Where to Place the ETC in a Car?

The ETC is generally installed on the upper middle part of the front windshield for regular vehicles, while for large vehicles like trucks and buses, it is installed on the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with anti-explosion film or those that have it installed later, which may affect the signal transmission of the microwave communication link, the ETC should be installed on the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for it, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle license. If the application is made by someone other than the owner, the agent's valid ID card is also required. The photocopy of the vehicle license should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. For company vehicles, the required documents include: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle license; and the vehicle that needs the ETC. Here are some precautions for installing ETC: Do not obstruct the view; it's best to install it behind the rearview mirror: Many car models have windshields with a large rear tilt angle, which can reduce the driver's field of vision. Installing the ETC without considering this can increase the driver's blind spots. Install it on the right side behind the rearview mirror to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a solar panel on the back for self-charging. Therefore, avoid installing it on the black areas of the windshield or positions that may block the solar panel. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield will press the lever in. If removed, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable, requiring a visit to an ETC service point for unlocking. This is designed to prevent multiple vehicles from sharing one device. When using ETC, note that: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic toll payment for the front vehicle. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information, leading to toll deduction failure. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failure.

Where should the ETC be installed?

The ETC is generally installed on the upper middle part of the front windshield for regular vehicles, while for large vehicles like trucks and buses, it is installed on the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with anti-explosion film or those that have been retrofitted with anti-explosion film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle license.

For company vehicles, the required documents include: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle license; and the vehicle that needs to have ETC installed. Here are some precautions for installing ETC: Do not obstruct the view. It is best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt angle, which reduces the driver's field of vision. If this is not considered during ETC installation, it can increase the driver's blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself.

When using ETC, note the following: The ETC transaction sensing area is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic toll deduction for the wrong vehicle. The ETC lane recognition speed is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle's device information, leading to toll deduction failure. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failure.

What causes car shaking when pressing the accelerator deeply?

The reasons for car shaking when pressing the accelerator deeply are: 1. Ignition system: Spark plug issues, which could be due to expired lifespan or excessive carbon buildup. The solution is to replace the spark plugs; 2. Intake system: A dirty throttle body or oxygen sensor, which can lead to an improper air-fuel mixture ratio, naturally causing shaking. The solution is to clean the dirty parts; 3. Fuel system: Common causes include injector failure, fuel pump issues, or clogged fuel filters. The accelerator, also known as the 'throttle' or 'gas pedal', is the control device that regulates engine power (thrust). In piston aircraft engines, the throttle controls the carburetor's throttle opening to adjust cylinder filling, thereby determining the engine's output power.

What is the normal RPM for an automatic transmission?

Automatic transmission normally operates at around 1800 to 2000 RPM. The prerequisite for upshifting is acceleration, while the prerequisite for downshifting is deceleration. Higher gears are more fuel-efficient, but this doesn't necessarily mean higher speeds. Lower gears can also operate at high speeds, providing strong power for climbing hills, though they consume more fuel. Whenever road conditions permit, it's advisable to use higher gears. An automatic transmission typically refers to a car's automatic gear-shifting mechanism, where the transmission control system automatically selects the appropriate gear based on engine speed and load, replacing the driver's subjective judgment and manual shifting operations. Most automatic transmission cars have six gear positions, arranged from top to bottom as: P, R, N, D, S, L.

What does the BYD Qin EV function restriction mean?

BYD Qin EV function restriction generally indicates damage to the vehicle's high-voltage system. Below are the relevant details: 1. Handling EV function restriction: When the car displays an EV function restriction, it is essential to promptly take it to a repair shop or 4S dealership for professional maintenance to avoid unnecessary issues during vehicle use. 2. Detailed introduction to EV: EV is the English abbreviation for electric vehicles. On hybrid vehicles, the full name of EV is HEV, which stands for hybrid electric vehicle. Hybrid power means the car uses both gasoline and electric power as driving methods. The advantage is that when the vehicle starts or stops, it relies solely on the generator. The engine does not work until a certain speed is reached. Therefore, the engine can always maintain optimal working conditions, with good power performance and very low emissions. Moreover, the source of electrical energy is the engine.
