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. 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.
■ When the vehicle stops while follow-up
cruising
● Pressing the “+RES” switch while the
vehicle ahead stops will 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 cancelation of vehicle-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 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 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.
■ 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.
