coolant TOYOTA AYGO 2011 User Guide

226IN CASE OF AN EMERGENCY
4. If the coolant is leaking, stop the en-
gine immediately. Call any authorized
Toyota dealer or repairer, or another
duly qualified and equipped profession-
al, for assistance.
5. If there are no obvious leaks, 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 267 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
necessary, 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.1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from
the traffic. Avoid stopping on the center
divider of a highway. Park on a level
spot with firm ground.
2. Stop the engine and turn on your
emergency flashers.
3.Manual transmission:
Firmly set the parking brake and put
the transmission in reverse.
Multi−mode manual transmission:
Securely apply the parking brake and
turn the engine switch “ON”. After the
operation, shift the shift lever to “M(1)”,
“E(1)” or “R”.
4. Have everyone get out of the vehicle
onthesideawayfromtraffic.
5. Read the following instructions thor-
oughly.
CAUTION
When jacking, be sure to observe the
following to help reduce the possibil-
ity of death or serious injury:
DFollow jacking instructions.
DDo not put any part of your body
under a vehicle supported by a
jack. Otherwise, death or serious
injury may occur.
DDo not start or run the engine while
your vehicle is supported by the
jack.
DStop the vehicle on a level firm
ground, firmly set the parking brake

MAINTENANCE REQUIREMENTS255
Note, however, that some maintenance
tasks require special tools and skills.
These are best performed by qualified
technicians. Even if you’re an experienced
do−it−yourself mechanic, we recommend
that repairs and maintenance be
conducted by an authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional. Any authorized
Toyota dealer or repairer will keep a
record of maintenance, which could be
useful should you ever require Warranty
Service. Should you choose to select a
qualified and equipped professional other
than an authorized Toyota repairer to
service or maintain your vehicle, we
recommend that you request that a record
of maintenance be kept.
The service interval for scheduled main-
tenance is determined by the odometer
reading or time interval, whichever
comes first, shown in the schedule.
Rubber hoses (for cooling and heater
system, brake system and fuel system)
should be inspected by a qualified tech-
nician in accordance with the Toyota
maintenance schedule.
They are particularly important mainte-
nance items. Have any deteriorated or
damaged hoses replaced immediately.
Note that rubber hoses will deteriorate
with age, resulting in swelling, chafing or
cracks.Be on the alert for changes in perfor-
mance, sounds, and visual tip−offs that
indicate service is needed. Some impor-
tant clues are as follows:
DEngine missing, stumbling, or pinging
DAppreciable loss of power
DStrange engine noises
DA leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
DChange in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaustsystem checked im-
mediately.)
DFlat−looking tire; excessive tire squeal
when cornering; uneven tire wear
DVehicle pulls to one side when driving
straight on a level road
DStrange noises related to suspension
movement
DLoss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
DEngine coolant temperature continually
higher than normal
If you notice any of these cues, take your
vehicle to any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional, as soon as pos-
sible. It probably needs adjustment or re-
pair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.

260DO−IT−YOURSELF MAINTENANCE: Introduction
If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this Section.
You should be aware that improper or in-
complete servicing may result in operating
problems.
This Section gives instructions only for
those items that are relatively easy for an
owner to perform. As explained in Section
6, there are still a number of items that
must be done by a qualified technician
with special tools.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:
CAUTION
DWhen the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
DRight after driving, the engine
compartment—the engine, radiator,
exhaust manifold, and spark plug
boots, etc. —will be hot. So be
careful not to touch them. Oil,
fluids and spark plugs may also be
hot.
DIf the engine is hot, do not remove
the radiator cap or coolant reser-
voir cap or loosen the drain plugs,
to prevent burning yourself.
DDo not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
DDo not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
DBe extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
DDo not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
DBe sure that the engine is off if you
work near the electric cooling fan
or radiator grille. With the engine
on, the electric cooling fan will au-
tomatically start to run if the en-
gine coolant temperature is high
and/or the air conditioning is on.
DUse eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
DUsed engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
DDo not leave used oil within the
reach of children.
DDispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
DTake care when filling the brake
fluid reservoir because brake fluid
can harm your hands or eyes. If
fluid gets on your hands or in your
eyes, flush the affected area with
clean water immediately. If you still
feel uncomfortable with your hands
or eyes, go to the doctor.

precautions

DO−IT−YOURSELF MAINTENANCE: Introduction261
NOTICE
zRemember that battery and ignition
cables carry high currents or volt-
ages. Be careful not to accidentally
cause a short circuit.
zAdd only “Toyota Super Long Life
Coolant” or similar high quality eth-
ylene glycol based non−silicate,
non−amine, non−nitrite, and non−bo-
rate coolant with long−life hybrid
organic acid technology to fill the
radiator. “Toyota Super Long Life
Coolant” is a mixture of 50% cool-
ant and 50% deionized water.
zIf you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging any parts
or paint.
zDo not allow dirt or anything else
to fall through the spark plug holes.
zDo not pry the outer electrode of a
spark plug against the center elec-
trode.
zUse only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
zIf you spill brake fluid, be sure to
wash it off with water to prevent it
from damaging any parts or paint.
zDo not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
zBe careful not to scratch the glass
surfaces with the wiper frames.
zWhen closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.

Look at the see−through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the “F” and “L” lines on the reservoir.
If the level is low, add coolant. (For the
coolant type, see “Coolant type selec-
tion” described below.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the “L” line, add
coolant. Bring the level up to the “F” line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, engine coolant filler cap,
radiator cap and drain cock and water
pump.
If you can find no leak, have any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional,
test the cap pressure and check for leaks
in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Use of improper coolants may damage
your engine coolingsystem.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life hy-
brid organic acid technology. (Coolant with
long−life hybrid organic acid technology is
a combination of low phosphates and or-
ganic acids.)
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about−35_C(−31_F).
