Dust and Pollen Filter *
The heating and cooling system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance Minder TM
messages will let
you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1Dust and Pollen Filter
If the airflow from the heating and cooling system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.

Handling the Unexpected
■ Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the high temperature
indicator goes off.
uIf the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
uIf the coolant level in the reserve tank is
low, add coolant until it reaches the MAX mark.
uIf there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.
■ Last thing to do
Once the engine has cooled sufficiently, restart it and check the high temperature indicator.
If the high temperature indicator is off, resume driving. If it stays on, contact a dealer for repairs.
1How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
3WARNING
Removing the radiator cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the radiator cap.
