●
The shift lever is in D.

by using the paddle shift switch.
●
Vehicle speed is at or above approxi-
mately 50 km/h (30 mph).
■
Accelerating after setting the vehicle
speed
The vehicle can accelerate by operating the
accelerator pedal. After accelerating, the
set speed resumes. However, during vehi-
cle-to-vehicle distance control mode, the
vehicle speed may decrease below the set
speed in order to maintain the distance to
the preceding vehicle.
■
Automatic cancelation of vehi-
cle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is
automatically canceled in the following situ-
ations:
●
Actual vehicle speed falls at or below
approximately 40 km/h (25 mph).
●
VSC is activated.
●
TRC is activated for a period of time.
●
When the VSC or TRC system is turned
off.
●
The sensor cannot detect correctly
because it is covered in some way.
●
Pre-collision braking is activated.
If vehicle-to-vehicle distance control mode
is automatically canceled for any other
reason, there may be a malfunction in the
system. 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 16 km/h (10 mph) below
the set vehicle speed.
●
Actual vehicle speed falls below approxi-
mately 40 km/h (25 mph).
●
VSC is activated.
●
TRC is activated for a period of time.
●
When the VSC or TRC 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 applied 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.
■
Warning messages and buzzers for
dynamic radar cruise control
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 message is shown on the
multi-information display, read the message
and follow the instructions.
■
When the sensor may not be correctly
detecting the vehicle ahead
In the case of the following 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.212) may not be activated.
