3-10. Active Safety System
WARNING
■Do not rely on the Smart City B rake Support System (SCBS) as a sub-
stitute for safer driving
The Smart City Brake Support (SCBS) system cannot compensate for
unsafe and reckless driving, excessive speed, tailgating (follo wing another
vehicle too closely), and driving on slippery roads such as wet , snowy, and
icy roads (reduced tire friction and road contact because of wa ter on the
road surface). You can still have an accident.
■ Do not rely completely on the Smart City Brake Support (SCBS) s ystem
● The Smart City Brake Support (SCBS) system is only designed to reduce
damage in the event of a collision. Over reliance on the system leading to
the accelerator pedal or brake pedal being mistakenly operated could
result in an accident.
● The Smart City Brake Support (SCBS) is a system which operates in
response to a vehicle ahead. The system may not be able to detect or
react to two-wheeled vehicles or pedestrians.
● The laser sensor for the Smart City Brake Support (SCBS) system is
installed near the rearview mirror. To assure the correct opera tion of the
Smart City Brake Support (SCBS), heed the following cautions.
• Do not apply stickers to the surface of the windshield near the laser sensor (including transparent stickers). Otherwise, the laser s ensor
may not be able to detect vehicles ahead which could result in an acci-
dent.
• Do not apply coating agent to the windshield. Otherwise, the l aser sen-
sor may not be able to detect vehicles or obstructions in front which
could result in an accident.
• Do not disassemble the laser sensor.
• If cracks or damage caused by flying gravel or debris is visib le near
the laser sensor, stop using the Smart City Brake Support (SCBS )
system immediately and have your vehicle inspected by your Toyo ta
dealer. If the vehicle continues to be driven with cracks or sc ratch
marks left on the windshield near the laser sensor, the system may
operate unnecessarily and cause an unexpected accident.
Refer to Stopping The Smart City Brake Support (SCBS) System
Operation on P. 222.
• When replacing the windshield wi pers or windshield, consult your
Toyota dealer.
● The laser sensor includes a function for detecting a soiled windshield and
informing the driver, however, depending on the conditions, it may not
detect plastic shopping bags, ice or snow on the windshield. In such
cases, the system cannot accurately determine a vehicle ahead a nd may
not be able to operate normally. Always drive carefully and pay attention to
the road ahead.

When Driving
Laser Sensor
Always keep the surface of the
windshield around the laser sen-
sor clean to assure proper opera-
tion of the Smart City Brake
Support (SCBS) system.
: If equipped
The Smart City Brake Support (SCBS) laser sensor is installed at
the top of the windshield near the rearview mirror.
WARNING
■ As there is the possibility of eye damage occurring from the la ser,
always heed the following precautions
● Never remove the sensor.
● A removed sensor will not meet the conditions for a class 1M la ser under
the IEC 60825-1 specification and therefore eye safety cannot b e assured.
● Do not peer into the sensor using optical instruments with a ma gnification
function such as magnifying glasses, and microscopic and object ive
lenses within a distance of 3.94 in. (100 mm) from the sensor.

3-12. Tire Pressure Monitoring System
Tire Pressure Monitoring System
The system monitors the tire pres-
sures indirectly using the data
sent from the ABS wheel speed
sensors.
To allow the system to operate correctly, the system needs to be ini-
tialized with the specified tire pressure (value on the tire pressure
label). Follow the procedure and perform the initialization.
Refer to Tire Pressure Monitorin g System Initialization on P. 233.
The warning light flashes when the system has a malfunction.
Refer to Warning Lights on P. 162.
: If equipped
The Tire Pressure Monitoring S ystem (TPMS) monitors the air
pressure of all four tires. If the air pressure of one or more tires
is too low, the system warns the driver by indicating the tire
pressure monitoring system warning light in the combination
meter and operating a beep sound.

Maintenance and Care
Wiper Blades
Contamination of either the windshield or the blades with for-
eign matter can reduce wiper effectiveness. Common sources
are insects, tree sap, and hot wax treatments used by some
commercial car washes.
If the blades are not wiping properly, clean the window and
blades with a good cleaner or mild detergent; then rinse thor-
oughly with clean water . Repeat if necessary.
WARNING
When the wiper lever is in the AUTO position and the ignition i s switched
ON, the wipers may move automatically in the following cases
● If the windshield above the rain sensor is touched.
● If the windshield above the rain sensor is wiped with a cloth.
● If the windshield is struck with a hand or other object.
● If the rain sensor is struck with a hand or other object from i nside the vehi-
cle.
Be careful not to pinch hands or fingers as it may cause injury , or damage
the wipers. When washing or servicing the vehicle, make sure th e wiper
lever is in the OFF position.
NOTICE
● Hot waxes applied by automatic car washers have been known to a ffect
the wiper’s ability to clean windows.
● To prevent damage to the wiper blades, do not use gasoline, ker osene,
paint thinner, or other solvents on or near them.

4865-4. Appearance Care
YARIS SEDAN_OM_OM99S50z_(U)
■Washing
●Toyota is not responsible for scratches caused by automatic car washes or
improper washing.
● Scratches are more noticeable on vehicles with darker paint fin ishes.
■ 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, releasin g the
accelerator pedal and lightly applying the brakes several times until
the brake performance returns to normal
Driving with wet brakes is dangerous. Increased stopping distan ce or the
vehicle pulling to one side when braking could result in a seri ous accident.
Light braking will indicate whether the brakes have been affect ed.
NOTICE
●When the wiper lever is in the position and the ignition is sw itched
ON, the wipers may move automatically in the following cases:
• If the windshield above the rain sensor is touched or wiped wi th a cloth.
• If the windshield is struck with a hand or other object from e ither outside
or inside the vehicle.
Keep hands and scrapers clear of the windshield when the wiper lever is
in the position and the ignition is switched ON as fingers cou ld be
pinched or the wipers and wiper blades damaged when the wipers acti-
vate automatically.
If you are going to clean the windshield, be sure the wipers ar e turned off
completely (when it is most likely that the engine is left runn ing) this is par-
ticularly important when clearing ice and snow.
● Do not spray water in the engine compartment. Otherwise, it cou ld result in
engine-starting problems or damage to electrical parts.
● When washing and waxing the vehicle, be careful not to apply ex cessive
force to any single area of the vehicle roof or the antenna. Ot herwise, you
could dent the vehicle or damage the antenna.
● 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 a nd deter-
gents may discolor or deteriorate the paint.
