Depending on the vehicle speed, vehicle
condition, road conditions, or conditions of
the area around the vehicle, the lane
change assist function may not operate or it
may be difficult to recognize that it has
operated.
If steering control oper ation is excessive or
insufficient, it can be corrected by the
driver’s operation of the steering wheel.
In situations such as the following, the lane
change assist function may be canceled:
●
When the system no longer detects white
(yellow) lane lines
●
When the turn signal lever is operated

LS500_OM_(U)_1810 operating, if the system detects that a vehi-
cle is quickly approaching in the lane
toward which the turn signal is operated,
the steering assist may slightly steer the
vehicle away from the lane while a buzzer is
sounding, the steering wheel is vibrating,
and a warning display is displayed on the
multi-information display, to help prevent
the vehicle from entering the lane and alert
the driver of the approaching vehicle. ■
Hands off steering wheel alert
In the following situations, a warning mes-
sage urging the driver to hold the steering
wheel and the symbol shown in the illustra-
tion are displayed on the multi-information
display to warn the driver. The warning
stops when the system determines that the
driver holds the steering wheel. Always
keep your hands on the steering wheel
when using this system, regardless of warn-
ings.
Depending on the vehicle condition and
road conditions, the warning may not oper-
ate. Also, if the system determines that the
vehicle is driving around a curve, warnings
will occur earlier than during straight-lane
driving.
●
When the system determines that the
driver is driving without holding the steer-
ing wheel while the sy stem is operating
If the driver continue s to keep their hands
off of the steering wheel, the buzzer
sounds, the driver is warned and the func-
tion is temporarily ca nceled. This warning
also operates in the same way when the
driver continuously operates the steering
wheel only a small amount.
The buzzer also sounds even if the alert
type is set to .

When the system determines that the
driver is driving with out holding the steer-
ing wheel while the st eering wheel assist
of the steering assist function is operating
(vehicles with Lexus Safety System + 2.0)
If the driver continues to keep their hands
off of the steering wheel and the steering
wheel assist is operating, the buzzer
sounds and the driver is warned. Each time
the buzzer sounds, the continuing time of
the buzzer becomes longer.
The buzzer also sounds even if the alert
type is set to .
In situations such as the following, the sys-
tem may not be able to detect when the
driver’s hands are on the steering wheel

240 4-5. Using the driving support systems
LS500_OM_(U)_1810 This mode employs a radar to detect the pr esence of vehicles up to approximately
328 ft. (100 m) ahead, determines the cu rrent vehicle-to-veh icle following dis-
tance, and operates to maintain a suitab le following distance from the vehicle
ahead. The desired vehicle-to-vehicle distance can also be set by operating the
vehicle-to-vehicle distance switch. When driving on downhill slopes, the vehicl e-to-vehicle distance may become shorter.
Example of constant speed cruising
When there are no vehicles aheadThe vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appearsWhen a vehicle is detected running ahead of you, the system automatically decelerates
your vehicle. When a greater reduction in vehicle speed is necessary, the system applies
the brakes (the stop lights will come on at this time). The sy stem will respond to changes in
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by
the driver. Approach warning warns you when th e system cannot decelera te sufficiently to
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehi cle will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the “+RES” switch or depressing
the accelerator pedal (start-off operation) will resume follow -up cruising. If the start-off
operation is not performed, system contro l continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to a left lane while driving at
50 mph (80 km/h) or more, the vehicle will quickly accelerate to help to overtake a pass-
ing vehicle.

(  P.466)BSM (Blind Spot Monitor) *
The Blind Spot Monitor is a system
that uses rear side radar sensors
installed on the inner side of the
rear bumper on the left and right
side to assist the driver in confirm-
ing safety when changing lanes. WARNING■
Cautions regarding the use of the sys-
tem
The driver is solely responsible for safe
driving. Always driv e safely, taking care
to observe your surroundings.
The Blind Spot Monitor is a supplemen-
tary function which alerts the driver that a
vehicle is in a blind spot of the outside
rear view mirrors or is approaching rap-
idly from behind into a blind spot. Do not
overly rely on the Blind Spot Monitor. As
the function cannot judge if it is safe to
change lanes, over reliance could lead to
an accident resulting in death or serious
injury.
As the system may not function correctly
under certain conditions, the driver’s own
visual confirmation of safety is necessary.
