2007 Lexus ES350 warning

256INTUITIVE PARKING ASSIST
ES350_Navi_U (L/O 0603)
The Intuitive parking assist 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 dis-
tance to an obstacle by displaying in-
formation on the multi-information dis-
play 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
 Ð Front corner sensorsº on page 258.)
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
 Ð Rear corner sensorsº on page 259.)
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
 Ð Back sensorsº on page 260.)
To use the Intuitive parking assist, with
the engine switch in IG-ONº mode,
push the Intuitive parking assist but-
ton. Pushing the Intuitive parking as-
sist button again will turn the Intuitive
parking assist off.
When ON, an indicator on the switch
comes on to inform the driver that the func-
tion is operational.
The Intuitive parking assist will remain on
even after turning the engine switch to
OFFº and then to IG-ONº mode with the
main switch on. However, a beep does not
sound at this time.
If an error is detected in the Intuitive park-
ing assist while self-checking, beeps
sound and a warning appears in the multi-
information display and on the screen. For
details, see  Ð Intuitive parking assist fail-
ure warningº on page 263.

3Less than about 0.8 ft. (25 cm)
The front corner sensor only operates
when the vehicle speed is less than
about 6 mph (10 km/h). It checks the
approximate distance to obstacles at
an angle to the front of the vehicle, and
sounds a warning depending on the
distance. This sensor does not operate
if the transmission is in Pº position.Multi-information display:
The indicator bars come on depending on
the distance to the obstacle and flash
when the distance between the vehicle
and the obstacle is less than about 0.8 ft.
(25 cm).
Touch screen:
When an obstacle is detected, indicator
bars illuminate in yellow. The number of
the indicator bars reduces as the vehicle
gets closer to the obstacle, and turn red
when the distance between the vehicle
and obstacle is less than 0.8 ft. (25 cm).
Beeps:
As distance to the obstacle gets closer, the
interval of the intermittent sound gets
shorter, and then finally changes to a con-
tinuous sound when the distance between
the vehicle and the obstacle is less than
about 0.8 ft. (25 cm).
CAUTION
When you move your vehicle, be sure
to visually confirm a safe distance
around your vehicle and drive slowly,
or an accident or injury may result.

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 indica-
tor bars. And beeps are as follows:
1Obstacles detected on the front
and rear of the vehicle are not in
areas where continuous beeping
should sound:
The warning for the obstacle closer to the
vehicle will be issued. The above illustra-
tion 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.
2The 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 ob-
stacle is high as shown, the Intuitive park-
ing assist warns the driver by continuous
beeping (repeating 7 intermittent beeps
and one longer beep as one cycle).
3Both 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 ob-
stacles is very high as shown, the Intuitive
parking assist warns the driver by continu-
ous beeping (repeating 3 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 the air conditioning. To
avoid an accident or injury, drive
slowly using the brakes while visual-
ly confirming a safe distance around
your vehicle.
Ð Numerous obstacles are
detected on the front and rea
r
of the vehicle simultaneously

may be affected.)
When a radio antenna or fender pole is
mounted on your vehicle.
If towing eyelet is installed on your ve-
hicle.
When you are driving towards a tall
curb stone or curb stone having right
angle.
The detection range for an object such
as a traffic sign may be shortened.
An object just under the bumper cannot
be detected. Although an object lower
than the location of sensors is once de-
tected, the detection might be stopped
when your vehicle gets closer to the
object.
When an obstacle is very close to the
sensors.
The Intuitive parking assist may not de-
tect 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 project-
ed
Shorter objectsIf an error is detected when the Intuitive
parking assist is turned on, the vehicle
symbol comes on or flashes with beep-
ing sounds.
However, the sensors functioning properly
continue their obstacle detection.

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 ve-
hicle symbol and the indicator bars cor-
responding to the faulty sensors flash
for about 7 seconds and 2 beeps sound

After about 7 seconds, the sensor indi-
cator bars will cease flashing, however
will stay lit until the affected sensor is
cleaned. Furthermore, the vehicle sym-
bol will continue to flash until the af-
fected 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 In-
tuitive parking assist may be malfunction-
ing. Have it checked by your Lexus dealer.(b) When the sensor is malfunctioning
