Hybrid battery air vent
Hybrid battery air vent
There is an air intake vent on the
side of the rear right seatback for
the purpose of cooling the hybrid
battery (traction battery). If the
vent becomes blocked, the hybrid
battery may overheat, leading to
a reduction in hybrid battery out-
put.
Emergency shut off system
The emergency shut off system blocks off the high voltage current
and stops the fuel pump to minimize the risk of electrocution and fuel
leakage when a certain level of impact is detected by the impact sen-
sor. If the emergency shut off syste m activates, your vehicle will not
restart. To restart the hybrid system, contact your Toyota dealer.
Energy monitor/consumption screen
