Maintenance and care
AYGO_WE_99E96E
Aluminum wheels (if equipped)
Remove any dirt immediately by using a neutral detergent. Do not use
hard brushes or abrasive cleaners. Do not use strong or harsh chemical
cleaners.
Use the same mild detergent and wax as used on the paint.
Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
Wash detergent from the wheels immediately after use.
To preserve the wheels’ luster, do not allow hot water, such as from
steam cleaning, to contact them directly.
Bumpers
Do not scrub with abrasive cleaners.
CAUTION
When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.

Where to go for service?
In order to maintain your vehicle in the best possible condition, Toyota rec-
ommends that all repairs and service operations be carried out by autho-
rized Toyota dealers or repairers or other duly qualified and equipped
professionals. For repairs and services covered by your warranty, please
visit an authorized Toyota dealer or repairer, who will use genuine Toyota
parts in repairing any difficulties you may encounter. There can also be
advantages in utilizing authorized Toyota dealers or repairers for non-war-
ranty repairs and services, as members of the Toyota network will be able to
expertly assist you with any difficulties you may encounter.
Your Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional will perform all of the scheduled maintenance on your vehicle reli-
ably and economically due to their experience with Toyota vehicles.
Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine misses, stumbling or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon mon-
oxide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
Vehicle pulls to one side when driven straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal
(vehicles with a manual transmission), pedal almost touches the floor,
vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.

AYGO_WE_99E96E
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:
When working on the engine compartment:
Keep hands, clothing and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
ItemsParts and tools
Tire inflation pressure (P. 275)• Tire pressure gauge
• Compressed air source
Washer fluid (P. 269)• Water or washer fluid containing

Maintenance and care
AYGO_WE_99E96E
CAUTION
When working near the electric cooling fan or radiator grille
Be sure the engine switch is off.
With the engine switch on, the electric cooling fan may automatically start to
run if the air conditioning is on and/or the coolant temperature is high.
(P. 266)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also, a backfire could cause a fire in the engine com-
partment.
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

256 4-3. Do-it-yourself maintenance
AYGO_WE_99E96E
CAUTION
Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
After installing the support rod into the slot
Make sure the rod supports the hood securely from falling down on to your
head or body.
When detaching the support rod from the clip
Take care to prevent hands or arms from being hit against the inside of the
engine hood. Failure to do so may result in serious injury.
Hold the support protector area to prevent scalding.
NOTICE
When closing the hood
Be sure to return the support rod to its clip before closing the hood. Closing
the hood with the support rod up could cause the hood to bend.

258 4-3. Do-it-yourself maintenance
AYGO_WE_99E96E
CAUTION
When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
When using a floor jack, follow the instructions of the manual provided with
the jack.
Do not use the jack that was supplied with your vehicle.
Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
Do not start the engine while the vehicle is supported by the floor jack.
Stop the vehicle on level, firm ground, firmly set the parking brake and shift
the shift lever to E, M or R (vehicles with a multi-mode manual transmis-
sion) or R (vehicles with a manual transmission).
Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.
Do not jack the vehicle at the front
under cover and the rear suspension.
The front under cover and the rear sus-
pension may be damaged.Front under
