Interior Mirrors

Interior Rearview Mirrors

Adjust the rearview mirror for a clear
view of the area behind the vehicle.
Do not spray glass cleaner directly
on the mirror. Use a soft towel
dampened with water.

Manual Rearview Mirror

Push the tab forward for daytime
use and pull it rearward for
nighttime use to avoid glare of the
headlamps from behind.
Automatic Dimming
Rearview Mirror
If equipped, automatic dimming
reduces the glare of headlamps
from behind. The dimming feature
comes on when the vehicle is
started.

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 the Remote Keyless Entry
(RKE) transmitter in a vehicle with
children. When there are children
in the rear seat, use the window
lockout switch to prevent
operation of the windows. See
Keys 0 26.
