Low level Full level
Add oil O.K. Too full
With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick.
1. To get a correct reading, the vehicle
should be on level ground. After warm-
ing up the engine and turning it off,
wait more than five minutes for the oil
to drain back into the bottom of the
engine.
2. Pull the dipstick out, hold a rag under
the end and wipe it clean.
3. Reinsert the dipstick—push it in as far
as it will go, or the reading will not be
correct.
4. Pull the dipstick out and look at the oil
level while holding a rag under the
end.
NOTICE
Be careful not to drop engine oil on
the vehicle components.
If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler capand add engine
oil in small quantities at a time, checking
the dipstick. We recommend that you use
a funnel when adding oil.The approximate quantity of oil needed to
raise the level between low and full on the
dipstick is indicated as follows:
1.9L(2.0qt.,1.7Imp.qt.)
For the engine oil capacity, see “Service
specifications” on page 224 in Section 8.
When the level reaches within the correct
range, install the filler cap hand−tight.
NOTICE
zBe careful not to spill engine oil on
the vehicle components.
zAvoid overfilling, or the engine
could be damaged.
zCheck the oil level on the dipstick
once again after adding the oil.

ENGINE OIL SELECTION
“Toyota Genuine Motor Oil” is used in
your Toyota vehicle. Toyota recommends
the use of approved “Toyota Genuine
Motor Oil”. Another motor oil of matching
quality can also be used.
Oil grade:
ACEA C2
NOTICE
Using engine oil other than ACEA C2
may damage the catalytic converter.
Recommended viscosity (SAE):
Temperature range anticipated before
next oil change
Preferred
SAE 0W−30 is filled into your Toyota
vehicle at manufacturing, and the best
choice for good fuel economy and good
starting in cold weather.Oil viscosity (0W−30 is explained here as
an example):
The0Win0W−30 indicates the character-
istic of the oil which allows cold startabil-
ity. Oils with a lower value before the W
allow for easier starting of the engine in
cold weather.
The30in0W−30 indicates the viscosity
characteristic of the oil when the oil is at
high temperature. An oil with a higher vis-
cosity (one with a higher value) may be
better suited if the vehicle is operated at
high speeds, or under extreme load condi-
tions.

198DO−IT−YOURSELF MAINTENANCE: Engine and Chassis
To ensure excellent lubrication perfor-
mance for your engine, Toyota recom-
mends the use of “Toyota Genuine Motor
Oil”, which has been specifically tested
and approved for all Toyota engines.
Please contact any authorized Toyota
dealer or repairer for further details about
“Toyota Genuine Motor Oil”. Other motor
oils of matching quality also be used.Look at the see−through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the “FULL” and “LOW” lines on the
reservoir. If the level is low, add the
coolant. (For the coolant type, see
“Coolant type selection” described be-
low.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the “LOW” line, add
coolant. Bring the level up to the “FULL”
line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional,
test the cap pressure and check for leaks
in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.

Coolant type selection
Use of improper coolants may damage
your engine coolingsystem.
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.)
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about−35_C(−31_F).
NOTICE
Do not use plain water alone.
Toyota recommends “Toyota Super Long
Life Coolant”, which has been tested to
ensure that it will not cause corrosion nor
result in malfunction of your engine
coolant system with proper usage. “Toyota
Super Long Life Coolant” is formulated
with long−life hybrid organic acid
technology and has been specifically
designed to avoid engine coolingsystem
malfunction on Toyota vehicles.
Please contact any authorized Toyota
dealer or repairer for further details.

If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional.
CAUTION
To prevent burning yourself, be care-
ful not to touch the radiator, con-
denser and intercooler when the en-
gine is hot.
NOTICE
To prevent damage to the radiator,
condenser and intercooler, do not per-
formtheworkbyyourself.
When the fuel filter warning light
comes on, the water in the fuel filter
must be drained immediately.
Place a small tray under the drain plug to
catch the water.
1. Turn the drain plug about 2—2−1/2
turns, as shown above. (Loosening
more than this will cause water oozing
from around the drain plug.)
2. Operate the priming pump until fuel be-
gins to run out.
After draining, retighten the drain plug. Do
not use a tool.

