■

If “Hybrid System Overheated Reduced Output Power” is shown on the
multi-information display

Stop the vehicle in a safe place.
Stop the hybrid system and carefully lift the hood.
After the hybrid system has
cooled down, inspect the hoses
and radiator core (radiator) for
any leaks.

Radiator
Cooling fans

If a large amount of coolant leaks,

immediately contact your Lexus

dealer.

The coolant level is satisfactory if
it is between the “FULL” and
“LOW” lines on the reservoir.

Reservoir
“FULL” line

Add coolant if necessary.

Water can be used in an emergency

if coolant is unavailable.

RX450h_RX450hL_U

Start the hybrid system and check if “Hybrid System Overheated Reduced
Output Power” is shown on the multi-information display.
If the message does not disappear:
Stop the hybrid system and contact your Lexus dealer.
If the message is not displayed:
Have the vehicle inspected at the nearest Lexus dealer.

WARNING

■

To prevent an accident or injury when inspecting under the hood of your vehicle
Observe the following precautions.

Failure to do so may result in serious injury such as burns.

●

If steam is seen coming from under the hood, do not open the hood until the steam

has subsided. The engine compartment may be very hot.

●

After the hybrid system has been turned off, check that the “READY” indicator is off.

When the hybrid system is operating, the gasoline engine may automatically start, or

the cooling fans may suddenly operate even if the gasoline engine stops. Do not

touch or approach rotating parts such as the fans, which may lead to fingers or cloth-

ing (especially a tie, a scarf or a muffler) getting caught, resulting in serious injury.

●

Do not loosen the radiator cap and the coolant reservoir caps while the hybrid system

and radiator are hot.

High temperature steam or coolant could spray out.

NOTICE

■

When adding engine/power control unit coolant
Add coolant slowly after the hybrid system has cooled down sufficiently. Adding cool

coolant to a hot hybrid system too quickly can cause damage to the hybrid system.

■

To prevent damage to the cooling system
Observe the following precautions:

●

Avoid contaminating the coolant with foreign matter (such as sand or dust etc.).

●

Do not use any coolant additive.

706

8-2. Steps to take in an emergency

RX450h_RX450hL_U

Stop the hybrid system. Shift the shift lever to P and set the parking brake.
Remove the mud, snow or sand from around the front wheels.
Place wood, stones or some other material under the front wheels to help pro-
vide traction.
Restart the hybrid system.
Shift the shift lever to D or R and release the parking brake. Then, while exer-
cising caution, depress the accelerator pedal.

■

When it is difficult to free the vehicle

If the vehicle becomes stuck

Carry out the following procedures if the tires spin or the vehicle becomes
stuck in mud, dirt or snow:

Press

to turn off TRAC.

WARNING

■

When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the surrounding

area is clear to avoid striking other vehicles, objects or people. The vehicle may also

lunge forward or lunge back suddenly as it becomes free. Use extreme caution.

■

When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.

This may lead to unexpected rapid acceleration of the vehicle that may cause an acci-

dent resulting in death or serious injury.

NOTICE

■

To avoid damage to the hybrid transmission and other components

●

Avoid spinning the front wheels and depressing the accelerator pedal more than nec-

essary.

●

If the vehicle remains stuck even after these procedures are performed, the vehicle

may require towing to be freed.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However, it
must be replaced with SAE 0W-20
at the next oil change.

Oil viscosity (0W-20 is explained here as an example):

• The 0W in 0W-20 indicates the characteristic of the oil which allows cold

startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.

• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the

oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.

How to read oil container label:
The International Lubricant Specifi-
cation Advisory Committee
(ILSAC) Certification Mark is added
to some oil containers to help you
select the oil you should use.
