IS200t_EE(OM53D19E)
Start the engine.
To inject the sealant and inflate the
tire, turn the compressor switch on.
Inflate the tire until the specified air
pressure is reached.
The sealant will be injected and the
pressure will surge and then gradu-
ally decrease.
The air pressure gauge will display
the actual tire inflation pressure
about 1 minute (5 minutes at low
temperature) after the switch is
turned on.
Inflate the tire until the specified air
pressure.
• Turn the compressor switch off and
then check the tire inflation pressure.
Being careful not to over inflate,
check and repeat the inflation pro-
cedure until the specified tire infla-
tion pressure is reached.
• If the tire inflation pressure is still lower than the specified point after inflation
for 35 minutes with the switch on, the tire is too damaged to be repaired. Turn
the compressor switch off and contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
• If the tire inflation pressure exceeds the specified air pressure, let out some air
to adjust the tire inflation pressure. ( →P. 5 4 4 , 5 7 2 )12

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 fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately and contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
If the fans are operating:
Have the vehicle inspected at the nearest authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
Check if “Engine Coolant High Temperature” is shown on the multi-informa-
tion display.
If the message does not disappear:
Stop the engine 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 authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.

5689-1. Specifications
IS200t_EE(OM53D19E)
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 viscosit y 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 labels:
Either or both API registered marks are added to some oil containers to help
you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designation by
American Petroleum Institute (API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-Conserv-
ing” means that the oil has fuel-saving
and environmental protection capa-
bilities.
ILSAC Certification Mark
The International Lubricant Specifi-
cation Advisory Committee (ILSAC)
Certification Mark is displayed on
the front of the container.
