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.
