1997 TOYOTA 4RUNNER fuel

200ENGINE OIL SELECTION Use API SH, Energy-Conserving IIº mul- tigrade engine oil or ILSAC multigrade en-
gine oil. Recommended viscosity (SAE):
SAE 5W-30 is the best choice for your
vehicle, for good fuel economy and
good starting in cold weather.
If you use SAE 10W-30 engine oil in
extremely low temperatures, the en-
gine may become difficult to start, so
SAE 5W-30 engine oil is recom-mended.
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 SH. The cen-
ter portion of the label shows the SAE vis-
cosity grade such as SAE 5W-30.
Energy-Conserving IIº shown in the low-
er portion, indicates that the oil has fuel-
saving capabilities. Oils marked Ener-
gy-Conserving IIº will have higher
fuel-saving capabilities than oil marked Energy-Conservingº.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee)Certification Mark is displayed on the front
of the container.

Keep your tire pressures at the proper level.
The recommended cold tire pressures, tire
size and the cargo weight are also giv-
en in Part 8.
You should check the tire pressures every two weeks, or at least once a month. And
don't 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 tread bead.
If the tire pressure is excessively low,
there is the possibility of wheel 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 pos-
sibility of tire damage from road hazards.
If a tire frequently needs refilling, have it
checked by your Toyota dealer. The following instructions for check-
ing tire pressure should be observed:
The pressure should be checked
only when the tires are cold. If your
vehicle 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.
Always use a tire pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire pressure that
are even just a few pounds off can de-
grade handling and ride.
Do not bleed or reduce tire pres-sure after driving. It is normal for the
tire pressure to be higher after driving.
Never exceed the vehicle capacityweight. The passenger and luggage
weight should be located so that the
vehicle is balacned.
Be sure to reinstall the tire inflation
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.
CHECKING YOUR TIRES Check the tire tread for the tread wear
indicators. If the indicators show, re-place the tires.
The tires on your Toyota have built-in tread wear 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 adja-
cent grooves, the tire should be replaced.
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.).
