Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO),
follow these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move
your vehicle in or out of the area.
•If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is
set at high speed. DO NOT use the recirculation
mode.
(Continued)
WARNING!(Continued)
•If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.

off unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
6. Rear Defrost Light
This indicator will illuminate when the rear win-
dow defroster is on. The rear window defroster
automatically turns off after 20 minutes.
7. Low Fuel Light
When the fuel level reaches approximately 2.0 gallon
(7.6L) this light will turn on, and remain on until fuel is
added.
8. Fuel Gauge
When the ignition switch is in the ON/RUN position, the
digital scale will show the level of fuel remaining in the
fuel tank.
NOTE:The fuel gauge and range will not immediately
update accurately when refueling with the engine on.
9. Turn Signal Indicators
The arrows will flash in unison with the exte-
rior turn signal, when using the turn signal
lever.
10. Temperature Gauge

look under the hood yourself, see “Maintaining Your
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
11. Engine Temperature Warning Light
This light warns of an overheated engine condition. The
engine coolant temperature indicator will illuminate and
a single chime will sound after reaching a set threshold.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information.

NOTE:
•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•The use of the Recirculation mode in cold or damp
weather could cause windows to fog on the inside,
because of moisture buildup inside the vehicle. Se-
lect the outside air position for maximum defogging.
•Recirculation can be used in all modes except for
Defrost.
•The A/C can be deselected manually without dis-
turbing the mode control selection.
3. Blower Control
Rotate this control to regulate the amount of air forced
through the ventilation system in any mode. The blower
speed increases as you move the control to the right from
the “0” (OFF) position. There are four blower speeds.
4. A/C Button
Push this button to engage the Air Conditioning. A light
will illuminate when the Air Conditioning system is
engaged.
MAX A/C
For maximum cooling, use the A/C and recirculation
modes at the same time.
ECONOMY MODE
If economy mode is desired, push the A/C button to turn
OFF the indicator light and the A/C compressor. Then,
move the temperature control to the desired temperature.
5. Rear Defrost Control
Push and release the Rear Defrost Control button to turn
ON the rear window defroster and the heated outside
mirrors (if equipped). An indicator will illuminate when
the rear window defroster is ON. The rear window
defroster automatically turns OFF after 20 minutes.

Rear Window Defrosting
Push and release the rear window defrost button to turn
the function on/off.
The activation of the function is indicated by the rear
defrost warning light on the instrument panel switching
on. The function is automatically deactivated after 20
minutes.
If equipped, push the rear defrost button to activate
defrosting of door mirrors and heated rear window.
NOTE:Do not affix stickers to the inside of the heated
rear window over the heating filaments, to avoid damage
that might cause them to stop working properly.
Air Recirculation
Push and release the Air Recirculation button, so that the
LED on the button switch is on, to enter recirculation
mode. It is advisable to switch internal air recirculation
on while standing in traffic or in tunnels to prevent the
introduction of polluted air.
Do not use the function for a long time, particularly if
there are many passengers on board, to prevent the
windows from misting up.
NOTE:Internal air recirculation makes it possible to
reach the required heating or cooling conditions more
quickly depending on the mode selected. Do not use the
internal air recirculation function on rainy/cold days as it
would considerably increase the possibility of the win-
dows misting.

The climate control system can recognize extremely cold
(or extremely hot) conditions in the passenger compart-
ment and consequently provide optimal management of
the system’s capabilities.
NOTE:The reference temperature is 72° F (22° C) for
optimal comfort management.
The automatically controlled parameters and functions are:
•air temperature at the driver/front passenger side
vents;
•fan speed (continuous variation of the air flow);
•compressor engagement (for cooling/dehumidifying
the air);
•air recirculation.
All these functions can be adjusted manually by operat-
ing the system, selecting one or more functions and
modifying their parameters.
Automatic control of the functions will be suspended: the
system will only override the settings for safety reasons.
Manual selections always take priority over automatic
ones and are stored until the AUTO button is pushed or
the system itself intervenes for specific safety reasons.
The amount of air introduced into the passenger com-
partment is not affected by car speed; it is regulated by
the fan, which is controlled electronically.
The air temperature is always automatically controlled
according to the temperature set on the display (except
for when the system is off or in certain conditions when
the compressor is not running).
The system allows the following to be set or adjusted
manually:
•driver/passenger side air temperature;
•fan speed (continuous variation);
200 UNDERSTANDING YOUR INSTRUMENT PANEL

During completely automatic operation (AUTO), varying
the air flow and/or distribution (which are not dis-
played) causes the AUTO function LED to disappear and
the system to operate in MANUAL mode (displaying
both the flow and distribution requested).
When the compressor is deactivated, the AUTO opera-
tion remains active only if the system can guarantee
in-car comfort. Otherwise, the system switches to
MANUAL mode (the set temperatures will flash on the
display). The fan speed is the same in all the zones of the
passenger compartment.
Adjusting The Air Temperature
Rotate the Driver Temperature Control, or the Passenger
Temperature Control, dial clockwise or anti clockwise, to
adjust the air temperature in the front left (Driver Tem-
perature Control) or right (Passenger Temperature Con-
trol) zone of the passenger compartment.
The set temperatures are shown on the displays.
Push the SYNC button to align the air temperature
between the two zones.
Turn the Passenger Temperature Control knob to return
to the separate management of air temperatures in the
two zones.
Turning the control knobs completely in one direction or
the other activates the#HI#(maximum heating) or#LO#
(maximum cooling) functions respectively.
To deactivate these functions, turn the temperature knob
to the desired temperature.
Air Distribution Selection
By pushing the Mode Control buttons (Up/Down/Right
arrows), it is possible to set one of the seven possible air
distributions manually:
•Up Arrow – Air flow to the windshield and front side
window diffusers to defrost them. Use Defrost mode

In automatic operation, recirculation is managed auto-
matically by the system according to outside environ-
mental conditions.
NOTE:
•The engagement of the recirculation system makes it
possible to reach the required heating/cooling condi-
tions faster. It is, however, inadvisable to use it on
rainy/cold days as it would considerably increase the
possibility of the windows misting up inside (espe-
cially if the climate control system is off ). When the
outside temperature is low, recirculation is forced off
(air drawn in from the outside) to prevent the win-
dows from misting up.
•It is inadvisable to use internal air recirculation when
the outside temperature is low, since the windows
could mist up rapidly.
Climate Control System Compressor
Push the A/C Control button to activate/deactivate the
compressor (activation is indicated by the LED on the
button switching on).
The system remembers that the compressor has been
switched off, even after the engine has stopped.
When the compressor is switched off, the system deacti-
vates air recirculation to prevent the windows from
misting up.
Pushing the A/C button will stop the AUTO MODE (the
AUTO LED will switch off). To restore automatic control
of compressor engagement, push the AUTO button
again.
