the instrument panel cluster to adjust the brightness.
HUD:This button is used to adjust the vertical position
of the HUD display.
To adjust the HUD so you can see it properly, do the
following:
1. Adjust the seat to a comfortable driving position. If
you change your seat position later, you may have
to re-adjust your HUD.2. Start your engine and press the top or bottom
of the HUD button to center the HUD image in
your view.
The HUD image can only be adjusted up and down,
not side-to-side.
3. Press the DIMMER button until the DIC reads HUD
DIMMING. Then use the brightness button to adjust
the desired intensity.
The brightness of the HUD image is determined by the
light conditions in the direction your vehicle is facing
and where you have the HUD set. If you are facing a
dark object or a heavily shaded area, your HUD
may anticipate that you are entering a dark area and
may begin to dim.
To turn off the HUD, press the brightness button down
until the image disappears.
Polarized sunglasses could make the HUD image
harder to see.
As light shines out from the HUD, it is possible for light
to shine back in. In rare occurrences, when the sun
is at a speci®c angle and position, the sun's rays can
shine back into the HUD. When this occurs, the display
device within the HUD will be temporarily illuminated.
The event will end when the vehicle's angle to the
sun changes.

Instrument Panel Cluster
Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance how the
vehicle is running. You will know how fast you are going, about how much fuel you have left and many other things
you will need to know to drive safely and economically. The instrument panel cluster indicator warning lights, gages
and DIC messages are explained on the following pages.

{CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bags, it
means that something may be wrong with the
air bag system. The passenger's air bags
could in¯ate even though the switch is off. If
this ever happens, do not let anyone whom the
national government has identi®ed as a
member of a passenger air bag risk group sit
in the passenger's position (for example, do
not secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced.
See
Air Bag Off Switch on page 1-44.
Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when your vehicle is at 10 volts or below. Have
it checked right away. Driving with the voltmeter reading
at 10 volts or below could drain your battery and
disable your vehicle.

that helps the driver maintain directional control of the
vehicle in difficult driving conditions. This is
accomplished by selectively applying any one of the
vehicle's brakes.
When you ®rst start your vehicle and begin to drive
away (6 mph (10 km/h)), especially during cold weather,
the message STABILITRAK WARMING may be
displayed in the Driver Information Center (DIC), the
instrument cluster light will be on, and a chime will
sound. This is normal. You can acknowledge this
message by pressing the RESET button. The
Stabilitrak
žSystem performance is affected until the
message, STABILITRAK READY, is displayed in
the DIC.
The WAIT FOR STABILITRAK message may be
displayed in the DIC after exceeding 19 mph (30 km/h)
for 10 seconds if the steering is not centered. The
system is off until the STABILITRAK ACTIVE message
is displayed.
The STABILITRAK ACTIVE message will come on
when the system is operating. See
DIC Warnings and
Messages on page 3-57for more information. You
may also feel or hear the system working. This
is normal.The instrument cluster light
will come on and a chime
will sound to let you
know if there is a problem
with the system.

Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
See
Engine Compartment Overview on page 5-12for
information on location.
Engine Overheating
You will ®nd an COOLANT OVER TEMP message or
an ENGINE HOT, STOP ENGINE message displayed in
the Driver Information Center (DIC). You will also
hear a chime. There is also an engine coolant
temperature gage on the instrument panel cluster. See

Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be driven to
a safe place in an emergency situation. If an overheated
engine condition exists and the DIC message ENGINE
HOT, STOP ENGINE is displayed, an overheat
protection mode which alternates ®ring groups of
cylinders helps prevent engine damage. In this mode,
you will notice a signi®cant loss in power and engine
performance. Driving extended miles (km) in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil and
reset the oil life system. See
Engine Oil on
page 5-13.
