Daimler Freightliner Cascadia 2021, Driver Manual

The first intermittent setting of 6 seconds is program-
mable from 1 to 25 seconds. To program the interval,
rotate the switch from the first intermittent position to
the OFF position, wait for the desired interval be-
tween wipes to lapse (between 1 and 25 seconds),
and then move the switch back to the first intermit-
tent position. If the switch is kept in the OFF position
for more than 50 seconds, the interval changes back
to the default of 6 seconds.
The second intermittent setting has an interval of 1
second, and is not programmable.
NOTE: Some vehicles may have a feature that
automatically turns on the headlights if the wind-
shield wipers are on and the vehicle is moving
faster than 10 mph (16 km/h). At speeds be-
tween 10 and 40 mph (16 to 64 km/h), cycling
the headlight switch will turn the headlights off.
Wipers and the Rain/Light Sensor
If the vehicle is equipped with a rain/light sensor (see
Fig. 4.23 ) and the wiper switch is in set to an inter-
mittent setting, the wipers will start when the sensor
detects rain or snow.
If the vehicle is moving faster than 40 mph (64 km/h)
the wiper speed will automatically increase and de-
crease, dependent upon how much moisture builds
up on the windshield between wipes.
If the wiper switch is set to a continuous speed (low
or high), input from the rain/light sensor is ignored.
The behavior of the wipers based on the rain/light
sensor input is independent of the headlamp switch
position.
NOTE: If a rain/light sensor is installed in the
MPC2 bracket, the lens area of the camera will
appear shiny when viewed through the wind-
shield because of the silicone gel between the
lens and the windshield. If no rain/light sensor is
installed, the plastic plug placed in the bracket
will appear as a flat black circle.
A vehicle equipped with automatic headlights
and an A option on the headlight switch (see
Fig. 4.2 ) should be equipped with a rain/light
sensor.
Windshield Washers
The windshield washer button is located at the end
of the turn signal lever. Momentarily press the wind-
shield washer button to initiate a single wipe without
activating the washer pump. The wipers will swipe
one full cycle and return to the inactive position.
To operate the windshield washers, press and hold
the button in. After a short delay, the washer will
pump windshield washer fluid onto the windshield for
as long as the washer button is pressed. The wind-
shield wipers will turn on at low speed while the
washer button is pressed. After the button is re-
leased, the wipers will continue to operate for one to
several wipe cycles, depending on how long the
wash button was pressed initially.
Suspension Controls
Air Suspension Height Control Switch
NOTICE
Do not operate the vehicle over uneven ground
such as ramps, speed bumps, curbs, etc. with
the air springs deflated. Doing this may lead to
air bag separation from the piston, preventing the
suspension air springs from re-inflating.
The air suspension height control switch is used to
adjust the vehicle height to aid in coupling or uncou-
pling from a trailer. See
Fig. 4.24 . Setting the switch
to LOWER deflates the air springs to lower the rear
of the vehicle. In the NORMAL position, the air
springs inflate to raise the rear of the vehicle to nor-
mal ride height.
