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
