Voltmeter Gage; One-To-Four Shift Light; (Manual Transmission) - Chevrolet 2008 Corvette Owner's Manual

Voltmeter Gage

The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read BATTERY VOLTAGE
LOW when your vehicle is at 10 volts or below. Have it
checked right away. Driving with the voltmeter reading at
10 volts or below could drain your battery and disable
your vehicle.
3-38
The voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of
the charging system.

One-to-Four Shift Light

(Manual Transmission)

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 if you prefer.
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),
•
the vehicle is going 15 to 19 mph (24 to 31 km/h) and
•
the vehicle 21 percent throttle or less.
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
