4RUNNER (1998)
NOTICE
A large amount of unburned
gases flowing into the three- waycatalytic converter may cause itto overheat and create a fire haz-
ard. To prevent this and otherdamage, observe the followingprecautions:
Use only unleaded gasoline.
Do not drive with an extremely
low fuel level; running out offuel could cause the engine to misfire, creating an excessive
load on the three- way catalyticconverter.
Do not allow the engine to runat idle speed for more than 20 minutes.
Avoid racing the engine.
Do not push- start or pull- start
your vehicle.
Do not turn off the ignitionwhile the vehicle is moving.
Keep your engine in good run-
ning order. Malfunctions in theengine electrical system, elec-tronic ignition system/distribu-
tor ignition system or fuel sys-tems could cause an extremelyhigh three- way catalytic con-
verter temperature.
If the engine becomes difficultto start or stalls frequently,
take your vehicle in for acheck- up as soon as possible.
Remember, your Toyota dealer
knows your vehicle and itsthree- way catalytic converter
system best.
To ensure that the three- waycatalytic converter and the en-
tire emission control system op-erate properly, your vehiclemust receive the periodic in-
spections required by the Toyo-ta Maintenance Schedule. For scheduled maintenance informa-
tion, refer to the separateºOwner 's Manual Supplement/Maintenance Scheduleº.
Engine exhaust cautions
CAUTION
Avoid inhaling the engine ex-
haust. It contains carbon mon-
oxide, which is a colorless and
odorless gas. It can cause un-
consciousness or even death.
Make sure the exhaust system
has no holes or loose connec-
tions. The system should be
checked from time to time. If
you hit something, or notice a
change in the sound of the ex-
haust, have the system checked
immediately.
Do not run the engine in a ga-
rage or enclosed area except
for the time needed to drive the
vehicle in or out. The exhaust
gases cannot escape, making
this a particularly dangerous
situation.
Do not remain for a long time
in a parked vehicle with the en-
gine running. If it is unavoid-
able, however, do so only in an
unconfined area and adjust the
heating or cooling system to
force outside air into the ve-
hicle.

4RUNNER (1998)
Keep the back door and back
window closed while driving. An
open or unsealed back door and
back window, may cause ex-
haust gases to be drawn into
the vehicle. If you must drive
with the trunk lid open to ac-
commodate a large object, close
the windows, open all the
instrument panel vents and
have the heating or cooling sys-
tem deliver fresh air into the
vehicle by turning the fan to
high speed with the air intake
control set at the outside air
position.
To allow proper operation of
your vehicle's ventilation sys-
tem, keep the inlet grilles in
front of the windshield clear of
snow, leaves, or other obstruc-
tions.
If you smell exhaust fumes in
the vehicle, drive with the win-
dows open and the back door
and back window closed. Have
the cause immediately located
and corrected.FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions
of lubricating and cooling the inside of
the engine, and plays a major role in
maintaining the engine in proper work-
ing order.
ENGINE OIL CONSUMPTION
It is normal that an engine should
consume some engine oil during
normal engine operation. The
causes of oil consumption in a nor-
mal engine are as follows.
Oil is used to lubricate pistons,
piston rings and cylinders. A thin
film of oil is left on the cylinder
wall when a piston moves down-
wards in the cylinder. High nega-
tive pressure generated when the
vehicle is decelerating sucks some
of this oil into the combustion
chamber. This oil as well as some
part of the oil film left on the cylin-
der wall is burned by the high tem-
perature combustion gases during
the combustion process.
Oil is also used to lubricate the
stems of the intake valves. Some
of this oil is sucked into the com-
bustion chamber together with the
intake air and is burned along with
the fuel. High temperature exhaust
gases also burn the oil used to
lubricate the exhaust valve stems.
The amount of engine oil consumed
depends on the viscosity of the oil,
the quality of the oil and the condi-
tions the vehicle is driven under.
More oil is consumed by high- speed
driving and frequent acceleration and
deceleration.
A new engine consumes more oil,
since its pistons, piston rings and cyl-
inder walls have not become condi-
tioned.
When judging the amount of oil
consumption, note that the oil may
become diluted and make it difficult
to judge the true level accurately.
As an example, if a vehicle is used
for repeated short trips, and consumes
a normal amount of oil, the dipstick
may not show any drop in the oil
level at all, even after 1000 km (600
miles) or more. This is because the
oil is gradually becoming diluted with
fuel or moisture, making it appear that
the oil level has not changed.
Facts about engine oil
consumption

