WARNING
■When the vehicle is stopped
● Do not race the engine.
If the vehicle is in any gear other than N, the vehicle may accelerate sud-
denly and unexpectedly, causing an accident.
● On vehicles with a multi-mode manual transmission, in order to prevent
accidents due to the vehicle rolling away, always keep depressing the
brake pedal while the engine is running, and apply the parking brake as
necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.
■ When the vehicle is parked
● Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
● Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.
● Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.

WARNING
●On vehicles with a multi-mode manual transmission, always apply the
parking brake, shift the shift lever to E, M or R, stop the engine and lock
the vehicle.
Do not leave the vehicle unattended while the engine is running.
● Do not touch the exhaust pipes while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
● On vehicles with a multi-mode manual transmission, do not turn off the
engine until 1st or reverse is engaged properly and completely. Confirm
that the gear is engaged by viewing the gear position indicator.
Parking the vehicle without a gear engaged may cause the vehicle to
move result in an accident.
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the brake booster device does not operate, do not follow other vehicles
closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase.
Have your brakes fixed immediately.

Cargo and luggage
Take notice of the following information about storage precau-
tions, cargo capacity and load.
WARNING
■ Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment:
● Receptacles containing gasoline
● Aerosol cans
■ Storage precautions
Observe the following precautions.
Failure to do so may prevent t he pedals from being depressed properly,
may block the driver’s vision, or may re sult in items hitting the driver or pas-
sengers, possibly causing an accident.
● Stow cargo and luggage in the luggage compartment whenever possible.
● Do not stack anything in the luggage compartment higher than the seat-
backs.
● Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the luggage cover (if equipped)
• On the instrument panel
• On the dashboard
● Secure all items in the occupant compartment.
● When you fold down the rear seats, long items should not be placed
directly behind the front seats.
● Never allow anyone to ride in the luggage compartment. It is not designed
for passengers. They should ride in their seats with their seat belts prop-
erly fastened. Otherwise, they are much more likely to suffer death or seri-
ous bodily injury, in the event of sudden braking, sudden swerving or an
accident.
■ Load and distribution
● Do not overload your vehicle.
● Do not apply loads unevenly.
Improper loading may cause deterioration of steering or braking control
which may cause death or serious injury.

2424-4. Refueling
AYGO_OM_Europe_OM9A012E
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any stat ic electricity. It is important to
discharge static electricity before re fueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■ When refueling
Observe the following precautions to pr event fuel overflowing from the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically clicks off.
● Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

Maintenance and care
AYGO_OM_Europe_OM9A012E
WARNING
■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.
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.
● Hold the support protector area to pre-
vent burns.
