YARIS_GRMN_OM_Europe_OM52J40E
WARNING
■When folding the rear seatbacks down
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Do not fold the seatbacks down while driving.
● Stop the vehicle on level ground, set the parking brake and shift the shift
lever to N.
● Do not allow anyone to sit on a folded seatback or in the luggage compart-
ment while driving.
● Do not allow children to enter the luggage compartment.
● Do not allow anyone to sit on the rear center seat if the rear right seat is
folded down, as the seat belt buckle for the rear center seat belt is then
concealed under the folded seat and cannot be used.
● Be careful not to catch your hand when folding the rear seatbacks.
● Depending on the position of the front seat, it may interfere when trying to
fold down the rear seatbacks. If this happens, adjust the position of the
front seat.
■ After returning the rear seatback to the upright position
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Check that the seat belts are not twisted or caught in the seatback.
NOTICE
■Stowing the seat belts
The seat belts and the buckles must be stowed before you fold down the
rear seatbacks.
● Make sure that the seatback is securely
locked in position by lightly pushing it
back and forth.
If the seatback is not securely locked,
the red marking will be visible on the
seatback lock release knob. Make sure
that the red marking is not visible.

■After adjusting the steering wheel
Make sure that the steering wheel is securely locked.
The horn may not sound if the steering wheel is not securely locked.
WARNING
■ Caution while driving
Do not adjust the steering wheel while driving.
Doing so may cause the driver to mishandle the vehicle and cause an acci-
dent, resulting in death or serious injury.
■ After adjusting the steering wheel
Make sure that the steering wheel is securely locked.
Otherwise, the steering wheel may move suddenly, possibly causing an
accident and resulting in death or serious injury.

1804-1. Before driving
YARIS_GRMN_OM_Europe_OM52J40E
WARNING
■If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as
possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle w hen the wear limits of the brake pads
and/or those of the brake discs are exceeded.
■ 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.
● 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 rupture, 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.

Driving
YARIS_GRMN_OM_Europe_OM52J40E
WARNING
●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.
● Do not touch the exhaust pipes while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
■ 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 power brake assist function 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
• 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 place 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.
