overheating TOYOTA 4RUNNER 2000 Owners Manual

1852000 4Runner (OM35762U)
NOTICE

Do not crank for more than 30 se-
conds at a time. This may overheat
the starter and wiring systems.

Do not race a cold engine.

If the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.

Always slow down in gusty crosswinds.
This will allow you much better control.

Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp- edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.

When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in Pº (automatic) or in first or
reverse (manual). If necessary, block
the wheels.

Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.

Four- wheel drive modelsÐToyota rec-
ommends not using four- wheel drive on
dry hard- surfaced roads, because four-
wheel driving will cause unnecessary
noise and wear, and poor fuel econo-
my.

Four- wheel drive modelsÐIn cold tem-
peratures, noise may occur when driv-
ing in two- wheel drive before the trans-
fer is warmed up. Therefore, first drive
in four- wheel drive until the transfer is
warmed up.
CAUTION

Before driving off, make sure that
the parking brake is fully released
and the parking brake reminder
light is off.

Do not leave your vehicle unat-
tended while the engine is running.

Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.

Because stopping distance may be in-
creased, vehicle- to- vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of
speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as
you may skid, resulting in jackknifing
and loss of control. This is especially
true on wet or slippery surfaces.

Avoid jerky starts or sudden accelera-
tion. If your vehicle has a manual
transmission, prevent excessive clutch
slippage by keeping engine rpm low
and not racing the engine. Always start
out in first gear.

Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.

Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this by
making a larger than normal turning
radius with your vehicle.

Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. Steer
straight ahead. If you make no extreme
correction with the steering or brakes,
the vehicle and trailer will stabilize.

Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room befo-
re changing lanes.

In order to maintain engine braking effi-
ciency, do not use fifth gear (manual
transmission) or overdrive (automatic
transmission).

Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over
30C [85F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to If
your vehicle overheatsº in Section 4 of
this manual.

Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in Pº (automatic)
or in first or reverse (manual). Avoid
parking on a slope with a trailer, but
if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release your brakes slowly until the
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into first or reverse (manual) or
Pº (automatic) and turn off the engine.

Avoid long engine idling. If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.

Avoid engine lug or overrevving. Use
a gear position suitable for the road on
which you are travelling.

Avoid continuous speeding up and
slowing down. Stop- and- go driving
wastes fuel.

Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.

Avoid heavy traffic or traffic jams
whenever possible.

Do not rest your foot on the clutch
or brake pedal. This causes premature
wear, overheating and poor fuel econo-
my.

Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.

Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.

Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.

Keep your vehicle tuned- up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease,brakes not adjusted, etc. all
lower engine performance and contrib-
ute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance informa-
tion, please refer to the separate
Scheduled Maintenance Guideº or
Owner 's Manual Supplementº).
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is run-
ning.

Do not connect it to or near any part
that moves when the engine is
cranked.
CAUTION
When making the connections, to
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm
for several minutes with the accelerator
pedal lightly depressed.
6. Carefully disconnect the cables in the
exact reverse order: the negative cable
and then the positive cable.
7. Carefully dispose of the battery cover
clothsÐthey may now contain sulfuric
acid.
8. If removed, replace all the battery vent
plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on),
you should have it checked.If your engine stalls while driving...
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see If your
vehicle will not startº.
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.
If your vehicle overheats
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve-
hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) and ap-
ply the parking brake. Turn off the air
conditioning if it is being used.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.

Shift into the Lº position. The trans-
mission will downshift to the first gear
When the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be en-
abled.
3RZ- FE engine
54 km/h (33 mph)
5VZ- FE engine
58 km/h (36 mph)
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 is not applied because the cruise
control is not cancelled.
For ways to decrease the vehicle speed,
see Cruise controlº in this section.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(e) Using 2º and Lº positions
The 2º and Lº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in 2º or Lº, you
can start the vehicle in motion as with the
lever in Dº.
With the selector lever in 2º, the vehicle
will start in the first gear and automatical-
ly shift to second gear.
With the selector lever in Lº, the trans-
mission is engaged in first gear.
NOTICE

Be careful not to overrev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:
2º 120 km/h (74 mph). . . . . . . . . . . .
Lº 65 km/h (40 mph). . . . . . . . . . . .

Do not continue hill climbing or
hard towing for a long time in the
2º or Lº position. This may cause
severe automatic transmission dam-
age from overheating. To prevent
such damage, Dº position should
be used in hill climbing or hard
towing.
(f) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with
your foot, shift the selector lever to the
Rº position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(g) Parking
1. Bring the vehicle to a complete stop.
2. Pull the parking brake lever up fully to
securely apply the parking brake.

tion.
CAUTION
Never attempt to move the selector
lever into Pº position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
(h) Good driving practice
If the transmission repeatedly shifts up
and down between third gear and over-
drive when climbing a gentle slope, the
overdrive should be turned off. Be sure
to turn the switch on immediately after-
ward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Do not hold the vehicle on an up-
grade with the accelerator pedal. It
can cause the transmission to over-
heat. Always use the brake pedal or
parking brake.
