Active Safety System∗
◆Pre-Crash Safety Technology
Pre-crash safety technology is designed to assist the driver in
averting collisions or re duce their severity in situations where they
cannot be avoided.
● Collision damage reduction in low vehicle speed range
Forward driving:
Smart City Brake Support (SCBS) ( →P. 205)
◆Sensor
● Laser sensor
The laser sensor emits a near-infrared laser beam and receives
the beam reflected off the reflec tive surface of a vehicle or
obstruction in front, and the detected beam is then used for mea-
surement. The laser sensor is used for the Smart City Brake
Support (SCBS) system.
The laser sensor is installed at the top of the windshield near the
rearview mirror.
Refer to Laser Sensor on P. 211.

When Driving
Smart City Brake Support (SCBS)∗
∗: If equipped
The Smart City Brake Support (SCBS) system is designed to
reduce damage in the event of a collision by operating the brake
control (SCBS brake) when the system’s laser sensor detects a
vehicle ahead and determines that a collision with a vehicle
ahead is unavoidable. It may also be possible to avoid a colli-
sion if the relative speed between your vehicle and a vehicle
ahead is less than about 12 mph (20 km/h).
In addition, when the driver depresses the brake pedal while the
system is in the operation range at about 2 to 18 mph (4 to
30 km/h), the brakes are applied firmly and quickly to assist.

3-10. Active Safety System
●The Smart City Brake Support (SCBS) system will not operate if the driver is
deliberately performing driving operations (accelerator pedal and steering
wheel).
● The Smart City Brake Support (SCBS) system will operate under the follow-
ing conditions.
• The engine is running.
• The Smart City Brake Support (SCB S) warning light (amber) does not
illuminate.
• The vehicle speed is between about 2 to 18 mph (4 to 30 km/h).
• The Smart City Brake Support (SCBS) system is not turned off.
• The DSC is not malfunctioning.
● The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a
near-infrared laser beam and receiving the beam reflected off the reflector
of the vehicle ahead, and then using it for the measurement. Consequently,
the Smart City Brake Support (SCBS) may not operate under the following
conditions:
• Reflection of the laser is poor due to the shape of the vehicle ahead.
• The vehicle ahead is significantly dirty.
• Under bad weather condition, such as rain, fog and snow.
• The window washer is being used or the windshield wipers are not used
when it’s raining.
• The windshield is dirty.
• The steering wheel is turned completely left or right, or the vehicle is
accelerated rapidly and comes close to the vehicle ahead.
• Trucks with low loading platforms and vehicles with an extremely low or high profile.
• Vehicles with certain shapes such as a vehicle carrier.
● Under the following conditions, the Smart City Brake Support (SCBS) sys-
tem may not operate normally.
• Heavy luggage is loaded in the luggage compartment or on the rear seat.
• If there is the possibility of partial contact with a vehicle ahead.
• When driving on continuously curving roads, and entering and exiting
exits.
• Elongated luggage or cargo is loaded onto installed roof rails and covers the laser sensor.
• Exhaust gas from the vehicle in front, sand, snow, and water vapor rising
from manholes and grating, and water splashed into the air.
• When towing a malfunctioning vehicle.
• When driving with tires having significantly different wear.

When Driving
●In the following cases, the laser sensor may inadvertently determine that
there is a vehicle ahead and the Smar t City Brake Support (SCBS) system
may operate.
• Objects on the road at the entrance to a curve.
• Vehicles passing in the opposite lane while making a curve.
• Metal objects, bumps, or protruding objects on the road.
• When passing through a toll gate equipped with a bar.
• When passing under a vinyl curtain or flag.
• Plastic objects such as pylons.
• Two-wheeled vehicles, pedestrians, animals or standing trees.
● Manual transaxle:
If the vehicle is stopped by the SCBS operation and the clutch pedal is not
depressed, the engine stops.
● The Smart City Brake Support (SCBS) warning light (amber) turns on when
the system has a malfunction.
Refer to Warning Lights on P. 157.

WARNING
■Do not rely on the Smart City Br ake Support System (SCBS) as a sub-
stitute for safer driving
The Smart City Brake Support (SCB S) system cannot compensate for
unsafe and reckless driving, excessive speed, tailgating (following another
vehicle too closely), and driving on slippery roads such as wet, snowy, and
icy roads (reduced tire friction and road contact because of water on the
road surface). You can still have an accident.
■ Do not rely completely on the Sm art City Brake Support (SCBS) system
● 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 (SCB S) 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 operation 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 sensor
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 laser 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 visible near
the laser sensor, stop using the Smart City Brake Support (SCBS)
system immediately and have your vehicle inspected by your Toyota
dealer. If the vehicle continues to be driven with cracks or scratch
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. 210.
• When replacing the windshield wipers 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 and 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 laser,
always heed the following precautions
● Never remove the sensor.
● A removed sensor will not meet the conditions for a class 1M laser under
the IEC 60825-1 specification and therefore eye safety cannot be assured.
● Do not peer into the sensor using optical instruments with a magnification
function such as magnifying glasses, and microscopic and objective
lenses within a distance of 3.94 in. (100 mm) from the sensor.
