If the system fails to reset, the light will
remain on or keep flashing.
(f) Malfunction Indicator Lamp
This lamp comes on when the engine
switch is turned to the “ON” position
and goes off after the engine starts.
This means that the warning light sys-
tem is operating properly.
If the lamp remains on or the lamp
comes on while driving, first check the
following.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp will not go off even after
the several trips, contact your Scion
dealer as soon as possible. If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, auto-
matic transmission electrical system or
warning light system itself.
Contact your Scion dealer as soon as
possible to service the vehicle.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Scion deal-
er to check your vehicle’s emission control
system and OBD (On–Board Di agnostics)
system before taking your vehicle for the
inspection.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 226.
(g) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes very low. Fill up the
tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual. (h) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Scion dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.

11 2
(i) “ABS” Warning Light
The light comes on when the engine
switch is turned to the “ON” position. If
the anti–lock brake system works properly,
the light turns off after a few seconds.
Thereafter, if the system malfunctions, the
light comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti–lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti–lock brake system does not operate
so that the wheels could lock up during
sudden braking or braking on slippery
road surfaces.
If any of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Scion dealer as soon as possible to
service the vehicle.The light does not come on when the
engine switch is turned to the “ON”
position, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Scion dealer.
In this case, not only the anti–lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(j) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed. (k) SRS Warning Light
This indicator comes on when the en-
gine switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the SRS front airbags, SRS
side airbags, curtain shield airbags and
seat belt pretensioners are operating
properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger occupant classification system,
“AIR BAG ON” indicator light, “AIR BAG
OFF” indicator light, front passenger ’s seat
belt buckle switch, seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources.
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Scion dealer as soon as possible.
When the engine switch is turned to
the “ON” position, the light does not
come on or remains on for more than
6 seconds.
The light comes on while driving.

11 3
The SRS warning light and “AIR BAG
OFF” indicator light will come on if there
is a malfunction in the front passenger
occupant classification system.
(l) Tire Pressure Warning Light
This light comes on when the engine
switch is turned to the “ON” position. If
the tire pressure warning system works
properly and tire inflation pressure is ap-
propriate, the light goes off after a few
seconds.
This light comes on or comes on after
blinking for 1 minute in the following
cases when the engine switch is turned to
the “ON” position.
When a low tire inflation pressure is
detected while driving...
If any tire has low inflation pressure,
the light comes on.
The light goes off after the tire inflation
pressure is adjusted to a specified lev-
el.
When initializing the system...
If initialization is accepted, the light
blinks slowly three times.
When the system malfunctions...
If the system malfunctions, the light
comes on after blinking for 1 minute.Although it is no problem to continue
driving, have your vehicle checked by
your Scion dealer as soon as possible.
(m) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key when you open the driver’s door
with the engine switch in the “ACC” or
“LOCK” position. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light)
1. Apply the parking brake.
2. Open either side door or back door. The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Turn the engine switch to the “ON” position, but do not start the engine.
All the service reminder indicators except
the open door warning light should come
on. The “ABS” warning light, “MAINT
REQD” reminder light and tire pressure
warning light go off after a few seconds.
The SRS warning light goes off after
about 6 seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Scion
dealer as soon as possible.

“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see page 184.
“ON”—Engine on and all accessories
on.
This is the normal driving position.
“ACC”—Accessories such as the radio
operate, but the engine is off.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key.“LOCK”—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
You must push in the key to turn the
engine switch from “ACC” to the “LOCK”
position. On vehicles with an automatic
transmission, the shift lever must be put
in the “P” position before pushing the key.
When starting the engine, the key may
seem stuck at the “LOCK” position. To
free it, first be sure the key is pushed all
the way in, and then rock the steering
wheel slightly while turning the key gently.
Approximately five hours after the engine
is turned off, you may hear a sound com-
ing from underneath the luggage compart-
ment for several minutes. This is normal
operation and does not indicate a malfunc-
tion. (See “Leak detection pump” on page
viii.)
CAUTION
For vehicles with manual transmis-
sion:
Never remove the key when the ve-
hicle is moving, as this will lock the
steering wheel and result in loss of
steering control.
NOTICE
Do not leave the key in the “ON”
position if the engine is not running.
The battery will discharge and the
ignition could be damaged.

