Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained 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 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
automatically 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 bat-
tery 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 dis-
charge. 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
becomes fully discharged and you are unable to jump-start the vehicle with
the 12-volt battery, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
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 battery.
Charging the 12-volt battery
P. 9 1 2 The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.

NOTICE
Camera sensor (P. 338)
Observe the following to ensure that the LKA system functions correctly.
Keep the windshield clean at all times.
Performance could be affected if the windshield is dirty, or if raindrops,
condensation or ice are adhering to the windshield.
When adjusting the rear view mirror, make sure that it does not block the
camera lens.
Do not attach window tinting to the windshield.
Do not install an antenna in front of the camera lens.
If the windshield is fogged up, use the windshield defogger to remove fog
from the windshield.
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.
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.
When cleaning the inside of the windshield, be careful not to get any glass
cleaner etc. on the lens. Also, do not touch the lens.
For lens repair, contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
Do not change the installation position or direction of the camera sensor
or remove it. The direction of the camera sensor is precisely adjusted.
Do not subject the camera sensor to strong impact or force, and do not dis-
assemble the camera sensor.
Do not attach a sticker or other items to
the windshield near the camera sensor.
Do not install or place anything near the
camera.

Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency (P. 478). To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
Automatic operation of the seat heater during Eco drive mode
Eco drive mode controls the heating operation and fan speed of the air condi-
tioning system to enhance fuel efficiency. If the driving mode select switch is
switched to Eco drive mode in cold temperatures, the seat heater will be auto-
matically operated to assist heating performance.
Sport mode automatic deactivation
Sport mode is automatically deactivated if the power switch is turned off
after driving in sport mode.
Operation of the Eco drive mode (on some models)
The driving mode will set to Eco drive mode each time the power switch is
turned to ON mode.

the accelerator and gently apply the brakes. A greater amount of
electrical energy can be retained when slowing down.
Air conditioning
Use the air conditioning only when necessary. Doing so can help
control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce the burden on the air conditioner
and reduce fuel consumption 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 consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
Checking tire inflation pressure
Make sure to check the tire inflation 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 roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
Luggage
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large 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, fre-
quently driving short distances will cause the engine to repeat-
edly warm up, which can lead to poor fuel consumption.
