The wipers are operated by a rotary switch in the
wiper control dial, which is on the end of the turn sig-
nal lever. There are five intermittent settings, marked
on the dial by lines of increasing length, and two
steady speed settings: LO and HI.
Turn the wipers on by rotating the control dial coun-
terclockwise. Rotate the control dial further to in-
crease the speed of the wipers through the various
intermittent settings, then to LO and HI.
Rotate the control dial clockwise to slow the wipers
down. Rotate the control dial clockwise as far as it
will go to turn the wipers off.
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/Trailer Connection
Controls
Air Suspension Dump 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 may be
used to aid in connecting or disconnecting from a
trailer. See
Fig. 5.15 . When the switch is set to
LOWER, the air-suspension dump valve deflates the
air springs to lower the rear of the vehicle. In the
AUTO position, the automatic ride-control valves op-
erate for normal driving.
NOTICE
Never exhaust air from the suspension while
driving. When the air is exhausted, the suspen-
sion will not absorb road shocks, and compo-
nents may be damaged.
A red LED in the switch is illuminated when the sus-
pension is deflated.
ECAS Remote Control Unit (ECAS
only)
Some vehicles equipped with Electronically Con-
trolled Air Suspension (ECAS) have a remote control
unit to lower and raise the rear suspension. See
Table 5.2 for keys and functions.
If the suspension is outside normal ride height
(amber lamp on), the ECAS system will automatically
return the suspension to normal ride height when
vehicle speed reaches or exceeds a set speed (usu-
ally set to 5 mph).
