601-4. Hybrid system
QWhen 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).
QWhen 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.
QRegenerative braking
In the following situations, kinetic energy is
converted to electric energy and decelera-
tion force can be obtained in conjunction
with the recharging of the hybrid battery
(traction battery).
OThe accelerator pedal is released while
driving with the shift lever in D or S.
OThe brake pedal is depressed while driv-
ing with the shift lever in D or S.
QEV indicator
The EV indicator comes on when the vehi-
cle is driven using on ly the electric motor
(traction motor) or the gasoline engine is
stopped.
QConditions 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
*:
ODuring gasoline engine warm-up
ODuring hybrid battery (traction battery) charging
OWhen the temperature of the hybrid bat-
tery (traction battery) is high or low
OWhen the heater is switched on
*: Depending on the circumstances, the
gasoline engine may also not stop auto-
matically in other situations.
QCharging 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 10 miles (16 km). If the hybrid
battery (traction battery) becomes fully dis-
charged and you are unable to start the
hybrid system, contact your Lexus dealer.
QCharging the 12-volt battery
 P.393
QAfter 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 your Lexus dealer.
QSounds and vibratio ns 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 lever to P when parked.
The following sounds or vibrations may
occur when the hybrid system is operating
and are not a malfunction:
OMotor sounds may be heard from the
engine compartment.
OSounds may be heard from the hybrid
battery (traction battery) under the rear
seats when the hybrid system starts or
stops.
ORelay operating sounds such as a snap or

2594-6. Driving tips
4
Driving
Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently apply the brakes. A greater
amount of electrical energy can be
regenerated when slowing down.
Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding
overuse of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire
inflation pressure can cause poor fuel
economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel economy.
Use tires that are appropriate for the
season.Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large
roof rack will also cause poor fuel
economy.
Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.

WARNING
QTo prevent the windshield from fog-
ging up
Do not use the windshield defogger
switch during cool air operation in
extremely humid weather. The difference
between the temperature of the outside
air and that of the windshield can cause
the outer surface of the windshield to fog
up, blocking your vision.
QWhen the outside rear view mirror
defoggers are operating
Do not touch the outside rear view mir-
ror surfaces, as they can become very
hot and burn you.
NOTICE
QTo prevent 12-volt battery discharge
Do not leave the air conditioning system
on longer than necessary when the
hybrid system is off.
QWhen repairing/replacing parts of
the air conditioning system
Have repair/replacement performed by
your Lexus dealer. When a part of the air
conditioning system, such as the evapo-
rator, is to be replaced, it must be
replaced with a new one.
