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 on the side of the
lower part of the rear left seat.
■ Vehicle Proximity Notification System
In the following cases, the Vehicle Proximity Notification Syst em sound may
be difficult for pedestrians, people riding bicycles or other people and vehicles
in the surrounding area to hear:
● When there is a lot of noise in the vicinity
● When it is raining or during strong winds

NOTICE
■Hybrid battery (traction battery) air intake vent
● Do not place objects that will block the air intake vent. When the air intake
vent is blocked, the battery operations will be restricted and cause a
decline in fuel consumption.
● Clean the air intake vent regularly to prevent the hybrid batte ry (traction
battery) from overheating.
● 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, contact your Toyota dealer.
● If “MAINTENANCE REQUIRED FOR TRACTION BATTERY COOLING
PARTS SEE OWNER’S MANUAL” is shown on the multi-information dis -
play, the air intake vent and filter may be clogged. Refer to P . 402 for infor-
mation on how to clean the air intake vent.

■ System maintenance
The vehicle has a maintenance-free type immobilizer system.
■ Conditions affecting operation
Depending on the surrounding environment and conditions, the im mobilizer
system may not operate properly. This may prevent the hybrid sy stem from
starting. ( P. 141)
Immobilizer system
The vehicle’s keys ha ve built-in transponder chips that prevent
the hybrid system from starting if a key has not been previousl y
registered in the vehic le’s on-board computer.

chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughl y
with water.
● Wipe away any water.

●Fold the mirrors before washing the vehicle. Start washing from the front of
the vehicle. Make sure to extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle su rface and
harm your vehicle's paint.
● In certain automatic car washes, the rear spoiler may interfere with machine
operation. This may prevent t he vehicle from being cleaned prop erly or
result in damage to the rear spoiler.
■ High pressure car washes
●Do not allow the nozzles of the car wash to come within close p roximity of
the windows.
● Before using the car wash, check that the fuel filler door on y our vehicle is
closed properly.

If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. In that case, f ollow the fol-
lowing correction procedures to wash the vehicle:
● Place the electronic key in a location 6 ft. (2 m) or more away from the vehi-
cle. (Take care to ensure that the key is not stolen.)
