(c) Front Passenger ’s Seat Belt
Reminder Light and Buzzer
The light and buzzer act as a reminder to
have the front passenger buckle up the
seat belt.
Once the engine switch is turned to “ON”
or “START”, the reminder light flashes 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 continues flashing.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for 30 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 90 more seconds. Even if the vehicle
speed drops below 20 km/h (12 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. If the buzzer
still sounds, make sure the driver ’s seat
belt is fastened.
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 and buzzer to sound.
(d) Charging System Warning Light
This warning light comes on when the
engine switch is turned to the “ON” posi-
tion, and goes off when the engine is
started.
When there are problems in the charging
system while theengine is running, the
warning light comes on.
NOTICE
When the charging system warning
light comes on while the engine is
running, malfunctions such as the en-
gine drive belt being broken may have
occurred. If the warning light comes
on, immediately stop the vehicle in a
safe place and contact any authorized
Toyota dealer or repairer, or another
duly qualified and equipped profes-
sional.
(e) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If the engine oil pressure warning light
comes on, pull off the road to a safe
place and stop the engine immediately.
Call any authorized Toyota dealer or re-
pairer, or another duly qualified and
equipped professional, for assistance. The
“STOP” warning light also comes on at
thesametime.
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 engine
oil level is extremely low. It is not de-
signed to indicate low engine oil level, and
the engine oil level must be checked us-
ing the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.

(f) Malfunction Indicator Lamp
This lamp warns that there is a problem
somewhere in your engine electrical sys-
tem.
If it comes on while you are driving, have
your vehicle checked/repaired by any au-
thorized Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional, as soon as possible.
On some models—
This lamp comes on in the following
cases.
a. There is a problem somewhere in your
engine, automatic transmission electri-
cal system or electronic throttle control
system.
b. The fuel tank is completely empty.
(See “Fuel gauge” on page 124 in this
Section for instructions.)
If it comes on while you are driving in
case a, have your vehicle checked/re-
paired by any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional, as soon as pos-
sible.
Vehicles with multi−mode manual transmis-
sion or vehicle stability control system—
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your Toyota
checked by any authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional, as soon as pos-
sible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, thesystem may not be
recovered until the engine is stopped and
the engine switch is turned to “ACC” or
“LOCK” position.CAUTION
Be especially careful to prevent erro-
neous pedal operation.
(g) “STOP” Warning Light
This light will come on when the engine
switch is turned to the “ON” position. After
a few seconds, the light will blink. When
the engine is started, the light will go off.
This means thesystem of the “STOP”
warning operating properly.
This light blinks in the following cases:
DWhen the engine coolant temperature
becomes high and the engine coolant
temperature warning light blinks. If the
engine coolant temperature rises fur-
ther, the engine coolant temperature
warning light remains on and at the
same time, the “STOP” warning light
blinks. In such cases, the engine is too
hot. If your vehicle overheats, stop the
vehicle and allow the engine to cool
down.
DWhen the engine oil pressure is too
low, the low engine oil pressure warn-
ing light comes on and at the same
time, the “STOP” warning light blinks.
In this case, pull off the road to a safe
place and stop the engine immediately.
Call any authorized Toyota dealer or re-
pairer, or another duly qualified and
equipped professional, for assistance.
(h) Low Fuel Level Warning Light and
Buzzer
The warning light blinks and the warning
buzzer comes on when the fuel level in
the tank becomes nearly empty. Fill up
the tank as soon as possible.
On incline or curves, due to the move-
ment of fuel in the fuel tank, the warning
light may blinks and the warning buzzer
may come on earlier than usual.

INFORMATION BEFORE DRIVING YOUR TOYOTA199
FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are as
follows.
DOil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil
is left on the cylinder wall when a pis-
ton moves downwards in the cylinder.
High negative pressure generated when
the vehicle is decelerating sucks some
of this oil into the combustion chamber.
This oil as well as some part of the oil
film left on the cylinder wall is burned
by the high temperature combustion
gases during the combustion process.
DOil is also used to lubricate the stems
of the intake valves. Some of this oil
is sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high−speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.Oil consumption:Max. 1.0 L per 1000
km (1.1 qts./600 miles, 0.9 lmp.qts./600
miles)
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately.
As an example, if a vehicle is used for
repeated short trips, and consumes a nor-
mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This
is because the oil is gradually becoming
diluted with fuel or moisture, making it
appear that the oil level has not changed.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it
appear that oil has been excessively con-
sumed while driving at high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see “Checking the engine oil level” on
page 264 in Section 7−2.

Winter driving tips
Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life hy-
brid organic acid technology. (Coolant with
long−life hybrid organic acid technology is
a combination of low phosphates and or-
ganic acids.)
See “Checking the engine coolant level”
on page 267 in Section 7−2 for details of
coolant type selection.
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about−35_C(−31_F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7−3 tells you how to visually
inspect the battery. Any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, will be
pleased to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 264 in Section 7−2forrecom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may make starting harder. If you
are not sure about which oil to use, call
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional, they will be pleased to help.
Keep the door locks from freezing.
Squirt lock de−icer or glycerine into the
locks to keep them from freezing.Use a washer fluid containing an anti-
freeze solution.
This product is available at any authorized
Toyota dealer or repairer and most auto
parts stores or another qualified profes-
sional. Follow the manufacturer ’s direc-
tions for how much to mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“M(1)”, “E(1)” or “R” (multi−mode manual
transmission), or into first or reverse
(manual transmission) and block the rear
wheels. Do not use the parking brake,
snow or water accumulated in and around
the parking brake mechanism may freeze,
making it hard to release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, a window scraper,
a bag of sand or salt, flares, a small
shovel, jumper cables, etc.

Checking the engine oil level
MS72006a
Low level Full level
Add oil O.K. Too full
With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick.
1. To get a correct reading, the vehicle
should be on level ground. After turning
off the engine, wait more than 5 min-
utes for the oil to drain back into the
bottom of the engine.
2. Pull the dipstick out, hold a rag under
the end and wipe it clean.
3. Reinsert the dipstick—push it in as far
as it will go, or the reading will not be
correct.
4. Pull the dipstick out and look at the oil
level while holding a rag under the
end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
NOTICE
Be careful not to drop engine oil on
the vehicle components.
If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler cap and add engine
oil in small quantities at a time, checking
the dipstick. We recommend that you use
a funnel when adding oil.
The approximate quantity of oil needed to
raise the level between low and full on the
dipstick is indicated as follows:
1.5L(1.6 qt.,1.3 Imp. qt.)
For the engine oil capacity, see “Service
specifications” on page 294 in Section 8.
When the level reaches within the correct
range, install the filler cap hand−tight.
NOTICE
zBe careful not to spill engine oil on
the vehicle components.
zAvoid overfilling, or the engine
could be damaged.
zCheck the oil level on the dipstick
once again after adding the oil.
