4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
Perform the following to protect the vehicle and maintain it in prime
condition.
● Working from top to bottom, liber ally 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 cham-
ois.
● For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
● Wipe away any water.
● Wax the vehicle when the waterproof 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 back before washing the vehicle.
● Brushes used in automatic car washes may scratch the vehicle surface
and harm your vehicle’s paint.
■ High pressure car washes
Do not allow the nozzles of the car wash to come within close proximity \
of
the windows. Before car wash, check that the fuel filler door is closed.
■ Aluminum wheels
Remove any dirt immediately by using a neutral detergent. Do not use hard
brushes or abrasive cleaners. Do not use strong or harsh chemical cleaners.
Use the same mild detergent and wax as used on the paint.
■ Bumpers and side moldings
Do not scrub with abrasive cleaners.
■ To prevent paint deterioratio n and corrosion on the body
● Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If you see coal tar or tree sap on the paint surface
• If you see dead insects, insect droppings or bird droppings on the paint
• After driving in an area contaminated with soot, oily smoke, mine dust,
iron powder or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzine and gasoline are spilled on the paint surface
● If the paint is chipped or scratched, have it repaired immediately.

Installing tire pressure warning valves and transmitters
When replacing tires or wheels, ti re pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warn ing valve and transmitter ID codes
must be registered in the tire pr essure warning computer and tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your Toyota
dealer.
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When rotating the tires on vehicles differing with front and rear
tire inflation pressures.
● When changing the tire inflation pressure by changing traveling
speed or load weight, etc.
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the pressure benchmark.
■ The tire pressure warning system
Your Toyota is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low
tire inflation pressure before serious problems arise. 

Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. 
When replacing a tire pressure warning valve and transmitter, it is
necessary to register the ID code of tire pressure warning valve and
transmitter. Have the ID code registered by your Toyota dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure warning system will not work properly. After
about 20 minutes, the tire pressure warning light comes on after blinking
for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.

■Maximum load of tire
Check that the maximum load of the replaced tire is greater than 1/2 of
the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater. 
As for the maximum load of the tire, see the load limit at maximum cold
tire inflation pressure mentioned on the sidewall of the tire, and as for the
Gross Axle Weight Ratings (GAWR) , see the Certification Label. 
(
P. 331, 417)
■Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tire s, summer tires are inadequate for
driving on snow-covered or icy ro ads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3Snow tires For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( P. 170)
■Initializing the tire pressure warning system
Initialize the tires with the tire inflati on pressure adjusted to the specified
level.
