differ depending on the model/type.

The following gauges, meters and display illuminate when the
“ENGINE START STOP” switch is in IGNITION ON mode.
Speedometer
Displays the vehicle speed.
Voltage gauge
Displays the battery voltage. If the voltage is either too high or too low, the
display will flash.
Shift position and shift range/gear display
Displays the shift position along with the currently selected shift range or
gear. ( P. 120, 122)
Multi-information display

When driving
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indi-
cates the maximum engine speed.
●The following may indicate that the engine is overheating. Immediately stop the
vehicle in a safe place. (
P. 3 9 2 )
• The engine coolant temperature gauge is in the red zone (H)
• The display on the engine oil temperature gauge flashes
■When driving the vehicle
If the display on the voltage gauge starts to flash while the engine is running, it may
indicate that there is a malfunction in the vehicle’s charging system. Have your vehi-
cle inspected by your Lexus dealer.

4-3. Do-it-yourself maintenance
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions.
■When working on the engine compartment:
●Keep hands, clothing, and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator , exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easi ly, such as paper or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
■When working near the electric cooling fan or radiator grille:
Be sure the “ENGINE START STOP” switch is OFF.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fan may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. ( P. 2 9 0 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also a backfire could cause a fire in the engine compartment.

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 already in the
engine.
Make sure to check th e 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.
It takes about 1.6 qt. (1.5 L, 1.3 lmp.qt.) to raise the oil level from low to full on the
dipstick.
■Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy, and good
starting in cold weather.
*: If SAE 5W-30 oil is not avail-able, SAE 10W-30 oil may be
used. However, it should be
replaced with SAE 5W-30 at
the next oil change.

5-2. Steps to take in an emergency
Stop the vehicle immediately.A buzzer sounds and a warning message is shown on the multi-informa-
tion display. The following warnings indicate the possibility of damage to
the vehicle that may lead to an accident. Immediately stop the vehicle in a
safe place and contact your Lexus dealer.
Wa r n i n g m e s s a g eDetails
(Flashing)
Indicates an abnormal engine oil pressure.
The warning light may turn on if the engine oil pres-
sure is too low.
(Flashing)
Indicates that the engine oi l temperature is too high.
The engine oil temperature gauge display will also
flash. ( P. 1 2 8 )

6-1. Specifications
Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity
● The 5W 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 30 in 5W-30 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 condition.
Oil capacity
(drain and refill)
with filter 9.8 qt. (9.3 L, 8.2 lmp.qt.)
without filter8.7 qt. (8.2 L, 7.2 lmp.qt.)
Oil gradeILSAC multi-grade engine oil

viscosity
Use Lexus approved “Toyota Genuine Motor Oil” or
equivalent to satisfy the grade and viscosity shown
below.
