Temporary cancellation of functions
When operation conditions are no longer met, a function may be temporarily
canceled. However, when the operation conditions are met again, operation
of the function is automatically restored. ( P. 281)
■ Steering control function
Depending on the vehicle speed, lane departure situation, road conditions,
etc., the driver may not feel the function is operating or the function may not
operate at all.
■ Lane departure alert function
The warning buzzer may be difficult to hear due to external noi se, audio play-
back, etc.
■ Hands off steering wheel alert
When the system determines that the driver has removed the hand s from the
steering wheel while the steering control function is operating , a warning
message is displayed on the multi-information display.
If the driver continues to keep the hands off of the steering wheel, a buzzer
sounds, a warning message is displayed. This alert also operates in the same
way when the driver continuously operates the steering wheel on ly a small
amount. However, depending on the road conditions, etc., the function may
not cancel.
■ White (yellow) lines are only on one side of road
The LDA system will not operate for the side on which white (yellow) lines
could not be recognized.

● The vehicle is driven on an unpaved or rough road.
● The vehicle is driven around a sharp curve.
● The traffic lane is excessively narrow or wide.
● The vehicle is extremely tilted due to carrying heavy luggage or having
improper tire pressure.
● The distance to the preceding vehicle is extremely short.
● The vehicle is moving up and down a large amount due to road co nditions
during driving (poor roads or road seams).

beam axis has deviated.
● The vehicle is struck by a crosswind.
● The vehicle has just changed lanes or crossed an intersection.
● Snow tires, etc. are equipped.

Warning message
Warning messages are used to indicate a system malfunction or to inform the
driver of the need for caution while driving. ( P. 581)
■ Customization
Some settings can be changed.

Driving
HIGHLANDER_U (OM0E031U)
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates and decelerates to match the speed changes of the p re-
ceding vehicle even if the accelerator pedal is not depressed. In con-
stant speed control mode, t he vehicle runs at a fixed speed.
Use the dynamic radar cruise c ontrol on freeways and highways.

WARNING
■Before using dynamic r adar cruise control
Driving safely is the sole responsibility of the driver. Do not rely solely on the
system, and drive safely by always paying careful attention to your sur-
roundings.
The dynamic radar cruise control provides driving assistance to reduce the
driver's burden. However, there are limitations to the assistan ce provided.
Set the speed appropriately depending on the speed limit, traff ic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condi tion
observed by the driver. Therefore, the driver must always remai n alert,
assess the danger of each situation and drive safely. Relying o n this system
or assuming the system ensures safety while driving can lead to an acci-
dent, resulting in death or serious injury.
■ Cautions regarding the driving assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident resulting in death or se rious injury.
● Assisting the driver to measure following distance
The dynamic radar cruise control is only intended to help the d river in
determining the following distance between the driver’s own veh icle and a
designated vehicle traveling ahead. It is not a mechanism that allows care-
less or inattentive driving, and it is not a system that can as sist the driver in
low-visibility conditions. It is still necessary for driver to pay close attention
to the vehicle’s surroundings.
● Assisting the driver to judge proper following distance
The dynamic radar cruise control determines whether the followi ng dis-
tance between the driver’s own vehicle and a designated vehicle traveling
ahead is within a set range. It is not capable of making any ot her type of
judgement. Therefore, it is absolutely necessary for the driver to remain
vigilant and to determine whether or not there is a possibility of danger in
any given situation.
● Assisting the driver to operate the vehicle
The dynamic radar cruise control has limited capability to prev ent or avoid
a collision with a vehicle traveling ahead. Therefore, if there is ever any
danger, the driver must take immediate and direct control of th e vehicle
and act appropriately in order to ensure the safety of all involved.
■ To avoid inadvertent dynamic r adar cruise control activation
Switch the dynamic radar cruise control off using the “ON-OFF” button
when not in use.

WARNING
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could ca use an acci-
dent resulting in death or serious injury.
● Roads where there are pedestrians, cyclers, etc.
● 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 s harp up
and down gradients
Vehicle speed may exceed the set speed when driving down a stee p hill.
● At entrances to freeways and highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When there is rain, snow, etc. on the front surface of the radar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● When your vehicle is towing a trailer or during emergency towin g
● When an approach warning buzzer is heard often

2884-5. Using the driving support systems
HIGHLANDER_U (OM0E031U)
This mode employs a radar sensor to detect the presence of vehi cles
up to approximately 320 ft. (100 m) ahead, determines the curre nt
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
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-ve hicle dis-
tance switch.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate su ffi-
ciently to prevent your vehicle fr om closing in on the vehicle ahead.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The syst em then
returns to constant speed cruising.
