The warning lights indicate the engine
coolant temperature when the engine
switch is on. The engine operating tem-
perature will vary with changes in
weather and engine load.
The engine coolant temperature warning
light will come on when the engine switch
is turned to the “ON” position. After a few
seconds, the light will go off.
Engine coolant temperature is high...
When the engine coolant temperature be-
comes high, the engine coolant tempera-
ture warning light blinks. If the tempera-
ture rises further, 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.
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.
NOTICE
zDo not remove the thermostat from
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
vehicle overheats” on page 225 in
Section 4.

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.

engine overheating.
(j) “Multi−mode Manual Transmission”
Warning Light (Multi−mode manual
transmission only)
This light will come on when the engine
switch is turned to the “ON” position. After
a few seconds, the light will go off. This
means the multi−mode manual transmis-
sion system isoperating properly.
NOTICE
In case the Multi−mode manual trans-
mission warning light comes on, pull
over, stop the engine and contact any
authorized Toyota dealer or repairer,
or another duly qualified and
equipped professional. Otherwise, the
vehicle may jerk when shifted gear or
the clutch may not engage properly.
In some cases the shift requirement
may be canceled and the gear may be
locked.
(k) “ABS” Warning Light
Vehicles without vehicle stability control
system—
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 systemdoes not operate,
but the brake system stilloperates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake systemdoes not operate
so that the wheels could lock up during

STARTING AND DRIVING211
Before starting the engine, be sure to
follow the instructions in “(a) Before
cranking”.
Normal starting procedure
The multiport fuel injection system/sequen-
tial multiport fuel injection system in your
engine automatically controls the proper
air−fuel mixture for starting. You can start
a cold or hot engine as follows:
Multi−mode manual transmission:With
your foot off the accelerator pedal, turn
the engine switch to the “START” posi-
tion and crank the engine while depress-
ing the brake pedal. Release the key
when the engine starts. The engine can-
not be cranked if the shift lever is in a
position except “N” or the brake pedal
is not depressed.
Manual transmission:With your foot off
the accelerator pedal, crank the engine
by turning the engine switch to the
“START” position. Release it when the
engine starts.
Engine should be warmed up by driving,
not idling. For warming up drive with a
smoothly turning engine until the engine
coolant temperature is within the normal
range.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See “If your vehicle will not start” on page
220 in Section 4.
NOTICE
zDo not crank for more than 30 se-
conds at a time. This may overheat
the starter and wiring systems.
zDo not race a cold engine.
zIf the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Pre−trip safety check
It is a good idea to do a safety check
before starting out on a trip. A few min-
utes of checking can help ensure safe and
pleasant driving. Just a basic familiarity
with your vehicle is required and a careful
eye! Or, if you would like, any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional, will
be pleased to make this check for you at
nominal cost.
CAUTION
If you make this check in an enclosed
garage, make sure there is adequate
ventilation. Engine exhaust is poison-
ous.
BEFORE STARTING THE ENGINE
Outside the vehicle
Tires.Check the pressure with a gauge
and look carefully for cuts, damage, or
excessive wear.
Wheel bolts.Make sure no bolts are mis-
sing or loose.
Fluid leaks.After the vehicle has been
parked for a while, check underneath for
leaking fuel, oil, water, or fluid. (Water
dripping from the air conditioning after use
is normal.)
Lights.Make sure the headlights, stop
lights, tail lights, turn signals and other
lights are all working. Check the headlight
aim.
Inside the vehicle
Spare tire, jack and wheel bolt wrench.
Check the spare tire pressure and make
sure you have your jack and wheel bolt
wrench.

STARTING AND DRIVING215
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.

IN CASE OF AN EMERGENCY225
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.
If your high engine coolant temperature
warning light flashes to indicates over-
heating, if you experience a loss of
power, or if you hear a loud knocking
or pinging noise, the engine has prob-
ably overheated. You should follow this
procedure...
1. Pull safely off the road, stop the ve-
hicle and turn on your emergency
flashers. Put the transmission in “N”
(multi−mode manual transmission), or
neutral (manual transmission) and ap-
ply the parking brake. Turn off the air
conditioning if it is being used.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running and make sure the electric
cooling fan is operating. If it is not,
turn the engine switch off.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
