Windshield air flow button
When this button is pressed, air flows
mainly from the windshield vents and the
FRESH mode is automatically set. This
setting clears the front view more quickly.
If you want to return the setting to
RECIRCULATE mode, press the air intake
selector button once again.
Pressing the button once again returns the
air flow mode to the last one used.
Pressing the windshield air flow button
turns on the defrosterlinked air condition-
ing. This is to clean up the front view
more quickly. When the “A/C” button is not pressed in,
pressing another air flow button turns off
the air conditioning.
For details about air flow selector settings,
see “—Air flow selector settings” de-
scribed below.
Air intake selector
The air intake selector button is used to
switch the air intake FRESH
mode that
draws outside air into the system and
RECIRCULATED mode that recirculates
the air inside vehicle.
To turn the air source to RECIRCULATED
mode, press the button. The indicator will
come on. To turn the air source to FRESH
mode, press the button again. The indica-
tor will go off.
If the engine coolant temperature becomes
extremely high, RECIRCULATE mode will
automatically be selected. This is not a
malfunction. When the engine coolant tem-
perature is lowered, the previous mode
will resume.
To prevent fogging up of the windshield,
the air intake mode may change automati-
cally to FRESH depending on the condi-
tion of the air conditioning system.

Every time you push the “INFO” button,
the display toggles through this informa-
tion.
The displayed values in the multiinforma-
tion display indicate general driving condi-
tions. Accuracy varies with driving habits
and road conditions.
You can adjust the air conditioned temper-
ature while the multiinformation is operat-
ing. 5 seconds has been passed after ad-
justing the temperature or pushing “INFO”
button, the display will be back to the
multiinformation display. 1. Outside temperature
(“OUTSIDE TEMP”)
The outside temperature display indi-
cates the outside air temperature.
The displayed temperature ranges from
22 F (30 C) up to 122 F (50 C).
If there is some abnormality in the con-
nection of the outside air temperature sen-
sor, “ F” (“ C”) will appear on the
display. If “ F” (“ C”) appears on the
display, contact your Toyota dealer.
There may be a case that “ F” (“ C”)
appears momentarily when the ignition is
quickly turned to “ON”. It is normal if it
goes out soon.
2. Average vehicle speed (“AVG MPH” or “AVG km/h”)
Average vehicle speed is calculated and
displayed based on total driving dis-
tance and total driving time with the
engine running.
The displayed value is updated every 10
seconds.
To reset the calculation, push the “INFO”
button for more than 1 second.

3. Average fuel consumption
(“AVG MPG” or “AVG L/100 km”)
Average fuel consumption is calculated
and displayed based on total driving
distance and total fuel consumption
with the engine running.
The displayed value is updated every 10
seconds.
To reset the calculations, push the “INFO”
button for more than 1 second.
4. Instantaneous fuel consumption (“MPG” or “L/100 km”)
The instantaneous fuel consumption is
calculated and displayed based on dis-
tance and fuel consumption for 1 sec-
onds with the engine running.
The displayed value is updated every 2
seconds.
Note that an accurate figure may not be
shown in the following cases.
When the vehicle is stopped with the
engine running, the display will indicate
the extremely high fuel consumption.
When the vehicle is driving down a
long slope, applying the engine brake,
the display will indicate the extremely
low fuel consumption. The calculation is reset when the ignition
switch is turned off.
5. Driving time (“E/T”)
The elapsed time after the engine starts
is displayed.
When the engine is started, driving time
is counted from 0:00. Up to 11:59 (11
hours, 59 minutes) can be displayed.
When the driving time exceeds 11:59, the
counter returns to 0:00.
The calculation is reset when the ignition
switch is turned off.
The digital clock indicates the time.
The key must be in the “ACC” or “ON”
position.
To reset the hour: Push the “H” button.
To reset the minutes: Push the “M” button.
If the electrical power source has been
disconnected from the clock, the time dis-
play will automatically be set to 1:00 (one
o’clock).

Always slow down in gusty cross-
winds. Because of its profile and
higher center of gravity, your ve-
hicle is more sensitive to side
winds than an ordinary passenger
car. Slowing down will allow you to
have better control.
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
breakin. 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 mixups, 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 the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5M93
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
2AZFE engine: Select Octane Rating 87
(Research Octane Number 91) or higher.
1MZFE engine: Select Octane Rating
87 (Research Octane Number 91) or
higher. For improved vehicle perfor-
mance, the use of premium unleaded
gasoline with an Octane Rating 91 (Re-
search Octane Number of 96) or higher
is recommended.
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, 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 three categories
that depend on required emission lev-
els. In the U.S., category 3 has been
adopted. The WWFC improves air quali-
ty by providing for better emissions in
vehicle fleets, and customer satisfaction
through better vehicle performance.
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.
