4627-1. Maintenance and care
NOTICE
• If the vehicle becomes heavily
soiled with dust or mud
• If liquids such as benzene and gas-
oline are spilled on the paint sur-
face
●If the paint is chipped or scratched,
have it repaired immediately.
●To prevent the wheels from corrod-
ing, remove any dirt and store in a
place with low humidity when stor- ing 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 surfaces of
the lights.
Wax may cause damage to the lenses.
■To prevent damage to the wind-shield 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 an automatic car
wash (vehicles with rain-sensing
windshield wipers)
Set the wiper switch to the off posi-
tion. If the wiper switch is in “AUTO”,
the wipers may operate and the wiper blades may be damaged.
■When using a high pressure car wash
●Vehicles with rear view monitor sys-
tem: 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 manufac- tured cover), connectors or the fol-
lowing parts. The parts may be
damaged if they come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
•Brake parts
●Keep the cleaning nozzle at least
30 cm (11.9 in.) away from the vehi-
cles body. Otherwise resin section, such as moldings and bumpers,
may 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 c onditioning system
intake located near the lower part of the windshield, the air conditioning
system may not operate correctly.

mends that maintenance service opera-
tions as well as other inspections and repairs be carried out by authorized
Toyota retailers or Toyota authorized
repairers, or any reliable repairers. For repairs and services covered by your
warranty, please visit an authorized
Toyota retailer or repairer, who will use genuine Toyota parts in repairing any
difficulties you may encounter. There
can also be advantages in utilizing authorized Toyota retailers or repairers
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 retailer or Toyota authorized
repairer, or any reliable repairer will per- form all of the scheduled maintenance
on your vehicle reliably and economi-
cally due to their experience with Toyota vehicles.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance
schedule.

schedule, read the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.
What about do-it-yourself mainte-
nance?
Many of the 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 experi-
enced do-it-yourself mechanic, we rec-
ommend that repairs and maintenance
be conducted by any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer. Any authorized
Toyota retailer or repairer will keep a
record of maintenance, which could be
useful should you ever require War-
ranty Service. Should you choose to
select a qualified and equipped profes-
sional other than an authorized Toyota
repairer to service or maintain your
vehicle, we recommend that you

cators are showing on a tire.
■When to replace your vehicle’s
tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating inter-
nal damage
●A tire goes flat repeatedly or cannot
be properly repaired due to the size or location of a cut or other damage
If you are not sure, consult with any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if
it has seldom or never been used or
damage is not obvious.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow
tires is lost.

Maintenance and care
Vehicles with a full-size spare tire
Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
If the tire pressure drops below a
predetermined level, the driver is
warned by a warning light.
( P.515)
■Routine tire inflation pressure
checks
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily vehicle checks.
■Situations in which the tire pres-
sure warning system may not oper-
ate properly
●In the following cases, the tire pres-
sure warning system may not operate
properly. • If non-genuine Toyota wheels are
used.
• A tire has been replaced with a tire that is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio
wave signals is installed. • If there is a lot of snow or ice on the
vehicle, particularly around the wheels
or wheel housings. • If the tire inflation pressure is
extremely higher than the specified
level. • If tires not equipped with tire pressure
warning valves and transmitters are
used. • If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant,
gas station, radio station, large dis- play, airport or other facility that gen-
erates strong radio waves or electrical
noise. • When carrying a portable radio, cellu-
lar phone, cordless phone or other
wireless communication device.
●When the vehicle is parked, the time
taken for the warning to start or go off could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure warning system will change in accordance with
driving conditions. For this reason, the
system may give a warning even if the tire pressure does not reach a low
enough level, or if the pressure is higher

■When initialization of the tire pres-
sure warning system has failed
Initialization can be completed in a few
minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to
record tire inflation pressure settings are unsuccessful, have the vehicle
inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
●When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●After driving for a certain period of
time since the initialization has been
completed, the wa rning light comes on after blinking for 1 minute.
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 regis-
ter the ID code. Have the ID code
registered by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
Your vehicle is equipped with tire
pressure warning system with the
function to have ID codes regis-
tered for a second wheel set, for
example a winter set, by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
After registration of a second wheel
set, either of these two wheel sets
can be selected for usage with the
tire pressure warning system.
■Operating conditions for the
function
 This function will perform the
change of wheel set only if a sec-
ond wheel set has been regis-
tered. If no second wheel set has
been registered, no change will
be made when selecting this
function in the menu.
 Only a change between both
registered wheel set is possible,
mixing between these wheel sets
is not supported.
■How to change between wheel
sets
1 Have the vehicle fitted with the
preferred wheel set.
2 Press or of the meter
control switch to select .

■When initializing the tire pres-
sure warning system
Do not initialize the tire pressure warning system withou t first adjusting
the tire inflation pressure to the speci-
fied level. Otherwise, the tire pressure warning light may not come on even if
the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.

■Instructions for checking tire infla-
tion pressure
When checking tire inflation pressure,
observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at
least 3 hours or has not been driven for more than 1.5 km or 1 mile, you
will get an accurate cold tire inflation
pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appearance.
●It is normal for the tire inflation pres-sure to be higher after driving as heat
is generated in the tire. Do not reduce
tire inflation pressure after driving.
●Passengers and luggage weight
should be placed so that the vehicle is balanced.
WA R N I N G
■Proper inflation is critical to save
tire performance
Keep your tires properly inflated. If the tires are not properly inflated,
the following conditions may occur
which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire dam-age
●Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges on
the road, etc.)
NOTICE
■When inspecting and adjusting
tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or
moisture may get into the valve and cause an air leak, resulting in
decreased tire inflation pressure.
