SEATS, SEAT BELTS, STEERING WHEEL AND MIRRORS39
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 airbag is operating
properly.
This warning light system monitors the
airbag sensor assembly, airbag sensor,
driver ’s seat belt pretensioner assembly,
inflator, interconnecting wiring and power
sources. (For details, see “Service
reminder indicators and warning buzzer”
on page 73 in Section 1−5.)The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
The SRS airbag will deploy in the event
of an impact that exceeds the set thresh-
old level (the level of force corresponding
to an approximately 20−30 km/h [12−18
mph] frontal collision with a fixed wall that
does not move or deform).
If the severity of the impact is below the
above threshold level, the SRS airbag
may not deploy.
However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if it is involved in an underride
collision (e.g. a collision in which the nose
of the vehicle “underrides”, or goes under,
the bed of a truck, etc.).
It is possible that in some collisions at the
lower zone of airbag sensor detection and
activation the SRS airbag and seat belt
pretensioner will not operate all together.
For the safety of all occupants, always
wear your seat belts properly.

SEATS, SEAT BELTS, STEERING WHEEL AND MIRRORS43
This SRS airbag system has a service
reminder indicator to inform the driver of
operating problems. If either of the follow-
ing conditions occurs, this indicates a mal-
function of the airbag. Contact any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional,
as soon as possible to service the ve-
hicle.
DThe light does not come on when the
engine switch is turned to the “ON”
position or remains on for more than
6 seconds or flashes.
DThe light comes on or starts flashing
while driving.
In the following cases, contact any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional,
as soon as possible:
DThe SRS airbag has been inflated.
DThe front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the SRS airbag to inflate.
DThe pad section of the steering wheel
(shaded in theillustration) is scratched,
cracked, or otherwise damaged.

The gauge indicates the approximate
quantity of fuel remaining in the tank
when the engine switch is on.
Nearly full—Needle at “F”
Nearly empty—Needle at “E”
It is a good idea to keep the tank over
1/4 full.
The needle moves when braking, acceler-
ating or making turns. This is caused by
the movement of the fuel in the tank.
If the fuel level approaches “E” or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
On some models—
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, as soon
as possible.The gauge indicates the engine coolant
temperature when the engine switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone,
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:
DDriving up a long hill on a hot day.
DReducing speed or stopping after high
speed driving.
DIdling for a long period with the air
conditioning on in stop−and−go traffic.
DTowingatrailer.
NOTICE
zDo 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.
zDo not continue driving with an
overheated engine. See “If your ve-
hicle overheats” on page 156 in
Section 4.

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 over−revving.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
For better fuel economy, keep the needle
within the economy (green) zone. Driving
with the engine running too fast causes
excessive engine wear and poor fuel
economy.

70GAUGES, METERS AND SERVICE REMINDER INDICATORS
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 is cancelled if the elec-
trical power source is disconnected.
3. Trip meter reset knob—Resets the two
trip meters to zero, and also change
the meter display.
To change the meter display, quickly
push and release the knob. The meter
display changes in the order from the
odometer to trip meter A to trip meter
B, then back to the odometer each
time you push.
To reset the trip meter A to zero, dis-
play the meter A reading, then push
and hold the knob until the meter is
set to zero. The same process can be
applied for resetting the trip meter B.The oil maintenance management sys-
tem (OMMS) is designed to inform you,
by means of a light, of the time to
change the engine oil and oil filter.
ENGINE OIL AND OIL FILTER CHANGE
Change the engine oil and oil filter in
either of the following cases:
DWhen the engine oil change reminder
light is lit.
DWhen the system is repaired.
DWhen the engine oil change reminder
light does not come on even if two
years have passed since the engine
oil was changed.
DWhen the engine oil change reminder
light does not come on even if you
have driven over 30000 km (18000
miles) since the engine oil was
changed.
The lighting timing will change according
to the driving condition.
Because engine oil deteriorates over
time, there are cases when it is neces-
sary to change the engine oil before
the engine oil change reminder light
comes on. In these cases, change the
engine oil and oil filter according to the
maintenance schedule. (For engine oil
maintenance intervals, see the separate
“Toyota Service Booklet” or “Toyota
Warranty Booklet”.)

ENGINE OIL CHANGE REMINDER LIGHT
This light comes on when the engine
switch is turned to the “ON” position. It
goes out after about 3 seconds. This indi-
cates that the system is functioning nor-
mally. If the light illuminates for 3 seconds
and then flashes for about 12 seconds,
this indicates that the time to change the
engine oil is approaching.
If this light stays on this warns you to
change the engine oil and oil filter us-
ing appropriate replacements at your
earliest convenience. For more informa-
tion about oil grade and viscosity, see
“Checking the engine oil level” on page
196 in Section 7−2.

be sure to reset the system, so that the
light goes out. (For instructions on reset-
ting the system, see “RESETTING THE
SYSTEM” on page 72 in this Section.)
The system must also be reset if an en-
gine oil and oil filter change is performed
before the light comes on. If you do not
reset the system, it cannot inform you of
the correct time to change the engine oil
and oil filter.If any of the following occurs, the
system may not be functioning normal-
ly. Have the vehicle checked at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
DWhen the engine switch is turned to
the “ON” position, the light does not
come on.
