2020 Jeep Grand Cherokee 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. For information on the rear wiper/ washer, refer to “Rear Window Wiper/Washer” in this section.

Multifunction Lever

Rotate the end of the lever to one of the first four detent posi- tions for intermittent settings, the fifth detent for low wiper operation and the sixth detent for high wiper operation.

Windshield Wiper Operation

 

 

Use one of the four intermittent wiper settings when weather conditions make a single wiping cycle, with a variable delay between cycles, desirable. At driving speeds above 10 mph (16 km/h), the delay can be regulated from a maximum of approximately 18 seconds between cycles (first detent), to a cycle every one second (fourth detent).

the lever is released, and then resume the intermittent interval previously selected.

Intermittent Wiper Operation

NOTE:

If the vehicle is moving less than 10 mph (16 km/h), delay times will be doubled.

To use the washer, push on the end of the lever (toward the steering wheel) and hold while spray is desired. If the lever is pushed while in the intermittent setting, the wipers will turn on and operate for several wipe cycles after the end of

Windshield Washer Operation

If the end of the lever is pushed while the wipers are in the off position, the wipers will operate for several wipe cycles, then turn off.

NOTE:

As a protective measure, the pump will stop if the switch is held for more than 20 seconds. Once the switch is released the pump will resume normal operation.

 

Use the Mist feature when weather conditions make occa- sional usage of the wipers necessary. Rotate the end of the lever downward to the MIST position and release for a single wiping cycle.

NOTE:

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

This feature senses rain or snowfall on the windshield and automatically activates the wipers for the driver. The feature is especially useful for road splash or overspray from the windshield washers of the vehicle ahead. Rotate the end of the multifunction lever to one of four settings to activate this feature.

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

NOTE:

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

Settings one and two can be used if the driver desires less wiper sensitivity. Setting four can be used if the driver desires more sensitivity. Place the wiper switch in the OFF position when not using the system.

NOTE:

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 performance.
The Rain Sensing feature can be turned on and off using the Uconnect System, refer to “Uconnect Settings” in “Multimedia” for further information.

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 ignition 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 igni- tion is ON, and the automatic transmission 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 2

out of the NEUTRAL position.

Remote Start Mode Inhibit — On vehicles equipped with Remote Starting system, Rain Sensing wipers are not oper- ational when the vehicle is in the remote start mode. Once the operator is in the vehicle and has placed the ignition switch in the RUN position, rain sensing wiper operation can resume, if it has been selected, and no other inhibit conditions (mentioned previously) exist.

The rear wiper/washer controls are located on the multi- function lever on the left side of the steering column. The rear wiper/washer is operated by rotating a switch, located at the middle of the lever.

Rear Wiper/Washer Control

 

Rotate the center portion of the lever upward to the first detent for intermittent operation and to the second detent for continuous rear wiper operation.

Rotating the center portion upward once more will activate the washer pump which will continue to operate as long as the switch is held. Upon release of

the switch, the wipers will resume the continuous rear wiper operation. When this rotary control is in the OFF position, rotating it downward will activate the rear washer pump which will continue to operate as long as the switch is held. Once the switch is released it will return to the OFF position and the wipers will cycle several times before returning to the parked position.

NOTE:

As a protective measure, the pump will stop if the switch is held for more than 20 seconds. Once the switch is released the pump will resume normal operation.

If the rear wiper is operating when the ignition is placed in the OFF position, the wiper will automatically return to the “park” position.