4RUNNER (1998)
The diluting ingredients evaporate out
when the vehicle is then driven at
high speeds, as on an expressway,
making it appear that oil is excessive-
ly consumed after driving at high
speeds.
IMPORTANCE OF ENGINE OIL LEV-
EL CHECK
One of the most important points in
proper vehicle maintenance is to keep
the engine oil at the optimum level so
that oil function will not be impaired.
Therefore, it is essential that the oil
level be checked regularly. Toyota rec-
ommends that the oil level be checked
every time you refuel the vehicle.
NOTICE
Failure to check the oil level regu-
larly could lead to serious enginetrouble due to insufficient oil.
For detailed information on oil level
check, see ºChecking the engine oil
levelº in Chapter 7- 2. Twin ground electrode spa

The brake pad wear limit indicators
on your disc brakes give a warning
noise when the brake pads are
worn to where replacement is re-
quired.
If you hear a squealing or scraping
noise while driving, have the brake
pads checked and replaced by your
Toyota dealer as soon as possible.
Expensive rotor damage can result if
the pads are not replaced when nec-
essary. Luggage stowage pr
ecau-
tions
When stowing luggage or cargo in the
vehicle, observe the following:
Put luggage or cargo in the lug-
gage compartment when at all pos-
sible. Be sure all items are se-
cured in place.
Be careful to keep the vehicle bal-
anced. Locating the weight as far
forward as possible helps maintain
balance.
For better fuel economy, do not
carry unneeded weight.
CAUTION
To prevent luggage or packages
from sliding forward during
braking, do not stack anything
in the luggage compartment
higher than the seatbacks. Keep
luggage or packages low, as
close to the floor as possible.
Never allow anyone to ride in
the luggage compartment. It is
not designed for passengers.
They should ride in their seats
with their seat belts properly
fastened. Otherwise, they are
much more likely to suffer seri-
ous bodily injury, in the event
of sudden braking or a colli-
sion.

vehicle last longer, too
Before starting the engine
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, seat cushion angle, head re-
straint height and steering wheel
angle.
3. Adjust inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and ac-
cessories.
3. Manual transmission: Press the
clutch pedal to the floor and shift
the transmission into neutral. Hold
the clutch pedal to the floor until
the engine is started. A starter
safety device will prevent the start-
er from operating if the clutch ped-
al is not fully depressed.
Automatic transmission: Put the
selector lever in ºPº. If you need to
restart the engine while the vehicle
is moving, put the selector lever in
ºNº. A starter safety device will pre-
vent the starter from operating if the
selector lever is in any drive position.
4. Automatic transmission only: De-
press the brake pedal and hold it
to the floor until driving off.
How to start the engineÐ
(a) Before cranking

4RUNNER (1998)
(b) Starting the engine
Before starting the engine, be sure to
follow the instructions in º(a) Before
crankingº.
Normal starting procedure
The multiport fuel injection system/se-
quential multiport fuel injection system
in your engine automatically controls
the proper air- fuel mixture for starting.
You can start a cold or hot engine as
follows:
1. With your foot off the accelerator
pedal, crank the engine by turning the
key to ºSTARTº. Release it when the
engine starts.
2. After the engine runs for about 10
seconds, you are ready to drive.
If the weather is below freezing, let
the engine warm up for a few minutes
before driving.
If the engine stalls...
Simply restart it, using the correct
procedure given in normal starting.
If the engine will not startÐ
See ºIf your vehicle will not startº in
Part 4.
NOTICE
Do not crank for more than 30 seconds at a time. This mayoverheat the starter and wiringsystems.
Do not race a cold engine.
If the engine becomes difficult
to start or stalls frequently,have the engine checked im-mediately.
Always slow down in gusty cross-
winds. This will allow you much
better control.
Drive slowly onto curbs and, if
possible, at a right angle. Avoid
driving onto high, sharp- edged ob-
jects and other road hazards. Fail-
ure to do so can lead to severe
tire damage resulting in tire bursts.
When parking on a hill, turn the
front wheels until they touch the
curb so that the vehicle will not
roll. Apply the parking brake, and
place the transmission in ºPº (auto-
matic) or in first or reverse (manu-
al). If necessary, block the wheels.
Washing your vehicle or driving
through deep water may get the
brakes wet. To see whether they
are wet, check that there is no
traffic near you, and then press the
pedal lightly. If you do not feel a
normal braking force, the brakes
are probably wet. To dry them,
drive the vehicle cautiously while
lightly pressing the brake pedal
with the parking brake pulled. If
they still do not work safely, pull to
the side of the road and call a
Toyota dealer for assistance.
Tips for driving in various
conditions

