CAUTION
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or seri-
ous injury especially if the driver is very close to the airbag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of inflation,
placing yourself 250 mm (10 in.) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the center of the steering wheel to
your breastbone. If you sit less than 250 mm (10 in.) away now, you can change your
driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals com-
fortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10 in.) dis-
tance, even with the driver seat all the wa y forward, simply by reclining the back of
the seat somewhat. If reclining the back of your seat makes it hard to see the road,
raise yourself by using a firm, non-slippery cushion, or raise the seat if your vehicle
has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommend ed above, while still maintaining control
of the foot pedals, steering wheel, and yo ur view of the instrument panel controls.

■“PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunction in the sys-
tem. Have the vehicle inspected by any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
●Neither “ON” nor “OFF” comes on.
●The indicator light does not change when th e airbag manual on-off switch is switched
to “ON” or “OFF”.
CAUTION
■When installing a child restraint system
For safety reasons, always install a child rest raint system in a rear seat. In the event that
the rear seat cannot be used, the front seat can be used as long as the airbag manual
on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag deployment
(inflation) may cause serious injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which may result in
serious injury or even death.

■Po p U p H o o d p re c a u t i o n s
●Before scrapping your vehicle, make sure to contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
●The Pop Up Hood system cannot be reused once it has operated. Have it replaced by
any authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.
■Conditions under whic h the Pop Up Hood may not operate properly
The Pop Up Hood may not operate properly under the following conditions:
●If a pedestrian collides with the right or left corner of the front bumper or the side of the
vehicle. As such impacts may be difficult to detect, the system may not operate.
●If the vehicle speed is not detected correctly, such as if the vehicle is sliding sideways,
the system may not operate properly.
■Conditions under wh ich the Pop Up Hood may not operate
The Pop Up Hood may not operate in the following situations:
●Colliding with a lying pedestrian
●A frontal impact applied to the front bump er while driving at speeds outside of the
operational speed range
●A side impact or rear impact
●A vehicle rollover (In some accident situations, the Pop Up Hood may operate.)
NOTICE
■Pop Up Hood precautions
●Make sure to close the hood before driving, as the system may not operate properly if
the hood is not fully closed.
●Make sure that all 4 tires are of the specif ied size and inflated to the specified tire
pressure ( →P. 586). If tires of a different size are used, the system may not operate
properly.
●If something has hit the area around the front bumper, the sensors may be damaged
even if the Pop Up Hood has not operated. Have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional.
●Do not remove or repair the parts or wiring of the Pop Up Hood, as doing so may
cause accidental operation or prevent the system from operating properly. If repair or
replacement is necessary, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●Do not remove such components as th e front bumper, hood or suspension, or
replace them with non-genuine parts, as doing so may prevent the system from oper-
ating properly.
●Do not install anything to the front bumper or hood, as doing so may prevent the sen-
sors from detecting an impact correctly and prevent the system from operating prop-
erly.
●Do not close the hood with force or apply load to the lifters, as doing so may damage
the lifters and prevent the system from operating properly.
●Do not modify the suspension, as changes made to the vehicle height may prevent
the system from operating properly.

■After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is being driven by 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 sound or vibration even though the vehicle is able to move. For
safety, apply the parking brake and make sure to shift the shift lever to P when parked.
The following sounds or vibrations may occu r when the hybrid system is operating and
are not a malfunction:
●Motor sounds may be heard from under the vehicle.
●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 hybrid transmission when the hybrid system starts or
stops.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking 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 vents on the both sides of the rear
seatback.
■Maintenance, repair, recycling, and disposal
Contact any authorized Lexus dealer or repa irer, or another duly qualified and equipped
professional regarding maintenance, repair, re cycling and disposal. Do not dispose of the
vehicle yourself.
■Customization
Settings (e.g. on/off operation of the EV indicator) can be changed.
(Customizable features →P. 5 9 1 )

■If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this 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. 5 2 3 )
go off. If there is only a small amount of fu el, 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 10 L [2.7 gal., 2.2 Imp. gal.], when the vehicle is on a level surface. This value may
vary when the vehicle is on a slope.)
■Electromagnetic waves
●High voltage parts and cables on hybrid vehicles incorporate electromagnetic shield-
ing, and therefore emit approximately the same amount of electromagnetic waves as
conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a lim ited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi-
tions.
■Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100 (Battery
electric vehicle safety).
