heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping drugs, cold remedies, etc.)
● Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
● Do not use the seat heater more than necessary. Doing so may cause
minor burns or overheating.
NOTICE

Safety Connect LE
D light Indicators
When the engine switch is turned to the “ON” position (vehicles with-
out a smart key system) or the “ENGINE START STOP” switch is
turned to IGNITION ON mode (vehicl es with a smart key system), the
red indicator light comes on for 2 seconds then turns off. Afterward,
the green indicator light comes on, indicating that the service is
active.
The following indicator light patter ns indicate specific system usage
conditions:
● Green indicator light on = Active service
● Green indicator light flashing = Safety Connect call in process
● Red indicator light (except at v ehicle start-up) = System malfunc-
tion (contact your Toyota dealer)
● No indicator light (off) = Safety Connect service not active
Safety Connect services
■ Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision,
the system is design ed to automatically call the response center.
The responding agent receives th e vehicle’s location and attempts
to speak with the vehicle occupant s to assess the level of emer-
gency. If the occupants are unable to communicate, the agent
automatically treats the call as an emergency, contacts the nearest
emergency services provider to describe the situation, and
requests that assistance be sent to the location.

Safety information for Safety Connect
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 fo llowing U.S. and international
standards bodies.
● ANSI (American National Stand ards Institute) C95.1 [1992]
● NCRP (National Council on Radiation Protection and Measure-
ment) Report 86 [1986]
● ICNIRP (International Commiss ion on Non-Ionizing Radiation
Protection) [1996]
Those standards were based on comprehensive and periodic eval-
uations of the relevant scientific literature. Over 120 scientists,
engineers, 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.

CAUTION
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
■ When cleaning the windshield (vehicles with rain-sensing windshield
wiper)
● When the upper part of the windshield where the raindrop sensor is
located is touched by hand
● When a wet rag or similar is held close to the raindrop sensor
● If something bumps against the windshield
● If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
■ Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in hands
being caught or other serious injuries and
cause damage to the wiper blades.
