For safety and security
■Conditions in whic h the gasoline engine may not stop
The gasoline engine starts an d stops automatically. However, it may not stop automati-
cally in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (traction battery) charging
●When the temperature of the hybrid battery (traction battery) is high or low
●When the heater is switched on
■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 reason, be
sure to drive the vehicle at least once every few months for at least 30 minutes or 16 km
(10 miles). If the hybrid battery (traction battery) becomes fully discharged and you are
unable to start the hybrid system, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
■Charging the 12-volt battery
→ P. 5 5 4
■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 battery
(traction battery). If this continues for a few days, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
■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 sa fety, apply the parking brake and make sure
to shift the shift lever to P when parked.
The following sounds or vibrations may occu r when the hybrid system is operating and
are not a malfunction:
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) behind the rear seats
when the hybrid system starts or stops.
●Relay operating sounds such as a snap or soft clank will be emitted from the hybrid bat-
tery (traction battery), behind the rear se ats, when the hybrid system is started or
stopped.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transmission when the gasoline engine starts or stops,
when driving at low speeds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is depressed
or as the accelerator pedal is released.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vents on the both sides of the rear

■When required to leave the vehicle’s key with a parking attendant
Turn the trunk opener main switch off and lock the glove box as circumstances demand.

Remove the mechanical key for your own use and provide the attendant with the elec-
tronic key only.
■If you lose your mechanical keys
New genuine mechanical keys can be made by any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional using the other mechanical key and
the key number stamped on your key number plate. Keep the plate in a safe place such
as your wallet, not in the vehicle.
■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons on the electronic key while inside the ai rcraft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere
with the operation of the aircraft.
■Electronic key battery depletion

half.)
●If the battery becomes low, an alarm will sound in the cabin when the hybrid system
stops. ( →P. 5 1 5 )

even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Replace the battery when necessary. ( →P. 4 5 1 )
• The smart entry & start system or the wireless remote control does not operate.
