oughly extinguish it in the ashtray to pre-
vent other cigarette butts from catching
fire. After using the ashtray, push it back
in completely.
To remove the ashtray, press down on the
lock spring plate and pull out.
CAUTION
To reduce the chance of injury in
case of an accident or sudden stop
while driving, always push the ash-
tray back in completely after using.

Types of tires
This vehicle is one of the class of ve-
hicles which have higher ground clear-
ance and narrower tread in relation to
the height of their center of gravity to
make them capable of performing in a
wide variety of off- road applications.
Specific design characteristics give it a
higher center of gravity than ordinary
cars. An advantage of the higher
ground clearance is a better view of the
road allowing you to anticipate prob-
lems. It is not designed for cornering
at the same speeds as conventional
two- wheel drive vehicles any more than
low- slung sports cars are designed to
perform satisfactorily under off- road
conditions.

CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle:

Avoid sharp turns or abrupt maneu-
vers, if at all possible. As with oth-
er vehicles of this type, failure to
operate this vehicle correctly may
result in loss of control or vehicle
rollover.

Avoid loading any items on the roof
that will make the center of gravity
even higher.

Always slow down in gusty cross-
winds. Because of its high center of
gravity, your vehicle is more sensi-
tive to side winds than an ordinary
passenger car. Slowing down will
allow you to have much better con-
trol.

Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your ve-
hicle (or any similar off- road ve-
hicle) can tip over sideways much
more easily than forward or back-
ward.

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 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).

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 ofleaded 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 Oc-
tane Number 91) or higher.
Use of unleaded gasoline with an octane
rating or research octane number lower
than stated above will cause persistent
heavy knocking. If it is severe, 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 speed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no need
of concern.
GASOLINES CONTAINING DETERGENT
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. IMPROVED GASOLINES
The American Automobile Manufacturers
Association (AAMA) has developed a
specification of improved gasolines. The
AAMA specification offers optimal fuel
information for better vehicle perfor-
mance and better protection of your en-
gine.
Toyota recommends the use of gasolines
that meet the AAMA specification, if avail-
able, for improved driveability and emis-
sion control system.
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.
GASOLINES CONTAINING MMT
Some gasolines contain an octane- en-
hancing additive called MMT (methylcy-
clopentadienyl manganese tricarbonyl).
ProCarManuals.com

TUNDRA (34413U)
168
Toyota does not recommend the use of
gasolines that contain MMT. If fuels con-
taining MMT are used, your emission con-
trol system may be adversely affected.
The Malfunction Indicator Lamp on the in-
strument cluster may come on. If this hap-
pens, contact your Toyota dealer for ser-
vice.
GASOLINES CONTAINING ALCOHOL
If you use gasohol in your Toyota, be
sure that it is unleaded, has an octane
rating no lower than 87 and does not
contain more than 10% ethanol.
Gasohol is a mixture of gasoline and etha-
nol.
Toyota does not recommend the use of
gasolines containing methanol. If you use
gasoline containing methanol, use only
gasoline meeting the requirements above
and also containing less than 5% metha-
nol with cosolvents and corrosion inhibi-
tors for methanol.
GASOLINES QUALITY
In a very few cases, you may experience
driveability problems caused by the partic-
ular gasoline that you are using. If you
continue to have unacceptable driveability,
try changing gasoline brands. If that does
not rectify your problem, then consult your
Toyota dealer.NOTICE

Do not use gasohol other thanstated above. It will cause fuel sys-tem damage or vehicle performanceproblems.

If driveab ility problems occur (poor
hot starting, vaporizing, engine knock, etc.), discontinue the use.

Take care not to spill gasohol dur-ing refueling. Gasohol may cause
paint damage.
FUEL TANK CAPACITY
100 L (26.4 gal., 22.0 Imp. gal.)
Operation in foreign countries
If you plan to drive your Toyota in
another country...
First, comply with the vehicle registration
laws.
Second, confirm the availability of the cor-
rect fuel (unleaded and minimum octane
number).

Three- way catalytic converters
Ty p e A
Ty p e B
Ty p e C
Ty p e D
The three- way catalytic converter is an
emission control device installed in the
exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION

Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.

Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.

NOTICE
A large amount of unburned gasesflowing into the three- way catalyticconverter may cause it to overheatand create a fire hazard. To prevent
this and other damage, observe thefollowing precautions:

Use only unleaded gasoline.

Do not drive with an extremely lowfuel level; running out of fuel could
cause the engine to misfire, creat-ing an excessive load on the three-way catalytic converter.

Do not allow the engine to run atidle speed for more than 20 minu-
tes.

Avoid racing the engine.

Do not push- start or pull- start yourvehicle.

Do not turn off the ignition while
the vehicle is moving.

Keep your engine in good runningorder. Malfunctions in the engineelectrical system, electronic ignitionsystem/distributor ignition system
or fuel systems could cause an ex-tremely high three- way catalyticconverter temperature.

If the engine becomes difficult tostart or stalls frequently, take yourvehicle in for a check- up as soon
as possible. Remember, your Toyotadealer knows your vehicle and itsthree- way catalytic converter sys-
tem best.

To ensure that the three- way cata-lytic converter and the entire emis-sion control system operate proper-ly, your vehicle must receive the
periodic inspections required by theToyota Maintenance Schedule. Forscheduled maintenance information,
refer to the separate ScheduledMaintenance Guideº or Owner'sManual Supplementº.
Engine exhaust cautions
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
escape, 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 area
and adjust the heating or cooling
system to force outside air into the
vehicle.

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.
