1614-1. Before driving
LS500h_OM_OM50F42U_(U) 4
Driving WARNING●
Do not shift the shift position to P while
the vehicle is moving.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.●
Do not shift the shift position to R while
the vehicle is moving forward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.●
Do not shift the shift position to a driv-
ing position while the vehicle is moving
backward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.●
Changing the shift position to N while
the vehicle is moving will disengage
the hybrid system. Engine braking is
not available with the hybrid system
disengaged.●
Be careful not to change the shift posi-
tion with the accelerator pedal
depressed. Changing the shift posi-
tion to any positions other than P or N
may lead to unexpected rapid acceler-
ation of the vehicle that may cause an
accident and result in death or serious
injury.
After changing the shift position, make
sure to confirm the current shift posi-
tion displayed on the shift position indi-
cator inside the meter.
■
Brake pad wear
If any of the following situations occurs,
have the brake pads visually checked and
replaced by your Lexus dealer as soon as
possible.
●
If the thickness of the brake pads
exceeds the brake pad wear limit when
visually checking all four brake pads
(for the brake pad wear limit, refer to
P.465) ●
If a warning message is displayed on
the multi-information display (only the
right-side pads can be detected)
Rotor damage may result if the pads are
not replaced when needed.
F SPORT models: Moderate levels of the
brake pad and disc wear allow enhanced
braking power. As a result, the discs may
wear more quickly than conventional
brake discs. Therefore, when replacing
the brake pads, Lexus recommends that
you also have the thickness of the discs
measured.
It is dangerous to drive the vehicle when
the wear limits of the brake pads and/or
those of the brake discs are exceeded. ■
When the vehicle is stopped ●
Do not depress the accelerator pedal
unnecessarily.
If the shift position is any position other
than P or N, the vehicle may acceler-
ate suddenly and unexpectedly, caus-
ing an accident. ●
In order to prevent accidents due to
the vehicle rolling away, always keep
depressing the brake pedal while
stopped with the “READY” indicator is
illuminated, and apply the parking
brake as necessary.
●
If the vehicle is stopped on an incline,
in order to prevent accidents caused
by the vehicle rolling forward or back-
ward, always depress the brake pedal
and securely apply the parking brake
as needed.
●
Avoid revving or racing the engine.
Running the engine at high speed
while the vehicle is stopped may cause
the exhaust system to overheat, which
could result in a fire if combustible
material is nearby.

1774-2. Driving procedures
LS500h_OM_OM50F42U_(U) 4
Driving ■
Shifting the shift position from P to
other positions
 While depressing the brake pedal
firmly, operate the shift lever. If the
shift lever is operated without
depressing the brake pedal, the
buzzer will sound and the shifting
operation will be disabled.
 When selecting the shift position,
make sure that the shift position has
been changed to the desired posi-
tion by checking the shift position
indicator provided on the instru-
ment cluster.
 The shift position cannot be
changed from P to M directly. ■
Automatic P position selection function
In the following situations, the shift position
is automatically changed to P. ●
When pressing the power switch with the
vehicle stopped while the power switch is
in ON mode and the shift position is in a
position other than P (after the shift posi-
tion has changed to P, the power switch
will turn off) *
●
When the vehicle is stopped after the
hybrid system has been stopped in an
emergency while driving●
When voltage of the 12-volt battery
drops while the shift po sition is in a posi-
tion other than P *
: When the power switch is pressed while
driving at extremely slow speeds, such
as immediately before stopping the vehi-
cle, the shift position may automatically
change to P. Make sure that the vehicle
is completely stoppe d before pressing
the power switch.
■
If the shift position cannot be shifted
from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt battery in
this situation. ( → P.447)
■
Driving mode
→ P.298 ■
Snow mode
Snow mode can be se lected to suit the
conditions when driving on slippery
road surfaces, such as on snow.
Turn the snow mode switch backward. The snow mode indicator illuminates.
Turn the snow mode switch backward
again to return to normal mode. WARNING■
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 exam-
ple, directly before stopping the vehi-
cle), 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 or shift
lever when not using them.
NOTICE■
Notes regarding shift lever and P
position switch operation
Avoid repeatedly operating the shift
lever and P position switch in quick suc-
cession.
The system protection function may acti-
vate and it will not be temporarily possi-
ble to shift the shift position other than P.
If this happens, please wait for a while
before attempting to change the shift
position again.

Before using dynamic radar cruise
control with full-speed range
Driving safely is the sole responsibility of
the driver. Do not rely solely on the sys-
tem, and drive safely by always paying
careful attention to your surroundings.
The dynamic radar cruise control with
full-speed range provides driving assis-
tance to reduce the driver’s burden.
However, there are limitations to the
assistance provided.
Set the speed appropriately depending
on the speed limit, traffic flow, road con-
ditions, weather conditions, etc. The
driver is responsible for checking the set
speed.
Even when the system is functioning nor-
mally, the condition of the preceding
vehicle as detected by the system may
differ from the condition observed by the
driver. Therefore, the driver must always
remain alert, assess the danger of each
situation and drive safely. Relying solely
on this system or assuming the system
ensures safety while driving can lead to
an accident, resulting in death or serious
injury. A

Cautions regarding the driving assist
systems
Observe the following precautions, as
there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident
resulting in death or serious injury.●
Assisting the driver to measure follow-
ing distance
The dynamic radar cruise control with
full-speed range is only intended to
help the driver in determining the fol-
lowing distance between the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows careless or inattentive driv-
ing, and it is not a system that can assist
the driver in low-visibility conditions. It
is still necessary for driver to pay close
attention to the vehicle’s surroundings. ●
Assisting the driver to judge proper
following distance
The dynamic radar cruise control with
full-speed range determines whether
the following distance between the
driver’s own vehicle and a designated
vehicle traveling ahead is within a set
range. It is not capable of making any
other type of judgement. Therefore, it
is absolutely necessary for the driver to
remain vigilant and to determine
whether or not there is a possibility of
danger in any given situation.
●
Assisting the driver to operate the
vehicle
The dynamic radar cruise control with
full-speed range does not include
functions which will prevent or avoid
collisions with vehicles ahead of your
vehicle. Therefore, if there is ever any
possibility of danger, the driver must
take immediate and direct control of
the vehicle and act appropriately in
order to ensure the safety of all
involved.
