Pontiac 2004 GTO - Manual (Page 123)

Speedometer
The speedometer shows vehicle speed in both miles
per hour (mph) and kilometers per hour (km/h).
Tachometer
The tachometer shows engine speed in revolutions
per minute (rpm).
For automatic transmission vehicle’s, under wide open
throttle acceleration, when the accelerator pedal is
pushed flat to the floor, it is possible that the tachometer
needle may briefly enter the lower end of the
tachometer’s red zone just prior to automatically
upshifting into a higher gear. This is normal during
wide open throttle acceleration and will not harm
the engine.
Notice: If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
Safety Belt Reminder Light
When the key is turned to
ON, the safety belt light
will come on and stay
on for several seconds and
a chime will be sounded
for eight seconds,
then it will flash
continuously until the
driver’s belt is buckled.
If the driver’s belt is already buckled, the light will not
come on.
