Dual Automatic Climate Control
System
With this system you can control the heating, cooling,
and ventilation for the vehicle.
Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode, and the fan speed. There might be a
delay of two to three minutes before the fan comes on
when the automatic operation is used in cold weather.
For the automatic system to function, the temperature
must be set between 61°F (15°C) and 89°F (32°C).1. Adjust the temperature to a comfortable setting.
2. Press the PASS button or the up or down arrows on
the passenger side to turn the passenger
temperature set on and off. When turned on, the
passenger temperature will be the same as the driver
setting. Press the up or down arrow on passenger
side to adjust the passenger temperature setting.
When the passenger’s temperature set is off, the
passenger display will be off and the driver’s
set temperature will be for the driver and passenger.
In cold weather, the system will start at reduced
fan speeds to avoid blowing cold air into the vehicle
until warmer air is available. The system will start
out blowing air at the oor but may change
modes automatically as the vehicle warms up to
maintain the chosen temperature setting. The length
of time needed for warm up will depend on the
outside temperature and the length of time that has
elapsed since the vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then, adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center
of the instrument panel, near the windshield. For
more information on the solar sensor, see “Sensors”
later in this section.

This control has four types of operation.
Automatic can set/change the temperature only.
AUTO and temperature only will appear on the
display.

temperature and mode. The fan operates
automatically. The temperature and mode will

Semi-Automatic Mode can set/change the
temperature and fan speed. The mode operates
automatically. The fan speed and temperature will
appear on the display.
Manual can set/change the temperature, mode and
fan. The fan speed, temperature, and mode will
appear on the display.
If your vehicle has the remote start feature, the climate
control system will automatically regulate the inside
temperature of your vehicle when the remote start
system is activated. Normal operation and the last
setting of the climate control system will return after the
key is turned on.

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

odometer. See “Trip Information” underDIC Operation
and Displays on page 3-50.
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
Your 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

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 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 3-58for
more information.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a has a passenger airbag
status indicator.
When you start the
vehicle, the passenger
airbag status indicator will
light 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. Then, after several more seconds, the status
indicator will light either ON or OFF to let you know the
status of the right front passenger’s frontal airbag.
If the word ON is lit on the passenger airbag status
indicator, it means that the right front passenger’s frontal
airbag is enabled (may inate).
3-34

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 3-33for more on this, including
important safety information.
Charging System Light
This light will come on
briey when you turn on
the ignition key, 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 driving, there could be a problem
with the charging system. A charging system Driver
Information Center (DIC) message may also appear.
SeeDIC Warnings and Messages on page 3-58
for 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

Antilock Brake System
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this light
comes on briey when the
engine is started.
That is normal. If the light does not come on then,
have it xed so it will be ready to warn you if there
is a problem.
If the ABS light stays on, turn the ignition off, if the light
comes on when you are driving, stop as soon as it is
safely possible and turn the ignition off. Then start
the engine again to reset the system. If the ABS light
still stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake
system warning light is not on, your vehicle still has
brakes, but not antilock brakes. If the regular brake
system warning light is also on, your vehicle does not
have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-37.For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-58for all
brake related DIC messages.Traction Control System (TCS)

This indicates that one or more of your tires are
signicantly underinated.
A tire pressure message in the Driver Information
Center (DIC), may accompany the light. SeeDIC
Warnings and Messages on page 3-58for more
information. Stop and check your tires as soon as it is
safe to do so. If underinated, inate to the proper
pressure. SeeTires on page 5-63for more information.

This indicates that there may be a problem with the Tire
Pressure Monitor System. The light ashes for about
a minute and stays on solid for the remainder of
the ignition cycle. This sequence will repeat with every
ignition cycle. SeeTire Pressure Monitor System on
page 5-71for more information.
