For safety and security
There are the air intake vents
both sides of the behind the sec-
ond seat for the purpose of cool-
ing the hybrid battery (traction
battery). If the vents becomes
blocked, the hybrid battery (trac-
tion battery) input and output
may be reduced. When a certain level of impact is
detected by the impact sensor,
the emergency shut off system
blocks the high voltage current
and stops the fuel pump to mini-
mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates,
your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the hybrid system or
an improper operation is
attempted.
If a warning message is shown
on the multi-information display,

NOTICE
■Hybrid battery (traction bat-
tery) air intake vents
●Make sure that the air intake
vents are not blocked, such as
by a seat cover, plastic cover, or
luggage. If the vents are
blocked, the hybrid battery
(traction battery) input and out-
put may be restricted, possibly
leading to a malfunction.
●Clean the air intake vents regu-
larly to prevent the hybrid bat-
tery (traction b attery) from
overheating.
●Do not get water or foreign
materials in the air intake vents
as this may cause a short circuit
and damage the hybrid battery
(traction battery).
●A filter is installed to the air
intake vents. When the filter
remains noticeably dirty even
after cleaning the air intake
vents, filter cleaning or replace-
ment is recommended. Refer to
P.489 for details on how to

hybrid battery (traction battery). If
charging/discharging of the hybrid
battery (traction battery) becomes
limited, the distance that the vehi-
cle 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 periodically.
●Improper handling of the air intake
vent cover and filt er may result in
damage to them. If you have any
concerns about cleaning the filter,
contact your Toyota dealer.
