When driving offroad or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover
causing death or serious injury. You
are also risking expensive damage
to your vehicle’s suspension and
chassis.
Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your ve-
hicle (or any similar offroad ve-
hicle) can tip over sideways much
more easily than forward or back-
ward.
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:
Avoid full throttle acceleration when
starting and driving.
Avoid racing the engine.
Try to avoid hard stops during the first
300 km (200 miles).
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 mix
−ups, your
Toyota has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard 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.

OCTANE RATING
Select Octane Rating 87 (Research
Octane Number 91) or higher.
Use of unleaded gasoline with an Octane
Rating lower than 87 may result in engine
knocking. Persistent knocking can 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 speed on level roads, consult your
Toyota dealer.
However, occasionally, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is normal
and there is no need for concern. GASOLINE CONTAINING DETERGENT
ADDITIVES
Toyota recommends the use of gasoline
that contains detergent additives to
avoid buildup of engine deposits.
However, all gasoline sold in the U.S.
contains detergent additives to keep clean
and/or clean intake systems.
QUALITY GASOLINE
Automotive manufacturers in the U.S.,
Europe and Japan have developed a
specification for quality fuel named
WorldWide Fuel Charter (WWFC) that
is expected to be applied world wide.
The WWFC consists of four categories
that depend on required emission lev-
els. In the U.S., category 3 or 4 has
been adopted. The WWFC improves air
quality by providing for better emis-
sions in vehicle fleets, and customer
satisfaction through better vehicle per-
formance.CLEANER BURNING GASOLINE
Cleaner burning gasoline, including re-
formulated gasoline that contains oxy-
genates such as ethanol or MTBE is
available in many areas.
Toyota recommends the use of cleaner
burning gasoline and appropriately blended
reformulated gasoline. These types of gas-
oline provide excellent vehicle perfor-
mance, reduce vehicle emissions, and im-
prove air quality.
OXYGENATES IN GASOLINE
Toyota allows the use of oxygenate
blended gasoline where the oxygenate
content is up to 10% ethanol or 15%
MTBE. If you use gasohol in your
Toyota, be sure that it has an octane
rating no lower than 87.
Toyota does not recommend the use of
gasoline containing methanol.

Do not leave the engine running in
an area with snow buildup, or
where it is snowing. If snowbanks
build up around the vehicle while
the engine is running, exhaust
gases may collect and enter the ve-
hicle. This may lead to death or a
serious health hazard.
When taking a nap in the vehicle,
always turn the engine off. Other-
wise, you may accidentally move
the shift lever or depress the accel-
erator pedal, which could cause an
accident or fire due to engine over-
heating. Additionally, if the vehicle
is parked in a poorly ventilated
area, exhaust gases may collect and
enter the vehicle, leading to death
or a serious health hazard.
Toyota does not recommend occu-
pying the rear cargo area when it
is fitted with a slidein 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.

Exterior lights: Do not apply wax on the
surfaces of the lights. Wax may cause
damage to the lenses. If you accidentally
put wax on the light surfaces, wipe or
wash it off.
3. Wax the vehicle again when water does not bead but remains on the sur-
face in large patches.CAUTION
Be careful not to splash water or
spill liquid on the floor. This may
prevent the side airbags and curtain
shield airbags from activating cor-
rectly, resulting in serious injury.
Do not wash the vehicle floor with
water, or allow water to get onto
the floor when cleaning the vehicle
interior or exterior. Water may get
into audio components or other
electrical components above or un-
der the floor carpet (or mat) and
cause a malfunction; and it may
cause body corrosion.
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 foamtype 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.

The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the engine switch and
light switch are off. Use bulbs with the
wattage ratings given in the table.
The side turn signal lights consist of a
number of LEDs. If any of the LEDs burn
out, take your vehicle to your Toyota deal-
er to have the light replaced.
CAUTION
To prevent burning yourself, do not
replace the light bulbs while they
are hot.
Halogen bulbs have pressurized gas
inside and require special handling.
They can burst or shatter if
scratched or dropped. Hold a bulb
only by its plastic or metal case.
Do not touch the glass part of a
bulb with bare hands.
NOTICE
Only use a bulb of the listed type.
The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens becomes wet in the rain or
in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lens, just like the
windshield fogs up in the rain. However, if
there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your
Toyota dealer. Light bulbsBulb
