ECO TOYOTA HIGHLANDER 2002 XU20 / 1.G Owners Manual

’02 HIGHLANDER_U (L/O 0108)
2402002 MY HIGHLANDER_U (OM48429U)
Your Toyota vehicle has been designed for
fewer maintenance requirements with long-
er service intervals to save both your time
and money. However, each regular mainte-
nance, as well as daytoday care, is
more important than ever before to ensure
smooth, troublefree, safe, and economical
drivings.
It is the owner ’s responsibility to make
sure the specified maintenance, including
general maintenance service, is performed.
Note that both the new vehicle and emis-
sion control system warranties specify that
proper maintenance and care must be per-
formed. See “Owner ’s Warranty Informa-
tion Booklet” or “Owner ’s Manual Supple-
ment” for complete warranty information.
General maintenance
General maintenance items are those day
today care practices that are important to
your vehicle for proper operation. It is the
owner ’s responsibility to ensure that the
general maintenance items are performed
regularly.
These checks or inspections can be done
either by yourself or a qualified technician,
or if you prefer, your Toyota dealer will be
pleased to do them at a nominal cost. Scheduled maintenance
The scheduled maintenance items listed in
the “Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement” are those
required to be serviced at regular inter-
vals.
For details of your maintenance schedule,
read the “Scheduled Maintenance Guide”
or “Owner ’s Manual Supplement”.
It is recommended that any replacement
parts used for maintenance or for the
repair of the emission control system
be Toyota supplied.
The owner may elect to use nonToyota
supplied parts for replacement pur-
poses without invalidating the emission
control system warranty. However, use
of replacement parts which are not of
equivalent quality may impair the effec-
tiveness of the emission control sys-
tems.
You may also elect to have mainte-
nance, replacement, or repair of the
emission control devices and system
performed by any automotive repair es-
tablishment or individual without invali-
dating this warranty. See “Owner’s War-
ranty Information Booklet” or “Owner’s
Manual Supplement” for complete war-
ranty information.Where to go for service?
Toyota technicians are welltrained spe-
cialists and are kept up to date with the
latest service information through technical
bulletins, service tips, and indealership
training programs. They learn to work on
Toyotas before they work on your vehicle,
rather than while they are working on it.
You can be confident that your Toyota
dealer ’s service department performs the
best job to meet the maintenance require-
ments on your vehicle—reliably and eco-
nomically.
Your copy of the repair order is proof that
all required maintenance has been per-
formed for warranty coverage. And if any
problems should arise with your vehicle
while under warranty, your Toyota dealer
will promptly take care of it. Again, be
sure to keep a copy of the repair order
for any service performed on your Toyota.
What about doityourself maintenance?
Many of the maintenance items are easy
to do yourself if you have a little mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form them are presented on page 245 in
Section 7.

If you are a skilled doityourself mechan-
ic, the Toyota service manuals are recom-
mended. Please be aware that doityour-
self maintenance can affect your warranty
coverage. See “Owner ’s Warranty Informa-
tion Booklet” or “Owner ’s Manual Supple-
ment” for the details. Listed below are the general maintenance
items that should be performed as fre-
quently as specified. In addition to check-
ing the items listed, if you notice any
unusual noise, smell or vibration, you
should investigate the cause or take your
vehicle to your Toyota dealer or a quali-
fied service shop immediately. It is recom-
mended that any problem you notice be
brought to the attention of your dealer or
the qualified service shop for their advice.
CAUTION
Make these checks only where ade-
quate ventilation can be obtained if
you run the engine.
OUTSIDE THE VEHICLE
Items listed below should be performed
from time to time, unless otherwise
specified.
Tire pressure
Check the pressure with a gauge every
two weeks, or at least once a month. See
page 260 in Section 72 for additional
information.Tire surface and wheel nuts
Check the tires carefully for cuts, damage
or excessive wear. See page 261 in Sec-
tion 72 for additional information. When
checking the tires, make sure no nuts are
missing, and check the nuts for loose-
ness. Tighten them if necessary.
Tire rotation
Rotate the tires according to the
maintenance schedule. (For scheduled
maintenance information, please refer to
the “Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.) See page
262 in Section 72 for additional
information.
Fluid leaks
Check underneath for leaking fuel, oil, wa-
ter or other fluid after the vehicle has
been parked for a while. If you smell fuel
fumes or notice any leak, have the cause
found and corrected immediately.
Doors and engine hood
Check that all side doors and back door
operate smoothly and all latches lock se-
curely. Make sure the engine hood sec-
ondary latch secures the hood from open-
ing when the primary latch is released.

ENGINE OIL SELECTION
Use API grade SJ “EnergyConserving”,
SL “EnergyConserving” or ILSAC
multigrade engine oil.
Recommended viscosity (SAE):
5W-30 Preferred
Temperature range anticipated before
next oil change
SAE 5W30 is the best choice for your
vehicle, for good fuel economy and
good starting in cold weather.
If you use SAE 10W30 engine oil in
extremely low temperatures, the engine
may become difficult to start, so SAE
5W30 engine oil is recommended.
API service symbol
ILSAC certification mark
Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SL. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W30. “Energy
Conserving” shown in the lower portion,
indicates that the oil has fuelsaving ca-
pabilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.

