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 contains
abrasives.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors
Start washing from the front of the
vehicle. 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.
●When it is necessary to set the
power switch to ACC with the shift
position held in N , refer to P.181.
■High pressure car washes
●As water may enter the cabin, do
not bring the nozzle tip near the
gaps around the doors or perime-
ter of the windows, or spray these
areas continuously.

■Before recharging
When recharging, the 12-volt bat-
tery produces hydrogen gas which
is flammable and explosive. There-
fore, observe the following precau-
tions before recharging:
●If recharging with the 12-volt bat-
tery installed on the vehicle, be
sure to disconnect the ground
cable.
●Make sure the charger is off when
connecting and disconnecting the
charger cables to the 12-volt bat-
tery.
■After recharging/reconnecting
the 12-volt battery
●Unlocking the doors using the
smart key system may not be pos-
sible immediately after reconnect-
ing the 12-volt battery. If this
happens, use the wireless remote
control or the mechanical key to
lock/unlock the doors.

freeze instead of washer fluid.
Doing so may cause streaking on
the vehicle’s painted surfaces, as
well as damaging the pump lead-
ing to problems of the washer
fluid not spraying.

When trouble arises
8-2.Steps to take in an emergency
If your vehicle needs
to be towed
If towing is necessary, we
recommend having your
vehicle towed by your Toy-
ota dealer or commercial
towing service, using a
wheel-lift type truck or flat-
bed truck.
Use a safety chain system
for all towing, and abide by
all state/provincial and local
laws.
WARNING
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
■When towing the vehicle
Be sure to transp ort the vehicle
with all four wheels raised off the
ground. If the vehicle is towed
with the tires co ntacting the
ground, the drivetrain and related
parts may be damaged, an acci-
dent may occur due to a change
in direction of the vehicle or elec-
tricity generated by the operation
of the motor may cause a fire to
occur depending o n the nature of
the damage or malfunction.
■While towing
●When towing using cables or
chains, avoid sudden starts, etc.
which place excessive stress on
the towing eyelets, cables or
chains. The towing eyelets,
cables or chains may become
damaged, broken debris may hit
people, and cause serious dam-
age.
●Do not perform any of the fol-
lowing as doing so may cause
the parking lock mechanism to
engage, locking the rear wheels
and possibly leading to an acci-
dent resulting in death or seri-
ous injury:
• Unfasten the driv er’s seat belt
and open the driver’s door.
