Starting off on a steep uphillMake sure that the parking brake is set securely, and then select
shift position D.
Check that the shift position indicator shows D.
Gently depress the accelerator pedal.
Release the parking brake.
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
■Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recom-
mended:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 994 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake sys-
tem needs bedding-down of the brake shoes periodically or whenever the parking
brake shoes and/or drum are replaced. Have your Lexus dealer perform the bed-
ding down operation.

CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid system
operating. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal willresult in sudden acceleration that may lead to an accident that could result in
death or serious injury.
• When backing up, you may twist your body around, leading to a difficulty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, resulting in an acci-
dent.
●The driver should pay extra attention to pedestrians when the vehicle is powered
only by the electric motor (traction motor) . Because there is no engine noise, the
pedestrians may misjudge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.
●Do not let the vehicle roll backward while a forward driving position is selected,
or roll forward while R is selected.
Doing so may result in an accident or damage to the vehicle.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the trunk is closed. Large amounts of exhaust in the vehicle can cause driver
drowsiness and an accident, resulting in death or a serious health hazard. Have
the vehicle inspected by your Lexus dealer immediately.

■Operation of the “POWER” switch
●When operating the “POWER” switch, one short, firm press is enough. If the
switch is pressed improperly, the hybrid system may not start or the “POWER”
switch mode may not change. It is not necessary to press and hold the switch.
●If attempting to restart the hybrid system immediately after turning the
“POWER” switch off, the hybrid system may not start in some cases. After turn-
ing the “POWER” switch off, please wait a few seconds before restarting the
hybrid system.
■Automatically changing to P position
●When the shift position is in a position other than P, pressing the “POWER”
switch with the vehicle stopped completely will cause the shift position to
change to P automatically, and then the “POWER” switch will turn off.
●When turning the “POWER” switch off from a position other than P, firmly
depress the brake pedal and confirm that the shift position* has changed to P
before slowly releasing the brake pedal.
*: Even after the instrument panel display has been turned off, the shift positionindicator will continue to be displayed for several seconds.
●If the P position control system malfunctions, the “POWER” switch will not be
able to be turned off. In such a case, the switch can be turned off by applying the
parking brake.
When the system malfunctions, immediately have your vehicle serviced by your
Lexus dealer.

accelerator pedal while starting the hybrid system under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehicle,
press and hold the “POWER” switch for more than 3 seconds.
However, do not touch the “POWER” switch while driving unless in an emergency.
If the hybrid system stops while driving, this could lead to an unexpected accident.

depressing the brake pedal, and
then press the P position switch.

changed to P, the switch indica-
tor comes on.
Check that the P position indi-
cator is illuminated on the shift

■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 ) .

intersection, the route guidance
will start and the distance
* to the
intersection will also be displayed.
The animation guidance changes
according to the vehicle conditions
(running or stopped).
*:The distance decreases in incre- ments of 50 yards and the dis-
tance indication will disappear
when the vehicle passes through
the intersection.
