LEXUS PARKING ASSIST−SENSOR
278
The Lexus parking assist−sensor is a
warning system used when parking the
vehicle at low speed (e.g. into a garage).
It uses an ultrasonic sensor, which
checks the approximate distance to an
obstacle. It will inform you of the
approximate distance to an obstacle by
displaying information on the multi −in-
formation display and the screen, and
with beeping sounds.
1Front corner sensors
There is one of these installed on each cor-
ner of the front bumper, they inspect ob-
stacles and will sound a warning depend-
ing on the distance to the obstacle. (See
“ — Front corner sensors” on page 280.)
2Rear corner sensors
There is one of these installed on each cor-
ner of the rear bumper, they inspect ob-
stacles and will sound a warning depend-
ing on the distance to the obstacle. (See
“ — Rear corner sensors” on page 281.)
3Back sensors
There are two of these installed near the
center of the rear bumper, they inspect ob-
stacles and will sound a warning depend-
ing on the distance to the obstacle. (See
“ — Back sensors” on page 282.)
To use the parking assist −sensor, with
the “ENGINE START STOP” switch in
IGNITION ON mode, push “
”or“”
of the satellite switch to select the park-
ing assist− sensor and then push the
ON/OFF button. Selecting the parking
assist− sensor and pushing the ON/OFF
button of the satellite switch again will
turn the parking assist −sensor off.
When you turn on the parking assist −sen-
sor, the indicator light in the instrument
cluster comes on and a beep sounds for
one second, indicating that the parking as-
sist− sensor is turned on.
The parking assist −sensor will remain on
even after turning the “ENGINE START
STOP” switch to OFF and then to IGNI-
TION ON mode with the main switch on.
However, a beep does not sound at this
time.
If an error is detected in the Lexus parking
assist− sensor while self −checking, beeps
sound and a warning appears in the multi −
information display and on the screen. For
details, see “ — Lexus parking assist −sen-
sor failure warning” on page 285.
