Oil is also used to lubricate the stems
of the intake valves. Some of this oil
is sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven.
More oil is consumed by high −speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
Oil consumption: Max. 1.0 L per 1000
km (1.1 qt./600 miles, 0.9 lmp.qt./600
miles)
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately. As an example, if a vehicle is used for
repeated short trips, and consumes a nor-
mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This
is because the oil is gradually becoming
diluted with fuel or moisture, making it
appear that the oil level has not changed.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an express way, making it
appear that oil is excessively consumed
after driving at high speeds.
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. Scion 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” on
page 246.

Keep the front wheels in proper
alignment.
Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.
Keep your vehicle tunedup and in
top shape. A dirty air cleaner,
improper valve clearance, dirty plugs,
dirty oil and grease, brakes not
adjusted, etc. all lower engine
performance and contribute to poor fuel
economy. For longer life of all parts
and lower operating costs, keep all
maintenance work on schedule, and if
you often drive under severe
conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance
information, please refer to the
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.)
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is run-
ning.

205
If your vehicle overheats
If your high engine coolant temperature
warning light flashes to indicate over-
heating, if you experience a loss of
power, or if you hear a loud knocking
or pinging noise, the engine has prob-
ably overheated. You should follow this
procedure...1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in “P”
(automatic) or neutral (manual) and ap-
ply the parking brake. Turn off the air
conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running and make sure the electric
cooling fan is operating. If it is not,
turn the engine switch off.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Look for obvious coolant leaks from theradiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the coolant is leaking, stop the en-gine immediately. Call a Scion dealer
for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
6. After the engine coolant temperaturehas cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Scion dealer.

207
NOTICE
Do not continue driving with a
deflated tire. Driving even a short
distance can damage a tire and
wheel beyond repair.
SU41031
Compact spare tire
The compact spare tire is designed
for temporary emergency use only.
The compact spare tire is identified
by the distinctive wording “TEM-
PORARY USE ONLY” molded into the
side wall of the tire.
To keep the compact spare tire no-
ticeable, do not hide the wheel by a
wheel cover or such.
The compact spare tire saves space
in your luggage compartment, and its
lighter weight helps to improve fuel
economy and permits easier installa-
tion in case of a flat tire.
The compact spare tire can be used
many times, if necessary. It has tread
life of up to 4800 km (3000 miles) de-
pending on road conditions and your
driving habits. When treadwear indi-
cators appear on the tire, replace the
tire.
See also the tire information on page
252 for details on the treadwear indi-
cators and other service information.

Scion, through its diligent research, design
and use of the most advanced technology
available, helps prevent corrosion and pro-
vides you with the finest quality vehicle
construction. Now, it is up to you. Proper
care of your Scion can help ensure long−
term corrosion prevention.
The most common causes of corrosion
to your vehicle are:
The accumulation of road salt, dirt and
moisture in hard −to −reach areas under
the vehicle.
Chipping of paint, or undercoating
caused by minor accidents or by
stones and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmental condi-
tions:
Road salt or dust control chemicals will
accelerate corrosion, as will the pres-
ence of salt in the air near the sea −
coast or in areas of industrial pollution.
High humidity accelerates corrosion es-
pecially when temperatures range just
above the freezing point.
Wetness or dampness to certain parts
of your vehicle for an extended period
of time, may cause corrosion even
though other parts of the vehicle may
be dry.
High ambient temperatures can cause
corrosion to those components of the
vehicle which do not dry quickly due to
lack of proper ventilation.
The above signifies the necessity to keep
your vehicle, particularly the underside, as
clean as possible and to repair any dam-
age to paint or protective coatings as
soon as possible.
To help prevent corrosion on your
Scion, follow these guidelines:
Wash your vehicle frequently. It is, of
course, necessary to keep your vehicle
clean by regular washing, but to prevent
corrosion, the following points should be
observed:
If you drive on salted roads in the
winter or if you live near the ocean,
you should hose off the undercarriage
at least once a month to minimize cor-
rosion.
High pressure water or steam is effec-
tive for cleaning the vehicle’s underside
and wheel housings. Pay particular
attention to these areas as it is difficult
to see all the mud and dirt. It will do
more harm than good to simply wet the
mud and debris without removing. The
lower edge of doors, rocker panels and
frame members have drain holes which
should not be allowed to clog with dirt
as trapped water in these areas can
cause corrosion.
Wash the underside of the vehicle thor-
oughly when winter is over.
See “Washing and waxing your Scion” for
more tips.
Check the condition of your vehicle’s
paint and trim. If you find any chips or
scratches in the paint, touch them up im-
mediately to prevent corrosion from start-
ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair.

