681-3. 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.

■Tire pressure
• It may take a few minutes to dis- play the tire inflation pressure
after the power switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after inflation pressure
has been adjusted.
• “---” may be disp layed 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
pressure gauge.

NOTICE
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■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 vehi cle may acceler-
ate suddenly if the accelerator
pedal is accidentally depressed.
■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.
●When driving over bumps on
the road, drive as slowly as pos-
sible to avoid damaging the
wheels, underside of the vehi-
cle, etc.
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause
the following situations. Hold the
steering wheel firmly and gradu-
ally depress the brake pedal to
slow down the vehicle.
●It may be difficult to control your
vehicle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnor-
mally.
Information on what to do in case
of a flat tire (
P.461)
■When encountering flooded
roads
Do not drive on a road that has
flooded after h eavy 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 Toy-
ota dealer check the following:
●Brake function
●Changes in quantity and quality
of oil and fluid used for the
engine, hybrid transaxle (front
and rear [AWD models]), etc.
●Lubricant condition for bearings
and suspension joints (where
possible), and the function of all

■Matching trailer ball height to
trailer coupler height
No matter wh ich class of tow hitch
applies, for a m ore safe trailer
hookup, the trailer ball setup must
be the proper height for the coupler
on the trailer.

■Before towing
Check that the fo llowing conditions
are met:
●Ensure that your vehicle’s tires
are properly inflated. ( P.495)
●Trailer tires are inflated according
to the trailer manufacturer’s rec-
ommendation.
Trailer towing
Your vehicle is designed pri-
marily as a passen-
ger-and-load-carrying
vehicle. Towing a trailer can
have an adverse impact on
handling, performance,
braking, durability, and fuel
consumption. For your
safety and the safety of oth-
ers, you must not overload
your vehicle or trailer. You
must also ensure that you
are using appropriate tow-
ing equipment, that the tow-
ing equipment has been
installed correctly and used
properly, and that you
employ the requisite driv-
ing 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 additional require-
ments such as a towing kit,
etc.

Driving
cut-off function stops the power
flowing to the trailer lights to prevent
damage to the vehicle’s electrical
system.
This function is activated when the
rated current of any of the following
trailer light circuit components is
exceeded:
●Tail lights: maximum 4.5 A
●Stop/turn signal light (right): maxi-
mum 7.8 A
●Stop/turn signal light (left): maxi-
mum 4.5 A
■When the auto current cut func-
tion is activated
If a trailer light d oes not come on
due to the activation of the auto cur-
rent cut function , the light system
will need to be reset.
Follow the reset procedure shown
below.
●If a tail light doe s not come on,
turn off the headlight switch.
●If the right-side stop/turn signal
light does not com e on, put the
turn signal in the off position or
remove foot from t he brake pedal.
●If the left-side stop/turn signal light
does not come on, put the turn
signal in the off position or remove
foot from the brake pedal.
If the emergency flashers do not
operate, press the emergency
flasher switch to turn them off.
After the light syst em is reset, oper-
ate the light switches again to see if
the lights operate normally.
If the lights do not operate normally,
have the vehicle inspected by your
Toyota dealer.
Your vehicle will handle differ-
ently when towing a trailer. Help
to avoid an accident, death or
serious injury, keep the following
in mind when towing:
 Speed limits for towing a
trailer vary by state or prov-
ince. Do not exceed the
posted towing speed limit.
 Toyota recommends that the
vehicle-trailer speed limit is 65
mph (104 km/h) on a flat,
straight, dry road. Do not
exceed this limit, the posted
towing speed limit or the
speed limit for your trailer as
set forth in your trailer owner’s
manual, whichever is lowest.
Instability of the towing vehi-
cle-trailer combination (trailer
sway) increases as speed
increases. Exceeding speed
limits may cause loss of con-
trol.
 Before starting out, check the
trailer lights, tires and the
vehicle-trailer connections.
Recheck after driving a short
distance.
NOTICE
■Do not directly splice trailer
lights
Do not directly splice trailer lights.
Directly splicing trailer lights may
damage your vehicle’s electrical
system and cause a malfunction.
