Pedestrian Ahead Indicator
If equipped, this indicator will display amber
when a nearby pedestrian is detected in
front of the vehicle.
SeeFront Pedestrian Braking (FPB) System
0 234.
Traction Off Light
This light comes on briefly when the vehicle
is turned on. If it does not, have the vehicle
serviced by your dealer. If the system is
working normally, the indicator light then
turns off. The traction off light comes on when the
Traction Control System (TCS) has been
turned off. If StabiliTrak/Electronic Stability
Control (ESC) is turned off, TCS is also
turned off. To turn TCS and ESC off and on,
see
Traction Control/Electronic Stability
Control 0213.
If TCS is off, wheel spin is not limited unless
necessary to help protect the driveline from
damage. Adjust driving accordingly.
StabiliTrak OFF Light
This light comes on briefly when the vehicle
is turned on. If the light does not come on,
have the vehicle serviced by your dealer.
If the system is working normally, the
indicator light then turns off.
This light comes on when the StabiliTrak/
Electronic Stability Control (ESC) system is
turned off. If StabiliTrak/ESC is off, the
Traction Control System (TCS) is also off. To
turn ESC off and on, see Traction Control/
Electronic Stability Control 0213. If ESC and TCS are off, the systems do not
assist in controlling the vehicle. Adjust
driving accordingly.
Traction Control System (TCS)/
StabiliTrak Light
This light comes on briefly when the vehicle
is turned on.
If the light does not come on, have the
vehicle serviced by your dealer. If the
system is working normally, the indicator
light turns off.
If the light is on and not flashing, the TCS
and potentially the StabiliTrak/ESC system
are not fully operational and may not assist
in maintaining control. Adjust driving
accordingly. If the condition persists, see
your dealer as soon as possible. A Driver
Information Center (DIC) message may
display.
The light flashes when the TCS and/or the
StabiliTrak/ESC system is actively working.

Engine Coolant Temperature
Warning Light
This light comes on briefly while starting
the vehicle.
If it does not, have the vehicle serviced by
your dealer. If the system is working
normally the indicator light goes off.
Caution
The engine coolant temperature warning
light indicates that the vehicle has
overheated. Driving with this light on can
damage the engine and it may not be
covered by the vehicle warranty. See
Engine Overheating 0271.
The engine coolant temperature warning
light comes on when the engine has
overheated. If this happens, pull over and turn off the
engine as soon as possible. See
Engine
Overheating 0271.
Tire Pressure Light
For vehicles with the Tire Pressure Monitor
System (TPMS), this light comes on briefly
when the engine is started. It provides
information about tire pressures and
the TPMS.
When the Light Is On Steady
This indicates that one or more of the tires
are significantly underinflated.
A Driver Information Center (DIC) tire
pressure message may also display. Stop as
soon as possible, and inflate the tires to the
pressure value shown on the Tire and
Loading Information label. See Tire Pressure
0 294. When the Light Flashes First and Then Is On
Steady
If the light flashes for about a minute and
then stays on, there may be a problem with
the TPMS. If the problem is not corrected,
the light will come on at every ignition
cycle. See
Tire Pressure Monitor Operation
0 297.
Engine Oil Pressure Light
Oil pressure can vary with engine speed,
outside temperature, and oil viscosity.
On some models, the oil pump will vary
engine oil pressure according to engine
needs. Oil pressure may change quickly as
the engine speed or load varies. This is
normal. If the oil pressure warning light or
Driver Information Center (DIC) message
indicates oil pressure outside the normal
operating range, check the vehicle's oil as
soon as possible.
Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered

Bluetooth (Overview)
The Bluetooth-capable system can interact
with many mobile devices, allowing:
.Placement and receipt of calls in a
hands-free mode.
.Sharing of the device’s address book or
contact list with the vehicle.
To minimize driver distraction, before
driving, and with the vehicle parked:
.Become familiar with the features of the
mobile device. Organize the phone book
and contact lists clearly and delete
duplicate or rarely used entries.
If possible, program speed dial or other
shortcuts.
.Review the controls and operation of the
infotainment system.
.Pair mobile device(s) to the vehicle. The
system may not work with all mobile
devices. See “Pairing”later in this section.
Vehicles with a Bluetooth system can use a
Bluetooth-capable mobile device with a
Hands-Free Profile to make and receive
phone calls. The infotainment system and
voice recognition are used to control the
system. The system can be used while the
ignition is on or in ACC/ACCESSORY. The
range of the Bluetooth system can be up to
9.1 m (30 ft). Not all mobile devices support
all functions and not all mobile devices work
with the Bluetooth system. See
my.chevrolet.com for more information
about compatible mobile devices.
Controls
Use the controls on the center stack and the
steering wheel to operate the Bluetooth
system.
Steering Wheel Controls
g: Press to answer incoming calls and start
voice recognition on your connected
Bluetooth mobile device.
i: Press to end a call, decline a call,
or cancel an operation. Press to mute or

on a call.
Infotainment System Controls
For information about how to navigate the
menu system using the infotainment
controls, see Using the System 0131.
Audio System
When using the Bluetooth mobile device
system, sound comes through the vehicle's
front audio system speakers and overrides
the audio system. The volume level while on
a mobile device call can be adjusted by
pressing the steering wheel controls or the
volume control on the center stack. The
adjusted volume level remains in memory
for later calls. The volume cannot be
lowered beyond a certain level.
Bluetooth (Pairing and Using a
Phone)
