■The meters and display illumi-
nate when
The engine switch is in ON.
■Outside temperature display
●In the following si tuations, the cor-
rect outside tempe rature may not
be displayed, or the display may
take longer than normal to
change:
• When stopped, or driving at low
speeds (less than 12 mph [20
km/h])
• When the outside temperature
has changed suddenly (at the
entrance/exit of a garage, tunnel,
etc.)
●When “--” or “E” is displayed, the
system may be malfunctioning.
Take your vehicle to your Toyota
dealer.
■Liquid crystal display
Small spots or light spots may
appear on the display. This phenom-
enon is characteristi c of liquid crys-
tal displays, and there is no problem
continuing to use the display.
■Customization
The meters can be customized on of the multi-information display.
(  P.94)
■Display items
 Odometer
Displays the total distance the vehi-
cle has been driven.
 Trip meter A/trip meter B
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 independently.
Distance until next engine oil
change
Displays the distance the vehicle
can be driven until an oil change is
WARNING
■The information display at
low temperatures
Allow the interior of the vehicle to
warm up before u sing the liquid
crystal informat ion display. At
extremely low temperatures, the
information display monitor may
respond slowly, and display
changes may be delayed.
For example, there is a lag
between the driver’s shifting and
the new gear number appearing
on the display. This lag could
cause the driver to downshift
again, causing rapid and exces-
sive engine braking and possibly
an accident resulting in death or
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 maxi-
mum engine speed.
●The engine may be overheating
if the engine coolant tempera-
ture gauge is in the red zone
(H). In this case, immediately
stop the vehicle in a safe place,
and check the engine after it
has cooled completely.

■To prevent damage to exter-
nal devices
●Do not leave external devices in
the vehicle. The temperature
inside the vehicle may become
high, resulting in damage to an
external device.
●Do not push down on or apply
unnecessary force to an exter-
nal device or the cable of an
external device while it is con-
nected.
■To prevent battery discharge

■The wireless charger can be
operated when
The engine switch is in ACC or ON.
■Portable devices that can be
charged
●Portable devices compatible with
the Qi wireless charging standard
can be charged by the wireless
charger. However, compatibility
with all devices which meet the Qi
wireless charging standard is not
guaranteed.
●The wireless charger is designed
to supply low power electricity (5
W or less) to a cellular phone,
smartphone, or other portable
device.
●Failure to do so may result in the
possibility of fire, However, porta- ble devices, such as the following,
can be charged with more than 5
W.
• 7.5 W charging compatible iPhones can be charged at 7.5 W
or less.
• Portable devices which conform to WPC Ver 1.2.4 (Extended Power
profile ) can be charged at 10 W or
less.
■If a cover or accessory is
attached to the portable device
Do not charge a portable device if a
cover or accessory w hich is not Qi
compatible is atta ched. Depending
on the type of cover (including for
certain genuine manufacturer parts)
and/or accessory a ttached, it may
not be possible to charge the porta-
ble device. If the portable device is

WARNING
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.
ItemsParts and tools●Be careful not to touch the
engine, radiator, exhaust mani-
fold, etc. right a fter 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 and
rags, in the engine compart-
ment.
●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 con-
tains poisonous and corrosive
sulfuric acid.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the engine switch is off.
With the engine switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.390)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
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.

■Oil capacity (Drain and
refillreference
*)
*: The engine oil capacity is a refer-
ence quantity to be used when
changing the engine oil. 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 Toyota vehicle. Use
Toyota approved “Toyota Genu-
ine Motor Oil” or equivalent to
satisfy the following grade and
viscosity.
Oil grade: ILSAC GF-6A multi-
grade engine oil
Recommended viscosity: SAE
0W-20 Outside temperature
SAE 0W-20 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
Oil viscosity (0W-20 is explained
here as an example):
• The 0W in 0W-20 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 20 in 0W-20 indicates the viscosity characteristic of the
oil when the oil is at high tem-
perature. An oil with a higher
viscosity (one with a higher
value) may be better suited if
Octane Rating87 (Research Octane Number 91) or
higher

Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law. Warning: The temperature grades
of a tire assume tha
t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.

The maximum cold inf lated pressure to
which a tire may be inflated, shown on the
sidewall of the tire

Accessory weight
The combined weight (in excess of those
standard items which may be replaced) of

seats, radio and heater, to the extent that
these items are available as fac-
tory-installed equipment (whether installed
or not)
