861-4. Hybrid system
of cooling the hybrid battery
(traction battery).
If the vents are blocked, it may
interfere with the cooling of the
hybrid battery (traction battery).
If input/output of the hybrid battery
(traction battery) becomes limited
and the distance that the vehicle
can be driven using the electric
motor (traction motor) is reduced,
the fuel economy 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,
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
NOTICE
■Hybrid battery (traction bat-
tery) air intake vents
●Make sure not to block the air
intake vents with anything, such
as a seat cover, plastic cover, or
luggage. The input/output of the
hybrid battery (traction battery)
may be restricted, leading to a
reduction in hybrid battery (trac-
tion battery) output and a mal-
function.
●Periodically clean the air intake
vents to prevent them from clog-
ging. ( P.440)
●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).
