Instrument Panel Clusters
Your instrument panel clusters are designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, how much fuel you’re using, and many
other things you’ll need to drive safely and economically.
Your vehicle is equipped with one
of these instrument panel clusters, which includes indicator warning lights and
gages that are explained on the following pages.
Cluster with Gages
2-58

Boost Gage (Option) Head-Up Display (Option)
fXjST
Vehicles equipped with the supercharged engine have
this boost gage that indicates vacuum during light
to
moderate throttle and boost under heavier throttle. The
gage displays the air pressure level in psi going into the
engine’s combustion chamber.
The gage is automatically centered at zero psi every
time the engine is started. Actual vacuum or boost
is
displayed from this zero point. Changes in ambient
pressure, such as driving in mountains
and changing
weather, will slightly change the zero reading.
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it’s dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If you have the optional Head-Up Display (HUD), you
can see some
of the driver information also available on
your instrument panel cluster. The information
may be
displayed in English or metric units and appears as a
reflection on the windshield. The
HUD shows:
0 Speedometer reading
0 Turn signal indicators
0 High-beam indicator symbol
CHECK GAGES message (for low oil pressure, high
coolant temperature, low oil level and low fuel)
Low fuel warning symbol
