4-5. Using the driving support systems
Pre-collision braking
●
Detectable objects
Vehicles
Bicyclists and pedestrians
*
: Applicable to vehicles designed for regions that detection of pedestrians and/or bicy-
clists is possible (P.285)
The system may not operate in the following situations:
If a 12-volt battery terminal has been disconnected and reconnected and then the vehicle
●
has not been driven for a certain amount of time
If the shift position is in R
●
When the VSC OFF indicator is illuminated (only the pre-collision warning function will
●
be operational)
Object detection function
■
The system detects objects based on their
size, profile, motion, etc. However, an object
may not be detected depending on the sur-
rounding brightness and the motion, pos-
ture, and angle of the detected object,
preventing the system from operating prop-
erly. (P.292)
The illustration shows an image of detecta-
ble objects.
Region A
Region B
LS500h_OM_General_OM50J66E
Vehicle speed
Approx. 10 to 180 km/h (7 to
110 mph)
Approx. 10 to 80 km/h (7 to
*
50 mph)
Region C
Cancelation of the pre-collision braking
■
If either of the following occur while the
pre-collision braking function is operating, it
will be canceled:
The accelerator pedal is depressed
●
strongly.
The steering wheel is turned sharply or
●
abruptly.
Conditions under which the system may
■
operate even if there is no possibility of a
collision
In some situations such as the following,
●
the system may determine that there is a
possibility of a frontal collision and oper-
ate.
• When passing a detectable object, etc.
• When changing lanes while overtaking a
detectable object, etc.
Relative speed between your
vehicle and object
Approx. 10 to 180 km/h (7 to
110 mph)
Approx. 10 to 80 km/h (7 to
50 mph)
