What do the letters on the wipers mean?

[VanNova]

There are several English letters on the car wipers, which are OFF, INT, LO, and HI. They respectively mean the front wiper stops working, automatic intermittent operation, continuous operation, and continuous high-speed operation. The detailed introduction is as follows: 1. OFF: OFF means the front wiper stops working; 2. INT: INT means automatic intermittent operation. This gear needs to be operated manually and is suitable for light rain and light snow; 3. LO: LO means continuous operation. This gear also needs manual operation, but it is suitable for heavy rain and heavy snow; 4. HI: HI means continuous high-speed operation, which also requires manual operation and is suitable for heavy rainstorms.

I was also confused by the letters on the wiper when I first picked up my car, but later I specifically studied these symbols. MIST is the single wipe mode—press it once for just one wipe, perfect for when mud suddenly splashes onto the windshield. INT stands for intermittent wiping, where the wiper moves every few seconds, which is especially handy in light drizzles. LO is the continuous low-speed mode, and I usually choose this for moderate rain. HI is the high-speed mode, ideal for heavy downpours to ensure clear visibility. OFF, of course, means the wiper is turned off. Nowadays, new cars often come with an AUTO label featuring rain-sensing functionality, which automatically adjusts the frequency based on the size of raindrops. Remember not to dry-wipe for too long when washing the car, as it can easily damage the rubber blades.

When I first started driving, I could never remember these symbols, but now I can operate them with my eyes closed. MIST is the manual single wipe function, perfect for sudden situations like bird droppings. INT works intermittently based on the frequency you set, and I usually switch to this setting during light rain. Both LO and HI are continuous operation modes, but low speed is suitable for daily light rain, while high speed is essential during heavy rain. Make sure to turn OFF in sunny weather to avoid unnecessary motor strain. Some cars also have a fan-shaped icon for the washer function—press lightly to spray washer fluid and press hard to activate the wipers. It's best to check the wiper blades for cracks every six months, as aged rubber can affect wiping performance.

These letters actually represent the wiper operation modes. MIST is the momentary function, where the wiper moves once per press. INT stands for intermittent wiping, allowing adjustment of the wiping interval. LO indicates low-speed continuous wiping, while HI is the high-speed mode for heavy rain. OFF means the wipers are turned off. When driving in the rain, remember the activation sequence: use INT for light rain, switch to LO as rain intensifies, and shift to HI during downpours. Be careful not to confuse the wiper control knob with the turn signal lever, as the former is usually located on the right side of the steering wheel. Regularly cleaning leaves and debris from the wiper blades can extend their lifespan.
