anyone in the following categories comes in
contact with the steering wheel and seats when the heater is on:
• Babies, small children, the elderly, the sick and the physically challenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping drugs, cold
remedies, etc.)
●Observe the following precautions to prevent minor burns or overheating:
• Do not cover the seat with a blanket or cushion when using the seat heater.
• Do not use seat heater more than necessary.
NOTICE
●To prevent damage to the seat heaters/seat ventilators, do not put heavy objects that
have an uneven surface on the seat and do not stick sharp objects (needles, nails, etc.)
into the seat.
●To prevent battery discharge, do not use the functions when the engine is not running.
