The air conditioning filter may clog af-
ter long use. The filter may need to be
cleaned or replaced if the air flow of
the air conditioning and heater experi-
ences extreme reductions in operating
efficiency, or if the windows begin to
fog up easily.
To maintain the air conditioning efficiency,
inspect, clean and replace the air condi-
tioning filter according to the maintenance
schedule. In dusty areas or areas with
heavy traffic flow, such as inner city or
desert areas, more frequent cleaning or
early replacement may be required. (For
scheduled maintenance information, please
refer to the “Scheduled Maintenance
Guide” or “Owner ’s Manual Supplement”.)

in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
NOTICE
Remember that battery and ignition
cables carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.
 Add only “Toyota Super Long Life
Coolant” or similar high quality eth-
ylene glycol based nonsilicate,
nonamine, nonnitrite, and nonbo-
rate coolant with longlife hybrid
organic acid technology to fill the
radiator. “Toyota Super Long Life
Coolant” is a mixture of 50% cool-
ant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45%
deionized water (for Canada).
If you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging the parts
or paint.
 Do not allow dirt or anything else
to fall through the spark plug holes.
 Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
 Do not reuse iridiumtipped spark
plugs by cleaning or regapping.
 Do not overfill automatic transmis-
sion fluid, or the transmission
could be damaged.
 Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
 Be careful not to scratch the glass
surface with the wiper frame.

check to see that you have not for-
gotten any tools, rags, etc.
