5-46 Instruments and Controls
devices such as garage door
openers, security systems, and
home automation devices.
Do not use the Universal Remote
system with any garage door opener
that does not have the stop and
reverse feature. This includes any
garage door opener model
manufactured before April 1,1982.
Read the instructions completely
before attempting to program the
Universal Remote system. Because
of the steps involved, it may be
helpful to have another person
available to assist with programming
the Universal Remote system.
Keep the original hand-held
transmitter for use in other vehicles
as well as for future Universal
Remote system programming. It is
also recommended that upon the
sale of the vehicle, the programmed
Universal Remote system buttons
be erased for security purposes.
See“Erasing Universal Remote
System Buttons” later in this
section. When programming a garage door,
park outside of the garage. Park
directly in line with and facing the
garage door opener motor-head or
gate motor-head. Be sure that
people and objects are clear of the
garage door or gate being
programmed.
It is recommended that a new
battery be installed in the hand-held
transmitter for quicker and more
accurate transmission of the
radio-frequency signal.
Programming the Universal
Remote System
For questions or help programming
the Universal Remote system, call
1-800-355-3515 or go to
www.homelink.com.
Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before

8-4 Climate Controls
0(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
#(Eco Air Conditioning, If
Equipped): This 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. The eco a/c setting
allows higher humidity inside the
vehicle and window fogging before
the engine restarts.
Pressing the
0button during an
auto stop will restart the engine to
prevent window fogging. To reach
comfort levels quickly during an
auto stop, the engine will restart if the air conditioner is off and the
AUTO, eco
#, or A/C is selected.
The engine also restarts if the
Ois
pressed on and the system is set to
AUTO, eco
#, or A/C.

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
operation. For eAssist vehicles,
there may be shorter and less
frequent auto stops when auto
defog is in use.
To turn Auto Defog off or on, see
“Climate and Air Quality” under

outside temperature is about 4°C
(40°F) and below. The auto rear
defogger turns off automatically
after about 10 minutes, or after
five minutes if the outside
temperature is not as cold. For eAssist vehicles, auto rear
defog will only run during a remote
start and the feature is not available
in the Vehicle Personalization menu.
For vehicles with heated outside
rearview mirrors, they turn on when
the rear window defogger button is
on and help to clear fog or frost from
the surface of the mirror. See
Heated Mirrors on page 2‑16.
Notice:
Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
