dry the parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Plated portions
If dirt cannot be removed, clean the
parts as follows:
●Use a soft cloth dampened with an
approximately 5% solution of neutral detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to remove any remaining moisture.

Maintenance and care
Remove dirt and dust using a
vacuum cleaner. Wipe dirty sur-
faces with a cloth dampened with
lukewarm water.

off with a soft cloth dampened
with neutral detergent diluted to
approximately 1%.
Wring out any excess water from
the cloth and thoroughly wipe off
remaining traces of detergent
and water.
■Shampooing the carpets
There are several commercial foaming-
type cleaners available. Use a sponge or brush to apply the foam. Rub in over-lapping circles. Do not use water. Wipe
dirty surfaces and let them dry. Excellent results are obtained by keeping the car-pet as dry as possible.
■Handling the seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the belts periodically for exces-
sive wear, fraying or cuts.
■Front side windows with IR protec- tive coating (vehicles with IR pro-tective coating)

■Where to go for maintenance ser-
vice?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service opera- tions as well as other inspections and repairs be carried out by authorized
Toyota retailers or Toyota authorized repairers, or any reliable repairers. For repairs and services covered by your
warranty, please visit an authorized Toyota retailer or repairer, who will use genuine Toyota parts in repairing any
difficulties you may encounter. There can also be advantages in utilizing authorized Toyota retailers or repairers
for non-warranty repairs and services, as members of the Toyota network will be able to expertly assist you with any
difficulties you may encounter.
Your Toyota retailer or Toyota authorized
repairer, or any reliable repairer will per- form all of the scheduled maintenance on your vehicle reliably and economi-
cally due to their experience with Toyota vehicles.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance
schedule.
For full details of your maintenance
schedule, read the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.
What about do-it-yourself mainte-
nance?
Many of the maintenance items are
easy to do yourself if you have a little
mechanical ability and a few basic
automotive tools.
Note, however, that some maintenance
tasks require special tools and skills.
These are best performed by qualified
technicians. Even if you’re an experi-
enced do-it-yourself mechanic, we rec-
ommend that repairs and maintenance
be conducted by any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer. Any authorized
Toyota retailer or repairer will keep a
record of maintenance, which could be
useful should you ever require War-
ranty Service. Should you choose to
select a qualified and equipped profes-
sional other than an authorized Toyota
repairer to service or maintain your
vehicle, we recommend that you

WARNING
■If your vehicle is not properly
maintained
Improper maintenance could result in serious damage to the vehicle and
possible death or serious injury.
■Handling of the 12-volt battery
12-volt battery posts, terminals and related accessories contain lead and

WARNING
The motor 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.
■When working on the motor com-
partment
●Make sure that “POWER ON” on the multi-information display and
the “READY” indicator are both off.
●Keep hands, clothing and tools
away from the moving fan.
●Be careful not to touch the motor,
power control unit, radiator, etc., right after driving as they may be hot. Coolant and other fluids may
also be hot.
●Do not leave anything that may
burn easily, such as paper and rags, in the motor compartment.
●Do not smoke, cause sparks or expose an open flame to the 12-volt battery. 12-volt battery fumes are
flammable.
●Be extremely cautious when work-
ing on the 12-volt battery. It con- tains poisonous and corrosive sulfuric acid.
●Never touch, disassemble, remove or replace the high voltage parts,
cables and their connectors. It can cause severe burns or electric shock that may result in death or
serious injury.
●Take care because brake fluid can
harm your hands or eyes and dam- age painted surfaces. If fluid gets on your hands or in your eyes, flush
the affected area with clean water immediately. If you still experience discomfort, consult a doctor.
■When working near the electric cooling fan or radiator grille
Be sure the power switch is OFF.
With the power switch in ON, the electric cooling fan may automatically start to run if the air conditioning is on
and/or the coolant temperature is high. ( P.471)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.,
from getting in your eyes.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill- ing, it may indicate a serious problem.

Reservoir cap
“MAX” line
“MIN” line
If the level is on or below the “MIN” line,
add coolant up to the “MAX” line.
( P.549)
■Coolant selection
Only use “Toyota Super Long Life Cool- ant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35°C [-31°F])
For more details about coolant, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses, power control unit coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer, test the cap and check for leaks in the cooling system.
Check the radiator and condenser
and clear away any foreign objects.
If either of the above parts is
extremely dirty or you are not sure
of their condition, have your vehicle
inspected by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
WARNING
■When the EV system is hot
Do not remove the power control unit
coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if
the cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.

If the level is on or below the “MIN” line,
add coolant up to the “MAX” line.
■Coolant selection
In order to ensure maximum perfor-
mance of the traction battery cooling system and limit risks of battery short-circuit and other damage to your vehi-
cle, Toyota recommends using “Toyota Genuine Traction Battery Coolant” or
similar high-quality ethylene glycol-
based, low electric conductivity coolant, non-amine and non-borate coolant with azole additives.
Toyota cannot guarantee that the use of a product other than “Toyota Genuine Traction Battery Coolant” will prevent
risks of battery short-circuit or other damage.
Never use water as it will cause dam-
age.
Do not reuse coolant that has been removed from the radiator.
For more details about coolant, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■If the coolant level drops within a short time of replenishing
Visually check the hoses, heater coolant
reservoir caps, drain cock and water pump.
If you cannot find a leak, have any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer, test the cap and check for leaks
in the cooling system.
WARNING
■When the electric cooling fan is operating
Do not touch the motor compartment.
With the power switch in ON, the electric cooling fan may automatically
start to run if the air conditioning is on and/or the coolant temperature is high. Be sure the power switch is OFF
when working near the electric cool- ing fan or radiator grille.
