The “VSC” warning light and “TRAC
OFF” indicator/warning light come on
while driving, without pushing the
“TRAC OFF” switch.
Tire pressure warning system
The tire pressure warning system is de-
signed to provide warning when tire
pressure of any one of the tires is criti-
cally reduced while the vehicle is mov-
ing. The low tire pressure warning light
comes on to inform you that such low
tire pressure may hamper driving.
This system is not designed to operate
when the vehicle is stopped. Therefore,
check the tire pressures regularly. The
recommended cold tire pressures, tire size
and the vehicle capacity weight are on the
tire pressure label. (For instruction, see
“Checking tire pressure” in Section 7−2.)
Installed tires should be of the specified
size. They should be of the same size
and construction. If tires other than of the
specified size are used, or if tires of dif-
ferent sizes or constructions are mixed,
the tire pressure warning system will not
function properly.
LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the “ON” position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.
If the low tire pressure warning light
comes on while driving, adjust tire
pressure to the specified level. (See
“Tires” in Section 8.)
After the tire pressure is adjusted, the
light should go off after driving at about
more than 30 km/h (19 mph) for some
time. If the light still remains, have the
tire pressure warning system checked at
your Toyota dealer.

The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire pressure is
low, or it may come on when the tire
pressure is actually normal.
The tread wear is uneven among the
installed tires.
A compact spare tire, snow tires, or
tire chains are used.
The tire pressure is excessively higher
than specified, or tire pressure is sud-
denly reduced due to bursts or other
causes.
The vehicle is driven on a slippery
road surface such as rough road and
frozen road.
The vehicle speed is less than 30 km/h
(19 mph) or more than 100 km/h (62
mph), and the driving duration is less
than 5 minutes.
TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
Pushing this reset button after replac-
ing or rotating tires or wheels memo-
ries the present tire condition as a
standard.
After replacing or rotating the tires or
wheels, perform the initial adjustment as
follows.
1. Park the vehicle at a safe place and
apply the parking brake. Stop the en-
gine.
2. Adjust pressures of all the installed
tires to the specified level. (See “Tires”
in Section 8.)
3. Turn the ignition key to “ON”.4. With the vehicle stopped, push the re-
set switch on the left lower instrument
panel and hold it until the low tire
pressure warning light blinks for three
times.
5. The initial adjustment is completed af-
ter driving at the speeds of 30 km/h
(19 mph) or over for about total 8
hours, when the tire pressure warning
system detects the normal tire pressur-
es.
Do not push the reset switch without ad-
justing the tire pressure to the specified
level. Otherwise, the low tire pressure
warning light may not come on even if the
tire pressure is low, or it may come on
when the tire pressure is actually normal.
If you push the reset switch while the
vehicle is moving, the initial adjustment is
not performed.
If the low tire pressure warning light does
not blink when you push and hold the
reset switch, have the low pressure warn-
ing system checked at your Toyota dealer.

GASOLINE QUALITY
In a very few cases, you may experience
driveability problems caused by the partic-
ular gasoline that you are using. If you
continue to have unacceptable driveability,
try changing gasoline brands. If this does
not rectify your problem, then consult your
Toyota dealer.
NOTICE
Do not use gasohol other than
stated above. It will cause fuel sys-
tem damage or vehicle performance
problems.
If driveability problems occur (poor
hot starting, vaporizing, engine
knock, etc.), discontinue the use.
Take care not to spill gasohol dur-
ing refueling. Gasohol may cause
paint damage.
FUEL TANK CAPACITY

Fuel pump shut off system
The fuel pump shut off system stops sup-
plying fuel to the engine to minimize the
risk of fuel leakage when the engine stalls
or an airbag inflates upon collision. To
restart the engine after the fuel pump shut
off system activates, turn the ignition
switch to “ACC” or “LOCK” once and start
it.
CAUTION
Inspect the ground under the vehicle
before restarting the engine. If you
find that liquid has leaked onto the
ground, it is the fuel system has
been damaged and it is in need of
repair. In this case, do not restart the
engine.
Operation in foreign countries
If you plan to drive your Toyota in
another country...
First, comply with the vehicle registration
laws.
Second, confirm the availability of the cor-
rect fuel (unleaded and minimum octane
number).

Three−way catalytic converter
The three−way catalytic converter is an
emission control device installed in the
exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION
Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.
NOTICE
A large amount of unburned gases
flowing into the three−way catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
Use only unleaded gasoline.
Do not drive with an extremely low
fuel level; running out of fuel could
cause the engine to misfire, creat-
ing an excessive load on the three−
way catalytic converter.
Do not allow the engine to run at
idle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not push−start or pull−start your
vehicle.
Do not turn off the ignition while
the vehicle is moving.
Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic ignition
system/distributor ignition system
or fuel system could cause an ex-
tremely high three−way catalytic
converter temperature.
If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check−up as soon
as possible. Remember, your Toyota
dealer knows your vehicle and its
three−way catalytic converter sys-
tem best.
To ensure that the three−way cata-
lytic converter and the entire emis-
sion control system operate proper-
ly, your vehicle must receive the
periodic inspections required by the
Toyota Maintenance Schedule. For
scheduled maintenance information,
refer to the “Scheduled Maintenance
Guide” or “Owner ’s Manual Supple-
ment”.

“ABS” warning light
The light comes on when the ignition key
is turned to the “ON” position. If the anti−
lock brake system and the brake assist
system work properly, the light turns off
after a few seconds. Thereafter, if either
of the systems malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake system, the brake assist
system, the traction control system and
the vehicle skid control system do not
operate, but the brake system still oper-
ates conventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.If either of the following conditions
occurs, this indicates a malfunction
somewhere in the parts monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the anti−lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
