631-4. Hybrid system
1
For safety and security
*: 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
(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 gasoline engine may also not stop auto-
matically 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 start the
hybrid system, contact your Lexus dealer.
■Charging the 12-volt battery
P.374
■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.

For safety and security
■Alarm-operated door lock
In the following cases, depending on the sit-
uation, the door may automatically lock to
prevent improper entry into the vehicle:
●When a person remaining in the vehicle
unlocks the door and the alarm is acti-
vated.
●While the alarm is activated, a person
remaining in the vehicle unlocks the door.
●When recharging or replacing the 12-volt
battery
NOTICE
■To ensure the system operates cor-
rectly
Do not modify or remove the system. If
modified or removed, the proper opera-
tion of the system cannot be guaranteed.
Theft prevention labels
(U.S.A.)
These labels are attached to the
vehicle to reduce vehicle theft by
facilitating the tracing and recov-
ery of parts from stolen vehicles.
Do not remove under penalty of
law.

●As the electronic ke y always receives
radio waves, the battery will become
depleted even if the electronic key is not
used. The following symptoms indicate
that the electronic key battery may be
depleted. Replace the battery when nec-
essary. ( P.330)
• The smart access system with push-but- ton start or the wireless remote control
does not operate.
• The detection area becomes smaller.
•The LED indicator on the key surface does not turn on.
You can replace the battery by yourself
( P.330). However, as there is a danger
that the electronic key may be damaged, it
is recommended that replacement be car-
ried out by your Lexus dealer.
●To avoid serious deterioration, do not
leave the electronic ke y within 3 ft. (1 m)
of the following electr ical appliances that
produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless
phones
• Table lamps
• Induction cookers
■Replacing the battery
P.330
■Confirmation of the registered key
number
The number of keys already registered to
the vehicle can be confirmed. Ask your
Lexus dealer for details.
■If “A New Key has been Registered
Contact Your Dealer for Details” is
shown on the multi-information display
This message will be displayed each time
the driver’s door is opened when the doors
are unlocked from the outside for approxi-
mately 10 days after a new electronic key
has been registered.
If this message is disp layed but you have not
had a new electronic key registered, ask your Lexus dealer to check if an unknown
electronic key (other than those in your
possession) has be
en registered.
NOTICE
■To prevent key damage
●Do not drop the keys, subject them to
strong shocks or bend them.
●Do not expose the keys to high tem-
peratures for long periods of time.
●Do not get the keys wet or wash them
in an ultrasonic washer etc.
●Do not attach metallic or magnetic
materials to the keys or place the keys
close to such materials.
●Do not disassemble the keys.
●Do not attach a sticker or anything else
to the surface of the electronic key.
●Do not place the keys near objects that
produce magnetic fields, such as TVs,
audio systems and induction cookers.
●Do not place the keys near medical
electrical equipment such as low-fre-
quency therapy equipment or micro-
wave therapy equipment, and do not
receive medical attent ion with the keys
on your person.
■Carrying the electronic key on your
person
Carry the electronic key 3.9 in. (10 cm)
or more away from electric appliances
that are turned on. Radio waves emitted
from electric applianc es within 3.9 in. (10
cm) of the electronic key may interfere
with the key, causing the key to not func-
tion properly.

Driving
In addition, if an attempt is made to change
the shift position by moving the shift lever or
by pressing the P position switch in any of
the following situations, the buzzer will
sound and the shifting operation will be dis-
abled or the shift position will automatically
change to N. When this happens, select an
appropriate shift position.
●Situations where the shifting operation
will be disabled:
• When an attempt is made to change the
shift position from P to another position
by moving the shift lever without depress-
ing the brake pedal.
• When an attempt is made to change the shift position from P or N to M by moving
the shift lever.
• When the P position switch is pressed
while the vehicle is running.
*1
●Situations where the shift position will
automatically change to N:
• When an attempt is made to select the R position by moving the shift lever when
the vehicle is moving forward.
*2
• When an attempt is made to select the D
position by moving the shift lever when
the vehicle is moving in reverse.
*3
• When the shift position is changed from R to M
●If N is selected while driving at a certain
speed, even if the shift lever is not held in
the N position, the shift position changes
to N. In this situation, the buzzer sounds
and a confirmation message is displayed
on the multi-information display to inform
the driver that the shift position has
changed to N.
*1: Shift position may be changed to P when
driving at extremely low speeds.
*2: Shift position may be changed to R when driving at low speeds.
*3: Shift position may be changed to D when driving at low speeds.
■Reverse warning buzzer
When shifting into R, a buzzer will sound to
inform the driver that the shift position is in
R.
■To protect the automatic transmission
If the automatic transmission fluid tempera-
ture is high, “Transmission Fluid Temp High
See Owner’s Manual” will be displayed on
the multi-information display and the vehi-
cle will go into transmission protection
mode automatically. Have the vehicle
inspected by your Lexus dealer.
■When driving with dynamic radar cruise
control with full-speed range activated
Even when performing the following
actions with the intent of enabling engine
braking, engine braking will not be acti-
vated because dynamic radar cruise con-
trol with full-speed range will not be
canceled.
●While driving in the D position, down-
shifting to 9, 8, 7, 6, 5 or 4.
●When switching the driving mode to
sport mode while driving in D position.

the shift position is in D. (Shifting the shift
position to M cancels the function.)
■If a message about a shift operation is
shown
To prevent the shift position from being
selected incorrectly or the vehicle from
moving unexpectedly, the shift position may
be changed automatically or operating the
