Interior Mirror
Vehicles with a manual rearview mirror can be adjusted
by holding the mirror in the center to move it for a
clearer view behind the vehicle. To avoid glare from the
headlamps behind you, push the tab, located at the
base of the mirror, toward you for daytime use and pull
it for nighttime use.
Vehicles with an automatic dimming rearview mirror will
automatically reduce the glare from the headlamps of
the vehicle behind. The dimming feature comes on and
the indicator light illuminates each time the ignition is
turned to start.
SeeAutomatic Dimming Rearview Mirror on page 3‑41.

steering column.
1. Pull the lever down to adjust the steering wheel.
2. Move the steering wheel up or down into a comfortable position.
3. Pull the lever up to lock the steering wheel in place.

Object Detection Systems
Rear Vision Camera (RVC)
The vehicle may have a Rear Vision Camera system.
Read this entire section before using it.
{WARNING:
The Rear Vision Camera (RVC) system does not
replace driver vision. RVC does not:
.Detect objects that are outside the camera's
field of view, below the bumper, or underneath
the vehicle.
.Detect children, pedestrians, bicyclists,
or pets.
Do not back the vehicle by only looking at the
RVC screen, or use the screen during longer,
higher speed backing maneuvers or where there
could be cross-traffic. Your judged distances using
the screen will differ from actual distances. (Continued)
WARNING: (Continued)
So if you do not use proper care before backing
up, you could hit a vehicle, child, pedestrian,
bicyclist, or pet, resulting in vehicle damage,
injury, or death. Even though the vehicle has
the RVC system, always check carefully before
backing up by checking behind and around the
vehicle.
The rear vision camera system is designed to help
the driver when backing up by displaying a view of
the area behind the vehicle. When the key is in the
ON/RUN position and the driver shifts the vehicle into
R (Reverse), the video image automatically appears on
the inside rear view mirror. Once the driver shifts out of
R (Reverse), the video image automatically disappears
from the inside rear view mirror.

Turning the Rear Vision Camera System
Off or On
To turn off the rear vision camera system, press and
hold
z, located on the inside rearview mirror, until the
left indicator light turns off. The rear vision camera
display is now disabled.
To turn the rear vision camera system on again, press
and hold
zuntil the left indicator light illuminates. The
rear vision camera system display is now enabled and
the display will appear in the mirror normally.
Rear Vision Camera Location
The camera is located in the rear of the vehicle.
The area displayed by the camera is limited and does
not display objects that are close to either corner or
under the bumper. The area displayed can vary
depending on vehicle orientation or road conditions.
The distance of the image that appears on the screen
differs from the actual distance.
The following illustration shows the field of view that the
camera provides.
3-45

The rear vision camera system display in the rearview
mirror may turn off or not appear as expected due to
one of the following conditions. If this occurs the left
indicator light on the mirror will flash.
.A slow flash may indicate a loss of video signal,
or no video signal present during the reverse cycle.
.A fast flash may indicate that the display has
been on for the maximum allowable time during
a reverse cycle, or the display has reached an
Over Temperature limit.
The fast flash conditions are used to protect the
video device from high temperature conditions.
Once conditions return to normal the device will
reset and the green indicator will stop flashing.
During any of these fault conditions, the display will be
blank and the indicator will continue to flash as long as
the vehicle is in R (Reverse) or until the conditions
return to normal.
Pressing and holding
zwhen the left indicator light is
flashing will turn off the video display along with the left
indicator light.

Racing or Other Competitive Driving
See your warranty book before using your vehicle for
racing or other competitive driving. After reviewing your
warranty book, please see the GM Performance Parts
website or catalog and contact the race sanctioning
bodies, for example Sports Car Club of America
(SCCA) or Grand American, for parts and equipment
required for racing or other competitive driving.
Notice:If you use your vehicle for competitive
driving, the engine may use more oil than it would
with normal use. Low oil levels can damage the
engine. Be sure to check the oil level often during
competitive driving and keep the level at or near the
upper mark that shows the proper operating range
on the engine oil dipstick. For information on how to
add oil, see Engine Oil on page 6‑19.
Driving at Night
Night driving is more dangerous than day driving
because some drivers are likely to be impaired —by
alcohol or drugs, with night vision problems, or by
fatigue. Night driving tips include:
.Drive defensively.
.Do not drink and drive.
.Reduce headlamp glare by adjusting the inside
rearview mirror.
.Slow down and keep more space between you and
other vehicles because headlamps can only light
up so much road ahead.
.Watch for animals.
.When tired, pull off the road.
.Do not wear sunglasses.
.Avoid staring directly into approaching headlamps.
.Keep the windshield and all glass on your vehicle
clean
—inside and out.
.Keep your eyes moving, especially during turns or
curves.
No one can see as well at night as in the daytime.
But, as we get older, these differences increase.
A 50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.