Automatic transmission
Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only move out of “P” position when the
brake pedal is depressed (with the engine
switch in “ON” position).
(a) Shift lever
The shift position is displayed on the in-
strument cluster.
P: Parking, engine starting and key re-
moval
R: Reverse
N: Neutral
D: Normal driving (with overdrive on)
3: Engine braking
2: Stronger engine braking
L: Maximum engine braking
Shift with the brake pedal
depressed.
(The engine switch must be in
“ON” position.)
Shift normally.

11 8
(b) Normal driving1. Start the engine as instructed in “How to start the engine” on page 184. The
transmission must be in “P” or “N”.
2. With your foot holding down the brake pedal, shift the shift lever to “D”.
When the lever is in the “D” position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, etc.
Always use the “D” position for better fuel
economy and quieter driving. If the engine
coolant temperature is low, the transmis-
sion will not shift into the overdrive gear
even in the “D” position.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake pedal. Depress the accelerator pedal
slowly for smooth starting. (c) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Shift into the “3” position. The trans-
mission will downshift to third gear, and
engine braking will be enabled.
Shift into the “2” position. The trans-
mission will downshift to second gear
when the vehicle speed drops down to
or lower than 108 km/h (67 mph), and
stronger engine braking will be en-
abled.
Shift into the “L” position. The trans-
mission will downshift to first gear
when the vehicle speed drops down to
or lower than 54 km/h (34 mph), and
maximum engine braking will be en-
abled.
When the cruise control is being used,
even if you down shift from “D” to “3”,
engine braking will not be enabled be-
cause the cruise control is not cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” on page 127.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
(d) Using “2” and “L” positions
The “2” and “L” positions are used for
strong engine braking as described pre-
viously.
With the shift lever in “2” or “L”, you can
start the vehicle in motion as with the
lever in “D”.
With the shift lever in “2”, the vehicle will
start in first gear and automatically shift
to second gear.
With the shift lever in “L”, the transmis-
sion is engaged in first gear.

11 9
NOTICE
Be careful not to over–rev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:
“2” 108 km/h (67 mph) . . . . . . . . .
“ L” 60 km/ h ( 37 mph)
. . . . . . . . . .
 Do not continue hill climbing for a
long time in the “2” or “L” posi-
tion. This may cause severe auto-
matic transmission damage from
overheating. To prevent such dam-
age, “D” position should be used in
hill climbing.
(e) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the shift lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(f) Parking
1. Bring the vehicle to a complete stop.
2. Pull the parking brake lever up fully to securely apply the parking brake.
3. With the brake pedal pressed down, shift the shift lever to the “P” position.
CAUTION
Never attempt to move the shift lever
into “P” position under any circum-
stances while the vehicle is moving.
Serious mechanical damage and loss
of vehicle control may result.
(g) Good driving practice
If the transmission repeatedly shifts up
and down between third gear and over-
drive when climbing a gentle slope, shift
the shift lever to the “3” position. Be sure
to shift the shift lever to the “D” position
immediately afterward.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Always use the brake pedal or the
parking brake to hold the vehicle on
an upgrade. Do not attempt to hold
the vehicle using the accelerator ped-
al, as this can cause the transmission
to overheat.

121
Good driving practice
If it is difficult to shift into reverse, put
the transmission in neutral, release the
clutch pedal momentarily, and then try
again.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
NOTICE
Do not rest your foot on the clutch
pedal while driving. Doing so may
cause clutch trouble.
 Do not use any gears other than
first gear when starting off and
moving forward. Doing so may dam-
age the clutch.
 Make sure the vehicle is completely
stopped before shifting into reverse.
The tire pressure warning system warns
you that the tire inflation pressure is
low.
The tire pressure warning system is not
a substitute for checking normal tire infla-
tion pressure. Check the tire inflation
pressure with a tire pressure gauge regu-
larly.
CAUTION
The warning system may not activate
immediately if blowout or sudden air
loss should occur.
17T004a
The tire pressure warning light comes on
when the engine switch is turned to the
“ON” position and goes off after a few
seconds. This means the tire pressure
warning light is operating properly. If the
tire inflation pressure becomes low, the
light comes on again. In this case, adjust-
ing the tire inflation pressure will turn off
the light after a few minutes. If the light
comes on after blinking for 1 minute, the
tire pressure warning system is not work-
ing properly.
