■ When changing the tires
Depending on the tires used, sufficient performance may not be maintain-
able.
■ If the LDA indicator comes on in yellow
It may indicate a malfunction in the system. Contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■ Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the
vehicle automatically, nor does it reduce the amount of care you need to
take. As such, the driver must always assume full responsibility for under-
standing his/her surroundings, for operati ng 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.
● Do not modify the suspension. If your suspension needs repairs, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
● Do not install or place anything on the hood or the grille. Also, do not install
a grille guard (bull bars, kangaroo bar etc.).
