2012 TOYOTA DYNA 100/150 overheating

STARTING AND DRIVING135
Instruments and controls.Especially
make sure the service reminder indicators,
instrument lights, and defroster are work-
ing.
Brakes.Make sure the pedal has enough
clearance.
Spare fuses.Make sure you have spare
fuses. They should cover all the amperage
ratings designated on the fuse box lid.
In the engine compartment
Coolant level.Make sure the coolant lev-
el is correct. (See page 198 in Section
7−2 for instructions.)
Wiring.Look for damaged, loose, or dis-
connected wires.
Fuel lines.Check the lines for leaks or
loose connections.
AFTER STARTING THE ENGINE
Exhaust system.If you notice any
change in the sound of the exhaust or
smell exhaust fumes, have the cause lo-
cated and corrected immediately. (See
“Engine exhaust cautions” on page 122 in
Section 2.)
Engine oil level.Stop the engine and
check the dipstick with the vehicle parked
on a level spot. (See page 196 in Section
7−2 for instructions.)
WHILE DRIVING
Instruments.Make sure the speedometer
and gauges are working.
Brakes.In a safe place, check that the
brakes do not pull to one side when ap-
plied.
Anything unusual?Look for loose parts
and leaks. Listen for abnormal noises.
If everything looks O.K., set your mind at
ease and enjoy your trip!DAlways slow down in gusty crosswinds.
This will allow you much better control.
DDrive 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 such
as a tire burst.
Drive slowly when passing over bumps
or travelling on abumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
DWhen 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 first or reverse. If necessary,
block the wheels.
DWashing 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 any authorized Toyota dealer
or repairer, or another duly qualified
and equipped professional, for assis-
tance.
CAUTION
DBefore driving off, make sure the
parking brake is fully released and
the parking brake reminder light is
off.
DDo not leave your vehicle unat-
tended while the engine is running.
DDo not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.

Tips for driving in various
conditions

STARTING AND DRIVING145
DBacking with a trailer is difficult and
requires practice. Grip the bottom of
the steering wheel and move your hand
to the left to move the trailer to the
left. Move your hand to the right to
move the trailer to the right. (This pro-
cedure is generally opposite to that
when backing without a trailer.) Also,
just turn the steering wheel a little at
a time, avoiding sharp or prolonged
turning. Have someone guide you when
backing to reduce the risk of an acci-
dent.
DRemember 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.
DCrosswinds 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. If it is
necessary to reduce speed, brake
slowly. Steer straight ahead. If you
make no extreme correction with the
steering or brakes, the vehicle and
trailer will stabilize.
DBe 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 be-
fore changing lanes.
DTo maintain engine braking efficiency,
when using engine braking, do not use
fifth gear.
DBecause of the added load of the trail-
er, your vehicle’s engine may overheat
on hot days (at temperatures over
30_C[85_F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, pull off the road and stop
in a safe spot. Refer to “If your vehicle
overheats” on page 156 in Section 4.
DAlways place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in first or reverse.
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 and turn off
the engine.
When restarting out after parking on a
slope:
1. With the clutch pedal depressed, start
the engine.
2. Shift into gear.
3. Release the parking brake and slowly
pull or back away from the wheel
blocks. Stop andapply your brakes.
4. Have someone retrieve the blocks.

146STARTING AND DRIVING
CAUTION
DObserve the legal maximum speeds
for trailer towing.
DSlow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts while descending steep or
long downhill grades.
DAvoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.
Improving fuel economy is easy—just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
DKeep your tires inflated at the cor-
rect pressure.Underinflation causes
tire wear and wastes fuel. See page
201 in Section 7−2 for instructions.
DDo not carry unneeded weight in
your vehicle.Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
DAvoid lengthy warm−up idling.Once
the engine is running smoothly, begin
driving—but gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
DAccelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
DAvoid 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.
DAvoid engine lugging or over−rev-
ving.Use a gear position suitable for
the road on which you are travelling.
DAvoid continuous speeding up and
slowing down.Stop−and−go driving
wastes fuel.
DAvoid 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.
DAvoid heavy traffic or traffic jams
whenever possible.
DDo not rest your foot on the clutch
or brake pedal.This causes premature
wear, overheating and poor fuel econo-
my.

How to save fuel and make
your vehicle last longer

156IN CASE OF AN EMERGENCY
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 neu-
tral and apply 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 engine access hole cover
or tilting the cab. If there is no coolant
or steam boiling over, leave the engine
running and make sure the electric
cooling fan is operating. If it is not,
turn the engine switch off.
CAUTION
To help avoid serious injury, keep the
engine access hole cover closed or
the cab lowered until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Visually check to see if the engine
drive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or the
coolant is leaking, stop the engine im-
mediately. Call any authorized Toyota
dealer or repairer, or another duly qual-
ified and equipped professional, for as-
sistance.
5. If the engine drive belt is O.K. and
there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry,
add coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type, see “Coolant type
selection” on page 199 in Section 7−2.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
