Dynamic laser cruise control (if equipped)
Dynamic laser cruise control supplements conventional cruise con-
trol with a vehicle-to-vehicle distan ce control. In the vehicle-to-vehi-
cle distance control mode, the vehicle automatically accelerates or
decelerates in order to maintain a set following distance from vehi-
cles ahead.
■ Set the vehicle speed
Press the “ON-OFF” button to
operate the cruise control.
Push the button once more to
deactivate.
Accelerate or decelerate to
the desired speed and press
the lever down to set.

■Selecting conventional constant speed control mode
Press the “ON-OFF” button
to operate the cruise con-
trol.
Switch to constant speed
control mode.
(Push and hold for approxi-
mately 1 second.)
Push the button once more to
deactivate.
Vehicle-to-vehicle distance
control mode is always reset
when the “ENGINE START
STOP” switch or the engine
switch is switched to ON
mode.
■ Adjusting the speed setting
Increase speed
Decrease speed
Hold the lever until the desired
speed setting is displayed.
In the constant speed control
mode, fine adjustment of the
set speed (approximately 1.0
mph [1.6 km/h]) can be made
by lightly pressing the lever up
or down and releasing it.

cancel cruise control.
The setting is also canceled
when depressing the brake
pedal.
Resume
To resume cruise control and
return to the set speed, push
the lever up.
■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
START STOP” switch or the
engine switch is set to the ON
mode.
A vehicle mark is displayed
ahead if one is detected. Preceding vehicle mark

AVALON_U_(L/O_0802)Example of follow-up cruising

When following a vehicle drivi ng 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 vehicles driving slower than the set
speed in the lane ahead
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.
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 buzzer will sound to alert the driver. An example of
this would be if another driver cuts in front of you while you are follow-
ing a vehicle. Apply the brake to ensure an appropriate vehicle-to-
vehicle distance.

■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.
The warning codes indicate the following.
If the same code appears again after implementing the correction procedure,
or if the cruise control cannot be set, contact your Toyota dealer.
■ 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 control mode.
Turn the system off by pressing the “ON-OFF” button, and turn it on again.

mittent operation.
• Avoid direct sunlight.
• Wait until the weather becomes clear.

■The dynamic laser cruise can be set when
● The shift lever is in “D” or the “4”, “5” or “6” range of “S” mode.
● Vehicle speed is between approximately 28 mph (45 km/h) and 85 mph
(135 km/h).
■ Accelerating
The vehicle can be accelerated normally.
■ Automatically canceling vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations.
● Vehicle speed falls below 25 mph (40 km/h)
● VSC is activated
● The sensor cannot operate correctly because it is covered in some way
Vehicle-to-vehicle distance control driving must be reset by turning the “ON-
OFF” button on again.
If vehicle-to-vehicle distance control driving 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 10 mph (16 km/h) below the preset
vehicle speed 
At this time, the memorized set speed is not retained.
● Vehicle speed falls below 25 mph (40 km/h)
● VSC is activated

■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
■ Approach warning
In the following instances, there is a possibility that the warning will not
occur.
● When the speed of the vehicle ahead matches or exceeds your vehicle’s
speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed has been set
● At the instant the accelerator is applied
■ Certification
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 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 21 C.F.R part
1040.10 and 1040.11.

CAUTION
■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 operating the dynamic laser cruise control by mistake
Keep the “ON-OFF” button off 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 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
● 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, snow, sandstorm, etc.)
● When the approach warning buzzer can be heard often

NOTICE
■Handling the laser radar sensor
Observe the following to ensure the cruise control system can function effec-
tively.
● 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.
