Slide and pull out the filter. Replace it
with a new one.
The “↑UP” marks shown on the filter
should be pointing up.
If the filter is dirty, clean by blowing
compressed air through the filter from
the underside.
Hold the air gun 5 cm (2 in.) from the fil-
ter and blow for approximately 2 min-
utes at 500 kPa (5.0 kgf/cm
2 or bar, 72
psi).
If an air gun is not available, have the fil-
ter cleaned by any authorized Lexus
dealer or repairer, or another duly quali-
fied and equipped professional.
■Checking interval
Inspect, clean and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement may be
required. (For scheduled maintenance informat ion, please refer to the “Lexus Service
Booklet” or “Lexus Warranty Booklet”.)
■If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.

on the reservoir.Reservoir
“FULL” line
“LOW” line
Add coolant if necessary.
Water can be used in an emergency
if coolant is unavailable.
Start the hybrid system and turn the air conditioning system on to check
that the radiator cooling fans operate and to check for coolant leaks from
the radiator or hoses.
The fans operate when the air conditioning system is turned on immediately after a
cold start. Confirm that the fans are operating by checking the fan sound and air
flow. If it is difficult to check these, turn the air conditioning system on and off
repeatedly. (The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the hybrid system immediately and contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
If the fans are operating:

repairer, or another duly qualified and equipped professional.
