■Front passenger occupant
classification system precau-
tions
Observe the following precautions
regarding the front passenger
occupant classification system.
Failure to do so may cause death
or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s
seat belt plate has not been left
inserted into the buckle before
someone sits in the front pas-
senger seat.
●Make sure the “PASS AIR BAG
OFF” indicator light is not illumi-
nated when using the seat belt
extender for the front passenger
seat. If the “PASS AIR BAG
OFF” indicator light is illumi-
nated, disconnect the extender
tongue from th e seat belt
buckle, and reconnect the seat
belt. Reconnect the seat belt
extender after making sure the
“PASS AIR BAG ON” indicator
light is illuminated. If you use
the seat belt extender while the
“PASS AIR BAG OFF” indicator
light is illuminated, the SRS air-
bags for the front passenger will
not activate, which could cause
death or serious injury in the
event of a collision.
●Do not apply a heavy load to the
front passenger seat or equip-
ment (e.g. seatback pocket).
●Do not put weigh t on the front
passenger seat by putting your
hands or feet on the front pas-
senger seat seatback from the
rear passenger seat.
●Do not let a rea r passenger lift
the front passenger seat with
their feet or press on the seat-
back with their legs.
●Do not put objects under the
front passenger seat.

●Do not recline the front passen-
ger seatback so far that it
touches a rear seat. This may
cause the “PASS AIR BAG
OFF” indicator lig ht to be illumi-
nated, which indicates that the
SRS airbags for the front pas-
senger will not act ivate in the
event of a severe accident. If
the seatback touches the rear
seat, return the seatback to a
position where it does not touch
the rear seat. Keep the front
passenger seatback as upright
as possible when the vehicle is
moving. Reclining the seatback
excessively may lessen the
effectiveness o f the seat belt
system.
●If an adult sits in the front pas-
senger seat, the “PASS AIR
BAG ON” indicator light is illumi-
nated. If the “PASS AIR BAG
OFF” indicator is illuminated,
ask the passen ger to sit up
straight, well back in the seat,
feet on the floor, and with the
seat belt worn correctly. If the
“PASS AIR BAG OFF” indicator
still remains illuminated, either
ask the passenger to move to
the rear seat, or if that is not
possible, move the front pas-
senger seat fully rearward.
●When it is unavoidable to install
a forward-facing child restraint
system on the fr ont passenger
seat, install the child restraint
system on the fr ont passenger
seat in the proper order.
(
P. 5 2 )
●Do not modify or remove the
front seats.
●Do not kick the front passenger
seat or subject it to severe
impact. Otherwise, the SRS
warning light m ay come on to
indicate a malfu nction of the
front passenger occupant clas-
sification system. In this case,
contact your Toyota dealer
immediately.
●Child restraint systems installed
on the rear seat should not con-
tact the fron t seatbacks.
●Do not use a seat accessory,
such as a cushion and seat
cover, that covers the seat
cushion surface.
●Do not modify or replace the
upholstery of the front seat.

■Unoccupied
■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller
adult sits in the front passenger seat, the system may not recognize
him/her as an adult depending on his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenge r does not wear a seat belt.
*4: For some children, child in seat, child in booster seat or chi ld in convert-
ible seat, the system may not recognize him/her as a child. Fac tors
which may affect this can be the physique or posture.
*5: Never install a rear-facing ch ild restraint system on the front passenger
seat. A forward-facing child restraint system should only be in stalled on
the front passenger sea t when it is unavoidable. ( P.50)
*6: In case the indicator light is not illuminated, consult this m anual on how
to install the child restr aint system properly. (P. 5 2 )

■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.463)
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 2.9 gal.
Hybrid system precautions
Take care when handling the hybrid system, as it is a high
voltage system (about 650 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.

HIGHLANDER 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. (
P.470)
■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
●Do not place objects that will
block the air intake vents. The
hybrid battery (traction battery)
may become limited and be
damaged.
●Clean the air intake/discharge
vents regularly to prevent the
hybrid battery (traction battery)
to be limited.
●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. Wh en the filter
remains noticeably dirty even
after cleaning the air intake
vent, filter cleaning or replace-
ment is recommended. Refer to
P.435for details on how to clean
the filters.
