ator cooling fans operate and to check for coolant leaks from the radiator or
hoses.

(The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately an d contact your Lexus dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Lexus dealer.

ual” is shown on the multi-information display.
If the message does not disappear:

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 h ood, 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.
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 foreig n matter (such as sand or dust etc.).
●Do not use any coolant additive.
●IS350 AWD/IS350/IS300 AWD: Do notloosen the coolant inlet cap or coolant reser-
voir cap while the engine and radiator are hot.

High temperature steam or coolant could
spray out.
●IS300: Do not loosen the coolant inlet cap,
coolant reservoir cap, or intercooler reser-
voir cap while the engine and radiator are hot.

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.

This may lead to unexpected rapid acceleration of the vehicle that may cause an acci-
dent resulting in death or serious injury.
NOTICE

●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.
