= : Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The defogger only works when the
ignition is on. The defogger turns off
if the ignition is off or in ACC/
ACCESSORY.
The rear window defogger can be
set to automatic operation. See
“ Climate and Air Quality ” under
Vehicle Personalization 0 114 .
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. At higher speeds, the
rear window defogger may stay on
continuously.
If equipped with heated outside
mirrors, they turn on when the rear
window defogger button is on and help to clear fog or frost from the
surface of the mirrors. See Heated
Mirrors 0 34 .
CautionDo 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.

system may run when the vehicle is
started remotely. The system uses
the driver ’ s previous settings to heat
or cool the inside of the vehicle. The
rear defog may come on during
remote start based on cold ambient
conditions. The rear defog indicator
light does not come on during a
remote start. If equipped with front
heated seats, they may come on
during a remote start. The heated
seat indicator lights do not come
on during a remote start.

Air Vents Adjustable Air Vents 1. Slider Knob
2. Thumbwheel
Use the slider knobs (1) on the air
vents to change the direction of the
airflow.
Use the thumbwheels (2) near the
air vents to control the amount of
airflow or to shut off the airflow.
Fixed Air Vents
Additional air vents are under the
windshield, near the side windows,
and in the foot wells.
Operation Tips
.
Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
can 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.

Driving and Operating 145Warning (Continued).
Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats..
Do not leave an
unsecured child restraint
in the vehicle..
Secure loose items in the
vehicle..
Do not leave a seat
folded down unless
needed. Starting and
Operating New Vehicle Break-In CautionThe 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 ignition switch has four different
positions.

Vehicle Care 213(2) Tire Width :
The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio :
A two-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item 3 of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(4) Construction Code :
A letter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter :
Diameter of
the wheel in inches.
(6) Service Description :
These
characters represent the load
index and speed rating of the tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Tire Terminology and
Definitions Air Pressure :
The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight :
The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.
Aspect Ratio :
The relationship
of a tire's height to its width. Belt :
A rubber coated layer of
cords between the plies and the
tread. Cords may be made from
steel or other reinforcing
materials.
Bead :
The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire :
A pneumatic tire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure :
The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. See Tire Pressure
0 216 .
Curb Weight :
The weight of a
motor vehicle with standard and
optional equipment including the
