loss of engine power is experienced. (For example, the vehicle speed does not
increase.)

●

“Engine Coolant Temp High Stop in a Safe Place See Owner's Manual” is
shown on the multi-information display.

●

Steam comes out from under the hood.

Stop the vehicle in a safe place and turn off the air conditioning system, and
then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.

If your vehicle overheats

The following may indicate that your vehicle is overheating.

Add coolant if necessary.

Water can be used in an emergency if coolant is unavailable.

Start the engine and turn the air conditioning system on to check that the radi-
ator cooling fans operate and to check for coolant leaks from the radiator or
hoses.

The fans operate when the air conditioning system is turned on immediately after a

cold start. Confirm that the fans are operating by checking the fan sound and air flow.

If it is difficult to check these, turn the air conditioning system on and off repeatedly.

(The fan may not operate in freezing temperatures.)

If the fans are not operating:
Stop the engine immediately and contact your Lexus dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Lexus dealer.

WARNING

■

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.

●

Keep hands and clothing (especially a tie, a scarf or a muffler) away from the fans and

belts. Failure to do so may cause the hands or clothing to be caught, resulting in seri-

ous injury.

●

RC350/RC300 AWD: While the engine

and radiator are hot, do not loosen or remove

the coolant reservoir cap or coolant inlet cap.

(The coolant inlet cap is located under the

engine cover.)

High temperature steam or coolant could

spray out.

●

RC300: While the engine and radiators are

hot, do not loosen or remove the coolant res-

ervoir cap, coolant inlet cap, or intercooler

coolant reservoir cap.

High temperature steam or coolant could

spray out.

●

RC F: While the engine and radiator are hot,

do not loosen or remove the coolant reser-

voir cap.

High temperature steam or coolant could

spray out.

NOTICE

■

When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding cool coolant

to a hot engine too quickly can cause damage to the engine.

■

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.

532

7-2. Steps to take in an emergency

RC F_U

Stop the engine. Set the parking brake and shift the shift lever to P.
Remove the mud, snow or sand from around the rear wheels.
Place wood, stones or some other material under the rear wheels to help pro-
vide traction.
Restart the engine.
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



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 damaging the transmission and other components

●

Avoid spinning the rear 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 (RC350/RC300 AWD)
“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.
