Tires and loading on yourTo 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 283 and 355.
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 preten-
sioner removed and disposed of by the qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.
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.

NOTICE
Make sure the positive side and
negative side of the battery are
faced correctly.
 Do not replace the battery with wet
hands. Water may cause unexpected
rust.
 Do not touch or move any compo-
nents inside the transmitter, or it
may interfere with proper operation.
 Be careful not to bend the electrode
when inserting the transmitter bat-
tery and that dust or oils do not
adhere to the case.
 Close the transmitter case securely.
After replacing the battery, check that the
transmitter operates properly. If the trans-
mitter still does not operate properly, con-
tact your Toyota dealer. The smart key system consists mainly
of the following functions.
Engine immobilizer function (For de-
tails, see “Engine immobilizer system”
on page 16 in this Section.)
Wireless remote control function (For
details, see “Wireless remote control”
on page 18 in this Section.)
Push button start function (For details,
see “How to start the engine” on page
290 in Section 3.)
Entry function and start function (See
“ENTRY FUNCTION AND START
FUNCTION” described below.)
Steering lock function (See “STEERING
LOCK FUNCTION” described below.)
CAUTION
Weak radio waves emitted from the
smart key system may affect pace-
makers. If you or other passengers
use a pacemaker, use the vehicle only
after checking the pacemaker manual
to confirm that it is safe. If neces-
sary, the entry function can be dis-
abled. See “DISABLING THE SMART
KEY SYSTEM” on page 32 in this
Section.

Push the knob into the recessed position
when not in use.
NOTICE
Do not put unevenly weighted ob-
jects on the seat and do not stick
sharp objects (needles, nails, etc.)
into the seat.
 When cleaning the seats, do not
use organic substances (paint thin-
ner, benzine, alcohol, gasoline,
etc.). They may damage the seat
ventilation/heating system or seat
surface.
 Before cleaning the seats, fully
wring out the towel that will be
used. Water entering the seats may
cause the seat ventilation/heating
system to malfunction.
 To prevent the battery from being
discharged, turn the switches off
when the engine is not running.
Toyota strongly urges that the driver and
passengers in the vehicle be properly re-
strained at all times with the seat belts
provided. Failure to do so could increase
the chance of injury and/or the severity of
injury in accidents.
The seat belts provided for your vehicle
are designed for people of adult size,
large enough to properly wear them.
Child. Use a child restraint system ap-
propriate for the child until the child be-
comes large enough to properly wear the
vehicle’s seat belts. See “Child restraint”
on page 98 in this Section for details.
If a child is too large for a child restraint
system, the child s hould sit in the rear
seat and must be restrained using the
vehicle’s seat belt. According to accident
statistics, the child is safer when properly
restrained in the rear seat than in the
front seat.
If a child must sit in the front seat, the
seat belts should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may cause death or
serious injury to the child. Do not allow any children to stand up or
kneel on either rear or front seats. An
unrestrained child could suffer serious in-
jury or death during emergency braking or
a collision. Also, do not let the child sit
on your lap. Holding a child in your arms
does not provide sufficient restraint.
Pregnant woman.
Toyota recommends the
use of a seat belt. Ask your doctor for
specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips and not on the
waist.
Injured person. Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendations.
