4-3. Operating the lights and wipers
• 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.
• When driving in inclement weather (heavy rain, snow, fog, sandstorms, etc.)
• When the windshield is obscured by
fog, mist, ice, dirt, etc.
• When the windshield is cracked or damaged• When the front camera is deformed or
dirty • When the temperature of the front camera is extremely high
• When the surrounding brightness level is equal to that of headlights, tail lights or fog lights
• When headlights or tail lights of vehi- cles ahead are turned off, dirty, chang-ing color, or not aimed properly
• When the vehicle is hit by water, snow, dust, etc., from a preceding vehicle
• When driving through an area of inter- mittently changing brightness and darkness
• When frequently and repeatedly driv- ing ascending/descending roads, or roads with rough, bumpy or uneven
surfaces (such as stone-paved roads, gravel roads, etc.)• When frequently and repeatedly tak-
ing curves or driving on a winding road• When there is a highly reflective
object ahead of the vehicle, such as a sign or mirror• When the back of a preceding vehicle
is highly reflective, such as a con- tainer on a truck• When the vehicle’s headlights are
damaged or dirty, or are not aimed properly• When the vehicle is listing or titling
due to a flat tire, a trailer being towed, etc.• When the headlights are changed
between the high beams and low beams repeatedly in an abnormal manner
• When the driver believes that the high beams may be flashing or dazzling pedestrians or other drivers

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.234) and the
preceding vehicle changes lanes. (Your vehicle may follow the pre-ceding vehicle and also change
lanes.)

4-5. Using the driving support systems
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, d etermines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may become
shorter.

*: If equipped
The RSA system recognizes spe-
cific road signs using the front cam-
era and/or 7-inch/8-inch display
navigation system (when speed
limit information is available) to pro-
vide information to the driver via the
display.
If the system judges that the vehicle
is being driven over the speed limit,
performing prohibited actions, etc.
according to the recognized road
signs, it notifies the driver through a
visual notification and notification
buzzer.
WARNING
■To avoid operating the speed lim- iter by mistake
