(a) Brake System Warning Light
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
When the parking brake is applied...
The light comes on for a few seconds
when the ignition key is turned to the
“ON” position even after the parking brake
is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Scion dealer in the following cases:
The light does not come on even if the
parking brake is applied when the igni-
tion key is in the “ON” position.
The light does not come on even if the
ignition key is turned to the “ON” posi-
tion with the parking brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Scion dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the anti–lock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer acts as a reminder
to have the driver buckle up the seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes and
the buzzer sounds if the driver’s seat belt
is not fastened. Unless the driver fastens
the belt, the light continues flashing and
the buzzer sounds for about 6 seconds.
(c) Front Passenger ’s Seat Belt Reminder Light
The light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt. Howev-
er, if a front passenger uses an additional
seat cushion, the light may not flash even
when the seat belt is not buckled up.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built–in sensors in the seat cushion may
detect the pressure, causing the reminder
light to flash.

The loading is over the limit or imbal-
anced.
Initialization was not performed correct-
ly after replacing or rotating tires or
wheels.
The outside temperature is below 0
C
(32 F) or above 40 C (104 F).
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Adjust the tire inflation pressure to
the specified level as soon as pos-
sible.
Avoid abrupt steering wheel maneu-
vering and braking. If the vehicle
tires deteriorate, you could lose
control of the steering wheel or the
brakes, causing death or serious in-
jury.
Note: The tire pressure monitoring
system on your vehicle will warn you
when one of your tires is significantly
under–inflated and when some com-
binations of your tires are significant-
ly under–inflated. However, there are
other combinations of significantly
under–inflated tires for which your
tire pressure monitoring system may
not warn you. These other combina-
tions are relatively common, account-
ing for approximately half the
instances in which vehicles have sig-
nificantly under–inflated tires. For ex-
ample, your system may not warn you
when both tires on the same side or
on the same axle of your vehicle are
significantly under–inflated. It is par-
ticularly important, therefore, for you
to check the tire pressure in all of
your tires regularly and maintain
proper pressure.

TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
The tire pressure warning system needs
to be initialized in the following condi-
tions:
When the low tire pressure warning
light blinks twice every second
After replacing or rotating tires or
wheels
When initializing the system, the pres-
ent tire condition is stored as a stan-
dard.

20T002
Your engine is fitted with iridium–tipped
spark plugs.
NOTICE
Use only iridium–tipped spark plugs
and do not adjust gaps for your en-
gine performance and smooth drivabil-
ity.
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 increase. 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
increase.
ANTI–LOCK BRAKE SYSTEM
The anti–lock brake system is designed
to automatically help prevent lock–up of
the wheels during a sudden braking or
braking on slippery road surfaces. This
assists in providing directional stab ility
and steering performance of the vehicle
under these circumstances.

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
Scion dealer.
In this case, not only the anti–lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
DRUM–IN–DISC TYPE PARKING BRAKE
SYSTEM
Your vehicle has a drum–in–disc type
parking brake system. This type of brake
system needs bedding–down of the brake
shoes periodically or whenever the parking
brake shoes and/or drums are replaced.
Have your Scion dealer perform the bed-
ding–down.
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 Scion deal-
er as soon as possible. Expensive rotor
damage can result if the pads are not
replaced when necessary.The vehicle identification number (VIN)
is the legal identifier for your vehicle.
This number is on the left top of the
instrument panel, and can be seen
through the windshield from outside.
This is the primary identification number
for your Scion. It is used in registering
the ownership of your vehicle.

NOTICE
Do not crank for more than 30 se-
conds at a time. This may overheat
the starter and wiring systems.
 Do not race a cold engine.
 If the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Always slow down in gusty crosswinds.
This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp–edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on a bumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in “P” (automatic) or in first or
reverse (manual). If necessary, block
the wheels.
Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Scion dealer for assistance.
CAUTION
Before driving off, make sure the
parking brake is fully released and
the parking brake reminder light is
off.
Do not leave your vehicle unat-
tended while the engine is running.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking could cause
the vehicle to skid or spin.
Tips for driving in various
conditions

162
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high–speed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are high–speed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.
Winter driving tips
Make sure you have a proper freeze
protection for engine coolant.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non–silicate, non–amine, non–nitrite,
and non–borate coolant with long–life
hybrid organic acid technology. (Coolant
with long–life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See “Checking the engine coolant level”
on page 212 for details of coolant type
selection.
“Toyota Super Long Life Coolant” is a
mixture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about –35C (–31 F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7–3 tells you how to visually
inspect the battery. Your Scion dealer and
most service stations will be pleased to
check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 211 for recommended viscosity.
Leaving a heavy summer oil in your ve-
hicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Scion deal-
er—they will be pleased to help.
Keep the door locks from freezing.
Squirt lock de–icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before
inserting it.
