■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.

■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
■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. 168) will not be activated, and an accident may
result.
● 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
■ 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 an 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
trunk 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.

NOTICE
■To ensure the laser radar  sensor functions correctly
Do not do the following to the sensor or grille cover as doing so may cause
the sensor not to function correctly and could result in an accident.
● Stick or attach anything to them
● Leave them dirty
● Disassemble or subject them to strong shocks
● Modify or paint them
● Replace them with non-genuine parts
■ 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.
● Do not modify or paint the sensor.

CAUTION
■While driving
Do not adjust the display.
Be sure to adjust the display only when the vehicle is stopped.
■ When doing the circling calibration
Be sure to secure a wide space, and watch out for people and vehicles in the
neighborhood. Do not violate any local traffic rules while performing circling
calibration.
NOTICE
■To avoid the compass malfunctions
Do not place magnets or any metal objects near the inside rear view mirror. 
Doing this may cause a malfunction of the compass sensor.
■ To ensure normal operation of the compass
● Do not perform circling calibration of the compass in a place where the
earth’s magnetic field is subject to inte rference by artificial magnetic fields.
● During calibration, do not operate electric systems (moon roof, power win-
dows, etc.) as they may interfere with the calibration.

AVALON_U_OM41430U
Event data recorder
In a crash or a near car crash eventThe SRS airbag sensor assembly contains the EDR. In a crash or a
near car crash event, this device may record some or all of the follow-
ing information:
● Engine speed
● Whether the brake pedal was applied or not
● Vehicle speed
● To what extent the accelerator pedal was depressed
● Position of the transmission shift lever
● Whether the driver and front passenger wore seat belts or not
● Driver’s seat position
● Front passenger’s occupant classification
● SRS airbag deployment data
● SRS airbag system diagnostic data
The information above is intended  to be used for the purpose of
improving vehicle safety performance. Unlike general data recorders,
the EDR does not record sound data such as conversation between
passengers.
Your vehicle has computers that monitor and control certain aspects
of your vehicle. These computers assi st in driving and maintaining
optimal vehicle performance.
Besides storing data useful for tr oubleshooting, there is a system to
record data in a crash or a near  car crash event. This is called an
Event Data Recorder (EDR).
