4-1. Maintenance and care  
Cleaning and protecting the vehicle exterior  
Perform the following to protect the vehicle and maintain it in prime  
condition.  
Working from top to bottom, liberally apply water to the vehicle  
body, wheel wells and underside of the vehicle to remove any  
dirt and dust.  
Wash the vehicle body using a sponge or soft cloth, such as a  
chamois.  
For hard-to-remove marks, use car wash soap and rinse thor-  
oughly with water.  
Wipe away any water.  
Wax the vehicle when the waterproof coating deteriorates.  
If water does not bead on a clean surface, apply wax when the vehicle  
body is cool.  
Automatic car washes  
Fold the mirrors back before washing the vehicle.  
Brushes used in automatic car washes may scratch the vehicle surface  
and harm your vehicle’s paint.  
High pressure car washes  
Do not allow the nozzles of the car wash to come within close proximity of  
the windows. Before entering an automatic car wash, check that the fuel filler  
door on your vehicle is closed properly.  
Aluminum wheels (if equipped)  
Remove any dirt immediately by using a neutral detergent. Do not use hard  
brushes or abrasive cleaners. Do not use strong or harsh chemical cleaners.  
Use the same mild detergent and wax as used on the point.  
Bumpers and side moldings  
Do not scrub with abrasive cleaners.  
208  
4-1. Maintenance and care  
To prevent deterioration and body corrosion  
Wash the vehicle immediately in the following cases:  
• After driving near the sea coast  
• After driving on salted roads  
• If you see coal tar or tree sap on the paint surface  
• If you see dead insects or insect droppings on the paint  
• After driving in an area contaminated with soot, oily smoke, mine dust,  
iron powder or chemical substances  
• If the vehicle becomes heavily soiled in dust or mud  
• If liquids such as benzene and gasoline are spilled on the paint surface  
If the paint is chipped or scratched, have it repaired immediately.  
CAUTION  
Caution about the exhaust pipe  
Exhaust gasses cause the exhaust pipe to become quite hot.  
When washing the vehicle, be careful not to touch the pipe until it has cooled  
sufficiently, as touching a hot exhaust pipe can cause burns.

NOTICE  
To protect your vehicle’s painted surfaces  
Do not use organic cleaners such as benzene or gasoline.  
Cleaning the exterior lights  
Wash carefully. Do not use organic substances or scrub with a hard brush.  
This may damage the surfaces of the lights.  
Do not apply wax on the surfaces of the lights.  
Wax may cause damage to the lenses.  
To prevent damage to the windshield wiper arms  
When lifting the wiper arms away from the windshield, pull the driver side  
wiper arm upward first, and repeat for the passenger side. When returning  
the wipers to their original position, do so from the passenger side first.

4-1. Maintenance and care  
Cleaning and protecting the vehicle interior  
The following procedures will help protect your vehicle's interior and  
keep it in top condition:  
Protecting the vehicle interior  
Remove dirt and dust using a vacuum cleaner. Wipe dirty sur-  
faces with a cloth dampened with lukewarm water.  
Cleaning the leather areas  
Remove dirt and dust using a vacuum cleaner.  
Wipe any excess dirt and dust with a soft cloth dampened with  
diluted detergent.  
Use a diluted water solution of approximately 5% neutral wool deter-  
gent.  
Wring out any excess water from the cloth and thoroughly  
wipe off all remaining traces of detergent.  
Wipe the surface with a dry, soft cloth to remove any remain-  
ing moisture. Allow the leather to dry in a shaded and venti-  
lated area.  
210  
4-1. Maintenance and care  
Cleaning the inside of the rear window  
Do not use glass cleaner to clean the rear window, as this may cause dam-  
age to the rear window defogger heater wires or antenna. Use a cloth damp-  
ened with lukewarm water to gently wipe the window clean. Wipe the  
window in strokes running parallel to the heater wires or antenna.  
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. The excellent results are obtained when keeping the carpet as dry as  
possible.  
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  
Be careful not to splash or spill liquid on the floor.  
Do not get any of the SRS components or wiring in the vehicle interior wet.  
(P. 67)

4-1. Maintenance and care  
NOTICE  
Cleaning detergents  
Do not use organic substances such as benzene or gasoline, acidic or alka-  
line solutions, dye, bleach or other detergent. Doing so may discolor the  
vehicle interior or cause streaks or damage to painted surfaces.  
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  
Be careful not to scratch or damage the heater wires or antenna.

4-2. Maintenance  
Maintenance requirements  
To ensure safe and economical driving, day-to-day care and regular  
maintenance is essential. It is the owner’s responsibility to perform  
regular checks. Toyota recommends the following maintenance.  
General maintenance  
Should be performed on a daily basis. This can be done by your-  
self or by a Toyota dealer.  
Scheduled maintenance  
Should be performed at specified intervals according to the  
maintenance schedule.  
For details about maintenance items and schedules, refer to the  
“Scheduled Maintenance Guide” or “Owner’s Manual Supplement”.  
Do-it-yourself maintenance  
You can perform some maintenance procedures yourself.  
Please be aware that do-it-yourself maintenance may affect war-  
ranty coverage.

The use of Toyota Repair Manuals is recommended.  
For details about warranty coverage, see the separate “Owner’s  
Warranty Information Booklet”, “Owner’s Manual Supplement”.  
Repair and replacement  
It is recommended that genuine Toyota parts be used for repair to ensure  
performance of each system. If non-Toyota parts are used in replacement or  
if a repair shop other than Toyota dealer performs repairs, confirm the war-  
ranty coverage.  
213  
4-2. Maintenance  
Allow inspection and repairs to be performed by a Toyota dealer  
Toyota technicians are well-trained specialists and are kept up to date  
with the latest service information. They are well informed about the  
operations of all systems on your vehicle.  
Keep a copy of the repair order. It proves that the maintenance that has  
been performed is under warranty coverage. If any problem should arise  
while your vehicle is under warranty, your Toyota dealer will promptly  
take care of it.  
CAUTION

4-2. Maintenance  
Emission inspection and maintenance (I/M) programs  
Some states have vehicle emission inspection programs which  
include OBD (On Board Diagnostics) checks. The OBD system moni-  
tors the operation of the emission control system.  
If the malfunction indicator lamp comes on  
The OBD system determines that a problem exists somewhere  
in the emission control system. Your vehicle may not pass the I/  
M test and may need to be repaired. Contact your Toyota dealer  
to service the vehicle.  
Your vehicle may not pass the I/M test:  
When the battery is disconnected or discharged  
Readiness codes that are set during ordinary driving are  
erased.  
Also, depending on your driving habits, the readiness codes  
may not be completely set.  
When the fuel tank cap is loose  
The malfunction indicator lamp comes on as a temporary mal-  
function and your vehicle may not pass the I/M test.  
When the malfunction indicator lamp goes off after several  
driving trips  
The error code in the OBD system will not be cleared unless the  
vehicle is driven 40 or more times.  
If your vehicle does not pass the I/M test  
Contact your Toyota dealer to prepare the vehicle for re-testing.
