1998 TOYOTA 4RUNNER engine

4RUNNER (1998)
The gauge indicates the engine
coolant temperature when the igni-
tion switch is on. The engine oper-
ating temperature will vary with
changes in weather and engine
load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow
the engine to cool.
Your vehicle may overheat during se-
vere operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after
high speed driving.
Idling for a long period with the air
conditioning on in stop- and- go traf-fic.
Towing a trailer
NOTICE
Do not remove the thermostat
in the engine cooling system asthis may cause the engine to
overheat. The thermostat is de-
signed to control the flow ofcoolant to keep the temperatureof the engine within the speci-
fied operating range.
Do not continue driving with anoverheated engine. See ºIf your
vehicle overheatsº in Part 4.
Tachometer

4RUNNER (1998)
The tachometer indicates engine
speed in thousands of rpm (revolu-
tions per minute). Use it while driv-
ing to select correct shift points
and to prevent engine 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 causesevere engine damage.

(a) Brake System Warning Light
This light has the following functions:
Parking brake reminder
If this light is on, make sure the park-
ing brake is fully released. The light
should go off.
Low brake fluid level warning
If this light comes on and stays on
while you are driving, slow down and
pull off the road. Then stop the ve-
hicle carefully. There may be a prob-
lem somewhere in the brake system.
Check the fluid level of the see-
through reservoir.
To make sure the parking brake has
not caused the warning light to come
on, check to see that the parking
brake is fully released.
If the brake fluid level is low...
At a safe place, test your brakes by
starting and stopping.
If you judge that the brakes still
work adequately, drive cautiously to
your nearest dealer or shop for re-
pairs.
If the brakes are not working, have
the vehicle towed in for repairs.
(For towing information, see Part
4.)CAUTION
It is dangerous to continue driv-
ing normally when the brake fluid
level is low.
If the brake fluid level is correct...
Have the warning system checked by
your Toyota dealer.
(b) Seat Belt Reminder Light and
Buzzer
Once the ignition key is turned to
ºONº or ºSTARTº, the reminder light
and buzzer come on if the driver's
seat belt is not fastened. Unless the
driver fastens the belt, the light keeps
on flickering and the buzzer sounds
for about 4 to 8 seconds.
(c) Discharge Warning Light
This light warns that the battery is
being discharged.
If it comes on while you are driving,
there is a problem somewhere in the
charging system.
The engine ignition will continue to
operate, however, until the battery is
discharged. Turn off the air condition-
ing, blower, radio, etc., and drive di-
rectly to the nearest Toyota dealer or
repair shop.
NOTICE
Do not continue driving if the en- gine drive belt is broken or loose.
(d) Low Oil Pressure Warning Light
This light warns that the engine oil
pressure 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 immediate-
ly. 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 ac-
celerated slightly.
The light may come on when the oil
level is extremely low. It is not de-
signed to indicate low oil level, and
the oil level must be checked using
the level dipstick.
NOTICE
Do not drive the vehicle with thewarning light onÐeven for oneblock. It may ruin the engine.

(e) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See ºFuel gaugeº in Chapter
1- 5 for instructions.)
b. The fuel tank cap is not tightened
securely. (See ºFuel tank capº in
Chapter 1- 2 for instructions.)
c. There is a problem somewhere in
your engine or automatic transmis-
sion electrical system.
If it comes on while you are driving
in case c, have your vehicle checked/
repaired by your Toyota dealer as
soon as possible.
(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
movement of fuel in the tank, the low
fuel level warning light may come on
earlier than usual.
(g) ºABSº Warning Light
This light warns that there is a prob-
lem somewhere in your anti- lock
brake system. If the light comes on while you are
driving, have your vehicle checked by
your Toyota dealer as soon as pos-
sible.
The light will come on when the igni-
tion key is turned to the ºONº posi-
tion. After about 3 seconds, the light
will go off.
When the ºABSº warning light is on
(and the brake system warning light is
off), the brake system operates con-
ventionally but anti- lock brake system
is not assisting brake performance so
that the wheels can lock- up during
sudden braking or braking on slippery
road surfaces.
Vehicles with rear differential lock sys-
temÐ
The anti-lock brake system does not
operate when the rear differential is
locked. It is normal operation for the
ºABSº warning light to be on at this
time.

ignition key is turned to the ºACCº
or ºONº position. After about 6 se-
conds, the light will go off. This
means the airbag system is operat-
ing properly.
The warning light system monitors the
airbag sensor assembly, inflators,
warning light, interconnecting wiring
and power sources.
If either of the following conditions
occurs, this indicates a malfunction
somewhere in the parts monitored by
the warning light system. Contact 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
ºACCº or ºONº position or remains on.

Two- wheel drive models

4RUNNER (1998)
Your automatic transmission has a
shift lock system to minimize the pos-
sibility of incorrect operation. This
means you can only shift out of ºPº
position when the brake pedal is de-
pressed (with the ignition switch in
ºONº position and the lock release
button depressed).
(a) Normal driving 1. Start the engine as instructed in ºHow to start the engineº in Part 3.
The transmission must be in ºPº or
ºNº.
2. With your foot holding down the brake pedal, shift the selector lever
to ºDº.
In ºDº position, the automatic trans-
mission system will select the most
suitable gear for running conditions
such as normal cruising, hill climbing,
hard towing, etc.
Always turn the overdrive switch on
for better fuel economy and quieter
driving. If the engine coolant tempera-
ture is low, the transmission will not
shift into the overdrive gear even with
the overdrive switch on.
CAUTION
Never put your foot on the accel-
erator pedal while shifting.
3. Release the parking brake and brake pedal. Depress the accelera-
tor pedal slowly for smooth start-
ing.
(b) Using engine braking
To use engine braking, you can down-
shift the transmission as follows: Turn off the overdrive switch. The
ºO/D OFFº indicator light will come
on and the transmission will down-
shift to the third gear.
Shift into the º2º position. The
transmission will downshift to the
second gear when the vehicle
speed drops down to or lower than
the following speed, and more pow-
erful engine braking will be ob-
tained.
3RZ- FE engine.....112 km/h (69
mph)
5VZ- FE engine.....119 km/h (73
mph)
Shift into the ºLº position. The
transmission will downshift to the
first gear When the vehicle speed
drops down to or lower than the
following speed, and maximum en-
gine braking will be applied.
