Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
After installing the support rod into the slot
Make sure the rod supports the hood securely from falling down on to your
head or body.
NOTICE
When closing the hood
Be sure to return the support rod to its clip before closing the hood. Closing the

Maintenance and care
Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as that
already in the engine.
Make sure to check the oil type and prepare the items needed before
adding oil.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.
Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following
situations, 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

fied and equipped professional, service station or auto parts store for informa-
tion concerning recycling or disposal.
Do not leave used engine oil within the reach of children.

Maintenance and care
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the hybrid system is cold.
Engine coolant reservoir
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line. (P. 628)
Power control unit coolant reservoir
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line. (P. 628)
Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35C [-31F])
For more details about coolant, contact any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine/power control unit coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for leaks
in the cooling system.

When the hybrid system is hot
Do not remove the engine/power control unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the cap
is removed, causing serious injuries, such as burns.
NOTICE
When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion pro-
tection and cooling. Be sure to read the antifreeze or coolant label.
If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
Radiator and condenser
WA R N I N G
When the hybrid system is hot
Do not touch the radiator or condenser as they may be hot and cause serious
injuries, such as burns.
When the electric cooling fans are operating
Do not touch the engine compartment.
The electric cooling fans may keep rotating for about 3 minutes even after the
power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature is
high. Be sure the power switch is off when working near the electric cooling
fans or radiator grille.
