For safety and security
◆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 elec-
tric motor (traction motor) is used.
◆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 braking)
The electric motor (traction motor) charges the hybrid battery (traction
battery).
When driving with the gasoline engine stopped, a sound, which changes
in accordance with the driving speed, will be played in order to warn peo-
ple nearby of the vehicle’s approach. The sound will stop when the vehicle
speed exceeds approximately 15 mph (25 km/h).

■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decel-
eration force can be obtained in conjunction with the recharging of the hybrid bat-
tery (traction battery).
●The accelerator pedal is released while driving with the shift position in D or S.
●The brake pedal is depressed while driving with the shift position in D or S.
■EV indicator
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. 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 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 will slowly discharge. For this reason, be
sure to drive the vehicle at least once every few months for at least 30 minutes or
10 miles (16 km). If the hybrid battery becomes fully discharged and you are unable
to jump-start the vehicle with the 12-volt battery, contact your Lexus dealer.
●If the shift lever is in N, the hybrid battery (traction battery) will not be charged.
Always put the shift lever in P when the vehicle is stopped. When driving in heavy
traffic, operate the vehicle with the shift lever in D or S to avoid discharging the bat-
tery.
■Charging the 12-volt battery
→P. 8 1 9
The EV indicator comes on when driving the
vehicle using only the electric motor (traction
motor).

For safety and security
■After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is running on the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.
■Sounds and vibrations specific to a hybrid vehicles
There may be no engine sounds or vibration even though the vehicle is able to move.
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:
●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.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the hybrid transmission when the hybrid system starts
or stops.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is
depressed.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent on rear left seat.
■Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be difficult for
surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of the vehi-
cle, it may be more difficult to hear from the rear of the vehicle compared to the
front.
■Maintenance, repair, recycling, and disposal
Contact your Lexus dealer regarding maintenance, repair, recycling and disposal.
Do not dispose of the vehicle yourself.
■Customization
Settings (e.g. on/off operation of the EV indicator) can be changed.
(Customizable features: → P. 8 6 2 )

■If a warning light comes on, a warning message is displayed, or the 12-volt battery is
disconnected
The hybrid system may not start. In that case, try to start the system again. If the
“READY” indicator does not come on, contact your Lexus dealer.
■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. 762) go off. If there is only a small amount of fuel, the hybrid system may not be
able to start. (The minimum amount of fuel to add to make the low fuel level warning
light go out is about 3.0 gal. [11.3 L, 2.5 Imp.gal.], when the vehicle is on a level sur-
face. This value may vary when the vehicle is on a slope.)
■Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electromagnetic
shielding, and therefore emit approximately the same amount of electromagnetic
waves as conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference 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 change in accordance with driving style and
driving conditions.

ES350_300h_OM_OM33A60U_(U)
Engine immobilizer system (gasoline vehicles)
The indicator light flashes after the
“START STOP ENGINE” switch
has been turned off to indicate that
the system is operating.
The indicator light stops flashing
after the “START STOP ENGINE”
switch has been turned to
ACCESSORY or IGNITION ON
mode to indicate that the system has
been canceled.
■System maintenance
The vehicle has a maintenance-free type engine immobilizer system.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touching a key to the security system (key with a
built-in transponder chip) of another vehicle
The vehicle’s keys have built-in transponder chips that prevent the
engine from starting if a key has no t been previously registered in the
vehicle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
This system is designed to help pr event vehicle theft but does not guar-
antee absolute security agai nst all vehicle thefts.

●The windows and moon roof are closed before the alarm is set.
●No valuables or other personal items are left in the vehicle.
■Triggering of the alarm
The alarm may be triggered in the following situations:
(Stopping the alarm deactivates the alarm system.)
●The 12-volt battery is recharged or replaced when the vehicle is locked. (→P. 8 1 5 )
●A person inside the vehicle opens a door,
the trunk or hood.
