Important points for the hybrid system

Hybrid system features

Your vehicle is a hybrid electric vehicle. It has characteristics different from con-
ventional vehicles. Be sure you are closely familiar with the characteristics of your
vehicle, and operate it with care. The hybrid system combines the use of a gasoline
engine and an electric motor (traction motor) according to driving conditions,
improving fuel efficiency and reducing exhaust emissions.

WARNING

The driver should pay extra attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). As there is no engine noise, the pedestrians may
misjudge the vehicle's movement. Even though the vehicle is equipped with the acoustic
vehicle alerting system, drive with care as pedestrians in the vicinity may still not notice
the vehicle if the surrounding area is noisy.

■

When stopped/during start off

The gasoline engine stops

when the vehicle is stopped.

During start off, the electric motor (traction motor) drives the vehicle.
At slow speeds or when traveling down a gentle slope, the engine is stopped

and

the electric motor (traction motor) is used.
When the shift position is in N, the hybrid battery (traction battery) is not being
charged.

■

During normal driving

The gasoline engine is predominantly used.
The electric motor (traction motor) charges the hybrid battery (traction battery) as
necessary.

INFORMATION

■

Conditions in which the gasoline engine may not stop

The gasoline engine starts and stops automatically.

●

During gasoline engine warm-up

●

During hybrid battery (traction battery) charging

●

When the temperature of the hybrid battery (traction battery) is high or low

●

When the heater is switched on

*1 :

When the hybrid battery (traction battery) requires charging or the engine is warming

up, etc., the gasoline engine will not automatically stop.

*2 :

Depending on the circumstances, the gasoline engine may also not stop automatical-

ly in other situations.

(traction battery).
If this continues for a few days, contact your Lexus dealer.

■

Hybrid battery (traction battery) lifespan

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 condi-
tions.

■

Starting the hybrid system in an extremely cold environment

When the hybrid battery (traction battery) is extremely cold (below approximately -22°F
[-30°C]) under the influence of the outside temperature, it may not be possible to start
the hybrid system. In this case, try to start the hybrid system again after the temperature
of the hybrid battery increases due to the outside temperature increase etc.

Acoustic vehicle alerting system

When driving with the gasoline engine stopped, a sound, which changes in ac-
cordance with the driving speed, will be played in order to warn people nearby
of the vehicle’s approach. The sound will stop when the vehicle speed exceeds

Hybrid system precautions

Take care when handling the hybrid system, as it is a high voltage system (about
650 V at maximum) as well as contains parts that become extremely hot when the
hybrid system is operating. Obey the warning labels attached to the vehicle.

WARNING

■

High voltage precautions

This vehicle has high voltage DC and AC systems as well as a 12-volt system.
Observe the following, otherwise you may suffer burns or electric shock.

●

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 lo-
cated underneath the rear seats. The service plug
is used only when the vehicle is serviced and is
subject to high voltage.

■

If the vehicle is involved in a collision

Observe the following.

●

Stop the vehicle in a safe place to prevent subsequent accidents. While depressing the
brake pedal, apply the parking brake and shift the shift position to P to stop the hybrid
system. Then, slowly release the brake pedal.

●

Do not touch the high voltage parts, cables and connectors.

●

Never touch exposed electric wires. If electric wires are exposed inside or outside
your vehicle, an electric shock may occur.

●

Do not touch fluid, if attached to or leaking, as the fluid may be electrolyte of the hybrid
battery (traction battery), which is organic electrolyte mainly consisting of carbonate
ester.
If the electrolyte of the hybrid battery (traction battery), which is organic electrolyte
mainly consisting of carbonate ester, comes into contact with your eyes or skin, it may
cause blindness or injury to the skin. If it comes into contact with your eyes or skin,
wash it off immediately with a large amount of water, and seek immediate medical
attention.

1-2. Important points for the hybrid system

WARNING

●

If electrolyte is leaking from the hybrid battery (traction battery), do not approach the
vehicle.
Even in the unlikely event that the hybrid battery (traction battery) is damaged, the
internal construction of the battery will prevent a large amount of electrolyte from
leaking out. However, any electrolyte that does leak out will give off a vapor. This vapor
is an irritant to skin and eyes and could cause acute poisoning if inhaled.

●

Do not bring burning or high-temperature items close to the electrolyte.
The electrolyte may ignite and cause a fire.

●

If a fire occurs in the hybrid electric 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 four wheels 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.

●

Check the ground under the vehicle. If a liquid other than water from the air condition-
ing system is found, the fuel system may have been damaged.
Do not start the hybrid system. If it is started as is, the leaked fuel may ignite.
Leave the vehicle as soon as possible, and contact your Lexus dealer.

INFORMATION

Check that the shoulder belt is correctly posi-
tioned over the child’s shoulder and that the lap
belt is as low as possible.

WARNING

■

When installing a child restraint system

Observe the following precautions. Failure to do so may result in death or serious
injury.
When a booster seat is installed, always ensure that the shoulder belt is positioned
across the center of the child’s shoulder. The belt should be kept away from the child’s
neck, but not so that it could fall off the child’s shoulder.

■

When installing a booster seat

To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten only. This could cause injury or discomfort
to the child.

Removing a child restraint system

●

Press the buckle release button and fully re-
tract the seat belt.

When releasing the buckle, the child restraint sys-
tem may spring up due to the rebound of the seat
cushion. Release the buckle while holding down the
child restraint system.
Since the seat belt automatically reels itself, slowly
return it to the stowing position.
