When the ignition is on, the fuel
gauge indicates about how much fuel
is left in the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the
fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle should
be refueled soon.
Here are four things that some owners
ask about. None of these show a
problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel to
fill up than the gauge indicated.
For example, the gauge may have
indicated the tank was half full,
but it actually took a little more or
less than half the tank's capacity
to fill the tank.
. The gauge moves a little while
turning a corner or speeding up. .
The gauge takes a few seconds to
stabilize after the ignition is
turned on, and goes back to empty
when the ignition is turned off.
Boost Gauge (Performance
Configuration Only)
This gauge indicates boost under
heavier throttle.
It displays the air pressure level in the
intake manifold before it enters the
engine's combustion chamber.
The gauge is automatically centered at
zero every time the engine is started.
Actual 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.

Voltmeter Gauge (Base
Level Cluster Only)
Standard Theme
When the ignition is on, this gauge
indicates the battery voltage.
When the engine is running, this
gauge shows the condition of the
charging system. The gauge can
transition from a higher to lower or a
lower to higher reading. This is
normal. If the vehicle is operating
outside the normal operating range,
the charging system light comes on.
See Charging System Light 0122. Readings outside the normal operating
range can also occur when a large
number of electrical accessories are
operating in the vehicle and the
engine is left idling for an extended
period. This condition is normal since
the charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can only be driven for a
short time with the readings outside
the normal operating range. If the
vehicle must be driven, turn off all
accessories, such as the radio and air
conditioner, and unplug all chargers
and accessories.
Readings outside the normal operating
range indicate a possible problem in
the electrical system. Have the vehicle
serviced as soon as possible.
Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder
light on the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to
remind the driver to fasten their seat
belt. Then the light stays on solid
until the belt is buckled. This cycle
may continue several times if the
driver remains or becomes unbuckled
while the vehicle is moving.
If the driver seat belt is buckled,
neither the light nor the chime
comes on.

When the vehicle is started, the
passenger airbag status indicator will
light ON and OFF, or the symbol for
on and off, for several seconds as a
system check. Then, after several more
seconds, the status indicator will light
either ON or OFF, or either the on or
off symbol, to let you know the status
of the front outboard passenger
frontal airbag and knee airbag. If the word ON or the on symbol is lit
on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag and
knee airbag are allowed to inflate.
If the word OFF or the off symbol is lit
on the airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag and
knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See your
dealer for service.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have

important safety information.
Charging System Light
On some vehicles the charging system
light comes on briefly when the
ignition is turned on, but the engine is
not running, as a check to show the
light is working. It should go out when
the engine is started. For vehicles with
a reconfigurable cluster, this light may
not come on when the ignition is
turned on.
If the light stays on, or comes on
while driving, there may be a problem
with the electrical charging system.

130 INSTRUMENTS AND CONTROLS
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information about
tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of the
tires are significantly underinflated.

pressure message may also display.
Stop as soon as possible, and inflate
the tires to the pressure value shown
on the Tire and Loading Information
label. SeeTire Pressure 0322.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light will
come on at every ignition cycle. See
Tire Pressure Monitor Operation 0325.Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check the
oil level as soon as possible. Add oil
if required, but if the oil level is
within the operating range and the
oil pressure is still low, have the
vehicle serviced. Always follow the
maintenance schedule for changing
engine oil.
This light should come on briefly as
the engine is started. If it does not
come on, have the vehicle serviced by
your dealer. If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle could
be low on oil and might have some
other system problem. See your dealer.

DIC Information Displays
The following is the list of all possible
DIC information displays. Some of the
information displays may not be
available for your particular vehicle. Speed (Base Cluster) :
Shows the
vehicle speed in either kilometers per
hour (km/h) or miles per hour (mph).
Trip A or Trip B, Average Fuel
Economy, and Average Speed (Base
Cluster) / Trip 1 or Trip 2 and
Average Fuel Economy (Uplevel
Cluster) : The Trip display shows the
current distance traveled, in either
kilometers (km) or miles (mi), since
the trip odometer was last reset. The
trip odometer can be reset by pressing
and holding SEL while this display is
active.
The Average Fuel Economy display
shows the approximate average liters
per 100 kilometers (L/100 km) or
miles per gallon (mpg). This number
is calculated based on the number of
L/100 km (mpg) recorded since the
last time this menu item was reset.
This number reflects only the
approximate average fuel economy
that the vehicle has right now, and
will change as driving conditions
change. The Average Fuel Economy
can be reset along with the trip
odometer by pressing and holding SEL
while this display is active. Fuel Range and Instantaneous Fuel
Economy :
Shows the approximate
distance the vehicle can be driven
without refueling. LOW will be
displayed when the vehicle is low on
fuel. The fuel range estimate is based
on an average of the vehicle's fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank. It also shows if the
Active Fuel Management is active and
in V4 mode, or inactive and in V6 or
V8 mode. See Active Fuel Management
