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.

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.

208 2-4. Using other driving systems
CAUTION
■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 them
● Leave them dirty
● Disassemble, subject them to strong shocks
● Modify or paint them
● Replace them with non-genuine parts
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.

214 2-4. Using other driving systems
■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected. Objects lower than the sensors or thin stakes etc. may be detected ini-
tially, but as they draw closer, they may cease to be detected.
• A towing hitch is mounted to the vehicle.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• When attaching a two-way radio antenna.
• When a towing eyelet is mounted on your vehicle.
• When the bumper is damaged.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by a sensor to be closer
than they are.
● The shape of the obstacle may prevent a sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles

■Rear view monitor system camera
■ Smear effect
The rear view monitor system camera is
located on the back door as shown in the
illustration.
In the following cases, it may become dif-
ficult to see the images on the screen,
even when the system is functioning cor-
rectly.
●The vehicle is in a dark area, such
as at night.
● The temperature near the lens is
extremely high or low.
● Water droplets are on the camera
lens or humidity is high, such as
when it rains.
● Foreign matter, such as snow or
mud, adheres to the camera lens.
● The sun or headlights are shining
directly into the camera lens.
● A bright object such as a white wall
is reflected in the mirror surface
over the monitor.
● When the camera has scratches or
dirt on it.
If a bright light, such as sunlight
reflected off the vehicle body, is picked
up by the camera, a smear effect* char-
acteristic to the camera may occur.
*: Smear effect A phenomenon that
occurs when a bright light is picked
up by the camera; when transmitted
by the camera, the light source
appears to have a vertical streak
above and below it.
