Interior Lamps
Instrument Panel/Brightness Control
You can brighten or dim your instrument cluster lights
by turning the headlamp knob. Turn the knob clockwise
to brighten the instrument cluster lights and displays.
Turn the knob clockwise all the way to turn on the
interior courtesy lamps. Turn the knob counterclockwise
to dim the instrument cluster lights and displays and to
turn off the courtesy lamps.
Illuminated Entry (Option)
When you press the UNLOCK button on the optional
remote keyless entry transmitter, the lamps inside your
vehicle will go on. These lamps will go off after about
25 seconds, or when you start your engine. Pressing the
LOCK button on your remote keyless entry transmitter
will turn the lights immediately off.
If a door is left ajar, your interior lamps will turn off
after 10 minutes to save your battery.
Delayed Illumination
When you open the door to enter your vehicle, the
interior lamps will come on. When you close the door
with the ignition off, the interior lamps will stay on for
25 seconds or until the ignition is turned on. Please note
that locking the doors with the power door lock switch
will override the delayed illumination feature and the
lamps will turn off right away.
Theater Dimming
This feature allows for a three to five-second fade out of
the courtesy lamps instead of immediate turn off.
Exit Lighting
With this feature, the interior lamps will come on for 25
seconds after you remove the key from the ignition. This
will give you time to find the door pull handle or lock
switches as you exit the vehicle.

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

2-77 Boost Gage (Option)
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.
Head-Up Display (Option)
CAUTION:
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:

Speedometer reading

Turn signal indicators

High
-beam indicator symbol

CHECK GAGES message (for low oil pressure, high
coolant temperature, low oil level and low fuel)

Low fuel warning symbol
