DrivingAfter the vehicle ahead of you starts
off, press the “+RES” switch.
Your vehicle will also resume follow-
up cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.1
Pressing the cancel switch cancels
the speed control.
The speed control is also canceled when
the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depressing the brake pedal
does not cancel the setting.)
2Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.
When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the
driver. An example of this would be if
another driver cuts in front of you while
you are following a vehicle. Depress
the brake pedal to ensure an appropri-
ate vehicle-to-vehicle distance.

the system. Contact your Lexus dealer.
■Brake operation
A brake operation sound may be heard and
the brake pedal response may change, but
these are not malfunctions.
■Warning messages and buzzers for
dynamic radar cruise control with full-
speed range
Warning messages and buzzers are used to
indicate a system malfunction or to inform
the driver of the need for caution while driv-
ing. If a warning messa ge is shown on the
multi-information displa y, read the message
and follow the instructions. ( P.175, P.371)

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
function
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 nec-
essary.
