If the wiper switch is in “AUTO”, the wip- 
ers may operate unexpectedly in the fol- 
lowing situations, and may result in
hands being caught or other serious 
injuries and cause damage to the wiper 
blades.

Maintenance and care
■Caring for leather areas 
Toyota recommends cleaning the interior of the vehicle at least twice a year to 
maintain the quality of the vehicle’s interior. 
■ Shampooing the carpets 
There are several commercial foaming-type cleaners available. Use a sponge 
or brush to apply the foam. Rub in overlapping circles. Do not use water. 
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep- 
ing the carpet as dry as possible. 
■ Seat belts 
Clean with mild soap and lukewarm water using a cloth or sponge. Also 
check the belts periodically for excessive wear, fraying or cuts.
WARNING
■ Water in the vehicle 
● Do not splash or spill liquid in the vehicle, such as on the floor, in the 
hybrid battery (traction battery) air vents, and in the luggage compartment. 
Doing so may cause the hybrid battery, electrical components, etc. to mal-
function or catch fire. 
● Do not get any of the SRS components or wiring in the vehicle interior wet.  
( P. 39) 
An electrical malfunction may cause the airbags to deploy or not function 
properly, resulting in death or serious injury. 
■ Cleaning the interior (especially instrument panel) 
Do not use polish wax or polish cleaner. The instrument panel may reflect 
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.

NOTICE
■Cleaning detergents 
● Do not use the following types of detergent, as they may discolor the vehi- 
cle interior or cause streaks or damage to painted surfaces: 
• Non-seat portions: Organic substances such as benzene or gasoline, 
alkaline or acidic solutions, dye, and bleach 
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alco-
hol 
● Do not use polish wax or polish cleaner. The instrument panel’s or other 
interior part’s painted surface may be damaged. 
■ Preventing damage to leather surfaces 
Observe the following precautions to avoid damage to and deterioration of

stery, as they may stick to the leather surface if the vehicle interior heats 
up significantly. 
■ Water on the floor 
Do not wash the vehicle floor with water. 
Vehicle systems such as the audio system may be damaged if water comes 
into contact with electrical components such as the audio system above or 
under the floor of the vehicle. Water may also cause the body to rust.

7-2. Maintenance
■Scheduled maintenance 
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”. 
■Do-it-yourself maintenance 
What about do-it-y ourself maintenance?
Many 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 experienced do-it-yourself mechanic, we recommend that repairs 
and maintenance be conducted by any authorized Toyota dealer or 
repairer, or another duly qualified and equipped professional. Any
authorized Toyota dealer or repairer will keep a record of maintenance, 
which could be useful should you ever require Warranty Service. Should 
you choose to select a qualified and equipped professional other than
an authorized Toyota repairer to service or maintain your vehicle, we 
recommend that you request that a record of maintenance be kept.
Maintenance requirements
To ensure safe and economical driv ing, day-to-day care and reg- 
ular maintenance is essential. Toyota recommends the following

■Where to go for maintenance service? 
In order to maintain your vehicle in the best possible condition, Toyota recom- 
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Toyota dealers or repairers or other duly 
qualified and equipped professionals. For repairs and services covered by 
your warranty, please visit an authorized Toyota dealer or repairer, who will
use genuine Toyota parts in repairing any difficulties you may encounter. 
There can also be advantages in utilizing authorized Toyota dealers or repair- 
ers 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 dealer or repairer, or another duly qualified and equipped profes- 
sional will perform all of the scheduled maintenance on your vehicle reliably
and economically due to their experience with Toyota vehicles. 
■ Does your vehicle need repair? 
Be on the alert for changes in performance and sounds, and visual tip-offs 
that indicate service is needed. Some important clues are: 
● Engine missing, stumbling, or pinging 
● Appreciable loss of power 
● Strange engine noises 
● A fluid leak under the vehicle (However, water dripping from the air condi- 
tioning after use is normal.) 
● Change in exhaust sound (This may indicate a dangerous carbon monoxide 
leak. Drive with the windows open and have the exhaust system checked
immediately.) 
● Flat-looking tires, excessive tire squeal when cornering, uneven tire wear 
● Vehicle pulls to one side when driving straight on a level road 
● Strange noises related to suspension movement 
● Loss of brake effectiveness, spongy feeling brake pedal, pedal almost 
touches the floor, vehicle pulls to one side when braking 
● Engine coolant temperature continually higher than normal 
If you notice any of these clues, take your vehicle to any authorized Toyota 
dealer or repairer, or another duly qualified and equipped professional, as
soon as possible. Your vehicle may need adjustment or repair.

Maintenance and care
WARNING
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. 
■ When working on the engine compartment 
● Make sure that the “Power 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, radiator, 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 compartment. 
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes 
are flammable. 
● Take care because brake fluid can harm your hands or eyes and damage 
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 fans or radiator grille 
Be sure the power switch is off. 
With the power switch in ON mode, the electric cooling fans may automati- 
cally start to run if the air conditioning is on and/or the coolant temperature 
is high. ( P. 432) 
■ 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 air cleaner filter removed may cause excessive engine wear 
due to dirt in the air. 
■ 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 refilling, it may indicate a serious problem.
