Chevrolet 2013 Express Owner's Manual page 43

Rear Swing Out Windows
The vehicle also has rear swing out
windows. The rear swing-out
windows work the same way as the
side swing out window, but the latch
is located at the bottom edge of the
window.
Enhanced Technology
Glass
The vehicle may be equipped with
Enhanced Technology Glass (ETG).
ETG is part of the overall occupant
protection system on passenger
vans. ETG may help to keep
passengers sitting next to these
fixed windows from being ejected
through the glass in some, but not in
all crashes. Even with this glass,
safety belts must still be worn at all
times. For passenger vans, use only
ETG glass approved for the vehicle
for replacement when damaged.
