■Conditions to turn the high beams on/off automatically
●When all of the following conditions are met, the high beams will be turned  
on automatically (after approximately  1 second):• The vehicle speed is approximately 30  
km/h (19 mph) or more. • The area ahead of the vehicle is dark.• There are no vehicles ahead with  
headlights or tail lights turned on. • There are few streetlights on the road ahead.
●If any of the following conditions are met, the high beams will turn off auto- 
matically: • The vehicle speed is below approxi-mately 25 km/h (16 mph). 
• The area ahead of the vehicle is not  dark.• Vehicles ahead have their headlights  
or tail lights turned on. • There are many streetlights on the road ahead.
■Front camera detection information
●The high beams may not be automati-cally turned off in the following situa- 
tions: • When a vehicle suddenly appears from around a curve 
• When the vehicle is cut in front of by  another vehicle 
• When vehicles ahead cannot be  
detected due to repeated curves, road  dividers or roadside trees• When vehicles ahead appear in a far- 
away lane on a wide road • When the lights of vehicles ahead are not on
●The high beams may be turned off if a vehicle ahead that is using fog lights  
without its headlights turned on is  detected.
●House lights, streetlights, traffic sig-nals, and illuminated billboards or signs and other reflective objects may  
cause the high beams to change to  the low beams, or the low beams to remain on.
●The following factors may affect the amount of time taken for the high  
beams to turn on or off: • The brightness of the headlights, fog lights, and tail lights of vehicles ahead 
• The movement and direction of vehi- cles ahead• When a vehicle ahead only has oper- 
ational lights on one side • When a vehicle ahead is a two-wheeled vehicle 
• The condition of the road (gradient,  curve, condition of the road surface, etc.) 
• The number of passengers and  amount of luggage in the vehicle
●The high beams may turn on or off unexpectedly.
●Bicycles or similar vehicles may not be detected.
●In the following situations the system may not be able to correctly detect the surrounding brightness level. This  
may cause the low beams to remain  on or the high beams to flash or daz-zle pedestrians or vehicles ahead. In  
such a case, it is necessary to manu- ally switch between the high and low beams.

WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys- 
tem. The LTA system does not  automatically drive the vehicle or reduce the amount of attention that  
must be paid to the area in front of  the vehicle. The driver must always assume full responsibility for driving  
safely by paying careful attention to  the surrounding conditions and operating the steering wheel to cor- 
rect the path of the vehicle. Also,  the driver must take adequate breaks when fatigued, such as from  
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful  attention may lead to an accident, resulting in death or serious injury.
■Situations unsuitable for LTA system 
In the following situations, use the  LTA switch to turn the system off. Fail-ure to do so may lead to an accident,  
resulting in death or serious injury.
●Vehicle is driven on a road surface 
which is slippery due to rainy  weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-ered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane or restricted lane due to con- 
struction work.
●Vehicle is driven in a construction 
zone.
●A spare tire, tire chains, etc., are 
equipped.
●When the tires have been exces-
sively worn, or when the tire infla- tion pressure is low.
●When your vehicle is towing a trailer or during emergency towing.
■Preventing LTA system malfunc-tions and operations performed by mistake
●Do not modify the headlights or place stickers, etc., on the surface of the lights.
●Do not modify the suspension, etc. If the suspension, etc., needs to be  
replaced, contact any authorized  Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not install or place anything on the hood or grille. Also, do not  
install a grille guard (bull bars, kan- garoo bar, etc.).
●If your windshield needs repairs, contact any authorized Toyota retailer or Toyota authorized  
repairer, or any reliable repairer.
■Conditions in which functions 
may not operate properly 
In the following situations, the func- tions may not operate properly and  
the vehicle may depart from its lane.  Drive safely by always paying careful attention to your surroundings and  
operate the steering wheel to correct  the path of the vehicle without relying solely on the functions.
●When the follow-up cruising dis-play is displayed ( P.248) and the  
preceding vehicle changes lanes.  (Your vehicle may follow the pre-ceding vehicle and also change  
lanes.)

■Lane departure alert function 
When the system determines that  
the vehicle might depart from its  
lane*, a warning is displayed on the  
multi-information display, and either  
a warning buzzer will sound or the  
steering wheel will vibrate to alert  
the driver.
When the warning buzzer sounds or  
the steering wheel vibrates, check the 
area around your vehicle and carefully 
operate the steering wheel to move the 
vehicle back to the center of the lane. 
Vehicle with BSM: When the system  
determines that the vehicle might 
depart from its lane and that the possi-
bility of a collision with an overtaking 
vehicle in the adjacent lane is high, the 
lane departure alert will operate even if 
the turn signals are operating.
*: May recognize the boundaries 
between the asphalt and the side of 
the road, such as grass, soil, or the 
curb, to be road lanes.
