Ram 4500 Chassis Cab 2018 Manual Online

The front courtesy overhead console and door courtesy
lights will not turn off if the dimmer control is in the
“Dome ON” position (rotate vertical thumb wheel all the
way to the top detent).
The illuminated entry system will not operate if the
dimmer control is in the “Dome OFF” position (rotate
vertical thumb wheel all the way to the bottom detent).
NOTE:If your vehicle is equipped with illuminated ap-
proach lights under the outside mirrors, they can be turned
off by moving the instrument panel dimmer into the
“Dome Defeat” detent position.
WINDSHIELD WIPERS AND WASHERS
Windshield Wipers
The wipers and washers are operated by a switch in the
multifunction lever. Turn the end of the lever to select the
desired wiper speed. Rotate the end of the lever upward, to the first detent past
the intermittent settings for low-speed wiper operation.
Rotate the end of the lever upward to the second detent
past the intermittent settings for high-speed wiper opera-
tion.
Intermittent Wiper System
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 maxi-
mum 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.
Windshield Washers
To use the windshield washer, push the washer knob,
located on the end of the multifunction lever, inward to the
second detent. Washer fluid will be sprayed and the wiper
will operate for two to three cycles after the washer knob is
released from this position.
If the washer knob is depressed 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.
WARNING!
Sudden loss of visibility through the windshield could
lead to a collision. You might not see other vehicles or
other obstacles. To avoid sudden icing of the wind-
shield during freezing weather, warm the windshield
with the defroster before and during windshield
washer use.
Mist Feature
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 to the first
detent and release. The wipers will cycle one time and
automatically shut off.
NOTE: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.
Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and auto-
matically activates the wipers for the driver. The feature is
especially useful for road splash or overspray from the
80 GETTING TO KNOW YOUR VEHICLE

windshield washers of the vehicle ahead. Rotate the end of
the multifunction lever to one of five settings to activate
this feature.
NOTE:This feature can be programmed through the
Uconnect system. Refer to “Uconnect Settings” in “Multi-
media” for further information.
The sensitivity of the system can be adjusted with the
multifunction lever. Wiper delay position 1 is the least
sensitive, and wiper delay position 5 is the most sensitive.
Position 3 should be used for normal rain conditions.
Positions 1 and 2 can be used if the driver desires less
wiper sensitivity. Positions 4 and 5 can be used if the driver
desires more sensitivity. Place the wiper switch in the O
(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 wind-
shield.
• Use of Rain-X or products containing wax or silicone
may reduce Rain Sensing performance. 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
turned ON, the Rain Sensing system will not operate
until the wiper switch is moved, vehicle speed is greater
than 0 mph (0 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 transmission is in the NEUTRAL
position, the Rain Sensing system will not operate until
the wiper switch is moved, vehicle speed is greater than
5 mph (8 km/h), or the gear selector is moved out of the
NEUTRAL position.
• Remote Start Mode Inhibit — On vehicles equipped
with Remote Starting system, Rain Sensing wipers are
not operational 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.

NOTE:
•Continuous use of the Recirculation mode may make the inside air stuffy and window fog-
ging may occur. Extended use of this mode is not recommended.
•The use of the Recirculation mode in cold or damp weather could cause windows to fog on
the inside, because of moisture buildup inside the vehicle. Select the outside air position for
maximum defogging.
•Recirculation can be used in all modes except for Defrost.
•The A/C can be deselected manually without disturbing the mode control selection.

Modes Control:Rotate the Mode Control Knob to change the airflow distribution mode. The
airflow distribution mode can be adjusted so air comes from the instrument panel outlets, floor
outlets, defrost outlets and demist outlets. The Mode settings are as follows:
Panel Mode
Panel Mode
Air comes from the outlets in the instrument panel. Each of these outlets can be individually
adjusted to direct the flow of air. The air vanes of the center outlets and outboard outlets can be
moved up and down or side to side to regulate airflow direction. There is a shut off wheel lo-
cated below the air vanes to shut off or adjust the amount of airflow from these outlets.
Bi-Level Mode
Bi-Level Mode
Air comes from the instrument panel outlets and floor outlets. A slight amount of air is directed
through the defrost and side window demister outlets.
NOTE: Bi-Level mode is designed under comfort conditions to provide cooler air out of the
panel outlets and warmer air from the floor outlets.
Floor Mode
Floor Mode
Air comes from the floor outlets. A slight amount of air is directed through the defrost and side
window demister outlets.
Mix Mode
Mix Mode
Air is directed through the floor, defrost, and side window demister outlets. This setting works
best in cold or snowy conditions that require extra heat to the windshield. This setting is good
for maintaining comfort while reducing moisture on the windshield.

mild washing solution, wiping parallel to the heat-
ing elements. Labels can be peeled off after soaking
with warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the win-
dow.
• Keep all objects a safe distance from the window.
