Tachometer
The tachometer shows your engine speed in revolutions
per minute (rpm).
Notice: Do not operate the engine with the
tachometer in the red area, or engine damage may
occur.
Safety Belt Reminder Light
When the key is turned to ON 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.
If the driver's belt is already buckled, neither the chime
nor the light will come on.
The safety belt light will
also come on and stay
on for several seconds,
then it will flash for
several more.
