8-4 Climate Controls
Rear Window Defogger
= REAR (Rear Window
Defogger): Press to turn the rear
window defogger on or off.
The rear window defogger turns
off automatically after about
10 minutes. If turned on again it
runs for about five minutes before
turning off. At higher vehicle
speeds, the rear window defogger
may stay on continuously.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization on
page 5‑43. When Auto Rear Defog
is selected, the rear window
defogger turns on automatically
when the interior temperature is cold
and the outside temperature is
about 4°C (40°F) and below. The
auto rear defogger turns off
automatically after about
10 minutes. At higher vehicle
speeds, the rear window defogger
may stay on continuously.
The upper region of gridlines on the
rear window are antenna lines and
are not intended to heat when the
defogger is activated.
The heated outside mirrors turn on
when the rear window defogger
button is on. They help to clear fog
or frost from the surface of the
mirrors.
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
may damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.
Driver and Passenger Heated
Seats (If Equipped): Press
M or L
to heat the driver or passenger seat.
See Heated Front Seats on
page 3‑8.
Remote Start Climate Control
Operation: For vehicles with the
remote vehicle start feature, the
climate control system may run
when the vehicle is started remotely.
The system uses the driver's
previous settings to heat or cool the
inside of the vehicle. See Remote
Vehicle Start on page 2‑9.
The rear window defogger turns on
if it is cold outside.
