be used for service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may be
required for emission inspection purposes.
The switch stays in this position when the
engine is running. The transmission is also
unlocked in this position.
If the key is left in ON/RUN with the engine
off, the battery could drain and the vehicle
may not start.
3 (START) :This is the position that starts
the engine. When the engine starts, release
the key. The ignition returns to ON/RUN for
driving.
Starting the Engine
If the vehicle has a diesel engine, see the
Duramax diesel supplement.
To place the transmission in the
proper gear:
Move the shift lever to P (Park) or
N (Neutral). The engine will not start in any
other position. To restart the engine when
the vehicle is already moving, use
N (Neutral) only.
Caution
If you add electrical parts or accessories,
you could change the way the engine
operates. Any resulting damage would
not be covered by the vehicle warranty.
See Add-On Electrical Equipment 0171.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could
damage the transmission. Shift to P (Park)
only when the vehicle is stopped.
Caution
If the steering wheel is turned until it
reaches the end of its travel, and is held
in that position while starting the vehicle,
damage may occur to the hydraulic
power steering system and there may be
loss of power steering assist.
Starting Procedure 1. With your foot off the accelerator pedal, turn the ignition key to START. When
the engine starts, let go of the key. The
idle speed will go down as your engine gets warm. Do not race the engine
immediately after starting it. Operate
the engine and transmission gently to
allow the oil to warm up and lubricate
all moving parts.
When the low fuel warning light is on
and the FUEL LEVEL LOW message is
displayed in the Driver Information
Center (DIC), the Computer-Controlled
Cranking System is disabled to prevent
possible vehicle component damage.
When this happens, hold the ignition
switch in the START position to continue
engine cranking.
Caution
Cranking the engine for long periods of
time, by returning the ignition to the
START position immediately after
cranking has ended, can overheat and
damage the cranking motor, and drain
the battery. Wait at least 15 seconds
between each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try

142 Driving and Operating
Driving with the parking brake applied will
cause a warning chime to sound and a
Driver Information Center (DIC) message
may display. Release the parking brake or
stop the vehicle.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking to
activate the Antilock Brake System (ABS) if
the brake pedal is not pushed hard enough
to activate ABS normally. Minor noise, brake
pedal pulsation, and/or pedal movement
during this time may occur. Continue to
apply the brake pedal as the driving
situation dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when(Continued)
Warning (Continued)
driving may result in injury, death,
or vehicle damage. SeeDefensive Driving
0 121.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) temporarily prevents the
vehicle from rolling in an unintended
direction during the transition from brake
pedal release to accelerator pedal apply. The
brakes release when the accelerator pedal is
applied or automatically release after a few
seconds. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle.
HSA is available when the vehicle is facing
uphill in a forward gear, or when facing
downhill in R (Reverse). The vehicle must
come to a complete stop on a grade for HSA
to activate.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control System
(TCS) and StabiliTrak/Electronic Stability
Control (ESC), an electronic stability control
system. These systems help limit wheel spin
and assist the driver in maintaining control,
especially on slippery road conditions.
TCS activates if it senses any of the drive
wheels are spinning or beginning to lose
traction. When this happens, TCS applies the
brakes to the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually
traveling. StabiliTrak/ESC selectively applies
braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping
the vehicle on the intended path. Trailer
Sway Control (TSC) is also on automatically
when the vehicle is started. See Trailer Sway
Control (TSC) 0170.

Displayed images may be farther or closer
than they appear. The area displayed is
limited and objects that are close to either
corner of the bumper or under the bumper
do not display.
A warning triangle may appear on the
infotainment display to show that RPA or
Rear Cross Traffic Alert (RCTA) has detected
an object. This triangle changes from amber
to red and increases in size the closer the
object.
{Warning
The camera(s) do not display children,
pedestrians, bicyclists, crossing traffic,
animals, or any other object outside of
the cameras’field of view, below the
bumper, or under the vehicle. Shown
distances may be different from actual
distances. Do not drive or park the
vehicle using only these camera(s).
Always check behind and around the
vehicle before driving. Failure to use
proper care may result in injury, death,
or vehicle damage.
Park Assist
If equipped, the Rear Park Assist (RPA)
system uses sensors on the rear bumper to
assist with parking and avoiding objects
while in R (Reverse).
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects below the bumper or that are
too close or too far from the vehicle. It is
not available at speeds greater than
8 km/h (5 mph). To prevent injury, death,
or vehicle damage, even with Park Assist,
always check the area around the vehicle
and check all mirrors before backing.
How the System Works
RPA comes on automatically when the shift
lever is moved into R (Reverse). A single
beep sounds to indicate the system is
working.
RPA operates only at speeds less than
8 km/h (5 mph). An obstacle detection is indicated by beeps.
The time between beeps gets shorter as the
vehicle approaches the obstacle. Repeated
beeps are heard when the distance is less
than 30 cm (12 in).
To be detected, objects must be at least
25 cm (10 in) off the ground and below rear
door level. Objects must also be within 2.5 m
(8 ft) from the rear bumper. This distance
may be less during warmer or humid
weather.
Turning the System On and Off
The system can be disabled through the
Driver Information Center (DIC). See
“Park
Assist” underDriver Information Center (DIC)
0 82.
RPA defaults to the on setting each time the
vehicle is started.
Turn RPA off when towing a trailer.
When the System Does Not Seem to
Work Properly
The following messages may be displayed
on the DIC:

