2009 CHEVROLET CORVETTE Owners Manual

If the vehicle is started in a dark garage, the automatic
headlamp system come on immediately. Once the
vehicle leaves the garage, it takes about one minute for
the automatic headlamp system to change to DRL if
it is light outside. During that delay, the instrument panel
cluster may not be as bright as usual. Make sure the
instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-18.
You can idle the vehicle with the lamps off, even
when it is dark outside.
After starting the vehicle, turn the exterior lamp control
band on the multifunction lever to off and then
release it. The lamps will remain off until the control
band is turned to off again.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, the
lamps will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position, or
A delay time that you select has elapsed.See “Personal Options” underDIC Vehicle
Personalization on page 3-71to select the delay time
that you want. You can also select no delay time.
If you turn off the ignition with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
The regular headlamp system should be turned on
when needed.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off as soon as
the ignition is turned off or Retained Accessory Power
(RAP) is active. This protects against draining the
battery in case you have accidentally left the headlamps
or parking lamps on. The battery saver does not work
if the headlamps are turned on after the ignition switch is
turned to off.
If you need to leave the lamps on, use the exterior lamp
control to turn the lamps back on.

Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in your
eld of view, it may take you more time to see
things you need to see when it is dark outside.
Be sure to keep the HUD image dim and placed
low in your eld of view.
For vehicles with the Head-Up Display (HUD), you can
see some of the driver information that appears on
the instrument panel cluster.
The information may be displayed in English or metric
units and appears as an image focused out toward
the front of the vehicle. The HUD consists of the
following information:
Speedometer
Turn Signal Indicators
High-Beam Indicator Symbol
Tachometer
Manual Paddle Shift Gear Indicator (If Equipped)
These displays on the HUD are for use when
using the manual paddle shift controls to shift the
transmission. See “Manual Paddle Shift” in
Automatic Transmission Operation on page 2-26.
Shift Light
This light is used for performance driving to indicate
that the vehicle’s best performance level has been
reached to shift the transmission into the next
higher gear. An arrow pointing up will light up on
the display just prior to reaching the engine fuel
cut-off mode. This cut-off is about 6,500 RPM for
the LS3 engine, 6,600 RPM for the LS9 & ZR1
engines and 7,000 RPM for the LS7 engine.

Be sure to continue scanning the displays, controls and
driving environment just as you would in a vehicle
without HUD. If you never look at the instrument panel
cluster, you may miss something important, such as
a warning light. Under important warning conditions,
the CHECK GAGES warning will illuminate in the HUD.
View your Driver Information Center (DIC) for more
information.The HUD controls are
located to the left of the
steering wheel.
To adjust the HUD so it can be seen properly, do the
following:
1. Start the engine and press the HUD dimmer control
all the way up by pressing the (+) button.
The brightness of the HUD image is determined by
the light conditions in the direction the vehicle is
facing and where you have the HUD dimmer
control set. If you are facing a dark object or a
heavily shaded area, the HUD may anticipate that
you are entering a dark area and may begin to dim.
It is possible for sunlight to enter the HUD making
it difficult to see the image. The display will return to
normal when the sunlight is no longer entering
the HUD.

2. Adjust the seat to a comfortable driving position.
If your seat position changes, the HUD may need
to be re-adjusted.
3. Press the up or down arrows to center the HUD
image in your view.
The HUD image can only be adjusted up and down,
not side-to-side.
4. Press the dimmer control downward until the
HUD image is no brighter than necessary.
To turn HUD off, press and hold the (–) button until
the HUD display turns off.
If the sun comes out or it becomes cloudy, the HUD
brightness may need to be adjusted again using
the dimmer control. Polarized sunglasses could make
the HUD image harder to see.
The HUD information can be displayed in one of
six languages including English, Spanish, French,
German, Italian or Japanese. The speedometer can be
displayed in either English or Metric units.
To change the language and unit selections, see
“OPTION” underDIC Operation and Displays on
page 3-49.Clean the inside of the windshield as needed to remove
any dirt or lm that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry
it. Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.
If the ignition is on and the HUD image cannot be seen,
check to see if:
Something is covering the HUD unit.
The HUD dimmer control is adjusted properly.
The HUD image is adjusted to the proper height.
Ambient light is low, in the direction the vehicle
is facing.
A fuse is blown. SeeFuses and Circuit Breakers
on page 5-103.
Keep in mind that the windshield is part of the HUD
system. SeeWindshield Replacement on page 5-60.

console storage compartment, on the forward left side.
To use the outlet, remove the tethered cap. When not
using it, always cover the outlet with the protective cap.
Notice:Leaving electrical equipment plugged in
for an extended period of time while the vehicle is

the outlets. Always unplug electrical equipment
when not in use and do not plug in equipment that
exceeds the maximum 20 ampere rating.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer/retailer for additional
information on accessory power outlets.Notice:Adding any electrical equipment to the
