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 380 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
Pº 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.
Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may
cause serious damage to your vehicle.

Front
Rear
The power outlets (12 VDC) are de-
signed for power supply for car acces-
sories.
The key must be in the ACCº or ONº
position for the power outlets to be used.
NOTICE

To prevent the fuse from being
blown, do not use the electricity
over the total vehicle capacity of
12VDC/120W (front and rear outlets
together).

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

Close the power outlet lids when
the power outlets are not in use.
Inserting a foreign object other than
the appropriate plug that fits the
outlet, or allowing any liquid into
the outlet may cause electrical fail-
ure or short circuits.

This power outlet (115 VAC) is designed
for use as a power supply for electric
appliances in the vehicle.
The key must be in the ONº position for
the power outlet to be used.
The maximum capacity for this power out-
let is 115 VAC/100W. If you attempt to
use an appliance that requires more than
115 VAC or 100W, the protection circuit
will activate and cut the power supply.
The power supply will restart automatically
when you use an appliance that operates
within the 115 VAC/100W limits.Main switch
To use the power outlet, push the main
switch on the instrument panel.
An indicator light will illuminate to indicate
that the power outlet is ready for use.
Push the main switch once again to turn
the power outlet off. When the power out-
let is not in use, make sure that the main
switch is turned off.
NOTICE

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

Close the power outlet lid when the
power outlet is not in use. Inserting
anything other than an appropriate
plug that fits the outlet may cause
electrical failure or short circuits.
The power outlet is not designed for
the following electric appliances even
though their power consumption is un-
der 115 VAC/100W. These appliances
may not operate properly.

DTC P0037 OXYGEN SENSOR HEATER CONTROL
CIRCUIT LOW (BANK 1 SENSOR 2)
DTC P0038 OXYGEN SENSOR HEATER CONTROL
CIRCUIT HIGH (BANK 1 SENSOR 2)
CIRCUIT DESCRIPTION
Refer to DTC P0136 on page 05-1 18.
HINT:
The ECM provides a pulse width a modulated control circuit to adjust current through the heater. The oxygen
sensor heater circuit uses a relay on the +B side of the circuit.
DTC No.DTC Detection ConditionTrouble Area
P0037
Heater current of less than 0.3 A when the heater operates
with +B greater than 10.5 V
(1 trip detection logic)
Open or short in heater circuit of heated oxygen sensor

Heated oxygen sensor heater

EFI relay

ECM
P0038Heater current exceeds 2 A when heater operates
(1 trip detection logic)
Same as DTC No. P0037
HINT:
Sensor 2 is the sensor farthest away from the engine assembly.
MONITOR DESCRIPTION
The sensing portion of the heated oxygen sensor has a zirconia element that is used to detect oxygen con-
centration in the exhaust. If the zirconia element is at the proper temperature and the difference of the oxy-
gen concentration between the inside and outside surface of the sensor is large, the zirconia element will
generate 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 sen-
sor. 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 A when the heater is OFF.
Similarly, the ECM will set a low current DTC if the current is less than 0.25 A when the heater is ON.
