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.

NOTE:With the compressor off, air cannot be introduced
to the passenger compartment with a temperature lower
than the outside temperature. Moreover, under certain
environmental conditions, windows could mist rapidly
since the air is not dehumidified.
Rapid Window Demisting (MAX-DEF function)
Push the MAX-DEF button to activate (LED on button
on) the windshield and side window demisting function.
The climate control system carries out the following
operations:
•switches on the air conditioning compressor when
environmental conditions are suitable;
•switches air recirculation off;
•sets fan speed according to the engine coolant tem-
perature;
•directs air flow to windshield and front side window
diffusers;
•activates the heated rear window;
•activates the heated windshield (if equipped);
•displays the fan speed (Blower Control Indicator LED
lit).
NOTE:The Front Defrost Control (MAX-DEF) function
remains on for about three minutes from when the engine
coolant reaches the appropriate temperature.
When the function is activated, the LED on the AUTO
button switches off. With the function activated the only
possible manual adjustments are adjusting the fan speed
and turning the heated rear window off.
When the Recirculation Control, Rear Defrost Control , or
AUTO buttons are pushed, the climate control system
will deactivate the Front Defrost (MAX-DEF) function.

NOTE:The climate control system control unit stores the
temperatures set before the system was switched off and
restores them when any button of the system is pushed
(except for the A/C Control button).
To restart the climate control system in fully automatic
mode push the AUTO button.
Additional Heater (If Equipped)
This allows the passenger compartment to be heated
more quickly in cold weather conditions.
The heater switches off automatically when the required
comfort conditions are achieved.
The additional heater activates automatically depending
on the environmental conditions and with engine started.
NOTE:The heater only operates if the outside tempera-
ture and engine coolant temperature are low. The heater
will not activate if the battery voltage is too low.

range of torque converter clutch engagement. This is
done to prevent transmission damage due to overheat-
ing.
During cold temperatures, transmission operation may
be modified depending on engine coolant temperature.
Normal operation will resume once the engine tempera-
ture has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in third gear regardless of which forward gear is selected.
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. The Malfunction Indicator Light (MIL) may be illu-
minated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.

Cooling System
WARNING!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position.
•You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had
time to cool. Never try to open a cooling system
pressure cap when the radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
flushed and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the condenser.
Cooling System — Drain, Flush And Refill
NOTE:Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead
to severe internal engine damage. If any coolant is
needed to be added to the system please contact your
local authorized dealer.
If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with OAT coolant (antifreeze) (conforming to
MS.90032).

CAUTION!(Continued)
•Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
•This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (an-
tifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that al-
lows extended maintenance intervals. This engine cool-
ant (antifreeze) can be used up to ten years or 150,000
miles (240,000 km) before replacement. To prevent reduc-
ing this extended maintenance period, it is important that
you use the same engine coolant (OAT coolant conform-
ing to MS.90032) throughout the life of your vehicle.
Please review these recommendations for using Organic
Additive Technology (OAT) engine coolant (antifreeze)
that meets the requirements of Chrysler Material Stan-
dard MS.90032. When adding engine coolant (antifreeze):
•We recommend using MOPAR® Antifreeze/Coolant
10 Year/150,000 Mile Formula OAT (Organic Additive
Technology) that meets the requirements of Chrysler
Material Standard MS.90032.
•Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of Chrysler Material Stan-
dard MS.90032 and distilled water. Use higher concen-
trations (not to exceed 70%) if temperatures below
−34° F (−37° C) are anticipated.
