Sensor 2 refers to the sensor farther away from the engine assembly.
MONITOR DESCRIPTION
The sensing portion of the heated oxygen sensor has a zirconia element which is used to detect oxygen
concentration in the exhaust. If the zirconia element is at the proper temperature and difference of the oxy-
gen concentration between the inside and outside surface of sensor is large, the zirconia element will gener-
ate voltage signals. In order to increase the oxygen concentration detecting capacity in the zirconia element,
the ECM supplements the heat from the exhaust with heat from a heating element inside the sensor. When
current in the sensor is out of the standard operating range, the ECM interprets this as a fault in the heated
oxygen sensor and sets a DTC.
Example:
The ECM will set a high current DTC if the current in the sensor is more than 2.0 A when the heater is OFF.
Similarly, the ECM will set a low current DTC if the current is less than 0.3 A when the heater is ON.

2. CHECK BATTERY CAPACITY
HINT:

Make sure to use the TOYOTA electrical tester.

With the battery unloaded, judge can not be made wheth-
er the battery is available or not on the test.

When the transmitter is faulty, the energy amount left in
the battery might not be checked correctly.

On the lithium battery used for the transmitter, the voltage
more than 2.5 V with the battery unloaded is shown on the
tester until the energy is completely consumed.
Accordingly when inspecting the energy amount left in the
battery, it is necessary to measure the voltage when the
battery is loaded (1.2 kW).
(a) Remove the cover using a (±) driver.
(b) Remove the battery (lithium battery) from the transmitter.
(c) Connect the lead to the (±) terminal of the transmitter and
install the battery.
(d) Connect the (+) tester to the (+) battery (lithium battery),
and (±) tester to the lead respectively.
(e) Press one of the transmitting switches on the transmitter
for approx. 1 second.
(f) Press the transmitting switch on the transmitter again to
check the voltage.
Standard: 2.1 V or more

CIGARETTE LIGHTER
To use the cigarette lighter, press it in.
After it finishes heating up, it automati-
cally pops out ready for use.
Do not hold the cigarette lighter pressed
in.
Use a Toyota genuine cigarette lighter or
equivalent for replacement.
ASHTRAYS
Front: To use the ashtray, pull it out.
Rear: To use the ashtray, raise the lid.
When finished with your cigarette, thor-
oughly extinguish it in the ashtray to pre-
vent other cigarette butts from catching
fire. After using the ashtray, push it back
in completely.
FrontÐTo remove the ashtray, press down
on the lock spring plate and pull out.
RearÐTo remove the ashtray, pull it out.
CAUTION
To reduce the chance of injury in
case of an accident or sudden stop
while driving, always completely close
the ashtray after use.

NOTICE

To prevent the fuse from being
blown, do not use the electricity
over the total vehicle capacity of
12V/120W.

To prevent the battery from being
discharged, do not use the power
outlets longer than necessary when
the engine is not running.

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.
