6-1. Maintenance and care
●Working from top to bottom, liberally apply water to the vehicl e
body, wheel wells and underside of the vehicle to remove any di rt
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 thoroughl y
with water.
● Wipe away any water.
● Wax the vehicle when the wate rproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of
the vehicle. Make sure to extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle su rface,
parts (wheel, etc.) and harm your vehicle’s paint.
● In certain automatic car washes, the roof antenna (if equipped) or rear
spoiler may interfere with machine operation. This may prevent the vehicle
from being cleaned properly or result in damage to the antenna or rear
spoiler.
■ 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 ar eas continu-
ously.
Cleaning and prot ecting the vehicle
exterior
Perform the following to protect the vehicle and maintain it in
prime condition:

3946-1. Maintenance and care
4RUNNER (U)
NOTICE
■To prevent paint deterioration an d corrosion on the body and compo-
nents (aluminum 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 presen t on the
paint surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron powder or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the pai nt surface
● If the paint is chipped or scratched, have it repaired immediat ely.
● To prevent the wheels from corroding, remove any dirt and store in a place
with low humidity when storing the wheels.
■ Cleaning the exterior lights
● Wash carefully. Do not use organic substances or scrub with a h ard brush.
This may damage the surfaces of the lights.
● Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■ High pressure car washes
● Vehicles with rear view monitor system: When washing the vehicl e, do not
apply intensive bursts of water to the camera or camera area. D oing so
may result in the camera malfunctioning.
● Do not spray water directly on the radar which is equipped behind the
emblem. Otherwise it may cause the device to be damaged.
● Do not bring the nozzle tip close to boots (rubber or resin man ufactured
cover), connectors or the following parts. The parts may be dam aged if
they come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
● Keep the cleaning nozzle at least 11.9 in. (30 cm) away from th e vehicle
body. Otherwise resin section, such as moldings and bumpers, ma y be
deformed and damaged. Also, do not continuously 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 wind-
shield, the air conditioning system may not operate correctly.
● Do not wash the underside of the vehicle using a high pressure car
washer.

4406-3. Do-it-yourself maintenance
4RUNNER (U)
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warn ing
valves and transmitters that allow the tire pressure warning sy stem to
provide advance warning in the event of a loss in tire inflatio n pressure.
Whenever wheels are replaced, tir e pressure warning valves and trans-
mitters must be installed. ( P. 425)
WARNING
■When replacing wheels
●Do not use wheels that are a different size from those recommen ded in
the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leaking wheel which is designed fo r a
tubeless tire. Doing so may resu lt in an accident, causing death or seri-
ous injury.
■When installing the wheel nuts
Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened, lead-
ing to bolt or disc wheel damage. In addition, the oil or greas e can cause the
wheel nuts to loosen and the wheel may fall off, causing an accident and
resulting in death or serious injury. Remove any oil or grease from the wheel
bolts or wheel nuts.
NOTICE
■Replacing tire pressure warn ing valves and transmitters
●Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced b y your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
●Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work prop erly
with non-genuine wheels.
