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 446 and 523.
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 the
floor around the driver ’s seat for several minutes. It does
not indicate a malfunction.
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.
Perchlorate Material
Special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate.
These components may include airbag, seat belt preten-
sioners, and wireless remote control batteries.

(k) “VSC” Warning Light
This light warns that there is a problem
somewhere in the vehicle stability control
system or traction control system.
The light will come on when the engine
switch is turned to “ON” and will go off
after a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the engine switch is turned to
“ON”.
The warning light remains on after the
engine switch is turned to “ON”.
The warning light comes on while driv-
ing.
Tw o −wheel drive models only—The “TRAC
OFF” indicator light will come on when the
“VSC” warning light comes on even if the
“TRAC OFF” switch is not pushed. (l) Low Tire Pressure Warning Light
This light warns that the tire pressure of
one or more of your tires (without the
spare tire) is low. The light comes on
when the engine switch is turned to the
“ON” position. It goes off after a few sec-
onds. This indicates that the tire pressure
warning system is functioning properly.
If the warning light comes on, stop your
vehicle in a safe place as soon as pos-
sible and check that the inflation pressure
of all four tires is as specified on the tire
and loading information label. (See
“Checking tire inflation pressure” on page
523 in Section 7
−2.) The light should go
off several minutes after the tire pressure
is adjusted.
If the warning light comes on after blink-
ing for 1 minute, the tire pressure warning
system may be malfunctioning. Contact
your Toyota dealer.
For details, see “Tire pressure warning
system” on page 214 in Section 1 −7. (m) Low Windshield Washer Fluid Level
Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see “Adding washer fluid” on page 539 in
Section 7 −3.)
(n) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the engine
switch is turned to “ON” and will go off
after about a few seconds.
When you drive for about 7200 km (4500
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the engine switch turned to the “ON”
position. If you continue driving without
replacing the engine oil, and if the dis-
tance driven exceeds 8000 km (5000
miles), the light will come on after the
engine switch is turned to “ON” position.
The light will remain on thereafter.