Look at the seethrough coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the “F” and “L” lines on the reservoir.
If the level is low, add ethyleneglycol
type coolant for a proper corrosion
protection of aluminum components.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the “L” line, add
coolant. Bring the level up to the “F” line.
Always use ethyleneglycol type coolant
for a proper corrosion protection of alumi-
num components. See information in the
next column.
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 your Toyota
dealer 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 cooling system. Your coolant
must contain ethyleneglycol type coolant
for a proper corrosion protection of your
engine that contains aluminum compo-
nents. Use “TOYOTA Long Life Coolant”
or equivalent.
In addition to preventing freezing and sub-
sequent damage to the engine, this type
of coolant will also prevent corrosion. Fur-
ther supplemental inhibitors or additives
are neither needed nor recommended.
Read the coolant container for information
on freeze protection. Follow the manufac-
turer’s directions for how much to mix
with plain water (preferably demineralized
water or distilled water). The total c apacity
of the cooling system is given on page
280 in Section 8. We recommend to use 50% solution for
your Toyota, to provide protection down to
about 35
C (31 F). When it is extreme-
ly cold, to provide protection down to
about 50 C (58 F), 60% solution is rec-
ommended. Do not use more than 70%
solution for better coolant performance.NOTICE
Do not use alcohol type antifreeze or
plain water alone.

Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (80 C or 175 F). You may also check
the level when the fluid is cold (about
room temperature, 10 C—30 C or
50 F—85 F) if the engine has not been
run for about five hours. Clean all dirt from outside of the reservoir
tank and look at the fluid level. If the fluid
is cold, the level should be in the “COLD”
range. Similarly, if it is hot, the fluid level
should be in the “HOT” range. If the level
is at the low side of either range, add
automatic transmission fluid DEXRON
II or
III to bring the level within the range.
To remove the reservoir cap, turn it coun-
terclockwise and lift up. To reinstall it,
turn it clockwise. After replacing the reser-
voir cap, visually check the steering box
case, vane pump and hose connections
for leaks or damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.
The air conditioning filter is behind the
glove box.
The air conditioning filter may clog af-
ter long use. The filter may need to be
replaced if the air flow of the air condi-
tioning and heater experiences extreme
reductions in operating efficiency, or if
the windows become to fog up easily.
To maintain the air conditioning efficiency,
inspect and replace the air conditioning
filter according to the maintenance sched-
ule. (For scheduled maintenance informa-
tion, please refer to the “Scheduled Main-
tenance Guide” or “Owner ’s Manual
Supplement”.)

5. Remove the filter from the filter
case.
6. Inspect the filter on the surface.
If it is dirty, it should be replaced.
INFORMATION
The air filter should be installed prop-
erly in position. The use of air condi-
tioning with the air filter removed
may cause deteriorated dustproof per-
formance and then affect air condi-
tioning performance.
Keep your tire pressures at the proper
level.
The recommended cold tire pressures, tire
size and the vehicle capacity weight are
given on page 278 and page 281 in Sec-
tion 8. They are also on the tire pressure
label as shown.
You should check the tire pressures every
two weeks, or at least once a month. And
do not forget the spare! Incorrect tire pressure can reduce tire
life and make your vehicle less safe to
drive.
Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts from
overheated tires. Also, low tire pressure
can cause poor sealing of the tire bead.
If the tire pressure is excessively low,
there is the possibility of w
heel deforma-
tion and/or tire separation.
High tire pressure produces a harsh ride,
handling problems, excessive wear at the
center of the tire tread, and a greater
possibility of tire damage from road haz-
ards.
If a tire frequently needs ref illing, have it
checked by your Toyota dealer.
The following instructions for checking
tire pressure should be observed:
The 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 pressure
reading.
Checking tire pressure

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
Do not mix radial, bias belted, or
biasply tires on your vehicle. It
can cause dangerous handling char-
acteristics, resulting in loss of con-
trol.
Do not use tire or wheels other
than the manufacturer ’s recom-
mended size.
NOTICE
Fourwheel drive models:
Do not use tires of different brands,
sizes and constructions. This may
damage the drive system.
Toyota recommends all four tires, or at
least both front or rear tires be re-
placed as a set.
See “If you have a flat tire” on page 216
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.
To equalize tire wear and help extend
tire life, Toyota recommends that you
rotate your tires according to the main-
tenance schedule. (For scheduled main-
tenance information, please refer to the
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.) Howev-
er, the most appropriate timing for tire
rotation may vary according to your
driving habits and road surface condi-
tions.
See “If you have a flat tire” on page 216
in Section 4 for tire change procedure.
Rotating tires

’02 HIGHLANDER_U (L/O 0108)
2632002 MY HIGHLANDER_U (OM48429U)
When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, outofbalance
wheels, or severe braking. 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 the same
size, construction and load capacity as
the original tires on your Toyota.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
NOTICE
Fourwheel drive models:
Do not use tires of different brands,
sizes and constructions. This may
damage the drive system.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front w
heels
only can lead to an excessive difference
in road grip capability between 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.
Mark the direction of rotation and be sure
to install them in the same direction when
replacing.
CAUTION
Do not drive with the snow tires
incorrectly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.

Side chain
Cross chain
TIRE CHAIN SELECTION
Use the tire chains of correct size.
Use the following type chains. mm (in.)
A Diameter of side chain 3 (0.12)
B Width of side chain 10 (0.39)
C Length of side chain 30 (1.18)
D Diameter of cross chain 4 (0.16)
E Width of cross chain 14 (0.55)
F Length of cross chain 25 (0.98)
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check them
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 front tires as
tightly as possible. Do not use tire
chains on the 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.
CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or lockedwheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering the curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.

The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the ignition switch and
light switch are off. Use bulbs with the
wattage ratings given in the table.
CAUTION
To prevent yourself from burning,
do not replace the light bulbs while
they are hot.
Halogen bulbs have pressurized gas
inside and require special handling.
They can burst or shatter if
scratched or dropped. Hold a bulb
only by its plastic or metal case.
Do not touch the glass part of a
bulb with bare hands.
NOTICE
Only use a bulb of the listed type.
The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens becomes wet in the rain or
in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lens, just like the
windshield fogged up in the rain. However,
if there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your
Toyota dealer. Light bulbsBulb
