(traction battery). If charging/discharging of the hybrid batte ry (traction bat-
tery) becomes limited, the distance that the vehicle can be dri ven using the
electric motor (traction motor) may be reduced and the fuel eco nomy may
be reduced. Inspect and clean the air intake vent periodically.
● Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter , contact any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
