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.

Keys
SB12039
Your vehicle is supplied with two kinds
of keys.1. Master keys (black)—These keys work in every lock. Your Toyota dealer will
need one of them to make a new key
with a builtin transponder chip.
2. Sub key (gray)—This key will not work in the glove box and luggage space. 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
or luggage space when using valet park-
ing, leave the sub key with the attendant.
Since the doors can be locked without a
key, you should always carry a spare
master key in case you accidentally lock
your keys inside the vehicle.
SY12001
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.
