■ Aluminum wheels (if equipped)
● Remove any dirt immediately by using a neutral detergent.
● Wash detergent off with water immediately after use.
● To protect the paint from damage, make sure to observe the following pre-
cautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driv-
ing or parking in hot weather
■ Bumpers
Do not scrub with abrasive cleaners.
WARNING
■ When cleaning the windshield
• When the upper part of the windshield where the raindrop sensor is
located is touched by hand
• When a wet rag or similar is held close to the raindrop sensor
• If something bumps against the windshield
• If you directly touch the raindrop sensor body or if something bumps
into the raindrop sensor
● Installation area of front sensor on windshield:P. 289
■ When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components, etc., to catch fire.
■ Precautions regarding the exhaust pipes
Exhaust gases cause the exhaust pipes to become quite hot.
When washing the vehicle, be careful not to touch the pipes until they have
cooled sufficiently, as touching hot exhaust pipes can cause burns.
● Vehicles with a rain-sensing windshield
wiper: Set the wiper switch to off.
If the wiper switch is in “AUTO”, the
wiper may operate unexpectedly in the
following situations, and may result in
hands being caught or other serious
injuries and cause damage to the wiper
blades.

■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 authorized 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
(vehicles with a manual transmission), pedal almost touches the floor, vehi-
cle 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
Vehicles without a smart entry & start system
Be sure the engine switch is in the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 503)
Vehicles with a smart entry & start system
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. 503)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.,
from getting in your eyes.

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.
