Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, it may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner 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 ve-
hicles have a significantly higher rollover rate than other
types of vehicles. This vehicle will handle and maneuver
differently from an ordinary passenger car because 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 fea-
ture causes this type of vehicle to be more likely to rol-
lover. 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 “Off–road vehicle precau-
tions” on page 234 in Section 2 and “Off–road driving pre-
cautions” on page 253 in Section 3.
