CAUTION
• Soft drink cans may fracture, causing the contents to spray over the interior ofthe vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such
as the glove box or on the floor, it may be lit accidentally when luggage is loaded
or the seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windshield or windows. Do not place contain-
ers such as air fresheners on the instrument panel or dashboard. Adhesive discs
or containers may act as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if the curved glass is coated with a metal-
lized film such as a silver-colored one. Reflected sunlight may cause the glass to
act as a lens, causing a fire.
●Always apply the parking brake, select shift position P, stop the hybrid system,
and lock the vehicle.
Do not leave the vehicle unattended while the hybrid system is operating.
●Do not touch the exhaust pipe while the hybrid system is operating or immedi-
ately after turning the hybrid system off.
Doing so may cause burns.
●Do not leave the hybrid system operating in an area with snow build-up, or where
it is snowing. If snowbanks build up around the vehicle while the hybrid system is
operating, exhaust gases may collect and enter the vehicle. This may lead to
death or a serious health hazard.
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health hazard.
●If the vehicle is in a poorly ventilated area, stop the hybrid system. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle. This may
lead to death or a serious health hazard.
●The exhaust system should be checked occasionally. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be sure to
have the vehicle inspected and repaired by your Lexus dealer. Failure to do so
may allow exhaust gases to enter the vehicle, resulting in death or a serious health
hazard.

CAUTION
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an accident or fire due to
hybrid system overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to death or a
serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side
of the vehicle to brake differently than the other side. Also, the parking brake may
not securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other vehicles
closely and avoid downhill or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the pedal than
usual. Braking distance may also increase.
●The brake system consists of 2 individual hydraulic systems; if one of the systems
fails, the others will still operate. In this case, the brake pedal should be depressed
more firmly than usual and the braking distance will increase. If this happens, do
not continue to drive the vehicle. If the brake system warning light (red indicator)
comes on while driving, immediately stop the vehicle in a safe place and contact
your Lexus dealer.
NOTICE
■When driving the vehicle
Do not use the accelerator pedal or depress the accelerator and brake pedals at
the same time to hold the vehicle on a hill.
■When parking the vehicle
Be sure to firmly apply the parking brake and set the shift position to P. Failure to do
so may cause the vehicle to move or the vehicle may accelerate suddenly if the
accelerator pedal is accidentally depressed.

NOTICE
■To prevent 12-volt battery discharge
●Do not leave the “POWER” switch in ACCESSORY or ON mode for long peri-
ods of time without the hybrid system on.
●If the hybrid system is off, but the indicator on the “POWER” switch is illuminated,
this indicates that the “POWER” switch is still turned on. When exiting the vehi-
cle, always check that the “POWER” switch is off.
■When starting the hybrid system
Do not depress the accelerator pedal unnecessarily.
■Symptoms indicating a malfunction with the “POWER” switch
If the “POWER” switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact your Lexus
dealer immediately.

■Limitations of brightness adjustment
The brightness of the instrument panel lights is automatically adjusted based on the
light sensor detecting how bright the surroundings are. However, if the instrument
panel brightness has been manually set to either the brightest or dimmest setting,
the automatic adjustment will not be performed.
■Hybrid System Indicator
●By keeping the indicator needle within Eco area, environmentally-friendly driv-
ing can be achieved.
Hybrid Eco area shows that gasoline engine power is not being used very often.*

●Charge area indicates regeneration*2 status. Regenerated energy will be used
to charge the hybrid battery.
*
1: The gasoline engine will automatically stop and restart under various condi- tions.
*
2: When used in this manual, “regeneration” refers to the conversion of energy created by the movement of the vehicle into electrical energy.
■Customization
Settings (e.g. Sensitivity of the ambient light sensor used for dimming the meter
lights) can be changed. (Customizable features →P. 5 74 )
NOTICE
■To prevent damage to the hybrid system and its components
A high engine coolant temperature warning light (→ P. 492) is installed instead of
an engine coolant temperature gauge. If the high engine coolant temperature
warning light illuminates or flashes, the vehicle may be overheating. Immediately
stop the vehicle in a safe area ( →P. 5 4 1 ) .
