For safety and security
■Sounds and vibrations sp ecific to a hybrid vehicle
There may be no engine sound or vibration even though the vehic le is able to
move with the “READY” indicator is illuminated. For safety, app ly the parking
brake and make sure to shift the shift position to P when parke d.
The following sounds or vibrations may occur when the hybrid sy stem is
operating and are not a malfunction:
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) under the
rear seats when the hybrid system starts or stops.
● Relay operating sounds such as a snap or soft clank will be emi tted from the
hybrid battery (traction battery), under the rear seats, when the hybrid sys-
tem is started or stopped.
● Sounds from the hybrid system may be heard when the back door is open.
● Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is
depressed or as the accelerator pedal is released.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent. ( P. 89)
■ Vehicle proximity notification system
In the following cases, the vehicle proximity notification syst em may be diffi-
cult for surrounding people to hear.
● In very noisy areas
● In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of
the vehicle, it may be more difficult to hear from the rear of the vehicle com-
pared to the front.
■ When “Proximity Notification Syst em Malfunction Visit Your Dealer” is
displayed on the multi-information display
The vehicle proximity notification system may be malfunctioning . Have the
vehicle inspected by your Toyota dealer immediately.
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recyc ling and dis-
posal. Do not dispose of the vehicle yourself.

For safety and security
There is an air intake vent under
the right side of the rear seat for
the purpose of cooling the hybrid
battery (traction battery). If the
vent is blocked, charging/dis-
charging of the hybrid battery
(traction battery) may become lim-
ited.
When a certain level of impact is detected by the impact sensor , the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the ri sk of electrocution and fuel leakage. If
the emergency shut off system activates, your vehicle will not restart.
To restart the hybrid system , contact your Toyota dealer.
A message is automatically displ ayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions.

■If a warning light comes on, a warning message is displayed, or the
12-volt battery is disconnected
The hybrid system may not start. In this case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dea ler.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cann ot be started,
refuel the vehicle with at least enough gasoline to make the lo w fuel level
warning light ( P. 594) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
2.0 gal. [7.5 L, 1.7 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when th e vehicle is
inclined.)
■ Electromagnetic waves
●High voltage parts and cables on hybrid vehicles incorporate el ectromag-
netic shielding, and therefore emit approximately the same amount of elec-
tromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-p roduced
radio parts.
■ Hybrid battery ( traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.
■ Starting the hybrid system in a n extremely cold environment
When the hybrid battery (traction battery) is extremely cold (b elow approxi-
mately -22°F [-30°C]) under the influence of the outside temper ature, it may
not be possible to start the hybrid system. In this case, try to start the hybrid
system again after the temperature of the hybrid battery increases due to the
outside temperature increase etc.

NOTICE
■Hybrid battery (traction battery) air intake vent
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. If the vent is blocked, the charging/dis-
charging of the hybrid battery (traction battery) may become li mited.
● When dust etc. has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not get water or foreign materials in the air intake vent as this may
cause a short circuit and damage the hybrid battery (traction b attery).
● Do not carry large amounts of water such as water cooler bottle s in the
vehicle. If water spills onto the hybrid battery (traction batt ery), the battery
may be damaged. Have the vehicle inspected by your Toyota deale r.
● There is a filter installed to the air intake vent. When the fi lter remains
noticeably dirty even after cleaning the air intake vent, filte r cleaning or
replacement is recommended. For information regarding filter cl eaning or
replacement, refer to P. 551.
● If “Maintenance required for Traction battery 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. 551 for information on how to clean the
air intake vent.
