flat tire TOYOTA 4RUNNER 1999 Owners Manual

4RUNNER ()193
Never tow a trailer without using a
safety chain securely attached 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 trail-
er manufacturer in respect to the total
trailer weight.
TRAILER LIGHTS Trailer lights must comply with federal,
state/provincial and local regulations.
See your local recreational vehicle
dealer or rental agency for the correct
type of wiring and relays for your trail-
er. Check for correct operation of the
turn signals and stop lights each time
you hitch up. Direct splicing may dam-
age your vehicle's electrical system
and cause a malfunction 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 com-
ponent (engine, transmission, differen-
tial, 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 informa-
tion, please refer to the scheduled
maintenance information in the ºSched-
uled Maintenance Guideº or ºOwner 's
Manual Supplementº.
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 securely
loaded so that it cannot shift.
Check that your rear view mirrors con-
form to any applicable federal, state/
provincial or local regulation. If not,
install the rear view mirrors required
for towing purpose.

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 specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect 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, causing
greater fuel consumption.
Avoid lengthy warm- up idling. Once
the engine is running smoothly, begin
drivingÐbut gently. Remember, howev-
er, that on cold winter 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 dis-
tance from other vehicles to avoid sud-
den 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 econo-
my.
Maintain a moderate speed on high-ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
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 tuned- up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease,brakes not adjusted, etc. all
lower engine performance and contrib-
ute 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 informa-
tion, please refer to the separate
ºScheduled Maintenance Guideº or
ºOwner 's Manual Supplementº).
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.

Part 4
IN CASE OF AN
EMERGENCY
If your vehicle will not start
If your engine stalls while
driving
If your vehicle overheats
If you have a flat tire
If your vehicle needs to be
towed
If you cannot shift automatic
transmission selector lever
If you lose your keys
If you lose your wireless
remote control transmitter
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in ºHow to start the engineº
in Part 3 and that you have sufficient fuel.
If your vehicle is equipped with the engine
immobiliser system, also check whether
the other keys will start the engine. If
they work, your key may be broken. Have
the key checked at your Toyota dealer. If
none of your keys work, the system is
possibly broken. Call your Toyota dealer.
(See ºKeys (with engine immobiliser sys-
tem)º in Chapter 1- 2.)
If the engine is not turning over or is
turning over too slowlyÐ
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the battery
is discharged. You may try jump start-
ing. See º(c) Jump startingº for further
instructions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair
shop.NOTICE
Do not pull- or push- start the ve- hicle. It may damage the vehicle orcause a collision when the engine starts. Also the three- way catalytic
converter may overheat and become afire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. Check that all the push- on connectors are tight. (For example, connections at
the spark plugs, ignition coil and/or dis-
tributor)
2. If the connectors are O.K., the engine may be flooded because of repeated
cranking. See º(b) Starting a flooded
engineº for further instructions.

If you have a flat tireÐ
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the
road to a safe place well away from
the traffic. Avoid stopping 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 (automatic) or
reverse (manual).
4. Have everyone get out of the vehicle on the side away from traffic.
5. Read the following instructions thor- oughly.
CAUTION
When jacking, be sure to observe the
following to reduce the possibility of
personal injury: Follow jacking instructions.
Do not put any part of your body
under the vehicle supported by the
jack. Personal injury may occur.
Do not start or run the engine while
your vehicle is supported by the
jack.
Stop the vehicle on a level firm
ground, firmly set the parking brake
and put the transmission in ºPº
(automatic) or reverse (manual).
Block the wheel diagonally opposite
to the one being changed if neces-
sary.
Make sure to set the jack properly
in the jack point. Raising the ve-
hicle with jack improperly posi-
tioned will damage the vehicle or
may allow the vehicle to fall off the
jack and cause personal injury.
Never get under the vehicle when
the vehicle is supported by the jack
alone.
Use the jack only for lifting your
vehicle during wheel changing.
Do not raise the vehicle with some-
one in the vehicle.
When raising the vehicle, do not
put an object on or under the jack.
Raise the vehicle only high enough
to remove and change the tire.NOTICE
Do not continue driving with a de-
flated tire. Driving even a short dis-tance can damage a tire beyond re- pair.

