5-1. Using the air conditioning system and defogger

SIENNA_OM_OM08035U_(U)

Using automatic mode

Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions. 
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after 

 is pressed.

When the outside temperature exceeds 75°F (24°C) and the air condition-
ing system is on

In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. 
This may also reduce fuel consumption.

Recirculated air mode is selected as a default mode when the engine switch
is  turned  to  the  “ON”  position  (vehicles  without  a  smart  key  system)  or
IGNITION ON mode (vehicles with a smart key system).

It is possible to switch to outside air mode at any time by pressing 

.

Fogging up of the windows

The  windows  will  easily  fog  up  when  the  humidity  in  the  vehicle  is  high.
Pressing 

  on  will  dehumidify  the  air  from  the  outlets  and  defog  the

windshield effectively.

If you turn “A/C” off, the windows may fog up more easily.

The windows may fog up if the recirculated air mode is used.

Outside/recirculated air mode

When driving on dusty roads such as tunnels or in heavy traffic, set 
to the recirculated air mode. This is effective in preventing outside air from
entering  the  vehicle  interior.  During  cooling  operation,  setting  the  recircu-
lated air mode will also cool the vehicle interior effectively.

Outside/recirculated  air  mode  may  automatically  switch  depending  on  the
temperature setting or the inside temperature.

(

P. 540)

When 

 

is selected for the air outlets used

For your driving comfort, air flowing to the feet may be warmer than air flow-
ing to the upper body depending on the temperature setting.

When the outside temperature is low

The dehumidification function may not operate even when 

 is pressed.

When “A/C ON” flashes in the display

Press 

 and turn off the air conditioning system before turning it on once

more. There may be a problem in the air conditioning system if “A/C ON” con-
tinues to flash. Turn the air conditioning system off and have it inspected by
your Toyota dealer.

Ventilation and air conditioning odors

To let fresh air in, set the air conditioning system to the outside air mode.

During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.

To reduce potential odors from occurring: 
• It is recommended that the air conditioning system be set to outside air

mode prior to turning the vehicle off.

• The start timing of the blower may be delayed for a short period of time

immediately  after  the  air  conditioning  system  is  started  in  automatic
mode.

WARNING

To prevent the windshield from fogging up

Do not use 

 during cool air operation in extremely humid weather.

The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.

To prevent burns

Do not touch the rear view mirror surfaces when the outside rear view mir-
ror defoggers (vehicles with outside rear view mirror defoggers) are on.

Do not touch the glass at lower part of the windshield or to the side of the
front pillars when the windshield wiper de-icer is on. (vehicles with wind-
shield wiper de-icer)

NOTICE

To prevent battery discharge

Do not leave the air conditioning system on longer than necessary when the
engine is stopped.

Do not place anything on the instrument
panel  which  may  cover  the  air  outlets.
Otherwise,  air  flow  may  be  obstructed,
preventing  the  windshield  defoggers
from defogging.

Safety Connect Services Information

Phone  calls  using  the  vehicles  Bluetooth

®

  technology  will  not  be  possible

during Safety Connect.

Safety Connect is available beginning Fall 2009 on select Toyota models (in
the  contiguous  United  States  only).  Contact  with  the  Safety  Connect
response center is dependent upon the telematics device being in operative
condition, cellular connection availability, and GPS satellite signal reception,
which  can  limit  the  ability  to  reach  the  response  center  or  receive  emer-
gency  service  support.  Enrollment  and  Telematics  Subscription  Service
Agreement  are  required.  A  variety  of  subscription  terms  is  available;
charges vary by subscription term selected and location.

Automatic Collision Notification, Emergency Assistance and Stolen Vehicle
Location  are  available  in  the  United  States,  including  Hawaii  and Alaska,
Puerto Rico and Canada, and Enhanced Roadside Assistance are available

Automatic Collision Notification

In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding  agent  receives  the  vehicle’s  location  and  attempts  to
speak with the vehicle occupants to assess the level of emergency.
If  the  occupants  are  unable  to  communicate,  the  agent  automati-
cally  treats the call  as  an  emergency,  contacts  the  nearest emer-
gency services provider to describe the situation, and requests that
assistance be sent to the location.

Stolen Vehicle Location

If your vehicle is stolen, Safety Connect can work with local author-
ities to assist them in locating and recovering the vehicle. After filing
a police report, call the Safety Connect response center at 1-855-
405-6500 in the United States, 1-877-855-8377 in Puerto Rico or 1-
888-869-6828 in  Canada,  and  follow  the prompts  for  Safety Con-
nect to initiate this service.
In  addition  to assisting law enforcement with  recovery of  a stolen
vehicle, Safety-Connect-equipped vehicle location data may, under
certain  circumstances,  be  shared  with  third  parties  to  locate  your
vehicle. Further information is available at Toyota.com in the United
States, Toyotapr.com in Puerto Rico and Toyota.ca in Canada.

Emergency Assistance Button (“SOS”)

In the event of an emergency on the road, push the “SOS” button to
reach  the  Safety  Connect  response  center.  The  answering  agent
will determine your vehicle’s location, assess the emergency, and
dispatch the necessary assistance required.

If  you  accidentally  press  the  “SOS”  button,  tell  the  response-center
agent that you are not experiencing an emergency.

Important! Read this information before using Safety Connect.

Exposure to radio frequency signals

The Safety Connect system installed in your vehicle is a low-power
radio transmitter and receiver. It receives and also sends out radio
frequency (RF) signals.
In August  1996,  the  Federal  Communications  Commission  (FCC)
adopted RF exposure guidelines with safety levels for mobile wire-
less phones. Those guidelines are consistent with the safety stan-
dards  previously  set  by  the  following  U.S.  and  international
standards bodies.

ANSI (American National Standards Institute) C95.1 [1992]

NCRP (National  Council  on  Radiation  Protection  and Measure-
ment) Report 86 [1986]

ICNIRP  (International  Commission  on  Non-Ionizing  Radiation
Protection) [1996]

Those standards were based on comprehensive and periodic eval-
uations of the relevant scientific literature. Over 120 scientists, engi-
neers,  and  physicians  from  universities,  and  government  health
agencies and industries reviewed the available body of research to
develop the ANSI Standard (C95.1).
The design of Safety Connect complies with the FCC guidelines in
addition to those standards.

Cleaning and protecting the vehicle exterior

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 deteriorates.

If  water  does  not  bead  on  a  clean  surface,  apply  wax  when  the  vehicle
body is cool.

Automatic car washes

Before washing the vehicle:
• Fold the mirrors.
• Turn off the power back door system. (if equipped)
• Turn off the power sliding door system. (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 and
harm your vehicle’s paint.

High pressure car washes

Do not allow the nozzles of the car wash to come within close proximity of
the windows.

Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.

When using a car wash (vehicles with a smart key system)

If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. Place the key in a posi-
tion 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.)

If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.

Perform  the  following  to  protect  the  vehicle  and  maintain  it  in
prime condition:
