Boost Gage
If your vehicle is equipped with this gage, it is located
on the steering column.
This gage indicates vacuum during light to moderate
throttle and boost under heavier throttle.
The gage displays the air pressure level going into the
engine’s combustion chamber.
The gage is automatically centered at zero every time
the ignition is turned to RUN. Actual vacuum or boost is
displayed from this zero point.
The boost gage is also equipped with three pairs of
lights that are located on each side of the gage. These
lights are used to indicate three different engine rpm
levels. The default setting for the lower pair of lights is
4,400 rpm, the middle pair of lights is 5,600 rpm, and
the top pair of lights is 6,200 rpm. These settings can be
adjusted by turning the stem behind each light. To
have the light come on at a higher rpm level, turn the
stem counterclockwise. To have the light come on
at a lower rpm level, turn the stem clockwise. Each turn
adjusts the settings by 100 rpm. To restore the default
settings, press and hold any stem for three seconds.
The lights will flash three times.
To turn the lights off or on, press and release any stem.
Message Center
The message center is located in the instrument
panel cluster. It gives you important safety and
maintenance facts.
If there are several messages, each message will be
shown for a few seconds and will continue to repeat until
cleared. To clear a message, press the trip/reset
button while the message you want to clear is being
displayed.
Many messages will also cause a chime to sound, to
alert you to the message.
