CAUTION!
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 rollover. You are
also risking expensive 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) FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups, your
Toyota has 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 emis- sion control system to function im-properly. Also, this can increase maintenance costs.
NOTICE
OCTANE NUMBER
Select Research Octane Number 91 (Oc-
tane Rating 87) or higer.
Use of unleaded fuel with an octane num- ber or rating lower than stated above will
cause persistant heavy knocking. If se-
vere, this will lead to engine damage.

If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady sp
eed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or d riving up hills. This is no cause
for concern.
GASOLINES CONTAINING DETER-
GENT ADDITIVES
Toyota recommends use of gasolines
that contain detergent additives to
avoid build-up of engine deposits.
For further details, ask your Toyota dealer
or a local gasoline retailer.
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Methyl
Tertiary-Butyl Ether) are available in
the market. If you use a gasoline mixed
with MTBE, make certain that it does
not contain more than 15% of MTBE.
If the use of gasolines containing MTBE causes poor driveability and/or poor fuel
economy, you should discontinue the use
of fuels containing MTBE. GASOLINES CONTAINING ALCOHOL
If the use of gasohol in your T
oyota, be
sure that it is u nleaded, has an octane
rating no lower than 87 and does not
contain more than 10% ethonol.
Gasohol is a mixture of gasoline and etha-
nol.
Toyota does not recommend the use of
gasolines containing m ethonol. If you use
gasoline containing methonol, use only
gasoline meeting the requirements above
and also containing less than 5% metha-
nol with cosolvents and corrosion inhibi-
tors for methanol.

Do not use gasohol other thanstated above. It will cause fuel
system damage or vehicle perfor- mance problems.
If driveability problems are en-
countered (poor hot starting, va-porizing, engine knock, etc.), dis-continue the use.
Take care not to spill gasohol dur-
ing refueling. Gasohol may causepaint damage.
