Driving mode

P.390

To drive using temporary shift range
selection, operate the “-” or “+” paddle
shift switch.
When the “-” paddle shift switch is
operated, the shift range switches to a
range that enables engine braking
force that is suitable to driving condi-
tions. When the “+” paddle shift switch
is operated, the shift range switches to
a range that is one range higher than
the current range.
Changing the shift range allows
restriction of the highest gear, prevent-
ing unnecessary upshifting and
enabling the level of engine braking
force to be selected.

WARNING

■

For the shift lever

●

Do not remove the shift lever knob or

use anything but a genuine Lexus shift

lever knob. Also, do not hang anything

on the shift lever.

Doing so could prevent the shift lever

from returning to position, causing

unexpected accidents to occur when

the vehicle is in motion.

●

In order to prevent the shift position

from accidentally being changed, do

not touch the shift lever when not using

them.

■

P position switch

●

Do not press the P position switch

while the vehicle is moving.

If the P position switch is pressed when

driving at very low speeds (for example,

directly before stopping the vehicle), the

vehicle may stop suddenly when the shift

position switches to P, which could lead

to an accident.

●

In order to prevent the shift position

from accidentally being changed, do

not touch the P position switch when

not using them.

NOTICE

■

When exiting the vehicle (driver’s

seat only)

Check that the shift position indicator

shows P and that the parking brake indi-

cator is illuminated before opening the

door and exiting the vehicle.

The selected shift range, from D1 to D6,
will be displayed on the meter.
To return to normal D position driving, the
“+” paddle shift switch must be held down
for a period of time.

■

Shift ranges and their functions

A lower shift range will provide greater
engine braking forces than a higher shift
range.

■

Automatic deactivation of shift range

selection in the D position

Shift range selection in the D position will

be deactivated in the following situations:

●

When the vehicle comes to a stop

●

If the accelerator pedal is depressed for

more than a certain period of time

●

When the shift position is shifted to a

position other than D.

Downshifting restriction warning

buzzer

To help ensure safety and driving perfor-

mance, downshifting operation may some-

times be restricted. In some circumstances,

downshifting may not be possible even

when the paddle shift switch is operated. (A

buzzer will sound twice.)

To enter M mode, shift the shift position
to M. Gears can be selected by oper-
ating the paddle shift switches, allowing
you to drive in the gear of your choos-
ing.

Upshifting

Downshifting

The gear changes once every time the
paddle shift switch is operated.
The selected gear, from M1 to M6, will be
fixed and displayed on the meter.

When in the M position, the gear will
not change unless the paddle shift
switches are operated. Also, the gear
will not shift when the vehicle speed is
low, even if an upshift operation is per-
formed.
However, even when in the M position,
the gears will be automatically
changed in the following situations:

: To improve fuel efficiency and reduce

noise, set the shift position in D for nor-
mal driving. You can choose gear range
suitable for your driving situation by
operating the paddle shift switches.

: By selecting shift ranges using S mode,

you can control accelerating force and
engine braking force.

When driving with the dynamic radar

cruise control activated

Even when performing the following

actions with the intent of enabling engine

braking, engine braking will not be acti-

WARNING

■

When the vehicle is on a steep incline

Take care when using the brake hold sys-

tem on a steep incline, exercise caution.

The brake hold function may not hold

brakes in such situations.

Also, the system may not activate

depending on the angle of the slope.

■

When stopped on a slippery road

The system cannot stop the vehicle when

the gripping ability of the tires has been

exceeded. Do not use the system when

stopped on a slippery road.

NOTICE

■

When parking the vehicle

The brake hold system is not designed

for use when parking the vehicle for a

long period of time. Turning the power

switch off while the system is holding the

brake may release the brake, which

would cause the vehicle to move. When

operating the power switch, depress the

brake pedal, shift the shift position to P

and set the parking brake.

ASC (Active Sound Control)
(RX500h)

The ASC system is designed to
allow the driver to feel the state of
driving, such as accelerating and
decelerating, more strongly. The

To make your vehicle more visible to

other drivers during daytime driving, the

daytime running lights turn on automati-

Compared to turning on the headlights,

the daytime running light system offers

greater durability and consumes less

electricity, so it can help improve fuel

economy.

Headlight control sensor

The sensor may not function properly if an

object is placed on the sensor, or anything

The following may change the speed at

which the shaded areas change or the

timing at which the headlights change to

the low beams:

• The brightness of lights of vehicles ahead

• The movement and direction of vehicles

ahead

• The distance between the vehicle and a

vehicle ahead
