902-1. Plug-in hybrid system
WARNING
●Carefully inspect the ground
under the vehicle. If you find
that liquid has leaked onto the
ground, the fuel system may
have been damaged. Leave the
vehicle as soon as possible.
■Hybrid battery (traction bat-
tery)
●Your vehicle contains a sealed
lithium-ion battery.
●Never resell, hand over or mod-
ify the hybrid battery. To prevent
accidents, hybrid batteries that
have been removed from a dis-
posed vehicle are collected
through Toyota dealer. Do not
dispose of the battery yourself.
Unless the battery is properly
collected, the following may
occur, resulting in death or seri-
ous injury:
• The hybrid battery may be ille- gally disposed of or dumped,
and it is hazardous to the envi-
ronment or someone may touch
a high voltage part, resulting in
an electric shock.
• The hybrid battery is intended to be used exclusively with your
hybrid vehicle. If the hybrid bat-
tery is used outside of your
vehicle or modifi ed in any way,
accidents such as electric
shock, heat generation, smoke
generation, an explosion and
electrolyte leakage may occur.
When reselling or handing over
your vehicle, the possibility of
an accident is extremely high
because the person receiving
the vehicle may not be aware of
these dangers.
●If your vehicle is disposed of
without the hybrid battery hav-
ing been removed, there is a
danger of serious electric shock
if high voltage parts, cables and
their connectors are touched. In
the event that your vehicle must
be disposed of, the hybrid bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the hybrid bat-
tery is not disposed of properly,
it may cause electric shock that
can result in dea th or serious
injury.
■Caution while driving
If the vehicle under floor area
receives strong shock or impact
while driving, stop the vehicle in a
safe area and check around the
bottom of the vehicle. If there is
damage to the hybrid battery
(traction battery) or liquid leakage,
it may lead to a vehicle fire, etc.
Do not touch the vehicle and
immediately contact your Toyota
dealer.
■Modifications
Do not modify the vehicle to make
the height lower.
It is easier for the hybrid battery
(traction battery) in the under floor
area to come in contact with the
ground when the vehicle is low-
ered. If the hybrid battery (traction
battery) is damaged, a vehicle fire
may occur which could lead to
death or serious injury.

■Cautions during setting up
the display
As the hybrid system needs to be
operating during setting up the
display, ensure that the vehicle is
parked in a place with adequate
ventilation. In a closed area such
as a garage, exhaust gases
including harmful carbon monox-
ide (CO) may collect and enter
the vehicle. This may lead to
death or a seri ous health hazard.
NOTICE

Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the specified size.
●Maintain the recommended
level of air pressure.
●Do not drive in excess of 75
mph (120 km/h), regardless of
the type of snow tires being
used.
●Use snow tires on all, not just
some wheels.
■Driving with tire chains
(except 235/55R19 tires)
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in the
vehicle being unable to be driven
safely, and may cause death or
serious injury.
●Do not drive in excess of the
speed limit specifi ed for the tire
chains being used, or 30 mph
(50 km/h), whichever is lower.
●Avoid driving on bumpy road
surfaces or over potholes.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
●Slow down sufficiently before
entering a curve to ensure that
vehicle control is maintained.
●Do not use LTA (Lane Tracing
Assist) system.

WARNING
■Off-road driving precautions
Always observe the following pre-
cautions to minimize the risk of
death, serious injury or damage to
your vehicle:
●Drive carefully when off the
road. Do not take unnecessary
risks by driving in dangerous
places.
●Do not grip the steering wheel
spokes when driving off-road. A
bad bump could jerk the wheel
and injure your hands. Keep
both hands and especially your
thumbs on the outside of the
rim.
●Always check your brakes for
effectiveness immediately after
driving in sand, mud, water or
snow.
●After driving through tall grass,
mud, rock, sand, rivers, etc.,
check that there is no grass,
bush, paper, rags, stone, sand,
etc. adhering or trapped on the
underbody. Clear off any such
matter from the u nderbody. If
the vehicle is used with these
materials trapped or adhering to
the underbody, a breakdown or
fire could occur.
●When driving off-road or in rug-
ged terrain, do not drive at
excessive speeds, jump, make
sharp turns, strike objects, etc.
This may cause loss of control
or vehicle rollover causing
death or serious injury. You are
also risking expensive damage
to your vehicle’s suspension
and chassis.
NOTICE
■To prevent the water damage
Take all necessary safety mea-
sures to ensure that water dam-
age to the hybrid b attery (traction
battery), hybrid system or other
components does not occur.
●Water entering th e engine com-
partment may cause severe
damage to the hybrid system.
●Water entering the hybrid trans-
mission will cause deterioration
in transmission quality. The
malfunction indicator may come
on, and the vehicle may not be
drivable.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the hybrid
transaxle case, reducing the
gear oil’s lubricating qualities.
■When you drive through
water
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of t he riverbed for
firmness. Drive s lowly and avoid
deep water.

WARNING
■Cautions for using “My Room
Mode”
Do not leave children, people who
need assistance, or pets inside
the vehicle. The system may turn
off automatically and the interior
temperature may become high or
low, resulting in heat stroke, dehy-
dration or hypothermia. Failure to
do so may result in death or seri-
ous injury.
■To prevent the windshield
from fogging up
Do not use the windshield defog-
ger switch during cool air opera-
tion in extremely humid weather.
The difference between the tem-
perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.
■When the outside rear view
mirror defoggers are operat-
ing
Do not touch the rear view mirror
surfaces when the outside rear
view mirror def oggers are on.
NOTICE
■To prevent 12-volt battery dis-
charge
Do not leave the air conditioning
system on longer than necessary
when the hybrid system is off.
■When repairing/replacing
parts of the air conditioning
system
Have repair/replacement per-
formed by your To yota dealer.
When a part of the air condition-
ing system, such as the evapora-
tor, is to be repl aced, it must be
replaced with a new one.
