Tire Pressure MonitoringSystem (TPMS)
The TPMS monitors the air pressure of
each tire and informs the driver of a
decrease in the tire air pressure when it
becomes lower than the specified air
pressure.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.
1. Tire pressure sensor
Warning and Cautions forUsing the Tire Pressure Monitoring System
(TPMS)
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light
is
turned on or flashing.
Driving the vehicle at high speeds
while the TPMS warning light is turned
on or flashing is dangerous because
the brake performance and the
steering wheel operability will be
reduced. If the vehicle is driven at high
speeds or the brakes are suddenly
applied, it could lead to an accident.
Gradually apply the brake and reduce
the vehicle speed.
Do not ignore the TPMS warning light
when it is turned on or flashing.
Continuing to driv e the vehicle while
ignoring the illumi nation/flashing of
the TPMS warning light is dangerous
because a tire may burst which could
lead to an accident. Take appropriate
measures as soon as possible.

Smart Brake Support(SBS)
*
SBS is a system designed to avoid
collisions and reduce damage in the
event of a collision by controlling the
brakes. Sensors and camera equipped
on the vehicle detect objects, and
operate brake control if there is a
possibility of your vehicle colliding with
the object.
One part of the SBS functions when
you are driving forward and the other
part functions when you are driving in
reverse.
Forward drive detection
Forward drive detection has the
following 4 functions.
Forward detection function
*
The forward detection function is
designed to assist the driver in avoiding
collisions with objects (vehicles ahead,
pedestrians, bicycles, and motorcycles)
at the front and to reduce damage in
the event of a collision.
If there is a possibility of your vehicle
colliding with a target object at the
front, you are notified of possible
danger by a screen display and a
warning sound. Furthermore, if the
possibility of a collision increases,
brake control is performed to avoid
collision and reduce damage in the
event of a collision.
In addition, when the driver depresses
the brake pedal, the brakes are applied
firmly and quickly to assist.
Tu r n -A c ro s s Tra ffi c*
The Turn-Across Traffic is designed to
assist the driver in avoiding a collision
with a vehicle approaching in the
opposite direction when making a left
turn at an intersection and to reduce
damage in the event of a collision.
If there is a possibility of your vehicle
colliding with a vehicle approaching in
the opposite direction when you make
a left turn at an intersection, you are
notified of possible danger by a screen
display and a warning sound.
Furthermore, if the possibility of a
collision increases, brake control is
performed to avoid collision and
reduce damage in the event of a
collision.
