2006 Lexus GS300 warning

STARTING AND DRIVING
374The rear corner sensor only operates when the
transmission is in “R”, it checks the approximate distance
to obstacles at an angle to the rear of the vehicle, and
sounds a warning depending on the distance.
1
Multi−information display:
The indicator bars will come on depending on the
distance to the obstacle and will flash when the distance
between the vehicle and the obstacle is less than about
25 cm (0.8 ft.).
2
Screen:
The indicator bars will come on in yellow depending on
the distance to the obstacle. When the distance between
the vehicle and the obstacle is less than about 25 cm (0.8
ft.), the yellow indicator bars will turn red.
Beeps:
As distance to the obstacle gets closer, the interval of the
intermittent sound gets shorter, and then finally to a continuous
sound when the distance between the vehicle and the obstacle
is less than about 25 cm (0.8 ft.).
CAUTION
When backing up, be sure to confirm a safe distance
around your vehicle with your eyes to avoid an accident.

375 The back sensor only operates when the transmission is
in “R”, it checks the approximate distance to obstacles
close to the rear of the vehicle, and sounds a warning
depending on the distance.

Numerous obstacles are detected on the front
and rear of the vehicle simultaneously
G31060
When obstacles are detected on the front and rear of the
vehicle at the same time; the multi−information display
and screen illuminate their relevant indicator bars. And
beeps are as follows:
1
Obstacles detected on the front and rear of the
vehicle are not in areas where continuous beeping
should sound:

STARTING AND DRIVING
376The warning for the obstacle closer to the vehicle will be
issued. The above illustration indicates the obstacle detected
by the back sensors is closer to the vehicle. So, the warning for
the obstacle detected by the back sensors will be given.
2
The obstacle detected on the front or rear of the
vehicle is in an area where continuous beeping
should sound:
If the possibility of collision with the obstacle is high as shown,
the system warns the driver by continuous beeping (repeating
6 intermittent beeps and one longer beep as one cycle).
3
Both obstacles detected on the front and rear of the
vehicle are in areas where continuous beeping
should sound:
If the possibility of collision with the obstacles is very high as
shown, the system warns the driver by continuous beeping
(repeating 2 quick beeps and one longer beep as one cycle).
CAUTION
It might be difficult to hear beeps due to the volume of
audio or air flow noise of air conditioning. To avoid an
accident or injury, drive slowly using the brakes while
confirming a safe distance around your vehicle with
your eyes.
Detection range of sensors*
G31061

1
About 3 m (10 ft.) 2
About 1 m (3 ft.)
3
About 1m 50 cm (5 ft.) 4
About 50 cm (1.5 ft.)
The sensor detection range is limited around the bumper.
Be sure to confirm a safe distance around your vehicle
and drive slowly.

STARTING AND DRIVING
378The intuitive parking assist may not detect the following:
Thin objects such as wire or rope
Sound wave absorbing objects such as cotton or snow
Objects with a sharp edge
Tall objects with the upper part projected
Shorter objects
Intuitive parking assist failure warning
If an error is detected when the intuitive parking assist is
turned on, the vehicle symbol comes on or flashes with
beeping sounds.
At this time steering guidance is temporarily stopped.
However, the sensors functioning properly continue their
obstacle detection. For details, see “When the detection range
of the sensors is shorter” on page 381.
The intuitive parking assist failure warning display is not given
in either of the following operations:
Changing to another screen
Turning off the main switch for the intuitive parking assist

STARTING AND DRIVING
379 When snowflakes or mud gets on the sensors

Multi−information display 2
Screen
If foreign matter gets on the sensors and the intuitive
parking assist cannot detect the object properly, the
above message appears. At this time, the vehicle symbol
and the indicator bars corresponding to the faulty
sensors flash for about 7 seconds and 2 beeps sound 5
times.
After about 7 seconds, the sensor indicator bars will
cease flashing, however will stay lit until the affected
sensor is cleaned. Furthermore, the vehicle symbol will
continue to flash until the affected sensor is cleaned.
The above illustration shows the sensor on the left front of the
vehicle malfunctioning.
If the failure warning does not go off even after the foreign
matter is removed, the intuitive parking assist may be
malfunctioning. Have it checked by your Lexus dealer.When the sensor is malfunctioning

Screen
If the sensor cable is broken and the intuitive parking
assist cannot detect the object properly, the above
message appears. At this time, the indicator bars
corresponding to the faulty sensor flash for about 7
seconds and 2 beeps sound 5 times.
The indicator bars continue lighting after flashing.
The above illustration shows the sensor on the right rear of the
vehicle malfunctioning.
If this message appears, have the sensor checked by your
Lexus dealer.

STARTING AND DRIVING
380When the steering sensor is malfunctioning
G31064
If the steering sensor cable is broken and signals cannot
be received, the vehicle symbol comes on and the
steering guide symbol and arrows flash.
If only the steering sensor is malfunctioning, the warning
appears only on the multi−information display.
If this warning appears, have the sensor checked by your
Lexus dealer as soon as possible.When the neutral point of the steering sensor is unknown
G31065
If the memorized neutral point of the steering is erased by
replacing the battery, the vehicle symbol, steering guide
symbol and arrows come on.
If only the neutral point of the steering sensor is unknown, the
warning appears only on the multi−information display.
If this warning appears, calibrate the neutral point of the
steering using either of the following:
Turn the steering wheel either way fully and then in the
opposite direction fully and slowly, with the vehicle stopped.
Drive on roads (with as few curves as possible and without
backing up) for more than about 5 minutes.
If this warning goes out, the calibration of the steering neutral
point is completed. If the warning still remains on, have the
sensor checked by your Lexus dealer as soon as possible.

STARTING AND DRIVING
381 As the intuitive parking assist might be malfunctioning in
the following cases, have it checked by your Lexus dealer.
The indicator in the instrument cluster does not come on
and a beep does not sound even when the intuitive parking
assist main switch is turned on.
The warning comes on despite no obstacle around the
vehicle.
When the detection range of the sensors is
shorter
In the following cases, the sensors will detect an obstacle
about 50 cm (1.5 ft.) from either front corner of the vehicle
and the steering guidance will be stopped. Accordingly,
the tire orientation symbol on the screen does not appear.
And only the warning according to the distance up to the
obstacle is given.
a. Any one of the sensors is malfunctioning.
b. Any one of the steering sensors is malfunctioning.
c. The steering sensor signal cannot be received properly.
d. The correct vehicle information cannot be given due to
extremely low battery voltage.
e. Proper steering detection (going straight) cannot be
detected
In case of a., when the intuitive parking assist returns to
normal, the steering guidance also comes back automatically.
In case of b. through e., the steering guidance also comes back
automatically after the neutral point of the steering sensor
calibration is completed.
