100 Instruments and Controls
The rear window wiper/washer will not
operate if the liftgate is open or ajar. If the
liftgate is opened while the rear wiper is on,
the wiper returns to the parked position and
stops.
See“Rear Camera Washer” later in this
section.
Rear Wiper Arm Assembly Protection
When using an automatic car wash, move
the rear wiper control to OFF to disable the
rear wiper. In some vehicles, if the
transmission is in N (Neutral) and the
vehicle speed is very slow, the rear wiper
will automatically park under the rear
spoiler.
The wiper operations return to normal when
the transmission is no longer in N (Neutral)
or the vehicle speed has increased.
Auto Wipe in Reverse Gear
If the rear wiper control is off, the rear
wiper will automatically operate
continuously when the transmission is in
R (Reverse), and the front windshield wiper
is performing low or high speed wipes.
If the rear wiper control is off, the
transmission is in R (Reverse), and the front windshield wiper is performing INT wipes,
then the rear wiper automatically performs
INT wipes.
This feature can be turned on or off. See
“Auto Wipe in Reverse Gear”
under
Settings > Vehicle > Comfort and
Convenience > Auto Wipe in Reverse Gear.
The windshield washer reservoir is used for
the windshield, rear window, and rear mirror
camera, if equipped. See Rear Camera Mirror
0 30. Check the fluid level in the reservoir if
either washer is not working. See Washer
Fluid 0323.
Rear Camera Washer
If equipped, turn the windshield wiper band
fully upward or downward to spray washer
fluid on the rear camera. The wipers will
clear the rear camera and either stop or return to your preset speed. For more
washer cycles, turn and hold the band. See
Rear Camera Mirror
030.
Compass
The vehicle may have a compass display on
the Driver Information Center (DIC). The
compass receives its heading and other
information from the Global Positioning
System (GPS) antenna, Electronic Stability
Control (ESC), and vehicle speed information.
The compass system is designed to operate
for a certain number of miles or degrees of
turn before needing a signal from the GPS
satellites. When the compass display shows
CAL, drive the vehicle for a short distance in
an open area where it can receive a GPS
signal. The compass system will
automatically determine when a GPS signal
is restored and provide a heading again.
Clock
Set the time and date using the
infotainment system. See "Time/Date" under
Settings 0167.

178 Climate Controls
If equipped with heated outside mirrors,
press
fto turn them on or off. SeeHeated
Mirrors 029.
Caution
Using a razor blade or sharp object to
clear the inside rear window can damage
the rear window defogger. Repairs would
not be covered by the vehicle warranty.
Do not clear the inside rear window with
sharp objects.
Remote Start Climate Control Operation : If
Equipped: When the vehicle is started
remotely, the climate control system, rear
window defog— and if equipped, heated
or ventilated seats or a heated steering
wheel— may run based on climate
conditions. When this occurs, the window
defog indicator will not light up as it does
normally. See Remote Vehicle Start 014,
Heated and Ventilated Front Seats 044, and
Heated Steering Wheel 097.
Sensors
The solar sensor, on top of the instrument
panel near the windshield, monitors the
solar heat.
The climate control system uses the sensor
information to adjust the temperature, fan
speed, recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise the
automatic climate control system may not
work properly. Afterblow Feature
If equipped, under certain conditions, the
fan may stay on or may turn on and off
several times after you turn off and lock the
vehicle. This is normal.
Rear Climate Control System
The rear climate control system is located
on the rear of the center console storage.
The rear climate settings can be adjusted
with this system.

Driving and Operating 235
Do not install objects on top of the vehicle
that overhang and obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on a roof rack
system. SeeRoof Rack System 094.
Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.
Cleaning the Sensing System
The camera sensor on the windshield behind
the rearview mirror, and the sensors on the
front of the vehicle can become blocked by
snow, ice, dirt, mud, or debris. This area
needs to be cleaned for ACC to operate
properly.
If ACC will not operate, regular cruise control
may be available. See “Switching Between
ACC and Regular Cruise Control” previously
in this section. Always consider driving
conditions before using either cruise control
system.
For cleaning instructions, see “Washing the
Vehicle” underExterior Care 0378.Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on Super Cruise-enabled roads
that are separated from opposing traffic.
Super Cruise can also steer to perform a
lane change under certain conditions on
Super Cruise-enabled roads.
A lane change can be initiated by the driver
using the turn signal lever.
The Super Cruise System may initiate a lane
change maneuver in following scenarios:
.to pass slower traffic
.when the current lane is ending ahead
.to return to the initial lane
See “Super Cruise Lane Change” later in this
section and Turn and Lane-Change Signals
0 136.
{Warning
Super Cruise can only assist to maintain
lane position, or steer to change lanes,
when driving on compatible roads. You
must supervise the driving task and
monitor the road conditions. You may
(Continued)
Warning (Continued)
need to respond to traffic events by
steering, braking, or accelerating. See
Defensive Driving.
Super Cruise is:
.Not a self-driving system
.Not a crash avoidance or warning
system
.Not a substitute for proper supervision
of the driving task.
Super Cruise uses the following to detect
the current lane position and lane markings
ahead on compatible roads under certain
conditions:
.Cameras
.Global Positioning System (GPS) sensing
.A high-precision map
.GPS-enhancement data downloaded
through OnStar
Super Cruise works with Adaptive Cruise
Control (ACC), which controls acceleration
and braking while Super Cruise is enabled
and operating. Review and understand both
