Saturn 2005 L-Series - Manual (Page 117)

Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
The maximum rpm is limited in PARK (P) and
NEUTRAL (N) to 4000 rpm by the vehicle’s computer.
This is to prevent engine damage.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime
will come on for several seconds to remind people to
fasten their safety belts, unless the driver’s safety belt
is already buckled.
The safety belt light will
also come on and stay
on for several seconds,
then it will flash for
several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
