window fogging, it returns to normal
operation. For eAssist vehicles,
there may be shorter and less
frequent Auto Stops when auto
defog is in use.
To turn Auto Defog off or on, see
“Climate and Air Quality”under
Vehicle Personalization 0133.
Ionizer : If equipped with an ionizer,
this feature helps to clean the air
inside the vehicle and remove
contaminants; such as pollen,
odors, and dust. If the climate
control system is on and the ionizer
is enabled, the ionizer status
indicator will be lit on the climate
control display. To turn the ionizer
on or off, see “Climate and Air
Quality” underVehicle
Personalization 0133.
Rear Window Defogger
K:Press to turn the rear window
defogger on or off. An indicator light
on the control comes on to show
that the rear window defogger is on.
The rear window defogger only
works when the engine is running.
It turns off when the ignition is
turned off or in ACC/ACCESSORY. The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality”
under
Vehicle Personalization 0133.
When Auto Rear Defog is selected,
the rear window defogger turns on
automatically when the interior
temperature is cold and the outside
temperature is about 4 °C (40 °F)
and below. The auto rear defogger
turns off automatically after about
10 minutes, or after five minutes if
the outside temperature is not
as cold.
For eAssist vehicles, auto rear
defog will only run during a remote
start and the feature is not available
in the Vehicle Personalization menu.
The upper gridlines on the rear
window are antenna lines and are
not intended to heat when the
defogger is activated.
If the vehicle is equipped with
heated outside mirrors, they turn on
when the rear window defogger
control is on and help to clear fog or
frost from the surface of the mirror.
See Heated Mirrors 045.
Caution
Do not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything
else that is sharp. This may
damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.

Heated and Ventilated Seats 012.
Sensors
The solar sensor on top of the
instrument panel near the
windshield, monitors the solar heat.
Do not cover the solar sensor or the
system will not work properly.
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.
Air Vents
Use the slider knob on the air vent
louvers to change the amount and
direction of the airflow.
To close the outboard air vents,
move the slider knob to the full
outboard position.
To close the center air vents, move
the slide knob to the full inboard
position.
To close the rear passenger air
vents, move the slider knob to the
full inboard position. Operation Tips
.
Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
. Clear snow off the hood to
improve visibility and help
decrease moisture drawn into
the vehicle.
. Keep all outlets open whenever
possible for best system
performance.
. Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
. Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.

New Vehicle Break-In
Caution
The vehicle does not need an
elaborate break-in. But it will
perform better in the long run if
you follow these guidelines:. Do not drive at any one
constant speed, fast or slow,
for the first 805 km (500 mi).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
. Avoid making hard stops for
the first 322 km (200 mi) or
so. During this time the new
brake linings are not yet
broken in. Hard stops with
new linings can mean
premature wear and earlier
replacement. Follow this
(Continued)
Caution (Continued)
breaking-in guideline every
time you get new brake
linings.
Following break-in, engine speed
and load can be gradually
increased.
Ignition Positions
The vehicle has an electronic
keyless ignition with pushbutton
start. If the pushbutton start is not
working, the vehicle may be near a
strong radio antenna signal causing
interference to the Remote Keyless
Entry (RKE) system. See
Remote
Keyless Entry (RKE) System
Operation 028.
To shift out of P (Park), the ignition
must be on and the brake pedal
must be applied.
Stopping the Engine/OFF (No
Indicator Light) : When the vehicle
is stopped, press ENGINE START/
STOP once to turn the vehicle off.
The transmission will shift to
P (Park) automatically.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) 0176.

172 Driving and Operating
Starting the Engine
Place the transmission in P (Park) or
N (Neutral). To restart the engine
when the vehicle is already moving,
use N (Neutral).
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 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.

0 226. To start the vehicle:
1. With the Keyless Access system, the Remote Keyless
Entry (RKE) transmitter must
be in the vehicle. Press
ENGINE START/STOP with the
brake pedal applied. When the
engine begins cranking, let go
of the button. The idle speed
will go down as the engine
warms up. Do not race the
engine immediately after
starting it.
If the RKE transmitter is not in
the vehicle, if there is
interference, or if the RKE
battery is low, a Driver
Information Center (DIC)
message will display. See
Remote Keyless Entry (RKE)
System Operation 028.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
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 pushing the
accelerator pedal all the way to
the floor and hold it there, then
press ENGINE START/STOP
for up to a maximum of
15 seconds. Wait at least
15 seconds between each try,
to allow the cranking motor to
cool down. When the engine
starts, let go of the button and
the accelerator. If the vehicle
starts briefly but then stops
again, do the same thing. This
clears the extra gasoline from
the engine. Do not race the
engine immediately after

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0237. .
Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0231 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center
(DIC) message displays, check the
oil level.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
engine oil level on steep grades
