Safety precautions when driving Seatbelt and SRS airbag
WARNING
All persons in the vehicle should fasten
their seatbelts BEFORE the vehicle starts to
move. Otherwise, the possibility of serious in-jury becomes greater in the event of a suddenstop or accident. To obtain maximum protection in the event
of an accident, the driver and all passengers in the vehicle should always wear seatbelts when the vehicle is moving. The SRS (Supple-mental Restraint System) airbag does not doaway with the need to fasten seatbelts. Incombination with the seatbelts, it offers thebest combined protection in case of a serious accident. Not wearing a seatbelt increases the chanceof severe injury or death in a crash even whenthe car has the SRS airbag. The SRS airbags deploy with considerable
speed and force. Occupants who are out of proper position when the SRS airbag deploys
could suffer very serious injuries. Because

locks” section in chapter 2.
Always lock the passenger ’s windows using
the lock switch when children are riding in the
vehicle. Failure to follow this procedure couldresult in injury to a child operating the power
window. Refer to the “Windows” section in
chapter 2. Never leave unattended children in the ve-
hicle. They could accidentally injure them-
selves or others through inadvertent opera-tion of the vehicle. Also, on hot or sunny
days, temperature in a closed vehicle could
quickly become high enough to cause severe or possibly fatal injuries to them. Help prevent young children from locking
themselves in the trunk. When leaving the ve-
hicle, either close all windows and lock alldoors or cancel the inside trunk lid release. Also make certain that the trunk is closed. On hot or sunny days, the temperature in a trunkcould quickly become high enough to cause
death or serious heat-related injuries includ-ing brain damage, particularly for small chil-dren.
Carefully read the sections “Child restraint systems ”,
“ SRS airbag ”, and “Seatbelts” in chapter 1 of this owner’
s manual for instructions and precautions
concerning the child restraint system, seatbelt sys-tem and SRS airbag system.
Engine exhaust gas (carbon monoxide)
WARNING
Never inhale engine exhaust gas. Engine ex-
haust gas contains carbon monoxide, a color-
less and odorless gas which is dangerous, oreven lethal, if inhaled. Always properly maintain the engine ex-
haust system to prevent engine exhaust gasfrom entering the vehicle. Never run the engine in a closed space,
such as a garage, except for the brief timeneeded to drive the vehicle in or out of it. Avoid remaining in a parked vehicle for a
lengthy time while the engine is running. Ifthat is unavoidable, then use the ventilationfan to force fresh air into the vehicle. Always keep the front ventilator inlet grille
free from snow, leaves or other obstructionsto ensure that the ventilation system always
works properly.

Driving with pets
Unrestrained pets can interfere with your driving and
distract your attention from driving. In a collision or
sudden stop, unrestrained pets or cages can be
thrown around inside the vehicle and hurt you or
your passengers. Besides, the pets can be hurt un-der these situations. It is also for their own safety
that pets should be properly restrained in your
vehicle. Restrain a pet with a special traveling har-
ness which can be secured to the rear seat with a
seatbelt or use a pet carrier which can be secured
to the rear seat by routing a seatbelt through the
carrier’ s handle. Never restrain pets or pet carriers
in the front passenger ’s seat. For further information,
consult your veterinarian, local animal protection so-ciety or pet shop.
Tire pressures
Check and, if necessary, adjust the pressure of
each tire (including the spare) at least once a month
and before any long journey.
Check the tire pressure when the tires are cold. Use
a pressure gauge to adjust the tire pressures to the
values shown on the tire placard. Refer to the “Tires and wheels ” section in chapter 11
for detailed information.WARNING
Driving at high speeds with excessively low tire pressures can cause the tires to deform
severely and to rapidly become hot. A sharp
increase in temperature could cause tread
separation, and destruction of the tires. The resulting loss of vehicle control could lead toan accident.
California proposition 65 warning
WARNING
Engine exhaust, some of its constituents, and certain vehicle components contain or emit
chemicals known to the State of California to
cause cancer and birth defects or other repro-ductive harm.
