STARTING AND DRIVING
365 In the power mode, the “ECT PWR” light in the instrument
cluster is on and the most suitable shift pattern is selected
depending on the driver’s operation of accelerator and brake
pedal and on the vehicle condition. See “Automatic shifting
point change control” on page 356.
To return to the normal mode, push the driving pattern selector
switch lightly on the “SNOW” side.
Snow mode: For slippery road surfaces such as in snow. In
this mode, the spinning of the rear wheels is controlled
appropriately.
When you push the driving pattern selector switch on the
“SNOW” side, the snow mode is turned on and the ”ECT
SNOW” light in the instrument cluster comes on.
To return to the normal mode, push the driving pattern selector
switch on the “SNOW” side again.
When you turn the engine switch off in the snow mode, the
electronic throttle control system automatically changes to the
normal mode.
INTUITIVE PARKING ASSIST
G31049
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 distance to an obstacle by displaying
information on the multi−information display and the
screen, and with beeping sounds.

1
Dual sensors
There are four of these steering guidance sensors installed in
the front bumper.
Steering guidance means that when an obstacle is inspected,
not only is the distance estimated, this function judges whether
collision with the obstacle within detection range is avoidable
if the vehicle is steered in a certain direction, and informs the
driver. There will be no warning if it judges that there is no
possibility of collision with the obstacle within detection range.
(See page 369.)
2
Rear corner sensors
There is one of these installed on each corner of the rear
bumper, they inspect obstacles and will sound a warning
depending on the distance to the obstacle. (See page 373.)
3
Back sensors
There are two of these installed near the center of the rear
bumper, they inspect obstacles and will sound a warning
depending on the distance to the obstacle. (See page 374.)
G31050
To use the intuitive parking assist, push the main switch
in the switch box with the engine switch in “IG−ON” mode.
Pushing the main switch again will turn the intuitive
parking assist off.
When you push the main switch, the indicator light in the
instrument cluster comes on and a beep sounds for one
second, indicating that the intuitive parking assist is turned on.
The intuitive parking assist will remain on even after turning the
engine switch to “OFF” and then to “IG−ON” mode with the
main switch on. However, a beep does not sound at this time.
If an error is detected in the intuitive parking assist while
self−checking, beeps sound and a warning appears in the
multi−information display and on the screen. For details, see
“Intuitive parking assist failure warning” on page 378.

When an obstacle is detected, the indicator bars will come
on or flash, accompanied by beeping. How many bars are
lit or flashing depends on the distance to the obstacle.
When the obstacle is not detected any longer, beeps will stop
sounding and the multi−information display and the screen will
return to the previous display.
The volume of the beeps and the display on the screen can be
changed. See “Setting the intuitive parking assist” on page
385.

(A) Collision will be unavoidable: Collision with the
detected obstacle cannot be avoided even by changing the
steering.
(B) Collision will be avoided by changing the steering:
Collision with the obstacle can be avoided by changing the
steering.
(C) Collision will be avoided with the present steering
angle: Even if you continue moving at the present steering
angle, the distance to the obstacle within sensor detection
range will not be less than about 25 cm (0.8 ft.).
The dual sensors detect an obstacle in front of the vehicle
or at an angle to the front of the vehicle, and estimate the
distance to the obstacle and also the steering angle
required. They will evaluate which of the above 3
conditions is applicable.The selector lever must be in any position other than “P” or “R”
for these sensors to operate, however the obstacle at an angle
to the front of the vehicle will also be detected while the selector
lever is in “R”.
CAUTION
With long obstacles such as walls, the decision of the
sensor may change as the obstacle gets closer; from
certain avoidance to avoidance if steering is changed;
from certain avoidance to unavoidable collision; and
there are also times when the decision will be changed
from avoidance if steering is changed, to certain
collision. When you move your vehicle, be sure to
confirm a safe distance around your vehicle with your
eyes and drive slowly, or an accident or injury may
result.
The steering guidance may not operate properly in the
following conditions:
Tires other than those of Lexus genuine size are
installed.
The steering sensor information cannot be received
properly. (See “Intuitive parking assist failure warning”
on page 378.)
