Windows
{WARNING:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome by the extreme heat and
suffer permanent injuries or even death from heat
stroke. Never leave a child, a helpless adult, or a
pet alone in a vehicle, especially with the windows
closed in warm or hot weather.
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).

WARNING: (Continued)
increased stopping distance which can cause a
crash and injury. Make sure the floor mat does not
interfere with the accelerator or brake pedal.
Use the following guidelines for proper floor mat usage.
.The original equipment floor mats were designed
for your vehicle. If the floor mats need replacing, it
is recommended that GM certified floor mats be
purchased. Non-GM floor mats may not fit properly
and may interfere with the accelerator or brake
pedal. Always check that the floor mats do not
interfere with the pedals.
.Use the floor mat with the correct side up. Do not
turn it over.
.Do not place anything on top of the driver side
floor mat.
.Use only a single floor mat on the driver side.
.Do not place one floor mat on top of another.
Convenience Net
Use the convenience net, located in the rear, to store
small loads as far forward as possible. The net should
not be used to store heavy loads.
Sunroof
If the vehicle has a power
sunroof, the switches are
located on the overhead
console.
To open or close the sunroof, the ignition must be on or
Retained Accessory Power (RAP) must be active. See
Retained Accessory Power (RAP) on page 3‑27.
Express Open: The express open feature will operate
from the closed or partially open position. To express
open the power sunroof, fully press the driver's side
switch rearward once. To stop the sunroof glass in a
desired position other than to the express-open
position, press the switch again, in either direction, to
stop the movement. If the sunshade is in the closed
position, it will open with the sunroof, or it can be
opened manually.

Vent Open:To open the power sunroof to the vent
position from the closed position, press and hold the
passenger's side sunroof switch forward. The rear of
the sunroof panel will tilt upward to the full vent position.
The sunshade must be opened manually.
Express Close: The express close feature will operate
from the open or partially open position. To express
close the power sunroof, fully press the driver side
switch forward once. To stop the sunroof glass in a
desired position other than closed, press the switch
again in either direction. The sunshade must be closed
manually.
Close: To close the power sunroof, operate the controls
according to one of the following:
.From the open position, press and hold the driver's
side sunroof switch forward. The sunshade must
be closed manually.
.From the vent position, press and hold the
passenger side sunroof switch rearward.
Anti-Pinch: If an object is in the path of the sunroof
while it is closing, the anti-pinch feature will detect the
object and stop the sunroof from closing at the point of
the obstruction. The sunroof will then return to the
full-open or vent position. To close the sunroof once it
has re-opened, refer to the two options previously
described under the “Close”feature instructions.
Dirt and debris may collect on the sunroof seal or in the
tracks that could cause an issue with sunroof operation,
noise or plug the water drainage system. Periodically
open the sunroof and remove any obstacles or loose
debris. Wipe the sunroof seal and roof sealing area
using a clean cloth, mild soap, and water. Do not
remove grease from sunroof.
