781-4. Hybrid system
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.

Interior features
●The windows may fog up if the
recirculated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up
by the vehicle is still drawn into the
vehicle after closing the windows, it
is recommended that the air intake
mode be set to outside air mode and
the fan speed to any setting except
off.
■Outside/recirculated air mode
●Setting to the r ecirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to c ool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restr icted when auto-
matic mode is selected
●To improve air co nditioning perfor-
mance, perform the following
operations:
• Adjust the fan speed
• Turn off Eco drive mode ( P.316)
■When the outside temperature
is low
The dehumidification function may
not operate even when the “A/C”
switch is pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condi-
tioning system to the outside air
mode.
●During use, various odors from inside and outside the vehicle may
enter into and accumulate in the
air conditioning system. This may
then cause odor
to be emitted
from the vents.
●To reduce potential odors from
occurring:
• It is recommended that the air
conditioning system be set to out-
side air mode prior to turning the
vehicle off.
• The start timing of the blower may be delayed for a short period of
time immediately after the air con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.

WA R N I N G
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
ItemsParts and tools■When working on the engine
compartment
●Make sure that the “ACCES-
SORY” or “IGNITION ON” on
the multi-information display
and the “READY” indicator are
both off.
●Keep hands, clothing and tools
away from the moving fan and
engine drive belt.
●Be careful not to touch the
engine, power control unit, radi-
ator, exhaust manifold, etc. right
after driving as they may be hot.
Oil and other fluids may also be
hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●Do not smoke, c ause sparks or
expose an open flame to fuel or
the battery. Fuel and battery
fumes are flammable.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the power switch is off.
With the power switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.414)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the ai r cleaner filter
removed may cause excessive
engine wear due to dirt in the air.

Maintenance and care
Remove the dust from the air
intake vent with a vacuum
cleaner, etc.
Make sure to only use a vacuum to
suck out dust and clogs. Attempting
to blow out dust and clogs using an
airgun, etc. may push it into the air
intake vent. ( P.437)
If dust and clogs cannot be com-
pletely removed with the air
intake vent cover installed,
remove the cover and clean the
filter.
1 Turn the power switch off.
2 Remove the air intake vent
cover.
Pull the cover as shown in the illus-
tration to disengage the 6 claws,
starting from the claw in the upper
right corner and pull the cover
toward the front of the vehicle to
remove it.
3 Remove the air intake vent
filter.
Disengage the claw to remove the
filter from the rear scuff plate.
Cleaning the hybrid
batter y (traction bat-
ter y) air intake vents
and filter
To prevent the fuel economy
from being affected, visually
inspect the hybrid battery
(traction battery) air intake
vents periodically for dust
and clogs. If it is dusty or
clogged or if “Maintenance
Required for Traction Bat-
tery Cooling Parts See
Owner’s Manual” is shown
on the multi-information
display, clean the air intake
vent using the following
procedures:

4Remove the dust and clogs
from the filter using a vacuum
cleaner, etc.
Make sure to also remove the dust
and clogs from the inside of the air
intake vent cover.
5Reinstall the filter to the
cover.
Engage the 3 claw to install the fil-
ter.
Make sure that t he filter is not
crooked or deformed when install-
ing it.
6 Install the air intake vent
cover.
I ns er t t he t ab o f th e co ve r a s sh ow n
in the illustrati on and push the cover to enga
ge the 6 claws.
■Scheduled maintenance of the
air intake vent is necessary
when
In some situations such as when the
vehicle is used frequently or in
heavy traffic or dusty areas, the air
intake vent may need to be cleaned
more regularly. For d etails, refer to
“Scheduled Maintenance Guide”.
■Cleaning the air intake vent
●Dust in the air intake vent may
interfere with the cooling of the
hybrid battery (trac tion battery). If
charging/discharging of the hybrid
battery (traction battery) becomes
limited, the distance that the vehi-
cle can be driven using the electric
motor (traction motor) may be
reduced and the fuel economy
may be reduced. Inspect and
clean the air intake vent periodi-
cally.
●Improper handling of the air intake
vent cover and filt er may result in
damage to them. If you have any
concerns about cleaning the filter,
contact your Toyota dealer.
■If “Maintenance Required for
Traction Battery Cooling Parts
See Owner’s Manual” is shown
on the multi-information display
●If this warning message is shown
on the multi-information display,
remove the air intake vent cover
and clean the filter. ( P.435)
●After cleaning the air intake vent,
start the hybrid system and check

■Oil capacity (Drain and
refillreference
*)
*: The engine oil capacity is a refer-
ence quantity to be used when
changing the engine oil. Warm up
the engine and turn off the hybrid
system, wait more than 5 min-
utes, and check the oil level on
the dipstick.
■Engine oil selection
“Toyota Genuine Motor Oil” is
used in your Toyota vehicle. Use
Toyota approved “Toyota Genu-
ine Motor Oil” or equivalent to
satisfy the following grade and
viscosity. Oil grade: API SN/RC multi-
grade engine oil
Recommended viscosity: SAE
0W-16
Outside temperature
SAE 0W-16 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-16 is not available,
SAE 0W-20 oil may be used.
However, it must be replaced
