1-4. Hybrid system
COROLLA HV_U
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,
read the message and follow the
instructions.
■
If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
The hybrid system may not start. In
this case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
NOTICE
■
Hybrid battery (traction bat-
tery) air intake vent
●
Make sure that the air intake
vent is not blocked, such as by
a seat cover, plastic cover, or
luggage. If the vent is blocked,
charging/discharging of the
hybrid battery (traction battery)
may become limited, possibly
leading to a malfunction.
●
Clean the air intake vent regu-
larly to prevent the hybrid bat-
tery (traction battery) from
overheating.
●
Do not allow liquid or foreign
material to enter the air intake
vent as this may cause a short
circuit and damage the hybrid
battery (traction battery).
●
A filter is installed to the air
intake vent. When the filter
remains noticeably dirty even
after cleaning the air intake
vent, filter cleaning or replace-
ment is recommended. Refer to
P.427 for details on how to clean
the filters.
