How do I tell if my car has rain-sensing wipers?
Yes. In most modern cars, rain-sensing wipers are indicated by an AUTO or RAIN setting on the wiper stalk and a small sensor window near the top of the windshield. You can confirm by checking the owner's manual or testing the system.
Rain-sensing wipers detect moisture on the windshield and automatically adjust wipe speed so you don’t have to change settings as rain intensifies or lightens. The sensor is typically a small transparent window behind the rear-view mirror, but some newer vehicles rely on a camera-based system integrated with ADAS, which is managed through the instrument cluster or driver display.
Where to look for rain-sensing wipers
Use this quick checklist to identify whether your car includes rain-sensing wipers.
- Wiper stalk with AUTO or RAIN setting: Many cars have a position on the stalk labeled AUTO, RAIN, or a raindrop symbol, often accompanied by a small sensitivity dial.
- Windshield sensor window near the rear-view mirror: Look for a small, clear or tinted window on the windshield behind the mirror where moisture is detected. Some sensors are integrated behind a tinted strip.
- Onboard prompts or manual confirmation: Some vehicles display "Auto" on the instrument cluster when Auto rain sensing is engaged, or the status appears in the vehicle's settings menu.
- Camera-based rain sensing (in some newer models): Certain cars use a forward-facing camera as part of the ADAS suite to detect rain, rather than a dedicated infrared/photodiode sensor.
If you can't locate a sensor or setting, consult the owner's manual, check the window sticker or Monroney label, or contact the dealer to confirm whether rain-sensing wipers are included on your trim level.
How to test rain-sensing wipers
To validate the feature, perform a simple in-car test while parked and with the engine on (as required by your vehicle’s operating procedure).
- Turn the wipers to AUTO (or RAIN) mode on the stalk. If there is a sensitivity control, ensure it is roughly in the middle so the system has room to respond.
- Lightly mist the windshield or use a spray bottle to apply a small amount of water across the glass, avoiding the sensor itself as much as possible though some water will reach it.
- Watch the wipers; they should begin wiping automatically within a few seconds and adjust speed as moisture increases or decreases.
- If there is no response, try increasing the sensitivity with the dial or check whether the feature is disabled in settings or requires a car restart. If still no response, the car may not have rain-sensing wipers or the sensor may be malfunctioning.
Note: Not all cars with automatic wipers use the same interface, and a few designs rely on the windshield camera rather than a dedicated sensor; in those cases, the behavior may differ slightly, and you might see adjustments in response to ambient light or spray.
Variation by model
Some manufacturers place the rain-sensing sensor in slightly different locations or present the Auto mode differently in menus. If in doubt, search for your exact make and model's rain-sensing wipers guidance from the official site or owner's manual.
What to do if your car doesn’t have rain-sensing wipers
If you can’t find any AUTO/Rain mode, the windshield sensor, or manual references, your car likely doesn’t have rain-sensing wipers. You’ll still have manual wipers with intermittent settings. Consider asking a dealer about upgrades or trims that include the feature.
Summary
Key signs to confirm rain-sensing wipers: a stalk setting labeled AUTO or RAIN, a sensor window behind the rearview mirror (or a camera-based sensor in newer models), and confirmation in the owner’s manual or window sticker. You can verify by switching to AUTO and applying a light mist to observe automatic wiper activation and speed adjustments.

Because it's a RAV 4 XLE. This is optional equipment. It has a convenience package but it doesn't have a weather package this window sticker does have it. So limited.
How do you turn on rain-sensing wipers?
To turn on rain-sensing wipers, move the wiper stalk to the AUTO position. The specific position may vary by vehicle, so look for the "AUTO" setting on the stalk or in the infotainment system's settings to enable the feature. You can then typically adjust the sensitivity with a dial or ring on the stalk to control how much rain is needed for the wipers to activate.

Step-by-step instructions
- Locate the wiper stalk: This is usually on the right side of the steering wheel.
- Activate the "AUTO" mode: Push the stalk up to the position marked "AUTO". If you don't see an "AUTO" setting, there might be a different indicator, such as a circle with an "A" or other symbols, so check your owner's manual.
- Adjust the sensitivity: Use the dial or ring on the stalk to change the sensitivity.
- Higher sensitivity: Turn the dial up or towards a plus sign so the wipers activate with even a small amount of moisture.
- Lower sensitivity: Turn the dial down or towards a minus sign so the wipers activate only when there is a significant amount of water.
- Turn off if needed: Before going through an automatic car wash, turn the system off to prevent damage. You may need to push the stalk down to the "off" position or turn it off in the vehicle's settings menu.
How to check rain sensor?
Here are some tips to try you can clean your sensor. Move it to a better location. Change the battery. Check your wiring. Check the box connected to your controller. And replace your quirks with new.
