(p) High Engine Coolant TemperatureWarning Light
The light operates to warn that the engine
is almost overheating.
The high engine coolant temperature warn-
ing light will come on when the engine
switch is turned to the “ON” position. After
a few seconds, the light will go off.
If your engine coolant temperature is low
with the engine switch on, the low engine
coolant temperature indicator light comes
on. If it keeps lighting on with the engine
fully warmed, contact your Scion dealer as
soon as possible to service the vehicle.
If the high engine coolant temperature
warning light flashes, your engine is too
hot. If your vehicle overheats, stop your
vehicle and allow the engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air
conditioning on in stop −and− go traffic.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your
vehicle overheats” on page 205.
(q) 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.
(r) Light Reminder Buzzer
This buzzer will sound if the headlight
switch is left on and the driver’s door is
opened with the key removed from the
engine switch. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light and low windshield wash-
er fluid level warning light)
1. Apply the parking brake.
2. Open one of the side doors 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”, “VSC OFF”, tire pressure
warning light, electric power steering sys-
tem warning light, “MAINT REQD” remind-
er light, high engine coolant temperature
warning light and slip indicator light go off
after a few seconds. The SRS warning
light goes off after about 6 seconds.

“START”—Starter motor on. The engine
switch will return to the “ON” position
when released.
For starting tips, see page 190.
“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 engine switch 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 selector lever must be
put in the “P” position before pushing the
key.
When starting the engine, the engine
switch 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 5 hours after the engine is
turned off, you may hear a sound coming
from underneath the luggage compartment
for several minutes. This is normal opera-
tion and does not indicate a malfunction.
(See “Leak detection pump” on page viii.)
CAUTION
For manual transmission:
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 engine switch 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 shift out of “P” position when the
brake pedal is depressed (with the engine
switch in “ON” position).
(a) Selector lever
The shift position is also displayed on the
instrument cluster.
P: Parking, engine starting and key re-
moval
R: Reverse
N: Neutral
D: Normal driving
(shifting into overdrive possible)
3: Engine braking
(shifting into overdrive not possible)
2: Stronger engine braking
L: Maximum engine braking

(b) Normal driving1. Start the engine as instructed in “How to start the engine” on page 190. The
transmission must be in “P” or “N”.
2. With your foot holding down the brake pedal, shift the selector 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, hard towing, 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 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 97 km/h (60 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 47 km/h (29 mph), and
maximum engine braking will be en-
abled.
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 selector lever in “2” or “L”, you
can start the vehicle in motion as with the
lever in “D”.
With the selector lever in “2”, the vehicle
will start in first gear and automatically
shift to second gear.
With the selector lever in “L”, the trans-
mission is engaged in first gear.
NOTICE

Be careful not to overrev the en-
gine. The approximate maximum al-
lowable speed for each position is
given below for your reference:
“2” 118 km/h (74 mph) . . . . . . . . . .
“ L” 64 km/ h ( 40 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” or “3” position should be
used in hill climbing.

11 9
(e) Backing up1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector 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 selector lever to the “P” posi-
tion.
CAUTION
While the vehicle is moving, never
attempt to move the selector lever
into “P” position under any circum-
stances. Serious mechanical damage
and loss of vehicle control may re-
sult.
(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 selector lever to the “3” position. Be
sure to shift the selector 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.
(h) If you cannot move the selector le-
ver out of “P” position
If you cannot shift the selector lever from
“P” position even though the brake pedal
is depressed, use the shift lock override
button. For instructions, see “If you cannot
shift automatic transmission selector lever”
on page 221.

121
The traction control system automatical-
ly helps prevent the spinning of the
front wheels when the vehicle is started
or accelerated on slippery road sur-
faces.
When the engine switch is turned to “ON”
position, the system automatically turns
on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against front wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.
NORMAL DRIVING MODE
Leave the system on during ordinary
driving so that it can operate when
needed.
You may hear a sound in the engine
compartment for a few seconds just after
the vehicle begins to move. This means
that the traction control system is in the
self−check mode, but does not indicate a
malfunction. When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
front wheels. At this time, the slip indi-
cator light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to “ON” position. If the indicator light does
not come on when the engine switch is
turned on, contact your Scion dealer.

TRACTION CONTROL OFF MODE
If your wheels get stuck in a ditch
when you are driving on a severe off
road or sand, turn off the traction con-
trol system or vehicle stability control
system. (See page 124 to turn off the
vehicle stability control system.) These
systems control engine performance
that interferes with the process of free-
ing your wheels.

To turn off: Push “VSC OFF” switch
briefly.
The slip indicator light will come on.
When the engine switch is turned to “ON”
position, the traction control system and
vehicle stability control system always turn
on.
The traction control system turns back on
when the vehicle reaches to the certain
speed.
To turn on: Push “VSC OFF” switch
once again.
The slip indicator light will go off.
CAUTION
When the traction control and vehicle
stability control systems are off, be
especially careful and drive at a
speed appropriate to the road condi-
tions. As these are systems to ensure
vehicle stability and driving force, do
not turn off the traction control and
vehicle stability control systems un-
less necessary.
In the following cases, contact your Scion
dealer:
The slip indicator light does not come
on when the engine switch is turned to
“ON” position.
The slip indicator light remains on after
the engine switch is turned to “ON”
position.
The slip indicator light comes on in the
normal driving mode while driving.

123
The vehicle stability control system
helps provide integrated control of the
systems such as an antilock brake
system, traction control, engine control,
etc. This system automatically controls
the brakes and engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating steering wheel abruptly.
The vehicle stability control system is acti-
vated when the vehicle speed is about
more than 15 km/h (9 mph).
You may hear a sound in the engine
compartment for a few seconds just after
the vehicle begins to move. This means
that the system is in the self−check mode,
but does not indicate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively. Reck-
less driving will result in an unex-
pected accident and cause death or
serious injury. If the slip indicator
light flashes, sounding an alarm,
special care should be taken while
driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Scion dealer. (See
“Checking and replacing tires” on
page 252.)
In situations where the road surface
is covered with ice or snow, your
vehicle should be fitted with snow
tires or tire chains.
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to “ON” position. If the indicator light does
not come on when the engine switch is
turned on, contact your Scion dealer.
