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

Important health and safety
information about your Toyota
CAUTION

WARNING: Engine exhaust, some of its constitu-
ents, and a wide variety of automobile compo-
nents contain or emit chemicals known to the

fects and other reproductive harm. In addition,
oils, fuels and fluids contained in vehicles as
well as waste produced by component wear con-
tain or emit chemicals known to the State of
California to cause cancer and birth defects or
other reproductive harm.

Battery posts, terminals and related accessories
contain lead and lead compounds. Wash your

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.

Your vehicle is supplied with the two
kinds of keys.
1. Master keys (black)ÐThese keys work
in every lock. Your Toyota dealer will
need one of them to make a new key
with a built±in transponder chip.
2. Sub key (gray)ÐThis key will not work
in the glove box.
A transponder chip for engine immobilizer
system has been placed in the head of
the master and sub keys. These chips are
needed to enable the system to function
correctly, so be careful not to lose these
keys. If you make your own duplicate key,
you will not be able to cancel the system
or start the engine.To protect items locked in the glove box
when using valet parking, leave the sub
key with the attendant.
Since the side doors can be locked with-
out a key, you should always carry a
spare key in case you accidentally lock
your keys inside the vehicle.NOTICE
When using a key containing a trans-
ponder chip, observe the following
precautions:

When starting the engine, do not
use the key with a key ring resting
on the key grip and do not press
the key ring against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts.

When starting the engine, do not
use the key with other transponder
keys around (including keys of oth-
er vehicles) and do not press other
key plates against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts. If
this happens, remove the key once
and then insert it again after remov-
ing other transporter keys (includ-
ing keys of other vehicles) from the
ring or while gripping or covering
them with your hand to start the
engine.
Do not bend the key grip.

Do not cover the key grip with any
material that cuts off electromagnet-
ic waves.

Do not knock the key hard against
other objects.

Do not leave the key exposed to
high temperatures for a long period,
such as on the dashboard and hood
under direct sunlight.

Do not put the key in water or
wash it in an ultrasonic washer.

Do not use the key with electromag-
netic materials.
