RX350/270_EE
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 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 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 engine and lock
the vehicle.
Do not leave the vehicle unattended while the engine is running.
●Do not touch the exhaust pipes while the engine is running or immediately after
turning the engine off.
Doing so may cause burns.
●Do not leave the engine running in an area with snow build-up, or where it is
snowing. If snowbanks build up around the vehicle while the engine is running,
exhaust gases may collect and enter the vehicle. This may lead to death or a seri-
ous health hazard.
