maximum air conditioning
performance.
. Clear away any ice, snow or
leaves from the air inlets at the
base of the windshield that may
block the flow of air into the
vehicle.

hood deflectors may adversely
affect the performance of the
system.
. Keep the path under the front
seats clear of objects to help
circulate the air inside of the
