1998 TOYOTA 4RUNNER tire pressure

4RUNNER (1998)
A safety chain must always be
used between the towing vehicle
and the trailer. Leave sufficient
slack in the chain for turns. The
chain should cross under the
trailer tongue to prevent the
tongue from dropping to the
ground in case it becomes dam-
aged or separated. For correct
safety chain procedures, follow
the hitch or trailer manufactur-
er 's recommendations.
CAUTION
If the total trailer weight ex-
ceeds 453 kg (1000 lb.), trailer
brakes are required .
Never tap into your vehicle's
hydraulic system as it would
lower its braking effectiveness .
Never tow a trailer without us-
ing a safety chain securely atta-
ched to both the trailer and the
vehicle. If damage occurs to the
coupling unit or hitch ball,
there is danger of the trailer
wandering over into another
lane.
TIRES
Ensure that your vehicle's tires are
properly inflated. See Chapter 7- 2
for instructions.
The trailer tires should be inflated
to the pressure recommended by
the trailer manufacturer in respect
to the total trailer weight.
TRAILER LIGHTS Trailer lights must comply with fed-
eral, state/provincial and local re-
gulations. See your local recre-
ational vehicle dealer or rental
agency for the correct type of wir-
ing and relays for your trailer.
Check for correct operation of the
turn signals and stop lights each
time you hitch up. Direct splicing
may damage your vehicle's electri-
cal system and cause a malfunc-
tion of your lights.
BREAK- IN SCHEDULE Toyota recommends that you do
not tow a trailer with a new vehicle
or a vehicle with any new power
train component (engine, transmis-
sion, differential, wheel bearing,
etc.) for the first 800 km (500
miles) of driving. MAINTENANCE
If you tow a trailer, your vehicle
will require more frequent
maintenance due to the additional
load. For this information, please
refer to the scheduled maintenance
information in the ºOwner 's Manual
Supplement/Maintenance Scheduleº.
Retighten all fixing bolts of the
towing ball and bracket after
approximately 1000 km (600 miles)
of trailer driving.
PRE- TOWING SAFETY CHECK
Check that your vehicle remains
level when a loaded or unloaded
trailer is hitched. Do not drive if
the vehicle has an abnormal nose-
up or nose- down condition, and
check for improper tongue load,
overload, worn suspension or other
possible causes.
Make sure the trailer cargo is se-
curely loaded so that it cannot
shift.
Check that your rear view mirrors
conform to any applicable federal,
state/provincial or local regulation.
If not, install the rear view mirrors
required for towing purpose.

Slow down and downshift be-
fore descending steep or long
downhill grades. Do not make
sudden downshifts.
Avoid holding the brake pedal
down too long or too frequent-
ly. This could cause the brakes
to overheat and result in re-
duced braking efficiency.Getting more kilometers/mileage from
a liter/gallon of fuel is easyÐjust take
it easy. It will help make your vehicle
last longer, too. Here are some specif-
ic tips on how to save money on both
fuel and repairs:
Keep your tires inflated at the
correct pressure. Underinflation
causes tire wear and wastes fuel.
See Chapter 7- 2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts
a heavier load on the engine, caus-
ing greater fuel consumption.
Avoid lengthy warm- up idling.
Once the engine is running smooth-
ly, begin drivingÐbut gently. Re-
member, however, that on cold win-
ter days this may take a little
longer.
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into
high gear as quickly as possible.
Avoid long engine idling. If you
have a long wait and you are not
in traffic, it is better to turn off the
engine and start again later.
Avoid engine lug or overrevving.
Use a gear position suitable for the
road on which you are travelling.
Avoid continuous speeding up
and slowing down. Stop- and- go
driving wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace.
Try to time the traffic signals so
you only need to stop as little as
possible or take advantage of
through streets to avoid traffic
lights. Keep a proper distance from
other vehicles to avoid sudden
braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic
jams whenever possible.
Do not rest your foot on the
clutch or brake pedal. This
causes needless wear, overheating
and poor fuel economy.
Maintain a moderate speed on
highways. The faster you drive,
the greater the fuel consumption.
By reducing your speed, you will
cut down on fuel consumption.
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.

