The power outlet can be used when
The engine is running.
■ The indicator light changes according to the maximum available
capacity as follows:
■ When the power outlet is in operation
The sound of the cooling fan may be heard from the right side of the luggage
compartment. This is normal and does not indicate a malfunction.
■ If the engine is started with the power outlet main switch on
The maximum capacity of the power supply may decrease to below the stan-
dard, or may be cut off completely, even when the vehicle is stationary.
■ The protection circuit may be activated to cut the power supply if any
of the following conditions apply:
● The engine is started with the power outlet main switch on.
● Use of electrical appliances exceeding the maximum capacity is
attempted.
A sound may be heard when the protection circuit is activated. This is nor-
mal and does not indicate a malfunction.
● Electrical appliances, which consume power exceeding 100 W, have
been used continuously for a long time period.
● The total power usage by all electrical features (headlights, air condition-
ing, etc.) has exceeded the total vehicle maximum for an extended
period of time.

CAUTION
■
Burns
● Use caution when seating the following persons in a seat with the seat
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
■To prevent seat heater damage
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.

Floor mat
CAUTION
Observe the following precautions.
Failure to do so may cause the driver's floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle, leading to a serious accident.
■When installing the driver's floor mat
● Do not use floor mats designed for other models or different model year
vehicles, even if they are Toyota Genuine floor mats.
● Only use floor mats designed for the driver's seat.
● Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
■ Before driving
Use only floor mats designed specifically for vehicles of the same
model and model year as your vehic le. Fix them securely in place
onto the carpet.
Fix the floor mat in place using
the retaining hooks (clips) pro-
vided.
The shape of the retaining
hooks (clips) and the fixing
procedure of the floor mat for
your vehicle may differ from
those shown in the illustration.
For details, refer to the floor
mat retention clip installation
instructions supplied with the
clips.
● Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
● With the engine stopped and the shift
lever in P, fully depress each pedal to
the floor to make sure it does not inter-
fere with the floor mat.

Safety Connect LED light IndicatorsWhen the “ENGINE START STOP” switch is turned to IGNITION ON
mode (vehicles with a smart key system) or the engine switch is
turned to the “ON” position (vehicle s without 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) = Safe ty 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 occup ants 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 ConnectImportant! 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 Stand ards Institute) C95.1 [1992]
● NCRP (National Council on Ra diation 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.

Aluminum wheels (if equipped)
● Remove any dirt immediately by using a neutral detergent. Do not use
hard brushes or abrasive cleaners. Do not use strong or harsh chemical
cleaners. Use the same mild detergent and wax as used on the paint.
● Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
● Wash detergent from the wheels immediately after use.
■ Bumpers and side moldings
Do not scrub with abrasive cleaners.
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.
■ Precautions regardin g 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.
