What functions should be turned on when driving in heavy rain?

When encountering heavy rain, functions such as auto start-stop and auto hold should be turned off. Here are some tips for driving in heavy rain: 1. Proper use of lights: Whether it's day or night, always turn on the low beam and position lights when driving in rain or fog. If the rain is too heavy or visibility is poor due to thick fog, turn on the fog lights. Hazard lights should only be used when parking or during emergency braking to alert vehicles behind. They should not be turned on randomly during normal driving, as this can make it difficult for vehicles behind with poor visibility to discern the lane-changing intentions of the vehicle ahead or to spot vehicles stopped on the road due to various reasons in bad weather. 2. Low speed and high RPM when passing through waterlogged areas: If you need to pass through a waterlogged area, drive in a low gear at a slow speed, maintaining steady throttle. Avoid stopping, shifting gears, or making sharp turns midway. Even if you use neutral gear, keep revving the engine to ensure the exhaust pressure is higher than the water pressure, preventing water from flowing back into the exhaust pipe and damaging the exhaust system. If the water depth exceeds the center of the wheel or the exhaust pipe, it's best not to proceed to avoid engine stalling during passage.

When driving in heavy rain, I immediately turn on the front and rear fog lights, which significantly improves visibility in the rain and makes it easier for others to see my car. Then, I adjust the windshield wipers to high speed or automatic mode to ensure the windshield isn't obstructed by rainwater. Low-beam headlights or automatic headlights must also be turned on to increase illumination. The air conditioning's defogging function is essential; otherwise, the windows will fog up and block visibility. Controlling speed is crucial—rain makes the road slippery and increases braking distance—so I always drive slowly in a low gear, avoiding sharp turns or sudden braking. Additionally, I check the tire tread depth—excessive wear can lead to hydroplaning—and activate the ESP anti-skid function for added stability. Remember these tips, and you can travel safely even in heavy rain.

As a novice driver, I feel a bit nervous during heavy rain, but first, I turn the windshield wipers to the fastest setting to clear the front glass. Then, I turn on the front and rear fog lights and low-beam headlights to improve visibility. The defogging mode of the air conditioning must be activated; otherwise, fogged-up windows can dangerously obscure vision. Controlling speed is crucial—avoid sudden acceleration, drive slower to prevent skidding, and engage the ESP system for assistance. I also noticed that maintaining a longer following distance is essential because rain slows down braking response. Occasionally, I activate the hazard warning lights only in extreme situations, but generally, I use them sparingly. After practicing these steps a few times, I've gotten used to them—safety is no small matter.

Driving in the rain requires extra caution. Let's turn on the rear fog lights to ensure visibility for vehicles behind us, and set the wipers to high speed to keep the windshield clear. Activate the low beam headlights to improve illumination. Don't forget to use the air conditioning's defogging function to prevent fog buildup. Maintain a controlled speed and avoid sudden maneuvers—safety always comes first.

In heavy rain, immediately turn on front and rear fog lights to enhance visibility, and set wipers to high speed to remove rainwater; turn on headlights for illumination, and use the air conditioning defogging mode to prevent condensation. Drive at reduced speed and utilize ESP for anti-skid, check tire wear to avoid hydroplaning; perform regular maintenance on lights and wipers.

Driving in heavy rain poses high risks, so I always turn on the front and rear fog lights to enhance visibility; set the wipers to high speed to clear the windshield; turn on the headlights to ensure road visibility; and activate the air conditioning defogging function to prevent fog interference. Drive at low speeds to control hydroplaning risks; enable the ESP system to enhance stability, and regularly check tire traction; use hazard lights only in emergencies. This combination of features maximizes safety and reduces the likelihood of accidents.
