the following cond itions are met:
●The power switch is OFF.
●All doors are closed.
●The hood is closed.
■Remote Air Conditioning Sys-
tem automatic shut-off
The system will auto matically shut

battery is low
●When the EV system is cool (for
example, after being left for a long
time in low temperatures)
■Windshield defogger
When defogging the windshield
using the Remote Air Conditioning
System, defogging may be insuffi-
cient due to the power being
restricted more than during normal
air conditioning operation. Also, the
outside of the windshield may fog up
due to the outsi de temperature,
humidity or air conditioning set tem-
perature.

dition of the Remote Air Condition-
ing System, the e lectric fan may
spin and an operating noise may

However, this does not indicate a
malfunction.
●The Remote Air Conditioning Sys-
tem may stop operating temporar-
ily if other features that use

WARNING
■Precautions for the Remote
Air Conditioning System
●Do not use the system if people
are in the vehicle.
Even when the system is in use,
the internal temperature may
still reach a high or low level
due to features such as the
automatic shut-off. Children and
pets left inside the vehicle may
suffer heatstroke dehydration or
hypothermia, or could result in
death or serious injury.
●Depending on the surrounding
environment, signals from the
wireless switch may transmit
further than expected. Pay
appropriate attention to the
vehicle’s surroundings and use
the switch only when necessary.
●Do not operate “A/C” if the hood
is open. The air conditioning
may operate unintentionally and
objects may be drawn into the
electrical cooling fan.
NOTICE
■To prevent the traction bat-
tery from being discharged
through incorrect operation
Use “A/C” only when necessary.

Maintenance and care
 Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
 If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.
■Shampooing the carpets
There are several commercial foam-
ing-type cleaners available. Use a
sponge or brush to apply the foam.
Rub in overlapping circles. Do not
use water. Wipe dirty surfaces and
let them dry. Excellent results are
obtained by keeping the carpet as
dry as possible.
■Handling the seat belts
Clean with mild soap and lukewarm
water using a cloth or sponge. Also
check the belts periodically for
excessive wear, fraying or cuts.
■Front side window s with IR pro-
tective coating

the vehicle body. Otherwise
resin section, such as moldings
and bumpers, may be deformed
and damaged. Also, do not con-
tinuously hold the nozzle in the
same place.
●Do not spray the lower part of
the windshield continuously. If
water enters the air conditioning
system intake located near the
lower part of the windshield, the
air conditioning system may not
operate correctly.
●Do not wash the underside of
the vehicle usin g a high pres-
sure car washer. If water enters
the traction battery, the EV sys-
tem may malfunction.
●Do not use the washer on the
area around the charging port
lid. Water could get into the
charging inlet and could dam-
age the vehicle.
■Cleaning aluminum parts
When cleaning the hood, do not
push hard or put weight on it.
The aluminum part may be
dented.
