LEXUS RX 450HL (2019 year). Instruction

1-3. Hybrid system

RX450h_RX450hL_U

■

If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-

connected
The hybrid system may not start. In this case, try to start the system again. If the “READY”

indicator does not come on, contact your Lexus dealer.

■

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. 662)

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 2.9 gal. [11.0 L, 2.4 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 shield-

ing, and therefore emit approximately the same amount of electromagnetic waves as

conventional gasoline powered vehicles or home electronic appliances.

●

Your vehicle may cause sound interference 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 condi-

tions.

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 warn-

ing labels attached to the vehicle.

●

Never try to open the service plug access

hole located under the rear seat. The service

plug is used only when the vehicle is serviced

and is subject to high voltage.

WARNING

■

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.

●

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 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 all four wheels raised. If the wheels con-

nected 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. 654)

●

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.

■

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

Lexus dealer. 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 disposed of or dumped, and it is hazardous to

the environment or someone may touch a high voltage part, resulting in an electric

shock.

• The hybrid battery is intended to be used exclusively with your hybrid vehicle. 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 elec-

trolyte 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 your Lexus dealer or a qualified service shop. If the hybrid bat-

tery is not disposed of properly, it may cause electric shock that can result in death or

serious injury.

NOTICE

■

Hybrid battery (traction battery) air intake/discharge vents

●

Do not place objects that will block the air intake vents. The hybrid battery (traction

battery) may overheat and be damaged.

●

Clean the air intake/discharge vents regularly to prevent the hybrid battery (traction

battery) from overheating.

●

Do not get water or foreign materials in either the air intake/discharge vents as this

may cause a short circuit and damage the hybrid battery (traction battery).

●

Do not carry large amounts of water such as water cooler bottles in the vehicle. If

water spills onto the hybrid battery (traction battery), the battery may be damaged.

Have the vehicle inspected by your Lexus dealer.
