Driving
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not pe rformed, system
control continues to keep your vehicle stopped.
When the turn signal lever is ope rated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will accel-
erate to help to overt ake a passing vehicle.
The system’s identification of what is an overtaking lane may be determined
solely based on the location of the steering wheel in the vehicle (left side
driver position versus right side driver position.) If the vehi cle is driven to a
region where the overtaking lane is on a different side from wh ere the vehi-
cle is normally driven, the vehicle may accelerate when the tur n signal lever
is operated in the opposite direction to the overtaking lane (e .g., if the driver
normally operates the vehicle in a region where the overtaking lane is to the
right but then drives to a region where the overtaking lane is to the left, the

as follows:
Fine adjustment: By 1 mph (1.6
km/h)
*1 or 1 km/h (0.6 mph)*2 each
time the switch is pressed
Large adjustment: The speed will
continue to change while the switch is held.

“MPH”
*2: When the set speed is shown in “km/h”
■Increasing the set speed by

pedal operation to the
desired vehicle speed
2 Press the “-SET” switch

any reasons other than the above,
there may be a malfunction in the
system. Contact your Toyota dealer.
■Automatic cancelation of con-
stant speed control mode
Constant speed control mode is
automatically cance led in the follow-
ing situations:
●Actual vehicle speed is more than
approximately 10 mph (16 km/h)
below the set vehicle speed.
●Actual vehicle speed falls below
approximately 20 mph (30 km/h).
●VSC is activated.
●TRAC is activated for a period of
time.
●When the VSC or TRAC system is
turned off.
●When the brake control or output
restriction control of a driving sup-
port system operates. (For exam-
ple: Pre-Collision System, Drive-
Start Control)
●The center differential lock/unlock
is not completed within 5 seconds
while the cruise con trol system is
on.
●The parking brake is operated.
If constant speed control mode is
automatically canceled for any rea-
sons other than the above, there
may be a malfunction in the system.
Contact your Toyota dealer.
■Brake operation
A brake operation sound may be
heard and the brake pedal response
may change, but the se are not mal-
functions.
■Warning messages and buzzers
for dynamic radar cruise con-
trol with full-speed range
Warning messages and buzzers are
used to indicate a system malfunc-
tion or to inform the driver of the
need for caution while driving. If a
warning message is shown on the
multi-information display, read the
message and follow the instruc- tions.(
P.228, 511)
■When the sensor may not be
correctly detecting the vehicle
ahead
In the case of the following and
depending on the conditions, oper-
ate the brake pedal when decelera-
tion of the system is insufficient or
operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to
correctly detect th ese types of vehi-
cles, the approach warning
( P.263) 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.)
●Motorcycles traveling in the same
lane
●When water or snow thrown up by
the surrounding vehicles hinders
the detecting of the sensor
●When your vehicle is pointing
upwards (caused by a heavy load
in the luggage compartment, etc.)
●Preceding vehicle has an
extremely high ground clearance

■Auto Trailer Detection (ATD)
Auto Trailer Detection (ATD) detects
if a trailer is atta ched by using the
Trailer Brake Controller (TBC) or the
Blind Spot Monitor (BSM) sensors.
●Trailers that use TBC can be
detected by using the 7-pin trailer
brake connectors.
●Other types of trailers can be
detected using the BSM sensors.
●When a trailer is detected via BSM
or TBC, RCTA function will be dis-
abled.
●As soon as the trailer is detected,
the detection area will be
extended to a maximum length of
approximately 16 ft. (15 m) from
the rear bumper of the truck.
●If the trailer does not have a 7-pin
connector, or the 7-pin connector
is not engaged, the trailer is
detected via the BSM sensor. In
this case PKSB and Intuitive park-
ing assist functio ns will not be dis-
abled.
●For trailer auto d etection without
engagement of 7-pin connector,
the vehicle should be moving for-
ward at speed of above 0.6 mph
(1 km/h) for at l east 10 seconds.
●ATD function is triggered at every
power switch on/of f cycle or if the
vehicle is stopped in shift the shift
lever is in P or N for more than 90
seconds.
●Trailer detection vis BSM sensors
may be delayed if the vehicle is in

connected.

●Do not modify the sensor or sur-
rounding area on the rear
bumper.

or replaced, contact your Toyota
dealer.
