An electrical malfunction may

cause the airbags to deploy or

not function properly, resulting

in death or serious injury.

●

Vehicles with wireless charger:

Do not let the wireless charger

(

P.398) get wet. Failure to do

so may cause the charger to

become hot and cause burns or

could cause electric shock

resulting in death or serious

injury.

■

Cleaning the interior (espe-

cially 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 dis-

color the vehicle interior or

cause streaks or damage to

painted surfaces:

• Areas other than the seats and

steering wheel: Organic sub-

stances such as benzene or

gasoline, alkaline or acidic solu-

tions, dye, and bleach

• Seats: Alkaline or acidic solu-

tions, such as thinner, benzene,

and alcohol

• Steering wheel: Organic sub-

stances, such as thinner, and

cleaner that contains alcohol

●

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 deteriora-

tion of leather surfaces:

●

Remove any dust or dirt from

leather surfaces immediately.

●

Do not expose the vehicle to

direct sunlight for extended peri-

ods of time. Park the vehicle in

the shade, especially during

summer.

●

Do not place items made of

vinyl, plastic, or containing wax

on the upholstery, as they may

stick to the leather surface if the

vehicle interior heats up signifi-

cantly.

■

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.

■

7-1. Maintenance and care



Remove dirt using a
water-dampened soft cloth or
synthetic chamois.



Wipe the surface with a dry,
soft cloth to remove any
remaining moisture.

■

Cleaning the areas with

satin-finish metal accents

The metal areas use a layer of real

metal for the surface. It is necessary

to clean them regularly. If dirty areas

are left uncleaned for long periods

of time, they may be difficult to

clean.



Remove dirt and dust using a
vacuum cleaner.



Wipe off any excess dirt and
dust with a soft cloth damp-
ened with diluted detergent.

Use a diluted water solution of
approximately 5% neutral wool
detergent.



Wring out any excess water
from the cloth and thoroughly
wipe off all remaining traces
of detergent.



Wipe the surface with a dry,
soft cloth to remove any
remaining moisture. Allow the
leather to dry in a shaded and
ventilated area.

■

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.



Remove dirt and dust using a
vacuum cleaner.



Wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.



Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.

NOTICE

■

Cleaning the inside of the rear

window

●

Do not use glass cleaner to

clean the rear window, as this

may cause damage to the rear

window defogger heater wires

or antenna. Use a cloth damp-

ened with lukewarm water to

gently wipe the window clean.

Wipe the window in strokes run-

ning parallel to the heater wires

or antenna.

Repair and replacement

It is recommended that genuine

Toyota parts be used for repairs to

ensure performance of each sys-

tem. If non-Toyota parts are used in

replacement or if a repair shop other

than a Toyota dealer performs

repairs, confirm the warranty cover-

age.

■

Allow inspection and repairs to

be performed by a Toyota

dealer

●

Toyota technicians are

well-trained specialists and are

kept up to date with the latest ser-

vice information. They are well

informed about the operation of all

systems on your vehicle.

●

Keep a copy of the repair order. It

proves that the maintenance that

has been performed is under war-

ranty coverage. If any problem

should arise while your vehicle is

under warranty, your Toyota

dealer will promptly take care of it.

General maintenance should be
performed on a daily basis. This
can be done by yourself or by a
Toyota dealer.

Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.

For details about maintenance
items and schedules, refer to the
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.

Maintenance require-

ments

constituents, and a wide variety

of automobile components con-

tain or emit chemicals known to

the State of California to cause

cancer and birth defects and

other reproductive harm. Work

in a well ventilated area.

●

Oils, fuels and fluids contained

in vehicles as well as waste pro-

duced by component wear con-

tain or emit chemicals known to

the State of California to cause

cancer and birth defects or

other reproductive harm. Avoid

exposure and wash any

affected area immediately.

●

12-volt battery posts, terminals

and related accessories con-

tain lead and lead compounds

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 “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 fans.

Items

Parts and tools

●

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, cause sparks or

expose an open flame to fuel or

the 12-volt battery. Fuel and

12-volt battery fumes are flam-

mable.

●

Be extremely cautious when

working on the 12-volt battery. It

contains poisonous and corro-

sive sulfuric acid.

■

When working near the elec-

tric cooling fans or radiator

grille

Be sure the power switch is OFF.

With the power switch in ON, the

electric cooling fans may auto-

matically start to run if the air con-

ditioning is on and/or the coolant

temperature is high. (

■

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.
