■Warning message in radar cruise mode (if equipped)
In the following cases, the warning message may not be displayed even if vehicle-to-vehi-
cle distance decreases:
●When your vehicle and the vehicle ahead are traveling at the same speed or the vehicle
ahead is traveling more quickly than your vehicle
●When the vehicle ahead is traveling at a very low speed
●Immediately after cruise control speed is set
●At the instant the accelerator pedal is depressed
■Open door warning message
The open door warning message continues to display until a door or the trunk is fully
closed, even if the power switch is turned off. However, approximately 20 minutes after a
door or the trunk is not fully closed, the 12-volt battery-saving function operates and the
display turns off even though a door or the trunk is not fully closed.
■Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an audio sound.

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 hybrid system 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 any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.

Vehicle specifications
GS450h_300h_OM_OM30F00E_(EE)
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 Specificatio n Advisory Committee (ILSAC) Certifica-
tion Mark is displayed on the front of the container.
