Air intake selector
Press the button to select the air source.1. Recirculate— Recirculates the air inside
the vehicle.
2. Fresh— Draws outside air into the sys-
tem.
The air intake selector button is used to
switch the air intake FRESH mode that
draws outside air into the system and RE-
CIRCULATED 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. 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.
2way air intake control
To improve fuel economy, “Fresh” mode
control changes when the air intake se-
lector is set in “Fresh” mode on the
following conditions:
When the maximum heating is needed
with the air flow in “Floor” or “Floor/
Windshield”, fresh air flows in the up-
per compartment, while air is recircu-
lated in the lower compartment.
When cooling is needed, both fresh
and recirculate modes turns on.

Air conditioning onoff buttons
To turn on the air conditioning, push
the “A/C” button.
1. Turning off the air conditioning
Push the “A/C” button to turn off the air
conditioning. 2. Economical and environmentfriendly cooling
Usually use the air conditioning with the
“A/C” button on. If you push the button
again, the air conditioning turns off.

135
3. Powerful cooling and dehumidifying
If the air conditioning does not work well
with the “A/C” button on, push the “MAX”
button. To cancel the “MAX” mode, push
the “MAX” button again. To turn off the air
conditioning, push the “A/C” button.
With the “MAX” button on, the gasoline
engine is frequently used.
The air conditioning may not turn on with
the selector lever in “N” position because
the gasoline engine cannot start.
If the “A/C” button indicator flashes, there
is a problem in the air conditioning system
and the air conditioning automatically
shuts off. If this happens, take your ve-
hicle to your Toyota dealer for service. For economical and environmentfriend-
ly use
Usually, use the air conditioning with the
“A/C” button on (economical and environ-
ment
−friendly cooling).
In this mode the gasoline engine starts
and stops automatically and good fuel
economy driving is achieved.
To use the air conditioning in economi-
cal and environmentfriendly way, we
recommend the following setting: 1. Lower the setting temperature if you feel a little hot with the “A/C” button
on.
2. If you feel still hot with the “A/C” but- ton on, push the “MAX” button also.
After the compartment cools, turn off
the “MAX” mode only.

SECTION 3

146
Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break−in. But following a few simple tips
for the first 1000 km (600 miles) can add
to the future economy and long life of
your vehicle:
Do not drive over 100 km/h (62 mph).
Avoid full −throttle starts.
Try to avoid hard stops during the first
300 km (200 miles). FUEL TYPE
Your vehicle must use only unleaded
gasoline.
To help prevent gas station mixups, your To-
yota has a 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.
At a minimum, the gasoline you use
should meet the 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
effectiveness and the emission con-
trol system to function improperly.
Also, this can increase maintenance
costs.
OCTANE RATING
Select unleaded gasoline with an Oc-
tane Rating of 87 (Research Octane
Number 91) or higher. Use of unleaded fuel with an octane num-
ber or rating lower than stated above will
cause persistent 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 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
cause for concern.
GASOLINE CONTAINING DETERGENT
ADDITIVES
Toyota recommends the use of gasoline that
contains detergent additives to avoid build
up of engine deposits.
However, all gasoline sold in the U.S. con-
tains detergent additives
to keep clean and/or
clean intake systems.

QUALITY GASOLINE
Automotive manufacturers in the U.S., Eu-
rope and Japan have developed a specifica-
tion 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 levels. In the U.S., category 3 has
been adopted. The WWFC improves air
quality by providing for better emissions in
vehicle fleets, and customer satisfaction
through better vehicle performance.
CLEANER BURNING GASOLINE
Cleaner burning gasoline, including refor-
mulated gasoline that contains oxygenates
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.
GASOLINE CONTAINING MMT
Some gasoline contain an octane en-
hancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of
gasoline that contains MMT. If fuel con-
taining MMT is 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. GASOLINE 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 this does
not rectify your problem, then consult your
Toyota dealer.
NOTICE

Do not use gasohol other than
stated above. It will cause fuel sys-
tem damage or vehicle performance
problems.
 If drivability problems are encoun-
tered (poor hot starting, vaporizing,
engine knock, etc.), discontinue its
use.
 Take care not to spill gasohol dur-
ing refueling. Gasohol may cause
paint damage.
