Pre-Collision Throttle Management
Continued from previous page
Do not intentionally depress the accelerator pedal excessively when there
are obstacles nearby. If the driver relies only on Pre-Collision Throttle
Management to control acceleration, collisions may occur.
If your vehicle is trapped on a railroad crossing and you are trying to
escape by driving through the crossing gate, the stereo cameras may rec-
ognize the crossing gate as an obstacle and Pre-Collision Throttle
Management system may activate. In this case, remain calm and either
continue to depress the accelerator pedal or turn off the Pre-Collision
Throttle Management system.
Pre-Collision Throttle Management may not activate depending on the fol-
lowing conditions:
- The distance between your vehicle and the obstacle, speed difference,
and lateral displacement (amount of offset)
- Recognition status of the stereo cameras
In particular, the function may not activate in the following cases:
•• Bad weather (for example heavy rain, a blizzard or thick fog)
•• When visibility is poor due to sand or smoke in the air
•• When light is poor in the evening, early morning, or at night
•• In a dark area (indoor parking area, etc.)
•• With low obstacles (low wall, crash barrier, low vehicle, etc.)
•• When the size and height of an obstacle is smaller than the limitations
of the stereo cameras’' recognition capability
•• With small animals or children.
•• With pedestrians who are sitting or lying down
•• When the rear aspect of the vehicle or object in front is small (for exam-
ple a trailer) or when your vehicle is too close to it (the system may rec-
ognize another part of the vehicle as its rear end, and may not operate
properly)
•• When an obstacle (another vehicle, motorcycle, bicycle, pedestrian,
animal or child, etc.) cuts in from the side or jumps out suddenly
•• When starting, if you change lanes and your vehicle is immediately
behind the obstacle
•• When affected by strong light from the front (for example sunlight at
sunrise or sunset headlight high beams, etc.)
•• When there is snow, frost, dirt or dust on the windshield, or it is clouded
•• When fluid has not been fully wiped off the windshield during or after
use of the window washer
•• When obstacles cannot be correctly recognized due to water droplets
from rain or the washer, or the wiper blades obstructing the stereo cam-
eras’' field of view
•• When the stereo cameras’' field of view is obstructed (for example by a
canoe on the roof of the vehicle)
•• When there is an obstacle outside the area illuminated by the head-
lights
•• On sharp curves, steep uphill grades or steep downhill grades
