■Changing the vehicle -to-vehicle distance
Each push of the switch
changes the vehi cle-to-vehicle
distance.
Long
Medium
Short
The vehicle-to-vehicle distance
is automatically set to the long
mode when the engine switch
is turned to the ON position.
A vehicle symbol will be dis-
played to indicate the presence
of the vehicle if a vehicle is
running ahead of you.

202 2-4. Using other driving systems
Driving in vehicle-to-vehicle distance control modeThis mode employs a laser radar sensor to detect the presence of
vehicles within 400 ft. (120 m) ahead and to judge the distance
between your vehicle and those vehicles.
Note that vehicle-to-vehicle distance will close when traveling on long
downhill slopes.
Example of constant speed cruising (when there are no vehicles
ahead):
When set to 62 mph (100 km/h)
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance switch.
Example of deceleration cruising (when the vehicle ahead is driv-
ing slower than the set speed):
When fixed speed cruising is set at 62 mph (100 km/h) and the
vehicle ahead is driving at 50 mph (80 km/h)
When a vehicle is detected running ahead of you, in the same lane, the
system automatically decelerates your vehicle. When a greater reduction
in vehicle speed is necessary, the system applies the brakes. A warning
tone warns you when the system cannot decelerate sufficiently to prevent
your vehicle from closing on the vehicle ahead.

When driving
Example of follow-up cruising (when following a vehicle driving
slower than the set speed):
When the speed is set to 62 mph (100 km/h) and the vehicle ahead
is driving at 50 mph (80 km/h)
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 vehicles driving
slower than the set speed in the lane ahead):
When the speed is set to 62 mph (100 km/h) and the vehicle ahead
driving at 50 mph (80 km/h) is out of the lane
When the vehicle ahead of you executes a lane change, the system
slowly accelerates until the set vehicle speed is reached. The system then
returns to fixed speed cruising.
■Fine adjustment of the set speed
Adjustment of the set speed by the following speed can be made by lightly
pressing the lever up or down and releasing it.
In the constant speed control mode: Approximately 1.0 mph (1.6 km/h)
In the vehicle-to-vehicle distance control mode:U.S.A.: Approximately 5 mph (8 km/h)
Canada: Approximately 3 mph (5 km/h)
■ Dynamic laser cruise control warning lights, display and buzzers
Warning lights, display and buzzers are used to indicate a system malfunc-
tion or to alert you to the need for caution while driving. ( P. 595)
■ The dynamic laser cruise can be set when
●The shift lever is in D or the shift range position must be in between 4 and
6 in S mode.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Accelerating
The vehicle can be accelerated normally.

204 2-4. Using other driving systems
■Automatically canceling vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations.
●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.
*: 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.
■ Automatically canceling constant speed control
The set speed is automatically canceled in the following situations.
●Actual vehicle speed is more than approximately 10 mph (16 km/h)
below the preset 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.
■ 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.
Distance optionsVehicle-to-vehicle distance
Long Approximately 245 ft. (75 m)
Medium Approximately 165 ft. (50 m)
Short Approximately 100 ft. (30 m)

■ Certification
CAUTION
■To avoid bodily injury
●Do not look into the aperture window.
● Use of controls or adjustment or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
■ Before using dynamic laser cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set vehicle 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.
■ To avoid inadvertent cruise control activation
Turn off the system when not in use.
Always keep the sensor clean to ensure
that the vehicle-to-vehicle distance con-
trol operates properly. (Some obstruc-
tions, such as snow, ice or 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 l laser product complied with 21C.F.R part 1040.10
and 1040.11.

206 2-4. Using other driving systems
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 control of speed and could cause seri-
ous or fatal accident.
●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
● 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.)
● Where buzzer can be heard often
● When your vehicle is towing anything
■ When the laser radar 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 proximity alarm ( P. 592) will not be activated, and an 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.
