mph) Vehicles with cruise control'When the
cruise control is being used, even if
you downshift the transmission by
turning off the overdrive switch, en-
gine braking is not applied because
the cruise control is not cancelled.
For ways to decrease the vehicle
speed, see ºCruise controlº in this
chapter.
CAUTION
Be careful when downshifting on
a slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(c) Using º2º and ºLº positions
The º2º and ºLº positions are used for
strong engine braking as described
previously.
With the selector lever in º2º or ºLº,
you can start the vehicle in motion as
with the lever in ºDº.
With the selector lever in º2º, the ve-
hicle will start in the first gear and
automatically shift to the second gear.
With the selector lever in ºLº, the
transmission is engaged in the first
gear.
NOTICE
Be careful not to overrev the
engine. Watch the tachometer tokeep engine rpm from goinginto the red zone. The approxi-
mate maximum allowable speedfor each position is given belowfor your reference:
º2º
..........120 km/h (74 mph)
ºLº
.......... 65 km/h (40 mph)
Do not continue hill climbing or hard towing for a long time inthe º2º or ºLº position. This
may cause severe automatictransmission damage from over-heating. To prevent such dam-
age, ºDº position should beused in hill climbing or hardtowing.
(d) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector

ÐOperating tips
To cool off your Toyota after it has
been parked in the hot sun, drive
with the windows open for a few
minutes. This vents the hot air, al-
lowing the air conditioning to cool
the interior more quickly.
Make sure the air intake grilles in
front of the windshield are not
blocked (by leaves or snow, for
example).
On humid days, do not blow cold
air on the windshield. The wind-
shield could fog up because of the
difference in air temperature on the
inside and outside of the wind-
shield.
Keep the area under the front
seats clear to allow air to circulate
throughout the vehicle.
On cold days, move the fan speed
selector to ºHIº for a minute to
help clear the intake ducts of snow
or moisture. This can reduce the
amount of fogging on the windows. Heating
For best results, set controls to:
Fan speedÐ Any setting except
ºOFFº
TemperatureÐ To w a r d s WARM
(red zone)
Air intakeÐFRESH (outside air)
Air flowÐFLOOR
Air conditioningÐOFF
For quick heating, select recircu-
lated air for a few minutes. To
keep the windows from fogging, se-
lect fresh after the vehicle interior
has been warmed.
Press the ºA/Cº button on for dehu-
midified heating.
Choose floor/windshield air flow to
heat the vehicle interior while de-
frosting or defogging the wind-
shield. Air conditioning

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.

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)
The driver and all passengers
should fasten their seat belts
whenever the vehicle is moving.
NOTICE
If driving through water, such
as when crossing shallowstreams, first check the depth of the water and the bottom of
the river bed for firmness. Driveslowly and avoid deep water.
Take all necessary safety mea-
sures to ensure that water dam-age to the engine or other com- ponents does not occur.
Water entering the engine airintake will cause severe engine
damage.
Water can wash the grease fromwheel bearings, causing rustingand premature failure, and mayalso enter the differentials,
transmission and transfer case,reducing the gear oil's lubrica-ting qualities.
Sand and mud that has accum-
lated in brake drums andaround brake discs may affectbraking efficiency and may dam-
age brake system components.
Always perform a maintenanceinspection after each day of
off- road driving that has takenyou through rough terrain,sand, mud, or water. For sche-
duled maintenance information,refer to the separate ºOwner's Manual Supplement/Maintenance
Scheduleº.
Winter driving tips
Make sure you have ethylene- glycol
antifreeze in the radiator.
NOTICE
Do not use alcohol type anti-freeze.
Check the condition of the battery
and cables.
Cold temperatures reduce the capacity
of any battery, so it must be in top
shape to provide enough power for
winter starting. Chapter 7- 3 tells you
how to visually inspect the battery.
Your Toyota dealer and most service
stations will be pleased to check the
level of charge.
Make sure the engine oil viscosity
is suitable for the cold weather.
See Chapter 7- 2 for recommended
viscosity. Leaving a heavy summer oil
in your vehicle during winter months
may cause harder starting. If you are
not sure about which oil to use, call
your Toyota dealerÐhe will be pleased
to help.
Keep the door locks from freezing.
Squirt lock de- icer or glycerine into
the locks to keep them from freezing.
To open a frozen lock, try heating the
key before inserting it.

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.
