Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year
to maintain the quality of the vehicle’s interior.
Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a
sponge or brush to apply the foam. Rub in overlapping circles. Do not apply
water. Excellent results are obtained when keeping the carpet as dry as pos-
sible.
Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
CAUTION
Water in the vehicle
Do not splash or spill liquid in the vehicle. Doing so may cause the electri-
cal components etc. to malfunction or catch fire.
Do not get any of the SRS components or wiring in the vehicle interior wet.
(P. 125)
Electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or severe injury.
Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off
the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.

NOTICE
Cleaning detergents
Do not use organic substances such as benzene or gasoline, acidic or
alkaline solutions, dye, bleach or other detergent. Doing so may discolor
the vehicle interior or cause streaks or damage to painted surfaces.
Do not use polish wax or polish cleaner. The instrument panel’s or other
interior part’s painted surface may be damaged.
Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces.
Remove any dust or dirt on leather surfaces immediately.
Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
Do not place items made of vinyl, plastic, or that contain wax on the uphol-
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 under the floor of the vehicle, and
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
with lukewarm water to gently wipe the window clean. Wipe the window in
strokes running parallel to the heater wires.
Be careful not to scratch or damage the heater wires.

Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance is essential. Toyota recommends the following mainte-
nance.
Scheduled maintenance
Scheduled maintenance be performed at specified intervals
according to the maintenance schedule.
For full details of your maintenance schedule, read the “Toyota
Service Booklet” or “Toyota Warranty Booklet”.
Do-it-yourself maintenance
What about do-it-yourself maintenance?
Many 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 experienced do-it-yourself mechanic, we recommend that
repairs and maintenance be conducted by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional. Any authorized Toyota dealer 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 profes-
sional other than an authorized Toyota repairer to service or maintain
your vehicle, we recommend that you request that a record of mainte-
nance be kept.

Does your vehicle need repair?
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 driving straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake 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.
CAUTION
If your vehicle is not properly maintained
It could result in serious damage to the vehicle and possible serious injury or
death.

CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically 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 or rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel or 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, see a doctor.
When working near the electric cooling fan or radiator grille
Vehicles without 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 system is on and/or the
coolant temperature is high. (P. 342)
Vehicles with smart entry & start system:
Be sure the “ENGINE START STOP” switch is in the OFF.
With the “ENGINE START STOP” switch in the IGNITION ON mode, the
electric cooling fan may automatically start to run if the air conditioning
system is on and/or the coolant temperature is high. (P. 342)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

NOTICE
If you remove the air cleaner
Driving with the air cleaner 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.
