Page 138 of 362

In AUTO mode the system cools and dehumidies the
air inside the vehicle. Also while in AUTO mode,
the system maximizes its performance by using
recirculation as necessary.
Heating:On cold days when using manual operation of
the automatic system, use oor mode to deliver air to
the oor outlets. To warm or cool the air delivered, push
the temperature buttons to the desired setting.
To use the automatic mode, turn the knob to AUTO and
adjust the temperature by pressing the temperature
buttons.
When the heater is in use, there might be slight noise or
vibration during Auto Stops. This is due to the coolant
circulation pump that continues to circulate heat through
the system during the engine Auto Stop.
The heater works best if the windows are kept closed.
h(Recirculation):Press the button to turn on
the recirculation mode. The air inside the vehicle
recirculates through the climate control system and the
vehicle, not from outside the vehicle. This mode is
helpful when trying to limit odors from entering
the vehicle and for maximum air conditioning
performance in hot weather. When the button ispressed, an indicator light above the button comes on.
The recirculation indicator light blinks three times if
recirculation is used in a mode in which it cannot
function. Only use this mode when it is needed for
comfort, since window fogging rapidly occurs if the air
conditioning compressor is not engaged.
Press this button to cancel the auto recirculation
feature. Each time the vehicle is started, the system
reverts to the auto recirculation function.
If recirculation is selected while in defrost, defog or oor
mode, the light on the button ashes three times and
then goes out to indicate that this is not allowed. This is
to prevent window fogging.
When the weather is cool or damp, operating the
system in recirculation for extended periods of time can
cause fogging of the vehicle’s windows. To clear the
fog, select either defog or defrost. Make sure the
air conditioning is on. Allow the air conditioning to run
automatically to help dehumidify the air.
N(Hybrid Air Conditioning):This setting balances
fuel economy and air conditioning comfort. When
hybrid A/C is used in warm weather, you may notice
more frequent auto stops and the cabin may be warmer
as compared to normal air conditioning.

Maximum Air Conditioning
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the
Cvent mode.
2. Select the highest fan speed.
3. Select
#air conditioning.
4. Select the
hrecirculation mode.
5. Select the coolest temperature.
Using these settings together for long periods of time
may cause the air inside of the vehicle to become too dry.
To prevent this from happening, after the air in the vehicle
has cooled, turn the recirculation mode off.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to choose from
to clear fog or frost from the windshield. Use the defog
mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to remove
fog or frost from the windshield more quickly.
-(Defog):Turn the mode knob to this position to
select the defog setting, which delivers air to the oor
and windshield outlets. Use this setting to clear the
windows of fog or moisture.
0(Defrost):Turn the mode knob to this position to
defrost the windshield. The system automatically
controls the fan speed if defrost is selected from the
AUTO mode. If the outside temperature is 40°F (4°C) or
warmer, the air conditioning compressor automatically
runs to help dehumidify the air and dry the windshield.
The air conditioning indicator light blinks three times
if the compressor is turned off while in this mode.
The engine will not perform Auto Stops when the defrost
mode is on.

Keep the path under the front seats clear of
objects to help circulate the air inside of the vehicle
more effectively.
When an objectionable odor outside the vehicle is
encountered, use the recirculation mode, with the
temperature knob at a comfortable setting to prevent
the odor from entering the vehicle through the
ventilation system. This can be helpful when
driving through a long tunnel with poor ventilation.
However, extended usage of this mode in cold
or cool weather can cause window fogging.
Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages that
may be on your 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 your warning lights and gages could also save you
or others from injury.Warning lights come on when there could be or there
is a problem with one of your 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 could be or there 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. Follow this manual’s
advice. Waiting to do repairs can be costly — and
even dangerous. Get to know your warning lights and
gages. They are a big help.

Speedometer and Odometer
Your speedometer lets you see your speed in miles
per hour (mph) or kilometers per hour (km/h). See
DIC Vehicle Personalization on page 3-51for more
information.
Your odometer shows how far your vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
Your vehicle has a tamper resistant odometer. The
digital odometer will read 999,999 if someone tries to
turn it back.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to
the mileage total of the old odometer, then it must
be. But if it can’t, then it is 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.
Trip Odometer
The trip odometer can tell you how far you have driven
since you last reset it.
The trip odometer is accessed and reset through the
Driver Information Center (DIC). SeeDIC Operation and
Displays on page 3-44for more information.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
Your vehicle has auto stop and the indicator for this is
on the tachometer. For more information seeAuto
Stop Mode on page 3-42.

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, seeAirbag
System on page 1-54.
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 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

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 3-46
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
away. If you must drive a short distance with the light on,
be certain to turn off all the accessories, such as
the radio and air conditioner.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to ON/RUN. If it does not come on then,
have it xed so it will be ready to warn you if there
is a problem.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does
not release fully. If it stays on after your parking brake
is fully released, it means you have a brake problem.

The Driver Information Center (DIC) may display a
BRAKE FLUID message. SeeDIC Warnings and
Messages on page 3-46for more information.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice that the
pedal is harder to push or the pedal may go closer to
the oor. It may take longer to stop. Try turning off and
restarting the vehicle one or two times, if the light is
still on, have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-27.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning
light on can lead to an accident. If the light
is still on after you have pulled off the road
and stopped carefully, have the vehicle towed
for service.
Antilock Brake System
Warning Light
This light will come
on briey when you
start the engine.
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, you still have brakes, but you do
not have antilock brakes. If the regular brake system
warning light is also on, you do not have antilock
brakes and there is a problem with your regular brakes.

Electronic Stability Control (ESC)/
Traction Control System (TCS)
Indicator/Warning Light
This light is located
in the center of the
instrument panel cluster.
For vehicles that have the Electronic Stability Control
(ESC) system or the Traction Control System (TCS),
this warning light should come on briey when the
engine is started.
If the warning light does not come on then, have it xed
so it will be ready to warn you if there is a problem.
This light, along with the appropriate Driver Information
Center (DIC) messages, indicates when the ESC
system and the TCS are working or are disabled.If this light is on and not ashing, the TCS and
potentially the ESC system have been disabled. Check
your DIC messaging to determine which feature(s) is
no longer functioning and whether it is because of
the driver turning off the feature(s), or the system may
not be working properly and your vehicle requires
service. If the TCS is disabled, wheel spin will not be
limited. If the ESC system is disabled, the system
will not aid in maintaining vehicle directional control.
In either case, adjust your driving accordingly.
If the light is on and ashing, the TCS or the ESC
system is actively working. Check the DIC messaging
for details to determine which system is working.
If the LOW TRACTION message appears, the system
is limiting wheel spin. If the ESC ACTIVE message
appears, the system is aiding in maintaining vehicle
directional control.
SeeElectronic Stability Control (ESC) on page 4-8and
Traction Control System (TCS) on page 4-6for more
information.
