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

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.

Adjusting the set speed

2204-5. Using the driving support systems
After 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.
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

speed was set
 When depressing the accelerator
pedal
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.

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.

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

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

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.

used temporarily. Use the system when it
becomes available again.
■Warning messages and buzzers for
dynamic radar cruise control with full-

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

■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.220) may not be activated.
●Vehicles that cut in suddenly
