Caution
Holding a cigarette lighter in while
it is heating does not let the
lighter back away from the
heating element when it is hot.
Damage from overheating can
occur to the lighter or heating
element, or a fuse could be
blown. Do not hold a cigarette
lighter in while it is heating.
Ashtrays
If equipped with a removable
ashtray, it can be placed into the
front floor console cupholder. Open
the cover to use.
Caution
If papers, pins, or other
flammable items are put in the
ashtray, hot cigarettes or other
smoking materials could ignite
them and possibly damage the
vehicle. Never put flammable
items in the ashtray.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.

Exterior Lighting
Exterior Lamp Controls
The exterior lamp control is on the
instrument panel to the left of the
steering wheel.
There are four positions:
O: Briefly turn the control to this
position to turn the automatic
headlamps and Daytime Running
Lamps (DRL) off or back on.
For vehicles first sold in Canada,
the off position only works for
vehicles that are shifted into the
P (Park) position. AUTO :
Automatically turns the
exterior lamps on and off,
depending on outside lighting.
;: Turns on the parking lamps
including all lamps, except the
headlamps.
2: Turns on the headlamps
together with the parking lamps and
instrument panel lights.
If the headlamps are turned on
while the vehicle is on, the
headlamps turn off automatically
10 minutes after the ignition is
turned off. If the headlamps are
turned on while the vehicle is off,
the headlamps will continue to stay
on. To prevent the battery from
being drained, turn the control to the
Oposition.
A warning chime sounds if the driver
door is opened while the ignition
switch is off and the headlamps
are on.
To change the headlamps from low
beam to high beam, pull the turn
signal lever all the way toward you.
Then release it.

1 (ACC/ACCESSORY) :This is the
position in which you can operate
things like the radio and the
windshield wipers when the engine
is off.
2 (ON/RUN) : This position can be
used to operate the electrical
accessories and to display some
instrument cluster warning and
indicator lights. This position can
also 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.
If you leave the key in the ACC/
ACCESSORY or ON/RUN position
with the engine off, the battery could
be drained. You may not be able to
start the vehicle if the battery is
allowed to drain for an extended
period of time.
3 (START) : This is the position that
starts the engine. When the engine
starts, release the key. The ignition
switch returns to ON/RUN for
driving. A warning tone will sound when the
driver door is opened, the ignition is
in ACC/ACCESSORY or LOCK/OFF
and the key is in the ignition.
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
0 212.
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

196 Driving and Operating
{Warning
SBZA does not alert the driver to
vehicles rapidly approaching
outside of the side blind zones,
pedestrians, bicyclists,
or animals. It may not provide
alerts when changing lanes under
all driving conditions. Failure to
use proper care when changing
lanes may result in injury, death,
or vehicle damage. Before
making a lane change, always
check mirrors, glance over your
shoulder, and use the turn
signals.SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, or 3.5 m
(11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft)
and 2 m (6 ft) off the ground. This
zone starts at approximately the
middle of the vehicle and goes back
8 m (26 ft).
How the System Works
The SBZA symbol lights up in the
side mirrors when the system
detects a moving vehicle in the next
lane over that is in the side blind
zone. This indicates it may be unsafe to change lanes. Before
making a lane change, check the
SBZA display, check mirrors, glance
over your shoulder, and use the turn
signals.
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror SBZA displays will
briefly come on to indicate the
system is operating. When the
vehicle is in a forward gear, the left
or right side mirror display will light
up if a moving vehicle is detected in
that blind zone. If the turn signal is
activated in the same direction of a
detected vehicle, this display will
flash as an extra warning not to
change lanes.
