Engine Coolant Heater - Chevrolet 2007 Corvette Owner's Manual

Notice: Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle's
warranty.
Stopping Your Engine
If your vehicle has an automatic transmission,
move the shift lever to PARK (P) and press the
Acc. (Off/Accessory) button located on the
instrument panel. If the shift lever is not in
PARK (P), the engine shuts off and the vehicle
goes into the Accessory Mode. The DIC displays
SHIFT TO PARK. Once the shifter is moved to
PARK (P), the vehicle turns off. If your vehicle
has a manual transmission, it is recommended
that you move the shift lever to REVERSE (R) and
set the parking brake after you turn off the engine
by pressing the Acc. (Off/Accessory) button.
If the keyless access transmitter is not detected
inside the vehicle when it is turned to off, the DIC
displays NO FOB – OFF OR RUN?.
See DIC Warnings and Messages on page 214 for
more information.

Engine Coolant Heater

Your vehicle may have 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.
