■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at
least enough gasoline to make the
low fuel level warning light ( P.481)
go off. If there is only a small amount of fuel, the hybrid system
may not be able to
start. (The stan-
dard amount of fuel is about 2.0 gal.
[7.6 L, 1.7 I mp. gal.] when the vehi-
cle is on a level surface. This value
may vary when the v ehicle is on a
slope. Add extra fu el when the vehi-
cle is inclined.)
Hybrid system precautions
Take care when handling the hybrid system, as it is a high
voltage system (about 600 V at maximum) as well as contains
parts that become extremely hot when the hybrid system is
operating. Obey the warning labels attached to the vehicle.
System components

871-4. Hybrid system
COROLLA HV_U

For safety and security
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
●A filter is installed to the air
intake vent. Wh en the filter
remains noticeably dirty even
after cleaning the air intake
vent, filter cleaning or replace-
ment is recommended. Refer to
P.455 for details on how to clean
the filters.
