When driving off-road or in
rugged terrain, do not drive at ex- cessive speeds, jump the vehicle,
or strike objects, etc. This may cause loss of control or vehicle
rollover. You are also risking ex-
pensive damage to your vehicle's suspension and chassis. Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break-in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of your vehicle:
Do not drive over 88 km/h (55 mph).
Run the engine at moderate speed be- tween 2000 and 4000 rpm.
Avoid full-throttle starts.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive slowly with the manual
transmission in a high gear.
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles). Selecting the proper fuel is essential
for satisfactory engine performance.
Engine
damage caused by use of improp-
er fuels is not covered under T oyota's new
vehicle warranty. FUEL TYPEUse only unleaded gasoline.
To help prevent gas station mixups, ve-
hicles designed for use with unleaded gaso-
line have a new smaller fuel tank opening.
The special nozzle on pumps with unleaded
fuel will fit it, but the larger standard nozzle
on pumps with leaded gas will not.
Do not use leaded gasoline. Use of
leaded gasoline will cause the
three-way catalytic converter tolose its effectiveness and the emission control system tofunction improperly. Also, this can increase maintenance costs.
NOTICE
Break-in period Fuel

111
A large amount of unburned gasesflowing into the three-way
catalytic converter may cause it tooverheat and create a fire hazard. To prevent this and other damage,observe the following precautions:
Use only unleaded gasoline.
Do not drive with an extremelylow fuel level; running out of fuelcould cause the engine to mis-
fire, creating an excessive load
on the three-way catalytic con-verter.
Do not allow the engine to run at
idle speed for more than 20 min-utes.
Avoid racing the engine.
Do not push-start or pull-startyour vehicle.
Do not turn off the ignition while
the vehicle is moving.
NOTICEKeep your engine in good run-ning order. Malfunctions in the
engine electrical system, elec-tronic ignition system/distributorignition system or fuel systems
could cause an extremely high
three-way catalytic convertertemperature.
If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check-up as soon
as possible. Remember, your
Toyota dealer knows your vehicleand its three-way catalytic
converter system best.
To ensure that the three-way cat-alytic converter and the entire
emission control system operate
properly, your vehicle must re-ceive the periodic inspections re-
quired by the Toyota Maintenance
Schedule. For scheduled mainte- nance information, refer to the
separate Owner's Manual Sup- plement/Maintenance Scheduleº.
CAUTION!
Avoid inhaling the engine exhaust.
It contains carbon monoxide,
which is a colorless and odorless
gas. It can cause unconsciousness
or even death.
Make sure the exhaust system has
no holes or loose connections. The
system should be checked from
time to time. If you hit something,
or notice a change in the sound of
the exhaust, have the system
checked immediately.
Do not run the engine in a garage or
enclosed area except for the time
needed to drive the vehicle in or
out. The exhaust gases cannot es-
cape, making this a particularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined areaand adjust the heating or cooling
system to force outside air into the vehicle.
Engine exhaust cautions

11 3
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making itappear that oil is excessively consumed
after driving as high speeds.
IMPORTANCE OF ENGINE OIL LEVEL 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 essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level bechecked every time you refuel the vehicle.
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficient oil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.
Your engine is fitted with twin ground elec- trode spark plugs.
Use only twin ground electrode
spark plugs for your engine
performance.
NOTICE
TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fail, the other w ill still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
Also, the brake system warning light may come on.
CAUTION!
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stops - but no more!

If driving through water, such as
when crossing shallow streams,
first check the depth of the waterand the bottom of the river bed forfirmness. Drive slowly and avoid
deep water.
Take all necessary safety measuresto ensure that damage to the en-
gine or o ther components does not
occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease fromwheel bearings, causing rustingand premature failure, and mayalso enter the differential,
transmission and transfer case, reducing the gear oil's lubricatingqualities.
Sand and mud that has accumu-lated in brake drums and around
brake discs may affect braking effi-
ciency and may damage brake sys-tem components.
NOTICEAlways perform a maintenance in-spection after each day of off-
road driving that has taken you through rough terrain, sand, mud,
or water. For scheduled mainte-
nance information, refer to theseparate Owner's Manual Sup-plement/Maintenance Scheduleº.Make sure you have ethylene-glycol
antifreeze in the radiator.
Do not use alcohol type antifreeze.
NOTICE
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 in-
spect the battery. Your Toyota dealer and
most service stations will be pleased tocheck the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Chapter 7-2 for recommended vis-
cosity. 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 dealer- he 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 in-serting it.
Winter driving tips

