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.

Climate Controls 8-5
When the indicator light is on, air is
recirculated inside the vehicle. If the
indicator light is off, outside air will
flow into the vehicle. Press AUTO or
@to return to automatic
operation.
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
Vehicle Personalization on
page 5‑39.
Rear Window Defogger
=(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. The defogger can also
be turned off by turning the ignition
to ACC/ACCESSORY or
LOCK/OFF.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization on
page 5‑39. 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, 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
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.
((Heated Steering Wheel): For
vehicles with this feature, press to
turn on or off. See Heated Steering
Wheel on page 5‑3.

equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper

.Keep the interior
temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.

driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going

(Continued)
WARNING (Continued)
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill.
Steering may also be affected
when ignition is off. You could
crash. Always have the engine
running and the vehicle in gear
when going downhill.

Driving and Operating 9-41
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARK ASSIST:If this
message occurs, take the vehicle to
your dealer to repair the system.
PARK ASSIST OFF: If the URPA
system does not activate due to a
temporary condition, this message
displays on the DIC. This can occur
under the following conditions:
.The driver has disabled the
system.
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10‑92.
.The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold weather. The message may not
clear until the frost or ice has
melted.
.An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed,
URPA will return to normal
operation.
.The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
.Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
Side Blind Zone
Alert (SBZA)
The vehicle may have a Side Blind
Zone Alert (SBZA) system. Read
this entire section before using the
system.
{WARNING
SBZA does not detect vehicles
rapidly approaching outside of the
side blind zones, pedestrians,
bicyclists, or animals. Failure to
use proper care when changing
lanes may result in injury, death,
or vehicle damage. Before
making a lane change, always
check mirrors, glance over your
shoulder, and use the turn
signals.
When the system detects a vehicle
in the side blind zone, amber SBZA
displays will light up in the side
mirrors. This indicates that it may be
unsafe to change lanes. Before
making a lane change, always
check the SBZA display, check the
outside and rearview mirrors, look
over your shoulder for vehicles and
hazards, and use the turn signal.
