2021 RAM 1500 Owners Manual - WINDSHIELD WIPERS AND WASHERS



WINDSHIELD WIPERS AND WASHERS

The windshield wiper/washer controls are located on the multifunction lever on the left side of the steering column. The front wipers are operated by rotating a switch, located on the end of the lever.

WINDSHIELD WIPER OPERATION

The intermittent feature of this system was designed for use when weather conditions make a single wiping cycle, with a variable pause between cycles, desirable. For maximum delay between cycles, rotate the control knob upward to the first detent.

The delay interval decreases as you rotate the knob until it enters the low continual speed position. The delay can be regulated from a maximum of about 18 seconds between cycles, to a cycle every one second. The delay intervals will double in duration when the vehicle speed is 10 mph (16 km/h) or less.

To use the windshield washer, push the washer knob, located on the end of the multifunction lever, inward and hold. Washer fluid will be sprayed and the wiper will operate for two to three cycles after the washer knob is released.

If the washer knob pushed while in the delay range, the wiper will operate for several seconds after the washer knob is released. It will then resume the intermittent interval previously selected. If the washer knob is

pushed while in the off position, the wiper will turn on and cycle approximately three times after the wash knob is released.

To prevent freeze-up of your windshield washer system in cold weather, select a solution or mixture that meets or exceeds the temperature range of your climate. This rating information can be found on most washer fluid containers.

When a single wipe to clear off road mist or spray from a passing vehicle is needed, push the washer knob, located on the end of the multifunction lever, inward briefly and release. The wipers will cycle one time and automatically shut off.

The mist feature does not activate the washer pump; therefore, no washer fluid will be sprayed on the windshield. The wash function must be used in order to spray the windshield with washer fluid.

For information on wiper care and replacement, see page 418.

RAIN SENSING WIPERS — IF EQUIPPED

This feature senses rain or snowfall on the windshield and automatically activates the wipers. Rotate the end of the multifunction lever to one of four detent positions to activate this feature.

The sensitivity of the system can be adjusted with the multifunction lever. Wiper delay position one is the least sensitive, and wiper delay detent position four is the most sensitive.

Wiper delay position three should be used for normal rain conditions.

Positions one and two can be used if the driver desires less wiper sensitivity. Position four can be used if the driver desires more sensitivity. Place the wiper switch in the O (off) position when not using the system.

    The Rain Sensing feature will not operate when the wiper switch is in the low or high-speed position.
    The Rain Sensing feature may not function properly when ice, or dried salt water is present on the windshield.
    Use of Rain-X or products containing wax or silicone may reduce Rain Sensing perfor- mance.
    The Rain Sensing feature can be turned on and off using the Uconnect system

page 237.

The Rain Sensing system has protection features for the wiper blades and arms, and will not operate under the following conditions:

    Low Ambient Temperature — When the igni- tion is first placed in the ON position, the Rain Sensing system will not operate until the wiper switch is moved, vehicle speed is greater than 3 mph (5 km/h), or the outside temperature is greater than 32°F (0°C).
    Transmission In NEUTRAL Position — When the ignition is ON, and the automatic transmis- sion is in the NEUTRAL position, the Rain Sensing system will not operate until the wiper switch is moved, vehicle speed is greater than 3 mph (5 km/h), or the gear selector is moved out of the NEUTRAL position.
    Remote Start Mode Inhibit — On vehicles equipped with Remote Start system, Rain Sensing wipers are not operational when the vehicle is in the remote start mode.
