7-1.Mainte nance a nd care
Working from top to bottom, lib-
erally apply water to the vehicle
body, wheel wells and underside
of the vehicle to remove any dirt
and dust.
 Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
 For hard-to-remove marks, use
car wash soap and rinse thor-
oughly with water.
 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean sur-
face, apply wax when the vehicle body
is cool.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface scratches caused in a car wash, etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the
plant.
●The restoration time differs depending
on the depth of the scratch and out- side temperature. The restoration time may become shorter when the coating
is warmed by applying warm water.
●Deep scratches caused by keys,
coins, etc., cannot be restored.
●Do not use wax that contain abra- sives.
■Automatic car washes
●Before washing the vehicle:• Fold the mirrors
• Turn off the power back door (if equipped)
Start washing from the front of the vehi-
cle. Extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle sur-face, parts (wheel, etc.) and harm
your vehicle’s paint.
●Rear spoiler (if equipped) may not be
washable in some automatic car washes. There may also be an increased risk of damage to vehicle.
●When the shift position needs to be held in N, refer to P.251.
■High pressure car washes
As water may enter the cabin, do not bring the nozzle tip near the gaps around the doors or perimeter of the
windows, or spray these areas continu- ously.
■Note for a smart entry & start sys-tem
●If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the following correction procedures to
wash the vehicle: • Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-sav- ing mode to disable the smart entry & start system ( P.204)
●If the electronic key is inside the vehi- cle and a door handle becomes wet
during a car wash, a buzzer may sound outside the vehicle and “Key Detected In Vehicle” may be shown

Maintenance and care
Remove dirt and dust using a
vacuum cleaner. Wipe dirty sur-
faces with a cloth dampened with
lukewarm water.
 If dirt cannot be removed, wipe it
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

■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
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.

■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
