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.
84 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•To program the two remaining HomeLink® buttons,
repeat each step for each remaining button. DO NOT
erase the channels.
Reprogramming A Single HomeLink® Button
(Non-Rolling Code)
To reprogram a channel that has been previously trained,
follow these steps:
1. Cycle the ignition to the ON/RUN position.
2. Push and hold the desired HomeLink® button until
the indicator light begins to flash after 20 seconds.Do
not release the button.
3.Without releasing the buttonproceed with “Program-
ming A Non-Rolling Code” step 2 and follow all
remaining steps.
Canadian/Gate Operator Programming
For programming transmitters in Canada/United States
that require the transmitter signals to “time-out” after
several seconds of transmission.
Canadian radio frequency laws require transmitter sig-
nals to time-out (or quit) after several seconds of trans-
mission – which may not be long enough for HomeLink®
to pick up the signal during programming. Similar to this
Canadian law, some U.S. gate operators are designed to
time-out in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
1. Cycle the ignition to the ON/RUN position.

CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to the
heating elements. Labels can be peeled off after
soaking with warm water.
•Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the
window.
•Keep all objects a safe distance from the window.
ROOF LUGGAGE RACK-IF EQUIPPED
The crossbars and siderails are designed to carry the
weight on vehicles equipped with a luggage rack. The
load must not exceed 110 lbs (50 kg), and should be
uniformly distributed over the luggage rack crossbars.
Their are two attachment points inside the door jambs
that the Roof Rack crossbars attach to.

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.

Additional Electric Heater (If Equipped)
The additional electric heater ensures more rapid passen-
ger compartment heating.
It activates in cold weather conditions, if the following
conditions are verified:
•outside temperature low;
•engine coolant temperature low;
•engine on;
•fan speed set to 1st speed;
•Temperature Control knob turned completely clock-
wise to red section.
The heater is switched off when at least one of the
conditions above is no longer verified.
NOTE:The power of the electric heater is modulated
according to the battery voltage.
System Maintenance
In winter, the climate control system must be turned on at
least once a month for about 10 minutes.
Have the system inspected at a Fiat dealership before the
summer.
NOTE:The system uses R-1234yf coolant which does not
pollute the environment in the event of accidental leak-
age. Under no circumstances is the use of R-134a allowed.

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.

Selecting the footwell/windshield or only windshield dis-
tribution activates the climate control system compressor
(LED on A/C button on) and the air recirculation is set to
#outside air#intake (LED on the recirculation button off ).
This logic guarantees optimum visibility at the windows.
It is, however, always possible to manage air recirculation
and the climate control system compressor manually.
Rear Window Defrosting
Push the Rear Defrost button to activate heated rear
window defrosting.
The effective activation of the function is indicated by the
rear defrost warning light on the instrument panel
switching ON.
This function switches OFF automatically after about 20
minutes or when the engine is turned OFF. It is not
switched on automatically the next time the engine is
started.
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.
Switching Off The Climate Control System
Push the On/Off button.
With climate control system off:
•air recirculation is on, thus isolating the passenger
compartment from the outside;
•the compressor is off;
•the fan is off;
•the heated rear window can be activated / deacti-
vated.
