Tires and loading on your Toyota
Underinflated or overinflated tire inflation pres-
sure and the excess load may result in the
deterioration of steering ability and braking abil-
ity, leading to an accident. Check the tire infla-
tion pressure periodically 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 211 and 149.
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, 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 dis-
pose of your vehicle.
Sequential manual
transmission driving tips
(Models equipped with Sequential Manual
Transmission only)
The sequential manual transmission is a 6speed forward/
reverse transmission. With the basics of the traditional
manual transmission, the clutch operation and transmission
shifting is controlled electronically. Unlike automatic trans-
missions, this system does not upshift automatically at the
time of acceleration.
To understand the unique system and operation method of
the sequential manual transmission, read Section 16 on
page 85 thoroughly before driving. For starting procedures,
see “How to start the engine— ” on page 154 in Section 3.
Please refer to the “Important Information For Your
Sequential Manual Transmission” equipped in your vehicle
as well.

When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of nontoxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.
CAUTION
Do not modify, remove, strike or open
the seat belt pretensioner assemblies,
airbag sensor or surrounding area or
wiring. Failure to follow these instruc-
tions may prevent the seat belt pre-
tensioners from activating correctly,
cause sudden operation of the system
or disable the system, which could
result in death or serious injury. Con-
sult your Toyota dealer about any re-
pair and modification.
NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
seat belt pretensioners in some
cases.
Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Repairs on or near the seat belt
retractor assemblies
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repair made on or near the front
fenders, front end structure or con-
sole