TRAILER LIGHTS
Trailer lights must comply with federal,
state/provincial and local regulations. See your local recreational vehicle
dealer or rental agency for the correcttype 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 ve-
hicle with any new power train compo-
nent (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 re-
quire more frequent maintenance due
to the additional load. For this informa-
tion, please refer to the scheduled
maintenance information in the Own-
er 's Manual Supplement/MaintenanceScheduleº.
Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving. PRE-T OWING 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 suspen-
sion 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.
TRAILER TOWING TIPS
When towing a trailer, your vehicle will
handle differently than when not tow-ing. The three main causes of vehicle
trailer accidents are driver error, ex-
cessive speed and improper trailer
loading. Keep these in mind when tow-
ing: Before starting out, check operation of
the lights and all vehicle-trailer con-
nections. After driving a short dis-
tance, stop and recheck the lights and
connections. Before actually towing a
trailer, practice turning, stopping and
backing with a trailer in an area away
from traffic until you learn the feel.
Backing w ith a trailer is difficult and re-
quires practice. Grip the bottom of the steering wheel and move your hand to
the left to move the trailer to the left. Move your hand to the right to move
the trailer to the right. (This procedureis generally opposite to that when
backing without a trailer). Also, just
turn the steering wheel a little at a time,
avoiding sharp or prolonged turning. Have someone guide you when back-
ing to reduce the risk of an accident.
Because stopping distance may be in-
creased, vehicle-to-vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as you may skid, resulting in jackknifing and loss of control This is especially
true on wet or slippery surfaces.
Avoid jerky starts or sudden accelera-tion. If your vehicle has manual trans-
mission, prevent excessive clutch slip-
page by keeping engine rpm low and
not racing the engine. Always start out
in first gear.

132
Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps preventcorrosion.
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 con-
tribute to poor fuel economy. For lon-
ger 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 ve-
hicle receives more frequent mainte-
nance (For scheduled maintenance in-
formation, please refer to the separate
Owner 's Manual Supplement/Main-
tenance Scheduleº).
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, theemission control system operates
properly only when the engine isrunning.!

VEHICLE
MAINTENANCE ANDCARE
Maintenance requirements
General maintenance
Does your vehicle need repairing?
For scheduled maintenance infor-
mation, please refer to the sep-
arate Owner's Manual Sup-
plement/Maintenance Scheduleº.
Your Toyota vehicle has been designed to
for fewer maintenance requirements with longer service intervals to save both your
time and money. However, each regular
maintenance, as well as day-to-day
care, is more important than ever before
to ensure smooth, trouble-free, safe, and
economical drivings.
It is the owner's responsibility to make sure
the specified maintenance, including
general maintenance service, is per-
formed. Note that both the new vehicle
and emission control system warranties
specify that proper maintenance and care
must be performed. See Owner's Guide,
Owner 's Manual Supplement or W arranty
Booklet for complete warranty informa- tion.
General maintenance General maintenance items are those
day-to-day care practices that are impor-
tant to your vehicle for proper operation.
It is the owner's responsibility to insure that the general maintenance items are
performed regularly.
These checks or inspections can be done
either by yourself or a qualified technician,
or if you prefer, your Toyota dealer will be
pleased to do them at a nominal cost. Scheduled maintenance
The scheduled maintenance items listed
in the Owner's Manual Supplement/
Maintenance Scheduleº are those re-
quired to be serviced at regular intervals.
For details of your maintenance Sched-
ule, read the separate Owner's Manual
Supplement/Maintenance Scheduleº.
It is recommended that any replace-
ment parts used for maintenance or
for the repair of the emission control
system be Toyota supplied.
The owner may elect to use
non- Toyo-
ta supplied parts for replacement pur-
poses without invalidating the emis-
sion control system warranty.
However, use of replacement parts
which are not of equivalent quality
may impair the effectiveness of the
emission control systems.
You may also elect to have mainte-
nance, replacement, or repair of the
emission control devices and system
performed by any automotive repair
establishment or individual without
invalidating this warranty. See Own-
er's Guide, Owner's Manual Supple-
ment or Warranty Booklet for complete
warranty information.

158Where to go for service?
Toyota technicians are well-trained spe- cialists
and are kept up to date with the lat-
est service information through technical
bulletins, service tips, and in-dealership
training programs. 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 require-
ments on your vehicleÐreliably and eco-
nomically.
Your copy of the repair order is proof that
all required maintenance has been per-
formed 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
service 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 mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form 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 maintenance can affect your
warranty coverage. See Owner's Guide,
Owner 's
Manual Supplement or W arranty
Booklet for the details. Listed
below are the general maintenance
items that should be performed as fre-quently as specified. In addition to check-
ing the items listed, if you notice any un-
usual noise, smell or vibration, you should
investigate the cause or take your vehicle
to your T oyota 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.
Make these checks only where
adequate ventilation can be ob-
tained if you run the engine. CAUTION
!
OUTSIDE THE VEHICLE
Items listed below should be per-
formed from time to time, unless
otherwise specified.
