Keys, Doors, and Windows 21
Enhanced Technology Glass
The vehicle may be equipped with Enhanced
Technology Glass (ETG). ETG is part of the
overall occupant protection system on cargo
vans with five seating positions and
passenger vans. ETG may help keep
passengers sitting next to these fixed
windows from being ejected through the
glass in some, but not all crashes. Even with
this glass, seat belts must still be worn at
all times.
Use only ETG glass approved for the vehicle
for replacement when damaged. Cargo vans
with five seating positions and passenger
vans will have ETG glass in the rear-most
side windows and laminated glass in the
forward window of the sliding door,
if equipped. Long wheelbase cargo vans that
do not have five seating positions may also
have ETG in the rear-most side windows.
Rear Windows
Rear Side Door Windows (Cargo
Van Only)
{Warning
The vehicle may have a partition behind
the front seats or vertical metal panels
on the inside of the rear side door
windows. These are part of the occupant
protection system. Do not remove them.
Sun Visors
To block out glare, swing down the sun
visors. You can also swing them to the side.
Visor Vanity Mirror
The vehicle may have visor vanity mirrors,
with or without lamps. Lift the mirror cover
to turn the lamps on, if equipped.
