■Charging the traction battery
Be sure to maintain the traction bat-
tery charge level suitable for your
driving needs.
If the traction battery fully dis-
charges, 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 message will be displayed
on the multi-information display.
(  P.515)
●If the traction batte ry is completely
discharged, the EV system cannot
be started and dri ving will not be
possible. When the traction bat-
tery 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
battery electric vehi cle for being off
when it is actually still running, as
indicated by the “READY” indicator
being illuminated. F or 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
vibrations may occur. However,
these sounds and/o r vibrations are
not signs of malfunctions:
●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 lug-
gage compartment.
●Electrical relay sounds may be
heard from the motor compart-
ment when the EV system starts or stops.
●Relay operating sounds such as a
snap or soft clank will be emitted
from the traction b
attery in the fol-
lowing situations:
• When the EV system is started or stopped
• When charging starts or com-
pletes
• When the vehicle is driven the first time after the traction battery has
been charged using DC charging
●Sounds may be heard due to
regenerative 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
conditioning system (air condition-
ing compressor, blower motor).
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do n ot dispose of the
vehicle yourself.
A sound which changes in
accordance with the driving
speed, will be played in order to
warn people nearby of the vehi-
cle’s approach. This sound may
be heard inside the vehicle. The
sound will stop when the vehicle
speed exceeds approximately
23 mph (37 km/h).
■Acoustic Vehicle Alerting Sys-
tem
In the following cases, the Acoustic
Vehicle Alerting System may be dif-
ficult for surrounding people to hear.

key of the vehicle if traveling
to a location with unreliable
communications.
 If the smartphone battery is
depleted, the smartphone
cannot be used as Digital Key.
If the battery level is low, be
sure to charge the smart-
phone prior to going out.
 The Digital Key system is
related to the Smart key sys-
tem. If the Smart key system
has been deactivated in the
vehicle customization setting,
the Digital Key will also be
disabled.
 Depending on the radio wave
environment, the Digital Key
may not be able to be used.
P. 1 8 8
 When transferring vehicle
ownership, make sure to
delete the Digital Keys.
 If the vehicle is not operated
for 14 days or more, the Digi-
tal Key will not connect auto-
matically. Therefore, it may
take some time before the
system operates after a door
handle is touched.
 A part of the services may be
stopped for a certain period of
time due to server mainte-
nance. However, registered
Digital Keys can be used
during the maintenance.
 A smartphone with the Digital
Key App enabled will be able to lock and unlock the doors,
start the EV system and per-
form any other operations as
same as the electronic key of
the vehicle. Be especially
careful not to lose the smart-
phone or allow it to be stolen.

Toyota dealer for an inspec-
tion or repairs, make sure to

3985-5. Driving tips
Owners Manual_USA_M42C01_en
WARNING
●When driving off-road or in rug-
ged terrain, do not drive at
excessive speeds, jump, make
sharp turns, strike objects, etc.
This may cause loss of control
or vehicle rollover causing
death or serious injury. You are
also risking expensive damage
to your vehicle’s suspension
and chassis.
NOTICE
■To prevent the water damage
Take all necessary safety mea-
sures to ensure that water dam-
age to the traction battery, EV
system or other components does
not occur.
●Water entering the motor com-
partment may cause severe
damage to the EV system.
●Water entering the transmis-
sion will cause deterioration in
transmission quality. The mal-
function indicator may come on,
and the vehicle may not be driv-
able.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the tran-
saxle case, reducing the gear
oil’s lubricating qualities.
■When you drive through
water
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the riverbed for
firmness. Drive slowly and avoid
deep water.
■Inspection after off-road driv-
ing
●Sand and mud that has accu-
mulated 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. For scheduled
maintenance information, refer
to the “Scheduled Maintenance
Guide” or “Owner’s Manual
Supplement”.

4487-1. Maintenance and care
Owners Manual_USA_M42C01_en
7-1.Maintenance and care
Working from top to bottom,
liberally 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
thoroughly with water.
 Wipe away any water.
 Wax the vehicle when the
waterproof coating deterio-
rates.
If water does not bead on a clean
surface, apply wax when the vehi-
cle body is cool.
■Self-restoring coat
The vehicle body has a self-restor-
ing 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 t he depth of the scratch and outside 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
vehicle. Make sure to extend the
mirrors before driving.
●Brushes used in automatic car
washes may scratch the vehicle
surface, parts (wheel, etc.) and
harm your vehicle’s paint.
●Rear spoiler 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.239.
■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 continuously.
■Note for a smart key system
●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, follow the following correc-
tion procedures to wash the vehi-
cle:
• Place the key in a position 6 ft. (2 m) 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-
saving mode to disable the smart
key system. ( P.188)
