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 151.
Tachometer
15B003
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator get segment
into the red zone. This may cause
severe engine damage.
Odometer and two trip meters
15B004
This meter displays the odometer and
two trip meters.
1. Odometer—Shows the total distance the vehicle has been driven.
2. Two trip meters—Show two different distances independently driven since
the last time each trip meter was set
to zero.
You can use one trip meter to calculate
the fuel economy and the other to
measure the distance on each trip. All
trip meter data are cancelled if the
electrical power source is discon-
nected.

(a) Brake System Warning Light
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
When the parking brake is applied...
This light comes on for a few seconds
when the ignition key is turned to the
“ON” position even after the parking brake
is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Scion dealer in the following cases:
The light does not come on even if the
parking brake is applied when the igni-
tion key is in the “ON” position.
The light does not come on even if the
ignition key is turned on with the park-
ing brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Scion dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will increase. Depress the
brake pedal firmly and bring the ve-
hicle to an immediate stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver’s Seat Belt Reminder Light and Buzzer
This light and buzzer remind you to
buckle up the driver’s seat belt.
Once the ignition key is turned to the
“ON” or “START” position, the reminder
light and buzzer come on if the driver’s
seat belt is not fastened. Unless the driv-
er fastens the belt, the light keeps flash-
ing and the buzzer sounds for about 5
seconds.

81
(c) Front Passenger ’s Seat BeltReminder Light
This light reminds you to buckle up the
front passenger ’s seat belt.
Once the ignition key is turned to the
“ON” or “START” position, the reminder
light comes on if a passenger sits in the
front passenger seat and does not fasten
the seat belt. Unless the front passenger
fastens the belt, the light keeps flashing.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built −in sensors in the seat cushion may
detect the pressure, causing the reminder
light to flash. (d) Engine Oil Replacement Reminder
Light
This light reminds you when to replace
the engine oil.
This light will come on when the ignition
key is turned to the “ON” position, and
will go off after a few seconds.
When you drive for about 8000 km (5000
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
after the ignition key is turned to the “ON”
position. If you continue driving without
engine oil replacement, and if the driving
range exceeds 12000 km (7500 miles), the
light will come on when the ignition key
is turned to the “ON” position. The light
will remain on thereafter.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace it as soon as possible.
The system must be reset after the en-
gine oil replacement. Reset the system by
following the procedure below: 1. Turn the ignition key to the “OFF” posi- tion with the odometer reading shown.
(For details, see “Odometer and two
trip meters” on page 75.) 2. Turn the ignition key to the “ON” posi-
tion while holding down the trip meter
reset knob.
Hold down the knob for at least 5 sec-
onds. The light goes off, and the display
shows zero for 1 second and changes to
the odometer reading.
If the system fails to reset, the light will
remain on or keep flashing.
(e) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Scion dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.

82
(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on, 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 sev-
eral 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 Diagnostics)
system before taking your vehicle for the
inspection.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 182.
(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.

84
(l) 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 ignition
key is turned to the “ON” position. After
a few seconds, the light will go off.
If your engine coolant temperature is cool
with the ignition 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 151.
(m) “VSC” Warning Light
The light warns that there is a problem
somewhere in the vehicle stability control
system or traction control system.
The light will come on when the ignition
key is turned to the “ON” position, and
will go off after a few seconds.
If the light comes on while you are driv-
ing, the vehicle stability control system
and traction control system do not work.
However, as conventional braking operates
when applied, there is no problem to con-
tinue your driving.
In the following cases, contact your Scion
dealer:
The light does not come on when the
ignition key is turned to the “ON” posi-
tion.
The light remains on when the ignition
key is turned to the “ON” position.
The light comes on while you are driv-
ing.
