2018 LEXUS LS500H ESP

351-1. For safe use
LS500h_OM_OM50F42U_(U) 1
For safety and security WARNING
• If your steering wheel is adjustable, tilt
it downward. This points the airbag
toward your chest instead of your head
and neck.
The seat should be adjusted as recom-
mended by NHTSA above, while still
maintaining control of the foot pedals,
steering wheel, and your view of the
instrument panel controls. ●
If the seat belt extender has been con-
nected to the front seat belt buckles
but the seat belt extender has not also
been fastened to the latch plate of the
seat belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front air-
bags may not activate correctly in a
collision, resulting in death or serious
injury in the event of a collision. Be
sure to wear the seat belt with the seat
belt extender.
●
The SRS front passenger airbag also
deploys with considerable force, and
can cause death or serious injury
especially if the front passenger is very
close to the airbag. The front passen-
ger seat should be as far from the air-
bag as possible with the seatback
adjusted, so the front passenger sits
upright. ●
Improperly seated and/or restrained
infants and children can be killed or
seriously injured by a deploying airbag.
An infant or child who is too small to
use a seat belt should be properly
secured using a child restraint system.
Lexus strongly recommends that all
infants and children be placed in the
rear seats of the vehicle and properly
restrained. The rear seats are safer for
infants and children than the front pas-
senger seat. ( → P.45)●
Do not sit on the edge of the seat or
lean against the dashboard.
●
Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
●
Do not allow the front seat occupants
to hold items on their knees.

Running out of fuel
When the vehicle has run out of fuel and the
hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to
make the low fuel level warning light
( → P.430) go off. If there is only a small
amount of fuel, the hybrid system may not be able to start. (The standard amount of
fuel is about 3.4 gal. [13 L, 2.8 Imp. gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.) ■
Electromagnetic waves ●
High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
shielding, and therefore emit approxi-
mately the same amount of electromag-
netic waves as conventional gasoline
powered vehicles or home electronic
appliances.
●
Your vehicle may cause sound interfer-
ence in some third party-produced radio
parts.
■
Hybrid battery (traction battery)
The hybrid battery (traction battery) has a
limited service life. The lifespan of the
hybrid battery (traction battery) can Hybrid system precautions Take care when handling the hybrid system, as it is a high voltage system (about
650 V at maximum) as well as contains parts that become extremely hot when
the hybrid system is operating. Obey th e warning labels attached to the vehi-
cle.

■
Engine speed
On hybrid vehicles, engine speed is pre-
cisely controlled in order to help improve
fuel efficiency and reduce exhaust emis-
sions etc.
There are times when the engine speed that
is displayed may differ even when vehicle operation and driving conditions are the
same. ■
Hybrid System Indicator is displayed
when
The Hybrid System Indicator is displayed in
the following situations: ●
The shift position is in D or M. ●
The driving mode is other than sport
mode.
However, the Hybrid System Indicator will
not be displayed when the analog and digi-
tal speedometers are both enabled on
of the multi-information display. ( → P.90)■
Outside temperature display ●
In the following situations, the correct
outside temperature may not be dis-
played, or the display may take longer
than normal to change:
• When stopped, or driving at low speeds
(less than 12 mph [20 km/h])
• When the outside temperature has
changed suddenly (at the entrance/exit of
a garage, tunnel, etc.) ●
When “--” or “E” is displayed, the system
may be malfunctioning. Take your vehicle

Display items
 Odometer Displays the total distance the vehicle has
been driven.
 Trip meter A/trip meter B Displays the distance the vehicle has been
driven since the meter was last reset. Trip
meters A and B can be used to record and
display different distances independently.

The information display at low tem-
peratures
Allow the interior of the vehicle to warm
up before using the liquid crystal infor-
mation display. At extremely low tem-
peratures, the information display
monitor may respond slowly, and display
changes may be delayed.
For example, there is a lag between the
driver’s shifting and the new gear number
appearing on the display. This lag could
cause the driver to downshift again,
causing rapid and excessive engine brak-
ing and possibly an accident resulting in
death or injury.
NOTICE■
To prevent damage to the engine and
its components ●
Do not let the indicator needle of the
tachometer enter the red zone, which
indicates the maximum engine speed. ●
The engine may be overheating if the
engine coolant temperature gauge is
in the red zone (H). In this case, imme-
diately stop the vehicle in a safe place,
and check the engine after it has
cooled completely. ( → P.453)

WARNING■
Cautions during setting up the dis-
play
As the hybrid system needs to be operat-
ing during setting up the display, ensure
that the vehicle is parked in a place with
adequate ventilation. In a closed area
such as a garage, exhaust gases includ-
ing harmful carbon monoxide (CO) may
collect and enter the vehicle. This may
lead to death or a serious health hazard.
NOTICE■
During setting up the display
To prevent 12-volt battery discharge,
ensure that the hybrid system is operat-
ing while setting up the display features.
