Important information about your Toyota
Occupant restraint systems
Toyota encourages you and your family to take the time to
read Section 1±3 of this Owner 's Manual carefully. In
terms of helping you understand how you can receive the
maximum benefit of the occupant restraint systems this
vehicle provides, Section 1±3 of this Owner 's Manual is
the most important Section for you and your family to
read.
Section 1±3 describes the function and operation concern-
ing seats, seat belts, SRS airbags and child restraint sys-
tems of this vehicle and some potential hazards you
should be aware of. These systems work together along
with the overall structure of this vehicle in order to provide
occupant restraint in the event of a crash. The effect of
each system is enhanced when it is used properly and
together with other systems. No single occupant restraint
system can, by itself, provide you or your family with the
equal level of restraint which these systems can provide
when used together. That is why it is important for you and
your family to understand the purpose and proper use of
each of these systems and how they relate to each other.
The purpose of all occupant restraint systems is to help
reduce the possibility of death or serious injury in the
event of a collision. None of these systems, either individ-
ually or together, can ensure that there is no injury in the
event of collision. However, the more you know about
these systems and how to use them properly, the greater
your chances become of surviving an accident without
death or serious injury.
Seat belts provide the primary restraint to all occupants of
the vehicle, and every occupant of the vehicle should wear
seat belts properly at all times. Children should always be
secured in child restraint systems that are appropriate for
their age and size. SRS (Supplemental Restraint System)
airbags are, as their names imply, designed to work with,
and be supplemental to, seat belts and are not substitutes
for them. SRS airbags can be very effective in reducing
the risk of head and chest injuries by preventing contact of
the head and chest with interior portions of the vehicle.

2005 SEQUOIA from Aug. '04 Prod. (OM34424U)
In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS air-
bags makes the SRS airbags themselves potential sources
of serious injury if an occupant is too close to an airbag,
or if an object or some part of his or her body has been
placed between the occupant and the airbag at the time of
deployment. This is just one example of how the instruc-
tions in Section 1±3 of this Owner 's Manual will help en-
sure proper use of the occupant restraint systems, and
increase the safety they can provide to you and your fami-
ly in the event of an accident.
Toyota recommends you to read the provisions in Section
1±3 carefully and refer to them as needed during your time
of ownership of this vehicle.Event data recorder
Your vehicle has computers that monitor and control cer-
tain aspects of your vehicle. These computers assist in
driving and maintaining optimal vehicle performance. Be-
sides storing data useful for troubleshooting, there is a
system to record data in a crash or a near car crash
event. This is called an Event Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car crash event, this device records some
or all of the following information:

Engine speed

Whether the brake pedal was applied or not

Vehicle speed

To what extent the accelerator pedal was depressed

Position of the transmission selector lever

Whether the driver and front passenger wore the seat
belts or not

Driver 's seat position

Front passenger 's occupant classification

SRS airbag deployment data

SRS airbag system diagnostic data
The information above is intended to be used for the
purpose of improving vehicle safety performance. Unlike
general data recorders, the EDR does not record sound
data such as conversation between passengers.
Toyota will not disclose the data recorded in an EDR to a
third party except when:

An agreement from the vehicle's owner (or the leas-
ing company for a leased vehicle) is obtained

Officially requested by the police or other authorities

Used as a defense for Toyota in a law suit

Ordered by the court
However, if necessary Toyota will:

Use the data for research on Toyota vehicle safety
performance

Disclose the data to a third party for research pur-
poses without disclosing details of the vehicle owner,
and only when it is deemed necessary

Disclose summarized data cleared of vehicle identifi-
cation information to a non±Toyota organization for
research purposesNew vehicle warranty
Your new vehicle is covered by the following Toyota
limited warranties:

New vehicle warranty

Emission control systems warranty

For further information, please refer to the ªOwner's
Warranty Information Bookletº or ªOwner 's Manual

maintenance
It is the owner 's responsibility to make sure that the
specified maintenance is performed. Section 6 gives de-
tails of these maintenance requirements. Also included

Tires and loading on your
To y o t a
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner 's Manual. For details about tire inflation
pressure and load limits, see pages 429 and 355.
Scrapping of your Toyota
The SRS airbag and front seat belt pretensioner devices
in your Toyota contain explosive chemicals. If the ve-
hicle is scrapped with the airbags and pretensioners left
as they are, this may cause an accident such as fire.
Be sure to have the systems of the SRS airbag and
seat belt pretensioner removed and disposed of by a
qualified service shop or by your Toyota dealer before
you dispose of your vehicle.

On±pavement and off±road
driving tips
This vehicle belongs to the utility vehicle class. Utility
vehicles have a significantly higher rollover rate than
other types of vehicles. This vehicle will handle and
maneuver differently from an ordinary passenger car be-
cause it is designed for off±road use also. In addition,
this vehicle has a higher ground clearance and center of
gravity than that of an ordinary passenger car. This
vehicle design feature causes this type of vehicle to be
more likely to rollover. Failure to operate this vehicle
correctly may result in loss of control, accidents or
vehicle rollover causing death or serious injury. Be sure
to read ªOff±road vehicle precautionsº on page 334 in
Section 2 and ªOff±road driving precautionsº on page
365 in Section 3.
Leak detection pump
This pump performs fuel evaporation leakage check. This
check is done approximately five hours after the engine is
turned off. So you may hear sound coming from under-
neath the luggage compartment for several minutes. It
does not indicate a malfunction.
