■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehiclewhen 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 cau se the plastic lenses and plastic mate- rial 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 containerssuch as air fresheners on the instrument panel or dashboard. Adhesive discs or con- tainers 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 metallizedfilm such as a silver-colored one. Reflected sunlight may cause the glass to act as alens, causing a fire.
●Always apply the parking brake, shift the shift lever to P, stop the engine and lock thevehicle.Do not leave the vehicle unattended while the engine is running.
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.
