STARTING AND OPERATING
120
Suspension Conditions
The following operations will suspend the TJA
system:
Pressing the brake pedal
Opening the driver’s door
Disabling ACC
If the vehicle speed exceeds 37 mph
(60 km/h)
Releasing the driver’s seat belt
Placing the gear selector in PARK,
REVERSE, or NEUTRAL
If the Forward Collision Warning system or
“Active Braking” intervenes
Automatic Deactivation
System operation will be temporarily disabled
under the following conditions:
When traveling around narrow bends
If the lane boundaries are not detected
One of the two lines is interrupted
The sun is low and reflects on the radar
camera
If the turn signals are activated
If the driver intentionally changes lanes
without using the turn signal
If manual steering begins
If the driver’s hands are removed from the
steering wheel
When there is no surrounding traffic and
there are no horizontal lane boundaries
If the system is not functioning properly
If lateral acceleration is high
NOTE:
When TJA is turned off, the symbol in the
instrument cluster display will turn red, and
then grey.
A sensor in the steering wheel detects
whether the driver’s hands are placed on
the steering wheel.
When the automatic suspension conditions
are over, the TJA system will be automatically
reactivated.
Operation
The TJA system can only operate when the
driver’s hands are on the steering wheel.
If the system detects that the driver’s hands
have been removed from the steering wheel, a
message will appear in the instrument cluster
display to alert the driver to place their hands
back on the wheel.
NOTE:
If the vehicle begins to cross the lane
boundary, the steering wheel will vibrate
and a dedicated screen will appear in the
instrument cluster display.
The TJA system may take up to five seconds
to become active once all conditions are met.
The following conditions must be met in order
to activate the system:
The TJA system must be enabled
The Adaptive Cruise Control (ACC) system
must be turned on
The right and left lane boundaries must be
recognized by the system
The vehicle must be traveling at a speed
between 0 and 37 mph (0 and 60 km/h)
The camera, radar, and radio system must
be functioning properly
The road lane width must be between 8.5 ft
and 13.7 ft (2.6 m and 4.2 m)
The turn signals must be turned off
The TJA system must be functioning properly
If the ACC speed is set to 37 mph (60 km/h)
or less, traveling downhill may increase the
vehicle speed. The system will remain inac-
tive until the speed returns to 37 mph
(60 km/h) or less.
