When driving off- road or in rugged
terrain, do not drive at excessive
speeds, jump the vehicle, or strike
objects, etc. This may cause loss of
control or vehicle roll- over. You are
also risking expensive damage to
your vehicle's suspension and chas-
sis.
Break- in period
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).
Four- wheel drive models with free-
wheeling hubs onlyÐ
For the first 500 km (300 miles):
We recommend that you use high range,
two- wheel drive, with both free- wheeling
hubs engaged. For information on the
four- wheel drive system and the front
hubs, see ºFour- wheel drive systemº in
Chapter 1- 6. Fuel
FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mix- ups, your
Toyota has a new smaller fuel tank open-
ing. The special nozzle on pumps with
unleaded fuel will fit it, but the larger
standard nozzle on pumps with leaded gas
will not.
At a minimum, the gasoline you use
should meet specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5- M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three-way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,this can increase maintenance costs.

To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open. Have the cause immediately
located and corrected.
Toyota does not recommend occu-
pying the rear cargo area when it
is fitted with a slide- in camper,
camper shell or other type cover
while the engine is running. This
caution applies to both driving and
stopped or parked situations with
the engine running. Particular care
should be taken to prevent exhaust
gases from entering camper bodies,
trailers or other enclosures on or
around your vehicle. If exhaust
fumes are detected, open all win-
dows and thoroughly ventilate the
area.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 main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal 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 pis-
ton moves downwards in the cylinder.
High negative 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 cylinder wall is burned
by the high temperature 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 combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high- speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, 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 nor-
mal 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.

1. Rinse off loose dirt with a hose. Re-
move any mud or road salt from the
underside of the vehicle or in the
wheel wells.
2. Wash with a mild car- wash soap, mixed according to the manufacturer 's
instructions. Use a soft cotton mitt and
keep it wet by dipping it frequently into
the wash water. Do not rub hardÐlet
the soap and water remove the dirt.
Aluminum wheels: Use only a mild soap
or neutral detergent.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
NOTICE
Do not use gasoline or strong sol- vents, which may be toxic or causedamage.
3. Rinse thoroughlyÐdried soap can cause streaking. In hot weather you
may need to rinse each section right
after you wash it.
4. To prevent water spots, dry the vehicle using a clean soft cotton towel. Do not
rub or press hardÐyou might scratch
the paint. Waxing your Toyota
Polishing and waxing is recommended
to maintain the original beauty of your
Toyota's finish.
Once a month or if the vehicle does not
repel water well, apply wax.
1. Always wash and dry the vehicle be- fore you begin waxing, even if you are
using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become extremely weath-
ered, use a car- cleaning polish, fol-
lowed by a separate wax. Carefully fol-
low the manufacturer 's instructions and
precautions. Be sure to polish and wax
the chrome trim as well as the paint.
3. Wax the vehicle again when water does not bead but remains on the sur-
face in large patches. Cleaning the interior
CAUTION
Do not wash the vehicle floor with
water, or allow water to get onto the
floor when cleaning the vehicle interi-
or or exterior. Water may get into
audio components or other electrical
components above or under the floor
carpet (or mat) and cause a malfunc-
tion; and it may cause body corro-
sion.
Vinyl interior
The vinyl upholstery may be easily
cleaned with a mild soap or detergent
and water.
First vacuum over the upholstery to re-
move loose dirt. Then, using a sponge or
soft cloth, apply the soap solution to the
vinyl. After allowing it to soak in for a few
minutes to loosen the dirt, remove the dirt
and wipe off the soap with a clean damp
cloth. If all the dirt do not come off, re-
peat the procedure. Commercial foaming-
type vinyl cleaners are also available
which work well. Follow the manufacturer 's
instructions.

NOTICE
Do not use solvent, thinner, gasoline or window cleaner on the interior.
Carpets
Use a good foam- type shampoo to
clean the carpets.
Begin by vacuuming thoroughly to remove
as much dirt as possible. Several types of
foam cleaners are available; some are in
aerosol cans and others are powders or
liquids which you mix with water to pro-
duce a foam. To shampoo the carpets,
use a sponge or brush to apply the foam.
Rub in overlapping circles.
Do not apply waterÐthe best results are
obtained by keeping the carpet as dry as
possible. Read the shampoo instructions
and follow them closely.
Seat belts
The seat belts may be cleaned with
mild soap and water or with lukewarm
water.
Use a cloth or sponge. As you are clean-
ing, check the belts for excessive wear,
fraying, or cuts.
NOTICE
Do not use dye or bleach on thebeltsÐit may weaken them.
Do not use the belts until they be-come dry.
Windows
The windows may be cleaned with any
household window cleaner.
NOTICE
When cleaning the inside of the win-
dows, be careful not to scratch ordamage the heater wires on the rear window.
Air conditioning control panel, car au-
dio, instrument panel, console panel,
and switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly wipe off dirt.
NOTICE
Do not use organic substances (sol-
vents, kerosene, alcohol, gasoline,etc.) or alkaline or acidic solutions.These chemicals can cause discol-
oring, staining or peeling of thesurface.
If you use cleaners or polishing
agents, make sure their ingredientsdo not include the substances men-tioned above.
If you use a liquid car freshener, do
not spill the liquid onto the ve-
hicle's interior surfaces. It may con-tain the ingredients mentioned above. Immediately clean any spill
using the method mentioned above.
Leather Interior
The leather upholstery may be cleaned
with neutral detergent for wool.
Remove dirt using a soft cloth dampened
with 5% solution of neutral detergent for
wool. Then thoroughly wipe off all traces
of detergent with a clean damp cloth.
