see the OnStar Owner's Guide
or visit www.onstar.com (U.S.) or
www.onstar.ca (Canada), contact OnStar at 1-888-4-ONSTAR
(1‐888‐466‐7827) or TTY
1‐877‐248‐2080, or push
the
Qbutton to speak with an
OnStar Advisor 24 hours a day,
seven days a week.
For a full description of OnStar
services and system limitations,
see the OnStar Owner's Guide in
the glove box.
OnStar service is subject to the
OnStar Terms and Conditions
included in the OnStar Glove
Box Kit.
OnStar service requires wireless
communication networks and the
Global Positioning System (GPS)
satellite network. Not all OnStar
services are available everywhere
or on all vehicles at all times.
OnStar service cannot work unless
your vehicle is in a place where
OnStar has an agreement with
a wireless service provider for
service in that area, and the
wireless service provider has
coverage, network capacity, reception, and technology
compatible with OnStar service.
Service involving location
information about your vehicle
cannot work unless GPS signals
are available, unobstructed,
and compatible with the OnStar
hardware. The vehicle must have
a working electrical system and
adequate 12‐volt battery power for
the OnStar equipment to operate.
OnStar service may not work if the
OnStar equipment is not properly
installed or you have not maintained
it even if your vehicle is in good
working order and in compliance
with all government regulations.
If you try to add, connect, or modify
any equipment or software in your
vehicle, OnStar service may not
work. Other problems beyond
OnStar's control may prevent
service to you, such as hills,
tall buildings, tunnels, weather,
electrical system design and
architecture of your vehicle, damage
to important parts of your vehicle
in a crash, or wireless phone
network congestion or jamming.

Remote Keyless
Entry (RKE) System
SeeRadio Frequency
Statement on page 13‑28 for
information regarding Part 15
of the Federal Communications
Commission (FCC) rules and
Industry Canada Standards
RSS-210/220/310.
If there is a decrease in the RKE
operating range:
.Check the distance.
The transmitter may be
too far from the vehicle.
.Check the location. Other
vehicles or objects may be
blocking the signal.
.Check the transmitter's battery.
See “Battery Replacement” later
in this section.
.If the transmitter is still not
working correctly, see your
dealer or a qualified technician
for service.
Remote Keyless Entry
(RKE) System Operation
The RKE transmitter functions will
work up to 60 m (195 ft) away from
the vehicle.
Keep in mind that other conditions,
such as those previously stated,
can impact the performance of the
transmitter.
K(Unlock): Press once to unlock
the driver door. Press a second time
within five seconds to unlock all
doors. The hazard warning lamps will
flash twice each time the button
is pressed and the anti-theft
alarm system will be disarmed.
See
Anti-theft Alarm System on
page 2‑13.
Q(Lock): Press to lock all doors.
The hazard warning lamps will flash
once and the anti-theft alarm system
will be armed. See Anti-theft Alarm
System on page 2‑13.
If the driver door is open when
Qis
pressed, all doors lock and then
the driver door will unlock if the
Unlocked Door Anti Lock Out
feature is enabled through
the vehicle personalization.
See “Unlocked Door Anti Lock
Out Feature” underVehicle
Personalization on page 5‑53 for
more information. This may vary
based on vehicle personalization.

5-16 Instruments and Controls
Compass
The vehicle has a compass display
in the instrument cluster above
the speedometer. The compass
receives its heading and other
information from the Global
Positioning System (GPS) antenna
and vehicle speed information.
The compass system has automatic
calibration and zone adjustment
features.
Avoid covering the GPS antenna
for long periods of time with objects
that may interfere with the antenna's
ability to receive a satellite signal.
SeeMulti-Band Antenna on
page 7‑18 for the location of the
vehicle's antenna. 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. The compass
system will automatically determine
when a GPS signal is restored and
provide a heading.
Battery Gauge
(High Voltage)
This indicator displays the high
voltage battery charge level.
When this indicator is displayed
in the foreground, the vehicle
is operating in Electric Mode.
The number next to the indicator
displays an estimate of how far
the vehicle can be driven while
in this mode.
See Electric Mode on page 9‑25.
Fuel Gauge
This indicator displays the fuel
level. When this indicator is in the
foreground, the vehicle is operating
in Extended Range Mode.
The number next to the indicator
displays an estimate of how far
the vehicle can be driven while
in this mode.
SeeExtended Range Mode on
page 9‑25.

5-34 Instruments and Controls
Delayed Departure Time:The
vehicle estimates the charging start
time considering the programmed departure time for the current day
of the week. Charging begins at the
start time and is complete by the
departure time only if sufficient time
is allowed after the charge cord is
plugged in. The vehicle uses an
internal clock for programmable
charging, not the clock in the
center stack.
Delayed Rate and Departure
Time:
The vehicle estimates the
charging start time based on the
utility rate schedule, utility rate
preference, and the programmed
departure time for the current day of
the week. The vehicle will charge
during the least expensive rate
periods to achieve a full battery
charge by the departure time.
Electrical rate information from the
utility company for the charging
location is required for this mode.

Vehicle Care 10-19
Cooling System
(High Voltage Battery)
During vehicle operation and
also during charging, the high
voltage battery cells in the
vehicle are kept within a normal
operating temperature range.
If the temperature rises above this
temperature, the battery cooling
system turns on the air conditioning
compressor and cools the coolant
until the correct temperature is
reached. If the temperature falls
below this temperature, a high
voltage heater, located in the
battery, heats the coolant until the
correct temperature is reached.
What to Use
The high voltage battery coolant
reservoir in the vehicle is filled
with a 50/50 mixture of DEX-COOL
engine coolant and deionized water.
If using this mixture, nothing else
needs to be added.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery
coolant reservoir is located
on the passenger side of the
engine compartment. SeeEngine
Compartment Overview on
page 10‑10 for more information
on location.Check to see if coolant is visible
in the high voltage battery coolant
reservoir. If coolant is visible but the
coolant level is below the cold fill
line, there could be a leak in the
cooling system.
The high voltage battery coolant
should only be serviced by a
qualified technician.