4RUNNER (1998)
Four- wheel drive modelsÐToyota
recommends not using four- wheel
drive on dry hard- surfaced roads,
because four- wheel driving will
cause unnecessary noise and wear,
and poor fuel economy.
Four- wheel drive modelsÐIn cold
temperatures, noise may occur
when driving in two- wheel drive
before the transfer is warmed up.
Therefore, first drive in four- wheel
drive until the transfer is warmed up.CAUTION
Before driving off, make sure
that the parking brake is fully
released and the parking brake
reminder light is off.
Do not leave your vehicle unat-
tended while the engine is run-
ning.
Do not rest your foot on the
brake pedal while driving. It can
cause dangerous overheating,
needless wear, and poor fuel
economy.
To drive down a long or steep
hill, reduce your speed and
downshift. Remember, if you
ride the brakes excessively,
they may overheat and not work
properly.Be careful when accelerating,
upshifting, downshifting or
braking on a slippery surface.
Sudden acceleration or engine
braking, could cause the vehicle
to spin or skid.
Do not drive in excess of the
speed limit. Even if the legal
speed limit permits it, do not
drive over 140 km/h (85 mph)
unless your vehicle has
high- speed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss
of control and possible injury.
Be sure to consult a tire dealer
to determine whether the tires
on your vehicle are high- speed
capability tires or not before
driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they
are wet, your vehicle will re-
quire a longer stopping dis-
tance, and it may pull to one
side when the brakes are ap-
plied. Also, the parking brake
will not hold the vehicle secure-
ly.

4RUNNER (1998)
Use a washer fluid containing an
antifreeze solution.
This product is available at your Toyo-
ta dealer and most auto parts stores.
Follow the manufacturer 's directions
for how much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because itmay damage your vehicle's paint.
Do not use your parking brake
when there is a possibility it could
freeze.
When parking, put the transmission
into ºPº (automatic) or into first or
reverse (manual) and block the rear
wheels. Do not use the parking brake,
or snow or water accumulated in and
around the parking brake mechanism
may freeze, making it hard to release.
Keep ice and snow from accumulat-
ing under the fenders.
Ice and snow built up under your
fenders can make steering difficult.
During bad winter driving, stop and
check under the fenders occasionally. Depending on where you are driv-
ing, we recommend you carry some
emergency equipment.
Some of the things you might put in
the vehicle are tire chains, window
scraper, bag of sand or salt, flares,
small shovel, jumper cables, etc.
Trailer towing
Your vehicle is designed primarily as
a passenger- and- load- carrying ve-
hicle. Towing a trailer will have an
adverse effect on handling, perfor-
mance, braking, durability and driving
economy (fuel consumption, etc.).
Your safety and satisfaction depend
on the proper use of correct equip-
ment and cautious driving habits. For
your safety and the safety of others,
you must not overload your vehicle or
trailer. Ask your local Toyota dealer
for further details before towing.
WEIGHT LIMITS
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, gross
axle weight and trailer tongue load
are all within the limits.
The total trailer weight and tongue
load can be measured with platform
scales found at a highway weighing
station, building supply company,
trucking company, junk yard, etc.

4RUNNER (1998)
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.

Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps pre-
vent corrosion.
Keep your vehicle tuned- up and
in top shape. A dirty air cleaner,
improper valve clearance, dirty
plugs, dirty oil and grease, brakes
not adjusted, etc. all lower engine
performance and contribute 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 main-
tenance information, please refer to
the separate ºOwner 's Manual Sup-
plement/Maintenance Scheduleº).
CAUTION
Never turn off the engine to coast
down hills. Your power steering
and brake booster will not func-
tion without the engine running.
Also, the emission control system
operates properly only when the
engine is running.
