14. Driver Temperature Control Up Button
Provides the driver with independent temperature con-
trol. Push the hard-key button for warmer temperature
settings or on the touchscreen, press and slide the soft-
key temperature bar towards the red arrow soft-key for
warmer temperature settings.
NOTE:
In Sync mode, this button will also automatically
adjust the passenger temperature setting at the same time.
15. Temperature Control (Uconnect® 5.0)
Press the temperature soft-key to regulate the tempera-
ture of the air inside the passenger compartment. Moving
the temperature bar into the red area, indicates warmer
temperatures. Moving the temperature bar into the blue
area indicates cooler temperatures.
Automatic Operation
1. Press the AUTO hard-key or soft-key button on the Automatic Temperature Control (ATC) Panel. 2. Next, adjust the temperature you would like the
system to maintain by adjusting the driver and pas-
senger temperature hard or soft control buttons. Once
the desired temperature is displayed, the system will
achieve and automatically maintain that comfort level.
3. When the system is set up for your comfort level, it is not necessary to change the settings. You will experi-
ence the greatest efficiency by simply allowing the
system to function automatically.
NOTE:
• It is not necessary to move the temperature settings for
cold or hot vehicles. 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 US/M customer-programmable
feature. Refer to the “Uconnect® System Settings” in
this section of the manual.

WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
• 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. If the engine has been flooded, it may start to run, but not
have enough power to continue running when the igni-
tion button/key is released. If this occurs, continue
cranking with the accelerator pedal pushed all the way to
the floor. Release the accelerator pedal and the ignition
button/key once the engine is running smoothly.
If the engine shows no sign of starting after two 15-
second periods of cranking with the accelerator pedal
held to the floor, the “Normal Starting” procedure should
be repeated.
After Starting
The idle speed is automatically controlled and will de-
crease as the engine warms up.

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
Gasoline Engine Only
The engine block heater cord is routed through the grille
by the right front tow hook.
It includes a removable cap that is secured by a tethered
strap. It also has a c-clip that is used for storage when not
in use for the winter months. During winter months,
remove the heater cord wiring assembly from itself on
the c-clip.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
• Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.

before the ignition switch can be turned to the full OFF
(key removal) position. The Key Fob can only be re-
moved from the ignition when the ignition is in the full
OFF position, and the transmission is locked in PARK
whenever the ignition switch is in the full OFF position.
NOTE:If a malfunction occurs, the system will trap the
Key Fob in the ignition switch to warn you that this
safety feature is inoperable. The engine can be started
and stopped but the Key Fob cannot be removed until
you obtain service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the ignition switch must be turned to the
ON/RUN position (engine running or not) and the brake
pedal must be pressed.
Six–Speed Automatic Transmission — If
Equipped
Chassis Cab models (with automatic transmission) may
use either the AS66RC transmission (which is equipped
with Power Take-Off (PTO) access covers on each side of
the transmission case), or the 66RFE transmission (which
has no PTO access covers).
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
The shift lever is mounted on the right side of the steering
column. You must press the brake pedal to move the shift
lever out of PARK (refer to “Brake/Transmission Shift
Interlock System” in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
Pull the shift lever toward you when shifting into RE-
VERSE or PARK, or when shifting out of PARK.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are

When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load on
the transmission locking mechanism may make it diffi-
cult to move the shift lever out of PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill
grade.
On four-wheel drive vehicles be sure that the transfer
case is in a drive position.
WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
(Continued)
WARNING! (Continued)
•Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever out of PARK with the brake
pedal released. Make sure the transmission is in
PARK before leaving the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.

Page 306 of 546

CAUTION!
•Before moving the shift lever out of PARK, you
must turn the ignition switch from the OFF posi-
tion to the ON/RUN position, and also press the
brake pedal. Otherwise, damage to the shift lever
could result.
• DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the transmission into the PARK posi-
tion:
• When shifting into PARK, pull the shift lever toward
you and move it all the way counterclockwise until it
stops. •
Release the shift lever and make sure it is fully seated
in the PARK gate.
• Look at the transmission gear position display and
verify that it indicates the PARK position.
• With brake pedal released, verify that the shift lever
will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Apply the parking brake and shift
the transmission into PARK if you must leave the vehicle.
