■
For safe driving
Observe the following precautions.
Failure to do so may result in death or
serious injury. A
B
C
D ●
Do not adjust the position of the
driver’s seat while driving.
Doing so could cause the driver to lose
control of the vehicle. ●
Do not place a cushion between the
driver or passenger and the seatback.
A cushion may prevent correct pos-
ture from being achieved, and reduce
the effectiveness of the seat belt and
head restraint. ●
Do not place anything under the front
seats.
Objects placed under the front seats
may become jammed in the seat
tracks and stop the seat from locking in
place. This may lead to an accident
and the adjustment mechanism may
also be damaged. ●
Always observe the legal speed limit
when driving on public roads. ●
When driving over long distances, take
regular breaks before you start to feel
tired.
Also, if you feel tired or sleepy while
driving, do not force yourself to con-
tinue driving and take a break immedi-
ately.
Correct use of the seat belts

LS500h_OM_OM50F42U_(U) 1-3.Hybrid system
■
System components
The illustration is an example for explanation and may differ from the actual item.
Gasoline engine
Electric motor (traction motor) ■
When stopped/during start off
The gasoline engine stops *
when the
vehicle is stopped. During start off, the
electric motor (traction motor) drives
the vehicle. At slow speeds or when
traveling down a gentle slope, the
engine is stopped *
and the electric
motor (traction motor) is used.
When the shift position is in N, the hybrid battery (traction battery) is not
being charged. *
: When the hybrid battery (traction bat-
tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop.
■
During normal driving
The gasoline engine is predominantly
used. The electric motor (traction
motor) charges the hybrid battery Hybrid system features Your vehicle is a hybrid vehicle. It has characteristics different from conven-
tional vehicles. Be sure you are closely familiar with the characteristics of your
vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and an electric motor
(traction motor) according to driving conditions, improving fuel efficiency and
reducing exhaust emissions.

591-3. Hybrid system
LS500h_OM_OM50F42U_(U) 1
For safety and security (traction battery) as necessary. ■
When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of the
hybrid battery (traction battery) is
added to that of the gasoline engine via
the electric motor (traction motor). ■
When braking (regenerative brak-
ing)
The wheels operate the electric motor
(traction motor) as a power generator,
and the hybrid battery (traction bat-
tery) is charged. ■
Regenerative braking
In the following situations, kinetic energy is
converted to electric energy and decelera-
tion force can be obta ined in conjunction
with the recharging of the hybrid battery
(traction battery). ●
The accelerator pedal is released while
driving with the shift position in D or M.●
The brake pedal is depressed while driv-
ing with the shift position in D or M.■
EV indicator
The EV indicator comes on when the vehi-
cle is driven using only the electric motor
(traction motor) or th e gasoline engine is
stopped.
■
Conditions in which the gasoline engine
may not stop
The gasoline engine starts and stops auto-
matically. However, it may not stop auto-
matically in the following conditions:
●
During gasoline engine warm-up ●
During hybrid battery (traction battery)
charging ●
When the temperature of the hybrid bat-
tery (traction battery) is high or low ●
When the heater is switched on ●
When the shift position is in M
Depending on the circumstances, the gaso-
line engine may also not stop automatically
in other situations. ■
Charging the hybrid battery (traction
battery)
As the gasoline engine charges the hybrid
battery (traction battery), the battery does
not need to be charged from an outside
source. However, if the vehicle is left parked
for a long time the hybrid battery (traction
battery) will slowly discharge. For this rea-
son, be sure to drive the vehicle at least
once every few months for at least 30 min-
utes or 10 miles (16 km ). If the hybrid bat-
tery (traction battery) becomes fully
discharged and you are unable to contact
your Lexus dealer. ■
Charging the 12-volt battery
→ P.447 ■
After the 12-volt battery has discharged
or when the terminal has been removed
and installed during exchange, etc.
The gasoline engine may not stop even if
the vehicle is being driven by the hybrid bat-
tery (traction battery). If this continues for a
few days, contact your Lexus dealer. ■
Sounds and vibrations specific to a
hybrid vehicle
There may be no engine sound or vibration
even though the vehicle is able to move with
the “READY” indicator is illuminated. For
safety, apply the parking brake and make
sure to shift the shift position to P when
parked.
The following sounds or vibrations may
occur when the hybrid system is operating
and are not a malfunction:
●

accelerating sharply.●
Sounds may be heard due to regenera-
tive braking when the brake pedal is
depressed or as the accelerator pedal is
released.●
Vibration may be felt or sounds may be
heard when the gasoline engine starts or
stops.●
