Driving
CAUTION
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle 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 plasticmaterial 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 com-
ponents.
●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 contain-
ers 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 metal-
lized film such as a silver-colored one. Reflected sunlight may cause the glass to
act as a lens, causing a fire.
●Always apply the parking brake, shift the shift lever to P, stop the hybrid system
and lock the vehicle.
Do not leave the vehicle unattended while the hybrid system is operating.
●Do not touch the exhaust pipes while the hybrid system is operating or immedi-
ately after turning the hybrid system off.
