Maintenance and Care
After replacing the engine oil, have a repair shop such as your Toyota
dealer perform the initialization (engine oil data resetting) of the
recorded value. If the value recorded by the computer is not initialized,
the wrench indicator light may not turn off or it may turn on earlier than
normal.
● This procedure is intended for vehicles with the engine oil flexible mainte-
nance setting selected.
● The initialization (engine oil data resetting) of the recorded value can be per-
formed using the following procedure:
Switch the ignition OFF.
Vehicle Engine Control Unit Reset Procedure
Switch the ignition ON with the selec-
tor pressed, and press and hold the
selector for about 5 seconds until the
master warning light flashes.
After the master warning light
flashes for several seconds, the ini-
tialization is completed.

Body Lubrication
All moving points of the body, such as door and hood hinges
and locks, should be lubricated each time the engine oil is
changed. Use a nonfreezing l ubricant on locks during cold

Make sure the hood’s secondary latch keeps the hood from
opening when the primary latch is released.

■Washing
●Toyota is not responsible for scratches caused by automatic car washes or
improper washing.
● Scratches are more noticeable on vehicles with darker paint finishes.
■ Waxing
A spot remover to remove oil, tar, and similar materials will usually also take
off the wax. Rewax these areas even if the rest of the vehicle does not need
it.
WARNING
■Dry off brakes that have become wet by driving slowly, releasing the
accelerator pedal and lightly applyi ng the brakes several times until
the brake performance returns to normal
Driving with wet brakes is dangerous. Increased stopping distance or the
vehicle pulling to one side when braking could result in a serious accident.
Light braking will indicate whether the brakes have been affected.
NOTICE
● Do not spray water in the engine compartment. Otherwise, it could result in
engine-starting problems or damage to electrical parts.
● When washing and waxing the vehicle, be careful not to apply excessive
force to any single area of the vehicle roof. Otherwise, you could dent the
vehicle.
● Do not use steel wool, abrasive cleaners, or strong detergents containing
highly alkaline or caustic agents on chrome-plated or anodized aluminum
parts. This may damage the protective coating; also, cleaners and deter-
gents may discolor or deteriorate the paint.

Maintenance and Care
• When cleaning the plastic lenses of the lights, do not use gasoline,
kerosene, rectified spirit , paint, thinner, highly acidic detergents, or
strongly alkaline detergents. Other wise, these chemical agents can
discolor or damage the surfaces resulting in a significant loss in
functionality. If plastic parts beco me inadvertently exposed to any of
these chemical age nts, flush with water immediately.
• If plastic parts such as the bu mpers become inadvertently exposed
to chemical agents or fluids such as gasoline, oil, engine coolant, or
battery fluid, it could cause discoloration, stai ning, or paint peeling.
Wipe off any such chemical agents or fluids using a soft cloth imme-
diately.
• High water temperature and high water pressure car washers are available depending on the type of high pressure car washer
device. If the car washer nozzle is put too close to the vehicle or
aimed at one area for an extended period of time, it could deform
plastic parts or damage the paint.
• Do not use wax containing compounds (polish). Otherwise, it could
result in paint damage.
• In addition, do not use an electrical or air tool to apply wax. Other-
wise, the frictional heat generat ed could result in deformation of
plastic parts or paint damage.
NOTICE
● Do not use any detergent other than mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor or stain the aluminum wheels.
● Do not use a wire brush or any abrasive cleaner, polishing compound, or
solvent on aluminum wheels. They may damage the coating.
● Always use a sponge or soft cloth to clean the wheels.
Rinse the wheels thoroughly with lukewarm or cold water. Also, be sure to
clean the wheels after driving on dusty or salted roads to help prevent cor-
rosion.
● Avoid washing your vehicle in an automatic car wash that uses high-speed
or hard brushes.

YARIS iA_OM_OM99Q46z_(U)
Electronic Brake Force Distribution System Warning
If the electronic brake force distribution control unit deter-
mines that some components are operating incorrectly,
the control unit may illuminate the brake system warning
light and the ABS warning light simultaneously. The prob-
lem is likely to be the electronic brake force distribution
system.
Charging System Warning Light
If the warning light illuminates while driving, it indicates a
malfunction of the alternator or of the charging system.
Drive to the side of the road and park off the right-of-way.
Consult your Toyota dealer.
Engine Oil Warning LightThis warning light indicates low engine oil pressure.
If the light illuminates or the warning indication is dis-
played while driving:
Drive to the side of the road and park off the right-of-
way on level ground.
Turn off the engine and wait 5 minutes for the oil to
drain back into the oil pan.
Inspect the engine oil level P. 424. If it’s low, add the
appropriate amount of engine oil while being careful
not to overfill.
Start the engine and check the warning light.
If the light remains illuminated even though the oil level is
normal or after adding oil, stop the engine immediately
and have your vehicle towed to your Toyota dealer.

■Power Steering Malfunction Indicator Light
●If the indicator light illuminates/flashes, the power steering will not operate
normally. If this happens, the steering wheel can still be operated, however,
the operation may feel heavy compared to normal, or the steering wheel
could vibrate when turning.
● Repeatedly jerking the steering wheel left and right while the vehicle is
stopped or moving extremely slowly will cause the power steering system to
go into protective mode which will make the steering feel heavy, but this
does not indicate a problem. If this occurs, park the vehicle safely and wait
several minutes for the system to return to normal.
WARNING
■Do not drive with the brake system warning light illuminated. Contact
your Toyota dealer to have the brakes inspected as soon as possible
Driving with the brake system warning light illuminated is dangerous. It indi-
cates that your brakes may not work at all or that they could completely fail
at any time. If this light remains illuminated, after checking that the parking
brake is fully released, have the brakes inspected immediately.
In addition, the effectiveness of the braking may diminish so you may need
to depress the brake pedal more strongly than normal to stop the vehicle.
■ Do not drive with both the ABS warning light and brake warning light
illuminated. Have the vehicle towed to your Toyota dealer to have the
brakes inspected as soon as possible
Driving when the brake system warning light and ABS warning light are illu-
minated simultaneously is dangerous.
When both lights are illuminated, the rear wheels could lock more quickly in
an emergency stop than under normal circumstances.
NOTICE
■ Charging System Warning Light
Do not continue driving when the charging system warning light is illumi-
nated because the engine could stop unexpectedly.
■ Engine Oil Warning Light
● Do not run the engine if the oil pressure is low. Otherwise, it could result in
extensive engine damage.
● Do not run the engine if the oil level is low. Otherwise, it could result in
extensive engine damage.
■ High Engine Coolant Temperature Warning Light
Do not drive the vehicle with the high engine coolant temperature warning
light illuminated. Otherwise, it could result in damage to the engine.
