Toyota bZ4X Owner's Manual: Windshield Wipers and Washer

The windshield wipers provide both automatic and manual operation, ensuring clear visibility in various weather conditions. The system allows you to switch between modes by operating the control lever, giving you flexibility based on driving circumstances.

• In manual mode, you can activate the wipers at different speeds to match the intensity of rain or debris on the windshield.
• In automatic mode, sensors detect moisture levels and adjust wiper speed accordingly, reducing the need for manual adjustments.
• The washer function sprays cleaning fluid onto the windshield to remove dust, dirt, or obstructions, improving visibility.

Avoid using the wipers when the windshield is dry, as doing so may cause scratches or damage to the glass surface. Instead, activate the washer function first to apply cleaning fluid before engaging the wipers.

Keeping your windshield wipers in good condition is essential for safe driving. Regular maintenance, including checking the wiper blades for wear and ensuring the washer fluid reservoir is filled, contributes to optimal performance. Advanced sensor-based wiper systems, like those found in one innovative Toyota model, enhance driver convenience by automatically adjusting to weather changes, allowing for a seamless and safe driving experience.

Operating the wiper lever

Operating the lever operates the wipers or washer as follows: When "AUTO" is selected, the wipers will operate automatically when the sensor detects falling rain. The system automatically adjusts wiper timing in accordance with rain volume and vehicle speed.

1.   *1 or *2 Off
2. Rain-sensing operation
3. *1 or *2 Low speed operation
4. *1 or *2 High speed operation
5. *1 or *2 Temporary operation

*1:For the U.S.A.

*2:For Canada

When "AUTO" is selected, the sensor sensitivity can be adjusted by turning the switch ring.

6. Increases the sensitivity
7. Decreases the sensitivity

8. Washer/wiper dual operation

Pulling the lever operates the wipers and washer.

The wipers will automatically operate a couple of times after the washer squirts.

(After operating several times, the wipers operate once more time after a short delay to prevent dripping.

However, the dripping prevention does not operate while the vehicle is moving.)

9. * Washer operation Pushing the lever operates the washer and cleans the camera for the Digital Rear-view Mirror.

The windshield wipers and washer can be operated when

The power switch is in ON.

When the windshield wipers are set to low-speed mode, their operation adjusts based on vehicle movement. If the vehicle is stationary, the wipers automatically switch to intermittent operation to conserve energy and reduce unnecessary movement. However, if the sensor sensitivity is set to its highest level, the mode remains unchanged, ensuring continuous wiping for maximum visibility.

The raindrop sensor detects the amount of rain on the windshield using an optical system. This intelligent feature enhances driving safety by automatically adjusting the wiper speed based on rainfall intensity.

• The sensor may experience interference in certain conditions, such as when direct sunlight-especially during sunrise or sunset-strikes the windshield intermittently.
• Objects on the windshield, like insects or debris, may disrupt proper sensor functionality, potentially affecting wiper performance.

By integrating advanced optical detection, the raindrop sensor offers a responsive and efficient solution for maintaining a clear windshield under various weather conditions. Ensuring that the sensor area remains clean and unobstructed will help maintain its accuracy, contributing to a safer and more comfortable driving experience.

The wiper and washer system is designed for versatile operation-offering both automatic and manual control-to maintain a clear windshield under various weather conditions. When the power switch is ON and you select the AUTO mode, the system momentarily activates the wipers to confirm that the automatic mode is engaged. Similarly, if you increase the wiper sensitivity, you may notice a single wipe cycle as an immediate response to the adjustment.

• If the wiper switch is turned to AUTO while the power is ON, the wipers will operate once to indicate that the mode is active.
• When increasing the wiper sensitivity, a single wiper cycle may occur to show that the new sensitivity setting is in effect.
• If the temperature of the raindrop sensor exceeds 185ºF (85ºC) or falls below 5ºF (-15ºC), the automatic operation might not occur. In this case, choose a mode other than AUTO to maintain functionality.

Additionally, if no windshield washer fluid sprays from the nozzles (despite a full fluid reservoir), inspect the nozzles for any blockage that might be hindering proper spray.

The system also supports voice control commands for added convenience. Through voice commands, you can:

• Activate a single operation of the windshield wipers.
• Engage the windshield cleaning washer (this function is available only when the vehicle is stationary).

Caution Regarding AUTO Mode Operation

In AUTO mode, the wipers may operate unexpectedly if the sensor is touched or if the windshield vibrates. To avoid accidental operation, ensure that your fingers or any objects do not interfere with the sensor.

Caution Regarding Washer Fluid in Cold Weather

In cold conditions, resist using the washer fluid until the windshield is warm. Applying washer fluid in freezing temperatures may cause it to freeze on the glass, significantly reducing visibility and potentially leading to hazardous driving situations.

Washer Fluid Tank and Nozzle Maintenance

If the washer fluid tank is empty, avoid operating the switch continuously to prevent overheating of the washer pump. Moreover, if a nozzle becomes blocked, do not attempt to clear it with tools like pins or other sharp objects as this might damage the nozzle-contact your authorized service center immediately.

12-Volt Battery Conservation

To conserve your vehicle’s 12-volt battery when the EV system is off, avoid leaving the wipers on longer than necessary.

This robust and intelligent system is engineered to provide optimal visibility and safe driving under varying environmental conditions. Its features-from adaptive wiper sensitivity and voice control functions to proactive maintenance prompts-all contribute to a superior driving experience, enhancing both convenience and energy efficiency. Advanced technologies like these, as exemplified by one distinguished Toyota model, set the stage for modern automotive innovation and reliability.
