6-3. Do-it-yourself maintenance
Q When cleaning the air intake vent
When cleaning the air intake vent, make
sure to only use a vacuum to suck out
dust and clogs. If a compressed air blow
gun, etc. is used to blow out dust and
clogs, the dust or clogs may be pushed
into the air intake vent, which may affect
the performance of the hybrid battery
(traction battery) and cause a malfunc-
tion.
Q To prevent damage to the vehicle
O Do not allow water or foreign matter
to enter the air intake vent when the
cover is removed.
O Carefully handle the removed filter so
that it will not be damaged.
If the filter is damaged, have it
replaced with a new filter by any
authorized Lexus retailer or Lexus
authorized repairer, or any reliable
repairer.
O Make sure to reinstall the filter and
cover to their original positions after
cleaning.
O Do not install anything to the air intake
vent other than the exclusive filter for
this vehicle or use the vehicle without
the filter installed.
Q If “Maintenance required for Trac-
tion battery cooling parts See
owner’s manual” is displayed on the
multi-information display
If the vehicle is continuously driven with
the warning message (indicating that
charging/discharging of the hybrid bat-
tery (traction battery) may become lim-
ited) displayed, the hybrid battery
(traction battery) may malfunction. If the
warning message is displayed, clean the
air intake vent immediately.
