Toyota RAV4 Owners Manual: Lda (lane departure alert)

Summary of function

While driving on a road that has lane markers, this system recognizes the lane markers using a camera as a sensor to alert the driver when the vehicle deviates from its lane.

If the system judges that the vehicle may deviate from its lane, it alerts the driver using beeping and indications on the instrument cluster.

Depending on the audio system sound level or air conditioning fan noise while the audio system or air conditioning system is in use, it may be difficult to hear the warning sound.

The lda system may not be available and the lda indicator comes on in yellow for a while after driving has started.

When the temperature in the cabin decreases and the temperature around the camera sensor („_p. 245) Becomes suitable for its operation, the functions will begin to operate.

If there are lane markers on only one side of the vehicles

The lane departure warning will not operate for the side on which lane markers could not be recognized.

Conditions in which the function may not operate correctly

In the following conditions, the camera sensor may be unable to recognize lane markers causing the lane departure warning function to operate incorrectly.

However, this does not indicate a malfunction.

When changing the tires

Depending on the tires used, sufficient performance may not be maintainable.

Warning indicators for lda system

Warning indicators are used to indicate a system malfunction or to inform the driver of the need for caution while driving.


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 understanding his/her surroundings, for operating 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.

Situations unsuitable for lda system

Do not use lda system in any of the following situations.

Otherwise, the system may not function correctly and could result in an accident.
