359 “S” mode indicator light
“S” mode allows you to use the shift range positions.
The “S” mode indicator light comes on when the selector
lever is shifted into the “S” position. When the “S” mode
indicator light does not come on even with the selector lever
moved to the “S” position, there may be a problem
somewhere in the system. Have your vehicle
checked/repaired by your Lexus dealer as soon as
possible. In this case, you can drive in the same condition
as in the “D” position.
(c) Using engine braking
G31027
“S” mode position
To use the braking power of the engine, downshift the range in
the “S” mode position as follows:
Shift into the “5” (fifth range) position. The transmission will
downshift to fifth gear and engine braking will be enabled.
If you drive in the “D” position: Shift the selector lever to
the “S” position and “5” (fifth range) will automatically be
selected.
If you drive in the “S” position: Shift the selector lever
down to the “–” position by selecting the “5” (fifth range).

STARTING AND DRIVING
360When the cruise control is being used, even if you downshift
from “D” or “6” (sixth range) to “5” (fifth range), engine
braking will not be enabled because the cruise control is not
cancelled. For vehicle speed reduction, see page 394.
Vehicles with the dynamic radar cruise control —
When the cruise control is being used in the conventional
(fixed speed) cruise control mode or in the
vehicle−to−vehicle distance control mode, even if you
downshift from “D” or “6” (sixth range) to “5” (fifth range),
engine braking will not be enabled because the cruise
control is not cancelled. For vehicle speed reduction, see
pages 416 and 404.

fourth and overdrive gears when climbing a gentle slope, shift
the selector lever to the “4” position. Be sure to shift the
selector lever to the “D” position after climbing the slope.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or the parking brake to hold
the vehicle on an upgrade. Do not attempt to hold the
vehicle using the accelerator pedal, as this can cause
the transmission to overheat.

Snow position
The electronic throttle control system has 3 modes:
normal, power and snow modes.
Normal mode: For ordinary driving, Lexus recommends that
you use this mode to improve fuel economy.
Power mode: For more powerful acceleration and sporty
driving.
Page 27 of 110
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.

Steering guide symbol (See page 371)
The approximate distance to the obstacle is shown with up to
4 bars on the front, front corners and rear of the vehicle and up
to 3 bars on the rear corners of the vehicle.
CAUTION
To avoid an accident or injury, observe the following
instructions, and then drive slowly using the brakes
while confirming a safe distance around your vehicle
with your eyes.
The sensor detection range is limited around the
bumper. Be sure to confirm safety outside sensor
detection with your eyes. For the sensor detection
range, see page 376.
It might take time for the sensors to detect the
obstacle.
Depending on the shape of the obstacle, indicators or
beeps may not warn you properly, and the detection
range may also be shortened.
It might be difficult to hear beeps due to the volume
of audio or air flow noise of air conditioning.
