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.)
