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.416) go off. If there is only a small

amount of fuel, the hybrid system may not

be able to start. (The standard amount of

fuel is about 7.5 L [2.0 gal., 1.7 Imp.gal.],

when the vehicle is on a level surface. This

value may vary when the vehicle is on a

slope. Add extra fuel when the vehicle is

inclined.)

Electromagnetic waves

High voltage parts and cables on hybrid

vehicles incorporate electromagnetic

shielding, and therefore emit approxi-

mately the same amount of electromag-

netic waves as conventional gasoline

powered vehicles or home electronic

appliances.

Your vehicle may cause sound interfer-

ence in some third party-produced radio

parts.

Hybrid battery (traction battery)

The hybrid battery (traction battery) has a

limited service life. The lifespan of the

hybrid battery (traction battery) can change

in accordance with driving style and driving

conditions.

Declaration of conformity

This model conforms to hydrogen emis-

sions according to regulation ECE100

(Battery electric vehicle safety).

WARNING

High voltage precautions

This vehicle has high voltage DC and AC

systems as well as a 12-volt system. DC

and AC high voltage is very dangerous

and can cause severe burns and electric

shock that may result in death or serious

injury.

Never touch, disassemble, remove or

replace the high voltage parts, cables

or their connectors.

The hybrid system will become hot

after starting as the system uses high

voltage. Be careful of both the high

voltage and the high temperature, and

always obey the warning labels

attached to the vehicle.

Never try to open the service plug

access hole located underneath the

rear seats. The service plug is used

only when the vehicle is serviced and is

subject to high voltage.

Road accident cautions

Observe the following precautions to

reduce the risk of death or serious injury:

Pull your vehicle off the road, shift the

shift lever to P, apply the parking

brake, and turn the hybrid system off.

Do not touch the high voltage parts,

cables and connectors.

d s

uri

WARNING

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 the

fluid as it may be strong alkaline elec-

trolyte from the hybrid battery (trac-

tion 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 solu-

tion. Seek immediate medical atten-

tion.

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 danger-

ous.

If your vehicle needs to be towed, do

so with front wheels (2WD models) or

four wheels (AWD models) raised. If

the wheels connected to the electric

motor (traction motor) are on the

ground when towing, the motor may

continue to generate electricity. This

may cause a fire. (



P.407)

Carefully inspect the ground under the

vehicle. If you find that liquid has

leaked onto the ground, the fuel sys-

tem may have been damaged. Leave

the vehicle as soon as possible.

Hybrid battery (traction battery)

Never resell, hand over or modify the

hybrid battery. To prevent accidents,

hybrid batteries that have been

removed from a disposed vehicle are

collected through any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer. Do

not dispose of the battery yourself.

Unless the battery is properly collected,
the following may occur, resulting in
death or serious injury:
• The hybrid battery may be illegally dis-

posed of or dumped, and it is hazard-

ous to the environment or someone

may touch a high voltage part, result-

ing in an electric shock.

• The hybrid battery is intended to be

used exclusively with your hybrid vehi-

cle. If the hybrid battery is used outside

of your vehicle or modified in any way,

accidents such as electric shock, heat

generation, smoke generation, an

explosion and electrolyte leakage may

occur.

When reselling or handing over your

vehicle, the possibility of an accident is

extremely high because the person

receiving the vehicle may not be aware

of these dangers.

If your vehicle is disposed of without

the hybrid battery having been

removed, there is a danger of serious

electric shock if high voltage parts,

cables and their connectors are

touched. In the event that your vehicle

must be disposed of, the hybrid battery

must be disposed of by any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer. If the

hybrid battery is not disposed of prop-

erly, it may cause electric shock that

can result in death or serious injury.

1-4. Hybrid system

There is an air intake vent under the
right side of the rear seat for the pur-
pose of cooling the hybrid battery
(traction battery). If the vent become
blocked, the hybrid battery input and
output may be restricted, leading to a
reduction in hybrid battery (traction
battery) output.

When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks the
high voltage current and stops the fuel
pump to minimize the risk of electrocu-
tion and fuel leakage. If the emergency
shut off system activates, your vehicle
will not restart. To restart the hybrid
system, contact any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer.

A message is automatically displayed
when a malfunction occurs in the
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the
multi-information display, read the
message and follow the instructions.

NOTICE