ÐBlocking the wheel
2. Block the wheel diagonally opposite
the flat tire to keep the vehicle from
rolling when it is j acked up.
When blocking the wheel, place a wheel
block from the front for the front wheels
or from the rear for the rear wheels. ÐRemoving wheel ornamentSteel wheels
Aluminum wheels3. Remove the wheel ornament.
Pry off the wheel ornament, using the
beveled end of the wheel nut wrench as
shown.
CAUTION
Do not try to pull off the ornament by
hand. Take due care in handling the
ornament to avoid unexpected person-
al injury.

ÐLoosening wheel nuts
4. Loosen all the wheel nuts.
Always loosen the wheel nuts before rais-
ing the vehicle.
The nuts turn counterclockwise to loosen.
To get maximum leverage, fit the wrench
to the nut so that the handle is on the
right side, as shown above. Grab the
wrench near the end of the handle and
pull up on the handle. Be careful that the
wrench does not slip off the nut.
Do not remove the nuts yetÐjust unscrew
them about one- half turn. ÐPositioning the jack
Front Rear
5. Position the jack at the correct jack point as shown.
Make sure the jack is positioned on a
level and solid place. ÐRaising your vehicle
6. After making sure that no one is in
the vehicle, raise it high enough so
that the spare tire can be installed.
Remember you will need more ground
clearance when putting on the spare tire
than when removing the flat tire.
To raise the vehicle, insert the jack handle
extension in to the jack (it is a loose fit)
and turn it clockwise with the handle,
making sure the handle remains firmly
fitted onto the jack handle extension. As
the jack touches the vehicle and begins
to fit, double- check that it is properly
positioned.

CAUTION
Never get under the vehicle when the
vehicle is supported by the jack
alone.
ÐChanging wheels
7. Remove the wheel nuts and change tires.
Lift the flat tire straight off and put it
aside.
Roll the spare wheel into position and
align the holes in the wheel with the bolts.
Then lift up the wheel and get at least the
top bolt started through its hole. Wiggle
the tire and press it back over the other
bolts.Before putting on wheels, remove any cor-
rosion on the mounting surfaces with a
wire brush or such. Installation of wheels
without good metal- to- metal contact at the
mounting surface can cause wheel nuts to
loosen and eventually cause a wheel to
come off while driving. Therefore after the
first 1600 km (1000 miles), check to see
that the wheel nuts are tight.

ÐReinstalling wheel ornament
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 orna-
ment to avoid unexpected personal
injury.
ÐAfter changing wheels
11. Check the air pressure of the re- placed tire.
Adjust the air pressure to the specification
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 inflation
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. Restow all the tools, jack and flat tire securely.
As soon after changing wheels as pos-
sible, 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 securely
in place in their storage location to
reduce the possibility of personal in-
jury during a collision or s udden
braking.

Automatic transmission ºParkº mecha- nism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your
vehicle is held securely with the selector
lever in ºPº position and all brakes re-
leased.
IN THE ENGINE COMPARTMENT
Items listed below should be checked
from time to time, e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7- 3 for additional in-
formation.
Engine coolant level
Make sure the coolant level is between
the ºFULLº and ºLOWº lines on the
see- through reservoir when the engine is
cold. See Chapter 7- 2 for additional in-
formation.
Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower lev-
el lines on the case. Add only distilled
water when replenishing. See Chapter 7- 3
for additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See Chapter 7- 2 for additional information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See Chapter 7- 2 for addi-
tional information.
Power steering fluid level
Check the level through the reservoir. The
level should be in the ºHOTº or ºCOLDº
range depending on the fluid temperature.
See Chapter 7- 2 for additional information.
Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.)
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 leak under the vehicle (however, wa-
ter 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
Does your vehicle need
repairing?

c. Reinstall the filler cap.
d. Remove the filler cap again and look
at the fluid level. If the fluid is cold, the
level should be in the ºCOLDº range on
the dipstick. Similarly, if it is hot, the fluid
level should be in the ºHOTº range. If the
level is at the low side of either range,
add automatic transmission fluidDEXRON
II or III to bring the level within
the range.
e. After replacing the filler cap, visually
check the steering box case, vane pump
and hose connections for leaks or dam-age.
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.
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 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 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 pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire pressures that
are even just a few pounds off can
degrade handling and ride.
Do not bleed or reduce tire pressure
after driving. It is normal for the tire
pressure to be higher after driving.
Never exceed the vehicle capacity
weight. The passenger and luggage
weight should be located so that the
vehicle is balanced.
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.
