Gauges and meters
The units used on the speedometer and the tachometer gauge display may
differ depending on the model/type.

The following gauges, meters and display illuminate when the
“ENGINE START STOP” switch is in IGNITION ON mode.Engine coolant temperature gauge
Displays the engine coolant temperature. If the temperature is too high,
the display will flash.
Engine oil temperature gauge
Displays the engine oil temperature. If the temperature is too high, the dis-
play will flash.
Odometer and trip meter
Odometer: Displays the total distance the vehicle has been driven.
Trip meter: Displays the distance the vehicle has been driven since the meter was last reset. Trip meters “A” and “B” can be
used to record and display different distances indepen-
dently.

When driving
IS F_U
CAUTION
■When the temperature of the display is extremely low
Allow the interior of the vehicle to warm up before using the shift position and shift
range/gear display. At extremely low temperatures, the display may respond slowly,
and display changes may be delayed.
For example, there is a lag between the driver’s downshifting and the new gear
number appearing on the display. In this case, wait until the display changes and
take care not to downshift again, causing rapid and excessive engine braking and
possibly an accident resulting in death or serious injury.
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. 505)
• The display on the engine coolant temperature gauge flashes
• The display on the engine oil temperature gauge flashes

4-3. Do-it-yourself maintenance
IS F_U
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 easily, 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. 4 0 4 )
■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.

Engine oilWith the engine at operating temperature and turned off, check the oil
level on the dipstick.
■ Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than five minutes for the oil to drain
back into the bottom of the engine.
Hold a rag under the end and pull
the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.

Lubrication system
*: The engine oil capacity is a reference quantity to be used when exchanging.
Warm up and turn off the engine, wait more than 5 minutes, and check the oil
level on the dipstick.
■ 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 5W-30
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 5W-30 is not available,
SAE 10W-30 oil may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.

Vehicle specifications
IS F_U
Oil viscosity (5W-30 is explained here as an example):
• The 5W in 5W-30 indicates the characteristic of the oil which allows coldstartability. 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 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.
How to read oil container label:
The ILSAC (International Lubricant Standardization and Approval Com-
mittee) Certification Mark is added to some oil containers to help you
select the oil you should use.
Cooling system
Capacity12.6 qt. (11.9 L, 10.5 Imp. qt.)
Coolant type
Use either of the following.
• “Toyota Super Long Life Coolant”
• Similar high-quality ethylene glycol-based non-sili-cate, non-amine, non-nitrite, and non-borate cool-
ant with long-life hybrid organic acid technology
Do not use plain water alone.