Vinyl interior
The vinyl upholstery may be easily
cleaned with a mild soap or detergent
and water.
First vacuum over the upholstery to re-
move loose dirt. Then, using a sponge or
soft cloth, apply the soap solution to the
vinyl. After allowing it to soak in for a few
minutes to loosen the dirt, remove the dirt
and wipe off the soap with a clean damp
cloth. If all the dirt do not come off, re-
peat the procedure. Commercial foaming−
type vinyl cleaners are also available
which work well. Follow the manufacturer ’s
instructions.
NOTICE
Do not use solvent, thinner, gasoline
or window cleaner on the interior.
Carpets
Use a good foamtype shampoo to
clean the carpets.
Begin by vacuuming thoroughly to remove
as much dirt as possible. Several types of
foam cleaners are available; some are in
aerosol cans and others are powders or
liquids which you mix with water to pro-
duce a foam. To shampoo the carpets,
use a sponge or brush to apply the foam.
Rub in overlapping circles.
Do not apply water—the best results are
obtained by keeping the carpet as dry as
possible. Read the shampoo instructions
and follow them closely.
Seat belts
The seat belts may be cleaned with
mild soap and water or with lukewarm
water.
Use a cloth or sponge. As you are clean-
ing, check the belts for excessive wear,
fraying, or cuts.
NOTICE
 Do not use dye or bleach on the
belts—it may weaken them.
 Do not use the belts until they be-
come dry.
Windows
Do not use glass cleaner to clean the
inside of the rear window, as this may
cause damage to the rear window de-
fogger heater wires. Use a cloth damp-
ened with lukewarm water to gently
wipe the window clean. Wipe the win-
dow in strokes running parallel to the
heater wires.
NOTICE
When cleaning the inside of the rear
window, be careful not to scratch or
damage the heater wires.
Air conditioning control panel, instru-
ment panel, console panel, and
switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly wipe off dirt.

235
Tire inflation pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See page 250 for additional
information.
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See page
252 for additional information. When
checking the tires, make sure no nuts
are missing, and check the nuts for
looseness. Tighten them if necessary.
Tire rotation
Rotate the tires
according to the
maintenance schedule. (For sched-
uled maintenance information, please
refer to the “Scheduled Maintenance
Guide” or “Owner ’s Manual Supple-
ment”.) See page 254 for additional
information.
Be on the alert for changes in perfor-
mance, sounds, and visual tip −offs that
indicate service is needed. Some impor-
tant clues are as follows:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (however,
water dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flat −looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving
straight on a level road
Strange noises related to suspension
movement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continually
higher than normal If you notice any of these clues, take your
vehicle to your Scion dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.
Does your vehicle need
repairing?

254 Scion recommends all four tires, or
at least both of the front or rear
tires be replaced at a time as a set.
See “If you have a flat tire” on page
206 for tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect ve-
hicle handling and tire life. Wheels
can get out of balance with regular
use and should therefore be balanced
occasionally.
When replacing a tubeless tire, the
air valve should also be replaced
w i t h a new on e.
Rotating tires
To equalize the wear and help ex-
tend tire life, Scion recommends
that you rotate your tires accord-
ing to the maintenance schedule.
(For scheduled maintenance infor-
mation, please refer to the “Sched-
uled Maintenance Guide” or “Own-
er’s Manual Supplement”.)
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See “If you have a flat tire” on page
206 for tire change procedure. When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire infla-
tion pressure, improper wheel align-
ment, out
−of −balance wheels, or se-
vere braking.
CAUTION
Do not include a compact spare
tire when rotating the tires. It is
designed for temporary use only.
The tire pressure warning system
must be initialized when rotating tires,
in case that specified tire inflation
pressure is different between front
and rear.
