■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 auto matically. However, it may not stop auto-
matically in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (t raction 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-v olt battery, contact your Lexus dealer.
●If the shift lever is in N, the hybrid ba ttery (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 le ver in D or S to avoid discharging the bat-
tery.
■Charging the 12-volt battery
 P. 5 6 3
The EV indicator comes on when the vehicle
is driven using only the electric motor (trac-
tion motor) or the gasoline engine is stopped.

NOTICE
■Camera sensor (P. 2 7 0 )
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, conden-
sation 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 ai r 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 your Lexus dealer.
●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 stro ng impact or force, and do not disas-
semble 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.

4-5. Using the driving support systems
■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. 335). To improve air condition-
ing performance, adjust the fan sp eed 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 conditioning
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 automatically operated to
assist heating performance.
■Sport mode automatic deactivation
Sport mode is automatically deactivated if th e power switch is turned off after driving
in sport mode.

Driving
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help con-
trol 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 eng ine will not automatically cut out
until the gasoline engine and the interi or 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 consump tion. Use a tire that is appropriate
for the season.
◆Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid car-
rying 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 unne cessary. Moreover, frequently driv-
ing short distances will cause the engine to repeatedly warm up, which
can lead to poor fuel consumption.

5-2. Using the air conditioning system and defogger
With rear air conditioning system
When “3-ZONE” on the option control screen is selected (the indicator will be
on) or the passenger’s side temperature control button is pressed, the tempera-
ture for the driver’s, front passenger’s and rear seats ( P. 355) can be adjusted
separately.
Air outlets and fan speed for the driver and passenger seats may be adjusted sep-
arately depending on the temperature setting.
When the front seat heaters and ventilators/rear seat heaters are set to AUTO
mode, the system is operated automatically according to the set temperature,
outside temperature, etc.
■Automatic mode indicator
If the fan speed setting or air flo w modes are operated, the automatic
mode indicator goes off. However, automatic mode for functions other
than that operated is maintained.
