Climate Control and Heated/Cooled Seat Operation
during a Remote Start
Passenger Air Bag and Safety Belt
Indicator Information
When performing a DTC check
using a scan tool on some 2014
Malibu models, the Electronic
Brake Control Module (EBCM)
may have a DTC C025E SYM5A
(Vacuum Sensor Signal Is Not
Plausible) set in history. When
the DTC is cleared, it may set
again and immediately go to
history during the next igni-
tion cycle. No messages will be
displayed on the Driver Informa-
tion Center and no Malfunction
Indicator Lamps will be illumi-
nated on the instrument cluster.
Do not replace any components
for this condition. This is a nor-
mal operating characteristic. The
DTC clears when the diagnostic
runs and passes.

The following systems on the 2014
Silverado 1500 and Sierra 1500 may
operate during a remote vehicle start:
• Climate controls
• Rear window defogger
• Heated seats
• Cooled seats
• Heated steering wheel
Climate Control (HVAC)
Settings
During a remote start, the HVAC settings
will operate at the previous HVAC settings
when the vehicle was last turned off. If
the owner desires a certain HVAC setting
during a remote start, the HVAC mode,
blower and temperature should be set
prior to turning off the truck.
Rear Window Defogger
During a remote start, the rear window
defogger will turn on if the outside temper-
ature is 44° F (7° C) or below. It will stay
on for 10 minutes when the key is turned
to Run/On. The rear window defogger in-
dicator will not be illuminated until the key
is turned to Run/On.
Heated Seats
During a remote start, the heated seats
will turn on (if enabled) to the high setting
when the ambient temperature is below
50° F (10° C). They will turn off when the
key is turned to Run/On. The heated seat
indicators will not be illuminated when the
heated seats are on during a remote start.
To enable the heated seats to operate
during a remote start, go to the Vehicle
Settings menu.
Cooled Seats
During a remote start, the cooled seats
will turn on (if enabled) to the high setting
when the ambient temperature is above
80° F (27° C). They will turn off when the
key is turned to Run/On. The cooled seat
indicators will not be illuminated when the
cooled seats are on during a remote start.
To enable the cooled seats to operate
during a remote start, go to the Vehicle
Settings menu.
Heated Steering Wheel
During a remote start the heated steering
wheel does not turn on.
