Driving
1Press the cruise control main switch
to activate the cruise control.
Radar cruise control indicator will come on
and a message will be displayed on the
multi-information display.
Press the switch again to deactivate the
cruise control.
If the cruise control ma in switch is pressed
and held for 1.5 seconds or more, the sys-
tem turns on in constant speed control
mode. ( P.210)
2 Accelerate or decelerate, with
accelerator pedal operation, to the
desired vehicle speed (at or above
approximately 30 mph [50 km/h])
and press the “-SET” switch to set
the speed.
Cruise control “SET” indicator will come
on.
The vehicle speed at the moment the
switch is released becomes the set speed.
If the switch is operated while the vehicle
speed is below approximately 30 mph (50
km/h) and a preceding vehicle is present,
the set speed will be adjusted to approxi- mately 30 mph (50 km/h).
To change the set speed, operate the
“+RES” or “-SET” switch until the
desired set speed is displayed.

Increases the speed
(Except when the vehicle has been
stopped by system control in vehicle-to-
vehicle distance control mode)
2Decreases the speed
Fine adjustment: Press the switch.
Large adjustment: Press and hold the
switch to change the speed, and
release when the desired speed is
reached.
In the vehicle-to-vehicle distance con-

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.
1Pressing 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.
However, when a vehicle ahead is not
detected, cruise control does not resume
when the vehicle speed is approximately 25 mph (40 km/h) or less.
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 appropriate vehi-
cle-to-vehicle distance.
■Warnings may not occur when
In the following instances, warnings
may not occur even when the vehicle-
to-vehicle distance is small.
When the speed of the preceding
vehicle matches or exceeds your
vehicle speed
When the preceding vehicle is trav-
eling at an extremely slow speed
Immediately after the cruise control
speed was set

pedal

2104-5. Using the driving support systems
When constant speed control mode is
selected, your vehicle will maintain a
set speed without controlling the vehi-
cle-to-vehicle distance. Select this
mode only when vehicle-to-vehicle dis-
tance control mode does not function
correctly due to a dirty radar sensor,
etc.
1With the cruise control off, press
and hold the cruise control main
switch for 1.5 seconds or more.
Immediately after the switch is pressed, the
radar cruise control in dicator will come on.
Afterwards, it switches to the cruise con-
trol indicator.
Switching to constant speed control mode
is only possible when operating the switch
with the cruise control off.
2 Accelerate or decelerate, with
accelerator pedal operation, to the
desired vehicle speed (at or above
approximately 25 mph [40 km/h])
and press the “-SET” switch to set
the speed.
Cruise control “SET” indicator will come
on.
The vehicle speed at the moment the
switch is released becomes the set speed.

P.209
■Dynamic radar cruise control with full-
speed range can be set when
●The shift position is in D.
●LC500: Range 4 or higher of D has been
selected by using the paddle shift switch.
●Vehicle speed is at or above approxi-
mately 30 mph (50 km/h).
However, when a preceding vehicle is
detected, the dynamic radar cruise con-
trol with full-speed range can be set even
if the vehicle speed is below approxi-
mately 30 mph (50 km/h).
■Accelerating after setting the vehicle
speed
The vehicle can accelerate by operating the
accelerator pedal. After accelerating, the
set speed resumes. Ho wever, during vehi-
cle-to-vehicle distance control mode, the
vehicle speed may decrease below the set
speed in order to main tain the distance to
the preceding vehicle.
■When the vehicle stops while follow-up
cruising
●Pressing the “+RES” switch while the
vehicle ahead stops wi ll resume follow-up
cruising if the vehicle ahead starts off
within approximately 3 seconds after the
switch is pressed.
●If the vehicle ahead starts off within 3 sec-
onds after your vehicle stops, follow-up
cruising will be resumed.
■Automatic cancelatio n of vehicle-to-
vehicle distance control mode
Vehicle-to-vehicle distance control mode is
automatically canceled in the following situ-
Selecting constant speed con-
trol mode

Driving
ations.
●Actual vehicle speed falls at or below
approximately 25 mph (40 km/h) when
there are no vehicles ahead.
●The preceding vehicle leaves the lane
when your vehicle is following at a vehicle
speed at or below approximately 25 mph
(40 km/h). Otherwise, the sensor can
not properly detect the vehicle.
(“CRUISE NOT AVAILABLE No Pre-
ceding Vehicles” is displayed on the
multi-information display)
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is
turned off.
●When snow mode is set.
●The sensor cannot detect correctly
because it is covered in some way.
●Pre-collision braking is activated.
●The parking brake is operated.
●The vehicle is stopped by system control
on a steep incline.
●The following are detected when the
vehicle has been stopped by system con-
trol:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes
If vehicle-to-vehicle distance control mode
is automatically canceled for any other rea-
son, there may be a malfunction in the sys-
tem. Contact your Lexus dealer.
■Automatic cancelation of constant
speed control mode
Constant speed control mode is automati-
cally canceled in the following situations:
●Actual vehicle speed is more than
approximately 10 mph (16 km/h) below
the set vehicle speed.
●Actual vehicle speed falls below approxi-
mately 25 mph (40 km/h).
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is turned off.
●Pre-collision braking is activated.
If constant speed control mode is automati-
cally canceled for any other reason, there
may be a malfunction in the system. Con-
tact your Lexus dealer.
■Brake system operation sound
If the brakes are app lied automatically while
the vehicle is in vehicle-to-vehicle distance
control mode, a brake system operation
sound may be heard. This does not indicate
a malfunction.
■If “Radar Cruise Control Unavailable” is
shown on the multi-information display
The radar cruise control system cannot be
used temporarily. Use the system when it
becomes available again.
■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.
■When the sensor may not be correctly
detecting the vehicle ahead
In the case of the fo llowing and depending
on the conditions, operate the brake pedal
when deceleration of the system is insuffi-
cient or operate the accelerator pedal
when acceleration is required.
As the sensor may not be able to correctly
detect these types of vehicles, the approach
warning ( P.209) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same
lane
●Vehicles with small rear ends (trailers
with no load on board, etc.)
