Selecting conventional cons tant speed control mode
Constant speed control mode differ s from vehicle-to-vehicle distance
control mode. When constant spee d control mode is selected, your
vehicle will maintain a set speed regardless of whether or not there
are other vehicles in the lane ahead.
Press the ON-OFF button to
activate the cruise control.
Press the button again to deacti-
vate the cruise control.
Switch to constant speed con-
trol mode.
(Push the lever forward and
hold for approximately one
second.)
Constant speed control mode
indicator will come on.
When in constant speed control
mode, to return to vehicle-to-vehi-
cle distance control mode, push
the lever forward again and hold
for approximately 1 second.
After the desired speed has been
set, it is not possible to return to
vehicle-to-vehicle distance con-
trol mode.
If the engine switch is turned off
and then turned to the ON posi-
tion again, the vehicle will auto-
matically return to vehicle-to-
vehicle distance control mode.

■Dynamic laser cruise control can be set when
●The shift lever is in the D or range 4 or higher of S has been selected.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-
vehicle distance control mode has been used. The mode also cannot be
switched from constant speed control to vehicle-to-vehicle distance control
mode. Turn the system off by pressing the ON-OFF button, and turn it on
again.
■ Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed
resumes. However, during vehicle-to-vehicle distance control mode, the
vehicle speed may decrease below the set speed in order to maintain the
distance to the vehicle ahead.
■ Automatic cancelation of vehicle -to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations:
● Actual vehicle speed falls below approximately 25 mph (40 km/h)
● VSC is activated
● The sensor cannot operate correctly because it is covered in some way.
*
●The windshield wipers are operating at high or low speed.*
●The operation cannot be switched for 5 seconds or more after operating
the front wheel drive control switch or the center differential lock switch.
(4WD models)
*: Vehicle-to-vehicle distance control driving must be reset by pressing the
ON-OFF button again.
If vehicle-to-vehicle distance control dr iving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

When driving
■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following sit-
uations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h)
below the set vehicle speed
At this time, the memorized set speed is not retained.
● Vehicle speed falls below approximately 25 mph (40 km/h)
● VSC is activated
● The operation cannot be switched for 5 seconds or more after operating
the front wheel drive control switch or the center differential lock switch.
(4WD models)
■ Laser radar sensor
■ Warning lights, messages and buzzers for dynamic laser cruise control
Warning lights, messages and buzzers are used to indicate a system mal-
function or to inform the driver of the need for caution while driving.
(P. 568)
■ Certification
Always keep the sensor clean to ensure
that the vehicle-to-vehicle distance con-
trol operates properly. (Some obstruc-
tions, such as snow, ice and plastic
objects, cannot be detected by the
obstruction sensor.)
Dynamic laser cruise control is canceled
if an obstruction is detected.
This product is a class I laser product complied with 21C.F.R part 1040.10
and 1040.11.

214 2-4. Using other driving systems
CAUTION
■Before using dynamic laser cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not
appropriate, adjust the vehicle speed, as well as the distance between your
vehicle and vehicles ahead by applying the brakes etc.
■ Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure following distance
The dynamic laser cruise control is only intended to help the driver in
determining the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead. It is not a mechanism that allows care-
less or inattentive driving, and it is not a system that can assist the driver in
low-visibility conditions. It is still necessary for driver to pay close attention
to the vehicle’s surroundings.
● Assisting the driver to judge proper following distance
The dynamic laser cruise control determines whether the following dis-
tance between the driver’s own vehicle and a designated vehicle traveling
ahead is appropriate or not. It is not capable of making any other type of
judgement. Therefore, it is absolutely necessary for the driver to remain
vigilant and to determine whether or not there is a possibility of danger in
any given situation.
● Assisting the driver to operate the vehicle
The dynamic laser cruise control has no capability to prevent or avoid a
collision with a vehicle traveling ahead. Therefore, if there is ever any dan-
ger, the driver must take immediate and direct control of the vehicle and
act appropriately in order to ensure the safety of all involved.
■ To avoid inadvertent cruise control activation
Switch the cruise control off using the ON-OFF button when not in use.

When driving
CAUTION
■Situations unsuitable for dynamic laser cruise control
Do not use dynamic laser cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
●In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
● At entrances to expressways
● When weather conditions are bad enough that they may prevent the sen-
sors from functioning correctly (fog, rain, snow, sandstorm, direct sunlight,
etc.)
● When an approach warning buzzer is heard often
● When your vehicle is towing a trailer or during emergency towing

216 2-4. Using other driving systems
CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning ( P. 568) will not be activated, and a fatal or serious
accident may result.
● The vehicle ahead has higher ground clearance, which means that the
placement of the reflectors is in a higher position.
● The rear section of the vehicle ahead is extremely dirty.
● The vehicle ahead or other vehicles around you are flinging up water or
snow.
● Excessive exhaust gas (black smoke) is coming from the vehicle ahead or
other vehicles around you, obscuring your front view.
● There is an obstruction (protective film, sticker, etc.) on the reflectors on
the vehicle ahead, or reflectors are not installed on the vehicle ahead or
are damaged.
● Heavy luggage in the luggage compartment or rear seats is causing the
nose of your vehicle to tilt up.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving
● Vehicles with small rear ends (trailers with no load on board etc.)
● Motorcycles traveling in the same lane

CAUTION
■Conditions under which the vehicle -to-vehicle distance control may
not function correctly
Apply the brakes as necessary in the following conditions as the laser radar
sensor may not be able to correctly detect vehicles ahead, and a fatal or
serious accident may result.
● When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
● When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
● When the road curves or when the lanes are narrow
● When steering wheel operation or your position in the lane is unstable
● When the vehicle ahead of you decelerates suddenly
● When your vehicle is towing a trailer or during emergency towing
■ Handling the laser radar sensor
Observe the following to ensure the cruise control system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an acci-
dent.
●Keep the sensor clean at all times.
Clean the sensor with a soft cloth so you do not mark or damage them.
● Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction.
If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by a Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, surrounding area.
● Do not modify or paint the sensor.
● Do not replace them with non-genuine parts.

Intuitive parking assist
: If equipped
The intuitive parking assist is designed to inform you of the approxi-
mate distance between your vehicle and an obstruction by indicator
and buzzer when parking the veh icle. This system uses sensors to
detect obstructions.
This system works when the engine switch is in the ON position and
the shift lever is not in P.
Back and rear corner sensors work only when the shift lever is in
R.
Front corner sensors work when:
● The shift lever is in R
● The shift lever is not in P or R and vehicle speed is approximate
6 mph (10 km/h) or less.
