Q Scheduled maintenance of the air
intake vent is necessary when
In some situations such as when the vehicle
is used frequently or in heavy traffic or dusty
areas, the air intake vent may need to be
cleaned more regularly. For details, refer to
“Lexus Service Booklet” or “Lexus War-
ranty Booklet”.
Q Cleaning the air intake vent
O Dust in the air intake vent may interfere
with the cooling of the hybrid battery
(traction battery). If charging/discharg-
ing of the hybrid battery (traction battery)
becomes limited, the distance that the
vehicle can be driven using the electric
motor (traction motor) may be reduced
and the fuel economy may be reduced.
Inspect and clean the air intake vent peri-
odically.
O Improper handling of the air intake vent
cover and filter may result in damage to
them. If you have any concerns about
cleaning the filter, contact any authorized
Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
Q If “Maintenance required for Traction
battery cooling parts See owner’s man-
ual” is displayed on the multi-informa-
tion display
O If this warning message is displayed on
the multi-information display, remove the
air intake vent cover and clean the filter.
(P.385)
O After cleaning the air intake vent, start
the hybrid system and check that the
warning message is no longer displayed.
After the hybrid system is started, it may
be necessary to drive the vehicle up to
approximately 20 minutes before the
warning message disappears. If the warn-
ing message does not disappear after
driving for appropriately 20 minutes,
have the vehicle inspected by any autho-
rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
Q When cleaning the air intake vent
O Do not use water or other liquids to
clean the air intake vent. If water is
applied to the hybrid battery (traction
battery) or other components, a mal-
function or fire may occur.
O Before cleaning the air intake vent,
make sure to turn the power switch off
to stop the hybrid system.
Q When removing the air intake vent
cover
Do not touch the service plug located
near the air intake vent. (P.82)
