Mazda CX-9 Owners Manual: Windshield Wipers and Washer

Mazda CX-9 Owners Manual / When Driving / Switches and Controls / Windshield Wipers and Washer

The ignition must be switched ON to use the wipers.


Use only windshield washer fluid or plain water in the reservoir: Using radiator antifreeze as washer fluid is dangerous. If sprayed on the windshield, it will dirty the windshield, affect your visibility, and could result in an accident.

Only use windshield washer fluid mixed with anti-freeze protection in freezing weather conditions: Using windshield washer fluid without anti-freeze protection in freezing weather conditions is dangerous as it could freeze on the windshield and block your vision which could cause an accident. In addition, make sure the windshield is sufficiently warmed using the defroster before spraying the washer fluid.

NOTE If the windshield wipers are operated under cold weather conditions or during snowfall, they could stop due to accumulated snow on the windshield. If the windshield wipers stop due to accumulated snow on the windshield, park the vehicle in a safe place, turn the wiper switch off, and then remove the accumulated snow. If the wiper switch is turned to another position other than OFF, the wipers will operate. If the wipers do not operate even though the wiper switch is turned to a position other than OFF, consult an Authorized Mazda Dealer as soon as possible.

Switches and Controls

Auto-wiper control

When the wiper lever is in the position, the rain sensor senses the amount of rainfall on the windshield and turns the wipers on or off automatically (off―intermittent―low speed―high speed).

The sensitivity of the rain sensor can be adjusted by turning the switch on the wiper lever.

From the center position (normal), rotate the switch upward for higher sensitivity (faster response) or rotate it downward for less sensitivity (slower response).

Switches and Controls


  • Do not shade the rain sensor by adhering a sticker or a label on the windshield.

    Otherwise the rain sensor will not operate correctly.

  • When the wiper lever is in the position and the ignition is switched ON, the wipers may move automatically in the following cases:
    • If the windshield above the rain sensor is touched or wiped with a cloth.
    • If the windshield is struck with a hand or other object from either outside or inside the vehicle.

Keep hands and scrapers clear of the windshield when the wiper lever is in the position and the ignition is switched ON as fingers could be pinched or the wipers and wiper blades damaged when the wipers activate automatically.

If you are going to clean the windshield, be sure the wipers are turned off completely (when it is most likely that the engine is left running) this is particularly important when clearing ice and snow.


  • Switching the auto-wiper lever from the OFF to the AUTO position while driving activates the windshield wipers once, after which they operate according to the rainfall amount.
  • The auto-wiper control may not operate when the rain sensor temperature is about -10 ºC (14 ºF) or lower, or about 85 ºC (185 ºF) or higher.
  • If the windshield is coated with water repellent, the rain sensor may not be able to sense the amount of rainfall correctly and the auto-wiper control may not operate properly.
  • If dirt or foreign matter (such as ice or matter containing salt water) adheres to the windshield above the rain sensor, or if the windshield is iced, it could cause the wipers to move automatically.

    However, if the wipers cannot remove this ice, dirt or foreign matter, the auto-wiper control will stop operation.

    In this case, set the wiper lever to the low speed position or high speed position for manual operation, or remove the ice, dirt or foreign matter by hand to restore the auto-wiper operation.

  • If the auto-wiper lever is left in the AUTO position, the wipers could operate automatically from the effect of strong light sources, electromagnetic waves, or infrared light because the rain sensor uses an optical sensor. It is recommended that the auto-wiper lever be switched to the OFF position other than when driving the vehicle under rainy conditions.
  • If the headlight switch and the windshield wiper switch are in AUTO, and the wipers are operated at low or high speed by the auto wiper control for several seconds, bad weather conditions are determined and the headlights may be turned on.
  • The auto-wiper control functions can be turned off.

Windshield Washer

Pull the lever toward you and hold it to spray washer fluid.

Switches and Controls

NOTE If the windshield washer is turned on when the windshield wipers are not operating, the windshield wipers operate a few times.

If the washer does not work, inspect the fluid level. If the fluid level is normal, consult an Authorized Mazda Dealer.