the driver disables the system or if the
vehicle is driven above 8 km/h (5 mph) in
R (Reverse).
PARK ASST BLOCKED SEE OWNERS
MANUAL : This message can occur under the
following conditions:
.The sensors are not clean. Keep the rear
bumper free of mud, dirt, snow, ice, slush,
and frost. The message may not clear
until frost or ice has melted all around
and inside the sensor.
.A trailer is attached to the vehicle, or a
bicycle or an object hanging out of the
rear door during the current or last drive
cycle. RPA will return to normal operation
after it is determined the object is
removed. This could take a few drive
cycles.
.A tow bar is attached to the vehicle.
Other conditions may affect system
performance, such as vibrations from a
jackhammer or the compression of air
brakes on a very large truck.
Forward Collision Alert (FCA)
System
If equipped, the FCA system may help to
avoid or reduce the harm caused by
front-end crashes. When approaching a
vehicle ahead too quickly, FCA provides a
red flashing alert on the windshield and
rapidly beeps. FCA also lights an amber
visual alert if following another vehicle
much too closely.
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 40 km/h (25 mph).
{Warning
FCA is a warning system and does not
apply the brakes. When approaching a
slower-moving or stopped vehicle ahead
too rapidly, or when following a vehicle
too closely, FCA may not provide a
warning with enough time to help avoid
a crash. It also may not provide any
warning at all. FCA does not warn of
pedestrians, animals, signs, guardrails,
bridges, construction barrels, or other (Continued)
Warning (Continued)
objects. Be ready to take action and
apply the brakes. SeeDefensive Driving
0 121.
FCA can be disabled with the
[button on
the center stack.
Detecting the Vehicle Ahead
FCA warnings will not occur unless the FCA
system detects a vehicle ahead. When a
vehicle is detected, the vehicle ahead
indicator will display green. Vehicles may
not be detected on curves, highway exit
ramps, or hills, due to poor visibility; or if a
vehicle ahead is partially blocked by
pedestrians or other objects. FCA will not
detect another vehicle ahead until it is
completely in the driving lane.

156 Driving and Operating
Driving Characteristics and
Towing Tips
{Warning
You can lose control when towing a
trailer if the correct equipment is not
used or the vehicle is not driven properly.
For example, if the trailer is too heavy or
the trailer brakes are inadequate for the
load, the vehicle may not stop as
expected. You and others could be
seriously injured. The vehicle may also be
damaged, and the repairs would not be
covered by the vehicle warranty. Pull a
trailer only if all the steps in this section
have been followed. Ask your dealer for
advice and information about towing a
trailer with the vehicle.
Driving with a Trailer
Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, durability,
and fuel economy. Successful, safe trailering
takes correct equipment, and it has to be
used properly.The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before pulling a
trailer.
When towing a trailer:
.Become familiar with and follow all state
and local laws that apply to trailer
towing. These requirements vary from
state to state.
.State laws may require the use of
extended side view mirrors. Even if not
required, you should install extended side
view mirrors if your visibility is limited or
restricted while towing.
.Do not tow a trailer during the first
800 km (500 mi) of vehicle use to prevent
damage to the engine, axle, or other
parts.
.It is recommended to perform the first oil
change before heavy towing.
.During the first 800 km (500 mi) of trailer
towing, do not drive over 80 km/h
(50 mph) and do not make starts at full
throttle.
.Vehicles can tow in D (Drive). Tow/Haul
Mode is recommended for heavier trailers.
See
Tow/Haul Mode 0140. If the transmission downshifts too often, a
lower gear may be selected using Manual
Mode. See
Manual Mode 0139.
If equipped, the following driver assistance
features should be turned off when towing
a trailer:
.Adaptive Cruise Control (ACC)
.Super Cruise Control
.Lane Keep Assist (LKA)
.Park Assist
.Automatic Parking Assist (APA)
.Reverse Automatic Braking (RAB)
If equipped, the following driver assistance
features should be turned to alert or off
when towing a trailer:
.Automatic Emergency Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian Braking (FPB)
If equipped with Lane Change Alert (LCA),
the LCA detection zones that extend back
from the side of the vehicle do not move
further back when a trailer is towed. Use
caution while changing lanes when towing a
trailer.
If equipped with Rear Cross Traffic Alert
(RCTA), use caution while backing up when
towing a trailer, as the RCTA detection zones
