1-1. Hybrid system
HS250h_U_75050U
■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-volt battery, contact your Lexus dealer.
■Charging the 12-volt battery
→P. 5 4 9
■After the 12-volt battery has discharg ed 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. 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 from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transaxle when the engine is started or stopped,
or while the engine 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 drive mode, the fan noise may be louder than when driving
normally.

CAUTION
■To prevent an accident
Observe the following precautions while driving the vehicle.
Failure to do so may result in a door opening and an occupant falling out, resulting
in death or serious injury.
●Always use a seat belt.
●Always lock all the doors.
●Ensure that all doors are properly closed.
●Do not pull the inside handle of the doors while driving.
The doors may be opened and the passengers are thrown out of the vehicle and it
may result in serious injury or death.
Be especially careful for the front doors, as the doors may be opened even if the
inside lock buttons are in locked position.
●Set the rear door child-protector locks when children are seated in the rear seats.

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 8 4 )
