Checking and replacing fuses
WARNING
Observe the following precautions. Failure to do so may cause damage to the vehicle,
possibly leading to a fire or injury.
●
Never use a fuse of a higher amperage rating than specified, or use any other object in
place of a fuse.
●
Always use a genuine Lexus fuse or equivalent. Never replace a fuse with a wire, even
as a temporary fix.
●
Do not modify the fuses or fuse boxes.
●
Never check or replace the fuses in the fuse box near the inverter with converter
assembly, as there are high voltage parts and wiring near the fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
NOTICE
Have the cause of electrical overload determined and repaired by your Lexus dealer as
soon as possible.

"Toyota Genuine Motor Oil" is used in your Lexus vehicle. Use Lexus approved
"Toyota Genuine Motor Oil" or equivalent to satisfy the following grade and
viscosity.
Oil grade: ILSAC GF-6B multigrade engine oil
Recommended viscosity: SAE 0W-16
A
Outside temperature
SAE 0W-16 is the best choise for good fuel economy and good starting in cold
wheather. If SAE 0W-16 is not available, SAE 0W-20 oil may be used. However, it
must be replaced with SAE 0W-16 at the next oil change.
■
How to read oil container label
API registered mark is added to some oil con-
tainers to help you select the oil you should use.
Oil viscosity (0W-16 is explained here as an ex-
ample):
●
The 0W in 0W-16 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 16 in 0W-16 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 conditions.
Cooling system
*1 :
The engine oil capacity is a reference quantity to be used when changing the engine
oil. Warm up the engine and turn off the hybrid system, wait more than 5 minutes, and
check the oil level on the dipstick.
