standing his/her surroundings, for operat ing the steering wheel to correct
the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■ To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
NOTICE
■ To prevent damage to or incorrect operation of the LDA system
● Do not modify the headlights or attach stickers to the surface of the lights.

any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.

a grille guard (bull bars, kangaroo bar etc.).
