warning TOYOTA AYGO 2011 Service Manual

INFORMATION BEFORE DRIVING YOUR TOYOTA203
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional, as soon as possible to
service the vehicle.
DThe light does not come on when the
engine switch is turned to the “ON”
position or remains on.
DThe light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact any
authorized Toyota dealer or repairer,
or another duly qualified and
equipped professional.
In this case, not only the anti−lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
BRAKE ASSIST SYSTEM
When you slam the brakes on, the
brake assist system judges as an emer-
gency stop and provides more powerful
braking for a driver who cannot hold
down the brake pedal firmly.
When you slam the brakes on, more pow-
erful braking will be applied. At this time,
you may hear a sound in the engine
compartment and feel the vibrations of the
brake pedal. This does not indicate a mal-
function.Vehicles with vehicle stability control sys-
tem—
The brake assist system becomesopera-
tive after the vehicle has accelerated to a
speed in excess of approximately 10 km/h
(6 mph). It stops operating when the ve-
hicle decelerates to a speed below
approximately 5 km/h (3 mph).
For an explanation of thissystem’s warn-
ing light, see “Service reminder indicators
and warning buzzers” on page 127 in Sec-
tion 1−6.

204INFORMATION BEFORE DRIVING YOUR TOYOTA
The electric power steering system, us-
ing an electric motor, assists the turn-
ing of the steering wheel.
In the following cases, you may feel the
steering becomes heavy. However, the
electric power steering system warning
light does not come on. (Because it is
not a malfunction.)
DWhen maneuvering or turning frequently
over a long time
The power steering effect will be re-
duced to prevent the system from over-
heating. Avoid turning the steering
wheel, or stop the vehicle and turn the
engine switch to “ACC” or “LOCK”. The
system will become cool inabout 10
minutes.
NOTICE
Frequent maneuvering and turning
over a long time may cause damage
to the system in which the mecha-
nism prevents overheating of the elec-
tric power steering system.
DWhen racing the engine for 30 seconds
or more with the vehicle stopped
The normal power steering effect will
be obtained when you start driving.
DWhen the battery is discharged
Check the battery’s condition. If
necessary, recharge or replace the
battery. For details, see “Checking
battery condition” on page 278 in
Section 7−3.
INFORMATION
When the steering wheel is turned, a
motor operating sound (whining
sound) may be heard. This occurs
when the power steering motor works
and is not defective.

thorized Toyota dealer or repairer, or
another duly qualified and equipped
professional, as soon as possible to
service the vehicle.
DThe light does not come on when the

INFORMATION BEFORE DRIVING YOUR TOYOTA205
CAUTION
If the electric power steering system
warning light comes on, take your ve-
hicle to any authorized Toyota dealer
or repairer, or another duly qualified
and equipped professional, as soon
as possible. In this case, more effort
is required for the steering wheel to
turn than usual. Drive your vehicle
while firmly gripping the steering
wheel.
Luggage stowage precautions
When stowing cargo and luggage in the
vehicle, observe the following:
DPut cargo and luggage in the luggage
compartment when at all possible. Be
sure all items are secured in place.
DBe careful to keep the vehicle bal-
anced. Locating the weight as far for-
ward as possible helps maintain bal-
ance.
DFor better fuel economy, do not carry
unnecessary weight.
CAUTION
DTo prevent cargo and luggage from
sliding forward during braking, do
not stack anything in the luggage
compartment higher than the seat-
backs. Keep cargo and luggage low,
as close to the floor as possible.
DNever allow anyone to ride in the
luggage compartment. It is not de-
signed for passengers. They should
ride in their seats with their seat
belts properly fastened. Otherwise,
they are much more likely to suffer
death or serious bodily injury, in
the event of sudden braking or a
collision.
DDo not place anything on the lug-
gage cover behind the rear seat-
back. Such items may be thrown
about and possibly injure people in
the vehicle during sudden braking
or an accident.
DDo not drive with objects left on
top of the instrument panel. They
may interfere with the driver’s field
of view. Or they may move during
sharp vehicle acceleration or turn-
ing, and impair the driver ’s control
of the vehicle. In an accident they
may injure the vehicle occupants.

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.

DO−IT−YOURSELF MAINTENANCE: Engine and Chassis275
Replacing wheels
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and inset
∗.
Correct replacement wheels are available
at your Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional.
∗: Conventionally referred to as “offset”.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.
Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
CAUTION
Do not use wheels other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
Aluminum wheel precautions
DWhen installing aluminum wheels,
check that the wheel bolts are tight
after driving your vehicle the first1600
km (1000 miles).
DIf you have rotated, repaired, or
changed your tires, check that the
wheel bolts are still tight after driving
1600 km (1000 miles).
DWhen using tire chains, be careful not
to damage the aluminum wheels.
DToyota recommends the use of Toyota
genuine wheel bolts and wrench de-
signed for your aluminum wheels. Oth-
er bolts and wrenches of matching
quality can also be used.
DWhen balancing your wheels, Toyota
recommends the use of Toyota genuine
balance weights. Other balance weights
canalsobeused.
DAs with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.
