ENGINE (IGNITION) SWITCH, TRANSMISSION AND PARKING BRAKE147
MS16010a
(a) Upshift and downshift
Upshifting
Pull the shift lever to the “+” direction
and release it. Every time the lever is
operated, the transmission is upshifted
1 step in the order of 1st→2nd→
3rd→4th→5th gear.
Downshifting
Push the shift lever to the “−” direction
and release it. Every time the lever is
operated, the transmission is down-
shifted in the order of 5th→4th→
3rd→2nd→1st gear.
DTo shift down smoothly, the engine
runs fast in some cases. This is done
intentionally by the system and is not
a malfunction.
DWhen driving down a hill, downshift
and use the engine brakes appropriate-
ly. If necessary, continuous shifting
down is possible. However, if down-
shifting more than 3 steps continuously,
the gear shifting will take more time.
DWhen the outside air temperature is
extremely low, the gear may not down-
shift from 2nd to 1st until the vehicle
stops.
DWhen the gear is shifting, a noise can
be heard in some case. This is not a
malfunction.
DIn case the transmission cannot be en-
gaged to a certain gear position during
shifting due to mechanical malfunction,
the gear will not be engaged and re-
mains in neutral. The “N” in the gear
position indicator will blink and a warn-
ing buzzer (long pulse sound) will
sound until the driver shifts the shift
lever to “N” position.
Unless the system recovers from the
above−mentioned condition (mechanical
malfunction), the gear will still remain
in neutral position even shifting the
shift lever to “M” or “E” position after
the system performs a re−try shifting.
If such conditions continue, contact any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional, as soon as possible to
service the vehicle.
DWhen the gear jumped out of position
while driving, the gear is shifted to
proper gear position.
NOTICE
Manual (M) mode dose not shift up
the gear even if the engine speed
reaches the rev−limit.

AUDIO SYSTEM169
SCAN
There are two scan features—you can ei-
ther scan the tracks on a specific disc or
scan the first tracks of all the discs in the
magazine.
Scanning the tracks on a disc:
Quickly push and release “SCAN”. “SCAN”
will appear on the display and the player
will scan all the tracks on the disc you
are listening to. If you hear a beep, you
held the button too long, and the player
will scan the first tracks of all the discs
in the magazine. To select a track, push
the “SCAN” a second time. If the player
scanned all the tracks on the disc, it will
stop scanning.
Compact disc changer only—
Scanning for the first tracks of all the
discs in the magazine:
Push and hold “SCAN” until you hear a
beep. “D−SCAN” will appear on the dis-
play and the player will perform the first
track of the next disc. To select a disc,
push the “SCAN” a second time. If the
player has scanned all the discs, it will
stop scanning.
ST (Stereo reception) display
Your radio automatically changes to stereo
reception when a stereo broadcast is re-
ceived. “ST” appears on the display. If the
signal becomes weak, the radio reduces
the amount of channel separation to prev-
ent the weak signal from creating noise.
If the signal becomes extremely weak, the
radio switches from stereo to mono recep-
tion.TA (Traffic Announcement)
This button is used for receiving TA sta-
tions all over the band.
EON (Enhanced Other Network) sys-
tem—If the RDS station (with EON data)
you are listening to is not broadcasting a
traffic information program at the TA (Traf-
fic Announcement) mode, the radio will be
switched to the traffic information program
automatically by using the EON AF list.
After the traffic information ends, the radio
will return to the initial program automati-
cally. A beep will sound to tell you when
this feature starts and ends the operation.
When receiving FM:
Push “TA” to switch the radio mode to TP
(Traffic Program). “TP” will appear on the
display.
In the TP mode, the radio will begin seek-
ing a TP station. If the radio seek out a
TP station, the program name will appear
on the display. If the TA station is re-
ceived, the radio will be switched to the
traffic information program automatically.
When the program ends, the initial opera-
tion resumes. When also in AF mode, the
radio will seek a TP station by using the
AF list.
Push “TA” once again to switch the radio
mode to TA. “TA” will appear on the dis-
play and the radio will mute the volume
of FM station.
In the TA mode, the radio will begin seek-
ing a TP station. It sounds only when a
TP station is received. When a TP station
is received, the program service name will
appear on the display. In the AF mode,
the radio will also begin seeking a TP
station by using the AF list.
While the radio is seeking a TP station,
“TP SEEK” appears on the display. If the
radio cannot seek out any TP stations,
“NOTHING” will appear on the display for
2 seconds and the radio will begin seek-
ing a TP station again.

AIR CONDITIONING SYSTEM185
The air conditioning filter may clog af-
ter long term use. The filter may need
to be replaced if the air flow of the air
conditioning and heating and defrosting
experiences extreme reductions in oper-
ating efficiency, or if the windows begin
to fog up easily.
To maintain the air conditioning efficiency,
inspect and replace the air conditioning
filter according to the maintenance sched-
ule. (For scheduled maintenance informa-
tion, please refer to the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.)
MS18010a
1. Pull out the air conditioning filter as
shown in the illustration.
2. Inspect the filter on the surface.
If it is dirty, it should be replaced.
INFORMATION
The air filter should be installed prop-
erly in position. The use of air condi-
tioning with the air filter removed
may cause deteriorated dustproof per-
formance and then affect air condi-
tioning performance.

INFORMATION BEFORE DRIVING YOUR TOYOTA197
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
DKeep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
DDo 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 gases
flowing into the three−way catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
zUse only unleaded gasoline.
zDo not drive with an extremely low
fuel level; running out of fuel could
cause the engine to misfire, creat-
ing an excessive load on the three−
way catalytic converter.
zDo not allow the engine to run at
idle speed for more than 20 min-
utes.
zAvoid racing the engine.
zDo not push−start or pull−start your
vehicle.
zDo not turn off the engine while the
vehicle is moving.
zKeep your engine in good running
order. Malfunctions in the engine
electrical system, electronic ignition
system/distributor ignition system
or fuel system could cause an ex-
tremely high three−way catalytic
converter temperature.
zIf the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check−up to any
authorized Toyota dealer or repairer,
or another duly qualified and
equipped professional.
zTo ensure that the three−way
catalytic converter and the entire
emission control system operate
properly, your vehicle must receive
the periodic inspections required by
the Toyota Maintenance Schedule.
For scheduled maintenance
information, refer to the “Toyota
Service Booklet” or “Toyota
Warranty Booklet”.

BRAKE ASSIST SYSTEM
When you slam the brakes on, the
brake assist system judges as an emer-
gency stop and provides more powerful
braking for a driver who cannot hold
down the brake pedal firmly.
When you slam the brakes on, more pow-
erful braking will be applied. At this time,
you may hear a sound in the engine
compartment and feel the vibrations of the
brake pedal. This does not indicate a mal-
function.Vehicles with vehicle stability control sys-
tem—
The brake assist system becomesopera-
tive after the vehicle has accelerated to a
speed in excess of approximately 10 km/h
(6 mph). It stops operating when the ve-
hicle decelerates to a speed below
approximately 5 km/h (3 mph).
