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 REAR CNTL to allow a rear seat
passenger to 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 REAR CNTL.
Turn the center knob clockwise or counterclockwise
to change the direction of the airflow in the rear
seating area.To change the current mode, select one of the following:
H(Vent):Use this mode to direct air to the upper
outlets, with a little air directed to the floor outlets.
2(Floor):Use this mode to direct most of the air to
the floor outlets.
9(Fan):Turn the left knob clockwise or
counterclockwise to HIGH, MED (Medium) or LOW to
increase or decrease the fan speed in the rear-seating
area. Turn the knob to OFF to turn off the fan.
Temperature Control:To increase or decrease the
temperature for the rear of the vehicle, turn the
right knob located on the climate-control panel.
The air-conditioning system on the main climate control
panel must be turned on to direct cooled air to the rear of
the vehicle. If it is not on, then the temperature in the rear
of the vehicle will remain at cabin temperature.
Be sure to keep the area under the front seats clear of
any objects so that the air inside of your vehicle can
circulate effectively.
For information on how to use the main climate control
system, seeClimate Control System on page 3-18.
For information on ventilation, seeOutlet Adjustment on
page 3-20. Rear Climate Control Panel

your vehicle needs service. If the regular brake
system warning light isn’t on, you still have brakes,
but you don’t have anti-lock brakes. If the regular
brake system warning light is also on, you don’t have
anti-lock brakes and there’s a problem with your regular
brakes. SeeBrake System Warning Light on page 3-33
for more information.

on briefly when you turn the ignition key to RUN.
