Warning Lights, Gages, and
Indicators
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 prevent injury.
Warning lights come on when there may be or is
a problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there may
be a problem, check the section that explains what to do.
Follow this manual’s advice. Waiting to do repairs can be
costly and even dangerous.

Instrument Panel Cluster
The instrument cluster is designed to show how the vehicle is running. It indicates how fast the vehicle is going,
about how much fuel the fuel tank has left and many other things needed to drive safely and economically.United States version shown, Canada similar
3-30

Speedometer and Odometer
The speedometer shows the vehicle’s speed in both
miles per hour (mph) and kilometers per hour (km/h).
The vehicle’s odometer works together with the
Driver Information Center (DIC). The Trip odometer
can be set. See “Trip Odometer” underDIC Operation
and Displays (Using DIC Buttons) on page 3-47or
DIC Operation and Displays (Using Trip Odometer
Reset Stem) on page 3-52for more information.
The odometer mileage can be checked while the
vehicle is not running. Simply press the trip stem on
the instrument panel cluster.
If the vehicle ever needs a new odometer installed,
the new one will be set to the correct mileage total
of the old odometer.
Trip Odometer
The trip odometer can show how far the vehicle has
been driven since the trip odometer was last set to zero.
Press the trip stem to toggle between the trip odometer
and the regular odometer. Hold the trip stem for
approximately one second while the trip odometer
is displayed to reset it.
To display the odometer reading with the ignition off,

Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime comes on for
several seconds to remind people to fasten their safety
belts, unless the driver safety belt is already buckled.
The safety belt light also
comes on and stay on for
several seconds, then
it ashes for several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor
the light comes on.
Airbag Readiness Light
There is an airbag readiness light on the center
overhead console, which shows the airbag symbol.
The system checks the airbag’s electrical system for
malfunctions. The light indicates if there is an electrical
problem. The system check includes the airbag sensors,
the airbag modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 1-67.
This light comes on when
the vehicle is started,
and ashes for a few
seconds. Then the light
should go out. This means
the system is ready.
3-32

If the airbag readiness light stays on after the vehicle is
started or comes on while driving, the airbag system
may not work properly. Have the vehicle serviced
by your dealer/retailer.
{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inate in a crash, or they could even inate
without a crash. To help avoid injury, have the
vehicle serviced right away.
Airbag Off Light
If the vehicle has an airbag on-off switch in the glove
box, it also has a passenger airbag status indicator
located in the overhead console.
When the vehicle is started, the passenger airbag status
indicator will light ON and OFF, or the symbol for on
and off, will light for several seconds as a system check.
Then, after several more seconds, the status indicator
ON or OFF, or either the on or off symbol, will light to
let you know the status of the right front passenger
frontal airbag.United States
Canada
3-33

When the right front passenger airbag is manually
turned off using the airbag on-off switch in the glove box,
the indicator light OFF or the off symbol will come on and
stay on as a reminder that the airbag has been turned off.
This light will go off when the airbag has been turned on.
SeeAirbag Off Switch on page 1-76for more on this,
including important safety information.
{CAUTION:
If the right front passenger’s airbag is turned off
for a person who is not in a risk group identied
by the national government, that person will not
have the extra protection of an airbag. In a crash,
the airbag will not be able to inate and help
protect the person sitting there.
Do not turn off the passenger’s airbag unless the
person sitting there is in a risk group identied by
the national government. SeeAirbag Off Switch
on page 1-76for more on this, including important
safety information.

{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. For example, the right
front passenger airbag could inate even though
the airbag on-off switch is turned off.
To help avoid injury to yourself or others, have the
vehicle serviced right away. SeeAirbag Readiness
Light on page 3-32for more information, including
important safety information.
If the word ON or the on symbol is lit, it means that
the right front passenger frontal airbag is enabled (may
inate). SeeAirbag Off Switch on page 1-76for more
information, including important safety information.
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 airbag on-off switch.
See your dealer/retailer for service.
Charging System Light
This light comes on briey
when the ignition key is
turned to START, but the
engine is not running, as a
check to show it is working.
If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 3-56for
more information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
3-35

Voltmeter Gage
When the engine is not
running, but the ignition
is on, this gage shows the
battery’s state of charge
in DC volts.
When the engine is running, the gage shows the
condition of the charging system. The charging system
regulates voltage based on the state of the battery for
improved fuel economy and battery life. The gage can
transition from a higher to lower or a lower to higher
reading. This is normal. Readings between the low
and high warning zones indicate the normal operating
range. The gage can also read low during the fuel
economy mode.Readings in the low warning zone can 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 full power. If there
is a problem with the battery charging system, this light
comes on or the SERVICE BATTERY CHARGING
SYSTEM DIC message displays. SeeDIC Warnings
and Messages on page 3-56andCharging System
Light on page 3-35for more information.
