For cool air to be sent to the rear of the vehicle, the
air-conditioning system on the main climate-control
panel must be on. 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.
Passenger Compartment Air Filter
The passenger compartment air filter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/filter, it may need to
be changed periodically. For how often to change the
passenger compartment air filter, see Scheduled
Maintenance on page 6-4.
The access panel for the passenger compartment air
filter is located under the hood near the windshield,
on the passenger’s side of the vehicle.
