Do not place anything on the
filler panel or l uggage cover.
Such items may be thrown
about and possibly injure
people in the vehicle during
sudden braking or an accident.
(secure all items in a safe
place.)
Do not drive with objects left
on top of the instrument panel.
They may interfere with the
driver's field of view. Or they
may move during sharp vehicle
acceleration or turning, and im-
pair the driver's control of the
vehicle. In an accident they may
injure the vehicle occupants.
NOTICE
Do not load the vehicle beyond
the vehicle capacity weight speci-fied in Part 8.

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.

Total trailer weight
Tongue load
Tongue load
Total trailer weight
100 9 to 11 %
The trailer cargo load should be
distributed so that the tongue
load is 9 to 11% of the total
trailer weight, not exceeding the
maximum of the following. Nev-
er load the trailer with more
weight in the back than in the
front. About 60% of the trailer
load should be in the front half
of the trailer and the remaining
40% in the rear.
3RZ- FE engine158 kg (350 lb.)
5VZ- FE engine 226 kg (500 lb.)HITCHES
Use only a weight carrying hitch
designed for the total trailer weight.
Toyota does not recommend using
a weight distribution (load equaliz-
ing) hitch.
The hitch must be bolted securely
to the vehicle frame and installed
according to the hitch manufactur-
er 's instructions.
The hitch ball and king pin should
have a light coat of grease.
Toyota recommends removing the
hitch when not towing to preventin-
jury and/or damage due to the
hitch in event of a rear end colli-
sion. After removal of the hitch,
seal the installation area to prevent
entry of exhaust fumes and mud.
NOTICE
Do not use an axle- mounting
hitch as it may cause damage tothe axle housing, wheel bearings,wheels and or tires.
BRAKES AND SAFETY CHAINS
Toyota recommends trailers with
brakes that conform to any appli-
cable federal and state/provincial
regulations.

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.

Turn the jack joint by hand.
To remove: Turn the joint in direction
1 until the jack is free.
To store: Turn the joint in direction 2
until the jack is firmly secured to pre-
vent it flying forward during a collision
or sudden braking.

4RUNNER (1998)
To remove the spare tire:
1. Insert the end of the jack handle into the lowering screw and turn it
counterclockwise.
2. After the tire is lowered completely to the ground, remove the holding
bracket.
When storing the spare tire, put it in
place with the outer side of the wheel
facing up. Then secure the tire, taking
care that the tire goes straight up
without catching on any other part, to
prevent it from flying forward during a
collision or s udden braking. ÐBlocking the wheel

4RUNNER (1998)
9. Lower the vehicle completely and
tighten the wheel nuts.
Turn the jack handle extension coun-
terclockwise with handle to lower the
vehicle, making sure the handle re-
mains firmly fitted onto the jack han-
dle extension.
Use only the wheel nut wrench and
turn it clockwise to tighten the nuts.
Do not use other tools or any addi-
tional leverage other than your hands,
such as a hammer, pipe or your foot.
Make sure the wrench is securely en-
gaged over the nut.
Tighten each nut a little at a time in
the order shown. Repeat the process
until all the nuts are tight.
CAUTION
When lowering the vehicle, make
sure all portions of your body
and all other persons around will
not be injured as the vehicle is
lowered to the ground.
ÐReinstalling wheel orna-
ment

4RUNNER (1998)
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.
