2-1. Electric vehicle system
■Charging the traction battery
Be sure to maintain the traction battery charge level suitable for your driving needs.
If the traction battery fully discharges, the vehicle cannot be driven at all. When the battery becomes low, charge it as
soon as possible.
■If the traction battery becomes low
●If the traction battery becomes low,
the traction battery charge warning light comes on or flashes and a mes-sage will be displayed on the multi-
information display. ( P.517)
●If the traction battery is completely
discharged, the EV system cannot be started and driving will not be possi-ble. When the traction battery
becomes low, charge it as soon as possible.
■Sounds and vibrations specific to an battery electric vehicle
Because there is no engine sound or vibration, it is easy to mistake the bat-tery electric vehicle for being off when it
is actually still running, as indicated by the “READY” indicator being illuminated. For safety, make sure to always shift the
shift position to P and apply the parking brake when parked.
Before and after the EV system is
started, the following sounds and vibra- tions may occur. However, these sounds and/or vibrations are not signs of mal-
functions:
●The brake system operation sound
may be heard from the front of the vehicle when the driver’s door is opened.
●Motor sounds may be heard from the motor compartment or luggage com-
partment.
●Electrical relay sounds may be heard
from the motor compartment when the EV system starts or stops.
●Relay operating sounds such as a snap or soft clank will be emitted from the traction battery in the following sit-
uations:
• When the EV system is started or stopped• When charging starts or completes
• When the vehicle is driven the first time after the traction battery has been charged using DC charging
●Sounds may be heard due to regener-ative braking when the brake pedal is
depressed or as the accelerator pedal is released.
●Cooling fan operating sounds from the radiator.
●The operation sound of the air condi-tioning system (air conditioning com-pressor, blower motor).
■Maintenance, repair, recycling, and
disposal
Contact any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer regarding maintenance, repair, recycling and disposal. Do not dispose of the vehicle yourself.
A sound which changes in accor-
dance with the driving speed, will
be played in order to warn people
nearby of the vehicle’s approach.
This sound may be heard inside the
vehicle. The sound will stop when
the vehicle speed exceeds approxi-
mately 25 km/h (15 mph).
■Acoustic Vehicle Alerting System
In the following cases, the Acoustic Vehicle Alerting System may be difficult
for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the Acoustic Vehicle Alerting
System is installed on the front of the

■Tire information
●Increase the tire inflation pressure to
20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater than the recommended value when towing. ( P.559)
●Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the val- ues recommended by the manufac-turer of your trailer.
■Trailer lights
Please consult any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer when installing
trailer lights, as incorrect installation may cause damage to the vehicle’s lights. Please take care to comply with
your state’s laws when installing trailer lights.
■Break-in schedule
Toyota recommends that vehicles fitted with new power train components should not be used for towing trailers for
the first 800 km (500 miles).
■Safety checks before towing
●Check that the maximum load limit for
the towing hitch/bracket hitch ball is not exceeded. Bear in mind that the coupling weight of the trailer will add
to the load exerted on the vehicle. Also make sure that you will not be towing a load that exceeds the maxi-
mum permissible axle capacity.
●Ensure that the trailer load is secure.
●Supplementary outside rear view mir- rors should be added to the vehicle if
the traffic behind cannot be clearly seen with standard mirrors. Adjust the extending arms of these mirrors on
both sides of the vehicle so that they always provide maximum visibility of the road behind.
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight bur- den placed on the vehicle compared to normal driving.
●Retighten all bolts securing the hitch-ing ball and bracket after towing for
approximately 1000 km (600 miles).
■If trailer sway occurs
One or more factors (crosswinds, pass- ing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.• Begin releasing the accelerator pedal
immediately but very gradually to reduce speed.
Do not increase speed. Do not apply
vehicle brakes.

NOTICE
■Inspection after off-road driving
●Sand and mud that has accumu-
lated around brake discs may affect braking efficiency and may damage brake system components.
●Always perform a maintenance inspection after each day of off-road
driving that has taken you through rough terrain, sand, mud, or water.

7-1. Maintenance and care
7-1.Mainte nance a nd care
Working from top to bottom, lib-
erally apply water to the vehicle
body, wheel wells and underside
of the vehicle to remove any dirt
and dust.
 Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
 For hard-to-remove marks, use
car wash soap and rinse thor-
oughly with water.
 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean sur-
face, apply wax when the vehicle body
is cool.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface scratches caused in a car wash, etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the
plant.
●The restoration time differs depending
on the depth of the scratch and out- side temperature. The restoration time may become shorter when the coating
is warmed by applying warm water.
●Deep scratches caused by keys,
coins, etc., cannot be restored.
●Do not use wax that contain abra- sives.
■Automatic car washes
●Before washing the vehicle:• Fold the mirrors
• Turn off the power back door (if equipped)
Start washing from the front of the vehi-
cle. Extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle sur-face, parts (wheel, etc.) and harm
your vehicle’s paint.
●Rear spoiler (if equipped) may not be
washable in some automatic car washes. There may also be an increased risk of damage to vehicle.
●When the shift position needs to be held in N, refer to P.251.
■High pressure car washes
As water may enter the cabin, do not bring the nozzle tip near the gaps around the doors or perimeter of the
windows, or spray these areas continu- ously.
■Note for a smart entry & start sys-tem
●If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the following correction procedures to
wash the vehicle: • Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-sav- ing mode to disable the smart entry & start system ( P.204)
●If the electronic key is inside the vehi- cle and a door handle becomes wet
during a car wash, a buzzer may sound outside the vehicle and “Key Detected In Vehicle” may be shown
Cleaning and protecting
the vehicle exterior
Perform cleaning in a manner
appropriate to each compo-
nent and its material.
