■Engine oil consumption
A certain amount of engine oil will be con-
sumed while driving. In the following situa-
tions, oil consumption may increase, and 
engine oil may need to be refilled in 
between oil maintenance intervals.
●When the engine is new, for example 
directly after purchasing the vehicle or 
after replacing the engine
●If low quality oil or oil of an inappropriate 
viscosity is used
●When driving at high engine speeds or 
with a heavy load, or when driving while 
accelerating or decelerating frequently
●When leaving the engine idling for a long  time, or when driving frequently through 
heavy traffic
■After changing the engine oil (LC500h)

WARNING
■Used engine oil
●Used engine oil contains potentially 
harmful contaminants which may 
cause skin disorders such as inflamma-
tion and skin cancer, so care should be 
taken to avoid prolonged and 
repeated contact. To remove used 
engine oil from your skin, wash thor-
oughly with soap and water.
●Dispose of used oil and filters only in a 
safe and acceptable manner. Do not 
dispose of used oil and filters in house-
hold trash, in sewers or onto the 
ground. 
Call your Lexus dealer, service station 
or auto parts store for information 
concerning recycling or disposal.

WARNING
●Do not leave used engine oil within the 
reach of children.
NOTICE

Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on the 
vehicle components.
●Avoid overfilling, or the engine could

WARNING
■When installing the tire
Failure to follow these precautions could 
cause the wheel nuts to loosen and the 
tire to fall off, resulting in death or serious 
injury.
●Never use oil or grease on the wheel 
bolts or wheel nuts. 
Oil and grease may cause the wheel 
nuts to be excessively tightened, lead-
ing to bolt or disc wheel damage. In 
addition, the oil or grease can cause 
the wheel nuts to loosen and the wheel 
may fall off, causing a serious accident. 
Remove any oil or grease from the 
wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a 
torque wrench to 103.3 ft•lbf (140 
N•m, 14.3 kgf•m) soon as possible 
after changing wheels.
●Do not attach a heavily damaged 
wheel ornament, as it may fly off the 
wheel while the vehicle is moving.
●When installing a tire, only use wheel 
nuts that have been specifically 
designed for that wheel.
●If there are any cracks or deformations 
in the bolt screws, nut threads or bolt 
holes of the wheel, have the vehicle 
inspected by your  Lexus dealer.
■After using the tools
Before driving, make sure all the tools are 
stored securely in place. Failure to do so 
may cause injury in case of a collision or 
sudden braking.
