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.
If the tread wear is uneven among the
installed tires,
If a compact spare tire, snow tires, or
tire chains are used,
If the tire pressure is excessively high-
er than specified, or if tire pressure is
suddenly reduced due to bursts or oth-
er causes,
If the vehicle is driven on a slippery
road surface such as rough road and
frozen road,
If the vehicle speed is less than 30
km/h (19 mph) or more than 100 km/h
(62 mph), and if the driving duration is
less than 5 minutes,

AFTER REPLACING OR ROTATING
TIRES OR WHEELS
Initial adjustment of the tire pressure
warning system is necessary after you
have replaced or rotated your tires or
wheels.
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 pres-
sures.
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.
Floor mat
Use a floor mat of the correct size.
If the floor carpet and floor mat have a
hole, then it is designed for use with a
locking clip. Fix the floor mat with locking
clip into the hole in the floor carpet.

IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see “Checking the engine oil level” in Sec-
tion 7−2.
Your engine is fitted with twin ground
electrode platinum−tipped spark plugs.
NOTICE
Use only twin ground electrode plati-
num−tipped spark plugs for your en-
gine performance.
Brake system
TANDEM MASTER CYLINDER BRAKE
SYSTEM
The tandem master cylinder brake system
is a hydraulic system with two separate
sub−systems. If either sub−system should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power−assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!

CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard—much harder than nor-
mal. And your braking distance will
be longer.
ANTI−LOCK BRAKE SYSTEM (with
“ABS” warning light)
The anti−lock brake system is designed to
automatically help prevent lock−up of the
wheels during sudden braking or braking
on slippery road surfaces. This assists in
providing directional stability and steering
performance of the vehicle under these
circumstances.
The anti−lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerate to a speed below
approximately 5 km/h (3 mph).You may hear a sound and feel a vibra-
tion in the engine compartment for a few
seconds when the engine is started or just
after the vehicle is started. This means
that the anti−lock brake system is in the
self check mode, and does not indicate a
malfunction.
Effective way to press the “ABS” brake
pedal: When the anti−lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti−lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. Pump-
ing the brake pedal makes the stopping
distance longer.
The brake pedal pulsation caused by the
anti−lock brake system may indicate haz-
ardous road surface conditions. Although
the anti−lock brake system assists in pro-
viding vehicle control, it is still important
to drive with all due care, because the
anti−lock brake system cannot overcome
the laws of physics that act on your ve-
hicle:
Braking capability is dependent on tire
friction with the road surface.
Even though the anti−lock brake sys-
tem is operating, a driver cannot main-
tain full control on certain slippery road
surfaces, when cornering at high
speeds, or in violent maneuvers.
Avoid high speeds on wet roads. The
anti−lock brake system cannot elimi-
nate the risk of hydroplaning and loss
of tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with
vehicles not fitted with an anti−lock brake
system, your vehicle may require a longer
stopping distance in the following cases:
Driving on rough, gravel or snow−cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differences
in surface height.

“ABS” warning light
The light comes on when the ignition key
is turned to the “ON” position. After a few
seconds, the light will go off.
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 as de-
scribed above, or remains on.
The light comes on while driving.
Even if the anti−lock brake system should
fail, the brake system will still operate
conventionally. However, when the “ABS”
warning light is on (and the brake system
warning light is off), the anti−lock brake
system is not assisting brake performance
so that the wheels can lock−up during
sudden braking or braking on slippery
road surfaces. Have your vehicle checked
by your Toyota dealer as soon as pos-
sible.
Brake pad wear limit indicators
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.

warning system is necessary after you
have replaced your tires. See ”Tire
pressure warning system” in Section
1−8.
Rotating tires
Steel wheels with a compact spare tire
and aluminum wheels
Steel wheels without a compact spare tire
To equalize the wear and help extend
tire life, Toyota recommends that you
rotate your tires approximately every
12000 km (7500 miles). However, the
most appropriate timing for tire rotation
may vary according to your driving hab-
its and road surface conditions.
See “If you have a flat tire” in Section 4
for tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, out−of−balance
wheels, or severe braking.
CAUTION
Do not include a compact spare tire
when rotating the tires. It is designed
for temporary use only.
Initial adjustment of the tire pressure
warning system is necessary after you
have rotated your tires. See ”Tire pres-
sure warning system” in Section 1−8.

Replacing wheels
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or they may
cause loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
This must be observed on compact spare
tires, too.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
Initial adjustment of the tire pressure
warning system is necessary after you
have replaced your wheels. See ”Tire
pressure warning system” in Section
1−8.
Aluminum wheel precautions
After driving your vehicle the first 1600
km (1000 miles), check that the wheel
nuts are tight.
If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).
When using tire chains, be careful not
to damage the aluminum wheels.
Use only the Toyota wheel nuts and
wrench designed for your aluminum
wheels.
When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.
As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.
