WARNING

■

Precautions regarding the

exhaust pipe

Exhaust gasses cause the

exhaust pipe to become quite hot.

When washing the vehicle, be

careful not to touch the pipe until it

has cooled sufficiently, as touch-

ing a hot exhaust pipe can cause

burns.

■

Precaution regarding the rear

bumper with Blind Spot Moni-

tor (if equipped)

If the paint of the rear bumper is

chipped or scratched, the system

may malfunction. If this occurs,

consult your Toyota dealer.

NOTICE

■

To prevent paint deteriora-

tion and corrosion on the

body and components (alumi-

num wheels, etc.)

●

Wash the vehicle immediately in

the following cases:

• After driving near the sea coast

• After driving on salted roads

• If coal tar or tree sap is present

on the paint surface

• If dead insects, insect droppings

or bird droppings are present on

the paint surface

• After driving in an area contami-

nated with soot, oily smoke,

mine dust, iron powder or chem-

ical substances

• If the vehicle becomes heavily

soiled with dust or mud

• If liquids such as benzene and

gasoline are spilled on the paint

surface

●

If the paint is chipped or

scratched, have it repaired

immediately.

●

To prevent the wheels from cor-

roding, remove any dirt and

store in a place with low humid-

ity when storing the wheels.

■

Cleaning the exterior lights

●

Wash carefully. Do not use

organic substances or scrub

with a hard brush.

This may damage the surfaces

of the lights.

●

Do not apply wax to the sur-

faces of the lights.

Wax may cause damage to the

lenses.

■

To prevent damage to the

windshield wiper arms

When lifting the wiper arms away

from the windshield, pull the driver

side wiper arm upward first, and

repeat for the passenger side.

When returning the wipers to their

original position, do so from the

passenger side first.

■

When using a high pressure

car wash

●

When washing the vehicle, do

not spray the camera or its sur-

rounding area directly with a

high pressure washer. Shock

applied from high pressure

water may cause the device to

not operate normally.

●

Do not bring the nozzle tip close

to boots (rubber or resin manu-

factured cover), connectors or

the following parts. The parts

may be damaged if they come

into contact with high-pressure

water.

• Traction related parts

• Steering parts

• Suspension parts

394

7-1. Maintenance and care



Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.



If dirt cannot be removed,
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.

■

Shampooing the carpets

There are several commercial foam-

ing-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 keeping the carpet 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

excessive wear, fraying or cuts.

NOTICE

• Brake parts

●

and bumpers, may be deformed

and damaged. Also, do not con-

tinuously hold the nozzle in the

same place.

●

Do not spray the lower part of

the windshield continuously. If

water enters the air conditioning

system intake located near the

lower part of the windshield, the

air conditioning system may not

operate correctly.

●

Do not wash the underside of

the vehicle using a high pres-

sure car washer.

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

●

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
