higher. Therefore, it is recommended to shorten the oil change interval to effectively protect the engine. 3. After prolonged use, engine oil accumulates a large amount of impurities. If the oil is not replaced in time, these impurities can wear down the engine and shorten the vehicle's lifespan.
