Where to go for maintenance service?
In order to maintain your vehicle in the highest possible condition, Toyota
recommends that all repairs and service operations be carried out by autho-
rized Toyota dealers or repairers or other duly qualified and equipped profes-
sionals. For repairs and services covered by your warranty, please visit an
authorized Toyota dealer or repairer, who will use genuine Toyota parts in
repairing any difficulties you may encounter. There can also be advantages
in utilizing authorized Toyota dealers 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 dealer or repairer, or another duly qualified and equipped pro-
fessional service department will perform all of the scheduled maintenance
on your vehicle - reliably and economically due to their experience with
Toyota vehicles.
Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine missing, stumbling or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon mon-
oxide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
Vehicle pulls to one side when driven straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal,
pedal almost touches the floor, vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.

Maintenance and careInstalling tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warning valve and transmitter ID codes
must be registered in the tire pressure warning computer and tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional. (P. 317)
Vehicles with a spare tire of the same wheel type as the
installed tires
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that tire rotation is car-
ried out approximately every
10000 km (6000 miles).
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.
(P. 375)

318 4-3. Do-it-yourself maintenance
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 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 dealer or repairer, or
another duly qualified and equipped professional.
Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving
for about 10 minutes, the tire pressure warning light comes on after blinking
for 1 minute to indicate a system malfunction.
Tire life
Any tires 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.
Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your rou-
tine of daily vehicle checks.
If the tread on snow tires wears down 4 mm (0.16 in.)
The effectiveness of snow tires is lost.
Low profile tires (vehicles with 17-inch tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.
If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified
level and initialize the tire pressure warning system again.

Maintenance and care
CAUTION
Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a
tire bursts or if sudden air leakage occurs.
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train, as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
Make sure to install 4 tires that are of the specified size, and that all 4 tires
are the same size, same maker, same brand and tread pattern.
Do not use tire sizes other than those recommended by Toyota.
Only use radial tires.
Do not mix summer, all season and snow tires.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the specified 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.

NOTICE
Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact any authorized Toyota dealer or repairer,
or another duly qualified and equipped professional as the tire pressure
warning valves and transmitters may be damaged if not handled correctly.
Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves and the tire
pressure warning valves could be bound.
When replacing tire valve caps, do not use tire valve caps other than those
specified. The cap may become stuck.
To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant is used, contact
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional or other qualified service shop as soon as possible.
Make sure to replace the tire pressure warning valve and transmitter when
replacing the tire. (P. 315)
Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot holes.
These conditions may cause losses in tire air pressure, reducing the cush-
ioning ability of the tires. In addition driving on rough roads may cause dam-
age to the tires themselves, as well as the vehicle’s wheels and body.
Low profile tires and wheels (vehicles with 17-inch tires)
Low profile tires may cause greater damage than usual to the tire wheel
when receiving impact from the road surface. Therefore pay attention to the
following:
Be sure to use proper tire inflation pressure. If tires are under-inflated, they
may be damaged more severely.
Avoid pot holes, uneven pavement, curbs and other road hazards. Failure
to do so can lead to severe tire and wheel damage.
If tire pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent refilling, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Instructions for checking tire 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 and 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.
The appearance of the tire can be misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.
Do not bleed or reduce tire inflation pressure after driving. It is normal for
the tire inflation pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However,
Toyota recommends that tire inflation pressure be checked once
every two weeks. (P. 443)
