Climate Control Influence on
eAssist Operation and Fuel
Economy (If Equipped)
The climate control system depends
on other vehicle systems for heat
and power input. Certain climate
control settings can lead to higher
fuel usage and/or fewer auto stops.
The following climate control
settings use more fuel:
. Comfort air conditioning mode.
. The defrost mode.
. Extreme temperature settings,
such as 15 °C (60 °F) or 32 °C
(90 °F).
. High fan speed settings. To help reduce fuel usage:
.
Use the full automatic control as
described under “Automatic
Operation.”
. Use eco air conditioning, instead
of the comfort air conditioning.
. Select a temperature setting that
is higher in hot weather and
lower in cold weather.
. Turn off the air conditioning
when it is not needed.
. Only use defrost to clear the
windows.
Automatic Operation
The system automatically controls
the fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to
the desired temperature.
When the AUTO indicator light is
on, the system is in full automatic
operation. If the air delivery mode,
fan speed, recirculation, or air
conditioning setting is adjusted, the
AUTO indicator turns off and the
selected settings will appear on the
display. To place the system in
automatic mode:
1. Press AUTO.
2. Set the temperature. Allow the system time to stabilize. Adjust
the temperature as needed for
best comfort.
To improve fuel efficiency and to
cool the vehicle faster, recirculation
may be automatically selected in
warm weather. The recirculation
light will not come on when
controlled automatically. Press
@

return to automatic operation.
To change the current mode, press
one or more of the following:
X(Defog) : Air is directed to the
windshield and side window vents.
Y(Vent) : Air is directed to the
instrument panel outlets.
[(Floor) : Air is directed to the
floor outlets.
0MAX (Defrost) : Clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield.
For best results, clear all snow and
ice from the windshield before
defrosting.
For eAssist vehicles that have the
auto defog feature, auto stops can
occur in defrost mode. In this mode,
the auto stops are shorter and less
frequent than other air delivery
modes to prevent instant fogging.
A/C (Comfort Air Conditioning) :
Press to turn the air conditioning
system on or off. If the climate
control system is turned off or the
outside temperature falls below
freezing, the air conditioner will
not run.
Pressing this button cancels
automatic air conditioning and turns
off the air conditioner. Press AUTO
to return to automatic operation and
the air conditioner runs
automatically as needed. When the indicator light is on, the air
conditioner runs automatically to
cool the air inside the vehicle or to
dry the air needed to defog the
windshield faster.
For eAssist vehicles, an auto stop
may occur if the climate control
system determines the A/C
compressor can be shut off and still
maintain comfort levels with minimal
windshield fogging.
ECO A/C (For eAssist Vehicles) :
Press to cycle between the off, eco,
and comfort air conditioning modes.
The indicator will be lit green in eco,
amber in comfort, and turns off
when there is no A/C function. If the
fan is turned off the A/C will not run.
The eco A/C setting balances fuel
economy and air conditioning
comfort. In warm weather
conditions, auto stops may occur
more frequently and the vehicle
interior may be warmer as
compared to the comfort air
conditioning. This setting allows
higher humidity inside the vehicle
and window fogging before the
engine restarts.

cooler by more than 1 °C (1 °F)
during an auto stop, the engine will
restart to ensure that comfort is
reached.
@(Recirculation) : Press to turn
on recirculation. An indicator light
comes on. Air is recirculated to
quickly cool the inside of the vehicle
or prevent outside air and odors
from entering.
Auto Defog : The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate
control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control system does not detect possible
window fogging, it returns to normal

Maintenance
Air Intake
Clear away any ice, snow, or leaves
from the air intake at the base of the
windshield that can block the flow of
air into the vehicle.
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
SeeMaintenance Schedule 0305
for replacement intervals. For more
information, see your dealer.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.
