2015 Ram Cargo Van heater

The rear blower and temperature controls for the rear
seat passengers are located in the headliner, near the
center of the vehicle.Rear Blower Control
The primary control for the rear blower is on the front
climate control unit, located on the instrument panel.
Only when the front control for the rear blower is in the
REARposition do the second row seat occupants have
control of the rear blower speed.
The rear blower control, located in the rear overhead
console, has an off position and a range of blower speeds.
This allows the second row seat occupants to control the
volume of air circulated in the rear of the vehicle.
CAUTION!
Interior air enters the Rear Manual Climate Control
system through an intake grille, located in the right
side trim panel behind the third row seats. The
heater outlets are located in the right side trim panel,

When rear controls are locked by the front system, the
lock symbol on the temperature knob is illuminated, and
the rear overhead adjustments are inoperable.
Rear Mode Control
Headliner Mode
Air comes from the outlets in the headliner. Each
of these outlets can be individually adjusted to
direct the flow of air. Moving the air vanes of the outlets
to one side will shut off the airflow.
Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE: In many temperature positions, the Bi-Level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Floor Mode
Air comes from the floor outlets.

2. Rotate the Rear Blower, Rear Temperature and theRear Mode Control knobs to suit your comfort needs.
3. ATC is selected by adjusting the rear blower knob counterclockwise to AUTO.
Once the desired temperature is displayed, the ATC
System will automatically achieve and maintain that
comfort level. When the system is set up for your comfort
level, it is not necessary to change the settings. 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
fan speed to provide comfort as quickly as possible.
• The temperature can be displayed in English or Metric
units by selecting the “Display Units of Measure in”
customer-programmable feature. Refer to the “Elec-
tronic Vehicle Information Center (EVIC) — Customer-
Programmable Features” in this Section.
Rear Blower Control
The rear blower control knob can be manually set to off,
or any fixed blower speed, by rotating the knob from low
to high. This allows the rear seat occupants to control the
volume of air circulated in the rear of the vehicle.

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.
OAT coolant (conforming to MS.90032) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
Before 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
fresh air with the blower setting on high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

soon as the starter engages. The starter motor will
continue to run, and it will disengage automatically
when the engine is running.
3. If the engine fails to start, the starter will disengage automatically in 10 seconds. If this occurs, turn the
ignition switch to the OFF position, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure
(Steps 1–3 above).
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
pressed to shift out of PARK.
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.
If The Engine Fails To Start
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.
440 STARTING AND OPERATING

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.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
The engine block heater cord is routed under the hood on
the driver’s side of the vehicle. It has a removable cap
that is located on the driver side of the Integrated Power
Module.
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 or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
