Type 4: AM·FM ETR radio/cassette player/
compact disc auto changer controller This section describes some of the basic
features on Toyota audio systems. Some
information may not pertain to your sys-
tem.
Your audio system works when the ignition
key is in the ”ACC” or ”ON” position.
TURNING THE SYSTEM ON AND OFF
Push ”PWR/VOL” or ”VOL/PWR” to turn
the audio system on and off.
Push ”AM”, ”FM”, ”AM·FM”, ”TAPE” or
”CD” to turn on that function without push-
ing ”PWR/VOL” or ”/VOL/PWR”.
You can turn on the cassette player by
inserting a cassette tape.
You can turn off the cassette player by
ejecting the cassette tape. If the audio
system was previously off, then the entire
audio system will be turned off when you
eject the cassette tape. If the radio was
previously on, it will come on again.
SWITCHING BETWEEN FUNCTIONS
Push ”AM”, ”FM”, ”AM·FM”, ”TAPE” or
”CD” if the system is already on but you
want to switch from one function to anoth-
er.
TONE AND BALANCE
For details about your system’s tone and
balance controls, see the description of
your own system.
Tone
How good an audio program sounds to
you is largely determined by the mix of
the treble, midrange, and bass levels. In
fact, different kinds of music and vocal
programs usually sound better with differ-
ent mixes of treble, midrange, and bass.
Balance
A good balance of the left and right stereo
channels and of the front and rear sound
levels is also important.
Keep in mind that if you are listening to
a stereo recording or broadcast, changing
the right/left balance will increase the vol-
ume of one group of sounds while de-
creasing the volume of another.

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.

Types of tires
Determine what kind of tires your ve-
hicle is originally equipped with.
1. Summer tires
Summer tires are high-speed capability
tires best suited to highway driving under
dry conditions.
Since summer tires do not have the same
traction performance as snow tires, sum-
mer tires are inadequate for driving on
snow-covered or icy roads. For driving on
snow-covered or icy roads, we recommend
using snow tires. If installing snow tires,
be sure to replace all four tires. 2. All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions, as
well as for use all year round.
All season tires, however, do not have
adequate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accel-
eration and handling performance
compared with summer tires in highway
driving.
CAUTION
Do not mix summer and all season
tires on your vehicle as this can
cause dangerous handling charac-
teristics, resulting in loss of con-
trol.
Do not use tire other than the
manufacture’s designated tires, and
never mix tires or wheels of the
sizes different from the originals.

Checking the engine oil level
With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick. 1. To get a true reading, the vehicle should be on a level spot. After turning
off the engine, wait a few minutes for
the oil to drain back into the bottom of
the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick–push it in as far as it will go, or the reading will not be
correct.
4. Pull the dipstick out and look at the oil level on the end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler cap and add engine
oil in small quantities at a time, checking
the dipstick.
The approximate quantity of oil needed to
fill between the low level and the full level
on the dipstick is indicated below for ref-
erence.
When the level reaches within the correct
range, install the filler cap hand-tight.

Checking and replacing tires
CHECKING YOUR TIRES
Check the tire tread for the tread wear
indicators. If the indicators show, re-
place the tires.
The tires on your Toyota have built-in
tread wear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If
you can see the indicators in two or more
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16 in.).
Check the tires regularly for damage
such as cuts, splits and cracks. If any
damage is found, consult with a techni-
cian and have the tire repaired or re-
placed.
Even if the damage does not appear seri-
ous, a qualified technician should examine
the damage. Objects which have pene-
trated the tire may have caused internal
damage.
Any tires which are over six years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This also applies to the spare tire and
tires stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use only the
same size and construction as original-
ly installed and with the same or great-
er load capacity.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
and clearance between the body and tires
or snow chains.
CAUTION

Do not mix radial, bias belted, or
bias-ply tires on your vehicle. It can
cause dangerous handling charac-
teristics, resulting in loss of con-
trol.
Do not use tires or wheels other
than the manufacturer ’s recom-
mended size.
Toyota recommends all four tires, or at
least both of the front or rear tires be
replaced at a time as a set.
See ”If you have a flat tire” in Part 4 for
tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
handling and tire life. Wheels can get out
of balance with regular use and should
therefore be balanced occasionally.
When replacing a tubeless tire, the air
valve should also be replaced with a
new one.

CAUTION
Do not drive with the snow tires
incorrectly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.
TIRE CHAIN SELECTION
Use the tire chains of correct size.
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check them
before installing chains.
CHAIN INSTALLATION
Install the chains on the rear tires as
tightly as possible. Do not use tire
chains on the front tires. Retighten
chains after driving 0.5–1.0 km (1/4–1/2
mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.
CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or locked-wheel
braking as use of chains may ad-
versely affect vehicle handling.
Replacing wheels
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or they may
cause loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.
Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
