(f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. 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.
(g) Low Engine Oil Pressure WarningLight
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
Toyota 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.
(h) “ABS” Warning Light
Vehicles without the vehicle stability
control system—
The light comes on when the ignition key
is turned to the “ON” position. If the anti −
lock brake system works properly, the
light turns off after a few seconds. There-
after, 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 system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
but the brake assist system still operates.
In this case, the wheels could lock up
during a sudden braking or braking on
slippery road surfaces. If either of the following conditions
occurs, this indicates a malfunction
somewhere in the components moni-
tored by the warning light system. Con-
tact your Toyota dealer as soon as
possible to service the vehicle.The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

(k) “VSC” Warning Light
This 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 “ON” and will go off after
a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
Tw o −wheel drive models only—The “TRAC
OFF” indicator light will come on when the
“VSC” warning light comes on even if the
“TRAC OFF” switch is not pushed. (l) Low Tire Pressure Warning Light
This light warns that the tire pressure of
any one of the tires is critically low. The
light comes on when the ignition key is
turned to the “ON” position. It goes off
after a few seconds. This indicates that
the low tire pressure warning system is
functioning properly.
If the light comes on while driving, adjust
tire inflation pressure to the specified lev-
el. (See “Tires” on page 491 in Section 8.)
After the tire inflation pressure is adjusted,
the light should go off after driving at
least 30 km/h (19 mph) for some time. If
the light still remains or blinks once every
second, have the low tire pressure warn-
ing system checked at your Toyota dealer.
If the light blinks twice every second, the
low tire pressure warning system needs to
be initialized.
For details, see “Tire pressure warning
system” on page 188 in Section 1
−6.
(m) Low Windshield Washer Fluid Level Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see “Adding washer fluid” on page 479 in
Section 7 −3.) (n) Engine Oil Replacement Reminder
Light (for vehicles sold in U.S.A.)
This light reminds you when to replace
the engine oil.
This light will come on when the ignition
key is turned to “ON” and will go off after
about 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
with the ignition key turned to the “ON”
position. If you continue driving without
replacing the engine oil, and if the dis-
tance driven exceeds 12000 km (7500
miles), the light will come on after the
ignition key is turned to “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
the following procedure:1. Turn the ignition key to the “ACC” or “LOCK” position with the odometer
reading shown. (For details, see
“Odometer and two trip meters” on
page 166 in this Section.)
2. Turn the ignition key to the “ON” posi- tion while holding down the trip meter
reset button.
Hold down the button for at least 5 sec-
onds. The odometer indicates “000000”
and the light goes off.
If the system fails to reset, the light will
continue flashing. (o) Dynamic Laser Cruise Control Mas-
ter Warning Light
This light warns that there is a problem
somewhere in the dynamic laser cruise
control system.
The light will come on when the ignition
key is turned to “ON” and go off after a
few seconds.
When the light comes on, the alarm
sounds and the warning code will appear
on the display. At this time, dynamic laser
cruise control is cancelled. For details,
see “Dynamic laser cruise control” on
page 195 in Section 1 −6.
(p) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver’s door with
the ignition key in the “ACC” or “LOCK”
position. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light
and low windshield
washer fluid level warning light)
1. Apply the parking brake.
2. Open one of the doors. The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Turn the ignition key to “ON”, but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light should
come on. The “ABS” and “VSC” warn-
ing lights, low tire pressure warning
light, dynamic laser cruise master
warning light and engine oil replace-
ment reminder light go off after a few
seconds. The SRS warning light goes
off after about 6 seconds. (“TRAC
OFF”, “READY” (dynamic laser cruise
ready mode) indicator lights and slip
indicator light also comes on and go
off after a few seconds.)

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 qt./600 miles, 0.9 Imp. qt./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 express way, making it
appear that oil is excessively consumed
after 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 456 in Section 7
−2.
Your engine is fitted with iridiumtipped
spark plugs.
NOTICE
Use only iridiumtipped spark plugs
and do not adjust gaps for your en-
gine performance smooth driveabili-
ty.

Make sure your coolant is properly pro-
tected against freezing.
Your coolant must contain ethylene−glycol
type coolant for a proper corrosion
protection of aluminum components. Use
“Toyota Genuine Long Life Coolant” or
equivalent.
See page 458 in Section 7 −2 for details
about coolant type selection.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
When it is extremely cold, we recommend
to use 60% solution for your Toyota, to
provide protection down to about −50 C
( − 58 F). Do not use more than 70% solu-
tion for better coolant performance.
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. Your Toyota dealer
and most service stations will be pleased
to check the level of charge. Make sure the engine oil viscosity is
suitable for the cold weather.
See page 456 in Sec t i on 7
−2 for recom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may cause harder starting. If you
are not sure about which oil to use, call
your Toyota dealer—he 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 your Toyota
dealer and most auto parts stores. Follow
the manufacturer ’s directions 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
“P” and block the rear wheels. Do not use
the parking brake, or snow or water accu-
mulated 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, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.

If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably 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 “P”
and apply 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 ignition 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 theradiator, 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.
4. If the coolant is leaking, stop the en-gine immediately. Call a Toyota dealer
for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
6. After the engine coolant temperaturehas cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Toyota dealer.

4. Loosen all the wheel nuts.
Always loosen the wheel nuts before
raising the vehicle.
Turn the wheel nuts counterclockwise
to loosen. To get maximum leverage,
fit the wrench to the nut so that the
handle is on the right side, as shown
above. Grab the wrench near the end
of the handle and pull up on the han-
dle. Be careful that the wrench does
not slip off the nut.
Do not remove the nuts yet—just un-
screw them about one −half turn.
CAUTION
Never use oil or grease on the
bolts or nuts. The nuts may loose
and the wheels may fall off,
which could cause a serious ac-
cident.
CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury:
 Follow jacking instructions.
 Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.
 Do not start or run the engine
while your vehicle is supported
by the jack.
 Stop the vehicle on a level firm
ground, firmly set the parking
brake and put the transmission
in “P”. Block the wheel diago-
nally opposite to the one being
changed if necessary.
