Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the hybrid system and turn the air conditioning system
on to check that the radiator cooling fan operates and to
check for coolant leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on
immediately after a cold start. Confirm that the fan is 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.)

display.
If the message does not disappear:
Stop the hybrid system and contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped
professional.
If the message is not displayed:
Have the vehicle inspected at the nearest any authorized
Lexus dealer or repairer, or another duly qualified and
equipped professional.

When trouble arises
CT200h_OM_OM76067E_(EE)
CAUTION
To prevent an accident or injury when inspecting under the hood of your
vehicle
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, caus-
ing serious injuries such as burns.
Check that the indicator on the “POWER” switch and the “READY” indi-
cator are off.
On hybrid vehicles, the gasoline engine may automatically start, or the
cooling fan may suddenly operate even if the gasoline engine stops. Do
not touch or approach rotating parts such as the fan, which may lead to
fingers or clothing (especially a tie, a scarf or a muffler) getting caught,
resulting in serious injury.
Do not loosen the coolant reservoir cap while the hybrid system and radi-
ator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem 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 commercially available coolant additives.

If the vehicle becomes stuck
CAUTION
When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the sur-
rounding 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 changing the shift position
Be careful not to change the shift position with the accelerator pedal
depressed.
Changing the shift position to any positions other than P or N may cause the
vehicle to accelerate abruptly, causing an accident and resulting in death or
serious injury.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Set the parking brake and shift the shift position to P.
Stop the hybrid system.
Remove the mud, snow or sand from around the stuck
tire.
Place wood, stones or some other material under the tires
to help provide traction.
Restart the hybrid system.
Shift the shift position to D or R, release the parkingSTEP1

CT200h_OM_OM76067E_(EE)Engine oil selection
“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
15W-40 and 20W-50:
API grade SL, SM or SN multigrade engine oil
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 oper-
ated at high speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil contain-
ers to help you select the oil you should use.
API Service Symbol
Top portion: The oil quality des-
ignation by API (American
Petroleum Institute) (SN)
Center portion: The SAE vis-
cosity grade (SAE 0W-20)
Lower portion:
“Resource-Conserving” means
that the oil has fuel saving and
environmental protection capa-
bilities.
ILSAC Certification Mark
The ILSAC (International
Lubricant Standardization and
Approval Committee) Certifica-
tion Mark is displayed on the
front of the container.
