2000 TOYOTA 4RUNNER coolant temperature

892000 4Runner (OM35762U)

Idling for a long period with the air
conditioning on in stop- and- go traffic.

Towing a trailer.
NOTICE

Do not remove the thermostat in
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.

Do not continue driving with an
overheated engine. See If your ve-
hicle overheatsº in Section 4.
Tachometer
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
Odometer and two trip meters
This meter displays the odometer and
two trip meters.
1. OdometerÐShows the total distance
the vehicle has been driven.
2. Two trip metersÐShow two different
distances independently driven since
the last time each trip meter was set
to zero.
You can use one trip meter to calculate
the fuel economy and the other to
measure the distance on each trip. All
trip meter data is cancelled if the elec-
trical power source is disconnected.
3. Trip meter reset knobÐResets the two
trip meters to zero, and also change
the meter display.

(b) Overdrive switch
You can select either a third gear (with
overdrive off) or fourth gear (with over-
drive on) by pushing this switch.
To turn the overdrive off, push the switch.
The O/D OFFº indicator light should come
on. To turn the overdrive on again, push
the switch again. The O/D OFFº indicator
light should go off.
Always drive your vehicle with the over-
drive on for better fuel economy and
quieter driving.
If the engine is turned off when the over-
drive is off and restarted, the overdrive
will be on automatically.Vehicles with cruise controlÐWhen the
cruise control is being used, even if you
downshift the transmission by pushing and
releasing the overdrive switch, engine
braking will not be applied because the
cruise control is not cancelled.
For ways to decrease the vehicle speed,
see Cruise controlº in this section.
(c) Normal driving
1. Start the engine as instructed in How
to start the engineº in Section 3. The
transmission must be in Pº or Nº.
2. With your foot holding down the brake
pedal, shift the selector lever to Dº.
When the lever is in the Dº position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc.
Always turn the overdrive on for better
fuel economy and quieter driving. If the
engine coolant temperature is low, the
transmission will not shift into the over-
drive gear even with the overdrive on.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
(d) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Push the overdrive switch. The O/D
OFFº indicator light will come on and
the transmission will downshift to the
third gear.
Shift into the 2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the following
speed, and stronger engine braking will
be enabled.

(c) Normal driving
1. Start the engine as instructed in How
to start the engineº in Section 3. The
transmission must be in Pº or Nº.
When the front drive control lever is in
L4º (low- speed position, four- wheel
drive), the driving pattern selector setting
has no effect on gear shift timing. (See
Four- wheel drive systemº in this section
for information of the front drive control
lever.)
2. With your foot holding down the brake
pedal, shift the selector lever to Dº.
When the lever is in the Dº position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc.Always turn the overdrive on for better
fuel economy and quieter driving. If the
engine coolant temperature is low or when
the front drive control lever is in L4º
(low- speed position, four- wheel drive), the
transmission will not shift into
the overdrive gear even with the overdrive
on. (See Four- wheel drive systemº in this
section for information of the front drive
control lever.)

tor pedal while shifting.

(d) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Push the overdrive switch. The O/D
OFFº indicator light will come on and
the transmission will downshift to the
third gear.

API service symbol
ILSAC certification mark
Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SJ. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W- 30. Energy-
Conservingº shown in the lower portion,
indicates that the oil has fuel- saving ca-
pabilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.Look at the see- through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the Fº and Lº lines on the reservoir.
If the level is low, add ethylene- glycol
type coolant for a proper corrosion
protection of aluminum components.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the Lº line, add
coolant. Bring the level up to the Fº line.
Always use ethylene- glycol type coolant
for a proper corrosion protection of alumi-
num components. See information in the
next column.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
