The recirculation mode cannot be used with oor, defog,
or defrost modes. If recirculation is selected with one of
those modes, the indicator light ashes three times and
then turns off. The air conditioning compressor also
comes on when this mode is activated. While in
recirculation mode the windows may fog when the
weather is cold and damp. To clear the fog, select either
the defog or defrost mode and increase the fan speed.
The recirculation mode can be turned off by pressing the
outside air button, or by turning off the ignition.
;(Outside Air):Press this button to turn on the
outside air mode. When this mode is selected, air from
outside the vehicle circulates throughout the vehicle.
An indicator light on the button comes on to show
that it is activated. The outside air mode can be
used with all modes, but it cannot be used with the
recirculation mode.
Air Conditioning
#
(Air Conditioning):Press this button to turn the air
conditioning (A/C) compressor on and off. When air
conditioning is selected, an indicator light comes on to
show that the air conditioning has been activated.
Pressing this button when the outside temperature is
too cool for air conditioning makes the air conditioning
indicator ash three times and then turn off to let
you know the air conditioning mode is not available.
If the air conditioning is on and the outside temperature
drops below a temperature which is too cool for air
conditioning to be effective, the air conditioning light
turns off to show that the air conditioning mode has
been canceled.
On hot days, open the windows long enough to let hot
inside air escape. This helps to reduce the time it
takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
The air conditioning system removes moisture from the
air, so a small amount of water might drip underneath
the vehicle while idling or after turning off the engine.
This is normal.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle. The pictures help to 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 your vehicle’s functions. As the
details show on the next few pages, some warning lights
come on brie y 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
as 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 your vehicle’s
warning lights and gages. They can be a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with warning lights and gages.
SeeDIC Warnings and Messages on page 3-66for
more information.

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol.
The system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the airbag
sensor, the pretensioners, the airbag modules, the
wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 1-69.
This light will come on
when you start your
vehicle, and it will ash for
a few seconds. The light
should go out and the
system is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your
airbag system may not work properly. Have your vehicle
serviced right away.{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not in ate in a crash, or they
could even in ate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away.
The airbag readiness light should ash for a few seconds
when you start the engine. If the light does not come on
then, have it xed immediately. If there is a problem with
the airbag system, an airbag Driver Information Center
(DIC) message may also come on. SeeDIC Warnings
and Messages on page 3-66for more information.

{CAUTION:
If the right front passenger’s airbag is turned off
for a person who is not in a risk group identi ed
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 in ate 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
identi ed by the national government.
SeeAirbag Off Switch on page 1-78for more on
this, including important safety information.
{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could in ate even though the switch is off.
If this ever happens, do not let anyone whom
the national government has identi ed as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing child
restraint in the right front passenger’s seat)
until you have your vehicle serviced. SeeAirbag
Off Switch on page 1-78andAirbag Readiness
Light on page 3-40for more on this, including
important safety information.
If the word ON or the on symbol is lit, it means that
the right front passenger’s frontal airbag is enabled
(may in ate). SeeAirbag Off Switch on page 1-78for
more on this, 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.

Passenger Airbag Status Indicator
If your vehicle has the passenger sensing system, your
overhead console will have a passenger airbag status
indicator.
When you start the vehicle, the passenger airbag status
indicator will light ON and OFF, or the symbol for on
and off, for several seconds as a system check. Then,
after several more seconds, the status indicator will
light either ON or OFF, or either the on or off symbol to
let you know the status of the right front passenger’s
frontal airbag.If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger’s frontal airbag is enabled (may in ate).
{CAUTION:
If the on indicator comes on when you have a
rear-facing child restraint installed in the right
front passenger’s seat, it means that the
passenger sensing system has not turned off
the passenger’s frontal airbag. A child in a
rear-facing child restraint can be seriously
injured or killed if the right front passenger’s
airbag in ates. This is because the back of the
rear-facing child restraint would be very close
to the in ating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on. United States
