Distance & Speed Alert(DSA)
*
▼Distance & Speed Alert (DSA)
The DSA is a system which provides
advice for maintaining the appropriate
distance between vehicles and
notifies
the driver of the recommended, safe
distance to maintain with a vehicle
ahead. The system measures the
distance between your vehicle and a
vehicle ahead while the vehicle speed
is about 30 km/h (19 mph) or faster. If
the distance between your vehicle and
a vehicle ahead is close, the system
alerts the driver of a possible collision
using an indication on the display.
WARNING
Do not rely completely on the DSA :
The ability of the system to detect a
vehicle ahead is limited depending on
the type of vehicle ahead, weather
conditions, or tra ffic conditions. In
addition, the system is not for
maintaining the distance between your
vehicle and a vehicle ahead. If you
neglect to operate the accelerator and
brake pedals correctly, it could lead to
an accident. Always check the safety of
the surrounding area and depress the
brake pedal or accelerator pedal while
keeping a safe distance from vehicles
ahead or on-coming vehicles.

Tra ffic Jam Assist (TJA)*
▼ Tra
ffic Jam Assist (TJA)
The TJA is a system which consists of a
headway control function and a
steering assist function for reducing
driver fatigue during tra
ffic jams when
driving on expressways or highways.
This system performs headway control
to maintain a constant distance
between your vehicle and a vehicle
ahead at a preset vehicle speed
without you having to use the
accelerator or brake pedal. Even
further, with the steering assist
function, when vehicle lane lines are
detected, the function assists the driver
in keeping the vehicle within the lane
lines. If lane lines are not detected, the
function provides the driver driving
assistance in keeping the vehicle along
the motion path with the vehicle
ahead.
WARNING
Do not rely completely on TJA:
 The TJA is not an automated driving
system. In addition, the functions
have limitations. Do not rely
completely on the system and always
stay on course using the steering
wheel.
 Set a vehicle speed within the speed
limit according to the road
conditions and the weather
conditions.

Lane-keep Assist System
(LAS)
*
▼Lane-keep Assist System (LAS)
The LAS provides steering assistance to
help the driver stay within the vehicle
lane if the vehicle might be deviating.
The forward sensing camera (FSC)
detects the white lines (yellow lines) of
the vehicle lane in which the vehicle is
traveling and if the system determines
that the vehicle may deviate from its
lane, it operates the electric power
steering to assist the driver’s steering
operation. The system also alerts the
driver by displaying an alert on the
multi-information display. Use the
system when you drive the vehicle on
roads with white (yellow) lines such as
expressways and highways.
1. Forward sensing camera (FSC)
WARNING
Do not rely completely on the LAS
:
 The LAS is not an automated driving
system. In addition, the system is not
designed to compensate for a
driver’s lack of caution, and
over-reliance on the system could
lead to an accident.

You do not need to speak slowly. Speak at a normal speed.When calling a person in the device's phone book, the recognition rate increases
the longer the name is. Errors may oc cur with names that are short such as
“Mama”, “Home”, or “wife”.
Speak clearly, without pausing between words or numbers.Voice commands other than those specified, cannot be recognized. Speak in the
wording speci fied by the voice commands.
It is not necessary to face the microphone or approach it. Speak the voice
commands while maintaining a safe driving position.
Close the windows and the moonroof* to reduce loud noises from outside the
