Voltmeter Gauge (Base
Level Cluster)
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 0127. 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.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety 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
safety 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 safety belt is buckled,
neither the light nor the chime
comes on.

INSTRUMENTS AND CONTROLS 127
When the vehicle is started, the
passenger airbag status indicator will
light the symbol for on and off for
several seconds as a system check.
Then, after several more seconds, the
status indicator will light either the on
or off symbol to let you know the
status of the front outboard passenger
frontal airbag and knee airbag.
If 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 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 aproblem 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
the vehicle serviced right away. See
Airbag Readiness Light
0126 for
more information, including
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.
Have it checked by your dealer.
Driving while this light is on could
drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a message.
See
Battery Voltage and Charging
Messages 0141.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio and
air conditioner.
Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s
emission control on-board diagnostic
system. If this light is on while the
engine is running, a malfunction has
been detected and the vehicle may
require service. The light should come

up. If this occurs, change the fuel
brand. It may require at least one
full tank of the proper fuel to turn
the light off. SeeFuel0240.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
vehicle may affect vehicle operation.
See Add-On Electrical Equipment 0243.
See your dealer if assistance is needed. The vehicle may not pass
inspection if:
.
The light is on when the engine is
running.
. The light does not come on when
the ignition is in Service
Only Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.
Brake System Warning
Light
The vehicle brake system consists of
two hydraulic circuits. If one circuit is
not working, the remaining circuit can still work to stop the vehicle. For
normal braking performance, both
circuits need to be working.
If the warning light comes on, there is
a problem with the braking system.
Have the brake system inspected
right away.
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is a
problem.
If the light comes on and stays on,
there is a base brake problem.
{Warning
The brake system might not be
working properly if the brake
system warning light is on. Driving

When the remaining oil life is low, the
CHANGE ENGINE OIL SOON message
will appear on the display. See Engine
Oil Messages 0144. The oil should be
changed as soon as possible. See
Engine Oil 0250. In addition to the
engine oil life system monitoring the
oil life, additional maintenance is
recommended. See Maintenance
Schedule 0311.
The Oil Life display must be reset
after each oil change. It will not reset
itself. Do not reset the Oil Life display
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until the
next oil change. To reset the engine
oil life system, press and hold SEL for several seconds while the Oil Life
display is active. See

If you try to use the HUD image as
a parking aid, you may misjudge
the distance and damage your
vehicle. Do not use the HUD image
as a parking aid.
The HUD information can be
displayed in various languages in
some vehicles. The speedometer
reading and other numerical values
can be displayed in either English or
metric units.

. Nothing is covering the HUD lens.
. HUD brightness setting is not too
dim or too bright.
. HUD is adjusted to the proper
height.
. Polarized sunglasses are not worn.
