CAUTION
■Burns
● Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping drugs, cold remedies, etc.)
● Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
● Do not use seat heater more than necessary. Doing so may cause minor
burns or overheating.
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 12-volt battery discharge
Turn the seat heaters/seat ventilators off when the hybrid system is off.
