Enhanced Technology Glass
Your 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, seat
belts must still be worn at all times. For passenger vans,
use only ETG glass approved for your vehicle for
replacement when damaged.
The following table shows laminated glass location,
based on vehicle model and options.

Sun Visors
To block out glare, swing down the sun visors. You can
also swing them to the side.
Visor Vanity Mirror
You may have visor vanity mirrors, with or without
lamps. Lift the mirror cover to turn the lamps on, if you
have them.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.

Rear Air Conditioning and Heating
System
Your vehicle may have a rear heating and
air-conditioning system. This system regulates the
temperature, the fan speed and the air delivery for
the rear-seat passengers only. It also works with
the main climate-control system in your vehicle.
Use this control panel when you would like to maintain
a separate temperature setting. Adjust the direction
of the airflow or adjust the fan speed for the rear seat
passenger(s).If your vehicle has a 135 inch (343 cm) wheelbase,
a rear control panel for this system is located in
the second row behind the driver in the rear of your
vehicle. A rear seat passenger can use this control panel
to personally adjust the temperature, the direction of
the airflow and the fan speed for the rear seating area.
The fan knob located on the front climate control
panel must be turned to AUX (Auxiliary) to let a rear
seat passenger use the control panel in the rear seating
area. Performing this action disables the front control
panel. To return control to this panel, move the fan knob
out of AUX.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the
fan speed in the rear-seating area.
9:This position turns the system off. Front Climate Control Panel
