2006 CHEVROLET CORVETTE coolant temperature

Stopping Your Engine
If your vehicle has an automatic transmission, move the
shift lever to PARK (P) and press the ACC button
located on the instrument panel. If the shifter is not in
PARK (P), the vehicle will go into accessory mode
and the DIC will display SHIFT TO PARK. Once the
shifter is moved to PARK (P), the vehicle will turn off.
If your vehicle has a manual transmission, move the shift
lever to REVERSE (R).
If the keyless access transmitter is not detected inside
the vehicle when it is turned to off, the DIC will
display NO FOB – OFF OR RUN?.
SeeDIC Warnings and Messages on page 3-53for
more information.
Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater.
In very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also have
an internal thermostat in the plug end of the cord. This
will prevent operation of the engine coolant heater
when the temperature is at or above 0°F (−18°C) as
noted on the cord.
2-24

To Use The Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver’s side
of the engine compartment, in front of the coolant
surge tank.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

One to Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to turn off
this feature. This helps you get the best possible fuel
economy.
After shifting to FOURTH (4), you may downshift to a
lower gear.
Notice:Forcing the shift lever into any gear except
FOURTH (4) when the 1 TO 4 SHIFT light comes
on may damage the transmission. Shift only from
FIRST (1) to FOURTH (4) when the light comes on.
This light will come on when:
The engine coolant temperature is higher than
169°F (76°C),
you are going 15 to 19 mph (24 to 31 km/h) and
you are 21 percent throttle or less.
Downshifting (Manual Transmission)
Do not downshift into the gear shown below at a speed
greater than shown in the table:
FIRST (1) 50 mph (80 km/h)
SECOND (2) 74 mph (119 km/h)
THIRD (3) 101 mph (163 km/h)
FOURTH (4) 130 mph (209 km/h)
Notice:If you skip more than one gear when you
downshift, or if you race the engine when you
release the clutch pedal while downshifting, you
could damage the engine, clutch, driveshaft or the
transmission. Do not skip gears or race the
engine when downshifting.
The six-speed transmission has a spring that centers
the shift lever near THIRD (3) and FOURTH (4).
This spring helps you know which gear you are in when
you are shifting. Be careful when shifting from
FIRST (1) to SECOND (2) or downshifting from
SIXTH (6) to FIFTH (5). The spring will try to pull the
shift lever toward FOURTH (4) and THIRD (3).
Make sure you move the lever into SECOND (2) or
FIFTH (5). If you let the shift lever move in the direction
of the pulling, you may end up shifting from FIRST (1)
to FOURTH (4) or from SIXTH (6) to THIRD (3).

Manual Paddle Shift Gear Indicator (If Equipped)
These lights 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 LS2 engine
and 7,000 RPM for the LS7 engine.

Audio Functions, Street Mode Only
Navigation, Only with Navigation Radio, Street
Mode OnlyThere are three HUD modes that you can choose to view
in the HUD display. By pressing the MODE button, you
can scroll through these modes in the following order:
Street Mode supports
audio and navigation
functions with your choice
of tachometer settings.
Track Mode 1 supports the
G-Force gage and minor
gages with a circular
tachometer.
3-21

Track Mode 2 supports
G-Force gages and minor
gages with a linear
tachometer.
When you have chosen the desired HUD display,
release the MODE button.
Within each mode, the display, can be further
customized by pressing the PAGE button. Pressing this
button in each mode will turn off and on the following:
Street Mode — No tachometer, circular tachometer
and linear tachometer.
Track Modes 1 and 2 — No minor gage, coolant
temperature, transmission oil temperature, engine
oil temperature and engine oil pressure.
While in Track Mode 1 or 2, the maximum G value
achieved during the current ignition cycle can be
displayed by pressing and holding the PAGE button.
The maximum G display will be shown until the
PAGE button is released. The maximum G value
display will be identical to the normal G value
display, except the maximum G gage digits (X.XX G)
and corresponding G gage bar will overwrite the
current G value.If your vehicle is equipped
with a navigation radio,
many of the turn-by-turn
navigation features
will also be displayed on
the HUD if you are in
Street Mode.
See the navigation system manual for additional
information.
Be sure to continue scanning your displays, controls
and driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see 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.

you are going 15 to 19 mph (24 to 31 km/h) and
you are 21 percent throttle or less.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
This light should come on when you start the engine.
If it does not come on then, have it xed so it will
be ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-33
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.

When the system is working, you will see the ACTIVE
HANDLING message displayed in the DIC. You may also
feel or hear the system working. This is normal.
If the driver turns off the Active Handling System by
pressing the button on the console for ve seconds, the
Active Handling System light will come on, a chime
will sound, and the TRACTION SYSTEM AND ACTIVE
HANDLING – OFF message will be displayed in the
DIC. The Traction Control System will also be turned off.
SeeDIC Warnings and Messages on page 3-53for
more information.
If the Active Handling System and the Traction Control
System are off, pressing the console button momentarily
will turn both systems on. The DIC will display the
TRACTION SYSTEM AND ACTIVE HANDLING – ON
message, the instrument cluster light will be off, and
a chime will sound. SeeDIC Warnings and Messages
on page 3-53for more information.Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the shaded area, your
engine is too hot.
This means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
