Windows
{Warning
Never leave a child, a helpless
adult, or a pet alone in a vehicle,
especially with the windows
closed in warm or hot weather.
They can be overcome by the
extreme heat and suffer
permanent injuries or even death
from heat stroke.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof, if equipped.
Power Windows
{Warning
Children could be seriously
injured or killed if caught in the
path of a closing window. Never
leave keys in a vehicle with
children. When there are children
in the rear seat, use the window
lockout button to prevent
operation of the windows. See
Keys on page 2-1.

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.
If the vehicle is equipped 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. SeeHeated Mirrors on
page 2-19.
{Caution
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

Remote Start Climate Control
Operation (If Equipped): If the
vehicle is equipped with the remote
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. The rear defog may come on during
remote start based on cold ambient
conditions. If the vehicle has heated
or ventilated seats, they may come
on during a remote start. See
Remote Vehicle Start on page 2-9
and
Heated and Ventilated Front
Seats on page 3-9.
Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise
the automatic climate control system
may not work properly.

1. View Displayed by theCamera
2. Corners of the Rear Bumper
Displayed images may be farther or
closer than they appear. The area
displayed is limited and objects that
are close to either corner of the
bumper or under the bumper do not
display.
A warning triangle may display on
the RVC screen to show where the
Rear Parking Assist (RPA) has
detected an object. This triangle
changes from amber to red and
increases in size the closer the
object. On vehicles with the Rear Cross
Traffic Alert (RCTA), a triangle with
an arrow may also display on the
RVC screen to warn of traffic
coming from either direction when
backing. This system detects
objects coming from up to 20 m
(66 ft) from the left or right side
behind the vehicle. When an object
is detected, either three beeps
sound from the left or right side or
three Safety Alert Seat pulses occur
on the left or right side, depending
on the direction of the detected
vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out
from the back of the vehicle do not
move further back when a trailer is
towed.
With RPA, as the vehicle backs up
at speeds of less than 8 km/h
(5 mph), the sensors on the rear
bumper detect objects up to 2.5 m
(8 ft) behind the vehicle that are
within a zone 25 cm (10 in) high off
the ground and below bumper level.These detection distances may be
shorter during warmer or humid
weather. Blocked sensors will not
detect objects and can also cause
false detections. Keep the sensors
clean of mud, dirt, snow, ice, and
slush; and clean sensors after a car
wash in freezing temperatures.
{Warning
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at
speeds greater than 8 km/h
(5 mph). To prevent injury, death,
or vehicle damage, even with
parking assist, always check the
area around the vehicle and
check all mirrors before moving
forward or backing.
