■Charging the 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-volt battery, contact your Lexus dealer.
■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 your Lexus dealer.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to
move. Always change 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 from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transaxle when the hybrid system starts or stops,
or while the vehicle is 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 left
seatback.
When driving in Eco mode, the fan noise may be louder than when driving nor-
mally.
■Maintenance, repair, recycling, and disposal
Contact your Lexus dealer regarding maintenance, repair, recycling and disposal.
Do not dispose of the vehicle yourself.

Active head restraints
When the occupant’s lower back
presses against the seatback dur-
ing a rear-end collision, the head
restraint moves slightly forward
and upward to help reduce the risk
of whiplash on the seat occupant.
■The auto away function for exiting the driver seat
If the seat is already close to the rearmost position, the auto away function may not
operate when the driver exits the vehicle.
■Active head restraints
Even small forces applied to the seatback may cause the head restraint to move.
Pushing up a locked head restraint forcibly may appear the head restraint inner
structure. These do not indicate problems.
■Customization
The distance that the driver’s seat moves backward during the auto away function
can be changed. (Customizable features →P. 5 74 )

■Operating the driving position memory after turning the “POWER” switch off
Memorized positions (except for the steering wheel position) can be activated up
to 180 seconds after the driver’s door is opened and another 60 seconds after it is
closed again, even after turning the “POWER” switch off.
■Canceling the linked door unlock operation
Turn the “POWER” switch to ON mode and close the driver’s door.
While pressing the “SET” button, press the driver’s door lock switches
(either lock or unlock) until the signal beeps.
■Stopping seat position operation part-way through
Perform any of the following operations:
●Press the “SET” button.
●Press button 1, 2 or 3.
●Adjust the seat using the switches (only cancels seat position recall).
●Adjust the steering wheel using the tilt and telescopic steering control switch
(only cancels steering wheel position recall).
■Correct seat position
When the seat is in the most forward or most backward position, and the seat is
being moved in those directions, the system may not correctly recognize the cur-
rent position and the memorized position will not be correctly recalled.
■Customization
If a seat position is memorized, the driver seat will move back the set distance
(→ P. 574) from that memorized position.
CAUTION
■Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passenger
or squeeze your body against the steering wheel.

Seat belts
Make sure that all occupants are wearing their seat belts before driving the
vehicle.
■Correct use of the seat belts
●Extend the shoulder belt so
that it comes fully over the
shoulder, but does not come
into contact with the neck or
slide off the shoulder.
● Position the lap belt as low as
possible over the hips.
● Adjust the position of the
seatback. Sit up straight and
well back in the seat.
● Do not twist the seat belt.
■ Fastening and releasing the seat belt

■Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for the
first collision, but will not activate for the second or subsequent collisions.
■Seat belt extender
CAUTION
■Wearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of sudden
braking, sudden swerving or an accident.
Failing to do so may cause death or serious injury.
●Ensure that all passengers wear a seat belt.
●Always wear a seat belt properly.
●Each seat belt should be used by one person only. Do not use a seat belt for more
than one person at once, including children.
●Lexus recommends that children be seated in the rear seat and always use a seat
belt and/or an appropriate child restraint system.
●To achieve a proper seating position, do not recline the seat more than necessary.
The seat belt is most effective when the occupants are sitting up straight and well
back in the seats.
●Do not wear the shoulder belt under your arm.
●Always wear your seat belt low and snug across your hips.
If your seat belts cannot be fastened securely
because they are not long enough, a person-
alized seat belt extender is available from
your Lexus dealer free of charge.

CAUTION
■While driving
●Do not adjust the position of the driver’s seat.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the
effectiveness of the seat belt and head restraint, increasing the risk of death or
serious injury to the driver or passenger.
●Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat tracks and
stop the seat from locking in place. This may lead to an accident, resulting in
death or serious injury. The adjustment mechanism may also be damaged.
■Adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are
not injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the seat mechanism.

CAUTION
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can
cause death or serious injury especially if the front passenger is very close to the
airbag. The front passenger seat should be as far from the airbag as possible with
the seatback adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infants and children can be killed or seri-
ously injured by a deploying airbag. An infant or child who is too small to use a
seat belt should be properly secured using a child restraint system. Lexus strongly
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats are safer for infants and children than the
front passenger seat. (→P. 121)
●If the seat belt extender has been con-
nected to the driver’s seat belt buckle but
the seat belt extender has not also been
fastened to the latch plate of the driver’s
seat belt, the SRS driver airbag system will
judge that the driver is wearing the seat belt
even though the seat belt has not been
connected. In this case, the SRS driver
airbag may not activate correctly in a colli-
sion, resulting in death or serious injury in
the event of a collision. Be sure to wear the
seat belt with the seat belt extender.
