you, the preceding vehicle
mark will also be displayed.
■Canceling and resuming the speed control
Pulling the lever toward you
cancels the cruise control.
The speed setting is also can-
celed when the brakes are
applied.
Pushing the lever up
resumes the cruise control
and returns vehicle speed
to the set speed.
Resuming is available when
the vehicle speed is more than
approximately 25 mph (40
km/h).

Example of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration
When there are no longer any vehi cles ahead driving slower than
the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient
automatic deceleration via the cruise control is not possible, the dis-
play will flash and the bu zzer will sound to alert the driver. An exam-
ple of this would be if another driver cuts in front of you while you are
following a vehicle. Apply the brakes to ensure an appropriate vehi-
cle-to-vehicle distance.

■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
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.

■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)
■ Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances shown corre-
spond to a vehicle speed of 55 mph (90 km/h). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed.
■ Laser radar sensor
Distance optionsVehicle-to-vehicle distance
Long Approximately 245 ft. (75 m)
Medium Approximately 165 ft. (50 m) Short Approximately 100 ft. (30 m)
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.

216 2-4. Using other driving systems
■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. 613)
■ Approach warning
In the following instances, there is a possibility that the warnings will not
occur:
●When the speed of the vehicle ahead matches or exceeds your vehicle
speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed was set
● At the instant the accelerator is applied
■ Certification
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.
This product is a class I laser product complied with 21C.F.R part 1040.10
and 1040.11.

CAUTION
■Cautions regarding the driving assist systems
●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.
■ 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 and 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

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.

294 2-5. Driving information
CAUTION
■To avoid accident or injury
●Do not apply the brakes suddenly as you may skid, resulting in jackknifing
and loss of vehicle control. This is especially true on wet or slippery sur-
faces.
● Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue weight capacities.
● Do not use cruise control when towing.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts while descending steep or long
downhill grades.
● Vehicle-trailer instability is more likely on steep long downhills. Before
descending steep or long downhill grades, slow down and downshift. Do
not make sudden downshifts when descending steep or long downhill
grades. Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and result
in reduced braking efficiency.
● Do not tow a trailer when the temporary spare tire is installed on your vehi-
cle.
■ Hitch
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine the maximum weight
rating of the particular hitch assembly and never exceed the maximum
weight rating specified for the trailer-hitch. Exceeding the maximum weight
rating set by the trailer-hitch manufacturer can cause an accident resulting in
death or serious personal injuries.
■ When towing a trailer
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
●If the gross trailer weight exceeds unbraked TWR, trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.
