2011 TOYOTA AYGO engine

IN CASE OF AN EMERGENCY221
If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the engine switch to
“START” with the accelerator pedal fully
depressed. Keep the key and accelerator
pedal in these positions for 15 seconds
and release them. Then try starting the
engine with your foot off the accelerator
pedal.
If the engine does not start after 15 se-
conds of cranking, release the key, wait
a few minutes and try again.
If the engine still will not start, it needs
adjustment or repair. Call any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional, for
assistance.
NOTICE
Do not crank for more than 30 se-
conds at a time. This may overheat
the starter and wiring systems.
(c) Jump starting
To avoid serious personal injury and
damage to your vehicle which might re-
sult from a battery explosion, acid
burns, electrical burns, or damaged
electronic components, these instruc-
tions must be followed precisely.
Vehicles with multi−mode manual transmis-
sion—The engine cannot be started by
push−starting.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent me-
chanic or towing service.
CAUTION
DBatteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses when
jump starting, and avoid spilling
acid on your skin, clothing, or ve-
hicle.
DIf you should accidentally get acid
on yourself or in your eyes, remove
any contaminated clothing and flush
the affected area with water imme-
diately. Then get immediate medical
attention. If possible, continue to
apply water with a sponge or cloth
while en route to the medical office.
DThe gas normally produced by a
battery will explode if a flame or
spark is brought near. Use only
standardized jumper cables and do
not smoke or light a match while
jump starting.
NOTICE
The battery used for boosting must
be12 V. Do not jump start unless you
are sure that the booster battery is
correct.

JUMP STARTING PROCEDURE
1. If the booster battery is installed in
another vehicle, make sure the vehicles
are not touching. Turn the engine
switch to the “LOCK” position.
When boosting, use the battery of
matching or higher quality. Any other
battery may be difficult to jump start
with.
If jump starting is difficult, charge the
battery for several minutes.
2. If the engine in the vehicle with the
booster battery is not running, start it
and let it run for a few minutes. During
jump starting, run the engine at about
2000 rpm with the accelerator pedal
lightly depressed.

224IN CASE OF AN EMERGENCY
If the cause of the battery discharging is
not apparent (for example lights left on)
you should have it checked at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
If the first start attempt is not success-
ful...
Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your en-
gine in the normal way.
If another attempt is not successful, the
battery may be depleted. Have it checked
at any authorized Toyota dealer or repair-
er, or another duly qualified and equipped
professional.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 start” on page 220 in this
Section.
CAUTION
If the engine is not running, the pow-
er assist for the brakes will not work
so braking will be much harder than
usual.

If your engine stalls while
driving

IN CASE OF AN EMERGENCY225
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your Toyota
checked by any authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional, as soon as pos-
sible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, thesystem may not be
recovered until the engine is stopped and
the engine switch is turned to “ACC” or
“LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
If your high engine coolant temperature
warning light flashes to indicates over-
heating, if you experience a loss of
power, or if you hear a loud knocking
or pinging noise, the engine has prob-
ably 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 “N”
(multi−mode manual transmission), or
neutral (manual transmission) 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 engine switch 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 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 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

ing.
MS41002
(a) Towing with wheel lift type truck—
—From rear
(b) Using flat bed truck
—From front
If towing is necessary, we recommend
you have it done by any authorized
Toyota dealer or repairer, or qualified
professional, such as a commercial tow
truck service. In consultation with them,
have your vehicle towed using either (a)
or (b).
Only when you cannot receive a towing
service from any authorized Toyota
dealer or repairer, or qualified profes-
sional, such as a commercial tow truck
service, tow your vehicle carefully in
accordance with the instructions given
in “—Emergency towing” on page 238
in this Section.

If your vehicle becomes
stuckIf your vehicle needs to be
towed—

IN CASE OF AN EMERGENCY237
Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle could be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following pre-
cautions are observed. If necessary, show
this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.
(a) Towing with wheel lift type truck
From front—Release the parking brake.
NOTICE
When lifting wheels, take care to en-
sure adequate ground clearance for
towing at the opposite end of the
raised vehicle. Otherwise, the bumper
and/or underbody of the towed vehicle
may be damaged during towing.
From rear—
DManual transmission:
We recommend using a towing dolly
under the front wheels. If you do not
use a towing dolly, place the engine
switch in the “ACC” position and put
the transmission in neutral.
DMulti−mode manual transmission:
We recommend using a towing dolly.
The towing dolly is set up under the
front wheels. If you do not use the
towing dolly (or if it is not available),
first turn the engine switch “ON” and
shift the shift lever to “N”. Make sure
that the gear is in the “N” position by
checking the gear position indicator.
Multi−mode manual transmission only:
After shifting the shift lever to the “N”
position, always make sure that the gear
is actually disengaged and is in neutral by
pushing the vehicle by hand or other
means. In case the gear can not be put
in neutral, turn the engine switch from the
“OFF” to “ON” position, and operate the
shift lever once from “N” to “E”, “M” or
“R”, then back to “N” again. Then turn the
engine switch from the “ON” to “OFF”
position. These procedures may help put
the gear in neutral. If the gear still can
not be put in neutral, you can not tow
without a towing dolly.
NOTICE
Do not tow with the key removed or
in the “LOCK” position when towing
from the rear without a towing dolly.
The steering lock mechanism is not
strong enough to hold the front
wheels straight.
(b) Using a flat bed truck
