Driving
HIGHLANDER_U (OM48E98U)
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 400 ft. (120 m) ahead, determines the current
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-vehicle dis-
tance control.
Example of deceleration cruising
When the vehicle ahead is drivi ng slower than the set speed
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes. A warning tone warns you when
the system cannot decelerate sufficiently to prevent your vehicle from clos-
ing in on the vehicle ahead.

■Dynamic radar cruise control can be set when
●The shift lever is in the D or range 4 or higher of S has been selected.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed
resumes. However, during vehicle-to-vehicle distance control mode, the vehi-
cle speed may decrease below the set speed in order to maintain the dis-
tance to the vehicle ahead.
■ Automatic cancelation of vehic le-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the fol-
lowing situations:
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● Enhanced VSC is activated.
● VSC is activated.
● The sensor cannot operate correctly because it is covered in some way.
● The windshield wipers are operating at high speed (when the wiper switch is
set to the high speed wiper operation position).
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.
■ Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situ-
ations:
● Actual vehicle speed is more than approximately 10 mph (16 km/h) below
the set vehicle speed.
At this time, the memorized set speed is not retained.
● Vehicle speed falls below approximately 25 mph (40 km/h).
● Enhanced VSC is activated.
● VSC is activated.

Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-
vehicle distance control operates properly. (Some obstructions, such as
snow, ice and plastic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
■ Operation guide display
When the dynamic radar cruise control switch is operated, a guidance display
is shown on the multi-information display for a few seconds as to how to oper-
ate the dynamic radar cruise control switch or distance switch. ( P. 105)
■ Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. ( P. 579)

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 cause an acci-
dent resulting in death or serious injury.
● 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
Vehicle speed may exceed the set speed when driving down a steep hill.
● At entrances to expressways
● When weather conditions are bad enough that they may prevent the sen-
sors from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
● When an approach warning buzzer is heard often
● When your vehicle is towing a trailer or during emergency towing
■ When the sensor may not be correct ly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicle\
s
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning ( P. 272) will not be activated, and a fatal or serious
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

WARNING
■Conditions under which the vehicle-to-vehicle distance control may
not function correctly
Apply the brakes as necessary in the following conditions as the radar sen-
sor may not be able to correctly detect vehicles ahead, and a fatal or seri-
ous 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
● When the vehicle ahead of you decelerates suddenly
■ Handling the radar sensor
Observe the following to ensure the cruise control system can function
effectively.
Otherwise, the system may not function correctly and could result in an
accident.
● Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover 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 your Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
● Do not modify or paint the sensor and grille cover.
● Do not replace them with non-genuine parts.

HIGHLANDER_U (OM48E98U)
While driving on a road that has la ne markers, this system recognizes
the lane markers using a camera as a sensor to alert the driver when
the vehicle deviates from its lane.
If the system judges that the vehicle has deviated from its lane, it
alerts the driver using a buzzer and indications on the multi-informa-
tion display.

■Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
●The turn signal lever is operated.
● The vehicle speed deviates from the operating range of the LDA system
functions.
● When the lane lines cannot be recognized while driving.
● When the lane departure warning function is activated.
The lane departure warning function will not operate again for a several sec-
onds after it has been activated, even if the vehicle leaves the lane again.
■ The lane departure warning
Depending on the audio system sound level or air conditioning fan noise
while the audio system or air conditioning system is in use, it may be difficult
to hear the warning sound.
■ After the vehicle has been parked in the sun
The LDA system may not be available and a warning message ( P. 579) will
be displayed for a while after driving has started. When the temperature in the
cabin decreases and the temperature around the camera sensor ( P. 280)
becomes suitable for its operation, the functions will begin to operate.
■ If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane mark-
ers could not be recognized.

Conditions in which the function may not operate correctly
In the following situations, the camera sensor may be unable to recognize
lane markers causing the lane departure warning function to operate incor-
rectly. However, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a
crossing or before a ticket checkpoint
● When driving on a sharp curve
● When lane markers are extremely narrow or extremely wide
● When the vehicle leans to one side an unusual amount due to a heavy load
or improper tire inflation pressure
● When the following distance between your vehicle and the vehicle ahead is
extremely short
● When the lane markers are yellow (These may be more difficult for the sys-
tem to recognize compared to white markers.)
● When the lane markers are broken, Botts’ dots (raised pavement markers)
or stones
● When the lane markers are on a curb etc.
● When lane markers are obscured or partially obscured by sand, dirt, etc.
● When there are shadows on the road running parallel with lane markers, or
if a shadow covers the lane markers
● When driving on a particularly bright road surface, such as concrete
● When driving on a road surface that is bright due to reflected light
● When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel
● When sunlight or the headlights of oncoming vehicles are shining directly
into the camera lens
● When driving on roads that are branching or merging
● When driving on a road surface that is wet due to rain, previous rainfall,
standing water, etc.
● When the vehicle experiences strong up-and-down motion such as when
driving on an extremely rough road or on a seam in the pavement
● When headlight brightness at nighttime is reduced due to dirt on the lenses,
or when the headlights are misaligned
● When driving on winding roads or roads that are uneven
● When driving on rough or unpaved roads
