Plug-in hybrid system
There is an air intake vent under
the rear seat for cooling the DC/DC
converter.
Blocking the air intake vent may
prevent the plug-in hybrid system
from operating properly.
When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks
off the high voltage current and
NOTICE
■Notice about fuel
●For Plug-in Hybrid Electric Vehi-
cles, fuel may remain in the tank for a long time and undergo changes in quality depending on the how the
vehicle is used. Refuel at least 20 L (5.3 gal., 4.4 Imp.gal.) of fuel every 12 months (refuel a total of at least
20 L [5.3 gal., 4.4 Imp.gal.] over a 12-month period), as this may affect components of the fuel sys-
tem or the gasoline engine.
●If the vehicle has not been refueled
for a certain amount of time and it is possible that the quality of the fuel remaining in the tank has changed,
“No New Fuel has been Added Recently Please refuel” is displayed on the multi-information display
when the power switch is turned to ON. If the message is displayed, refuel the vehicle immediately.
DC/DC converter air intake
vent
NOTICE
■DC/DC converter air intake vent
●Make sure not to block the air
intake vent with anything, such as a seat cover, plastic cover, or lug-gage. Blocking the air intake vent
may prevent the plug-in hybrid sys- tem from operating properly.
●When dust etc. has accumulated in the air intake vent, clean it with a vacuum cleaner to prevent the vent
from clogging.
●Do not wet or allow foreign sub-
stances to enter the air vent as this may cause a short circuit and dam-age the DC/DC converter.
●Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the DC/DC converter, the converter may be damaged. Have the vehicle
inspected by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●A filter is installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filter cleaning or replacement is recommended.
When cleaning the filter, refer to P.504.
●If “Maintenance required for DCDC converter cooling parts See Owner’s Manual” is shown on the
multi-information display, the air intake vent and filter may be clogged. Refer to P.504 for informa-
tion on how to clean the air intake vent.

Maintenance and care
WARNING
■When working on the engine compartment
●Make sure that “IGNITION ON” on the multi-information display and the “READY” indicator are both off.
●Keep hands, clothing and tools away from the moving fan.
●Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other flu-ids may also be hot.
●Do not leave anything that may burn easily, such as paper and
rags, in the engine compartment.
●Do not smoke, cause sparks or
expose an open flame to fuel. Fuel fumes are flammable.
●Take care because brake fluid can harm your hands or eyes and dam-age 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, consult a doctor.
■When working near the electric
cooling fan or radiator grille
Be sure the power switch is off. With the power switch in ON, the
electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is
high. ( P.482)
■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 fil-ter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill- ing, it may indicate a serious problem.

5468-2. Steps to take in an emergency
shown on the multi-information dis-
play, the vehicle may have run out of fuel. Stop the vehicle in a safe place and, if the fuel level is low, refuel the
vehicle. • “Hybrid System Stopped”• “Engine Stopped”
●If “Maintenance required for DCDC converter cooling parts See Owner’s
Manual” is shown, the filter may be clogged, the air intake vent may be blocked, or there may be a gap in the
duct. Therefore, perform the following correction procedure.• If the air intake vent or filter of the
DC/DC converter are dirty, perform the procedures on P.504 to clean them.
• If the warning message is shown when the air intake vent and filter of the DC/DC converter are not dirty,
have the vehicle inspected at any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
●If “12-Volt Battery Charging System
Malfunction Stop in a Safe Place See Owner’s Manual” is shown
Indicates a malfunction in the vehicle’s
charging system. Pull over and stop the
vehicle as soon as it is safe to do so.
While the message is displayed, the
functions of the air conditioning, etc.
may be partially limited in order to
reduce the power consumption of the
12-volt battery.
■If “Hybrid System Overheated Out- put Power Reduced” is shown
The message may be shown when driv- ing under severe operating conditions. (For example, when driving up a long
steep hill or driving up a steep hill in reverse.)
Coping method: P.578
■If “Traction Battery Needs to be
Protected Refrain from the Use of N Position” is shown
This message may be displayed when
the shift lever is in N.
As the hybrid battery (traction battery) cannot be charged when the shift lever is in N, shift the shift lever to P when the
vehicle is stopped.
■If “Traction Battery Needs to be Protected Shift into P to Restart” is shown
This message is displayed when the hybrid battery (traction battery) charge has become extremely low because the
shift lever has been left in N for a certain amount of time.
When operating the vehicle, shift to P
and restart the hybrid system.
■If “Shift to P Before Exiting Vehi- cle” is shown
Message is displayed when the driver’s
door is opened without turning the power switch to OFF with the shift lever in any position other than P.
Shift the shift lever to P.
■If “Shift Out of N Release Accelera- tor Before Shifting” is shown
Message is displayed when the acceler-
ator pedal has been depressed and the shift lever is in N. Release the accelera-tor pedal and shift the shift lever to D or
R.
■If “Press Brake when vehicle is stopped Hybrid system may over-heat” is shown
Message is displayed when the acceler- ator pedal is depressed to maintain the vehicle position when stopped on a
upward slope, etc.
If this continues, the hybrid system may overheat.
Release the accelerator pedal and depress the brake pedal.
■If “Auto Power OFF to Conserve Battery” is shown
Power was turned off due to the auto- matic power off function.
Next time when starting the hybrid sys-
tem, operate the hybrid system for approximately 5 minutes to recharge the

■Oil capacity (Drain and refill  reference*)
*: The engine oil capacity is a reference quantity to be used when changing the
engine oil. Warm up the engine and turn off the hybrid system, 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. Toyota rec-
ommends the use of approved
“Toyota Genuine Motor Oil”.
Another motor oil of matching qual-
ity can also be used.
Oil grade:
0W-16:
API grade SN “Resource-Conserv-
ing”, SN PLUS “Resource-Conserv-
ing” or SP “Resource-Conserving”;
or ILSAC GF-6B multigrade engine
oil
0W-20 and 5W-30:
API grade SM “Energy-Conserv-
ing”, SN “Resource-Conserving”,
SN PLUS “Resource-Conserving”
or SP “Resource-Conserving”; or
ILSAC GF-6A multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-16 is filled into your
Toyota vehicle at manufacturing,
and the best choice for good fuel economy and good starting in cold
weather.
If SAE 0W-16 oil is not available,
SAE 0W-20 oil may be used. How-
ever, it should be replaced with
SAE 0W-16 at the next oil change.
Temperature range anticipated
before next oil change
Preferred
Oil viscosity (0W-16 is explained
here as an example):
• The 0W in 0W-16 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
