SORS
HINT:
Perform the operation with the engine speeds and time durations described below prior to check the wave-
forms of the A/F and HO2 sensors. This is in order to activate the sensors sufficiently to obtain the appropri-
ate inspection results.
(a) Connect the hand±held tester to the DLC3.
(b) Start the engine and warm it up with all the accessories switched OFF, until the engine coolant temper-
ature stabilizes.
(c) Run the engine at an engine speed of between 2,500 rpm and 3,000 rpm for at least 3 minutes.
(d) After confirming that the waveform of the heated oxygen sensor (bank 1, 2 sensor 1 (HA1A, HA2A)),
oscillate around 0.5 V during feedback to the ECM, check the waveform of the heated oxygen sensor
(bank 1, 2 sensor 2 (OX1B, OX2B)).

CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
1. REMOVE ENGINE UNDER COVER
2. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
(b) Remove the 3 drain plugs on the engine and radiator, and
drain the coolant.
(c) Close the 3 drain plugs.
Torque: 12.7 N´m (130 kgf´cm, 9 ft´lbf) for engine
3. REFILL WITH ENGINE COOLANT
(a) Slowly fill the system with coolant.
Capacity: 11.6 liters (12.3 US qts, 10.2 Imp. qts)
NOTICE:
Do not use plain water alone.
HINT:

Use of improper coolants may damage the engine cooling
system.

Use ºToyota Super Long Life Coolantº or similar high qual-
ity ethylene glycol based non±silicate, non±amine, non±
nitrite, and non±borate coolant with long±life hybrid or-
ganic acid technology.

New Toyota vehicles are filled with Toyota Super Long
Life Coolant (color is pink, premixed ethylene glycol con-
centration is approximately 50 % and freezing tempera-
ture is ±35°C (±31°F)). When replacing the coolant, Toyo-
ta Super long Life Coolant is recommended.

Observe the coolant level inside the radiator by pressing
the inlet and outlet radiator hoses several times by hand.
if the coolant level goes down, add the coolant.
(b) Install the radiator cap.
(c) Bleed the cooling system.
(1) Start the engine, and open the heater water valve.
(2) Maintain the engine speed at 2,000 ± 2,500 rpm,
and warm up the engine.
(d) Stop the engine, and wait until the engine coolant cools
down.
(e) Refill coolant into the reservoir until it is ºFULLº.
4. CHECK FOR ENGINE COOLANT LEAKS
5. CHECK ENGINE COOLANT SPECIFIC GRAVITY COR-
RECTLY

Make sure your coolant is properly pro-
tected against freezing.
Only use ªToyota Super Long Life Coolantº
or similar high quality ethylene glycol
based non±silicate, non±amine, non±nitrite,
and non±borate coolant with long±life
hybrid organic acid technology. (Coolant
with long±life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See ªChecking the engine coolant levelº
on page 426 in Section 7±2 for details of
coolant type selection.
For the U.S.A.ЪToyota Super Long Life
Coolantº is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about ±35C
(±31F).
For CanadaЪToyota Super Long Life
Coolantº is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about ±42C
(±44F).
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. 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 424 in Section 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 dealerÐthey 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
ªPº and block the front wheels. Do not
use the parking brake, or snow or water
accumulated in and around the parking
brake mechanism may freeze, making it
hard to release.

Change automatic transmission fluid only
as necessary.
Generally, it is necessary to change
automatic transmission fluid only if your
vehicle is driven under one of the Special
Operating Conditions listed in your
ªScheduled Maintenance Guideº or
ªOwner 's Manual Supplementº. When
changing the automatic transmission fluid,
use only ªToyota Genuine ATF WSº (ATF
JWS3324 or NWS9638) to aid in assuring
optimum transmission performance.
Notice: Using automatic transmission
fluid other than ªToyota Genuine ATF
WSº may cause deterioration in shift
quality, locking up of your transmission
accompanied by vibration, and ultimate-
ly damage the automatic transmission
of your vehicle.
Please contact your Toyota dealer for fur-
ther details.
