761-2. Emergency assistance
■Enhanced Roadside Assistance
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 Connec t
response-center agent, who can he lp with a wide range of needs,
such as: towing, flat tire, fuel delivery, etc. For a description of the
Enhanced Roadside Assistance se rvices and their limitations,
please see the Safety Connect Te rms 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 informatio n before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-po wer
radio transmitter and receiver. I t 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 wi re-
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 Radi ation 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 scienti fic literature. Over 120 scientists, engi-
neers, and physicians from unive rsities, 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 i n
addition to those standards.

●Setting items are not selectable during driving and cannot be o perated.
Also, the settings screen is temporarily canceled in the follow ing situations.
• A warning message is displayed.
• The vehicle starts off.
● Settings for functions not equipped to the vehicle are not displayed.
● When a function is turned off, the related settings for that fu nction are not
selectable.
■ Pop-up display
In some situations, such as when a switch operation is performe d, a pop-up
display will be temporarily displayed on the multi-information display.
■ When disconnecting and reco nnecting battery terminals
The drive information will be reset.
■ Ending display
When the engine switch is turned off, each of the following wil l be displayed
on the multi-information display, and will extinguish after app roximately
30 seconds.
● Distance traveled
● Average fuel economy
● Distance to empty
■ Tire inflation pressure (vehicles with tire pressure warning sy stem)
● It may take a few minutes to display the tire inflation pressur e after 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 may
also take a few minutes to display the tire inflation pressure after inflation
pressure has been adjusted.
● “---” may be displayed if the tire position information cannot be determined
due to unfavorable radio wave conditions.
● Tire inflation pressure changes with temperature. The displayed values may
also be different from the values measured using a tire pressur e gauge.

Driving
NOTICE
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 511)
■ When encountering flooded roads or waterlogged 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
● Rubber or mechanical part damage or poor lubrication due to grease
being washed away, or grease becoming contaminated with mud or dirt
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, transfer (4WD models) differentials, etc.
● Lubricant condition for the propeller shaft, clutch fork, beari ngs and sus-
pension joints (where possible), and the function of all joints, bearings, etc.

Your vehicle will handle differently when towing a trailer. To help avoid
an accident, death or serious injury, keep the following in min d when
towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted to wing speed limit.
● Toyota recommends that the vehicl e-trailer speed limit is 65 mph
(104 km/h) on a flat, straight, dry road. Do not exceed this li mit, the
posted towing speed limit or the speed limit for your trailer a s set
forth in your trailer owner’s manu al, whichever is lowest. Instability
of the towing vehicle-trailer combination (trailer sway) increa ses as
speed increases. Exceeding speed limits may cause loss of contr ol.
● Before starting out, check the trailer lights, tires and the vehicle-
trailer connections. Recheck af ter driving a short distance.
● Practice turning, stopping and reversing with the trailer attac hed in
an area away from traffic until you become accustomed to the fe el
of the vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires pra ctice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the rig ht to
move the trailer to the right. (This is generally opposite to r eversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
● As stopping distance is increased when towing a trailer, vehicl e-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least one v ehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in the trailer jack-
knifing and a loss of vehicle control. This is especially true on wet or
slippery surfaces.
● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before maki ng
a turn.
● Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by mak ing
a wider than normal turning radius.
Trailer towing tips

1964-1. Before driving
■Matching trailer ball height to trailer coupler height
■ Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 551)
● Trailer tires are inflated according to the trailer manufacture r’s recommen-
dation.
● All trailer lights work as required by law.
● All lights work each time you connect 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 the trailer is not level, and check for imprope r tongue weight,
overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors ap propriate for tow-
ing purposes.
● Depress power mode button (vehicles with an automatic transmiss ion).
( P. 212)
No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper
height for the coupler on the trailer.
