■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces:

● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.

stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components such as the audio system above or
under the floor of the vehicle. Water may also cause the body to rust.
■ Cleaning the inside of the rear window
● Do not use glass cleaner to clean the rear window, as this may cause
damage to the rear window defogger heater wires. Use a cloth dampened

Maintenance requirements
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For full details of your maintenance schedule, refer to the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.
What about do-it-yourself maintenance?
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 are
an experienced do-it-yourself mechanic, we recommend 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 Warranty Service. Should you choose to select a qualified
and equipped professional other than an authorized Toyota repairer to ser-
vice or maintain your vehicle, we recommend that you request that a
record of maintenance be kept.
To ensure safe and economical driving, day-to-day care and reg-
ular maintenance are essential. Toyota recommends the follow-
ing maintenance:

Maintenance and care
■Where to go for the maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that all repairs and service operations 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.
■ 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 misfire, 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 monoxide
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
retailer or Toyota authorized repairer, or any reliable repairer as soon as pos-
sible. Your vehicle may need adjustment or repair.

WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become el ectrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the engine compartment
● Keep hands, clothing and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc., right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel on the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
■ When working near the electric cooling fan or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 266)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.,
from getting in your eyes.

Maintenance and care
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
■ If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
