781-3. Emergency assistance
■Enhanced Roadside Assis-
tance
Enhanced Roadside Assistance
adds GPS data to the already
included warranty-based Toyota
roadside service.
Subscribers can press the
“SOS” button to reach a Safety
Connect response-center agent,
who can help with a wide range
of needs, such as: towing, flat
tire, fuel delivery, etc. For a
description of the Enhanced
Roadside Assistance services
and their limitations, please see
the Safety Connect Terms and
Conditions, which are available
at Toyota.com in the United
States, Toyotapr.com in Puerto
Rico and Toyota.ca in Canada.
Important! Read this informa-
tion before using Safety Con-
nect.
■Exposure to radio fre-
quency 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 wireless phones. Those
guidelines are consistent with
the safety standards 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
Measurement) Report 86
[1986]
 ICNIRP (International Com-
mission on Non-Ionizing Radi-
ation Protection) [1996]
Those standards were based on
comprehensive and periodic
evaluations of the relevant sci-
entific literature. Over 120 scien-
tists, engineers, and physicians
from universities, and govern-
ment health agencies and
industries reviewed the avail-
able body of research to
develop the ANSI Standard
(C95.1).
The design of Safety Connect
complies with the FCC guide-
lines in addition to those stan-
dards.

2164-1. Before driving
NOTICE
■Avoiding damage to vehicle
parts
●Do not turn the steering wheel
fully in either direction and hold
it there for an extended period
of time.
Doing so may damage the
power steering motor.
●When driving over bumps in the
road, drive as slowly as possible
to avoid damaging the wheels,
underside of the vehicle, etc.
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause
the following situations.
●It may be difficult to control your
vehicle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnor-
mally.
Hold the steering wheel firmly and
gradually depress the brake pedal
to slow down the vehicle.
Information on what to do in case
of a flat tire ( P.480, 490)
■When encountering flooded
roads
Do not drive on a road that has
flooded after heavy rain, etc.
Doing so may cause the following
serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by
water immersion
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your
Toyota dealer c heck the following:
●Brake function
●Changes in quantity and quality
of oil and fluid used for the
engine, hybrid transmission
(front and rear), etc.
●Lubricant condition for the bear-
ings and suspension joints
(where possible), and the func-
tion of all joints, bearings, etc.
■When parking the vehicle
Always set the parking brake, and
shift the shift lever to P. Failure to
do so may cause the vehicle to
move or the vehicle may acceler-
ate suddenly if t he accelerator
pedal is accidentally depressed.

2224-1. Before driving
■Before towing
Check that the fo llowing conditions
are met:
●Ensure that your vehicle’s tires
are properly inflated. ( P.523)
●Trailer tires are inflated according
to the trailer manufacturer’s rec-
ommendation.
●All trailer lights work as required
by law.
●All lights work each time you con-
nect them.
●The trailer ball is set at the proper
height for the coupler on the
trailer.
●The trailer is level when it is
hitched.
Do not drive if th e trailer is not
level, and check for improper
tongue weight, overloading, worn
suspension, or other possible
causes.
●The trailer cargo is securely
loaded.
●The rear view mirr ors conform to
all applicable fede ral, state/provin-
cial or local regulations. If they do
not, install rear view mirrors
appropriate for towing purposes.
■When towing a trailer
Disable the following systems, as
the systems may no t operate prop-
erly.
●LTA (Lane Tracing Assist)
(  P.278)
Trailer towing (with
towing package)
Your vehicle is designed
primarily as a passenger-
and-load-carrying vehicle.
Towing a trailer can have an
adverse impact on handling,
performance, braking, dura-
bility, and fuel consump-
tion. For your safety and the
safety of others, you must
not overload your vehicle or
trailer. You must also
ensure that you are using
appropriate towing equip-
ment, that the towing equip-
ment has been installed
correctly and used properly,
and that you employ the
requisite driving habits.
Vehicle-trailer stability and
braking performance are
affected by trailer stability,
brake performance and set-
ting, trailer brakes, the hitch
and hitch systems (if
equipped).
To tow a trailer safely, use
extreme care and drive the
vehicle in accordance with
your trailer’s characteris-
tics and operating condi-
tions.
Toyota warranties do not
apply to damage or mal-
function caused by towing a
trailer for commercial pur-
poses.
Contact your Toyota dealer for
further information about addi-
tional requirements such as a
towing kit, etc.
