GS350/250_EE (OM30C36E)
If your vehicle overheats
Stop the vehicle in a safe place and turn off the air conditioning
system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam subsides
and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the instru-
ment panel) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call any authorized Lexus
dealer or repairer, or another duly qualified and equipped profes-
sional.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.
If the engine compartment cover
needs to be removed: P. 6 6 1

When trouble arises
GS350/250_EE (OM30C36E)Add engine coolant if neces-
sary.
Water can be used in an emergency
if engine coolant is unavailable.
(P. 847)
Have the vehicle inspected at the nearest authorized Lexus dealer
or repairer, or another duly qualified and equipped professional as
soon as possible.
Overheating
If you observe the following, your vehicle may be overheating:
The engine coolant temperature gauge enters the red zone or a loss of power
is experienced.
Steam comes out from under the hood.

CAUTION
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 away from the fans, etc. while the engine is oper-
ating.
Do not loosen the radiator cap while the
engine and radiator are hot.
High temperature steam or coolant
could spray out.

GS350/250_EE (OM30C36E)
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 commercially available coolant additives.

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 provide traction.
Restart the engine.
Shift the shift lever to D or R and release the parking brake.
Then, while exercising caution, depress the accelerator pedal.

*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. Warm up and turn off the engine, wait more than 5 minutes,
and check the oil level on the dipstick.
Engine oil selection (GS250)
EU area, Nordic countries, Russia, Ukraine, Croatia, Macedo-

“Toyota Genuine Motor Oil” is used in your Lexus vehicle.
Lexus recommends the use of approved “Toyota Genuine Motor
Oil”. Another motor oil of matching quality can also be used.
Oil grade:
0W-20, 5W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving”,
SN “Resource-Conserving” or ILSAC multigrade engine oil

GS350/250_EE (OM30C36E)Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Lexus vehicle at manufactur-
ing, and the best choice for
good fuel economy, and good
starting in cold weather.
If SAE 0W-20 oil is not avail-
able, SAE 5W-30 oil may be
used. However, it should be
replaced with SAE 0W-20 at
the next oil change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures,
the engine may become diffi-
cult to start, so SAE 5W-30 or
lower viscosity engine oil is
recommended.
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 con-
ditions.
Temperature range anticipated
before next oil change.Preferred
