3. When the system is set up for your comfort level, it is
not necessary to change the temperature. You will
experience the greatest efficiency by simply allowing
the system to function automatically.
NOTE:
•It is not necessary to move the temperature settings.
The system automatically adjusts the temperature,
mode, and blower speed to provide comfort as quickly
as possible.
•The temperature can be displayed in U.S. or Metric
units by selecting the Uconnect® customer-
programmable feature. Refer to the “Uconnect® Sys-
tem Settings” in this section of the manual.
To provide you with maximum comfort in the Automatic
mode, during cold start-ups the blower fan will remain
on low until the engine warms up. The blower will
increase in speed and transition into Auto mode.
Manual Operation Override
The system allows for manual selection of blower speed,
air distribution mode, A/C status and recirculation con-
trol.
The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode.
The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.
NOTE:Each of these features operates independently
from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% OAT (Organic Additive Technology)
coolant that meets the requirements of Chrysler Material
Standard MS-12106 and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes objectionable, increase blower
speed to improve airflow and clearing of the side win-
dows. Vehicle windows tend to fog on the inside in mild
but rainy or humid weather.

STARTING PROCEDURES — GASOLINE
ENGINES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
•When leaving the vehicle, always remove the key
fob from the ignition and lock your vehicle.
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
•Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured. Chil-
dren should be warned not to touch the parking
brake, brake pedal or the shift lever.
(Continued)
WARNING!(Continued)
•Do not leave the key fob in or near the vehicle, or
in a location accessible to children, and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go™ in the ACC or ON/RUN
mode. A child could operate power windows, other
controls, or move the vehicle.
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting
NOTE:Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
472 STARTING AND OPERATING

Cycle the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, cycle the ignition switch to the
LOCK/OFF position, wait 10 to 15 seconds, then repeat
the “Normal Starting” procedure.
Tip Start Feature
Cycle the ignition switch to START position and release it
as soon as the starter engages. The starter motor will
continue to run, but will automatically disengage itself
when the engine is running. If the engine fails to start, the
starter will disengage automatically in 10 seconds. If this
occurs, cycle the ignition switch to the LOCK position,
wait 10 to 15 seconds, then repeat the “Normal Starting”
procedure.
Extreme Cold Weather (Below –20°F Or−29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
Extended Park Starting
NOTE:Extended Park condition occurs when the vehicle
has not been started or driven for at least 35 days.
1. Install a battery charger or jumper cables to the battery
to ensure a full battery charge during the crank cycle.
2. Cycle the ignition in the START position and release it
when the engine starts.
3. If the engine fails to start within ten seconds, cycle the
ignition to the STOP (OFF/LOCK) position, wait five
seconds to allow the starter to cool, then repeat the
Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow
the starter to cool for at least 10 minutes, then repeat
the procedure.

STARTING AND OPERATING 473

CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
(Continued)
WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
•If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emergen-
cies” for further information.
