WARNING
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other
than P (continuously variable
transmission) or N, the vehicle
may accelerate suddenly and
unexpectedly, causing an acci-
dent.
●Vehicles with a continuously
variable transmission: In order
to prevent accidents due to the
vehicle rolling away, always
keep depressing the brake
pedal while the engine is run-
ning, and apply the parking
brake as necessary.
●If the vehicle is stopped on an
incline, in order to prevent acci-
dents caused by the vehicle roll-
ing 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 fol-
lowing:
• 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 cir-
cuit 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
vehicle.
●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, caus-
ing a fire.
●Vehicles with a continuously
variable transmission: Always
apply the parking brake, shift
the shift lever to P, stop the
engine and lock the vehicle.
Do not leave the vehicle unat-
tended while the engine is run-
ning.
If the vehicle is parked with the
shift lever in P but the parking
brake is not set, the vehicle may
start to move, possibly leading
to an accident.
Vehicles with a manual trans-
mission: Always apply the park-
ing brake, stop the engine and
lock the vehicle.
Do not leave the vehicle unat-
tended while the engine is run-
ning.

1404-1. Before driving
COROLLA_U
WARNING
●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 vehi-
cle
Always turn the engine off. Other-
wise, if you accidentally move the
shift lever or depress the acceler-
ator pedal, this could cause an
accident or fire due to engine
overheating. Additionally, if the
vehicle is parked in a poorly venti-
lated area, exhaust gases may
collect and enter the vehicle, lead-
ing 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 brak-
ing.
In this case, braking is still pos-
sible, but the brake pedal
should be depressed more
firmly than usual. Also, the brak-
ing 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.
■If the vehicle becomes stuck
Do not spin the wheels exces-
sively when a driven wheel is up
in the air, or the vehicle is stuck in
sand, mud, etc. This may damage
the driveline components or pro-
pel the vehicle forward or back-
ward, causing an accident.
NOTICE
■When driving the vehicle
(vehicles with a continuously
variable transmission)
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the engine output.
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■When driving the vehicle
(vehicles with a manual trans-
mission)
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the engine output.
●Do not shift gears unless the
clutch pedal is fully depressed.
After shifting, do not release the
clutch pedal abruptly. Doing so
may damage the clutch, trans-
mission and gears.

WARNING
■Things that must not be car-
ried in the trunk
The following things may cause a
fire if loaded in the trunk:
●Receptacles containing gaso-
line
●Aerosol cans
■Storage precautions
Observe the following precau-
tions.
Failure to do so may prevent the
pedals from being depressed
properly, may block the driver’s
vision, or may result in items hit-
ting the driver or passengers, pos-
sibly causing an accident.
●Stow cargo and luggage in the
trunk whenever possible.
●To prevent cargo and luggage
from sliding forward during
braking, do not stack anything in
the enlarged trunk. Keep cargo
and luggage low, as close to the
floor as possible.
●When you fold down the rear
seats, long items should not be
placed directly behind the front
seats.
●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 package tray
• On the instrument panel
• On the dashboard
●Secure all items in the occupant
compartment.
●Never allow anyone to ride in
the enlarged trunk. It is not
designed for passengers. They
should ride in their seats with
their seat belts properly fas-
tened.
■Capacity and distribution
●Do not exceed the maximum
axle weight rati ng or the total
vehicle weight rating.
●Even if the total load of occu-
pant’s weight and the cargo
load is less than the total load
capacity, do not apply the load
unevenly. Improper loading may
cause deterioration of steering
or braking control which may
cause death or serious injury.

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 sur-
face to discharge any static
electricity. It is important to dis-
charge static electricity before
refueling because sparks result-
ing 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 possi-
ble ignition hazard.
■When refueling
Observe the following precautions
to prevent 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.
