Charging System Light
The charging system light
will come on briey when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays on,
or comes on while you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator drive belt, or another
electrical problem. Have it checked right away. Driving
while this light is on could drain your battery.
When this light comes on the DIC will also display the
battery not charging message. SeeDIC Warnings
and Messages on page 3-48.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
Voltmeter Gage
When your engine is not
running, but the ignition is
in RUN, this gage
shows your battery’s state
of charge in DC volts.
When the engine is running, the gage shows the condition
of the charging system. Readings between the low and
high warning zones indicate the normal operating range.
Readings in the low warning zone may occur when
a large number of electrical accessories are operating in
the vehicle and the engine is left at an idle 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.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
Oil Pressure Gage
The oil pressure gage shows the engine oil pressure in
psi (pounds per square inch) when the engine is
running. Canadian vehicles indicate pressure in
kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.United States

DIC Warnings and Messages
Warning messages are displayed on the Driver
Information Center (DIC) to notify the driver that the
status of the vehicle has changed and that some action
may be needed by the driver to correct the condition.
If there is more than one message that needs to
be displayed they will appear one after another. Some
messages may not require immediate action, but
you should press any of the four DIC buttons located on
the steering wheel or the trip odometer reset stem
located on the instrument panel cluster to acknowledge
that you received the messages and to clear them
from the display. Some messages cannot be cleared
from the display because they are more urgent.These messages require action before they can be
removed from the DIC display. You should take
any messages that appear on the display seriously and
remember that clearing the messages will only make
the messages disappear, not correct the problem.
The following are the possible messages that can be
displayed and some information about them.

to play games, watch videos, view photos, etc.
Notice:Normal operation for the RSE system may
be limited under extreme temperatures. Using
the RSE system during extreme temperatures may
cause damage to the system. Wait until the inside of
the vehicle is at a safe temperature range of
32°-140°F (0°-60°C) before using the system.
Headphones
Wireless Headphones
The RSE system may include two sets of wireless
headphones. Each headphone will have an L marked
on the left-side, for the left ear and an R marked on the
right-side, for the right ear. The L and R marks are to
show how the headphones should be worn.
OFF/ON (Power):The wireless headphones have an
OFF/ON power switch located on the left of the
earpiece. To use the headphones, turn the switch to

the headphones to OFF when not in use.The headphones will shut off automatically to save the
battery power if the RSE system is shut off or if the
headphones are out of range of the transmitter window
for more than three minutes. The transmitter window
is located on the bottom edge of the monitor. If
you move too far forward or step out of the vehicle,
the headphones will lose the audio signal.
Channel Selector:The wireless headphones have a
channel selector switch located on the right earpiece.
The channel selector switches between Channel A and
Channel B. Since each monitor has the capability to
function as two independent sources through auxiliary
input, it is necessary to transmit audio signals on
separate channels. The driver’s side monitor is
designated as Channel A, and the passenger’s side as
Channel B. The Headphone channel selector switch
must be set to the appropriate channel according to the
monitor being viewed. When the head restraint
