Gauges and meters
The units used on the speedometer, tachometer gauge display and
multi-information 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 display 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 inde-
pendently.

When driving

Changing units for the digital speedometer (right-hand drive vehicles only)
Units for the digital speedometer can be changed between km/h and mph by
pushing and holding the odometer/trip meter reset button while the odome-
ter is displayed. At this time, all the units for the multi-information display
will also change.
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
indicates the maximum engine speed.
The following may indicate that the engine is overheating. Immediately
stop the vehicle in a safe place. (P. 465)
• The display on the engine coolant temperature gauge flashes
• The display on the engine oil temperature gauge flashes

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropriate
to the prevailing weather conditions.
Pre-winter preparations
Use fluids that are appropriate to the prevailing outside
temperatures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician inspect the level and specific
gravity of battery electrolyte.
Have the vehicle fitted with four snow tires.
Ensure that all tires are the specified size and the same brand.
Tire chains cannot be installed on 19-inch tires. Use the
specified type of tire chains and install them on the rear
tires only. Before installing the tire chains, change all four
tires and wheels to those of the specified size (tires: 225/
40R18, wheels: 18x8JJ +45 offset). For details, contact any
authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.
Before driving the vehicle
Perform the following according to the driving conditions.
Do not try to forcibly open a window or move a wiper that
is frozen. Pour warm water over the frozen area to melt the
ice. Wipe away the water immediately to prevent it from
freezing.
To ensure proper operation of the climate control system
fan, remove any snow that has accumulated on the air inlet
vents in front of the windshield.
Remove any ice that has accumulated on the vehicle chas-
sis

Maintenance and care
IS F_EE
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, 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 driving 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.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
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. 374)
CAUTION
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in the eyes.

Engine oil
With 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.
Holding a rag under the end, pull the dipstick out and check
the oil level.

6-1. Specifications
IS F_EERecommended viscosity (SAE):
SAE 5W-30 is filled into your
Lexus vehicle at manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures,
the engine may become diffi-
cult to start, so SAE 5W-30
engine oil is recommended.
Oil viscosity (5W-30 is explained here as an example):
• The 5W in 5W-30 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 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 oper-
ated at high speeds, or under extreme load conditions.
Preferred
Temperature range anticipated
before next oil change.
