1-1. Hybrid system
CAUTION
■Road accident cautions
Observe the following precautions to reduce the risk of injury.
●Pull your vehicle off the road, put the shift lever in “P”, apply the parking brake,
turn the hybrid system off.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric shock may
occur. Never touch exposed electric wires.
●If a fluid leak occurs, do not touch it as it may be strong alkaline electrolyte from
the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or if possible, boric
acid solution. Seek immediate medical attention.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never
use a fire extinguisher that is not meant for electric fires. Using even a small
amount of water may be dangerous.
●If your vehicle needs to be towed, do so with the rear wheels raised. If the wheels
with the electric motor (t raction motor) are on the ground when towing, the
motor may continue to generate electricit y. This may cause an electricity leakage
leading to a fire.(
P. 4 2 0 )
■Nickel-metal hydride battery
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of improp-
erly, it is hazardous to the environment and there is a risk of severe burns and elec-
trical shock that may result in death or serious injury.
■Emergency shut off system
●Carefully check to see if there are exposed high voltage parts or cables. Never
touch the parts or cables. (
P. 5 )
●Carefully inspect the ground under the vehicle. If you find that liquid has leaked
onto the ground, the fuel system may have been damaged. Leave the vehicle as
soon as possible.

dows are closed.
■ Opening the fuel tank cap
Press the fuel filler door
opener switch.
The screen to the left is dis-
played for a short period. Wait

CAUTION
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so, may
result in death or serious injury.
●Touch the vehicle or some other metal surface to discharge any static electricity.
Sparks resulting from discharging static electricity may cause the fuel vapors to
ignite.
●Always hold the grips on the fuel tank cap and turn it slowly to remove it. 
A whooshing sound may be heard when the fuel tank cap is loosened. Wait until
the sound cannot be heard before fully re moving the cap. In hot weather, pressur-
ized fuel may spray out the filler neck and cause injury.
●Do not allow anyone that has not discharged static electricity from their bodies to
come close to an open fuel tank.
●Do not inhale vaporized fuel. 
Fuel contains substances that are harmful if inhaled.
●Do not smoke while refueling the vehicle. 
Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch an y person or object that is statically
charged. 
This may cause static electricity to build up , resulting in a possible ignition hazard.
If the fuel filler door opener switch is inopera-
ble, contact your Lexus dealer to service the
vehicle. If you must refuel your vehicle, you
can open the fuel filler door manually as
shown. The system to lower internal pressure
may not be functioning so you must turn the
cap slowly as the pressure releases. In addi-
tion, fuel may spill out during refueling. Fill the
fuel tank carefully and slowly.

Before driving
CAUTION
■When replacing the fuel tank cap
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
Failure to do so may cause a fire or other incident which may result in death or seri-
ous injury.
NOTICE
■Refueling
●Finish refueling within 30 minutes. If more than 30 minutes passes, the internal
valve closes. In this condition, fuel may overflow during the refueling process.
Press the fuel filler d oor opener switch again.
●Do not spill fuel during refueling. 
Failing to do so may damage the vehicle, such as causing the exhaust systems to
operate abnormally or damaging fuel system components or the vehicle's
painted surface.

2-1. Driving procedures

When driving
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
obser
ve:
●For the first 186 miles (300 km): 
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
co
rrect fuel. ( P. 4 8 2 )
■For efficient use
●Put the shift lever into “D” when driving 
In the “N” position, the gasoline engine operates but electricity cannot be gen -
erated. The hybrid ba tter
y (traction battery) will be discharged requiring unnec-
essary engine power to recharge.
●Drive your vehicle smoothly 
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel -
eration will make more effective use of the traction motor without having to use
g
asoline engine power.
●Avoid repeated acceleration 
Repeated acceleration consumes hybrid battery (traction battery) power,
r
esulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
●Put the shift lever into “P” when parking 
In the “N” position, the hybrid battery (traction battery) does not recharge. 
Leaving the shift lever in the “N” position for an extended period of the time may
di
scharge the hybrid battery. The vehicle cannot run if the hybrid battery is dis-
charged.
■When starting on an incline
The hill-start assist control may operate. ( P. 1 6 2 )
