QWhere to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service operations 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 authoriz ed repairer, or any reliable repairer will
perform all of the scheduled maintenance on your vehicle reliably and eco-
nomically due to their experience with Toyota vehicles.
Q 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:
O Engine missing, stumbling or pinging
O Appreciable loss of power
O Strange engine noises
O A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
O Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)
O Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
O Vehicle pulls to one side when driven straight on a level road
O Strange noises related to suspension movement
O Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal,
pedal almost touches the floor, vehicle pulls to one side when braking
O Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as pos-
sible. Your vehicle may need adjustment or repair.

Maintenance and care
Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread.
Check the spare tire condition and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” mark, etc.,
molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.

Rotate the tires in the order shown.
To equalize tire wear and help extend tire life, Toyota recommends that tire
rotation is carried out approximately every 10000 km (6000 miles).
Q When to replace your vehicle’s tires
Tires should be replaced if:
O The treadwear indicators are showing on a tire.
O You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating internal damage
O 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.
Q 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.
Q 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
WARNING
QWhen 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.
O Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
O Do not use tire sizes other than those recommended by Toyota.
O Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
O Do not mix summer, all season and snow tires.
O 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.
NOTICE
Q Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
Q If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Tire inflation pressure
QEffects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
O Reduced fuel economy
O Reduced driving comfort and poor handling
O Reduced tire life due to wear
O Reduced safety
O Damage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
Q Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
O 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.
O Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
O It is normal for the tire inflation pressure to be higher after driving as heat is
generated in the tire. Do not reduce tire inflation pressure after driving.
O Passengers and luggage weight should be placed so that the vehicle is bal-
anced.
Make sure to maintain proper tire inflation pressure. Tire infla-
tion pressure should be checked at least once per month. How-
ever, Toyota recommends that tire inflation pressure be checked
once every two weeks. ( P. 639)

Maintenance and care
WARNING
QProper 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:
O Excessive wear
O Uneven wear
O Poor handling
O Possibility of blowouts resulting from overheated tires
O Air leaking from between tire and wheel
O Wheel deformation and/or tire damage
O Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
Q 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.

Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset*.
Replacement wheels are available at any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
O Wheels of different sizes or types
O Used wheels
O Bent wheels that have been straightened
O Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
O When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1600 km (1000 miles).
O Be careful not to damage the aluminum wheels when using tire
chains.
O Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.
