■Dynamic laser cruise control warnings
If a system malfunction is detected, dynamic laser cruise control master
warning light comes on, the “CRUISE” indicator light flashes, the buzzer
sounds, and a warning code appears on the display 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.

tem is unable to judge
the vehicle-to-vehicle
distance.• Stop the wipers or
switch the wiper
switch to intermittent
operation.
• Avoid direct sunlight.
• Wait until the weather becomes clear.

When driving
■The dynamic laser cruise can be set when
●The shift lever is in D or 4.
● Vehicle speed is between the following speed.
U.S.A.: Approximately 28 mph (45 km/h) - 85 mph (137 km/h)
Canada: Approximately 45 km/h (28 mph) - 139 km/h (86 mph)
■ 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.
*
●The windshield wipers are operating at high or low speed.*
*
: 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 cancelling fixed 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 (88 km/h). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed.
■ Laser radar sensor
■ Certification
This product is a class I laser product complied with 21 C.F.R part 1040. 10
and 1040. 11.
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.

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. 204) 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 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
■ To ensure the laser rada r sensor functions correctly
Do not do the following to the sensor as doing so may cause the sensor not
to function correctly and could result in an accident.
● Stick or attach anything to it
● Leave it dirty
● Disassemble, subject it to strong shocks
● Modify or paint it
● Replace it with non-genuine parts

Intuitive parking assist (if equipped)
The distance to obstacles measured by the sensors is communi-
cated via the indicator and a buzzer when parallel parking or maneu-
vering into a garage. Always check the surrounding area when using
this system.

Detection range of the sensorsApproximately 2.0 ft. (60 cm)
Approximately 2.8 ft. (85 cm)
Approximately 5.9 ft. (180 cm)
The diagram shows the detection
range of the sensors. Note that
the sensors cannot detect obsta-
cles that are extremely close to
the vehicle.
The range of the sensors may
change depending on the shape
of the object etc.
