ing the wheels, underside of the vehicle, etc.

■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused  by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer  check the following:
●Brake function
●Changes in quantity and quality of engine  oil, transaxle fluid for the hybrid system
etc.
●Lubricant condition for the bearings and suspension joints (where possible), and
the function of all joints, bearings, etc.
As flooding may damage components involv ed in P position control, the parking
lock may jam in the locked position.
■If the vehicle will not shift out of the P position
There is a possibility that the 12-volt batt ery is discharged. Check the 12-volt battery
in this situation.

Vehicle specifications
■Engine oil selection
“Toyota Genuine Motor Oil” is used  in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or  equivalent to satisfy the follow-
ing grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced with
SAE 0W-20 at the next oil
change.
The 0W portion of the oil viscosity rating  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 oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the vehicle
is operated at high speeds, or  under extreme load conditions.
How to read oil container label:
The ILSAC (International Lubricant St andardization and Approval Com-
mittee) Certification Mark is added to  some oil containers to help you
select the oil you should use.
