Traffic 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 traffic 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.
The TJA may not be able to detect a
vehicle ahead depending on the type of
vehicle ahead and its conditions, the
weather conditions, and the road
conditions. Additionally, the system
might be unable to decelerate suciently
if a vehicle ahead applies the brakes
suddenly, another vehicle cuts into the
driving lane, or the dierence in vehicle
speed between your vehicle and the
vehicle ahead is larger, which could
result in an accident. Check the
surrounding conditions and always drive
carefully while keeping a safe distance
from vehicles ahead and on-coming
vehicles.
For the purposes of safety, switch the TJA
o when it is not being used.
Leaving the TJA turned on when it is not in
use is dangerous as it could operate
unexpectedly, resulting in an accident.
Do not use the TJA under the following
conditions. Otherwise, it may result in an
accident.
General roads other than expressways or
highways (Driving under these
conditions using the TJA is not possible.)
Roads with sharp curves and where
vehicle trac is heavy with insucient
space between vehicles, or roads where
frequent and repetitive acceleration and
deceleration occur (Driving under these
conditions using the TJA is not possible).
