21. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors engine and automatic
transmission control systems. The light will illu-
minate when the key is in the ON position before engine
start. If the bulb does not come when turning the key
from OFF to ON, have the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert to serious
conditions that could lead to immediate loss of power or
severe catalytic converter damage. The vehicle should be
serviced as soon as possible if this occurs. 22. Trac Off Indicator — If Equipped
This display indicator should illuminate for approxi-
mately four seconds as a bulb check when the ignition
switch is first turned ON.
The “TRAC OFF” Indicator will flash if the traction
control is in use.
The “TRAC OFF” Indicator will illuminate if:
• The Traction Control switch has been used to turn
the system OFF.
• There is a Traction Control System malfunction
• The system has been deactivated to prevent damage
to the brake system due to overheated brake tem-
peratures.
NOTE: Extended heavy use of Traction Control may
cause the system to deactivate and turn on the TRAC and
the OFF indicators located in the instrument cluster.218 UNDERSTANDING YOUR INSTRUMENT PANEL

This is to prevent overheating of the brake system and is
a normal condition. The system will remain disabled for
about 4 minutes until the brakes have cooled. The system
will automatically reactivate and turn off the TRAC and
the OFF indicators.
If your vehicle becomes stuck in mud, ice, or snow, turn
the Traction Control System OFF before attempting to
“rock” the vehicle free.
23. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined. The trip odometer shows individual trip mileage. To
switch from odometer to trip odometer, press the Trip
Odometer button.
Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged,
GASCAP will be displayed in the instrument cluster
odometer. Tighten the fuel filler cap properly and press
the odometer reset button to turn the GASCAP message
off. If the problem continues, the message will appear the
next time the vehicle is started. See Section 7 of this
manual for more information.

ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the ON or
ACC position and the time button is pressed.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained. Clock Setting Procedure

and press the time button. Using the tip of a ballpoint pen
or similar object, press either the hour (H) or minute (M)
buttons on the radio.
2. Press the H button to set hours or the M button to set
minutes. The time setting will increase each time you
press a button.
RADIO GENERAL INFORMATION
Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help220 UNDERSTANDING YOUR INSTRUMENT PANEL

you understand and save you concern about these “ap-
parent” malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal. AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE: The radio, steering wheel radio controls (if
equipped), and 6 disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature. UNDERSTANDING YOUR INSTRUMENT PANEL 221

decrease the frequency. If you press and hold the button,
the radio will continue to tune until you release the
button. The frequency will be displayed and continu-
ously updated while the button is pressed.
Radio Data System (RDS)
The Radio Data System allows radio broadcasting sta-
tions to send data signals on a subcarrier frequency
which is added to the stereo signal. RDS was developed
to give FM receivers user-friendly features, such as
Program Service name (PS) and Program Type (PTY).
Program Service name is typically used by the broad-
caster to display the station’s name or call letters, for
example  WNIC  . Typically these are 8 characters in
length and are displayed by the radio for those stations which are broadcasting this information. PTY (Program
Type) is used to characterize the station’s program ma-
terial, for example  Rock Music  .
PTY (Program Type) Button
Pressing this button once will turn on the PTY mode for
5 seconds. If no action is taken during the 5 second time
out the PTY icon will turn off. Pressing the PTY button
within 5 seconds will allow the program format type to
be selected. Many radio stations do not currently broad-
cast PTY information.