3. Visually check to see if the engine drive belt (fan belt) is broken or
loose. Look for obvious coolant
leaks from the radiator, 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 engine drive belt is brokenor the coolant is leaking, stop the
engine immediately. Call a Toyota
dealer for assistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you
may help the engine cool down
more quickly by running it at about
1500 rpm for a few minutes with
the accelerator pedal lightly de-
pressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir
while the engine is running. Fill it
about half full.
CAUTION
Do not attempt to remove the ra-
diator cap when the engine and
radiator are hot. Serious injury
could result from scalding hot
fluid and steam blown out under
pressure.
7. After the engine coolant tempera-ture has cooled to normal, again
check the coolant level in the res-
ervoir. If necessary, bring it up to
half full again. Serious coolant loss
indicates a leak in the system. You
should have it checked as soon as
possible at your Toyota dealer. If you have a flat tireÐ
1. Reduce your speed gradually, keep- ing a straight line. Move cautiously
off the road to a safe place well
away from the traffic. Avoid stop-
ping on the center divider of a
highway. Park on a level spot with
firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in ºPº (auto-
matic) or reverse (manual).
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.
CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury: Follow jacking instructions.
Do not start or run the engine
while your vehicle is supported
by the jack.

10. Reinstall the wheel ornament.
Put the wheel ornament into position
and then tap it firmly with the side or
heel of your hand to snap it into
place.
CAUTION
Take due care in handling the or-
nament to avoid unexpected per-
sonal injury.
ÐAfter changing wheels
11. Check the air pressure of the re- placed tire.
Adjust the air pressure to the specifi-
cation designated in Part 8. If the
pressure is lower, drive slowly to the
nearest service station and fill to the
correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into the valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
12. Restore all the tools, jack and flat tire securely. As soon as possible after changing
wheels, tighten the wheel nuts to the
torque specified in Part 8 with a
torque wrench and have a technician
repair the flat tire.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.

Where to go for service?
Toyota technicians are well- trained
specialists and are kept up to date
with the latest service information
through technical bulletins, service
tips, and in- dealership training pro-
grams. 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
requirements on your vehicleÐreliably
and economically.
Your copy of the repair order is proof
that all required maintenance has
been performed 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 ser-
vice performed on your Toyota.
What about do- it- yourself mainte- nance?
Many of the maintenance items are
easy to do yourself if you have a little
mechanical ab ility and a few basic au-
tomotive tools. Simple instructions for
how to perform them are presented in
Part 7. If you are a skilled do- it- yourself me-
chanic, the Toyota service manuals
are recommended. Please be aware
that do- it- yourself maintanance can
affect your warranty coverage. See
ºOwner 's Guideº, ºOwner 's Manual
Supplementº or ºWarranty Bookletº for
the details.
General maintenance
Listed below are the general mainte-
nance items that should be performed
as frequently as specified. In addition
to checking 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 qualified service
shop immediately. It is recommended
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 ad-
equate ventilation can be obtained
if you run the engine.
OUTSIDE THE VEHICLE
Items listed below should be per-
formed from time to time, unless
otherwise specified.
Tire pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See Chapter 7- 2 for additional
information.

Checking tire pressure
Keep your tire pressures at the
proper level.
The recommended cold tire pressures,
tire size and the cargo weight rating
are given in Part 8.
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
economy, and the possib ility of blow-
outs 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 possi-
bility of w heel deformation 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 dam-
age from road hazards.
If a tire frequently needs ref illing,
have it checked by your Toyota deal-
er. The following instructions for
checking tire pressure should be
observed:
The pressure should be checked
only when the tires are cold. If
your vehicle has been packed 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 pressuregauge. The appearance of a tire
can be misleading. Besides, tire
pressures that are even just a few
pounds off can degrade 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 capac-
ity weight. The passenger and lug-
gage weight should be located so
that the vehicle is balanced.
Be sure to reinstall the tire infla-
tion 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 and replacing tires
