Before driving
■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 shift position D or B
selected.
●The brake pedal is depressed while driving with shift position D or B selected.
■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
*: However, when the hybrid battery (traction battery) need to be
charged or while the engine is being warmed up, the gasoline
engine may not stop automatically.
■ During normal driving
The gasoline engine is predomina ntly used. The electric motor
(tr
action motor) charges the hybrid battery as necessary.
■ When acceler
ating sharply
The power of the hybrid battery (tract ion batter
y) is added to that of
the gasoline engine via the electric motor (traction motor).
■ When br
aking (regenerative braking)
The electric motor (traction motor) char
ges the hybrid battery
(traction battery).

1-1. Hybrid system
■Air conditioning
Use the air conditioning only when necessary. Doing so can help control
excessive gasoline consumption. 
In summer: In high temperatures, use the r
ecirculated air mode. Doing so
will help to reduce the burden on the air conditioner and reduce fuel con -
sumption as well. 
In winter: Because the gasoline engine will not automatically cut out until
the gasoline
engine and the interior of the vehicle are warm, it will con -
sume fuel. Also, fuel consumption can be impr
oved by avoiding overuse of
the heater.
■ Checking tire inflation pressure
Make sure to check the tire inflatio n pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption. 
Also, as snow tires can cause large amounts of friction, their use on dry
r
oads can lead to poor fuel consumptio n. Use a tire that is appropriate for
the season.
■ Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid carry-
ing unnecessary luggage. Installing a la r
ge roof rack can also cause poor
fuel consumption.
■ Warming up before driving
Since the gasoline engine starts up and cuts out automatically when cold,
warming up the engine is unnecessary. Moreover, frequently driving short
distances will cause the engine to repeatedly warm up, which can lead to
poor fuel consumption.

NOTICE
■Camera sensor
●Keep the windshield clean at all times.
LKA performance may deteriorate due to the presence of raindrops, condensa-
tion, ice or snow on the windshield.
●Do not attach a sticker or other items to the windshield near the camera sensor.
●When adjusting the rear-view mirror, make sure that it does not block the camera
lens.
●When it is cold, using the heater with air blowing to the feet may allow the upper
part of the windshield to fog up. This will have a negative effect on the images. In
such a case, use the windshield defogger to provide warm, dry air to the wind-
shield.
●Do not place anything on the dashboard.
The camera sensor may recognize the image reflected on the windshield as lane
markers by mistake.
●Do not scratch the camera lens, or let it get dirty.
●Do not change the installation position of the camera sensor or remove it. The
direction of the camera sensor is precisely adjusted.
●Do not subject the camera sensor to stro ng impact or force, and do not disas-
semble the camera sensor.
Observe the following to ensure that the LKA
system functions correctly.

Front side outlets
Direct air flow to the left or right,
up or down.
Turn the knob to open or close
the vent.
Rear outlets Direct air flow to the left or right,
up or down.
Turn the knob to open or close
the vent.
■Air conditioning system settings
When the “POWER” switch is turned on, the a
ir conditioning system settings will be
set to those that were in use the last time the “POWER” switch was turned off.
●Air conditioning system settings are memorized individually on each electronic
key, so the settings reproduced will be specific to the key that is used.
●This feature is customizable at your Lexus dealer.
■Using automatic mode
Fan speed is adjusted automatically acco r
ding to the temperature setting and ambi-
ent conditions. As a result, the following may occur:
●The system may switch automatically to recirculated air mode when the coolest
temperature setting is selected when the ambient temperature is high.
●Immediately after the button is pressed, the fan may stop for a while until warm
or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.

CAUTION
■Burns
●Use caution when seating the following persons in a seat with the seat heater on
to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically challenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or dr ugs that induce sleep (sleeping drugs,
cold remedies, etc.)
●Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature of the
seat and may lead to overheating.
●Do not use the seat heater more than necessary. Doing so may cause minor
burns or overheating.
NOTICE
■To prevent damage to the seat heaters/ventilators
Do not put heavy objects that have an unev en surface on the seat and do not stick
sharp objects (needles, nail s, etc.) into the seat.
■To prevent 12-volt battery discharge
Turn the seat heaters/ventilators off when the hybrid system is off.

4-1. Maintenance and care
NOTICE
■Cleaning detergents
Do not use the following types of detergent, as they may discolor the vehicle inte-
rior or cause streaks or damage to painted surfaces:
●Non-seat portions: Organic substances such as benzene or gasoline, alkaline or
acidic solutions, dye, and bleach
●Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
■Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of leather
surfaces:
●Remove any dust or dirt from leather surfaces immediately.
●Do not expose the vehicle to direct sunlight for extended pe riods of time. Park
the vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or containing wax on the upholstery, as
they may stick to the leather surface if the vehicle interior heats up significantly.
■Water on the floor
Do not wash the vehicle floor with water. 
Vehicle systems such as the audio system may be damaged if water comes into
contact with electrical components such as the audio system above or under the
floor of the vehicle. Water may also cause the body to rust.
■Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause damage to
the rear window defogger heater wires or antenna. Use a cloth dampened with
lukewarm water to gently wipe the window clean. Wipe the window in strokes
running parallel to the heater wires or antenna.
●Be careful not to scratch or damage the heater wires or antenna.
