2021 TOYOTA SIENNA HYBRID fuel

861-4. Hybrid system
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
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. If the vents become
blocked, the hybrid battery
(traction battery) input and out-
put may be restricted, leading to
a reduction in hybrid battery
(traction battery) output and a
malfunction.
●When dust etc. has accumu-
lated in the air intake vents,
clean them with a vacuum
cleaner to prevent the vents
from clogging.
●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).
●Do not carry large amounts of
water such as water cooler bot-
tles in the vehicle. If water spills
onto the hybrid battery (traction
battery), the battery may be
damaged. Have the vehicle
inspected by your Toyota
dealer.
●There are filters installed to the
air intake vents. When the filters
remain noticeably dirty even
after cleaning the air intake
vents, filters cleaning or
replacement is recommended.
For information regarding filters
cleaning or replacement, refer
to P.444.
●If “Maintenance Required for
Traction Battery Cooling Parts
See Owner’s Manual” is shown
on the multi-information dis-
play, the air intake vents and fil-
ters may be clogged. Refer to
P.443for information on how to
clean the air intake vents.
