Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-12460269) - 2019 - crc - 4/19/18
Instruments and Controls 137
If the ignition is turned off while the
wipers are performing wipes due to
windshield washing or Rainsense,
the wipers continue to run until they
reach the base of the windshield.
Rainsense
With Rainsense, a sensor near the
top center of the windshield detects
the amount of water on the
windshield and controls the
frequency of the windshield wiper.
Keep this area of the windshield
clear of debris to allow for best
system performance.
3 INT : Turn the z FRONT
band on the wiper lever to adjust the
sensitivity when Rainsense is
turned on.
.
Turn the band up for more
sensitivity to moisture.
.
Turn the band down to lower INT
setting for less sensitivity to
moisture.
Move the band out of the
3 INT
position to deactivate Rainsense.
z AUTO : Press to turn
Rainsense on or off. When turned
on and
z FRONT is in one of the
Rainsense wipe sensitivity positions
the wipers can be adjusted for more
or less sensitivity to moisture. When
turned off, the wipers operate as
timed intermittent wipers and can be
adjusted for more or less frequent
wipes.
If
z AUTO is turned on when the
ignition is turned on, or if the ignition
is on and the
z FRONT band is
in one of the sensitivity settings
when
z AUTO is turned on or off,
a message may display indicating if
Rainsense was turned on or off.
If the ignition is on and
z FRONT
is not in one of the sensitivity
settings when
z AUTO is turned
on, a message may display
indicating that the wiper band must
be in one of the sensitivity settings
for Rainsense to operate.
Wiper Arm Assembly Protection
When using an automatic car wash,
move the windshield wiper lever to
OFF. This disables the automatic
Rainsense windshield wipers.
With Rainsense, if the transmission
is in N (Neutral) and the vehicle
speed is very slow, the wipers will
automatically stop at the base of the
windshield.
The wiper operations return to
normal when the transmission is no
longer in N (Neutral) or the vehicle
speed has increased.
