2007 CHEVROLET CORVETTE coolant temperature

Fuel Range:The range calculates the remaining
distance you can drive without refueling. It is
based on fuel economy and the fuel remaining in
the tank.
Press the fuel button again to display the range,
such as:
RANGE 30 MI or
RANGE 48 km
If the LOW FUEL warning is displayed or if
RANGE is less than 40 miles (64 km), the display
will read RANGE LOW.
The fuel economy data used to determine fuel
range is an average of recent driving conditions.
As your driving conditions change, this data is
gradually updated automatically.
If the vehicle has been idling for a long time, the
range displayed on the DIC could be abnormally
low. The vehicle must be driven 5–10 miles
(8–16 km) to get an accurate reading.

temperature. To avoid added strain on a hot engine,
the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the A/C operation automatically resumes.
You can continue to drive your vehicle. If this
message continues to appear, have the system
repaired by your dealer as soon as possible to
avoid compressor damage.
ICE POSSIBLE
This message displays when the outside air
temperature is cold enough to create icy road
conditions. Adjust your driving accordingly.

If this message displays and the check engine
light comes on, a noticeable reduction in the
vehicle’s performance may occur. If the REDUCED
ENGINE POWER message is displayed, but
there is no reduction in performance, proceed to
your destination. The performance may be reduced
the next time the vehicle is driven.
The vehicle may be driven at a reduced speed
while the REDUCED ENGINE POWER message

TRANSMISSION HOT IDLE ENGINE
This message displays and four chimes sound
if the transmission uid temperature rises above
270°F (132°C) or rises rapidly. The transmission
may shift gears or apply the torque converter
clutch to reduce the uid temperature. Driving
aggressively or driving on long hills can cause the
transmission uid temperature to be higher than
normal. If this message appears, you may continue
to drive at a slower speed. Monitor the transmission
uid temperature and allow it to cool to at least
230°F (110°C). The transmission uid temperature
can be monitored with the gages button on the DIC.
SeeDIC Controls and Displays on page 208and
Automatic Transmission Fluid on page 345. Also
check the engine coolant temperature. If it is also
hot, seeEngine Overheating on page 350.
231

Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years
or 150,000 miles (240 000 km), whichever
occurs rst, if you add only DEX-COOL
®
extended life coolant.
The following explains your cooling system
and how to add coolant when it is low. If you
have a problem with engine overheating,
seeEngine Overheating on page 350.A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would
not be covered by your warranty. Always
use DEX-COOL
®(silicate-free) coolant in
your vehicle.
