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.
The air conditioning compressor does not work
when outside temperatures fall below 40°F (4°C).
Pressing this button when the outside temperature
is too cool makes the air conditioning indicator
ash three times and 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 may drip underneath
your vehicle while idling or after turning off the engine.
This is normal.
Sensors
The solar sensor, located in the defrost grille in the
middle of the instrument panel, monitors the solar
radiation. Do not cover the solar sensor or the system
will not work properly.

Warning Lights, Gages,
and Indicators
This section describes the warning lights and gages
on your vehicle.
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 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 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 get to know your vehicle’s warning lights
and gages. They can be a big help.

Speedometer and Odometer
The speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven, in either miles or kilometers.
Your vehicle has a tamper-resistant odometer. If your
vehicle needs a new odometer installed, the new
one will be set to the mileage total of the old odometer.
If this is not possible, it will be set at zero and a
label must be put on the driver’s door to show the
old mileage reading when the new odometer was
installed. If the mileage is unknown, the label should
then indicate “previous mileage unknown”.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime will come on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light
will also come on and stay
on for several seconds,
then it will ash for
several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
belt is already buckled, neither the chime nor the
light will come on.
3-41

Passenger Safety Belt Reminder Light
Several seconds after the engine is started, 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 1-70for more information.
The passenger safety belt light, located on the
instrument panel, will come on and stay on for
several seconds and then ash for several more.
This chime and light
are repeated if the
passenger remains
unbuckled and the
vehicle is in motion.
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 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, see
Airbag System on page 1-61.
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.
3-42

{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 inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the airbag readiness light
stays on after you start your vehicle.
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.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system. Your
instrument panel has 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. If you
use remote start to start your vehicle from a distance,
if equipped, you may not see the system check.United States
Canada
3-43

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 and seat-mounted side impact airbags.
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 and seat-mounted side impact
airbag are enabled (may inate).
{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 and
seat-mounted side impact airbag (if equipped).
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint would
be very close to the inating airbag. Do not use
a rear-facing child restraint in the right front
passenger’s seat if the airbag is turned on.
{CAUTION:
Even though the passenger sensing system is
designed to turn off the right front passenger’s
frontal airbag and seat-mounted side impact
airbag (if equipped) if the system detects a
rear-facing child restraint, no system is
fail-safe, and no one can guarantee that an
airbag will not deploy under some unusual
circumstance, even though it is turned off.
We recommend that rear-facing child restraints
be secured in a rear seat, even if the airbag
is or airbags are off.
If the word OFF or the off symbol is lit on the passenger
airbag status indicator, it means that the passenger
sensing system has turned off the right front passenger’s
frontal airbag and seat-mounted side impact airbag.
SeePassenger Sensing System on page 1-70for
more on this, including important safety information.
3-44

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 passenger sensing
system. See your dealer/retailer for service.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the airbag(s). SeeAirbag Readiness Light
on page 3-42for more on this, including
important safety information.
Charging System Light
This 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. A charging system
Driver Information Center (DIC) message may also
appear. SeeDIC Warnings and Messages on page 3-66
for more information. This light could indicate that
you have problems with a generator drive belt, or
another electrical problem. Have it checked right away.
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.
