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.
f:Pull the windshield wiper
lever toward you to spray
windshield washer fluid and
activate the wipers. The
wipers will continue until the
lever is released or the
maximum wash time is
reached. When the windshield
wiper lever is released,
additional wipes may occur
depending on how long the
windshield washer had been
activated. See Washer Fluid
0 393 for information on filling
the windshield washer fluid
reservoir.
Compass
The vehicle has a compass
display on the Driver
Information Center (DIC). The
compass receives its heading
and other information from
the Global Positioning
System (GPS) antenna,
StabiliTrak/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
0 207.
Power Outlets
The accessory power outlets
can be used to plug in
electrical equipment, such as a
cell phone or MP3 player.
The vehicle has two accessory
power outlets:
.Inside the center console
storage area.
.On the rear of the center
floor console.
Lift the cover to access the
accessory power outlet.
Certain electrical accessories
may not be compatible with
the accessory power outlet
and could overload a vehicle
circuit breaker or adapter
fuse. If overloaded, the circuit
breaker will reset after all
devices are disconnected or if

166 Infotainment System
SiriusXM Satellite Radio
Service
If equipped, SiriusXM Satellite
Radio Service provides digital
radio reception. Tall buildings
or hills can interfere with
satellite radio signals, causing
the sound to fade in and out.
In addition, traveling or
standing under heavy foliage,
bridges, garages, or tunnels
may cause loss of the
SiriusXM signal for a period of
time. Some cellular services
may interfere with SXM
reception causing loss of
signal.
Mobile Device Usage
Mobile device usage, such as
making or receiving calls,
charging, or just having the
mobile device on may cause
static interference in the radio.
Unplug the mobile device or
turn it off if this happens.
Multi-Band Antenna
The multi-band roof antenna
may be used for radio,
navigation, and other
communication systems,
depending on the equipped
options. To ensure clear
reception, keep the antenna
clear of obstructions, such as
snow and ice. If the vehicle has
a sunroof, and it is open, or a
roof loaded with cargo,
reception may be affected.
Audio Players
Avoiding Untrusted
Media Devices
When using media devices
such as USB and mobile
devices, consider the source.
Untrusted media devices could
contain files that affect
system operation or
performance and should be
avoided.
USB Port
Audio stored on a USB device
may be listened to.
Depending on your vehicle, it
may be equipped with two
USB ports in the center
console under the armrest and
another two on the center
stack. These ports are for
data and charging. There may
also be two USB ports at the
rear of the center console and
a USB port on each side of the
third row seats for
charging only.
Caution
To avoid vehicle damage,
unplug all accessories and
disconnect all accessory
cables from the vehicle
when not in use. Accessory
cables left plugged into the
vehicle, unconnected to a
device, could be damaged or
cause an electrical short if
the unconnected end comes(Continued)

If the vehicle has an automatic
transmission, and is not in
P (Park), the ignition will return
to accessory mode and display
a message in the Driver
Information Center (DIC).
When the vehicle is shifted
into P (Park), the ignition
system will turn OFF.

OnStar 503
OnStar Personal
Identification
Number (PIN)
A PIN is needed to access
some OnStar services. The
PIN will need to be changed
the first time when speaking
with an Advisor. To change the
OnStar PIN, contact an
OnStar Advisor by pressing
Q
or calling 1-888-4ONSTAR.
Warranty
OnStar equipment may be
warranted as part of the
vehicle warranty.
Languages
The vehicle can be
programmed to respond in
multiple languages. Press
Q
and ask for an Advisor.
Advisors are available in
English, Spanish, and French.
Available languages may vary
by country.
Potential Issues
OnStar cannot perform
Remote Door Unlock or Stolen
Vehicle Assistance after the
vehicle has been off
continuously for an extended
period of time without an
ignition cycle. To find out the
duration of time that applies
for the vehicle, contact an
OnStar Advisor by pressing
Q
or calling 1-888-4ONSTAR.
If the vehicle has not been
started for an extended period
of time, OnStar can contact
Roadside Assistance or a
locksmith to help gain access
to the vehicle.
Global Positioning
System (GPS)
.Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;
around airports; in tunnels
and underpasses; or in an
area with very dense trees.
If GPS signals are not
available, the OnStar system
should still operate to callOnStar. However, OnStar
could have difficulty
identifying the exact
location.
.In emergency situations,
OnStar can use the last
stored GPS location to send
to emergency responders.
A temporary loss of GPS can
cause loss of the ability to
send a Turn-by-Turn
Navigation route. The Advisor
may give a verbal route or may
ask for a call back after the
vehicle is driven into an
open area.
Cellular and GPS
Antennas
Cellular reception is required
for OnStar to send remote
signals to the vehicle. Do not
place items over or near the
antenna to prevent blocking
cellular and GPS signal
reception.
