2007 TOYOTA YARIS engine overheat

2182007 YARIS HATCHBACK from Feb. ’07Prod. (OM52754U)
Because 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, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to “If
your vehicle overheats” on page 227 in
Section 4
Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in “P” (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 “P” (automatic) and turn off the engine. When restarting out after parking on a
slope:
1. With the transmission in “P” position (automatic) or the clutch pedal de-
pressed (manual), start the engine.
(With an automatic transmission, be
sure to keep the brake pedal de-
pressed.)
2. Shift into gear.
3. Release the parking brake (also foot brake on automatic transmission ve-
hicles) and slowly pull or back away
from the wheel blo cks. Stop and apply
your brakes.
4. Have someone retrieve the blo cks.
CAUTION
Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because insta-
bility (swaying) of a towing vehicle
trailer combination usually in-
creases as the speed increases, ex-
ceeding 72 km/h (45 mph) may
cause loss of control.
Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.
Avoid 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:
Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See Section
7 −2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Avoid lengthy warmup 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.
Put the selector lever into the “D”
when engine braking is not required.
Driving with the selector lever in “3”
will reduce the fuel economy (For de-
tails, see “Automatic transmission” on
page 125 in Section 1 −7.)
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
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 lugging or overrev-
ving. 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 needless
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 tunedup and in
top shape. A dirty air cleaner,
improper valve clearance, dirty plugs,
dirty oil and grease,brakes not
adjusted, etc. all lower engine
performance and contribute 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
information, please refer to the
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.)

Before making these checks, make sure
you have followed the correct starting pro-
cedure given in “How to start the engine”
in Section 3 and that you have sufficient
fuel. If your vehicle is equipped with the
engine immobilizer system, also check
whether the other keys will start the en-
gine. If they work, your key may be bro-
ken. Have the key checked at your Toyota
dealer. If none of your keys work, there
may be a malfunction in the immobilizer
system. Call your Toyota dealer. (See
“Keys (with engine immobilizer system)”
on page 11 in Section 1 −2.)
If the engine does not turn over or
turns over too slowly— 1. Check that the battery terminals are tight and clean.
2. If the battery terminals are connected correctly, switch on the interior light.
3. If the light does not come on, is dim or goes out when the starter is
cranked, the battery is discharged. You
may try jump starting. See “(c) Jump
starting” for further instructions.
If the light comes on and is normal, but
the engine still will not start, it needs
adjustment or repair. Call a Toyota dealer
or qualified repair shop.NOTICE
Do not pull or pushstart the ve-
hicle. It may damage the vehicle or
cause a collision when the engine
starts. Also the threeway catalytic
converter may overheat and become a
fire hazard.
If the engine turns over at its normal
speed but will not start— 1. Turn the ignition key to “ACC” or “LOCK” and try starting the engine
again.
2. If the engine will not start, the engine may be flooded because of repeated
cranking. See “(b) Starting a flooded
engine” for further instructions.
3. If the engine still will not start, it needs adjustment or repair. Call a Toyota
dealer or qualified repair shop.
(b) Starting a flooded engine
If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the ignition key to
“START” with the accelerator pedal fully
depressed, and hold the key at this posi-
tion for about 30 seconds. Then the
cranking hold function stops cranking au-
tomatically, and you can try starting the
engine with your foot off the accelerator
pedal.
If the engine does not start, wait a few
minutes and try again.
If the engine still will not start, it needs
adjustment or repair. Call a Toyota dealer
or qualified repair shop for assistance.

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 “P”
(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 and make sure the electric
cooling fan is operating. If it is not,
turn the ignition off.
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.
3. Look for obvious coolant leaks from theradiator, 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 coolant is leaking, stop the en-gine immediately. Call a Toyota dealer
for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
For the coolant type see “Coolant type
selection” on page 272 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.
6. 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. Seri-
ous coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Toyota dealer.
