If the Yidong key is out of battery, you can pull out the mechanical key inside the smart key, use the mechanical key to open the door, place the key close to the bottom layer of the cup holder, and then start the vehicle with the ignition button. The method to replace the battery of the Yidong key: 1. Use a slender tool to pry open the upper and lower shells of the key; 2. Remove the old battery; 3. Install the new battery, ensuring the positive pole of the battery aligns with the positive pole on the battery fixing plate; 4. Reassemble the circuit board with the new battery into the key shell and press the shells together. Taking the 2020 Blue Whale Fengshang Yidong as an example, its body dimensions are: length 4730mm, width 1820mm, height 1505mm, with a wheelbase of 2700mm.

Last time my EADO key also ran out of battery, and the car was locked and couldn't be opened. Fortunately, I noticed a small slot on the back of the key. Pulling it out revealed the mechanical key. After using it to open the door and getting inside, remember to press the brake pedal and place the key near the one-button start, about 5 centimeters away. Once the dashboard lights up, the car starts successfully. This induction design is really smart. The battery is a CR2032 coin cell, which can be replaced for a few dollars at a repair shop or supermarket. It's a good idea to keep a few spare ones in the car. Don't panic; just try a few more times. These small issues are common, so it's good to develop the habit of regularly checking the key's battery indicator light to avoid awkward situations. Now I'm used to it and always keep a spare key in my bag for emergencies.

Which vehicles can be charged by EV Power charging piles?

EV Power charging piles can charge all new energy electric vehicles. EV Power charging piles are divided into two types: AC charging piles and DC charging piles. AC charging piles are for slow charging, while DC charging piles are for fast charging. Power of EV Power AC charging piles: The power is generally 7KW/14kW, etc., and electric vehicles generally support AC charging. EV Power DC charging piles convert 380V power into high-current DC charging voltage through a transformer, with a charging current that can reach 32A and a charging power that can reach 45KW. EV Power fast charging pile equipment adopts an integrated AC/DC structure. It can achieve both DC charging and AC charging. During the day when there is more charging business, the DC method is used for fast charging. At night when there are fewer users at the charging station, AC charging can be used for slow charging operations. According to the installation location, they can be divided into public charging piles and dedicated charging piles: Public charging piles are built in public parking lots combined with parking spaces to provide public charging services for social vehicles. Dedicated charging piles are built in the parking lots of construction units for use by internal personnel. Private charging piles are built in personal parking spaces to provide charging for private users. Charging piles are generally built in combination with parking spaces in parking lots. The protection level of charging piles installed outdoors should not be lower than IP54. The protection level of charging piles installed indoors should not be lower than IP32.

Will You Lose Points for Taking Both Hands Off the Steering Wheel in Subject Two?

Taking both hands off the steering wheel in Subject Two will result in an immediate deduction of 100 points and be treated as a failure, as this constitutes dangerous driving behavior. Point deduction items in the Subject Two test: Not fastening the seatbelt and closing the car door properly, the car body crossing the line, stopping midway, exceeding the time limit, and the wheels pressing the solid edge line will all result in a 100-point deduction. Incorrect use of lights and stalling once will deduct 10 points. Failing to stop at the designated spot will deduct 100 points. If the front bumper of the car does not reach the control line after stopping, 100 points will be deducted. If the car rolls back more than 30 centimeters after stopping, 100 points will be deducted. If the car rolls back less than 30 centimeters after stopping, 10 points will be deducted. Correct steering wheel handling: First, you need to master a safe steering wheel grip. The left hand should grip the steering wheel near the 9 o'clock position, and the right hand near the 3 o'clock position. Both hands should grip the steering wheel firmly yet remain relaxed, not tense. The thumbs should naturally rest on the steering wheel. When turning the steering wheel, the hands should alternate in turning. When the steering wheel completes one full rotation, the left hand turns halfway, followed immediately by the right hand continuing the turn.

What is the ground clearance of the Fit?

The ground clearance of the Fit is 240mm. The minimum ground clearance of the Fit refers to the distance between the lowest point (excluding the wheels) and the supporting plane, which indicates the vehicle's ability to pass over obstacles such as rocks and stumps without collision. A higher ground clearance of the Fit improves its off-road capability, but if the ground clearance is too high, the stability at high speeds may decrease. The Fit is a hatchback launched by GAC Honda. The third-generation Fit was released on May 29, 2014, positioned as a "cool hatchback" targeting the younger generation of "post-90s" who seek individuality, with a spacious interior. The Fit has a wheelbase of 2530 mm, and its length, width, and height are 4109 mm, 1694 mm, and 1537 mm, respectively. Generally, the ground clearance of sedans ranges between 110 mm and 150 mm, while SUVs have a ground clearance between 200 mm and 250 mm. However, the ground clearance of the Fit is not static; it also depends on the load condition. Therefore, changes in ground clearance should be considered based on the Fit's load variations. When selecting a vehicle, ground clearance can be one of the reference factors for choice. It depends on the vehicle's intended use and the road conditions. For urban areas with good road surfaces, choosing a vehicle with lower ground clearance can enhance stability and comfort. If traveling frequently to remote areas or driving on poor road conditions, considering the vehicle's off-road performance, a higher ground clearance may be preferred to avoid scraping or damaging the chassis.
