Precautions for driving through a tunnel: 1. No overtaking: In general two-lane tunnels, drive at a normal speed on the right side of the road. Do not change lanes inside the tunnel, and absolutely avoid overtaking. Speed limit signs are usually prominently displayed at the tunnel entrance, and there are also speed limit reminders inside the tunnel. Maintain a normal speed and do not exceed the limit. 2. Drive on the right: When passing through a two-way tunnel, drive on the right side of the road. Turn on your lights as needed, pay attention to oncoming vehicles, and avoid honking inside the tunnel. When approaching the tunnel, carefully observe traffic signs or information boards. Pay special attention to height restrictions for trucks, and vehicles exceeding the height limit are strictly prohibited from entering the tunnel. Do not rely on intuition to judge your speed inside the tunnel; always confirm your speed using the speedometer and maintain an appropriate following distance.

On long-distance drives, I love studying driving details, and my biggest fear in tunnels is visual traps: you must turn on the low beams 100 meters before entering the tunnel, which is roughly the distance of ten utility poles. Rolling down the windows and turning off the music helps detect unusual sounds. The blinding white sunlight when exiting the tunnel is the most dangerous—wearing sunglasses or squinting in advance can prevent sudden glare. Last week, I saw a rear-end collision caused by slamming the brakes upon exiting the tunnel—maintaining a 150-meter following distance is safest, about the length of three utility poles on the highway. Overtaking inside a tunnel is a major taboo; even in dual lanes, you must patiently queue. Remember, if danger arises, don’t swerve abruptly. Pull over to the right, and place the warning triangle 100 meters behind the car—farther than a basketball court!

What are the methods to deal with excessive carbon monoxide in car exhaust?

Clean the three-way catalytic converter. Once this component is clogged or too dirty, it will lose its ability to convert carbon monoxide. Check the dashboard for any engine warning lights. If the air-fuel ratio of the engine cannot stabilize, incomplete combustion may occur.

What is the simplest way to reset a car's ECU?

Drive for a while to allow the car to reach normal operating temperature, then park and turn off the engine, shutting down all electrical devices in the car. Open the car's hood, locate the battery, and disconnect the battery's power cables. Wait for 10 minutes before reconnecting, then turn on the power without starting the engine and activate the car's electrical devices, waiting for 30 seconds. Remove the key, and the reset is successful.

What is the voltage of the ABS sensor connector?

The voltage of the ABS sensor connector is 5V to 8V, with an output voltage of 650mV to 850mV. During actual measurement, due to the fault protection function of the electronic stability control module, the voltage cannot be sustained after unplugging the ABS sensor connector, so voltage data cannot be used as a judgment criterion. The ABS sensor is an important component of the ABS system. ABS can maintain the directional stability of the vehicle during braking while driving, shorten the braking time and distance, and effectively prevent wheel lock-up and uncontrolled skidding during emergency braking, thereby enhancing the vehicle's controllability and making driving safer.
