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 16 km (10 miles). If the hybrid bat-
tery becomes fully discharged and you are unable to jump-start the vehi-
cle with the 12-volt battery, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
If the shift position is in N, the hybrid battery (traction battery) will not
be charged. Always shift the shift position in P when the vehicle is
stopped. When driving in heavy traffic, operate the vehicle with the shift
position in D or B to avoid discharging the hybrid battery (traction bat-
tery).
Charging the 12-volt battery
P. 6 3 6
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 any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.

Sounds and vibrations specific to a hybrid vehicle
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 may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
Engine sounds may be heard when accelerating sharply.
Sounds may be heard due to regenerative braking when the brake pedal
is depressed and accelerator is loosened.
Other sounds, such as motors and mechanical noises, may be heard from
the brake system 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 the side of
rear right seatback.
Maintenance, repair, recycling, and disposal
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.
Customization
Settings (e.g. on/off operation of the EV indicator) can be changed.
(Customizable features P. 667)

Hybrid system precautions
Take care when handling the hybrid system, as it contains a high volt-
age system (about 650V at maximum) as well as parts that become
extremely hot when the hybrid system is operating. Obey the caution
labels attached to the vehicle.

Hybrid battery air vent
There is an air intake vent on
the side of the rear right seat-
back for the purpose of cooling
the hybrid battery (traction bat-
tery). If the vent become
blocked, the hybrid battery may
overheat, leading to a reduction
in hybrid battery output.
Emergency shut off system
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel
leakage. If the emergency shut off system activates, your vehicle
will not restart. To restart the hybrid system, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and
equipped professional.

Hybrid warning message
A message is automatically displayed when a malfunction occurs
in the hybrid system or an improper operation is attempted.
If a warning message is shown
on the multi-information dis-
play, read the message and fol-
low the instructions.
(P. 578)
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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
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. 575) 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 11.8 L [3.1 gal.,
2.6 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)

NOTICE
Hybrid battery air vent
Do not put foreign objects near the air vent. The hybrid battery (traction
battery) may overheat and be damaged.
Clean the air vent regularly to prevent the hybrid battery (traction battery)
from overheating.
Do not wet or allow foreign substances to enter the air vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the bat-
tery may be damaged. Have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.

Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/cooling) will be minimized, improv-
ing the fuel economy.
(P. 209)
Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. (P. 222)
When braking the vehicle
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel consumption. Check traffic
reports before leaving and avoid delays as much as possible. When
encountering a delay, gently release the brake pedal to allow the
vehicle to move forward slightly while avoiding overuse of the
accelerator pedal. Doing so can help control excessive gasoline
consumption.
Highway driving
Control your speed and keep at a constant speed. Also, before stop-
ping at a toll booth or similar, allow plenty of time to release the
ldllhbkA fli

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, frequently
driving short distances will cause the engine to repeatedly warm up,
which can lead to poor fuel consumption.