Keep your tire inflation pressures at the
proper level.
The recommended cold tire inflation pres-
sures and tire sizes are given on page
226 in Section 8.
You should check the tire inflation pres-
sure every two weeks, or at least once a
month. And do not forget the spare!
Incorrect tire inflation pressure may waste
fuel, reduce the comfort of driving, reduce
tire life and make your vehicle less safe
to drive.
If a tire frequently needsrefilling,have it
checked by any authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional.
The following instructions for checking
tire inflation pressure should be ob-
served:
DThe pressure should be checked only
when the tires are cold.If your ve-
hicle has been parked for at least 3
hours and has not been driven for
more than 1.5 km or 1 mile since, you
will get an accurate cold tire inflation
pressure reading.
DAlways use a tire pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire inflation pressur-
es that are even just a few pounds off
can degrade ride and handling.
DDo not bleed or reduce tire inflation
pressure after driving.It is normal for
the tire inflation pressure to be higher
after driving.
DBe sure to reinstall the tire valve
caps.Without the valve caps, dirt or
moisture could get into the valve core
and cause air leakage. If the caps
have been lost, have new ones put on
as soon as possible.
CAUTION
Keep your tires properly inflated.
Otherwise, the following conditions
may occur and cause an accident re-
sulting in death or serious injuries.
Low tire pressure (underinflation)—
DExcessive wear
DUneven wear
DPoor handling
DPossibility of blowouts from an
overheated tire
DPoor sealing of the tire bead
DWheel deformation and/or tire sepa-
ration
DA greater possibility of tire damage
from road hazards
High tire pressure (overinflation)—
DPoor handling
DExcessive wear
DUneven wear
DA greater possibility of tire damage
from road hazards

Treadwear indicator
CHECKING YOUR TIRES
Check the tire’s tread for treadwear in-
dicators. If the indicators show, replace
the tires. The location of treadwear in-
dicators is shown by the “TWI” or “
”
marks, etc., molded on the sidewall of
each tire.
The tires on your Toyota have built−in
treadwear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If
you can see the indicators in two or more
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16 in.).
If you have tire damage such as cuts,
splits, cracks deep enough to expose
the fabric, or bulges indicating internal
damage, the tire should be replaced.
If a tire often goes flat or cannot be prop-
erly repaired due to the size or location
of a cut or other damage, it should be
replaced. If you are not sure, consult with
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional.
If air loss occurs while driving, do not
continue driving. Driving even a short dis-
tance can damage a tire beyond repair.Any tires which are over 6 years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use a tire of the
same size and construction, and the
same or greater load capacity as the
originally installed tires.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
and clearance between the body and tires
or snow chains.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
DDo not mix radial, bias belted, or
bias−ply tires on your vehicle, as
this may cause dangerous handling
characteristics resulting in loss of
control.
DDo not use tires other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
DDo not mix tires of different makes,
models or tread patterns, and do
not mix tires of remarkably different
treadwear. This may cause danger-
ous handling characteristics result-
ing in loss of control.

Never use second−hand tires on your
To y o t a .
Using tires whose previous history is un-
known is a risk.
Toyota recommends all four tires, or at
least both front or rear tires be re-
placed at a time as a set.
See “If you have a flat tire” on page 157
in Section 4 for tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
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 with a
new one.
With single rear tires
With double rear tires
To equalize tire wear and help extend
tire life, Toyota recommends that you
rotate your tires approximately every
10000 km (6000 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” on page 157
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.

204DO−IT−YOURSELF MAINTENANCE: Engine and Chassis
WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the originally installed tires.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
CAUTION
Do not use snow tires other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the rear wheels
only can lead to an excessive difference
in road grip capabilitybetween the front
and rear tires which could cause loss of
vehicle control.
When storing removed tires, you should
store them in a cool dry place.
In case of radial tires, mark the direction
of rotation and be sure to install them in
the same direction when replacing.
CAUTION
DDo not drive with the snow tires
incorrectly inflated.
DObserve permissible maximum
speed for your snow tires and the
legal speed limit.
TIRE CHAIN SELECTION
Use the tire chains of correct size.
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check the local
regulations before installing chains.
NOTICE
If the wrong combination of tire and
chain is used, the chains could dam-
age the vehicle body.
CHAIN INSTALLATION
Install the chains on the rear tires as
tightly as possible. Do not use tire
chains on the front tires. For vehicles
with dual rear wheels, install the chains
either on the outer rear tires or all four
rear tires. Retighten chains after driving
0.5—1.0 km (1/4—1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.
