Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that may
be on the vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gages could also save you or others
from injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. As you will
see in the details on the next few pages, some warning
lights come on briey when you start the engine just to let
you know they are working. If you are familiar with this
section, you should not be alarmed when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when there
is a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this manual’s
advice. Waiting to do repairs can be costly – and even
dangerous. So please get to know the warning lights and
gages. They are a big help.

Instrument Panel Cluster
The instrument panel cluster is designed to let the driver know at a glance how the vehicle is running. It will show
how fast the vehicle is going, about how much fuel is in the fuel tank and many other things needed to drive safely
and economically.
3-32

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your vehicle’s odometer works together with the
driver information center. You can set a Trip A and
Trip B odometer. See “Trip Information” underDIC
Operation and Displays on page 3-51.
The odometer mileage can be checked without the
vehicle running. Simply press the odometer/trip switch
on the instrument panel cluster.
If your vehicle ever needs a new odometer installed, the
new one will be set to the correct mileage total of the old
odometer.
Tachometer
The tachometer displays
the engine speed in
thousands of revolutions
per minute (rpm).
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime
will sound for several seconds to remind you and your
passengers to buckle your safety belts. The driver
safety belt light will also come on and stay on for several
seconds, then it will ash for several more. You should
buckle your seat belt.
If the driver’s belt is
buckled, neither the chime
nor the light will come on.
3-33

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety belt.
This would only occur if the passenger airbag is enabled.
SeePassenger Sensing System on page 1-65for more
information. The passenger safety belt light will also
come on and stay on for several seconds, then it will
ash for several more.
If the passenger’s safety
belt is buckled, neither
the chime nor the light
will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The system check includes the airbag modules, the
wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 1-56.
This light will come on
when the vehicle is
started, and it will ash
for a few seconds. Then
the light should go out.
This means the system
is functioning properly.
If the airbag readiness light stays on after the vehicle
is started, or comes on as the vehicle is being driven,
there may be an electrical problem and the airbag
system may not work properly. Have the vehicle serviced
right away.
