CAUTION

■

Limitations of the pre-collision system

Do not rely on the pre-collision system. Always drive safely, taking care to observe

your surroundings and checking for any obstacles or other road hazards.

■

When the sensor may not be correctly detecting the vehicle ahead

Apply the brakes as necessary in any of the following situations:

●

When water or snow thrown up by the surrounding vehicles hinders the function-

ing of the sensor

●

When your vehicle is pointing upwards (caused by a heavy load in the luggage

compartment etc.)

●

Vehicles that cut in suddenly

●

Vehicles with small rear ends (trailers with no load on board etc.)

●

Motorcycles traveling in the same lane

■

Handling the radar sensor

Observe the following to ensure the pre-collision system can function effectively:

●

Keep the sensor and front grille clean at all times.

Clean the sensor and front grille with a soft cloth so you do not mark or damage

them.

●

Do not subject the sensor or surrounding area to a strong impact.

If the sensor moves even slightly off position, the system may malfunction. If the

sensor or surrounding area is subject to a strong impact, always have the area

inspected and adjusted by your Lexus dealer.

●

Do not disassemble the sensor.

●

Do not attach accessories or stickers to the sensor, grille or surrounding area.

●

Do not modify or paint the sensor and grille cover.
